By chance, I came across the single-color temperature smart dimming driver that we have been looking for. The main living room lights and ceiling lamps mainly produced by our company are instantly dazzling. They can not only be infinitely dimmed, but also flicker-free throughout the process, and can also be controlled remotely.
In order to understand smart homes, as well as supporting products and services, I have been talking about smart switches in the past few days. Some people say that single-fire smart wall switches cannot be connected to smart dimmer lights, or even some ordinary LED lights. Is this true?
Controllable switch + home circuit = smart switch?
Since the switch controls the light on and off, the smart switch intelligently controls the light on and off. So, does the home circuit + controllable switch become a smart switch? From this, can remote control and electrical equipment linkage be achieved? Let's explore this issue below.
Replace the mechanical switch directly with an intelligent control module
When the module is disconnected, the module itself loses power and the entire circuit is disconnected, making it impossible to remotely turn the switch on again. It's a bit like locking yourself out without a key when you go out, so this method is unreliable. Directly adding a device to the switch that receives instructions and controls it cannot achieve the effect of a smart switch.
It can be seen that controllable switch + neutral line transformation + household circuit = zero fire intelligent switch circuit
In the above circuit, because the controllable switch cuts off its own current after disconnecting the circuit, does the formula of controllable switch + neutral line + household circuit work?
Add a neutral line to the switch so that the switch has an independent circuit, so that the switch can supply power independently, and the line switch of the light will not affect the switch operation. This is the zero-fire switch solution.
The formula of controllable switch + neutral line transformation + household circuit = zero fire smart switch circuit is feasible.
Controllable switch + live wire modification + home circuit = single fire intelligent switch circuit
In addition to the neutral wire, household circuits also have live wires. Since transforming the neutral wire can achieve the effect of smart switching, is it also possible to transform the live wire? That is, controllable switch + live wire modification + household circuit. Is this formula feasible?
By modifying the circuit: instead of using mechanical switches to physically disconnect the circuit, add loads to the switch and lamp circuits. When the switch is closed, due to the load, only a small current passes through the switch and the bulb. The current passing through is too small to light the bulb while maintaining the switch operation. This solves the problem of a single fire switch.
However, it should be noted that the load must ensure that the current passing through it is small enough to not light up the bulb while maintaining the switch operation. Therefore, the single-fire switch has certain requirements for the power of the lamp. If the power of the lamp is too small, it will be easily lit or flicker by the small current passing through (this is also the reason why the single-fire switch load lamp on the market generally has a minimum power of 3W), and It is also necessary to pay attention to the rated power of each circuit of the single-fire switch.
A large part of automotive electronic products now is compatibility design for different car companies. No matter how compatible it is internally, when it comes to external requirements, it is necessary to determine the connection interface requirements, including installation location, structure and electrical content. One prominent problem is Connector selection. Automotive connectors and wiring harnesses are carriers for controlling electrical signals in automobiles. They organically connect vehicle central control components with automobile control units, electrical and electronic execution units, and electrical devices to form a complete automobile electrical and electronic control system.
(1) The content and quantity of automotive connectors and wiring harnesses in in-car electronic technology is also an important indicator of car function and performance.
(2) Automotive connectors, a single vehicle requires approximately 200 wire harnesses and more than 350 connectors
Figure 1 The whole vehicle wiring harness design requires a lot of connections.
When we choose a connector, we first need to consider the particularity of the automotive connector. Automotive connectors are also subject to standards set by different vehicle companies. The basic international standard is ISO 8092-2005, which is divided into four parts:
(1) ISO 8092.1 Dimensions and special requirements for single-wire chip connectors
(2) ISO 8092.2 definition, test methods and general performance requirements
(3) ISO 8092.3 Dimensions and special requirements for multi-wire chip connectors
(4) ISO 8092.4 Cylindrical plug connectors for single-wire and multi-wire plug-in connections Dimensions and special requirements
Since international standards are the result of games, many things are determined by manufacturers as a basic direction. However, the test parameters, test items and test methods are no longer in line with the current development status of connectors, so they are basically divided into three regional standards. Represents some of the requirements of the US, European and Japanese automotive industries.
