Abstract
The utility model provides a monitored control system in pit, belongs to colliery additional equipment field, including power, sensor, and control substation, transmission line, still include the filter, the filter install on transmission line, the filter install between control substation and sensor perhaps the filter install at the power and between by the power supply unit, have and can effectively avoid monitored control system in pit and produced owing to disturb gathering and the characteristics of the false phenomenon of transmitting data.
Description
Technical field
The utility model belongs to ancillary service field, colliery, particularly a kind of underground monitoring system.
Background technology
In the production operation in colliery, in order to ensure the production safety of down-hole, and monitoring downhole production situation, under normal circumstances, can arrange monitoring system in down-hole, described monitoring system comprises power supply, sensor, outstation, transmission line; Power supply is arranged in power supply box usually, for monitoring system provides electric power energy; Sensor comprises downhole temperature, monitoring gas content, humidity, the detection of pressure etc.; Outstation is by the relevant information of sensor collection, stores and processes, then is transferred to aboveground monitoring system, differentiates that whether the working condition of down-hole is normal, for the production decision in colliery provides information with other monitoring systems after integrating; In existing underground work occasion, have a large amount of power-equipments simultaneously, as winch etc., in order to improve the service behaviour of these equipment, these equipment start to adopt converter technique in a large number, frequency converter is installed, because existing monitoring system is also transmitted by electric wave, the electric wave that these frequency conversion equipments produce can produce interference to the transmission of monitoring system, cause the Asymmetry information etc. that the information of sensor collection in monitoring system and outstation obtain, namely distortion, causes error to monitoring and decision-making.
Summary of the invention
For the problems referred to above that existing coal mine underground monitoring system exists, the utility model proposes a kind of underground monitoring system, it is characterized in that: comprise power supply, sensor, outstation, transmission line; It is characterized in that: also comprise filter; Described filter is arranged on transmission line; Described filter is arranged on filter between outstation and sensor or described and is arranged on power supply and is powered between equipment; Described filter is capacitor; Described capacitor is electrolytic capacitor.
Beneficial effect
The beneficial effects of the utility model are, can effectively avoid underground monitoring system due to disturbed and produce and gather and transmission data false phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
1. power supply, 2. wiring terminal, 3. transmission line, 4. filter, 5. outstation, 6. sensor.
Detailed description of the invention
In order to the technical solution of the utility model is described, now further illustrate detailed description of the invention of the present utility model by reference to the accompanying drawings, as Fig. 1, in this example, select electrochemical capacitor as filter 4, under the state that monitoring system and down-hole frequency conversion equipment are normally opened, adopt connected mode and unit type that the industry is general, power supply 1, outstation 5, transmission line 3, sensor 6 are connected, and start normal operating conditions, oscillograph and universal meter is adopted first to detect power supply 1, outstation 5, transmission line 3, the voltage of sensor 6 and waveform, after finding waveform instability, through the calculating to electronic component used, then electronic component model is accurately drawn, withstand voltage, after capacity, the parameter of the electrochemical capacitor drawn after the sensor power power supply 1 calculated again after adding electrochemical capacitor in outstation 5 adds calculating, according to the parameter of the Selecting parameter electrochemical capacitor calculated, and electrochemical capacitor is installed in monitoring system, observe 48 hours, in full reportedly normally defeated, just complete enforcement of the present utility model, because various parameter has on-the-spot test, the conclusion drawn after stable, so good reliability.
