TECHNICAL FIELD
[0001] The present application relates to the field of wireless network communication, in particular to a wireless roaming switching device and a control method. BACKGROUND
[0002] In the field of wireless network communication, the movement of devices will have an uncertain impact on wireless communication. For example, when a patrol device is a mobile device, i.e., a smart mobile device, it will inevitably encounter data switching between multiple same frequency and / or different frequency access points when moving in a wireless coverage area.
[0003] During this period, the actions of searching, disconnecting, connecting, authenticating, and resuming transmission inevitably cause data delay and interruption. In particular, in scenarios where the patrol device moves at a higher speed, the switching action is too frequent, which can cause long-term data loss and seriously affect the overall communication effect. Therefore, the industry needs to design a wireless roaming switching device and a control method to solve the above technical problems. SUMMARY
[0004] The working method of the existing wireless roaming switching device is as follows: a single processing module is used, the working state of the processing module is in client mode, and a signal threshold for starting the switching action is set. The device in client mode is connected to the access point device after wireless authentication, data transmission occurs after connection, the signal threshold is detected during data transmission, and when the signal of the current connection reaches the threshold for starting the switching action, the surrounding connectable access point device is searched, the access point device is confirmed to be connectable, the current connection is disconnected, and the new access point device is connected after authentication. Data transmission occurs after connection. Further, the process is repeated to achieve the effect of roaming switching.
[0005] The scheme of the present application proposes a new technical solution (including a device and a method) to solve the problem of "easy data interruption or long-term loss" caused by single processing module roaming switching, i.e., the device is composed of multiple slave processing modules and a master processing module, and the master processing module controls the multiple slave processing modules to work in client mode and access point client comprehensive mode. That is, after the slave processing module 1 is connected to the access point device, a connection is formed, data transmission is started, and the master processing module controls the slave processing module 2 / other slave processing modules to search for new available access points in the surrounding area, and another / multiple connections are formed with the new access point device after authentication, but no data transmission occurs.
[0006] In the moving process, the communication connection quality (signal quality) of one connection and another connection is continuously detected, and when it is found that the signal quality of another connection is better than that of the one connection, under the control of the master processing module, the data to be transmitted is directly transferred to another connection, and the slave processing module 1 / other slave processing modules are controlled to search for a new access point available in the surrounding area, and form a new connection with the new access point device after authentication.

[0028] Embodiment 1 Please refer to Figures 1 to 2FIGURE 1 illustrates a control method for a wireless roaming handover device, namely, a wireless roaming handover control method, according to an embodiment of the present invention. The method is used in a wireless roaming handover device comprising at least one master processing module and several slave processing modules, each of which is wiredly connected to the master processing module.

The master processing module controls all slave processing modules to operate in access point mode, client mode, or access point-client combined mode, and controls each slave processing module, through the master processing module, to connect to devices in other access point mode or access point-client combined mode. In one embodiment, the master processing module and the slave processing modules are disposed on the same PCB board; alternatively, the master processing module and the slave processing modules are disposed on different PCB boards. In one embodiment, the master processing module and the slave processing modules are disposed in different chips; alternatively, the master processing module and the slave processing modules are integrated into the same chip. Furthermore, the control method for a wireless roaming switching device includes: S1, the main processing module controls the first slave processing module to establish a wireless connection, wirelessly connecting to a device in a first access point mode / access point client integrated mode along a preset path within a first area corresponding to the first slave processing module; the main processing module controls the second slave processing module / other slave processing modules to establish a wireless connection, wirelessly connecting to a device in a second access point mode / access point client integrated mode along the preset path within a second area corresponding to the second slave processing module / other slave processing modules; S2, monitoring the wireless connection with the device in the access point mode / access point client integrated mode along the preset path until the moving position of the device no longer belongs to the first area; S3, the first slave processing module disconnects the wireless connection with the device in the first access point mode / access point client integrated mode, the second slave processing module / other slave processing module maintains the wireless connection with the device in the second area, and the first slave processing module / other slave processing module searches for a target that meets the preset requirements as a supplementary connection.

[0033] In an embodiment, the method further comprises: S71, monitoring the mobile device moving along the preset path until the position of the mobile device does not belong to the second area and still belongs to the third area.

[0035] The technical effect of the above scheme is that the optimal connection is always maintained without simply relying on the threshold setting of the switching action initiation, and the smooth switching capability of the wireless device in the multi-access point environment is improved.
[0036] The embodiment of the application further provides a storage device which stores one or more programs which can be executed by one or more processing modules to implement the steps in the control method provided in any of the above embodiments. The storage device executes the control method, and the overall communication effect of the device during movement can be significantly improved.
[0037] To sum up, in the field of wireless network communication, the movement of the device will have an uncertain impact on wireless communication. For example, when the inspection device is a smart mobile device with a mobile capability, it will inevitably encounter data switching between multiple same frequency and / or different frequency access points when moving in the wireless coverage area.
