Description

Terminal equipment monitoring method, system and subscription publishing device

technical field

The present invention relates to the field of communication technologies, and in particular to a terminal device monitoring method, system and subscription publishing device.

Background technique

The Universal Serial Bus (USB) mobile terminal refers to a mobile communication terminal with a USB interface, such as a smart phone with a USB interface, a wireless data card, etc. The specific USB interface types include a virtual USB serial port, a virtual USB modem (Modem ) port or virtual USB Ethernet port and so on. With the substantial improvement of the processing capability and hardware standard configuration of mobile terminals, some fixed broadband services are gradually implemented on mobile terminals. For example, some mobile terminals already have a routing function. Other functions such as taking pictures, video cameras, global positioning systems (GPS), and radios (FM) have become very common functions.

Although mobile terminals have become very popular, PCs still occupy a dominant position, and it will take a long time before PCs are eliminated. Therefore, mobile terminals and PCs still have to coexist for a long time. Before the monopoly of cloud computing, there is still a lot of interaction between them, such as data sharing, wireless modem, wireless routing, etc. Mobile terminal PC suite, user management (CM) management software (hereinafter collectively referred to as user interface (UI) management software), etc. to facilitate the use of various functions of the mobile terminal. All these UI management software need to implement a basic function that is USB device management, mainly to allow the UI management software to obtain device insertion and removal information in a timely manner. At present, the device management methods provided by each UI management software are different. For example, when using Qualcomm’s USB driver, the registry will be operated during the driver loading/unloading process to indicate the device’s plugging/unplugging status, so this class The device can monitor the device through the corresponding registry. There are other methods and so on. In addition, the device monitoring interfaces provided by different operating systems are also different. For example, Windows provides broadcast messages for device plugging and unplugging information for each service or window, but Linux does not provide such broadcast messages because it regards devices as files. However, information such as device plugging and power supply changes can only be monitored through monitoring files.

In addition, some special users (such as test users, etc.) need to perform batch operations, that is, they need to operate on multiple devices.

In addition, most of the information provided by the current platform to UI management software is fixed. If more information is provided, the amount of communication data will increase, and some of them may not be of interest to UI management software. Therefore, if the UI management software can subscribe to the information it is interested in, it can greatly reduce the amount of unnecessary communication data, and at the same time enhance the scalability of the UI management software.

The present invention provides a subscription publishing device, which includes:

The receiving subscription module is used to receive the subscription information sent by the user interface (UI) management device, the subscription information includes the information of the subscribed terminal equipment; and

A publishing module, configured to obtain monitoring information of the terminal device from the device management device according to the subscription information, and send the monitoring information of the terminal device to the UI management device.

In addition, the device further includes: a saving module, configured to save the list information of the UI management device that sent the subscription information after the subscription receiving module receives the subscription information sent by the UI management device, in the list information storing the corresponding relationship between the UI management device and the terminal equipment it subscribes to;

The publishing module is used to identify the UI management device for subscribing to the monitoring information of the terminal device according to the corresponding relationship in the list information saved by the saving module, and send the The monitoring information of the terminal equipment is sent to the UI management device subscribed to the monitoring information.

The above subscription publishing device can subscribe interested information for users, thereby reducing the amount of unnecessary communication data.

The present invention provides a monitoring system for terminal equipment, the system includes the above subscription publishing device, and also includes a user interface (UI) management device and a device management device, wherein:

The UI management device is configured to send subscription information to the subscription publishing device and receive monitoring information sent by the subscription publishing device;

The device management device is configured to obtain monitoring information of the terminal device.

Specifically, the device management apparatus is configured to obtain monitoring information of the terminal device through broadcast messages of device plug-in changes and power supply changes or kernel notification events.

In addition, the UI management device is also used for initialization; the UI management device for initialization is used to call a dynamic link library (DLL) to initialize all information in the shared segment set in the DLL.

As shown in Figure 1, it is a schematic structural diagram of an embodiment of the monitoring system of the present invention. The system includes a subscription publishing device 11 and a device management device 12, wherein the device management device further includes a device monitoring module, a device status maintenance module, a device control module, Task scheduling center and I/O data cache module, wherein:

The device management device is mainly responsible for providing unified device management to the UI management device. It mainly involves the opening, closing, reading and writing operations of the device and the maintenance of the device status. At the same time, for unified management, the device status and device port information must be shared so that all UI management devices can access it.

