and step S106, under the condition that the data channel is the data channel used by the current data transmission, switching the data channel into a standby channel according to the available standby channel list, and performing data transmission with the target equipment through the switched standby channel.
Through the steps, the availability detection is carried out on the data channel connected with the target equipment; determining whether the data channel is a data channel used for current data transmission or not under the condition that the availability detection result of the connected data channel is unavailable; the method comprises the steps that when a data channel is used for data transmission at present, the data channel is switched to a standby channel according to an available standby channel list, the availability of the data transmission channel connected with a target device is detected in a data transmission mode between the switched standby channel and the target device, and when the data channel for data transmission is unavailable, the standby channel is switched to the standby channel, so that the purpose of ensuring the stability and the efficiency of data transmission is achieved, the technical effect of eliminating the influence of the computing capacity and signal instability of hardware equipment on the stability and the efficiency of data transmission is achieved, and the technical problems that the computing capacity of intelligent hardware equipment in the related technology is limited, and instability is possibly caused by the problem of signal difference and the like when the equipment is connected and data communication is carried out are solved.
The executing main body of the above steps may be an active device or a passive device, where the active device is a terminal device which actively searches and initiates a connection request during establishing a data connection, and the passive device is a terminal device which accepts the search of the active device and is passively connected. The target device is a device corresponding to the execution subject, and for example, when the execution subject is an active device, the target device is a passive device, and when the execution subject is a passive device, the target device is an active device.
A plurality of data channels, for example, WIFI data channels, network data channels, near field communication data channels, and the like, may be established between the execution main body and the target device. When the data channel is established, the active device may search for the target device using the channel information through the search connection module. The channel information includes data channel type, channel configuration information, connection timeout time, state detection mode, data availability detection, health threshold, channel switching algorithm threshold, and the like. When the active device searches for the device, the device uses different target device information to broadcast or directly search according to different channel types. On the passive device, the search connection module is responsible for responding after receiving the broadcast or direct search request from the active device, so as to ensure that the opposite side can acquire own device information.

And carrying out availability detection on the data channel connected with the target equipment, and carrying out different operations according to the use condition of the data channel under the condition that the data channel is determined to be unavailable.
When the data channel is a data channel used for current data transmission, it indicates that the data transmission has been hindered, and the data channel used currently needs to be replaced by another connected alternative channel, so that the quality and stability of data transmission can be ensured.
The above-mentioned alternative channels may be a plurality of data channels that are simultaneously established when establishing the data connection between the execution main body and the target device. The alternative channel can transmit data through a data transmission channel and a data transmission mode corresponding to the data channel.
The alternative channels are arranged in an alternative channel list, and are sorted according to the priorities of the alternative channels, and when the alternative channels are replaced, the alternative channels with high priorities are preferentially selected.
Optionally, the detecting availability of the data channel to which the target device is connected includes at least one of: detecting the health state of the connectivity of the data channel; detecting the data availability of the data channel; the hardware state of the data channel is detected.
The data transmission of the data channel may be affected by various factors, and therefore, it is necessary to detect the various factors to determine whether the data transmission of the data channel is affected, so as to cause the problems of unstable data transmission and low efficiency.
The detection can be used for detecting the health state of the connectivity of the channel, the data availability of the data channel, the hardware state of the data channel and other dimensions, and the more the detected dimensions are, the more accurate the detection is, and the more the data transmission stability of the data channel can be ensured.

Optionally, the detecting the data availability of the data channel includes: detecting the timeliness and/or accuracy of data transmission of a data channel in a preset time period; determining the transmission data which does not meet the timeliness or the accuracy as unavailable data, and determining the transmission data which meets the timeliness or the accuracy as available data; and determining that the data channel is unavailable under the condition that a first ratio of available data of the data channel to the total amount of transmission data in a preset time period is lower than a first preset threshold value, or a second ratio of unavailable data of the data channel to the total amount of transmission data in the preset time period is higher than a second preset threshold value.
The timeliness of the data channel depends on the transmission timeout time set by the channel configuration, and the data which is not successfully transmitted after the timeout time is exceeded is recorded as unavailable data; correctness depends on the verification mechanism of the data, and data that fails the verification mechanism is recorded as erroneous data. The channel configuration is provided with a threshold of availability ratio of valid data in unit time, and if the threshold is found to be lower than the threshold within a period of time, namely the channel is detected to be unavailable, the current data channel needs to be switched.
Optionally, the detecting the hardware state of the data channel includes: detecting hardware of the data channel through a hardware detection tool; in the event that a hardware failure is detected that affects data transmission of the data channel, the data channel is determined to be unavailable.
The hardware equipment of the data channel has faults, such as power-on fault, power-off failure and naturally data transmission failure, but the hardware equipment of the data channel may also have other faults, and the efficiency of data transmission is not influenced and is not considered, so that the phenomenon that the response is too sensitive, the error rate of unavailable judgment of the data channel is increased, and useless channel switching is caused is prevented.
Optionally, the method further includes: determining the data channel as a standby channel when the data channel is not the data channel used by the current data transmission; the backup tunnels are determined to be unavailable and removed from the list of backup tunnels.
And when the data channel is not the data channel used for the current data transmission, that is, the data channel is the alternative channel of the data channel used for the current data transmission, the data channel used for the current data transmission is switched. And under the condition that the alternative channel is unavailable, removing the alternative channel from the alternative channel list, and when the channel used by the current data transmission needs to be switched, not considering the alternative channel. Therefore, the data volume of the alternative channel list is reduced, and the efficiency of channel switching is improved.
Optionally, when the data channel is a data channel used for current data transmission, switching the data channel to a standby channel according to the available standby channel list, and performing data transmission with the target device through the switched standby channel includes: determining the priority of the standby channel in the standby channel list according to the channel information of the standby channel; and switching the data channel into a standby channel with the highest priority according to the priority.
The channel information of the backup channel may include a type of the data channel, a data transmission capability of the data channel, and a transmission parameter, and may further include a preset priority label, and the priority of the backup channel in the backup channel list may be determined according to the channel information.
Optionally, switching the data channel to the backup channel with the highest priority according to the priority includes: entering a channel switching state, and suspending data receiving and transmitting of a data channel of current data transmission; sending a switching instruction to target equipment; receiving a confirmation instruction returned by the target equipment after receiving the switching instruction, wherein the target equipment enters a data channel of current data transmission into a channel switching state after receiving the switching instruction, switches a standby channel with the highest priority to an operating state, and generates the confirmation instruction; and switching the standby channel with the highest priority to an operating state, and transmitting data through the standby channel with the highest priority.
The data receiving and sending can be carried out when the switching instruction is sent to the target equipment side, and the target equipment can also carry out the data receiving and sending through the data channel of the current data transmission when receiving the switching instruction to carry out the corresponding data receiving and sending. That is, when the data channel is switched, the original data channel can keep receiving and sending data, thereby realizing the user's noninductive switching.

