As such, three breaker mechanisms, three or six knife-switch mechanisms 110 are included for each high voltage switch 100. Further, a plurality of types of sensors are provided for each of the knife switch mechanisms 110 to detect different states of the knife switch. For example, the gas sensor 111, the angle sensor 112, the attitude sensor 112, and the like. The gas sensor 111 is used for detecting various parameters such as the concentration, temperature and humidity of the ambient gas where the disconnecting link mechanism 110 is located; the angle sensor 112 is used for detecting the angle of the disconnecting link mechanism 110; the attitude sensor 112 is used to detect the operating attitude of the disconnecting link mechanism 110 and the like. Meanwhile, each high-voltage switch 100 is in communication connection with a control cubicle, a monitoring device 200 is arranged in the control cubicle, and the monitoring device 200 monitors the state of the knife switch mechanism 110 in the high-voltage switch 100 by acquiring sensing data detected by each sensor and fusing the sensing data.

Further, each of the knife switch mechanisms 110 of the high-voltage switch 100 of the present embodiment is provided with a mechanism box, a plurality of sensors for detecting the state of the knife switch mechanism 110 are provided in the mechanism box, and each of the sensors is a wireless sensor, and a first wireless communication unit (not shown in fig. 1) is provided to transmit the detected sensing data in a wireless communication manner. In order to upload the sensing data to the monitoring apparatus 200 for processing, a second wireless communication unit 220 establishing a wireless communication connection with the first wireless communication unit, and a processor 210 are provided in the monitoring apparatus 200. Within the processor 210 is running a software program comprising a service module 211, a sensor management module 212 and at least one data application module 213.

Further, the processor 210 can control the at least one data application module 213 to send the preset configuration parameters to the service module 211 and control the service module 211 to send to the sensor management module 212 based on the registered downlink command theme; thereafter, the configuration parameters it receives are sent to the plurality of sensors via the wireless communication connection by controlling the sensor management module 212. The plurality of sensors can configure the wireless communication parameters after receiving the configuration parameters, and upload the sensing data detected by the sensors to the sensor management module 212 via the wireless communication connection established by the first wireless communication unit and the second wireless communication unit 220 according to the wireless communication parameters; the processor 210 also controls the sensor management module 212 to transmit the sensing data to the service module 211 by means of the registered uplink data topic; and the control service module 211 transmits target sensing data corresponding to the application function of at least one data application module 213 in the received sensing data to the corresponding data application module 213 for processing, and the processing result is obtained to monitor the knife switch mechanism 110 in the high voltage switch 100.

Further, in this embodiment, the sensor management module 212 determines the target sensor corresponding to the configuration parameter according to the device ID in the configuration parameter, and issues the configuration parameter to the target sensor through the wireless communication connection.

Specifically, the issued configuration parameters at least include a working mode, a device ID and a communication channel, where the device ID is used to characterize the set sensor type, the working mode characterizes a wireless communication mode set for the sensor, and the communication channel characterizes a wireless communication channel set for the sensor. And, each sensor includes a first wireless communication unit, and the wireless communication connection established between the first wireless communication unit and the second wireless communication unit 220 of each sensor has uniqueness, so that the wireless communication channel between each sensor and the processor 210 has uniqueness. Each sensor has its own device ID, and the processor 210 controls the data application module 213 to send the configuration parameters to the sensor management module 212 through the service module 211 based on the downlink command theme, the sensor management module 212 issues the configuration parameters to the second wireless communication unit 220 first, the second wireless communication unit 220 searches the sensor with the device ID as a target sensor corresponding to the configuration parameters according to the device ID in the configuration parameters, and then determines a wireless communication channel established by the first wireless communication unit of the target sensor, and further issues the configuration data to the target sensor through the wireless communication channel for configuration, thereby implementing accurate issuance of the configuration parameters and accurate configuration of the wireless communication parameters.

Furthermore, the matching of the device IDs can also be achieved by sensors. Specifically, the configuration parameters are simultaneously issued to a plurality of sensors; after the plurality of sensors receive the configuration parameters, the respective device IDs are respectively matched with the device IDs in the configuration parameters, and the successfully matched device IDs are searched. And then determining a working mode and a communication channel corresponding to the successfully matched equipment ID in the equipment parameters, and setting the respective wireless communication mode and the wireless communication channel as the communication mode and the communication channel represented by the respective searched working mode and communication channel, so as to realize the accurate configuration of the wireless communication parameters of each sensor.

