Description

Technical Field

[0001] The present invention relates to a simulation debugging method and device for a wireless Lora sensor in a transformer substation, and in particular to a simulation development and testing technology for data messages of the wireless Lora sensor, belonging to a smart transformer substation technology. Background Art

[0002] "Q / GDW 12184-2021 Transmission and Transformation Equipment IoT Sensor Data Specification" is a standard proposed by the Equipment Management Department of State Grid Corporation of China. This standard regulates the message format used for sensor data transmission in the IoT perception layer of transmission and transformation equipment, and provides a reference for the standardization and unification of sensor and data message transmission. The standard clarifies the message format and requirements for business data, detection data, and alarm data. Sensors are distinguished by sensor SN, and each sensor data point has customized parameters and is different.

[0003] Wireless LoRa (Long Range) communication technology is a radio frequency technology based on spread spectrum communication. Due to its unique spread spectrum modulation method and efficient data transmission strategy, it can achieve long-distance communication transmission while maintaining low power consumption. It has the characteristics of low power consumption, long transmission distance, and strong anti-interference. At present, wireless LoRa sensors have been increasingly widely used in substations, such as wireless temperature and humidity sensors, wireless water immersion sensors, wireless air conditioning sensors, etc. These sensors use wireless LoRa communication technology to collect environmental data information in substations, laying a solid foundation for promoting the development of the power Internet of Things.

[0004] In order to realize the data transmission of wireless LoRa sensors in the substation, it is necessary to add a wireless LoRa access module in the gateway machine, and realize the data interaction between the gateway machine and the wireless LoRa sensor through the wireless LoRa access module; the wireless LoRa access module needs to encapsulate the downlink data from the wireless LoRa sensor, convert it into Mqtt message data or other network data, and then transmit it to the uplink platform. The encapsulated Mqtt message data structure is the encrypted data of the wireless LoRa sensor, and after decryption, it still complies with the "Q / GDW 12184-2021 Transmission and Substation Equipment Internet of Things Sensor Data Specification" standard.

[0005] Before connecting the wireless LoRa sensor to the gateway, the data message needs to be developed and tested first, and the downlink data from the wireless LoRa sensor needs to be obtained frequently and in large quantities; however, the wireless LoRa sensor usually has a reporting cycle and a processing cycle, and is usually in a dormant state for the rest of the time, so a batch of downlink data can only be obtained after a period of time, which greatly affects the development and testing efficiency; in order to increase the frequency and amount of downlink data reception, it is often necessary to directly operate the wireless LoRa sensor, but this increases the workload of development and testing; in addition, each type of wireless LoRa sensor needs to be developed and tested one by one, and it is difficult to gather all types of wireless LoRa sensors during the development and testing phase, which further increases the difficulty of development and testing. Summary of the invention

[0006] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a simulation debugging method and device for wireless LoRa sensors in a transformer substation room, so as to solve the problem of low efficiency in data message development and testing caused by dormancy of wireless LoRa sensors or incomplete types of wireless LoRa sensors.

[0007] Technical solution: To achieve the above purpose, the technical solution adopted by the present invention is: A simulation debugging method for a wireless Lora sensor in a transformer substation room comprises the following steps: creating a sensor device model for each type of wireless Lora sensor in a gateway machine, defining parameter information of the sensor model and parameter information of a model data point, wherein the parameter information of the sensor model includes a model unique code; configuring sensor data points in a configuration file of a wireless Lora message simulator, wherein the configuration information includes a sensor type serial number, a sensor type name and parameter information of the sensor data point; constructing a mapping relationship between the sensor type serial number and the model unique code, and then establishing a one-to-one correspondence between the model data point and the sensor data point, wherein the corresponding model data point and the sensor data point have the same data type, data length and data point parameter; in the wireless Lora message simulator, adding sensor devices and sensor data points by loading the sensor device model, using the added sensor devices and sensor data points to simulate and generate data point values ​​that meet the parameter information requirements of the sensor data points, and assembling the simulated data point values ​​into a message for transmission according to a set message transmission mode.

