As used in the specification and appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0041] As used in this specification and the appended claims, the term "if" can be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of [described condition or event]" or "in response to detecting [described condition or event]," depending on the context.

[0042] Example:

[0043] A wireless ad hoc multifunctional network data collector, see Figure 1 ,include:

[0044] Memory 1: used to store acquisition models;

[0045] Configuration unit 2: used to read the acquisition model, or receive and load the acquisition model from the cloud device;

[0046] Communication unit 3: used to establish a network with the collected device and the cloud device, generate communication instructions using the collection model, communicate with the collected device using the communication instructions, and collect data from the collected device.

[0047] In this embodiment, the collection model can be a communication protocol between the network data collector and other devices (e.g., a cloud device or a device being collected). The network data collector can have a built-in collection model when it leaves the factory. In this way, when the network data collector is used for the first time, it can read the built-in collection model and communicate with other devices based on the collection model. During subsequent use, the network data collector can also read the collection model of the cloud device and replace the collection model stored in the memory 1.

[0048] In this embodiment, the collection model in the network data collector can be updated actively or passively. For example, the active update method is that when the user wants to change the function of the network data collector and collect another type of data, he or she can initiate a request to the cloud device to load the collection model corresponding to the other type of data. After receiving the request, the cloud device returns the collection model to the network data collector. The passive update method is that when the collection model in the cloud device is updated, the new collection model is sent to the network data collector, and the network data collector stores and loads the new collection model. The administrator can modify the collection model directly on the cloud device, or upload the new collection model to the cloud device, thereby replacing the original collection model on the cloud device.

[0049] In this embodiment, the communication unit 3 plays a networking function. For example, the communication unit 3 can have its own wireless MESH routing function and communicate with other networks to realize a dynamic and continuously expanding network architecture, so that the network data collector can be wirelessly connected to other devices. The communication unit 3 generates a communication instruction based on the acquisition model and transmits it to the collected device. When a response instruction from the collected device is received, the acquisition model is used to parse the response instruction to obtain the response data of the collected device, thereby realizing communication between the network data collector and the collected device. Similarly, if the network data collector communicates with other devices (such as edge computers), the acquisition model is used to generate a communication instruction and transmit it to the other devices. When a response instruction from the other devices is received, the acquisition model is used to parse the response instruction to obtain the response data of the other devices, thereby realizing communication between the network data collector and other devices.

[0050] The wireless ad hoc multifunctional network data collector changes its function by pulling the collection model of the cloud device, so that the network data collector can adaptively update the collection model, thereby improving the applicability and efficiency of the network data collector.

[0051] Furthermore, in some embodiments, the communication unit 3 is specifically configured to:

[0052] Generate communication instructions using the acquisition model and put the communication instructions into the priority queue;

[0053] Read the communication instructions in the priority queue and send them to the collected device;

[0054] Receive response instructions from the collected equipment;

[0055] The response instruction is parsed using the acquisition model to obtain the response data.

[0056] In this embodiment, during communication, communication unit 3 places generated communication instructions into a priority queue, which can be a first-in, first-out queue, thereby implementing a first-come, first-served approach. Each time, communication unit 3 reads a communication instruction from the priority queue and sends it to the device being collected. Upon receiving a response instruction, it uses the collection model to parse the response instruction to obtain response data.

[0057] Furthermore, in some embodiments, the communication unit 3 is further configured to:

[0058] Send the response data to the requesting device.

[0059] In this embodiment, the requesting device can be a third-party application, a third-party official account, a third-party mini-program, etc. The requesting device can request data from the network data collector. When the network data collector parses and obtains the corresponding response data, it can send the response data to the requesting device, and the user can view the response data through the requesting device.

[0060] Furthermore, in some embodiments, the data frame structure of the acquisition model includes:

[0061] Device address code, function instruction, XOR check code, instruction length, extended instruction, MAC address, data field, CRC check field.

[0062] In this embodiment, the data frame structure of the acquisition model may include the following fields:

[0063] Device address code: 1 byte, value range is 1-255;

[0064] Function instruction: 1 byte, value range is 1-255;

[0065] XOR check code: 1 byte, which is the XOR of the device address code and the function instruction;

[0066] Instruction length: 1 byte, value is N+8;

[0067] Extended instruction: 2 bytes;

[0068] MAC address: 4 bytes;

[0069] Data field: N bytes; N is equal to 1-240;

[0070] CRC check field: 2 bytes, uses the CRC check method to check the data from the device address code to the end of the data field, and can use the CRC16 check method.

[0071] In this embodiment, when the network data collector receives a response instruction, it first determines the length, frame header, and CRC checksum, and then performs data parsing after the checksum passes. For example, if the received response instruction is: FC 03FF 10 01 01 191C BD CC ff ff ff ff ff ff ff ff 06 97, FC is the device address code, 03 is the function instruction, FF FC 03 is the XOR checksum, 10 is the instruction length, 0101 is the extended instruction, 19 1C BD CC is the MAC address, ff ff ff ff ffff ff is the data field, and 06 97 is the CRC checksum field. When parsing the response instruction, if the network data collector receives the response instruction in hexadecimal data, it can perform decimal conversion. For example, the decimal value of FF is 255. During the acquisition model parsing process, if there are bit flag fields, they are identified as binary bits to obtain the relevant functional status in the response instruction. Finally, the network data collector can uniformly convert the response data into JSON object format and push it to the requesting device. Similarly, if the communication data received by the network data collector is in JSON object format, the JSON object format is encapsulated into a hexadecimal array according to the collection model, and the communication instruction is obtained and sent to other devices or the collected device.

[0072] Furthermore, in some embodiments, the configuration unit 2 is specifically configured to:

[0073] Regularly check whether there is a new collection model on the cloud device. If so, delete the existing collection model and receive and load the new collection model.

[0074] In this embodiment, the network data collector can detect whether the cloud device has a new collection model every ten minutes. If so, the current collection model of the network data collector is replaced.
