Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of can the import and export pipeline to monitor simultaneously, and can carry out the gaseous-pressure monitor of wireless remote signal transmission.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of gaseous-pressure monitor, include circuit board, and the LCD display that electrically connects with circuit board, central processing system and pressure transducer, circuit board is provided with the power input that electrically connects with external power source, it is characterized in that: described pressure transducer includes inlet pressure sensor and outlet pressure sensor, the gaseous-pressure monitor also includes the CDMA device, the CDMA device comprises CDMA communicator and CDMA antenna, the input end and the central processing system of CDMA communicator electrically connect, and the input end of the output terminal of CDMA communicator and CDMA antenna electrically connects.
Adopt technique scheme, described inlet pressure sensor and outlet pressure sensor are installed respectively in the import of gas pipeline and outlet, so the gaseous-pressure monitor can carry out real-time monitoring to the import of gas pipeline and the pressure of outlet simultaneously, thereby has improved for pipeline pressure monitoring accuracy and integrity.In addition, being provided with of CDMA device can send to outside receiving end by Wireless transmission mode with the pressure signal that is monitored, thereby realized promptness, and the worker that need not to check meter goes to make a copy of to every family, greatly reduce workload and labour cost multi-user monitoring.
Of the present utility modelly further be set to: also be connected with standby power supply and isolating switch on the described circuit board, standby power supply and circuit board electrically connect, and power input is in series on isolating switch and the circuit board.
Adopt technique scheme, when fortuitous events such as outage occurring, standby power supply has then played real-time substitution effect, and guaranteeing also can operate as normal under the situation that does not have outside input power supply.Simultaneously, the setting of isolating switch has guaranteed when outside input power source abnormality, might cause under the situation that the gaseous-pressure monitor damages, and the isolating switch automatic cutout, thus guaranteed the safety of gaseous-pressure monitor.
Of the present utility modelly further be set to: described circuit board is provided with the temperature measurer of the temperature that monitors the working environment, and the output terminal and the central processing system of temperature measurer electrically connect.
Adopt technique scheme, temperature measurer the real-time monitoring that has realized temperature under the working environment is set, and in time control some abominable temperature variation by artificial means, and then guaranteed that the gaseous-pressure monitor can not cause that humidity changes because of the change of temperature in the environment, thereby making to produce on the gaseous-pressure monitor coagulates frost, and the situation that has influence on gaseous-pressure monitor operate as normal occurs.
Of the present utility modelly further be set to again: also be provided with the storer that electrically connects with central processing system on the described circuit board.
Adopt technique scheme, the setting of storer can be carried out real time record and stores the data that got by the central processing system place, convenient after during data query as a reference.
Below in conjunction with accompanying drawing the utility model is further described:
