Description

Technical Field

[0001] The present invention relates to the technical field of power system automation and intelligentization, and in particular to a method and system for IED equipment to identify sensor manufacturers. Background Art

[0002] With the advancement of the intelligent construction of the State Grid, the access of SF6 sensors is crucial for substations. There are a large number of sensors used on site, and most of them use the MODBUS protocol for data transmission. However, the communication protocols of different manufacturers are different, and even in the same substation, sensors from different manufacturers may be used.

[0003] In the traditional access method, when deploying on-site, it is necessary to confirm the manufacturer and protocol of the sensor, and manually configure the IED according to the protocols of different manufacturers. The efficiency is extremely low and there is a possibility of errors. Most manufacturers can configure sensor access by configuring the meter through software, which greatly improves the work efficiency on-site. However, the essence of this method is still that technicians configure the access data manually. Different substations require different configurations, and when using sensors from multiple manufacturers, multiple configurations are required. The efficiency of on-site construction is low, and it is believed that errors may occur during the configuration process.

[0004] Therefore, how to provide an IED device that can automatically analyze manufacturer information based on key bytes in the data sent by the sensor and realize automatic configuration according to the built-in protocol is a problem that needs to be solved urgently. Summary of the invention

[0005] The embodiments of the present invention provide a method and system for IED device identification of sensor manufacturers to solve the problem of conversion and adaptation between the original protocol and the new protocol in the prior art. In order to have a basic understanding of some aspects of the disclosed embodiments, a simple summary is given below. This summary is not a general review, nor is it intended to identify key / important components or describe the scope of protection of these embodiments. Its only purpose is to present some concepts in a simple form as a preface to the detailed description that follows.

[0006] According to a first aspect of an embodiment of the present invention, a method for an IED device to identify a sensor manufacturer is provided.

[0007] In one embodiment, the method comprises: Read configuration information from IED devices; transforming configuration information according to types of the plurality of sensors, the configuration information including communication protocols of the plurality of sensors; Acquire a first target sensor address of a first target sensor among the multiple sensors; The IED device automatically sends instructions according to the first communication protocol of the target sensor; The first target sensor receives the command, parses it, and returns data based on the parsing result; The IED device determines whether the data returned by the first target sensor is normal: If the data received by the IED device does not contain an error code, the sensor model of the corresponding address connected is the first target sensor, and subsequent operation instructions for reading the sensor data corresponding to this address are sent and parsed according to the first communication protocol of the target sensor; If the data received by the IED device contains an error code, it continues to determine whether it is the Nth target sensor until the data received by the IED device does not contain an error code and the IED device identifies it correctly.

[0008] Based on the above solution, the step of automatically sending instructions by the IED device according to the first communication protocol of the target sensor specifically includes: S41: Setting the sending address to the first target sensor address; S42: Setting the first function code; S43: Setting the first register address of the data to be read; S44: Set the number of registers to be read to 1; S45: Automatically add CRC checksum according to the data.

[0009] On the basis of the above scheme, if the data received by the IED device contains an error code, the steps of continuing to determine whether it is the Nth target sensor, until the data received by the IED device does not contain an error code and the IED device recognizes the correct data, specifically include: S621: If the sensor sends a matching signal with an error code command to the IED device, it is further determined whether the returned abnormal code is "0x02". If the returned abnormal code is not "0x02" and the CRC check is wrong, it means that the communication is abnormal. The IED device automatically sends instructions according to the first communication protocol of the target sensor by repeating the steps; S622: If the abnormal code returned by the sensor is "0x02", it means that the register reading is abnormal, that is, the register with the address of the first register address is undefined, which means that the sensor with the corresponding address connected is not the first target sensor; S623: If the situation in step S622 is met, the instruction is automatically sent again according to the second communication protocol of the second target sensor.

[0010] On the basis of the above scheme, the step S623: if the situation of step S622 is met, the step of automatically sending instructions according to the second communication protocol of the second target sensor again specifically includes: ①Set the sending address to the second target sensor address; ②Set the second function code; ③Set the second register address of the data to be read; ④Set the number of registers to be read to 1; ⑤Automatically add CRC check code according to data.

