Description
Technical Field
The utility model discloses the structure belongs to the gas measurement field, realizes the detection function to terminal pipeline pressure, relates to a gas table structure for monitoring gas pipeline terminal pressure.
Background
At present, a pipe pressure monitoring scheme of a gas pipeline is basically concentrated on a front-end pipeline, and pipe pressures at the tail ends of a low-pressure pipeline and a gas transmission pipeline are not particularly concerned, so that part of gas users have poor gas using experience due to insufficient gas supply pressure; the gas company cannot master the actual gas supply effect of the pipe network.
The utility model discloses the structure has realized the collection and the monitoring to gas pipeline terminal pipe pressure, through the control analysis that lasts to relevant data, has solved past several problems. Due to the fact that the pipe pressure of the pipeline terminal is low, the abnormal gas consumption of a user can be found in time through collected pipe pressure data, and early warning can be given to the user with the trend of pipe pressure being low in advance; a gas company can acquire the terminal pipe pressure of each gas supply branch through a gas meter without additionally increasing pipe pressure monitoring equipment, so that the cost is saved and the popularization is easy; after the data reach certain scale, the gas company can form the detailed pipe pressure chart of whole gas supply network from the source end to the terminal according to relevant data, promotes self gas supply pipeline management level, makes things convenient for overall planning and maintenance.
SUMMERY OF THE UTILITY MODEL
To the not enough of existence among the prior art, the utility model provides a gas table structure for monitoring gas pipeline terminal pressure.
The utility model provides a gas table structure for monitoring gas pipeline terminal pressure, includes steel casing (1) on the base table, gas table intelligence main control board (2), base table external pressure sensor (3), steel casing (4) and base table internal pressure sensor (5) under the base table:

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The present solution is further illustrated in the following description with reference to the drawings and the detailed description, but is not to be construed as being limited thereto.
As shown in fig. 1, a gas meter structure for monitoring gas pipeline terminal pressure, includes steel casing 1 on the base meter, gas meter intelligence main control board 2, base meter external pressure sensor 3, steel casing 4 and base meter internal pressure sensor 5 under the base meter:
the intelligent main control panel 2 of the gas meter is arranged on the outer side of the upper steel shell 1 of the base meter, and the external pressure sensor 3 of the base meter and the internal pressure sensor 5 of the base meter are connected with the intelligent main control panel 2 of the gas meter.
The pressure sensor 5 in the base meter is fixed in a lower steel shell of the base meter through a plastic protective shell, and the base meter is led out of the base meter to the intelligent main control board 2 of the gas meter through a copper wiring terminal. The protective shell is used for protecting electronic devices related to the base surface pressure sensor 5 from being isolated from gas in the meter, so that the corrosion of substances such as water vapor, oil stains and the like in an actual gas environment to the electronic devices is avoided, and meanwhile, the pressure sensing surface of the base surface pressure sensor 5 is ensured to be in good contact with the gas in the meter. The base meter internal pressure sensor 5 is used for measuring the absolute pressure of the gas in the base meter, and the accuracy is +/-50 Pa.
And the external pressure sensor 3 of the base meter is arranged on the intelligent main control board 2 of the gas meter, and the cavity fixed by the main control board is well communicated with the external atmospheric environment. The external pressure sensor 3 of the base meter is used for measuring the absolute pressure of the atmosphere outside the base meter, and the precision is +/-50 Pa.
The working process is as follows:
the intelligent main control board 2 of gas table accessible gas table is through the pressure value of preset program regular collection base table external pressure sensor 3 and base table internal pressure sensor 5, calculates the difference between base table external pressure sensor 3 pressure value and base table internal pressure sensor 5 pressure value, reachs the pipeline pressure value, takes notes pipeline pressure value and uploads upper system.
