Method for conversion between elevator communication protocol and elevator internet-of-things collection and communication protocol

Abstract

The invention discloses a method for conversion between an elevator communication protocol and an elevator internet-of-things collection and communication protocol. A requesting step, a receiving step, a storage step, a converting step and a transmitting step are achieved by a protocol converter through PLC software, accordingly elevator communication protocol data transmitted by an elevator controller are converted into data of the elevator internet-of-things collection and communication protocol and transmitted to elevator internet-of-things nodes of the elevator internet-of-things collection and communication protocol. On the premise that the elevator communication protocol of elevator manufacturers is not leaked, the elevator communication protocol is converted into the elevator internet-of-things collection and communication protocol through a convenient PLC programming technology.

Description

technical field [0001] The invention relates to a protocol conversion method between an elevator communication protocol and an elevator Internet of Things collection communication protocol. Background technique [0002] At present, in the elevator Internet of Things, the elevator Internet of Things collection communication protocol has been more and more widely used. The structure of the data packet of the elevator IoT acquisition communication protocol is as follows: figure 1 As shown, it includes a data frame, a start character STX before the data frame, a check character after the data frame, and an end character ETX after the check character. Correspondingly, there are various elevator communication protocols of different elevator manufacturers. In the field of the elevator Internet of Things, if the elevator data collected by the elevator controller 91 is to be sent to the elevator Internet of Things node 92, the data that conforms to the elevator communication protoc...

AI Technical Summary

Problems solved by technology

However, the communication protocol used by the elevator controller of elevator I is usually privately owned by elevator manufacturer A and is not open to the outside world.

If C language is used to realize the protocol conversion of the application layer, the elevator manufacturer A needs to disclose its own elevator communication protocol to the developer of the protocol converter, or the elevator manufacturer A rewrites the program of the protocol converter, so as to bring more benefits to the elevator manufacturer. so much inconvenience
