In this embodiment, the power data may include the voltage, current, zero-sequence voltage, zero-sequence current, active power, reactive power, power factor, insulation resistance, power consumption and other parameters of each circuit of the power system. The power monitoring station 2 is used to inspect the comprehensive protector in real time and receive the power data transmitted by the comprehensive protector. The monitoring host 3 is located above the ground and is internally provided with monitoring software, which is the core of the monitoring system. The switch 4 is used to realize data exchange between the monitoring host 3 and the power monitoring station 2. The mobile phone terminal is used to quickly query and monitor the monitoring system. The printer 6 and the UPS power supply 7 are connected to the monitoring host 3.

[0032] Specifically, the monitoring host 3 of the mine power supply and distribution power monitoring system of this embodiment is set in the mine dispatching command center, and the power monitoring station 2 integrates computer technology and network technology to achieve unmanned operation of the underground substation, which is suitable for underground places with gas and coal dust explosion hazards.

[0041] The graphic display module is used to display the power data passing through the data acquisition module. The graphic display module is mainly used to display the instantaneous value and historical record of the power data. Specifically, the monitoring system uses the graphic display module to display the changes of the power data in real time on the ground in a graphical manner, and displays the real-time curve and historical curve of the power data. In this way, the graphic display module enables the real-time curves of the power data of multiple measuring points to be displayed on the same display screen at the same time, and is provided with a time scale.

[0042] The alarm module is used to provide alarms. When the power data is abnormal, the alarm module will sound an alarm and record the fault value in the event log, thereby ensuring the normal operation of the monitoring system.

When the monitoring host 3 is down, the monitoring standby machine 5 in the dual machine can automatically take over the business of the monitoring host 3, thereby ensuring that the system can continue to provide services without manual intervention. Specifically, when the monitoring host 3 is working normally, data can be exchanged between the monitoring host 3 and the monitoring standby machine 5. When the monitoring host 3 is working abnormally, the monitoring standby machine 5 immediately executes the function of the monitoring host 3 to send a data reading instruction to each substation and prompt the user with the current fault information.
