Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In order to better understand the above technical solution, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
First embodiment
In this embodiment, in the mounting method of the internet of things device according to the present invention, the functional modules of the application system are shown in fig. 1, and mainly include three modules, namely, a device enumeration thread module, a hardware abstraction layer module, and a hardware interface service layer module, where device enumeration refers to a process of acquiring device basic information through a device instruction, determining a device type, and loading a suitable driver. Device enumeration threads refer to specialized threads in computer systems that handle device enumeration processes, in USB (Universal Serial Bus ) systems when a USB device is connected to a USB host, the host needs to identify the device and load the appropriate driver through the enumeration process. The device enumeration thread module belongs to a kernel mode of a built-in system, can read a device protocol library, and simultaneously reads the device information of the third-party Internet of things at fixed time through a hardware interface service layer, and sends out a software interrupt signal after the device information is successfully read, wherein the interrupt signal carries the device basic information. The hardware abstraction layer can receive the device basic information carried in the interrupt signal after receiving the interrupt signal sent by the device enumeration thread, read the corresponding device object model information according to the device protocol information corresponding to the device basic information reading device protocol library, finally initialize the device and verify whether the device is legal according to the device protocol, create the device number (primary device number and secondary device number) after the verification is completed, and mount the device under the user mode "/dev" directory. The hardware interface service layer provides basic device communication protocols such as rs485, modbusRTU, http, mqtt, tcp, udp, sip, rtsp and the like.
Specifically, referring to fig. 2, the method for mounting the internet of things device of the present invention includes the steps of:
step S10, when an interrupt signal of equipment enumeration corresponding to equipment enumeration of the equipment of the Internet of things in an equipment enumeration thread is received, acquiring equipment basic information carried by the interrupt signal;
An internet of things device refers to a non-standard computing device capable of connecting to a network and having data transfer capabilities. In this embodiment, the internet of things device refers to a device that does not perform device enumeration or fails enumeration at the system application layer. Thus, it can be appreciated that the internet of things device that has completed device enumeration and has access to the network system is the successfully enumerated device.
When the internet of things device accesses a new network system, a corresponding device service is generally created at a system application layer, and the device application layer service enumerates devices and initializes the devices directly through a device protocol, and identifies the devices according to the corresponding protocol. Because the device enumeration process is customized, the corresponding device interface is provided by the kernel of the operating system, that is, the device protocol can only provide the application layer private interface operating device, and can not provide the standardized system call interface operating device, when the device service is down, the internet of things device can not be used continuously, and the system stability is poor.
Based on this, in order to improve system stability, in this embodiment, when an internet of things device accesses to a network system, it needs to determine, through a device enumeration thread, whether the internet of things device is a device that has completed device enumeration, so that when the internet of things device does not perform device enumeration, the mounting process of the internet of things device is performed on the hardware abstraction layer module, thereby enabling to provide a standardized device system call interface.
Specifically, when the internet of things device is not successfully enumerated, the device enumeration thread generates a device enumeration interrupt signal, wherein the interrupt signal contains device basic information of the internet of things device, such as a device sn (Serial Number), a device firmware version Number and the like, and sends the interrupt signal to the hardware abstraction layer module, so that the hardware abstraction layer module obtains the device basic information carried by the hardware abstraction layer module when receiving the interrupt signal, and then mounts the internet of things device into a user directory according to the device basic information.
It should be noted that in a computer system, an interrupt signal is a mechanism that allows a hardware device to interrupt the execution flow of a central processor when needed to obtain the attention and response of the processor.
Step S20, equipment protocol information corresponding to an equipment protocol library is read according to the equipment basic information, and the equipment of the Internet of things is initialized based on the equipment protocol information;
In this embodiment, the device protocol library includes different device protocol information of a plurality of different devices of the internet of things, where the protocols may be transmission protocols or communication protocols, and the device protocol library may be stored in a cloud platform or a local server. The equipment protocol information needed when different internet of things equipment is accessed into a computer network system is different, so that after the equipment basic information is obtained, the equipment protocol information corresponding to the equipment basic information is read from an equipment protocol library according to the equipment basic information, and the internet of things equipment is initialized and subsequently mounted according to the equipment protocol information, so that a standardized equipment calling interface can be provided, and the stability of the system is improved. In order to complete necessary information authentication processing on the internet of things device, an initialization processing is required in a connection process.
