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...
