In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Example one
In the following, a method for synchronizing device information provided in an embodiment of the present application is described, referring to fig. 1, where the method includes:
step S101, periodically checking the target connection state of the master device and the slave device.
In step S101, the master device refers to a device that can transmit a command to control the slave device. The slave device is a device that receives a command sent by the master device and then performs a corresponding operation according to the command sent by the master device. It should be noted that the slave device may include at least one slave device. The number of slave devices can be selected by the user according to actual conditions, and the application is not specifically limited herein. It should be understood that the master and slave devices may or may not be the same type of device. The present application is not specifically limited herein.
It should be noted that, when the master device and the slave device are the same type of device (for example, both the master device and the slave device are a sweeper or a curtain), which device is the master device and which device is the slave device is opposite between the two devices. For example, at time a, device a is set as the master and device b is set as the slave. At time B, device a is set as the slave and device B is set as the master. When the master device and the slave device are the same type of device, which device is set as the master device and which device is set as the slave device, and the user may select or set the devices according to the actual situation, which is not specifically limited herein.
When a user sets one device as a master device and at least one other device as a slave device, the master device may periodically check a target connection state between the master device and the slave device.
And step S102, if the target connection state is the unconnected state, the master device establishes connection with the slave device.
In step S102, if the target connection state is an unconnected state, the master device establishes a connection with the slave device.
In some embodiments, the master device establishing a connection with the slave device includes: the master device sends a connection request to the slave device; and if receiving second target reply information returned by the slave equipment, judging that the connection between the master equipment and the slave equipment is successful.
In this embodiment, when the master device needs to establish a connection with the slave device, the master device may send a connection request to the slave device, and then periodically check whether the second target reply information returned by the slave device is received. After the slave device receives the connection request sent by the master device, if the slave device is successfully connected with the master device, the second target reply information is sent to the master device according to the connection request. And if the master device receives the second target reply message, the master device and the slave device are successfully connected. It should be noted that the content of the second target reply message may be set by the user according to the actual situation, and the application is not specifically limited herein.
In other embodiments, if a second target reply message returned from the device is not received, whether a preset event exists is detected; and if the preset event exists, returning to the execution of the main equipment to send the connection request to the slave equipment.
When the master device does not receive the second target reply information returned by the slave device, the master device and the slave device may still be in the process of connecting, and the master device and the slave device may also fail to connect. If the master device directly resends the connection request to the slave device when the master device does not receive the second target reply message returned by the slave device and the master device and the slave device are still in the connection process, more time is consumed for the connection of the master device and the slave device.
Therefore, when the master device does not receive the second target reply message returned by the slave device, the master device first detects whether a preset event exists, if the preset event exists, the connection between the master device and the slave device fails, and at this time, the master device returns to execute sending a connection request to the slave device. If the preset event does not exist, the master device and the slave device are still in the connection process, and at this time, the master device returns to execute the periodic check whether the second target reply information returned by the slave device is received.
Therefore, in this embodiment, when the master device does not receive the second target reply message returned by the slave device, it is checked whether a preset event exists first, and if the preset event exists, the master device returns to execute sending the connection request to the slave device, thereby reducing the connection time between the master device and the slave device.
It should be understood that the preset event may include an event that interrupts the connection between the master device and the slave device (e.g., some devices establish a connection with the master device that would result in the master device being disconnected from the slave device), a connection time between the master device and the slave device exceeding a preset time, and the like. The preset event user can select or set according to the actual situation, and the application is not limited herein.
In other embodiments, the master device sending a connection request to the slave device includes: obtaining reconnection times; and if the reconnection times are less than or equal to the preset times, the master device sends a connection request to the slave device after a first preset time interval, and the reconnection times are added by 1.
In this embodiment, when sending a connection request to a slave device, the number of reconnection times is obtained first. And if the reconnection times are less than or equal to the preset times, the master device sends a connection request to the slave device after the first preset time interval, and adds 1 to the reconnection times.