[0011] On the basis of the above scheme, if the data received by the IED device contains an error code, the step of continuing to determine whether it is the Nth target sensor, until the data received by the IED device does not contain an error code and the IED device recognizes the correct step, further includes: S624: receiving data returned by the sensor; if the data received by the IED device does not contain an error code, the sensor model of the corresponding address connected at this time is the second target sensor, and subsequent operation instructions for reading the sensor data corresponding to this address are sent and parsed according to the second communication protocol; S625: If the sensor returns a command with an error code, it is further determined whether the returned exception code is "0x02". If the returned exception code is not "0x02" and the CRC check is wrong, it means that the communication is abnormal, and the command is automatically sent again according to the second communication protocol of the second target sensor; S626: If the exception code returned by the sensor is "0x02", it means that the register reading is abnormal, that is, the register with the address of the second register address is undefined, which means that the connected sensor with the corresponding address is not the second target sensor.

[0012] On the basis of the above solution, the step S627: if the situation of step S626 is met, the step of automatically sending the instruction again according to the third communication protocol of the third target sensor specifically includes: ①Set the sending address to the third target sensor address; ②Set the third function code; ③Set the third register address of the data to be read; ④Set the number of registers to be read to 1; ⑤Automatically add CRC check code according to data.

[0013] On the basis of the above scheme, if the data received by the IED device contains an error code, the step of continuing to determine whether it is the Nth target sensor, until the data received by the IED device does not contain an error code and the IED device recognizes the correct step, further includes: S627: If the situation in step S626 is met, automatically sending instructions again according to the third communication protocol of the third target sensor; S628: receiving data returned by the sensor; if the data received by the IED device does not contain an error code, the sensor model of the corresponding address connected at this time is the third target sensor, and subsequent operation instructions for reading the sensor data corresponding to this address are sent and parsed according to the third communication protocol; S629: If an error code or a CRC check error is received, it indicates that a communication abnormality occurs, and the command is automatically sent again according to the third communication protocol of the third target sensor.

[0014] According to a second aspect of an embodiment of the present invention, a system for an IED device to identify a sensor manufacturer is provided.

[0015] In one embodiment, a conversion system comprises: A reading module is used to read configuration information from an IED device; A configuration module, used to transform configuration information according to types of the multiple sensors, the configuration information including communication protocols of the multiple sensors; An address module, used for acquiring a first target sensor address of a first target sensor among the multiple sensors; An instruction module, used for automatically sending instructions from the IED device according to the first communication protocol of the target sensor; The parsing module is used to receive the instruction from the first target sensor, parse it, and return data according to the parsing result; The judgment module is used for the IED device to judge whether the data returned by the first target sensor is normal: if the data received by the IED device does not contain an error code, the sensor model of the connected corresponding address is the first target sensor, and the subsequent operation instructions for reading the sensor data corresponding to this address are sent and parsed according to the first communication protocol of the target sensor; if the data received by the IED device contains an error code, it continues to judge whether it is the Nth target sensor until the data received by the IED device does not contain an error code and the IED device recognizes it correctly.

[0018] The technical solution provided by the embodiment of the present invention may have the following beneficial effects: The IED device proposed in the present invention can identify devices from different manufacturers by screening different key registers, and perform corresponding data analysis according to the manufacturer's communication protocol embedded in the device in advance. When the sensor is connected to the system, the IED automatically screens the key registers and corresponds to sensors from different manufacturers. At the same time, by parsing the error code returned by the sensor, if the data returned by the instruction sent this time is an exception code of 0x02, it is considered that the sent instruction cannot correspond to the corresponding sensor; if it is not an exception code of 0x02, it is considered that the communication is abnormal, and the query instruction is automatically resent to achieve automatic analysis of the abnormal state. In addition, through the built-in different sensor protocols, automatic data analysis is achieved to obtain information such as gas pressure, density, temperature, etc. in the current gas chamber; the workload of on-site manual configuration can be greatly reduced, the possibility of errors in manual configuration can be reduced, and the degree of automation of on-site data collection can be improved.

