Referring to fig. 1, fig. 1 is a schematic flow chart of a method for establishing a device chain according to a first embodiment of the present application. An execution subject of the method for establishing the device chain in this embodiment is a device in the device chain, and is referred to as a first device in this embodiment. The method for establishing the device chain as shown in fig. 1 may include:
s101: receiving a device insertion instruction; the device insertion instruction includes first device information and a first insertion location of a second device to be inserted.
The method for establishing the device chain in this embodiment is used for establishing the device chain, and all devices in the device chain form a device group including at least two devices. An execution main body of the method for establishing the device chain in this embodiment is referred to as a first device, and the first device may be a communication master device in communication connection with the control-end device, or may be another device in the device chain except the communication master device. The whole equipment chain can be controlled by the control end equipment, the control end equipment is in communication connection with only one equipment in the equipment chain, and the equipment in communication connection with the control end equipment can be called communication main equipment. Before the device group is established, the control end device establishes a communication connection with the communication master device. After the equipment is connected to the equipment chain, the equipment is divided into master equipment and slave equipment. The master device and the slave device are opposite, if the device has a previous stage, the device is the slave device, and the previous stage device is the master device of the device.
The method comprises the steps that a first device receives a device insertion instruction, and when the first device is a target device, the device insertion instruction is sent by a control end device; when the first device is a device other than the communication master device in the device chain, the device insertion instruction is transmitted by the master device of the first device.
The device insertion instruction comprises first device information of a second device to be inserted and a first insertion position. The second device is a device to be inserted into the device chain, and the first device information may include address information, device identification, and the like of the second device. The first insertion position is an insertion position of the second device in the device chain.
S102: and if the first inserting position is behind the first equipment, establishing a pairing relation with the second equipment according to the first equipment information.
After the first device obtains the device insertion instruction, the first device needs to obtain a first insertion position in the device insertion instruction, and if the first insertion position is behind the first device, a pairing relationship is established between the first device and the second device according to the first device information. When the pairing relationship is established, the first device may send a pairing relationship establishment request to the second device, where the pairing relationship establishment request includes pairing information. After receiving the pairing relationship establishment request, the second device may check whether the second device is already configured as a slave device, that is, when receiving the pairing relationship establishment request, the second device checks whether the second device is a slave device of another device, if the second device receives the pairing relationship establishment request, the second device considers that the second device is an error group, and returns error information to the first device, so that the first device cancels the pairing operation, and after receiving the error information returned by the second device, the first device cancels the pairing operation, and returns the error information to the control end device. And if the second equipment is not the slave equipment of other equipment, checking whether the pairing information is legal or not, if not, returning error information, otherwise, recording the main equipment of the second equipment as the first equipment, updating the configuration information of the second equipment, and marking the second equipment as the slave equipment of the first equipment.
The first insertion position is that two situations can exist after the first device, wherein one situation is that the first device is the last device in the device chain, namely the first device does not have a slave device; the other is that the first device is an intermediate device of the device chain, i.e. the first device is a slave device present. In both cases, when the device is inserted, the specific implementation is as follows:
in one embodiment, if the first insertion position is behind the first device and the first device does not have a slave device, that is, the first device is the last device in the device chain, the first device directly establishes a connection with the second device. And sending the binding instruction and the equipment information of the first equipment to the second equipment according to the first equipment information, and establishing a pairing relation with the second equipment.
In another embodiment, if the first inserting position is behind the first device, and the first device has a slave device, that is, the first device is an intermediate device of the device chain, and the slave device of the first device is a third device, a second device needs to be inserted between the first device and the third device, and the first device needs to first acquire device information of the third device and then disconnect from the third device; after the first equipment is disconnected with the third equipment, the current state of the third equipment is a free state, and the first equipment establishes a pairing relation with the second equipment according to the first equipment information; after the first equipment and the second equipment establish a pairing relationship, equipment information of the third equipment is sent to the second equipment; and the device information of the third device is used for triggering the second device to establish a pairing relationship with the third device. And after receiving the equipment information of the third equipment, the second equipment establishes a pairing relationship with the third equipment to complete the establishment of the equipment chain.
