DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] In one embodiment, a dynamic adaptation system for IoT devices is provided. The usage scenario of the system is an IoT platform or a platform that needs to connect to various IoT devices (such as access control, parking, cameras, etc.). Based on the dynamic adaptation system for IoT devices, unified management of various types of IoT devices from various manufacturers can be achieved, and relevant remote control of the devices can be performed, and the operating status of the devices can also be monitored.

[0021] like Figure 1 As shown, the IoT device dynamic adaptation system consists of a business module and an adaptation module; The business module includes several submodules, which are used to send the operation instructions and related parameters corresponding to the IoT devices to the adapter module by calling the unified interface process of the adapter module when interacting with various types of IoT devices from various manufacturers, and receive the return results of the IoT devices forwarded by the adapter module, so as to realize the non-differential adaptation interaction between the business module and various types of IoT devices from various manufacturers based on the adapter module; wherein the related parameters include the manufacturer code, device type and business parameters of the IoT devices; The adaptation module includes an information storage and query unit, a parameter mapping unit, and a communication template execution unit. The principle of implementing the indiscriminate adaptation and interaction between the business module and various types of IoT devices from various manufacturers based on the adaptation module is as follows: Figure 2 shown.

[0022] Among them, the information storage and query unit is used to configure and maintain the corresponding operation instructions, communication templates written in groovy language, communication information of each manufacturer, and input parameter templates and output parameter templates corresponding to the operation instructions for various types of IoT devices of various manufacturers before interaction, and send all operation instructions to the business module; when interacting, the communication templates, communication information, and input parameter templates and output parameter templates corresponding to the operation instructions of the IoT device are queried according to the operation instructions and related parameters sent by the business module.

[0023] Specifically, the operation instructions are defined as dictionary values, which are used to provide the business module with the adapter module. Based on the operation instructions, the business module does not need to pay attention to which manufacturer the IoT device is from and what the interaction protocol is, thereby improving the interaction efficiency between the business module and the IoT device. Specifically, the operation commands defined for access control type devices are: remote door opening, face delivery, and communication record query. The operation commands defined for parking type devices are: channel information query, lifting the bar, whitelist delivery, and communication record query. The operation commands defined for camera type devices are: obtain real-time playback stream, playback directory query, obtain playback playback stream, and pan / tilt control.

[0024] Specifically, the communication template, communication information, and input and output templates corresponding to the operation instructions are maintained in the dictionary table, and are permanently used after one maintenance. When modifications are required, they can be modified and updated using the dynamic loading feature of the groovy language. The above information can be configured on the page without writing code, which is convenient and quick.

[0025] Specifically, the communication template is used to configure the communication method used when interacting with IoT devices, including HTTP (Hypertext Transfer Protocol) communication template, SOCKET (socket) communication template and MQTT (Message Queuing Telemetry Transport) communication template.

[0026] Among them, the HTTP communication template uses the HTTP protocol to interact with IoT devices, and specifically defines HTTP communication methods such as GET, POST, PUT, and DELETE; among them, the GET method is used to obtain resources from the server, the POST method is used to submit data to the server, the PUT method is used to upload or update resources to the server, and DELETE is used to delete resources on the server. The OCKET communication template uses the SOCKET method to interact with IoT devices, and the MQTT communication template uses the message publishing and subscription method to interact with IoT devices.

[0027] The communication template written in Groovy is maintained on the page, which takes advantage of the dynamic language characteristics of Groovy to complete system updates and upgrades without the user's awareness, solving the problem of poor system availability and stability caused by the need to redeploy after code modification.

[0028] Specifically, the communication information includes the communication address and port, which are used to bind the communication mode in the communication template to various operation instructions of the IoT device. For example, the access control device of manufacturer 1 uses the HTTP protocol for interaction, and the HTTP communication address and port of manufacturer 1 are set, and the POST method of the HTTP communication template is bound to the door opening operation command of the access control device, and the GET method of the HTTP model template is bound to the communication record query operation command of the access control device.

[0029] Specifically, the format of the input parameter template corresponding to the operation instruction depends on the specific situation of the IoT device. The front-end page only needs to provide an input box, and no specific format verification is required. Because the interaction parameter formats of various types of IoT devices from different manufacturers are different, in order to allow the business module to use the same business parameters to call various IoT devices without difference, it is necessary to format the business parameters passed by the business module into the real parameter format of each device according to the input parameter module. For example, for the "remote door opening" operation command, the business parameters passed by the business module to the adapter module are (JSON format): { "deviceId": "xxxx", / / device ID "tagId": "xxxx" / / device tag } The business parameters of the "remote door opening" operation command of manufacturer 1 only require the device identifier (parameter name is DeviceNo) in the JSON format. Then the parameter input template is defined as: { "deviceNo":"${deviceId}" } The "remote door opening" operation command of manufacturer 2 requires the device identifier (parameter name is deviceNum) and device tag (tagId) in XML format, so the input parameter template is defined as: <root> <devicenum> ${deviceId}< / devicenum> <tagid> ${tagId}< / tagid> < / root> In the input parameter template, ${} is a parameter placeholder. When mapping, it will be replaced by the business parameter value passed by the business module. In this way, you only need to define the input parameter template for each operation command of each manufacturer's device, and the business module can interact with the IoT device without difference. The business module does not need to pass parameters in different formats according to different types of IoT devices from different manufacturers, which greatly improves the maintainability of the business module.