[0028] Figure 1 An embodiment of a method for an IED device to identify a sensor manufacturer according to the present invention is shown.

[0029] In this optional embodiment, the method for an IED device to identify a sensor manufacturer comprises the following steps: S1: Reading configuration information about the IED device from the IED device; S2: transforming configuration information according to types of the multiple sensors, where the configuration information includes communication protocols of the multiple sensors; S3: Obtaining an address of a first target sensor among the multiple sensors; S4: The IED device automatically sends instructions according to the first communication protocol of the target sensor; ①Set the sending address to the first target sensor address; ②Set the first function code; ③Set the first register address of the data to be read; ④Set the number of registers to be read to 1; ⑤Automatically add CRC check code according to data; S5: The first target sensor receives the instruction, parses it, and returns data according to the parsing result; S6: The IED device determines whether to receive the data returned by the first target sensor: There are two cases: If the data received by the IED device does not contain an error code, the sensor model of the corresponding address connected at this time is the first target sensor, and subsequent operation instructions for reading the sensor data corresponding to this address are sent and parsed according to the first communication protocol of the target sensor; If the data received by the IED device contains an error code, the type of sensor is further determined, including: (1) If the sensor sends a code signal with the command "0x83" to the IED device, it is further determined whether the returned abnormal code is "0x02". If the returned abnormal code is not "0x02" and the CRC check is wrong, it means that the communication is abnormal, and step S4 is repeated; (2) If the exception code returned by the sensor is "0x02", it means that the register reading is abnormal, that is, the register with the address of the first register address is undefined, which means that the sensor with the corresponding address connected is not the first target sensor; (3) If the condition (2) is met, the second target sensor automatically sends the following command again according to the second communication protocol: ①Set the sending address to the second target sensor address; ②Set the second function code; ③Set the second register address of the data to be read; ④Set the number of registers to be read to 1; ⑤Automatically add CRC check code according to data.

[0030] (4) Receive the data returned by the sensor. If the data received by the IED device does not contain an error code, then the sensor model of the corresponding address connected at this time is the second target sensor, and the subsequent operation instructions for reading the sensor data corresponding to this address are sent and parsed according to the second communication protocol; (5) If the sensor returns a command with a function code of "0x83", further determine whether the returned exception code is "0x02". If the returned exception code is not "0x02" and the CRC check is wrong, it means that the communication is abnormal, and repeat (3); (6) If the exception code returned by the sensor is "0x02", it means that the register reading is abnormal, that is, the register with the address of the second register address is undefined, which means that the sensor with the corresponding address connected is not the second target sensor; (7) If the situation in (6) is met, the command is automatically sent again according to the third communication protocol of the third target sensor: ①Set the sending address to the third target sensor address; ②Set the third function code; ③Set the third register address of the data to be read; ④Set the number of registers to be read to 1; ⑤Automatically add CRC check code according to data.

[0031] (8) Receive the data returned by the sensor. If the data received by the IED device does not contain an error code, then the sensor model of the corresponding address connected at this time is the third target sensor, and the subsequent operation instructions for reading the sensor data corresponding to this address are sent and parsed according to the third communication protocol; (9) If the function code "0x84" is received or the CRC check error occurs, it means that the communication is abnormal. Repeat (7).

