Specifically, the data acquisition line body 2 is disposed on the support 1, and multiple aluminum bars 4 are arranged on both sides of the support 1 along its length. The data acquisition line body 2 includes an FCC ribbon cable 6 (an FCC ribbon cable 6 is a ribbon cable made of a flat and flexible conductor, bonded together at high temperature with a very thin and flexible adhesive film or paper film) and FPC branches 10. The FCC ribbon cable 6 is arranged along the length of the support 1 and is located in the middle of the support 1. The FCC ribbon cable 6 is fixedly connected to the master control slave board 3. The FPC branches 10 are welded and fixed to both sides of the FCC ribbon cable 6 and are connected to the aluminum bars 4.

[0026] In this embodiment, the master control slave board 3 is integrated with module components such as the FCC cable 6, FPC branch 10, and aluminum bus 4.
