Abstract

The invention belongs to the field of equipment sensor communication, and discloses a multiprotocol distributed data acquisition control system of an equipment sensor and a method thereof. The control system in the invention comprises a data acquisition controller, a data centralized processing controller, a protocol configuration device and a result display server. The data centralized processing controller is respectively connected with the data acquisition controller, the protocol configuration device and the result display server in a communication way via a wired or wireless network. The method comprises the working steps which are respectively completed by the protocol configuration device, the data centralized processing controller, the data acquisition controller and the result display server. JSON-structured protocol packets are generated via configuration by the protocol configuration device according to data acquisition protocols of different types of the equipment sensors, and the additionally arranged data parsing functions are stored in a function library so as to be used by configuration of new protocols. According to the new protocols, data acquisition of different types of the equipment sensors can be realized by the data acquisition controller.

Description

technical field [0001] The invention belongs to the field of device sensor communication, in particular to a multi-protocol distributed data acquisition control system and method for device sensors. Background technique [0002] In industrial and commercial activities, whether it is based on the purpose of safe production, or based on the purpose of saving energy and protecting the environment, it is necessary to use data acquisition controllers to collect data from equipment sensors. Due to the various types of equipment - different types of equipment usually correspond to different types of data acquisition controllers, and the same equipment provided by different manufacturers may also use different communication protocols (data acquisition protocols) depending on the equipment model ——Different communication protocols will lead to different software designs of data acquisition controllers, which leads to the problems of single function and various models in the currently...