It should be noted that each sensor includes an MCU (micro controller Unit) in addition to the first wireless communication Unit, where the first wireless communication Unit may be a chip, and pins of the first wireless communication Unit are soldered to the MCU to realize serial port communication with the MCU. The configuration parameters issued through the wireless communication channel are sent to the MCU through serial port communication, and the MCU configures the wireless communication parameters of the first wireless communication unit. After configuration parameters are issued to each type of sensor and wireless communication parameters of each type of sensor are configured, each sensor uploads the sensing data detected by each sensor to the data application module 213 for processing through the wireless communication channel, the first wireless communication unit, the second wireless communication unit 220, the sensor management module 212 and the service module 211 in sequence. The sensor data detected by each sensor are wirelessly transmitted according to the wireless communication parameters configured by each sensor, and the sensors transmit the sensor data according to different communication channels and communication modes, so that the confusion of the respective sensor data is avoided, and the accurate transmission is facilitated.

Moreover, the uploading periods of the sensors can be the same or different, and can be determined according to the characteristics of the detected sensing data; for example, the sensing data detected by the gas sensor 111 is uploaded in a relatively long period of time, and the sensing data representing the real-time state of the disconnecting link mechanism 110 detected by the angle sensor 112 and the attitude sensor 112 is uploaded in a relatively short period of time.

Furthermore, in this embodiment, at least one data application module receives the target sensing data transmitted by the service module, and performs fusion processing on the target sensing data to obtain a processing result; and the processor can also monitor the state of the disconnecting link mechanism of the high-voltage switch according to the processing result.

Understandably, different data application modules 213 have different application functions, and different states of the knife gate mechanism 110 are monitored by sensing data of different sensors. When transmitting the sensing data to the data application module 213, the service module 211 transmits different sensing data to the data application module 213 according to different application functions of different data application modules 213. Specifically, the required data information may be transmitted to the service module 211 by each data application module 213 in advance, or the data information required by each data application module 213 may be set in the service module 211 in advance. The service module 211 transmits the target sensing data corresponding to the application function of each data application module 213 in the transmission data to each data application module 213 according to the required data information, and the data application modules 213 perform fusion processing on the target sensing data. Moreover, the transmitted target sensing data may include sensing data respectively corresponding to all the data application modules 213, so that each data application module 213 processes the respective target sensing data according to its respective application function; the sensing data corresponding to the partial data application module 213 may also be included, and at this time, the partial data application module 213 processes the corresponding target sensing data according to the application function thereof. In this way, the data application modules 213 fuse the respective target sensing data to obtain a processing result, and monitor different states of the knife gate mechanism 110.

Further, the data application module 213 receives and fuses the target sensor data to obtain a processing result, and the processor 210 in the monitoring device 200 determines whether the knife mechanism 110 in the high voltage switch 100 is abnormal or not by the abnormality of the processing result, thereby realizing the state monitoring of the knife mechanism 110. Specifically, the processor 210 sets a reference result representing a normal state in advance, compares the processed result with the reference result, and determines whether the processed result and the reference result are consistent or not, or whether the similarity is higher than a certain value. If the two are consistent or the similarity is higher than a certain value, the processing result is normal, and the state of the disconnecting link mechanism 110 is judged to be normal. On the contrary, if the processing result is not consistent with the reference result and the similarity is not higher than a certain value, it indicates that the processing result is abnormal, and thus it is determined that the state of the disconnecting link mechanism 110 is abnormal.

In addition, in order to eliminate the abnormality of the knife gate mechanism 110 in time, after the abnormality of the processing result is determined, prompt information is output. Moreover, the prompt message is different according to different types of exception handling results. By outputting the prompt information corresponding to the abnormal processing result, the operation and maintenance personnel can conveniently and quickly determine the abnormal reason for abnormal investigation according to the abnormality reflected by the prompt information when checking the prompt information. Meanwhile, since a plurality of sensors are set in each of the knife switch mechanisms 110, the data application module 213 processes the sensing data of the plurality of sensors in each of the knife switch mechanisms 110, respectively, to obtain a processing result representing whether each of the knife switch mechanisms 110 is abnormal. As long as there is an abnormality in each processing result, a corresponding prompt message is output for the abnormality, so as to quickly find the abnormal disconnecting link mechanism 110 for exception elimination.

