Description
Technical field
The utility model relates to a kind of mining electric equipment, and is concrete, relates to a kind of long-range on off controller of mining electric equipment.
Background technology
Safety of coal mines is the most important thing in the Coal Production always, has a lot of electric equipments to need remote operation in the actual production, a long way off an equipment is controlled, and its reliability directly influences the safe coefficient of system.Current domestic electric equipment realizes that remote operation substantially all is to use simple three-wire type guide loop control unit, because three control lines distances are all long, is easy to the situation that short circuit occurs or open circuit, error starting or mistakenly stop car at this moment will occur.In addition, some advanced electric equipments have used guide's controlling schemes comparatively reliably, but its volume is excessive, and flexibility is bad, and cost is higher.
The utility model content
The purpose of this utility model is at above shortcomings in the existing electric equipment remote operation process, a kind of realization single line Long-distance Control is provided, unfailing performance is good, volume is little, interface flexible, and can satisfy the mining electric equipment guide controller that safety of coal mines requires again.
The technical solution of the utility model is: a kind of mining electric equipment guide controller, comprise guide's control module and far-end control circuit, guide's control module is connected with far-end control circuit by guide's control line, described guide's control line is set to one, far-end control circuit one end is connected with guide's control line, other end ground connection; Described far-end control circuit is that a diode D1 connects mutually with a resistance R 1 and a normally closed button K2, and the two ends of resistance R 1 also are parallel with one and often open button K1;
Preferably, the described control module of leading comprises single-chip microcomputer, the square wave generation circuit, inverse signal testing circuit and the voltage isolation module that are connected with single-chip microcomputer respectively, and the relay output circuit that is connected with the voltage isolation module;
Preferably, described square wave generation circuit is connected with far-end control circuit by guide's control line respectively with the inverse signal testing circuit;
Preferably, described far-end control circuit is provided with test side A and test side B, and test side A is connected with guide's control line, test side B ground connection.
The beneficial effects of the utility model are: (1) wiring is simple, can realize guide's control by a lead, has saved cable.(2) reliability height, starting device need click stop button K2 earlier, presses start button K1 ability starting device again, has prevented staff's misoperation; Simultaneously, because the structure of far-end control circuit, when short-circuit conditions appears in control line, can not starting device.(3) all circuit sealing of the utility model elder generation guide module is in a plastic casing, and volume is small and exquisite, interface flexible.
Description of drawings
Fig. 1 is the circuit diagram of the utility model specific embodiment far-end control circuit;
Fig. 2 is the electrical schematic diagram of the utility model specific embodiment guide control module.
Embodiment
Specific embodiment of the utility model as illustrated in fig. 1 and 2: a kind of mining electric equipment guide controller, comprise guide's control module and far-end control circuit, guide's control module is connected with far-end control circuit by guide's control line.Guide's control module comprises single-chip microcomputer, the square wave generation circuit, inverse signal testing circuit and the voltage isolation module that are connected with single-chip microcomputer respectively, and the relay output circuit that is connected with the voltage isolation module; Square wave generation circuit is connected with far-end control circuit by guide's control line respectively with the inverse signal testing circuit.Far-end control circuit is provided with test side A and test side B, and test side A is connected with guide's control line, test side B ground connection; To be a diode D1 connect with resistance R 1 and a normally closed button K2 of one 30 ohm far-end control circuit mutually, and the two ends of resistance R 1 also are parallel with one and often open button K1.
Operation principle: the high and low level that provides alternate by the single-chip microcomputer output CON1 in guide's control module, CON2, the high and low level of alternate transforms the generation square wave voltage signal by square wave generation circuit and passes to guide's control line, provides voltage signal by guide's control line to far-end control circuit again.When the CON1 of single-chip microcomputer output high level, during the CON2 output low level,, press K1 or K2 any one or two buttons by output low level behind the square wave generation circuit, electric equipment does not does not start or stop, and has avoided misoperation.When the CON1 of single-chip microcomputer output low level, during CON2 output high level, by exporting high level behind the square wave generation circuit, the detected voltage signal of single-chip microcomputer is the voltage at resistance R 1 and diode D1 two ends; When pressing normally closed button K2, normally closed button K2 opens, and far-end control circuit disconnects, the resistance infinity, and the detected voltage signal of single-chip microcomputer is an open circuit voltage; Press to press in 5 seconds behind the normally closed button K2 and often open button K1, at this moment, normally closed button K2 closure is often opened button K1 closure, resistance R 1 short circuit, and the detected voltage signal of single-chip microcomputer is the voltage at diode D1 two ends.
When starting electric equipment, press normally closed button K2 earlier, and in 5 seconds, press and often open button K1, at this moment, the detected voltage signal of single-chip microcomputer is for pressing the voltage that is changed when often opening button K1 in 5 seconds after pressing normally closed button K2 from pressing normally closed button K2, at this moment, and single-chip microcomputer output OUT1 output low level, by the actuating of relay in the voltage isolation module controls relay output circuit, thereby start electric equipment.
When stopping electric equipment, press normally closed button K2, normally closed button K2 opens, the detected voltage signal of single-chip microcomputer is an open circuit voltage, at this moment, and the single-chip microcomputer output low level, by the actuating of relay in the voltage isolation module controls relay output circuit, thereby stop electric equipment.