[0032] In the method provided by the present application, different manufacturers use different communication protocols and registers. The manufacturer information can be obtained by determining the unique register of the manufacturer and analyzing it. And the built-in communication protocol is automatically adapted. At the same time, the system analyzes the received sensor abnormality code. When the received abnormality code is analyzed as a register error, the instruction can be resent according to other protocols; when a CRC check error is received, it is considered that the communication process is abnormal and needs to be re-read, and the original read instruction is resent to prevent the reading error caused by the communication abnormality. The present invention solves the problem of recognition error caused by communication error. By identifying the abnormal code of the sensor return data, it can be determined whether it is an error code generated by the read register error; if the returned abnormal code is 0x02, it is regarded as a read register error, and the instruction to read other models of sensors is sent. If the returned abnormal code is not 0x02 and the CRC check error is, it is regarded as a communication error, and the read instruction is automatically resent. The communication protocols used by SF6 sensors from different manufacturers are different. By logically identifying different key bytes, the manufacturer of the sensor can be distinguished, thereby determining the communication protocol to be used, which can greatly improve the accuracy of system analysis.

[0033] like Figure 2 As shown, the present invention provides a specific implementation scheme of a method for IED device to identify sensor manufacturers. The following takes the access to three sensor communication protocols of GDT-20, WDS530 and ZMJ1-Y to automatically distinguish devices as an example: (1) IED configures MODBUS communication protocol and all communication protocols of required sensors; (2) Obtain the address of the required sensor; (3) The IED first automatically sends instructions according to the GDT-20 communication protocol: ①Set the sending address to the sensor address; ②Set the function code to 0x03; ③Set the register address of the required read data to 0x0100; ④Set the number of registers to be read to 1; ⑤Automatically add CRC check code according to data.

[0034] (3) At this point, the sensor receives the command and parses it; (4) Receive the data returned by the sensor. If the data received by the IED device does not contain an error code, then the sensor model of the corresponding address connected at this time is GDT-20. Subsequent operation instructions for reading the sensor data corresponding to this address are sent and parsed according to the GDT-20 protocol; (5) If the sensor returns a command with a function code of 0x83, further determine whether the returned exception code is 0x02. If the returned exception code is not 0x02 or the CRC check is wrong, it means that the communication is abnormal, and repeat (3); (6) If the exception code returned by the sensor is 0x02, it means that the register reading is abnormal, that is, the register with address 0x0100 is undefined, which means that the sensor with the corresponding address connected is not GDT-20; (7) If the situation in (6) is met, the command is automatically sent again according to the communication protocol of WDS530: ①Set the function code to 0x03; ②Set the register address of the required read data to 0x6600; ③Set the number of registers to be read to 1; ④Automatically add CRC check code according to the data.

[0035] (8) Receive the data returned by the sensor. If the data received by the IED device does not contain an error code, then the sensor model of the corresponding address connected at this time is WDS530. Subsequent operation instructions for reading the sensor data corresponding to this address are sent and parsed according to the WDS530 protocol; (9) If the sensor returns a command with a function code of 0x84, further determine whether the returned exception code is 0x02. If the returned exception code is not 0x02 or the CRC check is wrong, it means that the communication is abnormal, and repeat (7); (10) If the exception code returned by the sensor is 0x02, it means that the register reading is abnormal, that is, the register with address 0x0100 is undefined, which means that the sensor with the corresponding address connected is not WDS530; (11) If the situation in (10) is met, the command is automatically sent again according to the communication protocol of ZMJ1-Y: ①Set the function code to 0x04; ②Set the register address of the required read data to 0x1000; ③Set the number of registers to be read to 1; ④Automatically add CRC check code according to the data.

[0036] (12) Receive the data returned by the sensor. If the data received by the IED device does not contain an error code, then the sensor model of the corresponding address connected at this time is ZMJ1-Y. Subsequent operation instructions for reading the sensor data corresponding to this address are sent and parsed according to the ZMJ1-Y protocol; (13) If the function code 0x83 is received or the CRC check error occurs, it indicates that the communication is abnormal. Repeat (11).

[0037] The above 0x83 and 0x84 are both abnormal function codes. In actual application, there are many abnormal function codes. In this embodiment, only 0x83 and 0x84 are used for exemplary description, and are not limited to 0x83 and 0x84.

[0038] 0x02 is an exception code. In actual application, there are many exception codes. In this embodiment, only 0x02 is used for exemplary description, and it is not limited to 0x02.
