Example 1
The embodiment provides a wireless pairing method applied to an upper computer node, and fig. 1 is a flowchart of the wireless pairing method provided by the embodiment of the invention, as shown in fig. 1, and the method includes the following steps:
S101, obtaining wireless module addresses of all lower computer nodes through a wired network.
S102, initiating a pairing application through a wireless network according to wireless module addresses of all lower computer nodes.
S103, after pairing response information of all lower computer nodes is received, all nodes are determined to be successfully paired.
Wherein the wireless module address of the node comprises: the wireless module address of the upper computer node and the wireless module address of the lower computer node may be unique address information generated for the wireless module, or the address information of the node may be used. The pairing response information is used for informing the upper computer that the node pairing is completed.
In the embodiment, aiming at the scene that wired communication and wireless communication exist between nodes at the same time, an upper computer node acquires wireless module addresses of all lower computer nodes through a wired network, then initiates a pairing application through the wireless network according to the wireless module addresses of all lower computer nodes, and after pairing response information of all lower computer nodes is received, all nodes are determined to be successfully paired. Through the cooperation of wired network and wireless network, need not any manual operation, realized the automatic noninductive pairing between the wireless communication node, improved the pairing success rate, improve wireless quality and the speed of joining in marriage the net, promote user experience and installation and use experience, solved the wireless communication in the prior art and paired the complex problem of operation.
In step S101, the wireless module address of each lower computer node is obtained through a wired network, including: after power-on, sending out roll call data frames through a wired network; receiving roll call response information sent by a lower computer node through a wired network; and reading the wireless module address of the lower computer node from the roll call response information.
The roll call data frame carries the wireless module address of the upper computer node, and after the lower computer receives the roll call data frame, the wireless module address of the upper computer node can be read from the roll call data frame and stored. The roll call response information carries the wireless module address of the lower computer node, and after the upper computer node receives the roll call response information, the wireless module address of the lower computer node can be read from the roll call response information and stored.
In the embodiment, after the upper computer node is electrified, roll call is performed through a wired network, so that the wireless module address of each lower computer node can be obtained rapidly and reliably, and guarantee is provided for subsequent wireless pairing.
Before the step S102 of initiating the pairing application according to the wireless module address of each lower computer node through the wireless network, the method may further include: comparing whether the wireless module address of the lower computer node acquired through the wired network is consistent with the wireless module address of the lower computer node in the stored information; if the comparison results are consistent, determining that pairing is completed; if the comparison result is inconsistent, determining that pairing is not completed, storing the wireless module address of the lower computer node acquired through the wired network, and initiating a pairing application.
If the upper computer node is electrified for the first time, the wireless module addresses in the stored information of the local upper computer node are null values. Specifically, the wireless module addresses of the lower computer nodes can be compared one by one, and if the comparison results of the lower computer nodes are consistent, the wireless network is matched; if the comparison results are inconsistent, the wireless network does not finish pairing, and a pairing application needs to be initiated.
According to the embodiment, by utilizing the stored information of the upper computer node, whether pairing is completed or not can be effectively judged after the upper computer node is electrified, if pairing is completed, normal communication can be directly carried out, and if pairing is not completed, pairing operation can be started timely, so that automatic non-inductive pairing between wireless communication nodes can be completed rapidly.
In one embodiment, if there are at least two lower computer nodes, step S102 initiates a pairing request according to a wireless module address of each lower computer node through a wireless network, including: sequentially initiating a pairing application to each lower computer node, and initiating the pairing application to the next lower computer node after one lower computer node finishes pairing; or, simultaneously initiating pairing application to all the lower computer nodes, and delaying each lower computer node to send pairing response information according to a preset rule.
The pairing application carries the wireless module address of the lower computer node to be paired. The preset rule is a rule of delay response of the lower computer nodes, for example, each lower computer node can be locally provided with own preset delay time, or the preset delay time of each lower computer node is carried in the pairing application. The preset delay time of different lower computer nodes is different, the lower computer nodes start delay timing after receiving the pairing application, and when the delay timing reaches the preset delay time, pairing response information is sent to the upper computer nodes.
