Abstract
The invention discloses a natural gas well detection grounding prevention control system. the system comprises a probe, a laser sensor is arranged in the probe, and composed of a laser device, a driver and a sensor receiver, the sensor receiver is connected with a center control unit on a well through a cable, the center control unit is connected with the input end of a motor controller through a relay, and the output end of the motor controller is connected with a motor. According to the scheme, the problem that detection equipment touches the bottom of the well in the gas well detection process is reliably solved, and in addition, the system is simple in structure and convenient to operate and has the high practical value.
Description
Technical field
The present invention relates to a kind of control system, particularly relate to the detection anti-tactile end control system under a kind of natural gas well.
Background technology
Along with global energy is nervous, environmental requirement improves, and natural gas is subject to the welcome of each side as a kind of emerging clean energy resource.Every supporting also in development at full speed for natural gas, but because the special circumstances of natural gas, natural gas gas storage well is operated under very high atmospheric pressure state.Be 25MPa(gauge pressure according to SY/T6535 " well for storage of high pressure gas " regulation gas well inspection pressure).So test for this high-pressure bottle just become special inspection industry very important content.But because natural gas development is very fast so supporting inspection machine does not also have maturation.Existing solution does not consider that checkout gear touches the protection at the end substantially, or only controls with operator, has certain restricted.The invention solves the protection question of natural gas well checkout equipment close to shaft bottom.
Summary of the invention
Object of the present invention is just to provide a kind of natural gas well to detect control system of the anti-tactile end, to solve Problems existing in background technology.
For achieving the above object, the present invention is by the following technical solutions:
The present invention includes probe, laser sensor is provided with in probe, laser sensor is made up of laser instrument, driver and transducer receivers, transducer receivers by cable be arranged on aboveground central controller and be connected, central controller is connected with the input of electric machine controller by relay, and the output of electric machine controller is connected with motor.
It also comprises at least one controller for amplifying laser signal, and controller is arranged between central controller and sensing receiver.
The described controller for amplifying laser signal is one, and controller is arranged in probe.
It also comprises at least two controllers for amplifying laser signal, and a controller is arranged in probe, and another controller is located between probe and central controller.
Described laser instrument is semiconductor laser.
Adopt the present invention of such scheme reliably to solve in gas well checkout procedure, checkout equipment touches the problem in shaft bottom, and in addition, structure of the present invention is simple, and convenient operation, has very high practical value.
Accompanying drawing explanation
Fig. 1 is flow diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, the present invention includes probe, laser sensor is provided with in probe, laser sensor is made up of laser instrument, driver and transducer receivers, transducer receivers by cable be arranged on aboveground central controller and be connected, central controller is connected with the input of electric machine controller by relay, and the output of electric machine controller is connected with motor.
As improvement of the present invention: arrange a controller for amplifying laser signal between central controller and sensing receiver, controller is arranged in probe, compared with not arranging before control, after controller is arranged, effectively can ensure the authenticity of aboveground central controller Received signal strength; In order to the distance between Accurate Determining shaft bottom and probe, two controllers are also set between central controller and sensing receiver, three controllers, or more, can arrange a controller by probe, other controller is arranged between probe and central controller by distance.
Laser instrument is semiconductor laser, compared with other laser instrument, has that efficiency is high, volume is little, lightweight, structure simple, electric energy directly can be converted to laser energy, power conversion efficiency is high. be convenient to the advantage such as directly modulation, power saving.
Operating principle of the present invention is as follows: the laser instrument in laser sensor is to natural gas well bottom emitting laser pulse, partial pulse through reflecting is after transducer receivers and drive processes, pass to after being amplified by the controller be arranged in probe and be arranged on aboveground central controller, when central controller judges to draw natural gas well checkout equipment close to shaft bottom, relay is often left from normally closed becoming, and then by electric machine controller, motor is quit work, stop natural gas well checkout equipment to continue to advance to shaft bottom.