[0030] Specifically, since the return results of each type of IoT device from each manufacturer are different, in order to enable the business module to receive the return results of each type of IoT device from each manufacturer without difference, an output parameter template is defined for each operation instruction of each type of IoT device from each manufacturer. For example, for the "remote door opening" operation command, the return result format received by the business module is: { "code":"", "msg":"" } The return result format of the "remote door opening" operation command of manufacturer 1 is: { "result":"0", "msg":"Operation successful"} The return result format of the "remote door opening" operation command of manufacturer 2 is: { "code":"0", "message":"success" } The parameter template needs to be defined for the "remote door opening" operation command of manufacturer 1 as follows: { "code":"${result}", "msg":"${msg}" } The parameter template needs to be defined for the "remote door opening" operation command of manufacturer 2 as follows: { "code":"${code}", "msg":"${message}" } In the output parameter template, ${} is a parameter placeholder, which will be replaced by the specific corresponding value of the return result of the IoT device during mapping. In this way, the return result format of various types of IoT devices from different manufacturers is the same for the business module. There is no need to write a set of parsing codes for the return results of various types of IoT devices from different manufacturers, which greatly improves the maintainability of the system.

[0031] The parameter mapping unit is used to map the business parameters sent by the business module to the input parameter template corresponding to the operation instruction of the Internet of Things device, and based on the mapped input parameter template, the business module can make indiscriminate calls to various types of Internet of Things devices from various manufacturers; and after receiving the return result of the Internet of Things device, map the return result to the output parameter template corresponding to the operation instruction of the Internet of Things device, and based on the mapped output parameter template, the business module can receive the return result of various types of Internet of Things devices from various manufacturers indiscriminately.

[0032] Specifically, the mapping principles of the input parameter template and the output parameter template include: The JAVA regular matching mechanism is used to map and replace the parameter placeholders of the input parameter template with the business parameters sent by the business module; specifically, for business parameters in JSON format, the string in the parameter placeholder of the input parameter template corresponds to the key in the business parameter in JSON format. The JAVA regular matching method is used to extract the value corresponding to the key in the business parameter and replace it with the parameter placeholder of the input parameter template to obtain the mapped input parameter template.

[0033] Utilize the JAVA regular matching mechanism to replace the parameter placeholder mapping of the output template with the return result of the IoT device.

[0034] The communication template execution unit is used to realize the interaction with the IoT device by dynamically executing the communication method in the communication template corresponding to the IoT device, and after receiving the result returned by the IoT device, the returned result is fed back to the parameter mapping unit. Specifically, the communication template execution unit first uses the Java reflection mechanism to instantiate the groovy object defined by the communication template, and then interacts with the IoT device by executing the corresponding communication method in the communication template through grooy.

[0035] Furthermore, the adaptation module also includes a state conversion unit, which converts the multi-field return results of various types of IoT devices from various manufacturers into fixed-field status codes by maintaining a state conversion template based on an array format, and feeds the fixed-field status codes back to the business module, so as to keep the status codes received by the business module consistent with the status codes of various types of IoT devices from various manufacturers. The state conversion template is stored in the information storage and query unit. Specifically, if the IoT device returns 100 to represent success, it can be converted to 1 through the state conversion template and then returned to the business module through the unified interface of the adaptation module. The state conversion template is defined as follows: [{ "sourceKey":"code" "sourceValue":"100" "targetValue":"1" }] Among them, the state conversion template can define dynamic conversion of multiple fields, sourceKey is the name of the field to be converted, sourceValue is the original field value, and targetValue is the converted value.

[0036] In one embodiment, Figure 3 As shown, a method for dynamic adaptation of an Internet of Things device is provided, which is applied to the above-mentioned dynamic adaptation system for an Internet of Things device, and the method comprises the following steps: Before interaction, the information storage and query unit in the adaptation module configures and maintains corresponding operation instructions, communication templates written in groovy language, communication information of each manufacturer, and input and output templates corresponding to the operation instructions for each type of IoT device of each manufacturer, and sends all operation instructions to the business module; When interacting, according to several sub-modules in the business module, the unified interface of the adapter module is called, the operation instructions and related parameters corresponding to the IoT device are sent to the adapter module, and the return results of the IoT device forwarded by the adapter module are received. Based on the adapter module, the business module and various types of IoT devices of various manufacturers are adapted and interacted in the same way; Among them, based on the adaptation module, the business module can be adapted and interacted with various types of IoT devices from various manufacturers without any difference, including: According to the information storage and query unit in the adaptation module, the operation instructions and related parameters sent by the business module are obtained, and according to the operation instructions and related parameters, the communication template, communication information and input parameter template and output parameter template corresponding to the IoT device are queried; wherein the related parameters include the manufacturer code, device type and business parameters of the IoT device; When the communication information exists, the service parameters sent by the service module are mapped to the input parameter template corresponding to the operation instruction of the IoT device according to the parameter mapping unit in the adaptation module, and the service module is enabled to call various types of IoT devices of various manufacturers without differentiation based on the mapped input parameter template; Then, according to the communication template execution unit in the adaptation module, the interaction with the IoT device is realized by dynamically executing the communication mode in the communication template corresponding to the IoT device, and after receiving the result returned by the IoT device, the returned result is fed back to the parameter mapping unit; The return result is further mapped to the output parameter template corresponding to the operation instruction of the IoT device according to the parameter mapping unit. Based on the mapped output parameter template, the business module is enabled to receive the return results of various types of IoT devices from various manufacturers without distinction. After receiving the return result, the business module implements the non-differential adaptation and interaction between the business module and various types of IoT devices from various manufacturers according to the response processing logic of the return result.

[0037] In one embodiment, before the business module receives the returned result, the method further includes: According to the state conversion unit in the adaptation module, a state conversion template based on the array format is maintained, and the multi-field return results of various types of IoT devices from various manufacturers are converted into status codes of fixed fields using the state conversion template. The status codes of fixed fields are fed back to the business module to keep the status codes received by the business module consistent with the status codes of various types of IoT devices from various manufacturers.
