As shown in fig. 2, the first pressure transmitter 15 is electrically connected to the secondary metering device and communicates unidirectionally, the first differential pressure transmitter 16 is electrically connected with the secondary metering instrument and is in one-way communication with the secondary metering instrument, the first temperature sensor 6 is electrically connected with the secondary metering instrument and is in one-way communication with the secondary metering instrument, the second pressure transmitter 17 is electrically connected with the controller and is in one-way communication, the second differential pressure transmitter 18 is electrically connected with the controller and is in one-way communication, the second temperature sensor 7 is electrically connected with the controller and is in one-way communication, the secondary metering device is electrically connected with the controller and is in one-way communication, the controller is electrically connected with the electric control valve 8 and is in one-way communication with the electric control valve, the controller is electrically connected with the first communication device and is in one-way communication with the first communication device, the monitoring server is electrically connected with a second communication device and is in two-way communication with the second communication device, and the second communication device is in wired connection with the first communication device and is in two-way communication with the first communication device.

The controller is a single chip microcomputer, and the metering instrument management and control cabinet, the secondary metering instrument, the valve, the orifice plate, the temperature sensor, the electric control valve, the pressure guide pipe, the pressure transmitter, the differential pressure transmitter, the server, the communication device and the corresponding communication connection technology are not repeated in the prior art.

The conception of the application is as follows:

the pressure-pressure difference pressure guide pipe and the pipeline of the heat supply valve are additionally provided with a set of pressure, pressure difference and temperature sensors, the set of sensors are represented as a second pressure sensor, a second pressure difference sensor and a second temperature sensor in the figure, the sensors are not provided with a display screen and a keyboard, the output signals of the sensors and the measured value are in a fixed corresponding relation, the output signals cannot be changed or reset, and the signals output by the sensors are all digital signals.

The output signals of the set of sensors are all input into front-end equipment, the digital signals are pre-processed and then uploaded to a monitoring platform of an upper computer, namely a monitoring server, an artificial intelligence technology is adopted, a set of parameters are calculated through the platform, a set of tables corresponding to the original metering data of the product meter are established on the platform one by one, data in the tables and the uploaded data of an original product meter system have a fixed corresponding relation, intermediate data which cannot be listed in the corresponding tables can be obtained correspondingly by adopting a linear interpolation method. Once the upper computer platform software finds that the corresponding relation between the upper computer platform software and the upper computer platform software changes, the situation that the user privately changes the field state can be accurately determined, and the hot-stealing behavior is suspected. Or a failure of the metering system in the field.

Because the working mode and the output data type of the second set of pressure difference, pressure and temperature sensor are different from the working mode and the output data type of the original first set of differential pressure transmitter-integrating instrument system, when a user maliciously adjusts a valve on a pressure guide pipe, maliciously distorts the current situation of the pressure difference transmitter on site, randomly alters any one sensor therein, or resets the initialization parameter of the integrating instrument, the corresponding relation of the data in the two fixed corresponding relation tables on the upper computer platform must change, and the user cannot tamper the two types of signals into the same corresponding relation, so the scheme can find any alteration behavior of the user on site in time, or find the fault of the metering system on site. Once abnormal, the upper computer monitoring platform can immediately start alarm and carry out permanent record with time marks, and informs the supervisory personnel to process in time.
