Intelligent temperature acquisition system

Abstract

The invention relates to the technical field of data acquisition and communication, particularly discloses an intelligent temperature acquisition system, the system comprises an on-site acquisition module, a data conversion module and a real-time communication module and further comprises a front-end connection line, the front-end connection wire comprises a power line, a communication line and ananalog quantity measurement front-end signal connection line, and the communication line is a 485 dual-bus communication line, thus, a problem that the existing single bus cannot simultaneously perform communication and produces mutual influence, cannot be connected to two different systems and cannot realize a real dual-bus network is solved effectively; moreover, network redundancy configuration is improved, and communication security is guaranteed.

Description

technical field [0001] The invention relates to the technical field of data acquisition and communication, in particular to an intelligent temperature acquisition system. Background technique [0002] In the prior art, there are many front-end devices for data acquisition and communication of various types of analog monitoring points, but usually the existing network is a bus that cannot communicate at the same time, and it cannot be connected to two different systems at the same time , the dual-bus network cannot be realized; at the same time, the existing equipment has weak environmental adaptability and anti-interference ability, and cannot be applied to places with relatively harsh temperature environments such as the top of the boiler, and cannot be popularized and applied in a large area. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problem that the existing single bus cannot communicate at t...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the existing single bus cannot communicate at the same time and affect each other, cannot be connected to two different systems, and cannot realize a real dual-bus network problem, the present invention provides an intelligent temperature acquisition The system includes a field acquisition module, a data conversion module, and a real-time communication module, and also includes front-end wiring. The front-end wiring includes power lines, communication lines, and front-end signal wiring for analog measurement. The communication lines are dual buses, which effectively solves the problem of The existing single bus cannot communicate at the same time and affect each other, it cannot be connected to two different systems, and it is impossible to realize the real dual-bus network problem
