In places where a large number of high pole lamps are used, if dozens of high pole lamps are installed, if the original method of independent power transmission for each high pole lamp and clock control switch control are also used for lighting, the controllability is poor, and the site lighting time and lighting method cannot be changed in real time according to the actual production needs, and the high pole lamps cannot be monitored in real time, resulting in waste of electric energy and shortening the lamp life. When the high pole lamp breaks down, it can neither alarm nor indicate the place where the fault breaks down, which is not convenient for maintenance. After studying the relevant information, the author believes that the wireless communication remote monitoring high pole lamp system can deal with these problems well. Try as follows:

1 System scheme

System requirements:

(1) Ensure excellent real-time communication between each substation (terminal unit) and the main control center station in the whole area where the high pole lamp operates.

(2) Monitor the operation of high pole lamps.

(3) It has strong anti-interference ability and can ensure reliable communication under adverse weather conditions.

(4) The high pole lamp can be freely divided into several areas and controlled by areas.

(5) There are active and manual control methods.

(6) It has the function of punctuality, and can actively start the high pole lamps in different areas for lighting.

(7) It has the function of fault alarm. When a fault occurs, it can alarm on the upper computer.

(8) Local/centralized control is optional, facilitating maintenance and emergency operation.

According to the characteristics of various communication methods, as well as the actual conditions and system requirements of high pole lamps, the supervisory control and data collection system is selected

acquisition,SCADA)。 It is an automated system of monitoring, control and dispatching management based on computers, which can complete long-distance data collection, equipment control, measurement, parameter adjustment, signal alarm and other functions, and is suitable for point-to-point and point to multipoint operating environments. PLC is selected to control the high pole lamp through the contactor, and the current of each phase is collected through the current transmitter. Wireless communication method is selected for communication between different substations. The upper computer is added to show the lighting condition, and the upper computer is used for long-distance monitoring and control. The modular high pole lamp control box with built-in PLC, air switch, contactor, current transmitter, etc. is selected as the long distance terminal unit high pole lamp control system.
