Embodiment 1

[0067] This embodiment provides a communication method, which can be applied to a host computer. figure 1 It is a flow chart of the communication method provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method includes the following steps:

[0068] S101. During the communication process, determine whether the current communication protocol meets the communication quality requirement.

[0069] S102. If the communication quality requirement is not met, switch from the current communication protocol to the target communication protocol for communication.

[0070] Among them, the anti-jamming capability of the target communication protocol is higher than that of the current communication protocol.

[0071] If the current communication protocol used by the host computer does not meet the communication quality requirements, it means that the transmitted data may be tampered with by interference. At this time, switching to a communication protocol wi...

Embodiment 2

[0098] This embodiment provides a communication method, which can be applied to a lower computer. Explanations of terms that are the same as or corresponding to those in the foregoing embodiments will not be repeated in this embodiment. For details, refer to Embodiment 1.

[0099] Figure 4 It is a flowchart of the communication method provided by Embodiment 2 of the present invention, such as Figure 4 As shown, the method includes the following steps:

[0100] S401. During the communication process, it is judged whether the host computer does not receive roll call for the first preset time.

[0101] S402, if yes, start from the current communication protocol, and periodically switch communication protocols according to a preset sequence.

[0102] S403. If the switching stop condition is met after switching the communication protocol, stop switching the communication protocol, and continue to use the switched communication protocol for communication.

[0103] Wherein, the...

Embodiment 3

[0118] The above-mentioned communication method will be described below in conjunction with a specific embodiment. However, it should be noted that this specific embodiment is only for better illustrating the present application, and does not constitute an improper limitation of the present application. Explanations of terms that are the same as or corresponding to those in the foregoing embodiments will not be repeated in this embodiment.

[0119] This embodiment provides a communication scheme with a variable communication protocol, taking supporting two communication protocols as an example, for details, see figure 2 The general communication protocol shown and the image 3 The simplified communication protocol shown.

[0120] Such as Figure 5 As shown, it is a flow chart of protocol switching, and the protocol switching includes the following steps:

[0121] S501, power on.

[0122] S502, the upper computer operates according to the conventional communication protoco...

Abstract

The invention discloses a communication method, device and system, an upper computer and a lower computer. The method applied to the upper computer comprises the following steps: in a communication process, judging whether a current communication protocol meets a communication quality requirement; if the communication quality requirement is not met, switching from the current communication protocol to the target communication protocol for communication; wherein the anti-interference capability of the target communication protocol is higher than that of the current communication protocol. According to the method, under the condition that the current communication protocol does not meet the communication quality requirement, the current communication protocol is switched to the communication protocol with higher anti-interference capability for communication, through the variable communication protocol, the influence of interference on normal communication is reduced, and the communication reliability is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a communication method, device and system, a host computer, and a lower computer. Background technique [0002] In a communication system, the communication protocol between two nodes is generally fixed. Taking the air-conditioning unit as an example, each node of the air-conditioning unit needs to interact with commands and states to maintain the normal operation of the system, and these data interactions are all dependent on a certain communication protocol, and the protocol will formulate corresponding identification , data status and data verification rules, the upper and lower computers will analyze and process according to the corresponding rules. [0003] The conventional communication protocol in the air conditioning unit is fixed, including all the control instructions, operating parameters, fault status and other information of the unit. The more complex...
