Abstract

The invention relates to an underground coal mine safety monitoring system, in particular to an anti-interference underground safety monitoring system. The system comprises an underground monitoring substation, an underground sensing module, an underground equipment execution module, a ground-based power module and an upper computer module, wherein a power input end, through which the monitoring substation is connected with the power module, is connected with a power anti-interference circuit; a sensing signal input end, through which the monitoring substation is connected with the underground sensing module, is connected with a signal anti-interference circuit; a control signal output end, through which the monitoring substation is connected with the underground equipment execution module, is also connected with a signal anti-interference circuit; and a remotely-transmitting signal output end, through which the monitoring substation is connected with the upper computer module, is also connected with a signal anti-interference circuit. The capacity of withstanding surge impulse voltage of the power part of the monitoring system is enhanced; and at the same time, after the signal enters the equipment, the system filters high-frequency interference, purifies effective signals and makes the equipment operation and signal transmission and control reliable.

Description

Anti-interference underground safety monitoring system
Technical field
The present invention relates to coal mine downhole safety monitoring system, specifically is a kind of anti-interference underground safety monitoring system.
Background technology
Common coal mine downhole safety supervisory system has generally included parts such as outstation, down-hole sensing module, underground equipment execution module, power module, upper computer module.In system's operational process, power module provides power supply by power lead for outstation, outstation is by the transducing signal of sensing module under the signal cable received well, and transmit monitor signal to upper computer module by signal cable, also execute instruction to the underground equipment execution module transmission by signal cable.The mechanical mining mode of mine down-hole adopts a large amount of electromechanical equipments, for energy-conservation, adopt a large amount of frequency controls or soft start equipment simultaneously, the start and stop of these equipment and operation, the very big electromagnetic interference signal of meeting produce power, by power supply, space to external radiation, because mine down-hole space constraint, safety monitoring system equipment and signal transmission cable can't completely cut off with these interference sources from the space, therefore can make system produce problems such as wrong diagnosis electricity, signal transmission abnormality, bring hidden danger to safety production monitoring.
Summary of the invention
Technical matters to be solved by this invention is, provides that a kind of antijamming capability is strong, stable signal transmission, anti-interference underground safety monitoring system reliably.
Anti-interference underground safety monitoring system of the present invention includes outstation, down-hole sensing module, the underground equipment execution module that is positioned at the down-hole, also comprises the power module, the upper computer module that are positioned at ground; The power input that described outstation is used for connecting power module is connected with a power supply anti-jamming circuit; The transducing signal input end that described outstation is used for connecting the down-hole sensing module is connected with a signal anti-jamming circuit; The control signal output ends that described outstation is used for connecting underground equipment execution module also is connected with a signal anti-jamming circuit; The remote transfer signal output terminal that described outstation is used for connecting upper computer module also is connected with a signal anti-jamming circuit.
The present invention has increased anti-jamming circuit at the power delivery of traditional supervisory system part and sensing, control signal hop, the ability of the power unit tolerance surge impact voltage of supervisory system is strengthened, avoid the device interior electron device to damage, behind the synchronous signal access arrangement, filtering high frequency interference, purify useful signal, make equipment operation, signal transmission and control reliable.
