Abstract

The invention relates to a safety monitoring terminal device for a mine motor and belongs to the field of monitoring, and the device provided by the invention is designed for solving the problem that monitoring through the existing mine motor can not transmit acquired data to technical staff immediately. The safety monitoring terminal device comprises a single-chip microcomputer processing module, a field data acquisition module, a failure execution module, a communication processing module, a human-computer interaction module and an I2C (intel-integrated circuit) interface peripheral module, wherein the communication processing module comprises a wireless communication module and a 485 communication module, the human-computer interaction module comprises a keyboard interface circuit and a liquid crystal display circuit, and the I2C interface peripheral module comprises a system calendar circuit and an external expansion storage circuit; the field data acquisition module is used for acquiring the three-phase alternating current voltage, alternating current and frequency of the motor and sending to the single-chip microcomputer processing module, and the acquired data is sent to a PC (personal computer) of a monitoring center through the 485 communication module; the wireless communication module is used for sending short messages to a mobile phone user of a monitoring center through a GSM (global system for mobile communication) network; and the output end of the failure execution module is connected with the control end of a contactor used for controlling the operation of the motor.

Description

technical field [0001] The invention relates to a mine motor safety monitoring terminal device, which belongs to the field of monitoring. Background technique [0002] The working environment of the mine is very harsh, and the damage ratio of electrical equipment is relatively high. Moreover, there is a certain distance between the monitoring room and the work site in the mine environment, and the existing mine motor protection and monitoring systems all use wired transmission to collect data. This setting method leads to low real-time data communication and low anti-interference ability, and most of the motor protection systems used in existing mines are JDB series protectors installed in explosion-proof vacuum magnetic starters. Most of the integrated protectors are independent components, the accuracy of the analog circuit is poor, and the failure rate is high. And the data can only be uploaded to the PC in the monitoring room, and cannot be transmitted to relevant leade...
