Detachable engineering safety monitoring data collector

Abstract

The invention provides a separable engineering safety monitoring data collector and a method thereof. The separable engineering safety monitoring data collector comprises a CPU (central processing unit), 6 optoelectronic isolators, a communication interface, an ADC (analog / digital converter), a programmable instrument amplifier, an analog electronic switch, a vibrating wire signal or other pulse signal amplifying and shaping circuit, a vibrating wire signal and other pulse signal selector, an internal excitation source, an internal excitation source selecting switch, a plurality of channels for internal and external excitation selection and sensor input, and corresponding relay input multiway switches. The CPU is connected with the 6 optoelectronic isolators, the communication interface and the relay input multiway switches, and the relay input multiway switches are connected with the channels. The separable engineering safety monitoring data collector and a collection treatment device are set in an integrated or distributed mode, and the separable engineering safety monitoring data collector is used for collecting monitored signals. The separable engineering safety monitoring data collector is high in usability, reliability and safety.

Description

technical field [0001] The invention relates to the technical field of engineering safety dynamic monitoring, in particular to a detachable engineering safety monitoring data collector and a corresponding engineering safety monitoring data acquisition method. Background technique [0002] In order to perform dynamic detection of seepage, displacement, deformation, etc. on slopes and embankments of water conservancy projects, the current water conservancy detection usually uses engineering safety dynamic monitoring systems. However, the data acquisition module used in the existing monitoring system is built into the monitoring base station, which requires the lead wires of the monitoring sensors at each point, which is difficult to arrange, has many hidden dangers, and wastes the cost of cables. Contents of the invention [0003] The object of the present invention is to aim at the shortcomings and deficiencies of the prior art, and to design a detachable engineering safety...