The subscription publishing device is mainly responsible for saving and maintaining the information list of the subscription UI, and at the same time provides two communication methods for the subscription UI: individual communication and broadcast communication. The system can independently choose the message publishing method according to specific needs.

The above subscription publishing apparatus is realized based on the publish/subscribe (ie, Publish/Subscribe) mode. The publish/subscribe design pattern is also known as the subject/observer design pattern: that is, the subscriber registers an event with the publisher, and when the publisher has a behavior that the subscriber is interested in, it will actively notify the subscriber.

The device monitoring module is used to implement unified monitoring of all USB virtual ports in one way.

Among them, on the Windows platform: the device monitoring module is mainly responsible for monitoring changes such as device plugging and power status; its realization is to use the operating system to provide broadcast messages (WM_DEVICECHANGE) and The power supply change broadcast message (WM_POWERBROADCAST), through the above broadcast message, can timely and uniformly capture all USB device plugging and unplugging and power status and other device change information.

Specifically, to capture the broadcast message provided by the above operating system, the object is either a service or a window. In the present invention, only the window is selected as an embodiment for illustration. Since the system is a platform and does not need the physical window to be displayed, the window needs to be set as hidden.

Further, the device name displayed in the device manager can be obtained from the parameters in the captured broadcast message by using this hidden window, which is the unique identifier of the device in the system, even if two devices of the same type are plugged in On the same PC, the device name is also different, because the system will automatically add a serial number at the end to distinguish different instances of the same device; finally, the device name plus other auxiliary information will be broadcast to the subscribed UI.

Under the Linux platform: the realization of the device monitoring module is mainly completed by the daemon process of the user device (udev). When the device is powered on or powered off, the linux kernel will generate a notification event and provide it to daemon processes such as udev after monitoring. Its effect is equivalent to the system broadcast message of device plugging and unplugging obtained under Windows.

In addition, since this system is provided in the form of a dynamic library (Dll) for calling by the UI management device. Under normal circumstances, set the variable as a global variable and put it in the BSS (Block Started by Symbol) segment to achieve the purpose of data sharing. However, when each UI management device calls the dynamic library, it is necessary to copy the BSS section of the dynamic library, so the purpose of data sharing cannot be achieved by using global variables. For this reason, in the embodiment of the present invention, a preprocessing instruction #pragma data_seg is used to set a shared segment, and all information in the shared segment is initialized to achieve the purpose of sharing in the dynamic library.

The above-mentioned monitoring system makes the device monitoring module universal by using the system broadcast message under the Windows operating system or the kernel notification event under the Linux operating system, which can be applied to monitor the USB virtual devices of various manufacturers, and realize the unified monitoring of all USB devices. Management, which is applicable to individual users and batch users (including test users), and prevents device monopoly, improving system stability under power switching. In addition, the Publish/Subscribe (i.e. Publish/Subscribe) mode is used to provide a communication method with separate communication and broadcast communication between the equipment management device and the UI management device, so that the system can use the UI management device on the current PC machine Various scenarios encountered in the process provide common, unified, and scalable functions such as device monitoring, device management, and information interaction.

As shown in Figure 2, it is the relationship diagram of the class of the subscription/publishing mode of the embodiment of the present invention. On the one hand, the subscription base class and the publishing base class of the subscription/publishing mode are in the same file, that is, the subscription base class and the publishing base class can be Realize data sharing in a file, so that the information list of subscribers can be easily managed and maintained by the publishing base class. On the other hand, the mutual invocation of methods in the subscription base class and the publishing base class is implemented in the same file, which is equivalent to the communication between subscription and publication. Based on the above two aspects, it is convenient to implement two communication modes: separate communication and broadcast between the client (subscription) and the server (publish).

Among them, the subscription base class provides subscription/unsubscription functions, registration functions to the publishing base class, and functions for receiving message notifications. The publishing base class provides functions to implement subscription/unsubscription user management, handle subscription registration functions, and provide individual communication and broadcast functions to subscribers.

In addition, inherit from the subscription base class of the above file, and overload the notification function of receiving messages in the base class. The specific content of the notification can be obtained from the parameters of the overloaded function. Inherit from the publishing base class of the above file, and overload the processing registration function in the publishing base class. The specific content of the registration notification can be obtained from the parameters of the overloaded function. Message notification function and broadcast function are called according to the actual situation.
