[0021] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0022] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The main solutions of the embodiments of this application are: Receive business data sent by the target device; Based on a preset connection protocol, the service data is parsed to obtain service interaction information; Determining whether the service interaction information belongs to normal service data; If not, the abnormal business corresponding to the business interaction information is processed through a preset docking document. After the processing is completed, a connection is established with the target device. The preset docking document is used to process various abnormal business data during the device connection process.

[0024] In the prior art, when the cloud and hardware devices communicate and connect according to the protocol, due to the strong dependence between the cloud business and the device business, the hardware device logic module is not applicable when other hardware is connected to the cloud, so connection abnormalities will occur, resulting in slow communication between the cloud and the device.

[0025] The present application proposes a device connection method, apparatus, equipment, storage medium and computer program product. The present application receives business data sent by a target device, parses the business data based on the preset connection protocol, obtains business interaction information, and when it is determined that the business interaction information does not belong to normal business data, processes the abnormal business corresponding to the business interaction information through a preset docking document. After the processing is completed, a connection can be established with the target device. Since the preset docking document can process a variety of abnormal business data during the device connection process, when the device is abnormally connected to the cloud, the abnormal business that occurs can be processed in a timely manner to speed up the connection speed between the device and the cloud.

[0026] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a device connection device, etc. The following takes the device connection device as an example to illustrate this embodiment and the following embodiments.

[0027] Based on this, the present application embodiment provides a device connection method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the device connection method of the present application.

[0028] In this embodiment, the device connection method includes steps S10 to S40: Step S10, receiving service data sent by the target device; It should be noted that the target device may be different devices for different application scenarios, wherein the target device may be a car, a refrigerator, a stereo, etc., without specific limitation.

[0029] It should be noted that the business data may be the business interaction data between the target device and the cloud. In the process of business interaction, multiple businesses may be generated. Taking the charging scenario as an example, the business data may be charging services, device connection instructions, and charging setting parameters, etc., without specific limitation.

[0030] Step S20, parsing the service data based on a preset connection protocol to obtain service interaction information; It should be noted that the preset connection protocol can be a network connection protocol between the target device and the cloud, for example, it can be an OCPP protocol, and the transmission architecture is websocket. OCPP (Open Charge Point Protocol) is an open standard protocol for communication between electric vehicle charging stations and central management systems. OCPP messages usually use the JSON format and include two parts: request and response.

[0031] It should be noted that the business data is the request data sent by the target device. The business data is parsed through the preset connection protocol. By extracting the business operations and business parameters, the business interaction required between the two can be determined, and then the business interaction information can be obtained.

[0032] In a feasible implementation manner, the step of parsing the service data based on the preset connection protocol to obtain the service interaction information includes: Based on the preset connection protocol, parsing the character string in the business data into a code object; Extracting the operation type corresponding to the code object; It should be noted that, by using the preset connection protocol, the character string in the business data is extracted, the character string is parsed into a code object (such as a JSON object), and the message ID, operation type, and data field are extracted from the JSON object. Depending on the type of operation, the parsed data can be further processed. For example, the startup information of the device can be recorded, or the status of the device can be updated.

[0033] The processing function corresponding to the operation type is called, and the code object is parsed and processed by the processing function to obtain business interaction information.

[0034] It should be noted that after determining the business operation type corresponding to the code object, the processing function corresponding to the operation type is called to parse the code object through the processing function and extract the business interaction information, thereby realizing effective communication between the device and the cloud system.

[0035] Step S30, determining whether the service interaction information belongs to normal service data; It should be noted that the business interaction information can be normal business data or abnormal business data. When the business interaction information belongs to normal business data, the target device and the cloud can be connected normally without the need for abnormal business processing. When the business interaction information does not belong to normal business data, abnormal business processing is required before the connection between the device and the cloud can be established normally.

[0036] Step S40: If it does not belong, the abnormal business corresponding to the business interaction information is processed through a preset docking document. After the processing is completed, a connection is established with the target device. The preset docking document is used to process various abnormal business data during the device connection process.

[0037] It should be noted that the preset docking document includes protocol specifications, the format of each signal, how to establish a communication connection, and how to handle abnormal services, such as timeouts and network interruptions. When abnormal services corresponding to business interaction information are identified, the corresponding business processing solutions can be called to handle them, thereby ensuring normal connection between the device and the cloud.

[0038] It should be noted that the process of processing the abnormal business corresponding to the business interaction information through the preset docking document may be: Identify abnormal business in the interactive data; based on the abnormal business, call the business processing solution in the preset docking document; based on the business processing solution, process the abnormal business, and after the processing is completed, establish a connection with the target device.

[0039] Among them, abnormal business includes: 1. The hardware device did not return the expected signal.

[0040] 2. The enumeration value in the A signal returned by the hardware device is not defined in the protocol.

[0041] 3. Hardware device response timeout.

[0042] 4. The network connection is interrupted.

[0043] Abnormal business can be handled in the following ways: 1. Record logs, send retry requests, or take other measures based on business logic.

[0044] 2. Record the log and send a confirmation request, asking the device to resend the correct signal.

[0045] 3. Record logs, send retry requests, and set a reasonable timeout.

[0046] 4. Record logs, try to re-establish the connection, and use the heartbeat mechanism to keep the connection active.

[0047] In a feasible implementation manner, after the step S40 of processing the abnormal business corresponding to the business interaction information by using the preset docking document, the method further includes: When it is detected that the preset docking document cannot handle the abnormal business, updating the preset docking document according to the business type corresponding to the abnormal business; It should be noted that most of the solutions for handling abnormal business are included in the preset docking document. When the preset docking document cannot solve the abnormal business, it is necessary to update the preset docking document according to the business type of the abnormal business. The updating method can be that technical personnel analyze and process the abnormal business to obtain a new solution, and then store the new solution in the preset docking document.

