Coal mine safety monitoring substation fault diagnosis and voice alarm method

Abstract

The invention provides a coal mine safety monitoring substation fault diagnosis and voice alarm method, and the method comprises the steps: sequentially carrying out the fault diagnosis of a power module, an information storage module, a data storage module and a clock module after a substation is powered on, carrying out the voice alarm through a voice alarm module under the condition that any module breaks down, and under the condition that all the modules are normal, entering a normal working process which includes fault diagnosis of a display screen module, a sub-control module, a CAN communication module and a TCP / IP communication module. According to the method, self-diagnosis and self-identification of faults of each component module of the coal mine safety monitoring substation can be realized, voice alarm is carried out through the voice alarm module, a user is prompted to carry out timely maintenance, operation of maintenance personnel is facilitated through self-diagnosis of the faults, the fault maintenance time is shortened, the timeliness of operation of management personnel is ensured through voice prompt, further development and expansion of potential safety hazards can be avoided, and the production safety of a coal mine is improved.

Description

technical field [0001] The application relates to the field of coal mine monitoring and safety technology, in particular to a fault diagnosis and voice alarm method of a coal mine safety monitoring substation. Background technique [0002] The application of the coal mine safety monitoring system has played a very important role in the safety production of the coal mine. Generally, coal mines install a set of coal mine safety monitoring system, and underground switches, monitoring substations, dozens of sensors and other hundreds of devices need to be installed underground. Coal mines arrange special departments and personnel to be on duty every day for system management and equipment maintenance. [0003] If the safety monitoring system fails, on-site maintenance personnel are required to check sensors, lines, substations, switches and other equipment one by one, which often takes a long time to troubleshoot, requires a large maintenance workload, and is relatively ineffici...
