Abstract
The utility model discloses a mining disaster remote control alarming cut-off device, which comprises a monitoring center station, signal transmission lines, monitoring substations and gas sensors. The monitoring center station is connected with a plurality of the monitoring substations distributed at different underground production places through the signal transmission lines; a series of mutually serially connected gas sensors are connected to signal input ends of the monitoring substations; and the serially connected gas sensors are continuously arranged on an excavation working surface. The mining disaster remote control alarming cut-off device is characterized in that a remote relay is serially connected onto each monitoring substation; an audible and visual alarm is connected to an output end of the remote relay; and the audible and visual alarm is arranged on the excavation working surface. When terrible accidents such as gas and the like happen at a certain place of a coal mine underground, each remote relay is closed and the audible and visual alarm sends alarm, thereby the device realizes rapidly informing working staffs at other places to rapidly evacuate from danger areas, effectively avoids casualty accidents and ensures safe production.
Description
Technical field:
The utility model relates to a kind of mining disaster remote control warning breaker device.
Background technology:
At present, along with the raising of Coal Production ability, the downhole production area enlarges gradually, and roadway distance is long, production link is many, operating location disperses, flow of personnel is big, operating environment is complicated.Particularly the fire damp accident happens occasionally, and has a strong impact on the safety in production in colliery, and miner's life security is caused very big harm.For the gas situation to getting working face detects monitoring, make the janitor's room staff in time understand the gas situation of each production site, down-hole, according to the pertinent regulations of national Coal Mine Safety Supervision Bureau, the coal gaseous mine must be installed gas and detect supervising device.Present gas detects supervising device and is made up of monitoring central station, signal transmssion line, outstation, firedamp sensor etc.Monitoring central station is arranged in the aboveground janitor's room, and monitoring central station is made of monitoring host computer, Network attachment, supply unit, printer, monitoring giant-screen.Monitoring central station is connected with some outstations that are distributed in different production sites, down-hole by signal transmssion line, and the signal input part of outstation has connected the row firedamp sensor of polyphone mutually, and the firedamp sensor of polyphone is arranged on getting working face continuously.When a certain getting working face place gas exceeding limit or when having an accident, the operator on duty will know accident conditions immediately, send signal by monitoring central station to the control substation, be transferred to the outstation that to control by holding wire, after the collection of substation process information, conversion, isolation, the processing, the device power supply (DPS) that cuts off this area prevents that accident from enlarging.In addition, adopt Advise By Wire and personnel to notify other compromised regional personnel to withdraw, but because the down-hole phone is provided with limited, and the line is busy and ring unanswered's phenomenon in normal appearance, there are problems such as efficient is low, unreliable again in personnel's notice, usually make other compromised regional personnel affect the best adversely and withdraw opportunity, cause casualty accident.
The utility model content:
The purpose of this utility model provides a kind of when serious accidents such as a certain place generation gas under the coal mine, the mining disaster remote control warning breaker device that energy is timely, other compromised regional personnel of vaild notice withdraw fast.
To achieve these goals, the utility model comprises: monitoring central station, signal transmssion line, outstation, firedamp sensor, monitoring central station is connected with some outstations that are distributed in different production sites, down-hole by signal transmssion line, the signal input part of outstation has connected the row firedamp sensor of polyphone mutually, the firedamp sensor of polyphone is arranged on getting working face continuously, it is to be serially connected with long-range relay on each outstation, the output of long-range relay has connected an audible-visual annunciator, and audible-visual annunciator is arranged on getting working face.
Like this, when serious accidents such as a certain place generation gas under the coal mine, the operator on duty will know accident conditions immediately, handle monitoring central station by the operator on duty and send signal to each control substation, control signal is transferred to the outstation that will control by holding wire, after the collection of each substation process information, conversion, isolation, the processing, the device power supply (DPS) that cuts off this area prevents that accident from enlarging.Each long-range relay closes, audible-visual annunciator are reported to the police, thereby realize that fast notification other places operating personnel withdraws the hazardous area rapidly, effectively avoid casualty accident, ensure safety in production.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a member connection structure schematic diagram of the present utility model.
Fig. 2 is the control principle schematic diagram of long-range relay.
The specific embodiment:
As seen from Figure 1, Figure 2, the utility model comprises: monitoring central station, signal transmssion line, outstation, firedamp sensor.Monitoring central station is arranged in the aboveground janitor's room, and monitoring central station is made of monitoring host computer, Network attachment, supply unit, printer, monitoring giant-screen.Monitoring central station is connected with some outstations that are distributed in different production sites, down-hole by signal transmssion line, the signal input part of outstation has connected the row firedamp sensor of polyphone mutually, the firedamp sensor of polyphone is arranged on getting working face continuously, on each outstation, be serially connected with long-range relay, the output of long-range relay has connected an audible-visual annunciator, and audible-visual annunciator is arranged on getting working face.Audible-visual annunciator can adopt the voice chip architecture, is arranged to the form of audio alert, is fit to people's hearing custom, improves the warning effect.
As shown in Figure 2, long-range relay adopts the pulse code control principle to constitute, and two control line double as driving powers need not additional power source during work.The controlled point of relay belongs to the control of some hairdo, and state keeps being finished state restoration after the dead electricity by internal circuit.Be provided with six toggle switchs in the electrical relaybox, outstation sends signal to relay, and each relay can independently select to be subjected to control relationship.Its six toggle switchs, preceding 4 effective controls that are used for setting No. 4 sensors, the 5th is used for setting often the opening of output contact/normally closed, and many relay unifications are driven by the pair of control line and realize multichannel control, and the switch of high-voltage relay is used for the selection of controlled sensor.On the pair of control line, can connect a plurality of relays and realize the distant early warning power operation in a plurality of places.The acousto-optic electric alarms based on pattern recognition be connected to long-range relay by detection, dispense with outer connecting power, with often the opening of one group of contact in the long-range electrical relaybox → normally closed, audible-visual annunciator is connected the back and is realized power alarm, in time reminds the staff to withdraw from the hazardous area.The working programme of remote alarms down techniques comprises: the transmission of the collection of information, transmission of Information, information processing, early warning signal, transmission, outage, warning.