In other embodiments, if the reconnection number is greater than the preset number, the master device performs a preset error handling operation.
When the reconnection times are more than the preset times, the connection between the master device and the slave device is possibly wrong. Therefore, when the number of reconnection times is greater than the preset number, the master device performs a preset error handling operation. It should be noted that the preset error handling operation can be set by the user according to actual situations. Such as resetting the host system or initializing connection parameters, etc. The present application is not limited thereto.
Step S103, after establishing connection with the slave device, the master device transmits the target command to the slave device.
In step S103, the master device may transmit the target command to the slave device after the master device establishes a connection with the slave device. It should be noted that, the manner of sending the target command to the master device may be set by the user according to actual situations. For example, the master device may send the target command to the slave device in a message queue. The present application is not limited thereto.
In some embodiments, the master device sends the target command to the slave device, including: determining a target difference value according to the timestamp of the current time and a target timestamp, wherein the target timestamp is the timestamp corresponding to the time of receiving the first target reply information last time; and if the target difference value is larger than the preset threshold value, the master device sends a target command to the slave device.
In this embodiment, the master device periodically sends a target command to the slave device. And when the primary equipment receives the first target reply information every time, updating the timestamp corresponding to the received first target reply information. And then determining a target difference value according to the timestamp of the current time and the target timestamp, wherein the target timestamp is the timestamp corresponding to the time of receiving the first target reply information last time. If the target difference is greater than the preset threshold, it indicates that the master device needs to acquire the device information of the slave device at the current time. At this time, the master device transmits a target command to the slave device.
In other embodiments, the master device sends the target command to the slave device, including: when the master device receives the trigger signal, a target command is sent to the slave device.
In this embodiment, when the master device receives the trigger signal, the master device transmits the target command to the slave device. It should be noted that the trigger signal may be sent from the control end to the master device (the control end may be an application program or an applet). Or the user can directly operate the main device, and the main device receives the trigger signal. The present application is not limited thereto.
Step S104, the master device receives the first target reply information, and updates the device information of the slave device according to the first target reply information, wherein the first target reply information is information sent by the slave device in response to the target command.
In step S104, after the master device sends the target command to the slave device, the slave device sends the first target reply message to the master device according to the target command, and the master device thus receives the first target reply message. After the master device receives the first target reply message sent by the slave device, the master device can update the device information of the slave device stored in the master device according to the first target reply message, so that the master device can synchronize with the current device information of the slave device.
The target command is a command to acquire device information of the slave device. The first target reply message is the device information of the slave device. For example, if the target command is a command for acquiring the working state of the slave device, the first target reply message is the current working state information of the slave device. The device information of the slave device includes power information, operation state information, sensor data of the slave device, current location information of the slave device, and the like.
It should be noted that, when the master device does not receive the first target reply message after the second preset time interval, it is indicated that a problem occurs in the connection between the master device and the slave device. At this time, the master device returns to perform establishment of a connection with the slave device.
In other embodiments, when the slave device detects that the device information of the slave device changes, the slave device may also actively send the changed device information to the master device.
In summary, the present application provides a device information synchronization method, which first periodically checks a target connection state between a master device and a slave device. And if the target connection state is the unconnected state, the master device establishes connection with the slave device. After establishing a connection with the slave device, the master device sends a target command to the slave device. And then the master device receives the first target reply information, and updates the device information of the slave device according to the first target reply information, wherein the first target reply information is the information sent by the slave device in response to the target command. Since in the present application, the master device can periodically check the target connection state of the master device and the slave device. When the target connection state is an unconnected state, the master device establishes a connection with the slave device, so that a long connection is maintained between the master device and the slave device. Since the master device maintains a long connection with the slave device, it can directly transmit when the master device needs to transmit a target command to the slave device, so that the master device can quickly synchronize the device information of the slave device.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