[0008] The present invention constructs a sensor device model and uses a wireless Lora message simulator to call the corresponding sensor device model to simulate sensor data points. The simulated data point values ​​can be obtained according to the needs of development and testing, thereby improving the efficiency of development and testing.

[0009] Specifically, the method of adding sensor devices and sensor data points in the wireless Lora message simulator is manual addition or remote loading; if it is manual addition, first select the sensor type serial number and / or sensor type name in the configuration file (usually displayed as the sensor name on the interface, the sensor name, sensor type serial number and sensor type name all point to the same object), then set the sensor SN code, and use the model data point corresponding to the sensor type serial number to add the sensor device and sensor data point; if it is remote loading, first remotely obtain the model unique code and sensor SN code of the sensor device model in the gateway machine, and then use the sensor type serial number and the parameter information of the sensor data point to add the sensor device and sensor data point according to the mapping relationship between the sensor type serial number and the model unique code, and set the sensor SN code.

[0010] Specifically, the wireless Lora message simulator assembles the simulated data point values ​​into messages for transmission in units of sensors or sensor data points according to the set message transmission mode.

[0011] Specifically, the message sending method is a binary data message or an Mqtt message; if it is a binary data message, the sensor SN number, data point parameters and data point values ​​are assembled into a binary data message; if it is an Mqtt message, the sensor SN number, data point parameters and data point values ​​are first assembled into a binary data message, and then the binary data message is Base64 encrypted and then encapsulated into an Mqtt message for the second time; both binary data messages and Mqtt messages are messages that comply with the "Q / GDW 12184-2021 Internet of Things Sensor Data Specification for Power Transmission and Transformation Equipment".

[0012] Specifically, after starting the wireless Lora message simulator, first load the configuration file of the sensor data point, and then summarize all sensor data points belonging to the same sensor type according to the sensor type serial number; in the process of adding sensor devices and sensor data points, first select the sensor type serial number and / or sensor type name, and then add the corresponding sensor data point according to the parameter information of the corresponding sensor device model.

[0013] Specifically, the parameter information of the model data point includes data type, data length, data parsing method and data point parameter; the parameter information of the sensor data point includes data point name, data point parameter, unit, data type, data length, value range, four remote types and associated data point parameter. It is necessary to keep the corresponding model data point and sensor data point with the same data type, data length, data parsing method and data point parameter.

[0014] Specifically, the four remote control types are remote signaling, remote measurement, remote control and remote adjustment.

[0015] Specifically, the wireless Lora message simulator triggers message sending in a periodic random manner or a manual triggering manner; if it is a periodic random manner, then the offset time of the periodic sending is set for each sensor data point at the initial startup of the wireless Lora message simulator, and the offset time of different sensor data points in each sending cycle is different, the message sending time of different sensor data points is different, or the message sending time of different sensors is different; if it is a manual triggering manner, then the sending interface of a certain sensor or sensor data point is manually selected, and the sensor data sending test is performed separately, which has strong mobility and is particularly suitable for the development and testing of a certain data point or sensor.

[0016] Specifically, when the wireless Lora message simulator receives a control message sent by the gateway, it parses the control message to obtain the corresponding sensor SN code, data point parameters and data point control value, and refreshes the data point value of the corresponding sensor in the wireless Lora message simulator according to the data point control value. At the same time, according to the associated data point parameters, it obtains the associated sensor data points, refreshes the associated data point values, and composes the sensor SN code, associated data point parameters and associated data point values ​​into a Lora response message as control feedback for reporting.

