Abstract
The utility model relates to a measurement and control platform of a super-high-pressure gas system, which comprises a pressure sensor used for measuring the pressure of the super-high-pressure gas system, and a super-high-pressure electromagnetic valve used for controlling the switching of the working state of the super-high-pressure gas system. The pressure sensor is connected with a PC unit through an AD sampling unit. The PC unit is installed with LabVIEW-based measurement and control software. The PC unit is connected with the super-high-pressure electromagnetic valve so as to control the super-high-pressure electromagnetic valve through the output of an IO drive unit. The AD sampling unit, the super-high-pressure electromagnetic valve and the IO drive unit are arranged in a testing room. The PC unit is arranged in a master control chamber. The PC unit is connected with the AD sampling unit and the IO drive unit through an RS485 bus. Due to the adoption of the measurement and control platform, the super-high-pressure gas system can be measured and controlled remotely.
Description
Technical field
The utility model relates to measurement, the control system of ultra high pressure gas system.
Background technology
At present, for the ultra high pressure gas system, realize monitoring and control by fax tensimeter and simple mechanical switch, be suitable for field control.But because the characteristic of ultra high pressure gas system, on-the-spot closely operation has certain danger, for personal safety, needs the scheme of a kind of remote measurement, control ultra high pressure gas system badly.
The utility model content
The purpose of this utility model provides a kind of monitoring platform of ultra high pressure gas system, in order to solve the large problem of closely control danger in the prior art.
For achieving the above object, scheme of the present utility model is: a kind of monitoring platform of ultra high pressure gas system, comprise for the pressure transducer of measuring ultra high pressure gas system pressure, and be used for the extra-high voltage magnet valve that control ultra high pressure gas system duty is switched; Described pressure transducer connects PC by the AD sampling apparatus, and PC is by the described extra-high voltage magnet valve of IO drive unit output control linkage; During described AD sampling apparatus, extra-high voltage magnet valve and IO drive unit were arranged between test, described PC was arranged in the master-control room, and described PC connects described AD sampling apparatus and IO drive unit by the RS485 bus.
The monitoring platform of ultra high pressure gas system of the present utility model, measurement, opertaing device in connecting between PC in the master-control room and test with the RS485 bus, operating personnel can realize observing and controlling to gas system by the operation PC in master-control room, realized remote measurement, control ultra high pressure gas system.And installation can realize the several data processing capacity, as read, prints current or historical data based on the TT﹠C software of LabVIEW on the PC; Memory function to the turn-on data of solenoid valve; The whole power down function of solenoid valve when withdrawing from software, overpressure alarm function etc.
Description of drawings
Fig. 1 is structure principle chart of the present utility model;
Fig. 2 is LabVIEW operation interface schematic diagram of the present utility model.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
The monitoring platform of a kind of ultra high pressure gas system as shown in Figure 1 comprises for the pressure transducer of measuring the input of ultra high pressure gas system, output pressure, is used for the extra-high voltage magnet valve that control ultra high pressure gas system duty is switched; Pressure transducer connects PC by the AD sampling apparatus, and PC is by IO drive unit output control linkage extra-high voltage magnet valve; During AD sampling apparatus, extra-high voltage magnet valve and IO drive unit were arranged between test, PC was arranged in the master-control room, and PC connects described AD sampling apparatus and IO drive unit by the RS485 bus.
The gas system working pressure is 55MPa.By RS485 Long-distance Control extra-high voltage magnet valve, data transmission distance is large, and maximum can reach 1219m.
Be the operation interface based on the LabVIEW TT﹠C software that PC is installed such as Fig. 2, when different solenoid valve buttons was pressed in click, the ultra high pressure gas system had different working conditions.Input pressure and output pressure show the force value of ultra high pressure gas system in real time.The input test production code member if should numbering exist, then shows the solenoid valve 1 unlatching situation (1 accumulation opening time of solenoid valve and solenoid valve 1 accumulation opening times) of this numbering product in the lower right corner, main interface; If numbering does not exist, then 1 accumulation opening time of solenoid valve and solenoid valve 1 accumulation opening times all are shown as 0." preservation " button is used for preserving the pressure curve of current viewing area." read " button and be used for reading the historical pressures curve.After having read historical air feed curve, must click " resetting " and just can get back to main interface." printing " button is used for printing curve and the corresponding detecting information that shows.Click " test " button, click again " solenoid valve 1 " button, observable real-time pressure curve.When pressing " solenoid valve 3 " button, if output pressure is lower than setup pressure value, solenoid valve 3 can autoshutdown.
Claims (1)
1. the monitoring platform of a ultra high pressure gas system is characterized in that, comprises for the pressure transducer of measuring ultra high pressure gas system pressure, is used for the extra-high voltage magnet valve that control ultra high pressure gas system duty is switched; Described pressure transducer connects PC by the AD sampling apparatus, and the TT﹠C software based on LabVIEW is installed on the PC, and PC is by the described extra-high voltage magnet valve of IO drive unit output control linkage; During described AD sampling apparatus, extra-high voltage magnet valve and IO drive unit were arranged between test, described PC was arranged in the master-control room, and described PC connects described AD sampling apparatus and IO drive unit by the RS485 bus.
