[0028] The embodiment of the present invention provides a device data acquisition and processing system. Figure 1 The following is a schematic block diagram of a device data acquisition and processing system provided by an embodiment of the present invention. Figure 1 As shown, the device data acquisition and processing system includes a sensor device, a remote terminal unit and a database. The database is used to preset the sensor device instruction table information. Specifically,

[0029] The remote terminal unit obtains the instruction table information of the sensor device from the database; wherein the instruction table information of the sensor device includes the sensor type, instruction symbol, execution cycle, and Lua scripts for different execution purposes.

[0030] In this embodiment, the remote terminal unit obtains the sensor device instruction table information from the sqlite database; wherein the sensor device instruction table information includes the sensor type, instruction symbol, execution cycle, and Lua scripts for different execution purposes. For example, the sensor type is a PH sensor, the instruction symbol is to read the pH value, the execution cycle is 3 seconds, and the Lua script is used for parsing purposes.

[0031] It should be noted that there are many ways for the remote terminal unit to obtain the sensor device instruction table information from the sqlite database, for example, remotely burning the sqlite database into the remote terminal unit, or the remote terminal unit synchronously downloading the sensor device instruction table information in the database through the network, thereby avoiding a lot of development costs and data collection costs.

[0032] In one embodiment, after the remote terminal unit obtains the sensor device instruction table information from the database, the remote terminal unit responds to a sensor device instruction table information update request initiated by the external network to update the sensor device instruction table information in the database in real time.

[0033] In one embodiment, after the remote terminal unit obtains the sensor device instruction table information from the database, the remote terminal unit sends a sensor device instruction table information update request to the external network based on a preset time period, such as 30 minutes, to update the sensor device instruction table information in the database.

[0034] Different from the prior art method that requires the sensor device to be connected to the remote terminal unit through the traditional hardware protocol before data collection and processing can be performed, this embodiment presets the sensor device instruction table information through a database, which not only greatly reduces the complexity of installation and debugging between the hardware device and the remote terminal unit, but also reduces the cost of data collection and processing.

[0035] The remote terminal unit is also used to send the instruction symbol to the corresponding type of sensor device based on the execution cycle in the sensor device instruction table information, and the corresponding type of sensor device returns the instruction result corresponding to the instruction symbol to the remote terminal unit based on the received instruction symbol.

[0036] In this embodiment, first, the remote terminal unit sends the instruction symbol to the corresponding type of sensor device based on the instruction execution cycle in the sensor device instruction table information.

[0037] Specifically, the remote terminal unit sends the instruction symbol to the corresponding type of sensor device based on the execution cycle in the sensor device instruction table information, including: the remote terminal unit takes the instruction symbol data of each sensor device contained in the sensor device instruction table information as a task and puts it into the task pool; then the remote terminal unit obtains the instruction symbol data of each sensor device from the task pool in sequence based on the execution cycle corresponding to the instruction symbol data of each sensor device, such as 3 seconds, and sends it to the corresponding type of sensor device to execute the corresponding task.

[0038] Next, the sensor device of the corresponding type receives the instruction character: 010301000002C5 F7, and based on the received instruction character, transmits the instruction result corresponding to the instruction character: 01030400C002AE 7AD3 back to the remote terminal unit.

[0039] The above is the process of the remote terminal unit automatically reading the sensor device data. However, in some cases, the installation height, pipe diameter and other data registered when the sensor device is installed on site need to be written into the remote terminal unit. Since these on-site parameters are often recognizable by humans, but cannot be directly recognized by machines, these on-site parameters need to be converted into machine-recognizable data before processing.

[0040] Based on the above reasons, in one embodiment, before the corresponding type of sensor device returns the instruction result corresponding to the instruction symbol based on the received instruction symbol to the remote terminal unit, it also includes: if it is necessary to manually write the field parameters of the sensor device into the remote terminal unit based on the actual situation, the remote terminal unit receives the field parameters of the sensor device, and performs parameter conversion processing on the field parameters through the second Lua script in the sensor device instruction table information to obtain the instruction symbol of the sensor device; the remote terminal unit sends the instruction symbol of the sensor device to the corresponding type of sensor. It should be noted that the second Lua script in this embodiment is used to convert and assemble the field parameters into an instruction symbol that can be recognized by the sensor.

[0041] The remote terminal unit receives the command result, and obtains and executes the corresponding first lua script from the sensor device command table information.

[0042] In this embodiment, the remote terminal unit receives the command result returned by the sensor device, and obtains and executes the first Lua script corresponding to the command result returned by the sensor device from the sensor device command table information. It should be noted that the first Lua script is used to parse the command result returned by the sensor device.

[0043] The remote terminal unit parses the instruction result based on the custom conversion function in the first lua script, obtains parsed data, and stores the parsed data in a local preset area.

[0044] In this embodiment, the remote terminal unit parses the instruction result based on the custom conversion function in the first lua script, obtains parsed data, and stores the parsed data in a local preset area.

[0045] In one embodiment, after the remote terminal unit parses the instruction result based on the custom conversion function in the first lua script, obtains the parsed data, and stores the parsed data in the local preset area, the remote terminal unit obtains the parsed data from the local preset area. Then, the remote terminal unit pushes the parsed data to the corresponding service object based on the preset push strategy. Specifically, the remote terminal unit pushes the parsed data to the corresponding service object based on the preset push cycle and push method in the database, such as using MQTT, HTTP or websocket push methods. It should be noted that for low-power devices, the push cycle of the parsed data should not be too fast, otherwise it will cause excessive power consumption.

[0046] In one embodiment, when the remote terminal unit pushes the parsed data to the corresponding service object based on the preset push strategy, if a network failure occurs during the push process resulting in a push failure, the current parsed data will continue to be saved in the local preset area to wait for subsequent push retries; if the push still fails after a preset number of push retries, the current parsed data will be cleared to avoid memory pressure on the microcontroller; if no network failure occurs during the push process and the push is successful, the current parsed data will be deleted from the local preset area.

[0047] In the device data acquisition and processing system provided by the embodiment of the present invention, the remote terminal unit obtains the sensor device instruction table information from the database; wherein the sensor device instruction table information includes the sensor type, instruction symbol, execution cycle, and Lua scripts with different execution purposes; the remote terminal unit sends the instruction symbol to the corresponding type of sensor device based on the execution cycle in the sensor device instruction table information, and the corresponding type of sensor device returns the instruction result corresponding to the instruction symbol to the remote terminal unit based on the received instruction symbol; the remote terminal unit receives the instruction result, and obtains and executes the corresponding first Lua script from the sensor device instruction table information; the remote terminal unit parses the instruction result based on the custom conversion function in the first Lua script, obtains the parsed data, and stores the parsed data in the local preset area. In the above system, the instruction table information of the sensor device is preset by means of a database, which mainly includes data information, data acquisition instructions and parsing functions. Therefore, when collecting and processing data, it is different from the prior art method that requires the sensor device to be connected to the remote terminal unit through the traditional hardware protocol before data collection and processing can be carried out. The present invention only needs to let the remote terminal unit download the sensor device instruction table information in the database through external instructions, and can realize the collection of device data based on the information in the instruction table, as well as the subsequent analysis and transmission, which greatly reduces the data collection cost, realizes the unified management of the parsing conversion function, reduces the system management and maintenance cost, and as time goes by, the continuously enriched database can adapt to the collection of more different devices.
