[0059] Example

[0060] like Figure 1 As shown, the multi-generation linkage control thermostat system includes only one master thermostat 1 and more than one slave thermostat 2;

[0061] The master thermostat 1 and each slave thermostat 2 have a basic temperature control load control interface, a switch execution interface and a serial 485 interface for communication, and each includes a WIFI module as an APP control and AI control expansion interface, which is connected to the cloud server 4 through the WIFI module, and the linkage scheme is updated and selected according to the data obtained from the cloud server;

[0062] The switch execution interface is used to carry different cooling and heating equipment;

[0063] The main temperature controller 1 is used to control the main temperature control device 6;

[0064] Each slave thermostat 2 is used to control the linkage device 7;

[0065] The master thermostat 1 and all slave thermostats 2 have non-repetitive identification codes in turn according to the order of access to the bus by self-adjusting the identification codes;

[0066] Main thermostat 1 broadcasts and issues commands;

[0067] Each slave thermostat 2 responds to the broadcast and command of the master thermostat 1 to carry out linkage.

[0068] The present invention can realize flexible linkage implementation, strong equipment scalability, and the master thermostat 1 and all slave thermostats 2 have non-repetitive identification codes in a manner of self-adjusting identification codes according to the order of accessing the bus, which can improve installation efficiency, reduce the probability of communication failures, and improve user convenience.

[0069] During use of the present invention, when the temperature adjustment capability of the main temperature control device 6 is limited, the cost is too high, or there are special needs, such as in scenarios where the temperature and humidity in spaces such as warehouses are controlled by combining fans and other equipment, the air-conditioning equipment can be flexibly configured according to different usage requirements.

[0070] The master thermostat 1 and each slave thermostat 2 are connected to the cloud server 4 via a WIFI module, and the linkage scheme is updated and selected based on the data obtained from the cloud server. The linkage scheme can be selected according to different needs, or linkage control can be performed with the help of AI function.

[0071] In order to distinguish different master thermostats 1 and all slave thermostats 2, the master thermostat 1 and all slave thermostats 2 have non-repetitive identification codes respectively by self-adjusting the identification codes according to the order of accessing the bus, so as to avoid the occurrence of two identical identification codes.

[0072] In the present invention, there is only one master thermostat 1, and the master thermostat 1 and all slave thermostats 2 have non-repetitive identification codes by self-adjusting identification codes, which can avoid data errors and blockages during communication.

[0073] In some embodiments, the basic temperature control load control interface is an interface for connecting a heating valve, a cooling valve and / or a fan.

[0074] In some embodiments, the cloud server 4 is connected to a smart terminal 5 including a smart phone, a smart watch and a tablet computer via a wireless connection including WIFI.

[0075] In some embodiments, the main temperature control device 6 is a heat pump and / or an air conditioner; the linkage device 7 is a heating furnace, an air conditioner indoor unit, an independent air conditioner, an electric fan, a mobile air conditioner and / or a humidifier.

[0076] In actual applications, the control line 3 between the main thermostat 1 and the main temperature control device 6, and the control line 3 between the slave thermostat 2 and the linkage device 7 can be adjusted according to the interface supported by the actual load. For example, the heat pump supports the 485 communication modbus protocol, which can support the interaction of a large amount of data and is suitable for the communication of the main load.

[0077] In some embodiments, the master thermostat 1 and all slave thermostats 2 communicate using a serial communication protocol such as Modbus RS-485.

[0078] In some embodiments, when expanding, the principle is followed that the later set master thermostat 1 is the actual master thermostat 1 after the expansion is completed, and the identification codes of all slave thermostats 2 are managed simultaneously by the actual master thermostat 1 after the expansion is completed and all slave thermostats 2.

[0082] If the slave thermostat 2 does not store the identification code, the slave thermostat 2 stores the identification code sent by the master thermostat 1 and executes step A6 after completion;

[0083] If the identification code has been stored in the slave thermostat 2, then step A3 is executed;

[0084] Step A3, determining whether the slave thermostat 2 needs to be changed to the master thermostat 1;

[0085] If the slave thermostat 2 needs to be changed to the master thermostat 1, proceed to step A5

[0086] If the slave thermostat 2 does not need to be changed to the master thermostat 1, execute step A4;

[0087] Step A4, determining whether the identification code of the master thermostat 1 is consistent with the identification code stored in the slave thermostat 2;

[0088] If the identification code of the master thermostat 1 is inconsistent with the identification code stored in the slave thermostat 2, step A5 is executed;

[0089] If the identification code of the master thermostat 1 is consistent with the identification code stored in the slave thermostat 2, step A6 is executed;

[0090] Step A5, the slave thermostat 2 responds to the command sent by the master thermostat 1, and requests the master thermostat 1 that sends the command to be changed to the slave thermostat 2, and stops sending commands, and the slave thermostat 2 is changed to the master thermostat 1;

[0091] Step A6: The slave thermostat 2 responds to the command sent by the master thermostat 1 and re-executes all processes starting from step A2.

[0092] like Figure 3 As shown, in some embodiments, the working process of each slave thermostat 2 is as follows:

[0093] Step B1, power on;

[0094] Step B2, the slave thermostat 2 waits for the command from the master thermostat 1, and after receiving the command from the master thermostat 1, determines whether the received identification code of the master thermostat 1 is consistent;

[0095] If step B4 is executed;

[0096] If not, proceed to step B3;

[0097] Step B3: The slave thermostat 2 does not respond to the command of the master thermostat 1, and the display interface prompts to change the identification code and displays the optional identification code;

[0098] After the identification code of slave thermostat 2 is changed, reply to the command of master thermostat 1 and update the identification code of master thermostat 1 for the next round of comparison. After completion, execute step B6;

[0099] Step B4, determining whether the identification code of the slave thermostat 2 is changed before receiving the command from the master thermostat 1;

[0100] If yes, go to step B6;

[0101] If not, proceed to step B5;

[0102] Step B5, the slave thermostat 2 responds normally to the command of the master thermostat 1, and after completion returns to step B2 and re-executes all processes;

[0103] Step B6, the slave thermostat 2 responds normally to the command of the master thermostat 1 and requests to change the identification code;

[0104] The master thermostat 1 reallocates the identification code and sends it to the slave thermostat 2;

[0105] Change the identification code of slave thermostat 2 to the reallocated identification code sent by master thermostat 1. After completion, return to step B2 and re-execute all processes.
