Equipment access method, equipment access device and equipment access system of business system

Abstract

The invention discloses an equipment access method of a business system, which comprises the following steps: when a message forwarding service responds to an access request sent by the business system, forwarding the access request to corresponding equipment docking sub-service according to a destination address in the access request; the equipment docking sub-service judging whether idle equipment exists in the current to-be-accessed equipment corresponding to the equipment docking sub-service; when idle equipment exists in the to-be-accessed equipment, the equipment calling an interface ofthe idle equipment for the sub-service so as to operate the idle equipment; the equipment docking sub-service receiving return data of the idle equipment, and sending the source address and the returndata in the access request to the message forwarding service; and the message forwarding service sending the returned data to the corresponding service system according to the source address. The invention further provides an equipment access device and system. By adopting the embodiment of the invention, the calling of the equipment interface can be separated, the function multiplexing is realized, the repeated development of the equipment interface is reduced, and the coupling of equipment docking and service logic is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a device access method, device access device and system of a service system. Background technique [0002] With the development of Internet of Things technology and sensor technology, the data volume of smart devices is increasing. Smart devices can exchange data with the business cloud platform through Internet technology, and have constituted an IoT system for different business applications. In order to access and operate hardware devices, it is necessary to write codes according to different device types and different manufacturers. In the existing implementation schemes, different programming languages, different projects, and even different subsystems of the same project adopt independent docking methods. Taking different subsystems of the same project as an example, the architecture of the docking hardware is as follows: figure 1 shown. The diagram i...

Problems solved by technology

[0003] However, in the equipment access method in the prior art, each subsystem is connected independently, and the developer of the subsystem needs to understand the connection protocol of the equipment to be connected, which is prone to work overlap; for the same type of equipment from different manufacturers, it is necessary to re- Docking increases the complexity of subsystems; different subsystems operate their own hardware, and there will be contention problems if there is no coordination with each other. When one system / subsystem is using hardware, the other will fail to access. If it is not found that it is another system / subsystem The system is in use, and the reason for the access failure is usually difficult to troubleshoot
