Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

An embodiment of the present invention provides a method for detecting interconnection and interoperability of oil and gas equipment. As shown in FIG. 1 , the method includes the following steps 101 to 103:

Step 101. Obtain the parameters of the device under test measured by the standard detection system. The standard detection system includes the device under test and the standard device. The standard device follows the standard protocol, and the device under test follows the manufacturer's protocol.

Wherein, the standard protocol is a standard WIA-Pa protocol or ZigBee protocol or the like. The WIA-Pa technical standard is a wireless industry standard independently developed by China. It has the characteristics of strong anti-interference ability, low power consumption, strong real-time communication, and high reliability. It has already had a large number of application practices in the digital construction of the petroleum industry. As a key technology of wireless communication, this technology has been written into the construction specification of the oil and gas production Internet of Things system in the communication technology standard of the oil and gas industry.

The manufacturer's agreement is the agreement followed by the oil and gas equipment determined by the manufacturer. Since some manufacturers will customize the agreement on the basis of the standard agreement, the manufacturer's agreement may be the same or different from the standard agreement.

As shown in Figure 2, it is an architecture diagram of a standard detection system. Referring to Fig. 2, the test computer can realize the connection with RTU through Ethernet, local serial port, RS485 port or network port etc., RTU is connected with acquisition equipment, RTU can be single well RTU or cluster well type RTU (shown simultaneously in Fig. 2 In addition to the two RTUs, the standard detection system can only include one of the RTUs). Figure 2 exemplarily shows acquisition equipment such as temperature transmitters, pressure transmitters, dynamometers, electric parameter modules, and flow automatic controllers. In addition to the above equipment, other acquisition equipment used in oil and gas production can also be used. Devices are tested for interoperability.

All devices in the standard detection system are ad hoc networks with the following characteristics:

①. The slave station address allocation mode of the gateway is set to static allocation;

②. The group number of each device participating in the detection is configured as 1;

③. The RTU enables simulated drilling. In this mode, both the RTU and the dynamometer can upload the simulated current diagram and simulated power diagram;

④. The upload period of power diagram and current diagram is set to 30 minutes;

⑤, the pressure gauge number is 0-2;

⑥, the number of the thermometer is 0;

⑦. The test computer is equipped with test software, which can display information such as production data, simulation data, and instrument status data collected by various instruments.

The standard testing system includes the equipment to be tested, the standard equipment and the test computer. When the equipment to be tested is RTU, the standard equipment is the collection equipment. The architecture of the standard detection system used can be seen in Figure 3. The RTU to be tested can be connected to multiple acquisition devices, and the acquisition device sends standard data packets, and parses the standard data packets to obtain analysis parameters and RTU device parameters. In the embodiment of the present invention, when the device under test is an RTU, the analysis parameter and the RTU device parameter are used as the device parameter under test.

Among them, the data in the standard data packet is written by the acquisition device according to the field order and standard field values defined by the standard protocol, and sent to the RTU by the acquisition device. That is to say, the standard protocol defines the order of the fields. For example, when the acquisition device is a temperature sensor, the first field it writes is the current temperature, the second field is the average temperature, and the third field is the acquisition device. model, the acquisition device writes standard data packets in the above order, and the standard protocol defines the field value and byte quantity of each field. For example, the temperature field value ranges from 000 to 100 and the byte quantity is 3, then When the current temperature is detected, select the field value corresponding to the temperature and write it into the first three bytes of the standard data packet. In this way, the field value of each field is written in order, and the number of bytes of the written field value also conforms to the number specified in the standard protocol, and a standard data packet is obtained.

When the RTU receives the standard data packet, it parses the standard data packet according to the parsing method corresponding to the vendor protocol adopted by itself. Generally, the parsing method defines the number of bytes in each field. For example, for a section of the standard data packet 030105, the vendor agreement defines that it contains 3 fields, the first field occupies 3 bytes, the second field occupies 1 byte, and the third field occupies 2 bytes, then RTU parses The standard data packet gets parsed parameter 030/1/05.

After getting the analysis parameters, the RTU will store the analysis parameters in the register, and then pack the analysis parameters in the register and its own RTU device parameters into a new data packet and send it to the test computer for the test computer to confirm according to the parameters to be tested in the data packet Whether the RTU adopts the standard protocol.

It should be noted that the RTU generally uses the Modbus protocol to pack data packets, and the test computer can accurately analyze the Modbus protocol data packets. Therefore, it can be ruled out that the interconnection confirmation error caused by the computer analyzing the wrong data packet sent by the RTU can be ruled out.

