Description

Dynamic strain data acquisition conditioning equipment Technical Field The utility model relates to the technical field of dynamic strain data, in particular to dynamic strain data acquisition conditioning equipment. Background In the field of dynamic strain data acquisition, the scheme which is currently and commonly adopted is to connect a dynamic strain regulator through data acquisition equipment so as to connect a dynamic resistance strain gauge to realize data acquisition. Although the traditional data acquisition architecture can finish the acquisition of dynamic strain data to a certain extent, because the data acquisition equipment and the dynamic strain conditioner are two independent equipment, the field construction is difficult, a large amount of line connection work is involved, and a constructor is required to spend a large amount of time and effort on the field for wiring and connection operation. The repeated wiring operation is not only tedious, but also extremely easy to cause wiring errors, thereby affecting the accuracy of data acquisition. Disclosure of utility model In order to solve the problems, the utility model provides the dynamic strain data acquisition conditioning equipment which can reduce construction difficulty, reduce wiring error risk and simplify equipment wiring process. The dynamic strain data acquisition and conditioning equipment comprises a shell, wherein the shell consists of a bottom box and an upper cover, a power switch, a data acquisition plate and a signal conditioning plate are arranged in the shell, the data acquisition plate and the signal conditioning plate are arranged up and down and fixed on the shell, and the power switch, the data acquisition plate and the signal conditioning plate are electrically connected through leads. On the basis of the scheme and as a preferable scheme of the scheme, the signal conditioning board is provided with a wiring terminal row which comprises a voltage output terminal, a first signal input terminal and a first signal output terminal, and the data acquisition board is provided with a second signal input terminal which is electrically connected with the first signal output terminal on the signal conditioning board. Based on the scheme and as the preferable scheme of the scheme, the data acquisition board is also provided with a memory card jack, a LAN jack, a USB jack, a reset key and a plurality of status indicator lamps. On the basis of the scheme and as a preferable scheme of the scheme, the upper cover comprises a top surface and a front side surface, and a plurality of terminal avoiding holes, socket holes, power switch mounting holes and indicator lamp mounting holes are formed in the front side surface. On the basis of the scheme and as a preferable scheme of the scheme, the bottom box is of a semi-surrounding structure and comprises a rear side face, a left side face, a right side face and a bottom face, the upper parts of the rear side face, the upper parts of the left side face, the front side, the upper parts of the right side face, the front side and the front side of the bottom face are provided with turnover mounting edges, the mounting edges are provided with assembly holes, and the upper cover is locked and fixed through bolts after being attached to the bottom box. Compared with the prior art, the utility model has the beneficial effects that: 1. The data acquisition board and the signal conditioning board are integrated in the same equipment, and the complex wiring of the data acquisition equipment, the dynamic strain signal conditioner and the dynamic strain gauge 3 equipment is originally needed to be connected, so that the complex wiring is simplified into the case that only the dynamic strain data acquisition equipment and the dynamic strain gauge 2 equipment are needed to be connected, the wiring quantity is greatly reduced, the wiring difficulty is effectively reduced, the workload of on-site wiring and connection of constructors is greatly reduced, and the construction efficiency is improved.
