Before describing the multi-device management method provided by the embodiments of the present application, first, an exemplary description of related concepts such as the device management network, central device, first device, etc. involved in the embodiments of the present application is provided.

Device management network is a network constructed by multiple online devices establishing communication connections through multicast, Bluetooth, WIFI, etc. The online devices in the device management network can be divided into central devices, first devices, second devices and third devices according to different functions or connection methods, among which:

The central device, as the central node of the device management network, has one and only one. It uniformly manages all online devices in the device management network, including the collection of device information, device status updates and notifications, etc. The central device will collect the information of each device. The device information is summarized and stored in a device information table, and the device information table is sent to the first device in the device management network for storage.

It should be noted that when the central device goes offline or is forced to go offline, such as when a fault occurs, the communication connection between the device management network built based on the central device no longer exists, and online devices cannot communicate with each other. After the central device is installed, the device management network is constructed by the newly determined central device to realize communication management between online devices.

The first device is an ordinary node connected to the central device in the device management network. The number is not limited. It receives the device information table sent by the central device and stores it. After the first device searches for the central device or the central device goes offline, the first device determines whether to set itself as the central device through the parameters in the device information table. Device management network with it as the central node. After it is determined that the first device sets itself as the central device, the first device as the central node is called the central device in the device management network, and is distinguished from the remaining first devices, and the first device is established as the central node. device management network. The first device manages its own auxiliary devices with its own information. When the device information of the first device changes, such as when the first device goes offline or an auxiliary device is added, it sends information to the central device and notifies the device management network through the central device. other equipment in.

The second device is an accessory device of the central device, and communicates with the central device through a standard protocol.

The third device is an accessory device of the first device, and communicates with the first device through a standard protocol.

Among them, the first device and the central device are devices that can be developed twice, such as a cash register equipped with Android system. Customized application development can be carried out on the cash register. After the cash register is turned on, the customized application will automatically run. The first device and the central device can exchange information through the device management network, thereby achieving management and control of multiple devices.

The second device and the third device are devices that cannot be developed twice, such as Bluetooth/network/USB printers. These devices have a standard communication protocol for external use, such as thermal printers, which are all compliant with the ESC/POS protocol. This type of device cannot carry out customized application development, and all standard applications provided by the manufacturer are run when it is turned on. Except for the accessory devices that communicate directly with the central device, other accessory devices cannot interact with the central device in the device management network and need to do so through their owners. For example, the owner of the accessory device completes the collection and collection of information about the accessory device. Information exchange.

The following is an exemplary description of the multi-device management method provided by this application through specific embodiments.

Please refer to Figure 1, which is a schematic flow chart of a multi-device management method provided by an embodiment of the present application.

Step S101: The first device determines the online status of the central device.

In this embodiment of the present application, the currently running device management network is the first device management network, and any device in the first device management network detects the online status of the central device in real time or regularly, such as the first device broadcasting a predetermined signal, When the first device receives the signal fed back by the central device regarding the predetermined signal, it can confirm that the current online status of the central device is online; when the central device fails or goes offline, the first device fails to receive the scheduled signal from the central device. The signal fed back by the scheduled signal can confirm that the current online status of the central device is disconnected or offline.

Step S102: When the first device determines that the central device is not online, the first device obtains central device reset parameters.

In this embodiment of the present application, the central device reset parameters are the performance parameters of each device in the device information table stored in the first device, including first parameters and second parameters, where the first parameter is the Performance parameters of the first device, and the second parameters are performance parameters of other devices except the first device.

Here, the performance parameters of each device include but are not limited to CPU frequency, number, memory size, available memory size, and available disk size.

Step S103: The first device determines whether to set itself as the central device according to the central device reset parameter.

In this embodiment of the present application, the first device compares the performance parameters corresponding to each device in the device information table or the performance scores corresponding to each device calculated based on the performance parameters, and determines whether the performance parameters or performance scores corresponding to the first device are The central device resetting condition is met, thereby determining whether to set the first device as the central device.

The central device reset condition is that the performance parameter or performance score corresponding to the device is the largest performance parameter or performance score in the device information table.

It should be noted that when performance parameters are used as the central device reset parameters, any one or a combination of several performance parameters can be specified. When the central device reset parameters are to specify several performance parameters, the priority of each performance parameter is used. Determine whether central device reset conditions are met.