As an optional implementation manner, the device basic information may be used as a query condition, then the device protocol information corresponding to the device protocol library is read, then when an initialization process is performed, a device initialization instance corresponding to the device protocol information is determined first, and the internet of things device is initialized according to the device initialization instance. By initializing the Internet of things equipment, the efficiency of mounting the Internet of things equipment can be effectively improved.
Step S30, when the initialization of the Internet of things equipment is completed and the equipment is in a normal state, equipment threads and equipment numbers of the Internet of things equipment are created, and the Internet of things equipment is mounted to a user-state catalog.
In this embodiment, when the initialization of the internet of things device is completed, and each scheduling function of the internet of things device is normal, that is, in a normal state, it is stated that the internet of things device can be applied to a computer network system, and in order to ensure that the internet of things device can be accurately connected to an internet of things platform corresponding to the computer network system and correctly identified and managed by the platform, a device thread and a device number of the internet of things device need to be created. The device number is a unique identifier of the internet of things device and is used for distinguishing each device on the internet of things platform, and the unique identifier is a basis for device access and communication, so that the platform can accurately identify data and instructions from specific devices. The device threads are logical channels for the devices to communicate with the platform of the internet of things, and each device thread represents a connection between the device and the platform, and through the device threads, the device of the internet of things can send data to the platform and can also receive commands from the platform. And the device thread is created, so that the efficient communication between the device and the platform can be realized, and meanwhile, the device thread allows the platform to process the connection requests of a plurality of devices at the same time, thereby improving the concurrent processing capacity of the computer network system.
The user-state directory may be a "/dev" directory under which user-state programs are allowed to perform operations such as disk reading and writing, serial access, etc. Based on the above, the device protocol information of the internet of things device is built in a system kernel mode, and the user mode application service can operate and read and write the device information through a system standard calling interface. The device is enumerated, identified and mounted through the hardware abstraction layer module and the device enumeration thread, the use difficulty of the device is reduced, the application layer service is enabled to be noninductive in the use process, namely, the operation on the application layer is not needed, and a user can directly operate the internet of things device in a system calling mode, so that the stability of a computer network system is improved.
In an optional implementation manner of mounting the internet of things device to the user-state directory, when the initialization of the internet of things device is completed and the internet of things device is in a normal state, a device type of the internet of things device is determined, a primary device number and a secondary device number are allocated based on the device type, then a device driver is registered based on the primary device number and the secondary device number, and the internet of things device is mounted to the user-state directory. The registration processing of the device driver is carried out through the main device number and the secondary device number, so that the device driver can be called according to a standardized system call interface, and further the Internet of things device can be called according to the device driver, and the stability of a computer network system is improved.
According to the technical scheme disclosed by the embodiment, when the interrupt signal corresponding to the Internet of things equipment is received, the equipment basic information carried by the interrupt signal can be obtained, then the equipment protocol information for carrying out equipment initialization processing is queried by taking the equipment basic information as a query condition, finally when the initialization of the Internet of things equipment is completed and is in a normal state, the Internet of things equipment is mounted in a user state directory, based on the equipment protocol information, enumeration, identification and mounting are carried out through a hardware abstraction layer module and an equipment enumeration thread, the equipment use difficulty is reduced, the application layer service is enabled to be insensitive in the use process, namely the operation on the application layer is not needed, and a user can directly operate the Internet of things equipment in a system call mode, so that the stability of a computer network system is improved.
Second embodiment
Referring to fig. 3, according to the first embodiment, step S10 further includes:
Step S40, starting the device enumeration thread, reading the device content of a device protocol library based on the device enumeration thread, and taking the device corresponding to the device content as enumerated device;
Step S50, the access information of the equipment is polled through the hardware interface service layer at regular time;
In this embodiment, before the device enumeration of the internet of things device is performed, a device enumeration thread needs to be started first, and then device information, which is stored in a current device protocol library and is successfully enumerated, is read by the device enumeration thread, so as to determine whether the device enumeration of the internet of things device is successful or not according to the enumerated device.