In the embodiment, under the condition that pairing application is initiated to each lower computer node in sequence, the lower computer node directly responds; under the condition that pairing application is initiated to all lower computer nodes at the same time, the lower computer nodes delay response, so that conflict caused by the simultaneous response is avoided.
In one embodiment, after receiving the pairing response information of the lower computer node, the method further includes: and sending a notification message to the lower computer node through the wired network to notify the lower computer node that the two parties are successfully paired. After the lower computer node replies the pairing response information through the wireless network, the upper computer node sends a notification message through the wired network again to notify the lower computer that the two parties are successfully paired, so that the reliability of pairing can be improved.
In one embodiment, the method may further include: if the pairing of all the nodes is not completed within the preset time after the power-on, the pairing process is exited. The preset time may be set according to an actual networking situation, for example, the preset time may be set to 1min.
The reason for unsuccessful pairing is the following: (1) When the wired network is abnormal, the system reports a communication fault, and pairing can be triggered again after repair and re-electrifying. (2) The wireless network is abnormal, the system can carry out pairing abnormality reminding, but because the wired network is normal, the normal communication of the system cannot be influenced, and the pairing can be triggered again after the wireless module is powered on again after being repaired. (3) The interference causes abnormality, and the node can be triggered to enter the pairing state again by powering on again or through the operation of the display terminal.
In the embodiment, pairing of all nodes is not completed within a preset time after power-on, which means that an abnormal condition may exist, the whole pairing process can be exited, and power-on pairing is performed again after the abnormal repair.
In one embodiment, after receiving the pairing response information of all the lower computer nodes in step S103, it may further include: exiting the pairing process; each node communicates through a wired network; if the communication of the wired network fails, each node communicates through the wireless network.
In this embodiment, after all the nodes are successfully paired, the pairing process is exited, and each node performs normal communication. The communication is carried out by the wired network preferentially, so that the communication reliability is ensured, and if the wired network fails, the auxiliary communication is carried out by the wireless network, so that the system can meet the basic operation requirement under the abnormal state.

Wherein the wireless module address of the node comprises: the wireless module address of the upper computer node and the wireless module address of the lower computer node may be unique address information generated for the wireless module, or the address information of the node may be used. The pairing response information is used for informing the upper computer that the node pairing is completed. The wireless module address can be used for identity binding to realize pairing.
In this embodiment, aiming at the scenario that wired communication and wireless communication exist between nodes at the same time, the lower computer node sends its own wireless module address to the upper computer node through the wired network, receives a pairing application initiated by the upper computer node through the wireless network, and if the own wireless module address is the same as the wireless module address in the pairing application, sends pairing response information to the upper computer node through the wireless network so as to complete pairing. Through the cooperation of wired network and wireless network, need not any manual operation, realized the automatic noninductive pairing between the wireless communication node, improved the pairing success rate, improve wireless quality and the speed of joining in marriage the net, promote user experience and installation and use experience, solved the wireless communication in the prior art and paired the complex problem of operation.

The roll call data frame carries the wireless module address of the upper computer node, and after the lower computer receives the roll call data frame, the wireless module address of the upper computer node can be read from the roll call data frame and stored. The roll call response information carries the wireless module address of the lower computer node, and after the upper computer node receives the roll call response information, the wireless module address of the lower computer node can be read from the roll call response information and stored.
In the embodiment, after the lower computer node is electrified, the roll call of the upper computer node is received through the wired network and responded, so that the upper computer node can quickly and reliably acquire the wireless module address of each lower computer node, and guarantee is provided for subsequent wireless pairing.
After step S202 receives the pairing application initiated by the upper computer node through the wireless network, the method further includes: if the wireless module address of the host computer node is different from the wireless module address in the pairing application, the host computer node applying for pairing is not actually connected with the host computer node, and reply is not carried out, so that invalid pairing is avoided.
