Description
Technical field
The utility model relates to a kind of circuit, particularly relates to a kind of circuit for mine safety supervisory control system.
Background technology
At present, Shanghai is used to praise the KJ92N type safety monitoring system of Li Co., Ltd's production, join KJ94N-F Monitor Sub-Station of Less, because feed sensor is stuck in by outside electric control cable, operation principle whether has electricity by leakage field monitoring cable, and then signal is uploaded to Monitor Sub-Station of Less → ground monitoring center, signal stabilization is poor, current collector equipment disturbs, and reliability is about 80%.
The operating voltage needed because of downhole production is upgraded to 1140V use shielded type cable (without there being leakage field) from 660V, the feed sensor making producer supporting lost efficacy, electric feed signal can not be reflected, not meeting 7.7.4 money in national AQ 1029-2007 standard (is the whether power-off of monitoring controlled device gas exceeding limit, controlled switch load side must arrange feed sensor) requirement, therefore electric feed signal is uploaded and must be carried out innovation transformation.
Summary of the invention
In order to make up the deficiencies in the prior art, solving shielded type cable without there being leakage field, supporting feed sensor being lost efficacy, can not electric feed signal be reflected, provide a kind of intelligent switch to pass safety monitoring electric feed signal.
The technical scheme in the invention for solving the technical problem is:
Intelligent switch passes safety monitoring electric feed signal, primarily of GJC4/40 methane transducer, KJ94N-F type monitoring station, KDW92B type is mining uninterrupted power supply, KBZ flame-proof type vacuum feed switch operating state contact K1 and KBZ flame-proof type vacuum feed switch methane monitor contact K2 forms, its annexation is: feed back transfer interface the 1st passage of KJ94N-F type monitoring station meets KBZ flame-proof type vacuum feed switch operating state contact K1, KBZ flame-proof type vacuum feed switch methane monitor contact K2 connects the mining uninterrupted power supply of KDW92B type built-in control port the 4th passage, KDW92B type is mining, and uninterrupted power supply is powered to KJ94N-F type monitoring station, KJ94N-F type monitoring station simulation flow control 1 passage connects GJC4/40 methane transducer.
The built-in control port of KDW92B type is mining uninterrupted power supply meets the methane monitor contact K2 of KBZ flame-proof type vacuum feed switch, when GJC4/40 methane transducer monitoring gas exceeding limit or transducer and line fault time perform gas electric shutting, the switch working state contact K1 of KBZ flame-proof type vacuum feed switch changes (often opening the normally closed or normally closed change of change often to open), directly security monitoring electric feed signal is transferred to KJ94N-F type monitoring station.
Power by 660V or 36V → KDW92B type is mining uninterrupted power supply powers → KJ94N-F type monitoring station → GJC4/40 methane transducer.
Monitor signal performs power-off by the methane monitor contact K2 of GJC4/40 methane transducer → KJ94N-F type monitoring station → KDW92B type is mining uninterrupted power supply → KBZ flame-proof type vacuum feed switch.
Feed is by the K1 → KJ94N-F type monitoring station → ground monitoring center, switch working state contact of KBZ flame-proof type vacuum feed switch.
In the utility model circuit diagram, eliminate coal mine safety monitoring system feed sensor, (feed sensor is stuck in by outside electric control cable, operation principle whether has electricity by leakage field monitoring cable, then signal is uploaded to Monitor Sub-Station of Less → ground monitoring center, signal stabilization is poor, current collector equipment disturbs, reliability is about 80%), use the idle contact direct transmission security monitoring electric feed signal of intelligent switch reflection operating state, signal stabilization is good, not current collector equipment interference, reliability, more than 98%, in use there will not be misoperation phenomenon.
The beneficial effects of the utility model are:
1, the utility model eliminates coal mine safety monitoring system feed sensor, the feed passback of KJ94N-F type monitoring station directly connects on the idle contact of KBZ flame-proof type vacuum feed switch operating state, direct transmission security monitoring electric feed signal, on the binding post of the empty node of direct connecting valve, signal stabilization is good, not current collector equipment interference, reliability, more than 98%, there will not be misoperation phenomenon.
2, the utility model saves human and material resources, improves the environment that operating efficiency optimizes underground equipment, more ensure that safety in production, improve equipment effectiveness.

Fig. 2 is circuit diagram before the utility model transformation.
Embodiment
In Fig. 1, intelligent switch passes safety monitoring electric feed signal, primarily of GJC4/40 methane transducer, KJ94N-F type monitoring station, KDW92B type is mining uninterrupted power supply, KBZ flame-proof type vacuum feed switch operating state contact K1 and KBZ flame-proof type vacuum feed switch methane monitor contact K2 forms, its annexation is: feed back transfer interface the 1st passage of KJ94N-F type monitoring station meets KBZ flame-proof type vacuum feed switch operating state contact K1, KBZ flame-proof type vacuum feed switch methane monitor contact K2 connects the mining uninterrupted power supply of KDW92B type built-in control port the 4th passage, KDW92B type is mining, and uninterrupted power supply is powered to KJ94N-F type monitoring station, KJ94N-F type monitoring station simulation flow control 1 passage connects GJC4/40 methane transducer.