Further, in this embodiment, the processor 210 in the monitoring apparatus 200 may be a single-core processor or a multi-core processor. For a single-core processor, the service module 211, the sensor management module 212, and the at least one data application module 213 are all running within the single-core processor. And, the downstream command topic is registered by the at least one data application module 213 to the service module 211, and is subscribed by the sensor management module 212 to the service module 211; upstream data topics are registered by the sensor management module 212 with the service module 211 and subscribed to the service module 211 by at least one data application module 213. For the multi-core processor, besides the service module 211, the sensor management module 212 and the at least one data application module 213, a distribution module is also included; the multi-core processor divides a management core and an application core, the service module 211, the sensor management module 212 and the distribution module run in the management core, at least one data application module 213 runs in the application core, the number of the application cores may be the same as the number of the data application modules 213, and one application core runs one data application module 213. The distribution module is in communication connection with the at least one data application module 213, and the downlink command topic is registered to the service module 211 by the distribution module and is subscribed to the service module 211 by the sensor management module 212; upstream data topics are registered by the sensor management module 212 with the service module 211 and subscribed to the service module 211 by the distribution module.

Further, the uplink command topic and the downlink data topic of this embodiment are preferably implemented by MQTT (Message queue Telemetry Transport) protocol. The MQTT protocol is a message transmission protocol based on a publish/subscribe mode, and comprises a Publisher (Publisher) and a Subscriber (Subscriber); each publisher can send different types of messages, the type of the message is a topic (topic), the messages in the MQTT communication belong to a certain topic, and only subscribers who subscribe to the topic can receive the messages belonging to the topic. Registering an MQTT service terminal on the processor 210 to form a service module 211; meanwhile, the sensor management module 212 and the data application module 213 in the single-core processor or the distribution module in the multi-core processor are registered as MQTT clients, and the MQTT clients register and subscribe topics on the MQTT server, so that wireless communication among the sensor management module 212, the service module 211 and the data application module 213 is realized.

Further, the wireless communication channel formed between the first wireless unit and the second wireless unit 220 is preferably long distance wireless communication by LoRa. LoRa can realize long-distance transmission with low-power consumption, has the good characteristic of interference immunity, transmits the sensing data that each sensor detected to service module 211 through it, has avoided through the interference that wired transmission each item sensing data produced because of the forceful electric power place, and transmission speed is fast.

In addition, an optical fiber is provided between the high voltage switch 100 and the control cubicle, in addition to the wireless communication device between the sensor and the processor 210. The control of the control cubicle on the high-voltage switch 100 is realized by optical fiber communication, the control signal is quickly transmitted to the high-voltage switch 100 through the optical fiber, and the disconnecting link mechanism 110 or the breaker mechanism therein is controlled, so that the disconnecting link mechanism 110 and the breaker mechanism can respond quickly.

Specifically, for the registration and subscription of the message topic in the MQTT, the data application module 213 (single-core processor) or the distribution module (multi-core processor) registers the downlink command topic to the service module 211, and becomes a command publisher of the downlink command topic; the sensor management module 212 subscribes to the downlink command topic from the service module 211, and becomes a command subscriber of the downlink command topic. Through the registration and subscription operation of the downlink command theme, the data application module 213 or the distribution module and the sensor management module 212 are enabled to interface with the same command issuing theme of the service module 211, so as to realize the publishing and subscription of the configuration parameters. The data application module 213 or the distribution module issues the configuration parameters to the service module 211 through the registered downlink command topic, and the sensor management module 212 acquires the configuration parameters from the service module 211 through the subscribed downlink command topic; and then the acquired configuration parameters are issued to each sensor through a wireless communication channel formed between the first wireless unit and the second wireless unit.

Further, for the sensing data uploaded by the multiple sensors, the sensor management module 212 registers an uplink data topic with the service module 211 to become a data publisher of the uplink data topic, and the data application module 213 (single-core processor) or the distribution module (multi-core processor) subscribes the uplink data topic to the service module 211 to become a data subscriber of the uplink data topic. Through the registration and subscription operation of the uplink data theme, the data application module 213 or the distribution module and the sensor management module 212 are enabled to be docked to the same data uploading theme of the service module 211, so that the publishing and subscription of the sensing data are realized. The sensor management module 212 publishes the sensing data transmitted through the wireless communication channel formed between the first wireless unit and the second wireless unit to the service module 211 through the registered uplink data theme, and the data application module 213 or the distribution module acquires the sensing parameters from the service module 211 through the subscribed uplink data theme for fusion processing, so as to realize monitoring of the state of the disconnecting link.

