A new method of municipal energy saving and consumption reduction-street lamp controller

With the development of the international industrial economy, the rapid increase in population, the unlimited rise of human desires and the unrestrained methods of production and life, the international climate is facing more and more serious problems, low-carbon marked by low energy consumption, low pollution, and low emissions. The economic era has come to a missed appointment and is profoundly changing our lives.

　　 1. When we develop products, we need to understand the current status and development trend of domestic and foreign street lamp controller technology. The foresight of the plan is one of the conditions for the product to stand in the market.

　　 According to the investigation, the street lights at home and abroad are mainly controlled by wireless monitoring systems. The monitoring system selects wireless private network or mobile public network for communication. It can complete multiple functions such as remote control, remote viewing, remote measurement, remote adjustment, remote signaling, and alarm. Greatly improve the level of street lamp processing, which not only increases the operating power but also reduces the processing cost, which will be the development trend of street lamp processing in the future. However, the cost of the system is high, ranging from hundreds of thousands of yuan to millions of yuan. Moreover, its system technology is not yet thoroughly experienced, and if it is put into use, it will result in a waste of capital.

　　 1. Know the current situation of domestic street lamp control

　　 At present, most of the domestic street lights use the microcomputer time-controlled switch control method. The basic operating principle is to control the street lights according to the artificially set light-on and light-off time; its biggest drawback is that it is bright and bright every day throughout the year. The time is different. If the street lamp time cannot be adjusted in time, it will lead to unnecessary waste of electric energy; assuming that the street lamp time is adjusted in accordance with the 'Three Electricity Office' of the bureau, the number of operations to adjust the street lamp time throughout the year is at least 26 times, evenly once every two weeks . At the same time, the risk of operational safety is correspondingly increased.

　　 2. Complete the street light controller transformation process

　　According to the current situation of domestic street lamp control and the actual situation of the products developed by Abs, we have carried out an exploration test for street lamp control transformation, so that the street lamp control will automatically and accurately light up and stop according to the change of sunrise and sunset time every day. This can greatly reduce power waste. And the remote control method is added to the function, and the switch and brightness of the street light can be adjusted through the PC and mobile APP.

　　 1. Use light control switch to control

　　 First of all, what we think of is the use of light-controlled switches to control the on and off of street lights. The light-controlled switches are mainly composed of photoresistors and integrated circuits. When the sunlight is strong in daylight, the photoresistor presents a low resistance condition, so that the relay of the integrated circuit does not work and the street lamp does not light up. At dusk, the light is weakened, the photoresistor presents high resistance, and the relay attracts the street lamp to light, thus completing the automatic control of the street lamp. The intention to save energy. However, after testing on-site devices, it is found that if the sky is dim occasionally, leaves and other objects blocked the photosensitive element for a short time, or flashlights, cars, and other lights irradiate the photosensitive elements, the light-control switch will be turned on and off by mistake, which is a requirement for the environment. The conditions are higher.

　　2. The shortcomings of light-controlled switches are dealt with by installing time-controlled switches

　　According to the characteristics of light-controlled switches and the conditions of existing street lamp control equipment, we decided to combine light-controlled switches and time-controlled switches to complement each other's advantages and disadvantages. The light-controlled switch is further improved, and the delay function is added to deal with the malfunction caused by short-time blocking and irradiating the photosensitive element. Set the switching time of the time-controlled switch to the maximum time distance in one year, that is, the earliest light-on time and the latest light-off time, so as to deal with the phenomenon that the light-controlled switch is turned on and off by mistake before the time is up. However, the problem of high requirements for the installation environment is still not well dealt with.

　　3. Use the latitude and longitude street light controller to complete the best control intention

　　 Combining the technical problems we encountered, we continued to explore and practice, and found that the latitude and longitude street lamp controller can handle the automatic and accurate lighting and stopping of the street lamp. There is no light control device with high environmental requirements and time-controlled operation processing. Complex problems. It uses advanced embedded microcomputer control technology, can change the rules according to the seasons of the year, combine the local latitude and longitude and the time and date to calculate the sunrise and sunset time, and automatically confirm the switch time of the street light. The latitude and longitude of any region in the world are the only ones, which overcomes the shortcomings of general time-controlled switches that need to manually adjust the light on and off time.