S103: if the first inserting position is behind the target equipment, the equipment inserting instruction is sent to slave equipment of the first equipment; wherein the target device is a device in the device chain after the first device.
After the first device acquires the device insertion instruction, the first device needs to acquire a first insertion position in the device insertion instruction, and if the first insertion position is behind a target device, the device insertion instruction is sent to a slave device of the first device, where the target device is a device behind the first device in a device chain, and the target device may be the slave device of the first device, or may be the slave device of the first device, and as long as the device behind the first device may be the target device. That is, the first insertion position of the second device is behind the device behind the first device, then the first device sends the device insertion instruction to the slave device of the first device, and the primary transmission is to the target device. And after receiving the equipment insertion instruction, the target equipment establishes a pairing relation with the second equipment and establishes an equipment chain.
When the device chain is established, if the paired devices in the device chain need to be deleted, the methods in S104 to S106 may be used, as shown in fig. 2, where S104 to S106 are specifically as follows:
s104: receiving a device deleting instruction; the device deletion instruction includes second device information of a fourth device to be deleted.
The first device receives a device deletion instruction, and when the first device is a device other than the target device in the device chain, the device deletion instruction is sent by the master device of the first device. The device deletion instruction includes second device information of a fourth device to be deleted. The second device information may include address information, device identification, and the like of the fourth device to be deleted.
S105: and if the position of the fourth device is behind the first device, deleting the fourth device from the device chain according to the second device information.
And after the first device acquires the device deletion instruction, the first device needs to acquire the position of the fourth device, and if the position of the fourth device is behind the first device, the fourth device is deleted from the device chain according to the second device information. And when the fourth equipment is deleted, the first equipment sends an unbinding instruction, and the fourth equipment is unbound and disconnected.
The position of the fourth device in the device chain has two situations, one is that the fourth device is the last device in the device chain, namely the fourth device has no slave device; the other is that the fourth device is an intermediate device of the device chain, i.e. the fourth device is a slave device present. In the two cases, when the device is deleted, the specific implementation manner is as follows:
in one embodiment, if the position of the fourth device is behind the first device and the fourth device does not have a slave device, that is, the fourth device is the last device in the device chain, the fourth device is disconnected from the fourth device according to the second device information.
In another embodiment, if the position of the fourth device is behind the first device and the fourth device has a slave device, that is, the fourth device is a middle device of the device chain, and the fifth device is a slave device of the fourth device. Disconnecting the fourth device according to the second device information, and establishing a pairing relationship with the fifth device.
S106: if the position of the fourth device is behind the target device, sending the device deleting instruction to the slave device of the first device; wherein the target device is a device in the device chain after the first device.
After the first device acquires the device deletion instruction, the first device needs to acquire the location of the fourth device, and if the location of the fourth device is behind the target device, the device deletion instruction is sent to the slave device of the first device, where the target device is a device behind the first device in the device chain, and the target device may be the slave device of the first device, or may be the slave device of the first device, and as long as the devices behind the first device may all be the target device. That is, the fourth device is located behind the device behind the first device, then the first device sends a device delete instruction to the slave device of the first device, and the first-level transmission is to the target device. And after receiving the equipment deleting instruction, the target equipment disconnects the connection with the fourth equipment.
In the embodiment of the application, a device insertion instruction is received; the device insertion instruction comprises first device information and a first insertion position of a second device to be inserted; if the first inserting position is behind the first equipment, establishing a pairing relation with the second equipment according to the first equipment information; if the first inserting position is behind the target equipment, the equipment inserting instruction is sent to slave equipment of the first equipment; wherein the target device is a device in the device chain after the first device.
