Problems solved by technology

[0002] Most of the existing street lamp control methods are to centralize and regularly control the switch status. The laying and maintenance of the lines require a lot of manpower and financial resources. At the same time, whether the street lamps are normal can only be checked manually, which is extremely inconvenient for the management of street lamps. It is also easy to cause power loss, so it is necessary to improve the street lamp control method
[0003] "Energy-saving intelligent lighting control system" patent (publication number CN14044347) uses computers to control the entire street lighting system, which can realize energy-saving control of street lighting, but cannot realize intelligent control according to changes in natural light and noise

Embodiment Construction

[0018] Such as figure 1 As shown, multiple street lamps are connected in series to the primary side of the variable reactance converter, and the power conversion unit and the secondary side of the variable reactance converter form a secondary impedance conversion circuit. The primary impedance can be changed by changing the secondary impedance The proportional relationship with the load impedance realizes the soft start of street lamps and voltage regulation and energy saving. The power conversion unit is composed of power electronic power devices, trigger controllers, signal detection and processors, etc., which is an existing technology, and controls the current of the secondary coil of the variable reactance converter by adjusting the control angle of the thyristor.

[0019] The main intelligent controller judges according to the collected signal, sends a control signal to the slave intelligent controller through wireless communication, and the slave intelligent controller ...

Abstract

The invention relates to an intelligent street lamp control method based on wireless networks. According to the method, a plurality of street lamps are connected to a primary side of a variable reactance converter after being connected in series, and one set of wireless network is composed of a plurality of street lamps; each set of wireless communication network is provided with a main intelligent controller and an auxiliary intelligent controller, each street lamp is provided with a sensor used for collecting signals, collected signals are transmitted to the main intelligent controllers in a wireless communication mode, the main intelligent controllers conduct judging according to the collected signals and send control signals to the auxiliary intelligent controllers in a wireless communication mode, the auxiliary intelligent controllers control power conversion units, the power conversion units enable secondary impedance of the variable reactance converter to change, and therefore control over the street lamps is achieved.

technical field [0001] The invention relates to a wireless network-based intelligent control method for street lamps. Background technique [0002] Most of the existing street lamp control methods are to centralize and regularly control the switch status. The laying and maintenance of the lines require a lot of manpower and financial resources. At the same time, whether the street lamps are normal can only be checked manually, which is extremely inconvenient for the management of street lamps. It is also easy to cause power loss, so it is necessary to improve the street lamp control method. [0003] The "Energy-saving Intelligent Lighting Control System" patent (publication number CN14044347) uses a computer to control the entire street lighting system, which can realize energy-saving control of street lighting, but cannot achieve intelligent control based on changes in natural light and noise. The patent of "monitoring and energy-saving device for single lamp of street lam...