Further, when the processor 210 transmits the configuration parameters based on the downlink command theme, for the single-core processor, the processor controls the at least one data application module 213 to send the configuration parameters preset therein to the service module 211 based on the downlink command theme; the multi-core processor controls at least one data application module 213 to send the preset configuration parameters to the distribution module, and the distribution module transmits the configuration parameters to the service module 211 based on the downlink command theme. Thereafter, the control service module 211 sends the configuration parameters to the sensor management module 212 subscribed to the downlink command topic, and the sensor management module 212 issues the configuration parameters to the plurality of sensors through the wireless communication connection to configure the wireless communication parameters. Meanwhile, when the processor 210 transmits the sensing data based on the uplink data theme, the plurality of sensors upload the detected sensing data to the sensor management module 212 via the wireless communication connection based on the configured wireless communication parameters, and control the sensor management module 212 to send to the service module 211 through the uplink data theme. Thereafter, for the single-core processor, the control service module 211 sends the sensing data to the corresponding data application module 213 for processing based on the uplink data theme; for the multi-core processor, the control service module 211 sends the sensing data to the distribution module based on the uplink data theme, and the distribution module distributes the target sensing data corresponding to the application function of at least one data application module 213 in the sensing data to the corresponding data application module 213 for processing.

Meanwhile, the distribution module or the data application module 213 and the sensor management module 212 are connected to the same theme, so that the configuration parameters are issued and the sensing data are uploaded, only the data of the connected theme is received between the distribution module and the sensor management module 212 or between the data application module 213 and the sensor management module 212, and other data are not received, so that the data application module 213 is favorable for improving the data transmission efficiency and the processing efficiency.

The invention further provides a method for transmitting the sensing data of the high-voltage switch, and fig. 2 is a flow chart of the method for transmitting the sensing data of the high-voltage switch according to the embodiment of the invention.

The sensing data transmission method is applied to a sensing data transmission system of a high-voltage switch shown in figure 1, and comprises the following steps:

step S100, the processor 210 controls at least one data application module 213 to send configuration parameters to the service module 211 based on a downlink command theme, controls the service module 211 to send the configuration parameters to the sensor management module 212, and controls the sensor management module 212 to send the configuration parameters to a plurality of sensors through wireless communication connection;

step S200, configuring wireless communication parameters by a plurality of sensors based on the configuration parameters, and uploading sensing data to the sensor management module 212 via the wireless communication connection based on the wireless communication parameters;

in step S300, based on the uplink data theme, the processor 210 controls the sensor management module 212 to send the received sensing data to the service module 211, and controls the service module 211 to transmit target sensing data corresponding to the application function of at least one data application module 213 in the sensing data to the corresponding data application module 213.

The sensing data transmission method of the high-voltage switch 100 of this embodiment is applied to the sensing data transmission system described in the previous embodiment, and details of the transmission data transmission system are not described herein. The processor 210 has software programs running therein, including a service module 211, a sensor management module 212, and at least one data application module 213. The processor 210 controls the operation of the software program, and implements the control of the at least one data application module 213 to send the preset configuration parameters to the service module 211 by means of the downlink command theme, and controls the service module 211 to send to the sensor management module 212. And further, the sensor management module 212 is controlled to transmit the configuration parameters to the plurality of sensors through a wireless communication channel formed between the first wireless unit and the second wireless unit, so that the plurality of sensors configure the respective wireless communication parameters through the configuration parameters. The sensors detect the knife gate mechanism 110, obtain sensing data representing the state of the knife gate mechanism, perform wireless communication according to the wireless communication parameters, and transmit the sensing data to the sensor management module 212 through a wireless communication channel; the processor 210 controls the sensor management module 212 to issue the received sensing data to the service module 211 based on the uplink data topic, and controls the service module 211 to transmit target sensing data corresponding to the application function of at least one data application module 213 in the sensing data to the corresponding data application module 213 for fusion processing.

