Description

technical field [0001] The invention relates to the fields of the Internet of Things, road lighting and industrial control, and specifically relates to a wireless distributed monitoring method, device and system. Background technique [0002] In the field of road lighting and industrial control, there are a large number of AC power supply and distribution facilities. These AC power supply and distribution facilities distribute the input AC power to the power supply circuit, and supply power to each circuit load. Each circuit is controlled manually or by a timer. The loop switch controls the power supply. This kind of control method requires manual control or manual regular adjustment of time control, and cannot realize flexible remote automatic control. [0003] At present, although some manufacturers use PLC programmable controllers for automatic switch control of power supply and distribution circuits in order to realize automatic control, the PLC programmable controllers ...

Problems solved by technology

[0002] In the field of road lighting and industrial control, there are a large number of AC power supply and distribution facilities. These AC power supply and distribution facilities distribute the input AC power to the power supply circuit and supply power to the loads of each circuit. Each circuit is controlled manually or by a timer. The loop switch controls the power supply. This type of control method requires manual control or manual regular adjustment of the time control, and cannot achieve flexible remote automatic control.

[0003] At present, although some manufacturers use PLC programmable controllers for automatic switch control of power supply and distribution circuits in order to realize automatic control, the PLC programmable controllers have relatively small control drive capabilities, and external intermediate relays are required to achieve high-power circuit power supply. The control drive of the contactor, and the programmable controller only provides Ethernet interface and RS232, RS485 communication interface, it needs external wireless communication GPRS communication interruption to realize remote automatic control, and the programmable controller needs an additional external power supply module for its Therefore, the use of programmable controllers to realize automatic control of power supply and distribution circuits requires pe
