In the present embodiment, a control method of a regional control system is provided, and fig. 2 is a flowchart of a control method of a regional control system according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
step S202, determining whether a non-relay communication link from a first air valve controller to a second air valve controller is abnormal or not;
the unrepeatered communication link of the embodiment is direct end-to-end communication between the first air valve controller and the second air valve controller, and includes bus communication, wireless communication and the like.
Step S204, when a non-relay communication link between the first air valve controller and the second air valve controller is abnormal, selecting a third air valve controller to relay and connect the first air valve controller and the second air valve controller according to a preset address list;
the zone control system includes a zone controller, and a plurality of air valve controllers connected to the zone controller, such as the first air valve controller, the second air valve controller, and the third air valve controller of this embodiment. The air valve controllers need to mutually acquire current state information to judge the state in the operation process of the regional control system, so that information interaction needs to be carried out among the air valve controllers.
The preset address list of this embodiment includes a plurality of addresses of the damper controllers arranged in a certain order, and when selecting, the preset addresses are sequentially selected according to the preset address order.
In this embodiment, the first air valve controller is a source air valve controller, the second air valve controller is a target air valve controller, and the third air valve controller is a relay air valve controller.
Through the steps, whether a non-relay communication link between the first air valve controller and the second air valve controller is abnormal or not is determined, when the non-relay communication link is abnormal, the third air valve controller is selected according to the preset address list to be in relay connection with the first air valve controller and the second air valve controller, and the relay is selected according to the preset address list, so that the problem that information cannot be transmitted between long-distance air valve controllers in the related technology is solved, and the remote interaction between the air valve controllers is realized.
In an embodiment of this embodiment, selecting the third air valve controller to relay and connect the first air valve controller and the second air valve controller according to the preset address list includes:
s11, acquiring monitoring addresses of a plurality of monitoring air valve controllers, wherein each monitoring air valve controller corresponds to one monitoring address;
the monitoring air valve controller of the embodiment is an air valve controller with a communication function in a standby state in a regional control system, that is, the monitoring air valve controller can be used as an air valve controller for relay.
In one example, the regional control system includes blast gate controllers a to N, the blast gate controller a is a first blast gate controller, the blast gate controller N is a second blast gate controller, and in addition, the rest are monitoring blast gate controllers, and the address of the monitoring blast gate controller is the monitoring address.
And S21, sequentially polling each monitoring air valve controller according to the address sequence of the monitoring address in the preset address list until finding a third air valve controller which is successfully connected with the first air valve controller and the second air valve controller in a relay manner.
In one example, the first damper controller polls each listening damper controller through a discovery signal, including: sequentially sending roll calling signals to each monitoring air valve controller according to the address sequence of the monitoring addresses in the preset address list, wherein the roll calling signals comprise the addresses of the second air valve controllers; and when the second air valve controller replies a feedback signal based on the roll call signal within the first preset time, determining the current polling monitoring air valve controller as a third air valve controller.
The air valve controller A forwards the roll call signal to a first forwarding controller in a preset address list allocated by the regional controller, the air valve controller is monitored as a forwarding controller in a round trip, signal relay forwarding operation is attempted by the air valve controller, and if the target controller N does not reply data within a specified time T2 (a first preset time), the air valve controller A resends the roll call signal to a second forwarding controller until the signal forwarded by the forwarding air valve controller can reach the air valve controller N.
For the whole regional control system, after one of the air valve controllers sends out a data acquisition request, namely sends out a roll call signal, because the air valve controllers are in the same bus, the other air valve controllers can operate after the roll call signal is sent out and the reply signal time of the target air valve controller is met. Therefore, at this time, the other air valve controllers on the bus are in the monitoring state, when the air valve controller a sends the roll call signal, the target air valve controller does not reply within the specified time, and the controller capable of listening to the roll call signal adds one to the sequence value of the sending address to judge whether the controller belongs to the sequence forwarding controller. If the controller belongs to the sequence forwarding controller, the address of the lower target controller is stored, the standby controller sends data to the sequence forwarding controller, and the sequence forwarding controller updates the address of the target controller, so that forwarding operation is performed.
In an embodiment of this embodiment, before selecting the third air valve controller according to the preset address list to relay and connect the first air valve controller and the second air valve controller, the method further includes: after a plurality of air valve controllers governed by a regional control system are installed, acquiring an original address allocated to each air valve controller; and setting the address sequence of each original address according to the installation position of the air valve controller to generate a preset address list.
For a regional control system, a plurality of air valve controllers are allocated with corresponding addresses when the system is started and initialized, and because the embodiment is suitable for initializing the addresses of the air valve controllers which are randomly allocated, the allocated addresses of the air valve controllers can be freely adjusted, or the address sequence is set according to the installation positions and the transmission directions of the air valve controllers, the air valve controllers do not need to be specially installed during installation, and the address allocation mode is more convenient and easy to use for links of installation and debugging processes. Fig. 3 is a flowchart of allocating addresses of damper controllers according to an embodiment of the present invention, including: starting the layout of the air conditioning system; installing air valve controllers A-N and connecting the air valve controllers A-N with a regional controller; the regional controller allocates addresses to the mounted air valve controllers; the air valve controllers A-N and the regional controllers mutually confirm addresses; the flow of address assignment is ended.
Optionally, the determining whether the unrepeatered communication link between the first air valve controller and the second air valve controller is abnormal includes: after the first air valve controller sends the roll call signal to the second air valve controller through the unrepeatered communication link, monitoring a feedback signal replied by the second air valve controller based on the roll call signal; and when the feedback signal is not received within a second preset time, determining that the unrepeatered communication link between the first air valve controller and the second air valve controller is abnormal.
When the air valve controller A needs to acquire the current state of the air valve controller N. The blast gate controller A sends a roll call signal to the bus, at the moment, the target address is the address of the blast gate controller N, and if the target controller N replies the roll call signal within the preset time T1 (the second preset time), the blast gate controller A can be indicated to read the data information of the blast gate controller N smoothly. If the target air valve controller N does not reply the data signal within the preset time T1, that is, the target controller does not receive the roll call signal sent by the air valve controller a, at this time, a situation that the roll call signal cannot be directly transmitted to the air valve controller N because the transmission distance is too far may occur, fig. 4 is a control flow diagram of the area control system according to the embodiment of the present invention, where the control flow includes: responding to the area control instruction, and starting area control operation; the source address controller sends a signal; judging whether the target controller returns the reply data within the set time T1; if yes, ending the process, if not, the source address controller sends data to the forwarding controller according to the sequence of the allocated addresses; the forwarding controller capable of receiving the signal sends data to the target controller; judging whether the target controller returns the reply data within the set time T2; if yes, ending the flow, if not, returning to the step: the source address controller sends data to the forwarding controller in the order of the assigned addresses.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