After the device enumeration thread is started, the access information of the device is checked through the timing polling of the hardware interface service layer, so as to judge whether a new Internet of things device is accessed into the current network system according to the access information.
Step S60, when the equipment access information exists, equipment information corresponding to the access information is read, and when equipment corresponding to the access information is not successfully enumerated, the interrupt signal is generated and sent.
In this embodiment, as an optional implementation manner, when the device access information exists, the device information corresponding to the access information is read, and then whether the device is an enumerated device is determined. And when the equipment is not the enumerated equipment, judging that the equipment is not enumerated successfully, generating the interrupt signal corresponding to the equipment of the Internet of things, and sending the interrupt signal to a hardware abstraction layer, wherein when the equipment is not enumerated successfully, the equipment is the equipment of the Internet of things. Based on the method, the access information of the equipment is polled regularly, the equipment is used as the equipment of the Internet of things when the equipment is not enumerated successfully, and an interrupt signal is generated and sent to a hardware abstraction layer so as to initialize and mount the equipment of the Internet of things, thereby improving the stability of a computer network system. When judging whether the device is an enumerated device, a judging function can be called, and whether the device is the enumerated device is judged according to the result of function feedback.
In addition, in another alternative implementation manner, when the device access information exists, the device information corresponding to the access information is read, and then whether the device is an enumerated device is judged. And when the equipment is the enumerated equipment, judging that the equipment is enumerated successfully, skipping and executing the step of reading the equipment content of the equipment protocol library based on the equipment enumeration thread, and taking the equipment corresponding to the equipment content as the enumerated equipment. Therefore, the successfully enumerated equipment is prevented from being mounted in the user state directory, and the utilization rate of system resources is improved.
Optionally, when the device access information does not exist, the step of reading the device content of the device protocol library based on the device enumeration thread and taking the device corresponding to the device content as an enumerated device may be skipped.
In the technical scheme disclosed in this embodiment, after a device enumeration thread is started, device content in a device protocol library is acquired through the device enumeration thread, then enumerated devices in the device protocol library are determined, then whether access information of the devices exists is polled regularly through a hardware interface service layer, and when the access information of the devices exists and the devices are new access devices, interrupt signals are generated and sent to a hardware abstraction layer, so that initialization and mounting processing are performed on the internet of things devices, and stability of a computer network system is improved.
Third embodiment
Referring to fig. 4, after step S20, according to the first embodiment, the method further includes:
Step S70, determining object model information of the Internet of things equipment according to the equipment basic information, wherein the object model information comprises equipment attributes, services, events and interaction protocols;
step S80, determining the function of the object model information according to the attribute, the service, the event and the interaction protocol, and performing scheduling test based on the function;
And step S90, judging and determining that the Internet of things equipment is in a normal state when the scheduling test result is normal.
In this embodiment, in the process of determining whether the internet of things device is in a normal state, the scheduling test of the device may be performed through the object model information of the internet of things device to determine. The object model comprises the attribute, service, time, interaction protocol and the like of the equipment, so that corresponding test examples can be generated according to the information, the functions of the equipment of the Internet of things are tested, and whether the functions are normal or not is judged through the object model.
In an alternative embodiment, the function of the object model information may be determined according to the attribute, the service, the event and the interaction protocol, then a test scheduling method or a test scheduling instance may be generated based on the function, the function may be tested according to the test scheduling method or the test scheduling instance to obtain test data, then the test data may be compared with target data corresponding to the function, when the comparison result is that the device passes, a normal result of the device may be generated, and when the comparison result is that the device does not pass, an abnormal result of the device may be generated. Based on the method, whether the equipment of the Internet of things is normal or not is judged through the information of the object model of the equipment, so that the verification efficiency of the equipment of the Internet of things is improved.