1) The connector performance specification USCAR-2 formulated by the American Society of Automotive Engineers can represent the development status of connectors in terms of test parameters and test items, and is more operable in terms of test methods. Standards such as GM's GMW3191 and Fiat's 7-Z8260 are all written based on USCAR-2.
2) JASO D605-1996 Automotive Electronics Connector: The Japan Automobile Manufacturers Association has also developed a basic connector standard based on the comprehensive needs of Japanese car companies.
3) LV 124 Test items, test conditions and test requirements for automotive electrical and electronic components under 3.5 tons. This supply specification is prepared by representatives of the car manufacturers Audi AG, BMW AG, Daimler AG, Porsche AG and Volkswagen AG Compiled, this is also a joint enterprise standard representing the German automotive industry.
In fact, due to the actual situation of automotive connectors, we also choose larger ones rather than smaller ones, because there are actually more potential troubles caused by connector selection issues. Therefore, we not only refer to the standard system, but also select suppliers based on rankings.

When it comes to how freight forwarders develop overseas designated cargo markets, many friends have sent private messages asking for advice since last year. However, since I didn’t make my debut in designated cargo, I have never written about related topics, and I don’t have much qualifications to give advice. There are many friends and companies around me who do designated goods. In the eyes of outsiders, their profits are high, their practitioners have strong overall quality, and their income is generally higher than those who do self-delivery. They are also more likely to be criticized by foreign trade customers. If you actually understand, it is different. The size of the company, different service products, and the development methods, methods, and costs of designated goods in different regional markets are very different. If a freight forwarder starts a business from scratch and enters designated goods, the early time and cost may have already been eliminated before you can make money. You are crushed.
There is no logic in the following content. It is just a brief discussion about freight forwarding marketing and the current methods of developing overseas designated goods. It is a reference for freight forwarders who want to develop overseas markets. In fact, no matter whether domestic freight forwarding sales or overseas designated goods sales, everyone’s purpose is the same. Likewise, we find customers through various methods and use various methods to connect with customers. In essence, what we sell is neither products nor services, but our credit, so that the other party can trust our credit.
First of all, the development of designated goods requires the team to have overseas marketing capabilities. In the early days of the freight forwarding industry, all designated goods were controlled by foreign freight forwarding channels. By setting up branches in China, overseas freight consignments were directly assigned to Chinese branches for operation. The market share of designated goods was also completely controlled by large companies, and there was no need to possess Marketing, after the designated cargo volume increases, foreign freight forwarders will only get contract logistics, project logistics or some designated cargo with high interest rates. The remaining market share of designated cargo will be allocated to other companies in the freight forwarding market. Through the development of foreign agents, we Cooperate with the company and start to receive designated goods in the form of exchange. At the same time, there are also freight forwarding companies that only accept designated goods unilaterally. In this case, strong overseas marketing and customer acquisition capabilities are required, and there are risks in the account period.
Secondly, the development of designated goods requires leverage. The leverage here refers to the team and technology. Some domestic freight forwarding companies that do not have an overseas agent network will develop designated goods through exhibitions, emails, and even visits abroad in the early days. At present, low-cost online media tools, search engine optimization, keyword marketing and other technical means can be used for precise development. This includes a large number of marketing methods and work details, with different requirements for teams, positions, and division of labor, because you use the Internet This tool is also used by competitors. Due to the large amount of information, I won’t explain it here. Interested friends can chat privately.
Finally, different freight forwarding companies have different scales and product attributes, as well as marketing methods in overseas markets and marketing tools used. For example, some travel companies only take in whole groups, and some only take in split groups; some logistics companies only do truck transportation. Just like not doing LTL, we need to match and classify different target customer attributes and our own business capabilities.
When developing overseas designated goods, first ask yourself whether the freight forwarding service you provide has core competitiveness, whether it is irreplaceable for overseas agents or customers, whether it has segmentation advantages in the region and industry, and other questions. Then, you can develop target customers based on the target market. For example, if you are engaged in the international logistics of dangerous goods and your core competitiveness is the warehousing, packing, risk declaration, customs declaration, etc. of all levels of dangerous goods, you can develop similar foreign agents or customers. , and these customers also need you to assist them in completing certain tasks in the service chain in China, forming long-term strategic cooperation, which will also generate long-term profits, and minimize the development of new customers and stable designated cargo business.
