Description
Technical field
The present invention relates to oil, colliery and geologic prospecting drilling engineering deviational survey field, relate in particular to a kind of system that improves solenoid valve efficient and reliability.
Background technique
[0002] along with the development of oil, colliery and geologic prospecting drilling well, need monitor in real time, make wireless drilling inclinometers be widely used the down-hole equipment attitude.Wireless drilling inclinometers converts the various parameters in down-hole into the mud-pulse signal through electromagnetic valve component and uploads to ground.
At present, when electromagnetic valve component carried out underground work, the battery pack that needs the down-hole was that capacitance group provides energy, and capacitance group provides voltage and current for electromagnetic valve device again.The adhesive of electromagnetic valve component needs the load on the very big electric current ability pull-up armature, but the maintenance attracting state of electromagnetic valve component but only needs smaller voltage and current.Present electromagnetic valve component is made up of MCU control unit, unlatching adhesive control unit, maintenance/disconnection control unit, electromagnetic valve component mostly; The unlatching adhesive of electromagnetic valve component realizes through the capacitance group discharge; Detect electromagnetic valve component whether adhesive puts in place through program and be difficult to the break-make of real-time control capacitance group voltage, thereby in use cause capacitor discharge too much to cause the solenoid valve capacity usage ratio low.The down-hole Environmental Conditions is abominable, and the easily influenced program that causes of the reliability of program running gets into endless loop or deadlock, and this moment, capacitance voltage can be reduced to below the battery voltage rating, influenced the proper functioning of other equipment, and life-span of battery pack is also had considerable influence.
Summary of the invention
In order to overcome the deficiency that capacity usage ratio is low, reliability is low of existing electromagnetic valve component, the utility model provides a kind of system that improves solenoid valve efficient and reliability.
The utility model solves the technological scheme that its technical problem adopted: be made up of maintenance/disconnection control unit, MCU control unit, unlatching adhesive control unit, electromagnetic valve component, it is characterized in that having increased filter processing unit and capacitance voltage protected location.Filter processing unit is made up of filtering wave by prolonging time circuit, negative impulse generation circuit, edge generation circuit, buffer circuit; The capacitance voltage protected location is made up of resistance and capacitances in series; The break-make of capacitance group voltage and capacitance voltage protected location all are made up of hardware circuit, can realize response fast and control automatically.After the electromagnetic valve component adhesive is stable; Electromagnetic valve component enameled cable coil produces a sharp pulse feedback signal, after handling through filter processing unit, breaks off the capacitance group power voltage supply; At this moment low voltage, the maintenance of little electric current/disconnection driver element can make electromagnetic valve component keep attracting state; When electromagnetic valve component does not have timely adhesive, the capacitance voltage protected location can break off by control capacitance group voltage, to prevent the descended voltage rating of as many as battery of capacitance group voltage.
The beneficial effect of the utility model is to have realized a kind of system that improves solenoid valve efficient and reliability.