RTU device parameters include local real-time data, local alarm data, local historical data, device upgrade data and configuration data. Equipment upgrade data includes local upgrade data, point-to-point upgrade data and remote upgrade data. For RTU equipment parameters, standard parameters are also defined. When the comparison of RTU equipment parameters fails, it is also considered that the RTU equipment does not adopt the standard protocol to ensure the accuracy of interconnection and interoperability verification.

When the device to be tested in the standard detection system is a collection device, the standard device is an RTU, and the standard detection system shown in Figure 4 can be used, and the RTU is connected to the collection device to be tested. Obtaining the parameters of the device under test measured by the standard detection system may be performed as follows: obtaining the analysis parameters obtained by analyzing the collected data packets according to the standard data analysis method defined by the standard protocol as the parameters of the device under test.

Among them, the standard data analysis method defines the number of bytes corresponding to each field value arranged in a fixed order; the data in the collection data packet is written by the collection device according to the manufacturer's protocol followed by the collection device, and sent to the RTU by the collection device.

That is, the collection data packet is written by the collection device according to the manufacturer's agreement. For example, it may occupy 2 bytes according to the current temperature in the first field, 1 byte in the average temperature in the second field, and 1 byte in the third field device type It takes 3 bytes to write. The standard data analysis method defines the analysis method required by the standard protocol. For example, the first field average temperature occupies 3 bytes, the second field current temperature occupies 1 byte, and the third field device type occupies 2 characters. Section, for a set of data 030105, the acquisition device considers that 03 is the current temperature, 0 is the average temperature, and 105 is the device type; when the standard RTU is analyzed according to the standard data analysis method, it is considered that 030 is the average temperature and 1 is the current temperature , 05 is the device type, so in step 102, when the above parameters obtained by RTU analysis are compared with the standard parameters, the comparison will fail, and it is confirmed that the acquisition device does not use the standard protocol, and the device using the standard protocol cannot be parsed correctly The parameters of the collection equipment are not interoperable with other oil and gas equipment using standard protocols.

The parameters written into the standard data packet or the collection data packet by the collection device include measurement parameters and collection device parameters.

The measurement parameter is a parameter obtained when the acquisition device performs its function, for example, the measurement parameter of the temperature sensor is temperature, the measurement parameter of the humidity sensor is humidity, and the measurement parameter of the wind speed sensor is wind speed.

The collected device parameters include configuration parameters, device upgrade parameters and alarm parameters. Configuration parameters include basic configuration parameters, point-to-point configuration parameters and remote configuration parameters. Point-to-point configuration parameters include transmit power, data rate, PanID, timing parameters, well station type, well station number, RTU existence identification, RTU master-slave identification, RTU type, Group number/number and type of fluid.

In addition, some transmission data may be generated in the RTU and the acquisition device, which can be used as the parameters of the device under test.

It should be noted that for different RTUs or different collection devices, the RTU device parameters and collection device parameters may be different from the above-mentioned RTU device parameters and collection device parameters. The device itself decides.

Step 102, comparing the parameters of the device under test with the preset standard parameters.

In the embodiment of the present invention, a standard parameter is predefined, which is a value or a range of values. For example, when the device to be tested is a temperature sensor, the measurement parameter is temperature, and the corresponding standard parameter is 10 to 40. If the parameter of the device to be tested is 20, it is confirmed that the comparison is passed; if the parameter of the device under test is 50, it is confirmed that the comparison is not passed.

Following the example in step 101, if the device to be tested is an RTU, the parsing parameters of the standard data packets parsed by it are 030, 1, 05, and the corresponding standard parameters are 000~100, 01, 1~6, then the parsing parameters are the same as the standard The comparison of parameters fails; if the corresponding standard parameters are 000~100, 1, 01~06, the comparison passes.

Step 103, if the comparison is passed, it is determined that the manufacturer's protocol followed by the device under test is a standard protocol, which has interconnection and interoperability.

If the comparison is passed, it indicates that the manufacturer's protocol is also a standard protocol, and devices that conform to the standard protocol can correctly read the corresponding data of other devices, which has interconnection and interoperability.

In the embodiment of the present invention, the standard detection system including the standard equipment and the equipment to be tested is used to collect and upload the parameters of the equipment to be tested, and compare the parameters of the equipment to be tested with the standard parameters. If the comparison is passed, it is considered that the equipment to be tested follows The manufacturer's agreement is also a standard agreement. Since the equipment that follows the standard agreement can be interconnected, it is confirmed that the equipment under test has interconnection and interoperability. Compared with the inspection of technical parameters of each equipment in the prior art, which is difficult to implement due to the large number of technical parameters, the embodiment of the present invention adopts the method of mutual verification between the equipment to be tested and the standard equipment, and only one set of standard equipment is required.
