Problems solved by technology

[0002] In the current power grid erection, unattended substations have been widely used. The establishment of the centralized control center enables the management and operation tasks of the substation to be realized remotely by the centralized control center, and the operators do not need to enter the substation site. In this mode, the substation’s All monitoring information needs to be uploaded to the centralized control center, and the remote control and remote adjustment operation commands issued by the centralized control center directly reach the on-site actuators of the substation to control the actions of on-site equipment. However, in the existing power equipment safety monitoring system, serial Data transmission, not only complex wiring, difficult maintenance, but also high power consumption, poor stability of system operation

Abstract

The invention discloses a power equipment safety monitoring system based on a wireless network. The power equipment safety monitoring system comprises an equipment monitoring unit, a wireless receiving-transmitting module, a main wireless transceiver, a remote monitoring platform, an alarm device and an intelligent mobile terminal, wherein the equipment monitoring unit and the wireless receiving-transmitting module are arranged in each piece of power equipment; two kinds of wireless receiving-transmitting modules are arranged in the power equipment; one kind of wireless receiving-transmitting module comprises a wireless transceiver; and the other kind of wireless receiving-transmitting module comprises a relay wireless transceiver. In the power equipment safety monitoring system, 5 to 10 pieces of power equipment are divided into a group, and the wireless receiving-transmitting module in one piece of power equipment in each group communicates with the main wireless transceiver of the system, so that the power consumption of a source wireless transceiver is lowered; the data transmission capability of the power equipment safety monitoring system is enhanced; and the power equipment safety monitoring system runs more stably. Moreover, when the remote monitoring platform monitors that certain power equipment encounters an exception, maintenance personnel can go to the exceptional power equipment to repair in time no matter where the maintenance personnel is, so that the repair time of the power equipment is saved.