[0048] The abnormal business is processed with the updated preset docking document, or the abnormal business is ignored, and the warning information corresponding to the abnormal business is reported.

[0049] It should be noted that the abnormal business is processed with the updated preset docking document to ensure that the preset docking document can handle the abnormal business normally. It is also possible to ignore the processing steps of the abnormal business, establish a connection between the target device and the cloud, and report the warning information corresponding to the abnormal business to the user end, so that technical personnel can handle the abnormal business in a timely manner.

[0050] In a feasible implementation manner, after the step S40 of establishing a connection with the target device after the processing is completed, the method further includes: Sending a heartbeat signal to the target device at every preset time period to monitor the connection status of the target device; It should be noted that the preset time period can be 10S, 30S, etc., and can be changed according to user needs without specific limitation.

[0051] It should be noted that the heartbeat mechanism is used to keep the connection active, send heartbeat signals regularly, monitor the connection status between the target device and the cloud, and immediately try to re-establish the connection once the connection is interrupted.

[0052] When it is determined that the connection state is an interrupted state, a connection instruction is sent to the target device to re-establish a connection with the target device.

[0053] It should be noted that when it is determined that the connection state is an interrupted state, a connection instruction is immediately sent to the target device, so as to re-establish a connection with the target device.

[0054] The present application proposes a device connection method, apparatus, equipment, storage medium and computer program product. The present application receives business data sent by a target device, parses the business data based on the preset connection protocol, obtains business interaction information, and when it is determined that the business interaction information does not belong to normal business data, processes the abnormal business corresponding to the business interaction information through a preset docking document. After the processing is completed, a connection can be established with the target device. Since the preset docking document can process a variety of abnormal business data during the device connection process, when the device is abnormally connected to the cloud, the abnormal business that occurs can be processed in a timely manner to speed up the connection speed between the device and the cloud.

[0055] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 2 , before the step of receiving the service data sent by the target device, it also includes: steps S01~S04: Step S01, receiving an analog signal from a target device; It should be noted that before the target device performs a service connection, it is necessary to receive an analog signal of the target device, wherein the analog signal is used to simulate an abnormal service scenario that may occur in the target device.

[0056] Step S02, performing protocol verification on the analog signal to determine whether the protocol between the cloud and the target device is consistent; It should be noted that before the connection is made, the protocol between the target device and the cloud is verified through an analog signal sent by the target device. Only when the protocols of the two are consistent can the connection be established. When the protocols of the two are inconsistent, data cannot be sent to each other.

[0057] Step S03, after determining that the protocol between the cloud and the target device is consistent, based on the simulation signal, simulate the abnormal interaction signal in the target device to obtain a service processing solution; It should be noted that after confirming that the protocol between the cloud and the target device is consistent, the abnormal business scenario of the target device is simulated by simulating the signal. The abnormal business scenario can be simulated by simulating the abnormal interaction signal, and then processing the abnormal interaction signal to obtain the corresponding business processing solution.

[0058] Step S04: Generate a preset docking document based on the business processing solution.

[0059] It should be noted that for each simulation signal, an abnormal business scenario of the target device can be simulated. In the process of generating a preset docking document, multiple simulation signals of the target device can be received to simulate multiple abnormal interaction signals, and then multiple business processing solutions can be generated. After integrating and storing each business processing solution, a preset docking document can be generated.

[0060] In a feasible implementation manner, when the enumeration value of the simulated signal is not in the preset connection protocol, the step S03 of simulating the abnormal interaction signal in the target device based on the simulated signal to obtain the service processing solution includes: Based on the simulation signal, construct a response signal containing an invalid enumeration value in the target device; It should be noted that when an analog signal of a target device is received, if the enumeration definition in the analog signal is not in the protocol definition, a response signal containing an invalid enumeration value in the target device is constructed through the analog signal.

[0061] After replacing the invalid enumeration value in the response signal with a preset default value or ignoring the invalid enumeration value, generating a processing result; It should be noted that invalid enumeration values ​​are replaced by preset default values ​​to ensure that the system continues to run, or after ignoring invalid enumeration values, the next step of business processing can be guaranteed to run normally and then generate processing results.

[0062] When the processing result shows that the exception processing is completed, a business processing plan is generated.

[0063] It should be noted that when the processing result shows that the exception processing is completed, the processing plan is recorded and a corresponding business processing plan is generated.

[0064] It should be noted that the business processing solution may also be: 1. Record invalid values ​​and their timestamps in a log file for later analysis.

[0065] 2. Send alerts or notifications to relevant personnel so that the problem can be handled in a timely manner.

[0066] In this embodiment, by receiving an analog signal from a target device and processing abnormal business scenarios of the target device with the analog signal, a docking document containing multiple business processing solutions is generated, thereby ensuring abnormal business processing during the connection between the device and the cloud.

[0067] For example, to help understand the implementation process of the device connection method obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 3 , Figure 3A schematic diagram of an implementation flow of a device connection method is provided, specifically: By defining the connection between the target device and the cloud, building a connection protocol (configuring the response string), parsing the signal of the target device through the cloud, determining whether the numerical value is parsed correctly and whether the value is correct, and then constructing the data logic that conforms to the scenario, for example, when constructing a scenario where the cloud sends a charging signal and the hardware does not respond within 2 minutes, the logic is changed, setting the thread to sleep for 2 minutes, and then giving the corresponding ACK response processing solution, thereby completing the robustness check of the cloud, and then establishing the connection between the cloud and the target device.
