[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example:

[0034] The embodiment of the present invention provides a communication method, which obtains data information of an air source heat pump device by utilizing a data acquisition end and transmits it to a data gateway end. The data gateway end can display the real-time data of the air source heat pump device in real time, and the data gateway end can generate instructions, and send a final instruction signal to a control terminal through a data receiving end to complete the control and monitoring of the air source heat pump device; at the same time, the data receiving end adopts a dual-mode structural framework with an active data end and a semi-dormant data end. Under normal circumstances, the data receiving end enables the semi-dormant data end, and performs power reduction operation based on the data acquisition module and the real-time monitoring module in the semi-dormant data end. When an early warning occurs in the real-time monitoring module, the active data end is activated and the conversion is completed. At this time, the entire device is in full-power operation, thereby completing the rapid circulation and transmission of the instruction signal data information flow, and ensuring the timeliness and accuracy of data information transmission.

[0035] The data acquisition terminal communicates with the air source heat pump equipment through the RS-485 serial port. In actual application, the technician installs the acquisition device used by the data acquisition terminal on the air source heat pump equipment, connects the acquisition device to the air source heat pump equipment, and then uploads the air source heat pump information to the data acquisition module. The air source heat pump equipment information is arranged in alphabetical order, from equipment A to equipment Z, so that it can quickly distinguish the location and equipment information mark;

[0036] like Figure 1 As shown, the following steps are included:

[0037] Step 1. Generate an acquisition instruction according to the acquired air source heat pump device, wherein the acquisition instruction is used to send to the data gateway end, and the data gateway end calls the protocol conversion template according to the acquisition instruction;

[0038] Step 2. Obtain the protocol conversion template, generate and send a first control instruction based on the protocol conversion template and according to the first operation instruction sent by the data gateway, and the control instruction follows the communication protocol between the data acquisition module and the air source heat pump device;

[0039] Step 3. Based on the protocol conversion template, generate first communication information according to the first feedback information sent by the air source heat pump device, and the communication information complies with the communication protocol between the data gateway and the data acquisition module;

[0040] Step 301. Control the operation of the device based on the control terminal according to the first control instruction; monitor the device feedback signal in real time based on the real-time monitoring module, analyze the warning information according to the device feedback signal and report it for processing, and activate the semi-dormant data terminal at the same time;

[0041] Specifically, the control terminal generates control instructions according to business needs or user settings, and can use the state machine model to determine the required operation of the device. The real-time monitoring module is configured with a series of sensors (temperature, pressure, vibration, etc.) to collect device operation data in real time; and the feedback signal is obtained through the following formula to set the sampling frequency f s (H z ):

[0042]

[0043] Where T s is the sampling period.

[0044] The data vector S of the feedback signal is retained, for example:

[0045] S=(S 1 ,S 2 ,S 3 ,S 4 ···,S n )

[0046] The early warning analysis uses the statistical analysis method Z-score for anomaly detection:

[0047]

[0048] Where X is the current monitoring value, μ is the sample mean, σ is the sample standard deviation, and if Z exceeds the preset value, it is marked as abnormal.

[0049] For the setting of semi-sleep mode, when the device is in a non-critical operating state but still needs to be monitored, the semi-sleep mode is enabled to reduce power consumption, and the state transition rules are defined, using the Markov decision process (MDP) model. The conditions of the semi-sleep mode are triggered by a specific state of the feedback signal. For example, the device is set to be in a state of T consecutive time windows (T sleep ), if the feedback signal is stable within a safe range, it can switch to semi-sleep mode.

[0050] Step 4. The second operation instruction sent by the data gateway generates and sends a second control instruction, and the control instruction complies with the communication protocol between the data acquisition module and the air source heat pump device;

[0051] Step 5. Generate second communication information according to the second feedback information sent by the air source heat pump device, and the communication information complies with the communication protocol between the data gateway and the data acquisition module;

[0052] Step 501. Control the operation of the device according to the second control instruction; meanwhile, analyze the information based on the second feedback signal of the device and report and process it through the active data terminal.

[0053] Specifically, receive the second control instruction and send corresponding operation commands to the device based on the content of the instruction. In this process, the state machine model can be used to judge the operating state and instruction type of the device, including operations such as turning on, turning off, and adjusting device parameters;

[0054] Obtain the second feedback signal f of the device in real time 2 , including vectors of device parameters such as temperature and on-state data, and then set the sampling frequency f s ' of the feedback signal:

[0055]

[0056] where T s ' is the new sampling period.

[0057] Subsequently, use a threshold-based judgment algorithm to analyze the feedback signal and set the normal range [L, H] of the feedback signal:

[0058] If F 2 < L or F 2 > H, it is marked as abnormal.

[0059] The steps for converting the semi-dormant mode to the active mode include: according to the change of the feedback signal, set the condition to trigger the release of the semi-dormant mode. For example, when the device is in a stable operating state for more than the set time T C ,

[0060] If the duration of the stable state > T C then it is converted to the active mode. When the device is converted from the semi-dormant mode to the active data terminal, the data transceiver module and communication protocol unit of the original data receiving end are started, so as to quickly restore the data transmission function.

[0061] Referring to Figure 1 and Figure 2 , this example also includes a communication device, which includes:

[0062] A data gateway terminal, used to publish and receive instructions as a data port platform;

[0063] A data receiving end, used to obtain the operating data of each device and perform data reception and transmission;

[0064] A control terminal, used to receive the instructions sent by the data gateway terminal and control the operation of the device;

[0065] At the same time, an electronic device is used, which includes: a memory and a processor, wherein a computer program is stored on the memory, and the processor implements the method described above when executing the program; and is based on a computer-readable storage medium, which stores a computer program, and the program implements the method described above when executed by the processor.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