[0017] Specifically, the method comprises the following steps: Step 1. In the gateway, create a sensor device model for each type of wireless Lora sensor. Wireless Lora sensors of the same sensor type have the same list of sensor data points, and the parameter information of the same sensor data point of wireless Lora sensors of the same sensor type is consistent; the sensor device model includes two parts: sensor model and model data point. The parameter information of the sensor model includes model ID, model name and model unique code. The model unique code is a string identifier used to identify the sensor type, and its uniqueness is guaranteed in the gateway; the parameter information of the model data point includes model data point ID, model data point name, model ID, data type, data length, data parsing method and data point parameter; Step 2. In the simulation configuration module, configure the sensor data points. The configuration information includes the sensor type serial number, sensor type name, data point name, data point parameter, unit, data type, data length, value range, four remote types and associated data point parameters; each sensor type serial number corresponds to a sensor type; Step 3. In the configuration file of the sensor data point, add the mapping relationship between the sensor type serial number and the model unique code of the device model in the gateway, and then establish a one-to-one correspondence between the model data point and the sensor data point. The corresponding model data point and sensor data point have the same data type, data length, data parsing method and data point parameters. Step 4, start the wireless Lora message simulator, first load the configuration file of the sensor data point, then summarize all the sensor data points belonging to the same sensor type according to the sensor type serial number, and obtain the parameter information of the sensor data point, including the data point name, data point parameter, unit, data type, data length, data parsing method, value range, four remote types and related data point parameters; Step 5. In the wireless Lora message simulator, load the mapping relationship between the sensor type serial number in the sensor configuration file and the model unique code of the device model in the gateway; Step 6. In the wireless Lora message simulator, add sensor devices and sensor data points by loading sensor models and model data points: (1) Manual addition: Select the sensor type serial number loaded in Step 4, set the sensor SN code, and use the sensor model and model data point corresponding to the sensor type serial number to add the sensor device and sensor data point; (2) Remote loading: Remotely obtain the model unique code and sensor SN code of the sensor device model in the gateway machine, obtain the sensor type serial number in the configuration file of the sensor data point according to the mapping relationship loaded in Step 5, set the sensor SN code, and then use the sensor type serial number and the parameter information of the sensor data point to add the sensor device and sensor data point according to the mapping relationship between the sensor type serial number and the model unique code, and set the sensor SN code; Step 7, the sensor device and sensor data point in the wireless Lora message simulator are simulated to generate data point values ​​that meet the parameter information requirements of the sensor data point; Step 8. The wireless Lora message simulator assembles the simulated data point values ​​into messages for transmission in units of sensors or sensor data points according to the set message transmission mode. The message transmission mode is a binary data message or an Mqtt message. If it is a binary data message, the sensor SN number, data point parameters and data point values ​​are assembled into a binary data message. If it is an Mqtt message, the binary data message is encrypted with Base64 and then encapsulated into an Mqtt message. Step 9. The wireless Lora message simulator uses a periodic random method or a manual trigger method to trigger message sending. If it is a periodic random method, the offset time of the periodic sending is set for each sensor data point at the initial startup of the wireless Lora message simulator, and the offset time of different sensor data points in each sending cycle is different. If it is a manual trigger method, manually select the sending interface of a certain sensor or sensor data point, and perform the sensor data sending test separately.

[0018] Step 10. When the wireless Lora message simulator receives the control message sent by the gateway, it parses the control message to obtain the corresponding sensor SN code, data point parameters and data point control value, and refreshes the data point value of the corresponding sensor in the wireless Lora message simulator according to the data point control value. At the same time, according to the associated data point parameters, it obtains the associated sensor data point, refreshes the associated data point value, and composes the sensor SN code, associated data point parameters and associated data point value into a Lora response message as control feedback for reporting.

[0030] The message sending unit assembles the simulated data point values ​​into a message for sending according to a set message sending mode.

[0031] The present invention is described in detail below in conjunction with specific implementation steps.

[0032] Step 1: Create a sensor device model in the gateway A sensor device model library is set up in the gateway machine to store sensor device models; a sensor device model is created for each sensor type of wireless Lora sensor, wireless Lora sensors of the same sensor type have the same sensor data point list, and parameter information of the same sensor data point of wireless Lora sensors of the same sensor type is consistent.