The above content is simple and ordinary, nothing special. In fact, the sales staff who developed designated goods in the early days simply and repeatedly used emailing to develop overseas customers every day. It is such a simple method, as long as you persevere, you will earn a monthly salary. Freight forwarding sales exceeding RMB 10,000 and freight forwarding companies with annual profits exceeding RMB 1 million. In the current Internet society, a large number of online platforms and social tools provide abundant marketing channels for developing overseas designated goods. It depends on how you discover and use them.
1. Synchronous generator excitation system
Generally speaking, a generator set consists of an engine (providing kinetic energy), a generator (generating current), and a control system. Wind turbines rely on wind power to drive the generator to rotate and generate current; hydroelectric generators use the drop of water flow to generate power to drive the generator to generate electricity. Fuel generators rely on the combustion of diesel or gasoline to generate power to drive the generator set. Although the power sources of various power generation systems may be different, they all have one important part in common, and that is the generator. The electrical energy we use in production and life comes from power plants, and they are inseparable from motors. The rotor can be driven by a water turbine, steam turbine, internal combustion engine, etc. The main components are shown in the figure below.
Currently, 99% of the electrical energy used by humans is generated by synchronous generators. In order to achieve energy conversion, a synchronous generator needs a DC magnetic field. The DC current that generates this magnetic field is called the excitation current of the generator. According to the supply method of the excitation current, any generator that obtains the excitation current from other power sources is called a separately excited generator, and a generator that obtains the excitation power from the generator itself is called a self-excited generator.
The excitation system of a synchronous generator generally consists of two parts. One part is used to provide DC current to the field winding of the generator to establish a DC magnetic field, which is usually called the excitation power output part (or power unit). The other part is used to adjust the excitation current during normal operation or in the event of an accident to meet operational needs. This part includes excitation regulator, forced excitation, forced demagnetization and automatic demagnetization, etc., and is generally called the excitation control part (or control unit).
2. Synchronous generator voltage regulation
Maintaining the terminal voltage of the generator equal to a given value is the main means of voltage regulation in the power system. So how to ensure that the terminal voltage of the synchronous generator is a given value?
We say that when the load changes, the excitation must be adjusted. Let's analyze its specific principle using the simplified phasor diagram of the generator.
From the above figure we can get:
In the formula: Eq——the no-load potential of the generator; Uf——the terminal voltage of the generator; If——the load current ratio of the generator.
The above formula shows that when the generator no-load potential Eq is constant, the generator terminal voltage Uf will decrease with the increase of the load current If. In order to ensure that the generator terminal voltage Uf is constant, it must increase with the increase of the generator load current If. Increase (or decrease), increase (or decrease) the no-load potential Eq of the generator, and Eq is a function of the generator excitation current Ifq (if saturation is not considered, Eq and Ifq are proportional), so when the generator is running As the generator load current changes, the excitation current must be adjusted to keep the generator terminal voltage constant.
For metal button switches, during the entire application process, if the light does not light up, this problem needs to be solved immediately to avoid hidden dangers. So how to solve the problem that the indicator light of the metal button switch does not light up? Let’s introduce it to you below.
In different household appliance workplaces, because the circuit line control circuit is very long, the indicator light is not very bright, mostly caused by induced voltage.
1. Insert a small volume size 0.01_0.22UF middle input terminal into the input and output terminal of the distribution line, and then connect a 100k_500k resistor. The actual operation is inconvenient.
WINDOO quick-plug button switch-indicator light high current
2. Add an RC circuit. Many AC contactors also have their electromagnetic coils connected on both sides. Its function is to digest and absorb induced current. This is also a very effective solution.
3. Each display light uses a shielded cable, but it is not very beautiful.
4. Modification of the resistance-capacitance absorber is simple, convenient and cheap.
Therefore, if the indicator light of the metal button switch does not light up, it can be solved in this way.
After reading the above article about ‘How to solve the problem when the indicator light of the metal button switch does not light up’, you will know what is going on next time you encounter it, and you can even solve this problem yourself. You can also consult us for more related questions.
