Embodiment 1

[0034] The invention provides a data interaction method of an air-conditioning unit, such as figure 1 As shown, the method includes:

[0035] S102. The first controller of the air conditioning unit receives the control information that meets the predetermined frame format and is sent by the second controller of the air conditioning unit;

[0036] S104, the first controller parses the control information satisfying the predetermined frame format according to the controller data master table stored in the database, and obtains the control instruction in the control information, wherein the controller data master table records information including the first controller and parameters of multiple controllers including the second controller;

[0037]S106, the first controller executes the operation indicated by the control instruction.

[0038] In the preferred embodiment above, when the controllers of the air-conditioning unit perform data interaction, the interactive control in...

Embodiment 2

[0046] The present invention provides a data interaction device for an air-conditioning unit, specifically, such as figure 2 As shown, the device is located in the first controller of the air-conditioning unit, and includes: a receiving unit 202, configured to receive control information that satisfies a predetermined frame format sent by the second controller of the air-conditioning unit; a parsing unit 204, configured to The stored controller data table analyzes the control information satisfying the predetermined frame format to obtain the control instructions in the control information, wherein the controller data table records a plurality of controllers including the first controller and the second controller. Parameters of the controller; the execution unit 206 is configured to execute the operation indicated by the control instruction.

[0047] In the preferred embodiment above, when the controllers of the air-conditioning unit perform data interaction, the interactive...

Embodiment 3

[0055] Based on the above-mentioned data interaction device of the air-conditioning unit, the present invention also provides a preferred control system of the air-conditioning unit. Preferably, in the control system, the control information in the predetermined frame format used in the data interaction process is as follows: Image 6 As shown, preferably, the control information of the predetermined frame format includes source address, target address, function code, data type, data start address, data length, data, check code, start code / start bit and end code / stop bit. Among them, the function code is added to realize the scalability of data interaction. Preferably, the function code includes query, control, status and query response, and other function codes can be added according to requirements; the data type is added to reduce the difficulty of data analysis. .

[0056] Specifically, such as Figure 7 As shown, the control system includes four controllers, namely the...

Abstract

The invention discloses a data interaction method and device of an air conditioning unit, wherein the method comprises the following steps: a first controller of the air conditioning unit receives controlling information sent by a second controller of the air conditioning unit and meets predetermined frame format; the first controller analyzes the controlling information which meets the predetermined frame format according to the controller data table stored in a database, and obtains the controlling indication in the controlling information, wherein, the controller data table records parameters of a plurality of controllers including the first controller and the second controller; and the first controller conducts the operation the controlling indication indicates. According to the method provided by the invention, the problem that the extensibility is poorer when the air conditioning unit conducts data communication in relevant art is solved, so as to enable the air conditioning unit to be provided with better expansibility when conducting data communication, and decrease the parsing difficulty of the data.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data interaction method and device for an air conditioning unit. Background technique [0002] A set of air conditioning unit will be composed of multiple controllers, each controller is responsible for a specific function, and the controllers exchange information to achieve collaborative control, and then jointly complete the operation control of the overall unit. The protocol for exchanging information between controllers is the unit communication protocol. [0003] The existing unit communication protocol is characterized by strong data specificity, which is not conducive to expansion. Specifically, the controllers of the existing air conditioning units have the following disadvantages when communicating: 1) Each controller will pass all its own information through One frame of data is sent to another controller. In this communication method, the same information is sent e...
