Remote monitoring device and method for two-wire centralized power supply

Abstract

The invention discloses a remote monitoring device and method for two-wire centralized power supply. The remote monitoring device comprises a power supply module, two core wires, a management control module and a plurality of remote monitoring modules. According to the remote monitoring device and method, the two core wires are used for supplying power to the multiple remote monitoring modules so as to reduce various costs, overcurrent detection protection is carried out on the remote monitoring device through the current limiting starting unit, and the remote monitoring device and method improve the safety of a power supply on the premise that cost input is considered; furthermore, according to the remote monitoring device and method, a remote monitoring module with a low-power-consumption WIFI unit is arranged, so that the power consumption of centralized power supply is reduced; furthermore, according to the remote monitoring device and method, the power supply module is connected with each remote monitoring module through two core wires in a star-shaped manner, so that the networking complexity is reduced, and the use and expansion convenience is improved.

Description

technical field [0001] The invention relates to the field of remote monitoring of two-wire centralized power supply, and relates to a remote monitoring device and method of two-wire centralized power supply. Background technique [0002] Remote monitoring can usually include two parts: one is remote monitoring, and the other is remote control. Among them, monitoring includes monitoring of the environment, computer systems and network equipment, that is, obtaining information through the network; and remote control refers to the method of operating remote computers or similar equipment through network communication. It includes operations such as restarting and shutting down the remote computer, as well as the work of controlling or setting the remote computer. In practical applications, remote monitoring is not only used in ordinary computers, but also in devices or equipment with communication functions such as microchips, so as to realize various remote functions through ...

AI Technical Summary

Problems solved by technology

[0004]However, the existing technology still has the following defects: 1. In the existing remote monitoring system with WIFI, if the external power supply is not added, the system will give The power supply is under pressure, which affects the life of the system power supply; increasing the external power supply to ensure the operation of the system will virtually increase the cost of the entire system, that is, the existing technology cannot take into account the cost and the health of the power supply; 2. The degree of networking is complicated and the convenience is poor ;3. Need to wake up the main WIFI chip repeatedly, the power consumption is too strong
