Description

Electronic device, wireless networking system, device, control method thereof and storage device

Technical field

The present invention relates to a wireless networking technology, and in particular, to an electronic device, a wireless networking system, a device, a control method thereof, and a storage device.

Background technique

In this era of intelligence and network finalization, the establishment of wireless local area networks in a certain space (such as homes, enterprises, etc.) has been well received by people. Existing wireless communication systems mostly use relay, or point-to-point, or point-to-multipoint methods for wireless cascade networking.

The principle of the relay networking is that when the signal of the device at point a reaches the device at point c, the device at point b needs to be added as a relay, that is, the point b of a certain time slice is the receiving state with respect to point a, and the point b of the other time slice is relatively Point c is the transmitting state, so that the device at point b receives the information of point a (or point c) in the first time slice according to a certain timing rule, and forwards the information to point c (or point a) in the next time slice to constitute the device. The MCU chip, no matter how much, uses the above transmission information process. For example, MESH (Wireless Grid Network) technology is built on the basis of relay.

However, the disadvantages of relay networking are:

1. When transmitting data in the relay mode, the device switches back and forth between receiving and transmitting information according to the time-sharing mode of operation, and the response speed is slow;

2. The relay mode adopts time-sharing work, and its forwarding characteristics reduce the data transmission rate by 50%. If it is forwarded more than 2 times, the transmission rate is basically the minimum bandwidth;

3. The equipment working in the relay mode must work at the same frequency and cannot overcome the problem of co-channel interference, resulting in increased interference and further affecting the communication bandwidth;

4. The speciality of the MESH protocol is only used as a link device and cannot communicate with ordinary 802.11 wireless devices. If necessary, the standard access device must be plugged in and the cost increases.

The point-to-point working principle is that the identity between the a device and the b device is the same, and the same configuration is selected to support point-to-point communication.

The disadvantage of point-to-point communication is that it can only support a limited number of devices and cannot form a communication network.

The point-to-multipoint communication principle is a general-purpose basic wireless network architecture, usually an AP (Access Point) + a multi-point STA ((Station)). All STA devices are associated with the AP to form a communication network.

Disadvantages of point-to-multipoint:

Such a communication network supports the construction of a local wireless network, has a limited support distance, and does not have the capability of networking of two or more APs.

In step S31, the peripheral wireless signal is detected by the processing module operating in the terminal mode, and the wireless device list is available according to the detected wireless signal. For example, the main processing module can set a certain threshold when the wireless intelligent group When the signal strength of the network device is greater than the threshold, it is determined that the device corresponding to the wireless signal is an available device, and is added to the wireless device list, and the threshold may also be adjusted according to requirements.

Among them, the wireless connection quality is optimal, including the best signal-to-noise ratio, the strongest signal, the least peripheral interference, and the least connected equipment, which enables the wireless device to transmit data at the most stable and fastest speed.

In order to facilitate the understanding of the phase monitoring WIFI intelligent search connection mechanism, the present invention continues to use wireless intelligent networking devices for wireless devices, the main processing module is the main MCU, the MCU1 is the slave processing module working in the access point mode, and the MCU2 works at the terminal. The mode slave processing module is taken as an example for description: the local master MCU controls the local MCU2 to search for the MCU1 of the peripherally connectable wireless intelligent networking device, and forms a list of available wireless devices; after that, the local master MCU is configured according to its storage. The algorithm selects the optimal connection quality from the processing module and makes the local MCU2 establish a wireless connection with it; then the local MCU determines whether the wireless connection is successful. If the connection is not successful, the local MCU controls the local MCU2 to select the signal strength. Good external MCU1, and make the local MCU2 establish a wireless connection with it; if the connection is successful, it can enter the loop avoidance mechanism.

After the slave module of the terminal mode establishes a connection with the access point mode of the other wireless device from the processing module, the connection mode of the adjacent WIFI wireless intelligent self-organizing network device can be implemented as a loop avoidance mechanism, as shown in FIG. In step S20 or step S32, the control method may further include:

S33. Send a broadcast packet by the slave processing module working in the terminal mode.

S34. The slave processing module receives a broadcast packet sent by another wireless device, and determines, by the main processing module, whether it is a local broadcast packet.

S35. When the broadcast packet is a local broadcast packet, disconnect the slave processing module from wireless with the other wireless device, and re-search for the remaining wireless devices to establish a wireless connection.

In this embodiment, the broadcast packet is sent to the connected wireless intelligent networking device in real time through the terminal mode slave processing module, and the broadcast packet sent by the processing module in the terminal mode passes through one or more wireless intelligent networking devices connected thereto. Returning to the slave processing module, that is, receiving the broadcast packet sent by the processing module, it is determined that the current network connection has a connection loop, that is, there are multiple wireless intelligent networking devices in the current network. The connection forms a loop condition, which prevents the correct transmission of data.

The module sends the received broadcast packet to the slave processing module in the access point mode. If the slave module in the access point mode cannot receive the broadcast packet, it determines that the current wired connection is faulty and cannot transmit data. Then, the connection disconnection information is sent to the slave mode of the terminal mode, so that it can open the wireless network port according to the information.
