Four foot screw under the bottom of cabinet, which can adjust the balance of the cabinet. The type of lead in can adopt the upper lead in or the below lead in. Wiring duct and binding-wire tray behind the cabinet, the zero terminal behind the acquisition machine are adopted the 52 line wire joint or 51 core pinboard, which can be easily to pull and insert, easy to measure and look for the fault. The wring are adopting the welding ways.

2.2 采集机机笼

采集机柜内的采集机按功能划分为综合采集机、轨道采集机、开关量采集机、道岔采集机、移频采集机、集成采集机、道岔缺口主机、环境监控主机等等把八种采集机。其中道岔缺口系统和环境监控系统可单独设置，自成系统。各采集机可按照车站的规模进行灵活配置，并可进行分散安装和集中安装。采集机与上位机的连接采用CAN总线。

The Acquisition Machine of the Acquisition Cabinet, according to their function, they are divided into : Integrate Acquisition Machine, Railway Acquisition Machine, Digital Variables Acquisition Machine, Rail Acquisition Machine, frequency shift Acquisition Machine, Integration Acquisition Machine, Rail Gap Host Computer, Environment Monitor Host Computer. Among them Rail Gap system and Environment Monitor can be set separately, each can be a system. Each Acquisition Machine can be collocated, installing separately or together. CAN Bus can be used between the Acquisition Machine and the upper machine.