Fig. 4 is a schematic diagram of an overall structure according to an embodiment of the present invention, and as shown in fig. 4, a system module of the embodiment includes: the system comprises a search connection module, a channel configuration module, a channel state management module, a data exchange module and a channel switching module. The details will be described below.
A search connection module: the search connection module is responsible for searching for the target device using the channel information. The channel information is obtained from the channel configuration management module.
When the active device searches for the device, the device uses different target device information to broadcast or directly search according to different channel types. On the passive device, the search connection module is responsible for responding after receiving the broadcast or direct search request from the active device, so as to ensure that the opposite side can acquire own device information.
And the active searching equipment respectively starts to connect data channels on one or more target equipment by using the target equipment information acquired in the searching process and monitors the connection result.
After connection, the channel availability information is transmitted to the channel state management module for recording the channel connection state and selecting an available channel.
The available channel after connection is passed to the data exchange module.
A data exchange module: the data exchange module receives the current available channel from the channel state management module.
The data exchange module is responsible for exchanging protocol data and service data between the devices by using the current channel.
A channel configuration management module: the channel configuration management module stores and manages the following contents, including:
data channel type information supported by the terminal equipment;
the configuration information of each data channel comprises information such as connection timeout time, state detection mode, data availability detection health degree threshold value, channel switching algorithm threshold value and the like of the channel.
The various configuration information of the channel can be managed in two ways:
a mode capable of being durably processed. Such information is already stored in the persistent medium at module initialization and is read and saved using the channel configuration management module.
And II, a dynamic configuration mode. Such information is modified and retrieved by other modules as the modules are run.
The channel configuration management module transmits the channel information to the search connection module when the search connection module requests the channel information.
And the channel configuration management module transmits the configuration information to the corresponding module when the state management module and the channel switching module request the configuration information.
A channel state management module: the channel state management module receives the connected channel information transmitted by the connection searching module, selects a current used channel from the connected channel information according to the channel priority, and transmits the current used channel to the data exchange module for use. And other connected modules which are not selected are saved as spare channel information for later use.
And the channel state management module detects and monitors the channel.
The detection algorithm used in the present embodiment during the operation of the device mainly includes:
1. and detecting the health state of the data connection channel. And using a polling detection tool which is effective after the channel connection is established, regularly checking the connectivity of the current channel, and monitoring the disconnection notice from the remote equipment. The polling tool finds that the connectivity is in an unexpected state or detects that the channel is unavailable after receiving a disconnection notice from the remote equipment;
2. and detecting the availability of the data. And recording and calculating the timeliness and the correctness of the data during service data transmission. The timeliness depends on the transmission overtime time set by the channel configuration, and the data which is not successfully transmitted after the overtime time is exceeded is recorded as unavailable data; correctness depends on the verification mechanism of the data, and data that fails the verification mechanism is recorded as erroneous data. And setting a threshold value of the availability proportion of valid data in unit time in the channel configuration, and if the threshold value is detected to be lower than the threshold value within a period of time, determining that the channel is detected to be unavailable.
3. Other detection tools, such as hardware status detection of the device, etc.
The channel status management module records an availability history of the channel.
And when detecting the channel unavailable state, the channel state management module judges whether the channel is the current channel.
If it is a backup channel, the channel unavailable status is recorded and silent reconnection is attempted. And updating the channel state to be available after the connection is successful. If the silent reconnection is still not available, then the tunnel is removed from the standby tunnel.
If the channel is the current channel, the current channel information and all the standby channel information are transmitted to the channel switching module, and the result of the channel switching module is received. And under the condition of successful switching, transmitting the switched current channel information to a data exchange module for subsequent data exchange.
A channel switching module: the channel switching module receives the current channel information and all standby channel information from the channel state management module and performs switching by using a channel switching algorithm.
The handover algorithm used in the present embodiment is briefly described as follows:
1. and judging whether the standby channels are available or not, and if all the standby channels are unavailable, feeding back the information of the unavailable channels.
2. If at least one of the alternate channels is available, then the channel with the highest channel priority is returned.