[0034] Step 2. Create a configuration file for the sensor data point in the simulation configuration module According to the design requirements of each sensor type, write the configuration file of the sensor data point. The configuration information includes the sensor type serial number, sensor type name, data point name, data point parameter, unit, data type, data length, value range, four remote types (telesignaling, telemetering, remote control and remote adjustment) and related data point parameters; each sensor type serial number corresponds to a sensor type.

[0035] Step 3. Add the mapping relationship between the sensor type serial number and the model unique code in the configuration file In the configuration file of the sensor data point, add the mapping relationship between the sensor type serial number and the model unique code of the device model in the gateway machine, and then establish a one-to-one correspondence between the model data point and the sensor data point. The corresponding model data point and sensor data point have the same data type, data length, data parsing method and data point parameters.

[0036] Step 4. Start the wireless Lora message simulator After starting the wireless Lora message simulator, first load the configuration file of the sensor data point, then summarize all sensor data points belonging to the same sensor type according to the sensor type serial number, and obtain the parameter information of the sensor data point, including data point name, data point parameter, unit, data type, data length, data parsing method, value range, four remote types and associated data point parameters; the corresponding model data point and sensor data point have the same data type, data length, data parsing method and data point parameter.

[0037] Step 5: Load the mapping relationship between the sensor type serial number and the model unique code In the wireless Lora message simulator, first load the mapping relationship between the sensor type serial number in the sensor configuration file and the model unique code of the gateway internal device model, and then summarize all sensor data points belonging to the same sensor type according to the sensor type serial number.

[0038] Step 6. Set the adding and sending methods of sensor devices and sensor data points like Figure 1 As shown in the figure, in the wireless Lora message simulator, add sensor devices and sensor data points by loading sensor models and model data points. First, select the sensor type serial number and / or sensor type name, and then add the corresponding sensor data points according to the parameter information of the corresponding sensor device model: (1) Manual addition: Select the sensor type serial number loaded in Step 4, set the sensor SN code, and use the sensor model and model data points corresponding to the sensor type serial number to add sensor devices and sensor data points.

In the wireless Lora message simulator, add sensor devices and sensor data points by loading sensor models and model data points: (1) Manual addition: Select the sensor type serial number loaded in Step 4, set the sensor SN code, and use the sensor model and model data point corresponding to the sensor type serial number to add the sensor device and sensor data point; (2) Remote loading: Remotely obtain the model unique code and sensor SN code of the sensor device model in the gateway machine, obtain the sensor type serial number in the configuration file of the sensor data point according to the mapping relationship loaded in Step 5, set the sensor SN code, and then use the sensor type serial number and the parameter information of the sensor data point to add the sensor device and sensor data point according to the mapping relationship between the sensor type serial number and the model unique code, and set the sensor SN code; Step 7, the sensor device and sensor data point in the wireless Lora message simulator are simulated to generate data point values ​​that meet the parameter information requirements of the sensor data point; Step 8, the wireless Lora message simulator assembles the simulated data point values ​​into messages for transmission in units of sensors or sensor data points according to the set message transmission mode, and the message transmission mode is a binary data message or an Mqtt message; If it is a binary data message, the sensor SN number, data point parameter and data point value are assembled into a binary data message; if it is an Mqtt message, the binary data message is Base64 encrypted and then re-encapsulated into an Mqtt message; Step 9. The wireless Lora message simulator uses a periodic random method or a manual trigger method to trigger message sending. If it is a periodic random method, the offset time of periodic sending is set for each sensor data point at the initial startup of the wireless Lora message simulator, and the offset time of different sensor data points in each sending cycle is different. If it is a manual trigger method, manually select the sending interface of a certain sensor or sensor data point, and perform the sensor data sending test separately. Step 10. When the wireless Lora message simulator receives the control message sent by the gateway, it parses the control message to obtain the corresponding sensor SN code, data point parameters and data point control value, and refreshes the data point value of the corresponding sensor in the wireless Lora message simulator according to the data point control value. At the same time, according to the associated data point parameters, it obtains the associated sensor data point, refreshes the associated data point value, and composes the sensor SN code, associated data point parameters and associated data point value into a Lora response message as control feedback for reporting.