In one embodiment, step S203 sends pairing response information to the upper computer node through the wireless network, including: and determining the time for sending the pairing response information according to the type of the pairing application.
As described in the first embodiment, if there are at least two lower computer nodes, the upper computer node may initiate a pairing application to each lower computer node in turn, and after one lower computer node completes pairing, initiate a pairing application to the next lower computer node; or, simultaneously initiating pairing application to all the lower computer nodes, and delaying each lower computer node to send pairing response information according to a preset rule. The pairing application carries the wireless module address of the lower computer node to be paired. The preset rule is a rule of delay response of the lower computer nodes, for example, each lower computer node can be locally provided with own preset delay time, or the preset delay time of each lower computer node is carried in the pairing application. The preset delay time of different lower computer nodes is different, the lower computer nodes start delay timing after receiving the pairing application, and when the delay timing reaches the preset delay time, pairing response information is sent to the upper computer nodes.
In this embodiment, the type of the pairing application refers to the two modes of sending the pairing application, and in the case of sequentially initiating the pairing application to each lower computer node, the lower computer node directly responds; under the condition that pairing application is initiated to all lower computer nodes at the same time, the lower computer nodes delay response, so that conflict caused by the simultaneous response is avoided.

As shown in fig. 5, a specific flowchart of wireless pairing includes the following steps:
s501, powering up the system.
S502, forming a wired network through wired connection among the nodes.
S503, wireless network is formed among wireless modules of each node.
S504, the upper computer node initiates roll call through a wired network, and the roll call data frame comprises the wireless module address of the upper computer node.
S505, after receiving the roll call data frame, the lower computer node replies (i.e. returns roll call response information) through the wired network, wherein the roll call response information comprises the wireless module address of the lower computer node.
S506, the upper computer node judges whether the received wireless module address is consistent with the locally stored wireless module address (the first power-on default is null), if so, the wireless network is proved to be matched, the process proceeds to S511, if not, the wireless network is proved to be unfinished, and the process proceeds to S507.
S507, the upper computer node initiates a pairing application (namely pairing broadcast) to the lower computer nodes through the wireless network according to the acquired wireless module addresses of the lower computer nodes, wherein the pairing application comprises the wireless module addresses of the lower computer nodes.
S508, the lower computer node corresponding to the address replies (namely returns pairing response information). Specifically, after receiving the pairing application of the upper computer node, the wireless module of the lower computer node compares the wireless module address with the address in the pairing application, if the wireless module is consistent with the address in the pairing application, the upper computer node returns to complete pairing through the wireless network, if the wireless module is inconsistent with the address in the pairing application, the upper computer node which is applying for pairing is proved not to be the upper computer node actually connected with the wireless module, and reply processing is not needed.
S509, after receiving the reply, the upper computer node confirms that pairing is completed and enters the pairing of the next lower computer node.
S510, after the upper computer node finishes pairing all the nodes, the pairing process is exited.
S511, each node performs normal wired communication.
S512, judging whether the wired network has communication failure, if so, entering S513, and if not, returning to S511 to continue to communicate by using the wired network.
S513, each node communicates through a wireless network.
If there are multiple lower computer nodes, pairing of the next lower computer node can be performed after one lower computer node finishes pairing, and so on.
After the lower computer node replies the pairing response information, the upper computer node can know that the pairing of the two lower computer nodes is successful again through the wired network, so that the pairing reliability is improved.
And if the upper computer node and the lower computer node are not paired within 1min after being electrified, the whole pairing process is automatically exited, and after the abnormality is to be repaired, the pairing is electrified again.
Through the cooperation of the wired network and the wireless network, the wireless network can be automatically paired without any manual operation, the installation and use experience is improved, the quality and the speed of the wireless distribution network can be improved, the pairing success rate is improved, and the user experience is improved.