Therefore, the wireless transmission of the sensing data is realized by configuring different communication channels for the sensors through the configuration of the wireless communication parameters, the interference of a strong electric field of wired transmission on the transmitted sensing data is avoided, and the transmission speed of the sensing data is improved. Moreover, the sensing data directly faces to the data application module 213, so that reading access after being stored in a database is avoided, and the access efficiency is improved. Therefore, the sensing data is transmitted in a wireless mode through the wireless communication channel, and efficient and accurate transmission of the sensing data is achieved.

Specifically, for step S100, the configuration parameters are preset in the data application module 213, and after the data application module 213 is started, the processor 210 controls the data application module 213 to send the configuration parameters to the service module 211 based on the downlink command theme, and the service module 211 sends the configuration parameters to the sensor management module 212. Thereafter, the processor 210 controls the sensor management module 212 to send the received configuration parameters to each sensor via the wireless communication connection, so as to configure the communication channel parameters of each sensor. Moreover, after configuring the configuration parameters of each sensor, the data application module 213 also issues heartbeat to each sensor at regular time to detect whether the wireless communication channel can communicate normally, so as to ensure that the sensing data is effectively uploaded to the data application module 213 for processing.

Further, the issued configuration parameters at least include a working mode, a device ID and a communication channel, the device ID is used to characterize the set type of the sensor, the working mode characterizes a wireless communication mode set for the sensor, and the communication channel characterizes a wireless communication channel set for the sensor. Aiming at the configuration parameters issued by each sensor, the configuration parameters are carried out according to the equipment ID; specifically, in step S100:

the sensor management module 212 determines a target sensor corresponding to the configuration parameter according to the device ID in the configuration parameter, and issues the configuration parameter to the target sensor via wireless communication connection.

Further, the data application module 213 sends the preset configuration parameters to the service module 211, and the service module 211 receives the configuration parameters and issues the configuration parameters to the sensor management module 212 based on the downlink command theme. Thereafter, the sensor management module 212 issues the received configuration parameters to the sensor for configuring the wireless communication parameters through the wireless communication connection established between the second wireless communication unit 220 and the first wireless communication unit.

Understandably, each sensor comprises a first wireless communication unit, and the wireless communication connection established between the first wireless communication unit and the second wireless communication unit 220 of each sensor has uniqueness, so that the wireless communication channel between each sensor and the processor 210 has uniqueness. Each sensor has its own device ID, and the processor 210 controls the data application module 213 to send the configuration parameters to the sensor management module 212 through the service module 211 based on the downlink command theme, the sensor management module 212 issues the configuration parameters to the second wireless communication unit 220 first, the second wireless communication unit 220 searches the sensor with the device ID as a target sensor corresponding to the configuration parameters according to the device ID in the configuration parameters, and then determines a wireless communication channel established by the first wireless communication unit of the target sensor, and further issues the configuration data to the target sensor through the wireless communication channel for configuration, thereby implementing accurate issuance of the configuration parameters and accurate configuration of the wireless communication parameters.

For step S200, it should be noted that each sensor includes an MCU in addition to the first wireless communication unit, the first wireless communication unit may be a chip, and pins of the first wireless communication unit are soldered to the MCU to realize serial port communication with the MCU. The configuration parameters issued through the wireless communication channel are sent to the MCU through serial port communication, and the MCU configures the wireless communication parameters of the first wireless communication unit. After configuration parameters are issued to each type of sensor and wireless communication parameters of each type of sensor are configured, each sensor uploads the sensing data detected by each sensor to the data application module 213 for processing through the wireless communication channel, the first wireless communication unit, the second wireless communication unit 220, the sensor management module 212 and the service module 211 in sequence. The sensor data detected by each sensor are wirelessly transmitted according to the wireless communication parameters configured by each sensor, and the sensors transmit the sensor data according to different communication channels and communication modes, so that the confusion of the respective sensor data is avoided, and the accurate transmission is facilitated.

