Description
Technical field
The present invention relates to a kind of intelligent display control system for coal mine deep hole drilling vehicle.
Background technology
Owing to coal seam existing a large amount of gas, for ensureing production safety, method frequently with coal mine deep hole drilling vehicle release gas avoids harm, coal mine deep hole drilling vehicle is that a kind of track-type is visited water, visited the rig of gas, is to integrate mechanical, electrical, the down-hole visual plant of liquid, sensing, information technology.Existing coal mine deep hole drilling vehicle is mainly by the process manually carrying out corresponding situation, lack a kind of integrated management, effectively control, the intelligent display control system of information display function, so security performance is the highest, reliability is relatively low, can not process emergency case timely and effectively.
Summary of the invention
The invention reside in and overcome above-mentioned deficiency, it is provided that a kind of security performance is high, and reliability is higher, the intelligent display control system for coal mine deep hole drilling vehicle that can process emergency case in time.
The object of the present invention is achieved like this:
A kind of intelligent display control system for coal mine deep hole drilling vehicle is made up of firedamp sensor, pressure transducer, displacement transducer, pulse codr, industrial control unit (ICU), industrial LCD, electromagnetic valve, electromagnetic proportional valve and oil cylinder and hydraulic motor.
Intelligent display control system for coal mine deep hole drilling vehicle of the present invention, drilling rod height displacement parameter, drill pipe angle displacement parameter, gas density and the system pressure value that the real-time display controller of described industrial LCD gathers.
Intelligent display control system for coal mine deep hole drilling vehicle of the present invention, when described gas density is more than the first setting value, exports the rotating speed controlling electromagnetic proportional valve reduction drilling rod, slow operation by the PWM of controller；When described gas density is more than the second setting value, stop drilling rod operation.
Intelligent display control system for coal mine deep hole drilling vehicle of the present invention, described system pressure value is too high, gas density too high situation time industrial LCD can point out the source of trouble, and be attended by audible alarm.
Compared with prior art, the invention has the beneficial effects as follows:
Intelligent display control system for coal mine deep hole drilling vehicle of the present invention can be with real-time monitoring system force value, drilling rod height displacement parameter, drill pipe angle displacement parameter and gas density；Drilling rod can be automatically moved into the position of needs according to assigned altitute displacement parameter and given angle displacement parameter；Rod rotation speed can be reduced according to the gas density monitored or operation is crept in stopping；Breaking down or during gas exceeding limit situation, the source of trouble can be pointed out and warn with sound.

Detailed description of the invention
As it is shown in figure 1, intelligent display control system for coal mine deep hole drilling vehicle of the present invention is made up of firedamp sensor, pressure transducer, displacement transducer, pulse codr, industrial control unit (ICU), industrial LCD, electromagnetic valve, electromagnetic proportional valve and oil cylinder and hydraulic motor.
As shown in Figure 2, Fig. 2 is industrial LCD content schematic diagram, described industrial LCD is connected with industrial control unit (ICU) by RS232 interface, alarm when industrial LCD shows current system pressure value, gas density, drilling rod height displacement parameter, drill pipe angle displacement parameter in real time and breaks down, and show instantaneous operating conditions and to important history parameters record.When occurring that system pressure value is too high, gas density too high situation time industrial LCD can point out the source of trouble, and be attended by audible alarm.
nullAs shown in Figure 3，Fig. 3 is that drilling rod is automatically positioned schematic diagram，After determining given drilling rod height displacement parameter and angle displacement parameter，The current angular displacement parameter that encoder measures judges compared with given angle displacement parameter，If current angular displacement parameter is inconsistent with given angle displacement parameter，So industrial control unit (ICU) carries out PWM output，Controlling electromagnetic proportional valve drives hydraulic motor to drive chassis to carry out spinning movement，Chassis spinning movement is stopped when the angle of chassis rotation is consistent with given angle parameter，Then determine that the present level displacement parameter that displacement transducer measures is the most consistent with assigned altitute displacement parameter，If present level displacement parameter is inconsistent with assigned altitute displacement parameter，Industrial control unit (ICU) carries out PWM output，Control electromagnetic valve hoist cylinder，Cylinder action is stopped when present level displacement parameter is consistent with assigned altitute displacement parameter.
As shown in Figure 4, Fig. 4 is that gas monitor controls schematic diagram, by the judgement to gas density, can be adjusted the rotating speed of drilling rod: when gas density is normal, and given rotating speed operation pressed by drilling rod；When i.e. gas density is more than the first setting value when there is a small amount of spray orifice, exported the rotating speed controlling electromagnetic valve reduction drilling rod, slow operation by the PWM of controller；When a large amount of spray orifice occurs, when i.e. gas density is more than the second setting value, stop drilling rod operation.
