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 peripherals to provide various auxiliary equipment and devices. The design of the control system is complex, the wiring engineering is large, the system stability is not high, there are many fault points, and remote control cannot be realized. , Unable to realize linkage control between multiple devices

[0004] At present, a small number of manufacturers have targetedly designed integrated automatic control equipment, which can realize remote switch control of AC power supply and distribution equipment, and also integrate loop current detection functions, switch value detection, switch value output, and remote control in the equipment. Various functions such as meter reading, backup battery power supply, etc., but in order to pursue large and complete functions, these devices are large in size and high in manufacturing cost. The number of control and management circuits is fixed at 6 or 12, but in actual use, In order to save costs, most of the AC power supply and distribution facilities have a relatively compact cabinet design, there is not enough space to install this integrated control equipment, and other functions of these integrated control equipment are not available; and A huge number of AC power supply and distribution facilities have only 2-4 power supply and distribution circuits, and the use of integrated control equipment is a serious waste
