Abstract
A hump wind pressure monitoring system comprises a plurality of wind pressure detection sensors arranged on a pipeline, a programmable logic controller (PLC) and a monitoring computer. The wind pressure detection sensors are connected with the input end of the PLC via a pressure transmitter and an analog quantity input module, and the output end of the PLC is connected with an alarm repositor, an acousto-optic alarm and the monitoring computer respectively via a switch input module, a switch output module and a communication module; the wind pressure detection sensors are arranged between the air supply pipeline valves of a pneumatic decelerator and an electro-pneumatic switch machine and the pneumatic decelerator and the electro-pneumatic switch machine, and expansion conditions are reserved. By using the sensors to acquire the wind pressure data information at each part of the pipeline, and using the PLC to gather the data to the monitoring computer, the man-machine interaction is finished, the full-time interval, all-weather and whole process management is realized, the 24-hour on-line rolling type monitoring and alarm is carried out, a real-time dynamic management is possible, the safe operation of a hump system can be guaranteed better and the worker labor intensity is reduced.
Description
Technical field
The utility model relates to a kind of system for monitoring hump yard pneumatic retarder and electropneumatic point machine air-supply pipeline blast.
Background technology
Hump yard generally adopts pneumatic car retarder and electropneumatic point machine, require very high to its safe and reliable row, its air feed system requires trunk line to require to be annular configuration, but hump air supply system blast in the past detects and just draws an arm to the duty room place in the duty room place nearby at air supply system, and tensimeter simple displaying hump air supply system blast is set.Because hump air supply system pipeline is long and speed reduction unit and electropneumatic point machine are the instantaneous wind of using of discontinuity, it can not be in time and accurately reflects each situation with wind devices, and valve is more in the air supply system, each is provided with valve before with wind devices, so in actual applications, owing to behind on-site maintenance or other artificial origin's valve-off, the hidden danger that has an accident just being arranged.And it does not have the early warning and alarming function.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the above problems, to adopt advanced at present digital-to-analogue acquisition technique and automatic control technology, a kind of hump yard blast supervisory system is provided, the air feed situation of real-time multipoint acquisition air supply system.
The purpose of this utility model is achieved through the following technical solutions: hump blast supervisory system, it is characterized in that: comprise that several are installed in blast detecting sensor, PLC controller and supervisory control comuter on the pipeline, described blast detecting sensor is connected with the input end of PLC controller by pressure unit, analog input module, and the output terminal of PLC controller is connected with ann reset device, audible-visual annunciator, supervisory control comuter respectively via input module switch, switching output module, communication module.
The beneficial effects of the utility model: the utility model adopts said structure, the blast detecting sensor is installed in each position on pipeline as required, the blast detecting sensor is located between the air supply line valve of pneumatic retarder and electropneumatic point machine and its, and reserves expansion condition.Gather the wind pressure data information at each position of pipeline by sensor, and data communication device is crossed the PLC controller be aggregated into supervisory control comuter, finishing man-machine interaction is by graphical demonstration pipeline multiple spot blast situation, have the early warning of blast low pressure, cross low and sudden change (rate of change) sound and light of alarm.Can also be for each monitoring point arrange different pipe network pressure tap bounds and rate of change alarming value, in case out-of-limit, screen prompt warnings at different levels.Realize all the period of time, round-the-clock, Whole Course Management, online tumbling-type monitored, reports to the police in 24 hours, made instant dynamic management become possibility.Can better guarantee hump system security of operation, alleviate labor strength.
Description of drawings
Fig. 1 is circuit block diagram of the present utility model.
Fig. 2 is the circuit theory diagrams of the utility model embodiment.
Embodiment
Hump blast supervisory system, its structured flowchart as shown in Figure 1, comprise that several are installed in blast detecting sensor 1, PLC controller 4 and supervisory control comuter 9 on the pipeline, blast detecting sensor 1 is connected with the input end of PLC controller 4 by pressure unit 2, analog input module 3, the output terminal of PLC controller 4 is connected with supervisory control comuter 9 via communication module 6, the output terminal of PLC controller 4 is connected with audible-visual annunciator 8 via switching output module 5, and the output terminal of PLC controller 4 is connected with ann reset device 10 via input module switch 7.
