Intelligent wireless remote-controlled power switch device

Abstract

The invention provides an intelligent wireless remote-controlled power switch device comprising a main control module, a GPRS module, a relay, and a power module, wherein the GPRS module is connected with the main control module and is provided with a wireless communication antenna; the power module provides working voltage; the GPRS module is a general GPRS network access module and is internally provided with a handset SIM intelligent card with a GPRS service function; the GPRS module can carry out communication with the main control module by RXD signal wires and TXD signal wires and transmits data of a control module to a commanding center server in a GPRS way by Internet network access, thus realizing bidirectional transmission; in the device, the communication between an Internet and a central server is established by the online access of a GPRS; the related information such as voltage current and leakage current of the working power supply of equipment can be sent to the central server in real time; the setting or the adjustment on a working parameter (particular on the action threshold of the current leakage protection) can be carried out according to instructions given bythe central server, thus adapting to different weather conditions.

Description

technical field [0001] The invention relates to a power switch control device, in particular to an intelligent wireless remote control power switch device for on-line remote control through a wireless network. Background technique [0002] With the rapid development of computer technology and communication technology, more and more high-tech applications have been applied to the fields of electronic police, public security checkpoints, and intelligent transportation, which has improved the technological content, accuracy, and reliability of related systems, and greatly reduced human labor. strength. The normal operation of electronic equipment in various systems in this field is inseparable from the power supply. A reliable and controllable power supply is one of the most important key components for the normal operation of the electronic equipment in the above system.

AI Technical Summary

Problems solved by technology

[0003] Conventional power supply can be divided into three categories. The first category is air switch, with overcurrent and leakage protection. The disadvantage is that after the protection is disconnected, manual closing is required and the leakage threshold cannot be changed; the second category is remote control power supply. It can be remotely controlled, can upload parameters such as voltage, current, and power, and can remotely control the power switch. It generally uses radio stations to transmit control instructions, but it does not have leakage protection and overcurrent protection; the third type is simple intelligent power supply with overcurrent protection. And leakage protection, it can automatically close 3-5 times after fault protection, but it will not act after 5 attempts, manual intervention is still required, and the leakage threshold cannot be changed

In the field power supply lines, due to rain, snow, high temperature, etc., the leakage is larger than that in the dry state, and the above three types of power sources often have frequent tripping protection, especially the second type usually has no leakage protection, so the above three types of power sources cannot be used very quickly. Well adapted to the harsh environment in the wild