In some embodiments of the present application, since the device information table also contains the performance parameters of the original central device, in order to avoid repeated calculations or causing the problem of being unable to accurately determine the central device, the first device is determined as the central device when determining whether to set the first device as the central device. , the performance parameter needs to be eliminated, and then it is determined whether to set the first device as the central device based on the remaining performance parameters.

Please refer to Figure 2. Figure 2 is a specific flow diagram of a central device setting method provided by an embodiment of the present application. The details are as follows:

Step S201: The first device calculates the performance score corresponding to each device according to the first parameter and the second parameter.

In the embodiment of the present application, the performance score corresponding to each device is calculated according to the performance parameters corresponding to each device, or according to the performance parameters corresponding to each device and the weight corresponding to each performance parameter.

Step S202: When the performance score of the first device meets the central device resetting condition, the first device sets itself as the central device.

In the embodiment of the present application, when the performance score corresponding to the first device is the highest one among all calculated performance scores, it is determined that the performance score of the first device meets the central device reset condition, otherwise, the performance of the first device is determined Score is not eligible for central device reset.

After setting the first device as the central device, the central device obtains the broadcast information of the online device and establishes at least one communication link according to the communication method it supports, so that the reset central device can establish communication connections with all online devices. Build a new device management network.

It should be noted that the broadcast information includes but is not limited to information such as device identification, communication methods supported by the device, and whether the device is a central device. The device ID is the unique identifier of the device and can be replaced by the device's serial number. The communication methods supported by the device include LAN address, WIFI P2P link, Bluetooth MAC address, etc.

Step S203: When the performance score of the first device does not meet the central device reset condition, the first device joins a third device management network. The third device management network is configured for other than the first device. A device management network built with any device.

In this embodiment of the present application, when the first device joins the third device management network, it sends device information to the central device in the third device management network, triggering the central device in the third device management network to update the device information table. .

It should be noted that when the first device serves as a central device to build a new device management network, the first device updates its stored device information table based on the device information sent by each device, and sends the updated device information table to Device management of individual devices in the network.

Step S104: After the first device sets itself as the central device, the first device builds a second device management network.

In this embodiment of the present application, after the first device builds a second device management network, it receives device information sent by each device in the second device management network, and updates the device based on the device information sent by each device in the second device management network. information table, and sends the updated device information table to each device in the second device network, so that each device in the second device network can obtain the latest device information table and update it.

Step S302: When the first device does not search for the central device, the first device sets itself as the central device.

In this embodiment of the present application, when the first device does not search for the central device within a predetermined time, the first device sets itself as the central device and receives broadcast information sent by other devices, thereby building a new device management network.

It should be noted that, under normal circumstances, when the first device is the first device to be powered on, or when the first device is powered on, the central device happens to be offline and a new central device has not yet been determined. , the first device cannot search for the central device, so it can directly set itself as the central device and build a device management network with it as the central node.

Step S303: When the first device searches for the central device, the first device joins the first device management network.

In this embodiment of the present application, the first device determines the online status of the central device, and when it is determined that the central device is not online, obtains the central device reset parameters; and determines whether to set itself as the central device according to the central device reset parameters. Central device; after the first device sets itself as the central device, a second device management network with the first device as the central device is constructed, thereby improving the robustness and effectiveness of multi-device management.

In a specific application scenario of this application, a cash register with Android system serves as the central device MA. When another cash register with Android system comes online as the first device MB, the first device MB uses LAN, WIFI, Bluetooth, etc. Establish a communication connection with the first device and join the device management network built with the central device MA. The first device MB sends its own device information and the device information of the accessory device to the central device. The central device updates the device according to the received device information. information table, and sends the device information table to the first device MB. The first device regularly detects the online status of the central device and determines whether the communication link with the central device MA is disconnected. When the central device MA goes offline and the communication link between the first device MB and the central device MA is disconnected, the first device Based on the device information table sent by the previous central device MA, MB obtains the central device reset parameters and determines whether to set itself as the central device. If it is determined to set itself as the central device, it builds a device management network with itself as the central device, that is, Construct a device management network with the first device MB as the central device, so that multiple online devices can still be managed after the central device of the original device management network goes offline, which improves the robustness and effectiveness of multi-device management.

In a specific embodiment of the present application, when multiple devices are online at the same time, and no device information table is stored in each device, or the device information table is empty, after the multiple devices establish communication connections, a device is randomly designated as central equipment.
