Description
The cable inflator telemetering device is mainly used in the remote measurement to telecommunication cable inflator duty and output gaseous mass parameter.
Existing inflator to the telecommunication cable inflation all needs manually on duty, because the inflator noise is big, can not man-machine same chamber, and when abnormality appears in machine, be difficult in time finding and processing, so easily form obstacle.Moreover each telecommunications branch office all is provided with gas-filling station, also is furnished with the duty personnel with regard to corresponding.The main cause that has above-mentioned phenomenon is can not centralized control to each gas-filling station, and can not central controlled reason be that duty and output gaseous mass parameter to inflator can not take remote measurement the shortcoming long-term existence that the cable pressurization quality is not high to personnel are wasted.
The purpose of this utility model is a kind of device that can take remote measurement in real time to cable inflator duty and its output gaseous mass parameter of development,, and realize by some microcomputer Centralized Monitorings because but the enforcement of this device makes with the gas-filling station of each telecommunications branch office of city unmanned again.
The utility model is at least by forming one of in compressor accumulated running time statistical organization, compressor operating temperature testing organization, gaseous tension testing agency, gas humidity testing agency, the gas flow testing agency.Compressor accumulated running time statistical organization is by motor M, normally opened contact J1, relay J, and normally opened contact J2 forms.Motor M is connected on the circuit of compressor, and motor output shaft band one cam is connected to a normally opened contact J1 near cam, and the contact of J1 connects power supply one end, and another contact is succeeded electrical equipment J coil one end, another termination power other end of coil.The contact ground connection of the contact J2 of relay J, another contact connects an input end of switch acquisition plate.The output terminal of the output terminal of the output terminal of the output terminal of compressor operating temperature testing organization, gaseous tension testing agency, gas humidity testing agency, gas flow testing agency is all received respectively on the input end of analog to digital converter, the monitoring computer of the output termination branch office gas-filling station of analog to digital converter.Motor M is whenever revolved and is turned around, and the cam on the motor just makes the J1 closure once, the J energising, and J2 also closure once just exports a pulse signal and adds up to computing machine on J2.After this compressor accumulative total was worked certain hour, computing machine just sent this compressor silence signal, makes it be in inspecting state.The compressor operating temperature testing organization is made up of temperature sensor, operational amplifier A 1.Temperature sensor is affixed on the electric machine casing of compressor, the input end of the output termination amplifier A1 of temperature sensor, an input end of the output termination analog to digital converter of amplifier A1.Gaseous tension testing agency is made up of pressure transducer, operational amplifier A 2, pressure transducer is installed in the bypass of inflator delivery gauge, the input end of the output termination amplifier A2 of pressure transducer, an input end of the output termination analog to digital converter of amplifier A2.Gas humidity testing agency is made up of humidity sensor, operational amplifier A 3.Humidity sensor is installed in the inflator export pipeline, the input end of the output termination amplifier A3 of humidity sensor, an input end of the output termination analog to digital converter of amplifier A3.Gas flow testing agency is made up of flow sensor, operational amplifier A 4.Flow sensor is installed in being close in the road of inflator export pipeline, the input end of the output termination amplifier A4 of flow sensor, an input end of the output termination analog to digital converter of amplifier A4.The monitoring computer of the output termination branch office gas-filling station of analog to digital converter, the monitoring computer of each branch office's gas-filling station is networked again in the central monitoring computing machine, form remote measurement, monitor network, as long as establish people's work that gets final product the real-time telemetry control and treatment with cable pressurization station, city on duty at the central monitoring computing machine.Five testing agencies of the present utility model can assort in a device simultaneously, also can only be equipped with one of them or several arbitrarily.
The real time status of the accumulative total working time of the remote telemetry cable inflator of the utility model energy, the working temperature of compressor, its output gas pressure, gas flow, gas humidity is to the greatest extent to have created condition with the remote concentrated remote measurement control of each gas-filling station realization of city.Can save a lot of manpowers, especially can guarantee the operate as normal of inflator, improve gaseous mass, reducing obstacle provides reliable assurance.The corresponding general disturbance rate of communication that also makes reduces greatly.