For step S300, it is understood that different data application modules 213 have different application functions, and different states of the knife gate mechanism 110 are monitored by the sensing data of different sensors. When transmitting the sensing data to the data application module 213, the service module 211 transmits different sensing data to the data application module 213 according to different application functions of different data application modules 213. Specifically, the required data information may be transmitted to the service module 211 by each data application module 213 in advance, or the data information required by each data application module 213 may be set in the service module 211 in advance. The service module 211 transmits the target sensing data corresponding to the application function of each data application module 213 in the transmission data to each data application module 213 according to the required data information, and the data application modules 213 perform fusion processing on the target sensing data. Moreover, the transmitted target sensing data may include sensing data respectively corresponding to all the data application modules 213, so that each data application module 213 processes the respective target sensing data according to its respective application function; the sensing data corresponding to the partial data application module 213 may also be included, and at this time, the partial data application module 213 processes the corresponding target sensing data according to the application function thereof. In this way, the data application modules 213 fuse the respective target sensing data to obtain a processing result, and monitor different states of the knife gate mechanism 110. For the plurality of data application modules 213, the sensing data of different sensors are fused and processed in different ways, so that the detection of various different states of the disconnecting link is realized, and the safety of the disconnecting link state is ensured from multiple aspects.

Further, in this embodiment, the processor 210 in the monitoring apparatus 200 may be a single-core processor or a multi-core processor. When the processor 210 is a single-core processor, the step S100 further includes the steps of:

s10, the processor 210 controls the at least one data application module 213 to register the downstream command topic with the service module 211, and controls the sensor management module 212 to subscribe the downstream command topic with the service module 211;

s20, the processor 210 controls the sensor management module 212 to register the upstream data topic with the service module 211 and controls the at least one data application module 213 to subscribe the upstream data topic with the service module 211.

When the processor 210 is a multi-core processor, the step S100 further includes the steps of:

s11, the processor 210 controls the distribution module to register the downlink command topic with the service module 211, and controls the sensor management module 212 to subscribe the downlink command topic with the service module 211;

s21, the processor 210 controls the sensor management module 212 to register the upstream data topic with the service module 211, and controls the distribution module to subscribe the upstream data topic with the service module 211.

The processor 210 in the monitoring device 200 of this embodiment may be a single-core processor or a multi-core processor, but both the single-core processor and the multi-core processor preferably implement the uplink command theme and the downlink data theme by using the MQTT protocol. Specifically, at least one data application module 213 (single core processor) or distribution module (multi-core processor) registers a downlink command topic with the service module 211 to become a command issuer of the downlink command topic; the sensor management module 212 subscribes to the downlink command topic from the service module 211, and becomes a command subscriber of the downlink command topic. Through the registration and subscription operation of the downlink command theme, the data application module 213 or the distribution module and the sensor management module 212 are enabled to interface with the same command issuing theme of the service module 211, so as to realize the publishing and subscription of the configuration parameters. The data application module 213 or the distribution module issues the configuration parameters to the service module 211 through the registered downlink command topic, and the sensor management module 212 acquires the configuration parameters from the service module 211 through the subscribed downlink command topic; and then the acquired configuration parameters are issued to each sensor through a wireless communication channel formed between the first wireless unit and the second wireless unit, so that the configuration of the communication channel of each sensor is realized.

Further, another embodiment of the sensing data transmission method of the high-voltage switch is provided.

Fig. 3 is a flowchart of another embodiment of the sensing data transmission method of the high-voltage switch according to the present invention, which is different from the embodiment of the sensing data transmission method of the high-voltage switch described above in that after step S300, the method further includes:

step S400, at least one data application module 213 receives the target sensing data transmitted by the service module 211, and performs fusion processing on the target sensing data to obtain a processing result;

in step S500, the processor 210 monitors the state of the disconnecting link mechanism 110 of the high-voltage switch 100 according to the processing result.

After the service module 211 of this embodiment transmits the target sensing data corresponding to the application function of at least one data application module 213 in the sensing data to the data application module 213, the data application module 213 receives and fuses the target sensing data to obtain a processing result, and the processor 210 in the monitoring device 200 determines whether the knife gate mechanism 110 in the high voltage switch 100 is abnormal according to the abnormality of the processing result, thereby implementing the state monitoring of the knife gate mechanism 110. Specifically, the processor 210 sets a reference result representing a normal state in advance, compares the processed result with the reference result, and determines whether the processed result and the reference result are consistent or not, or whether the similarity is higher than a certain value. If the two are consistent or the similarity is higher than a certain value, the processing result is normal, and the state of the disconnecting link mechanism 110 is judged to be normal. On the contrary, if the processing result is not consistent with the reference result and the similarity is not higher than a certain value, it indicates that the processing result is abnormal, and thus it is determined that the state of the disconnecting link mechanism 110 is abnormal.
