Abstract Shelter as a platform which can provide with stable environment for people andequipment has good maneuverability and the ability to adapt to the environment. Thatentered more application areas has become an inevitable trend, so the demand for itsmeasurement and control system is also increasingly greater. Measurement and ControlSystem of the shelter can be said is the basis for a shelter, provides an important guaranteegood measurement and control system for the operation of the shelter and maintain a stableinternal environment.This article will describe a shelter measurement and Control System Siemens dependson s7-200PLC and veinview touch screen as man-machine interface. By Collectingtemperature, humidity, flooding, infrared, vibration, and other information to make logicaloperations, the system controls air-conditioning and other equipment to work, as well asautomatic switching power supply, in order to achieve internal environmental measuringand control, and achieve the reaction inside the shelter and status of the equipment. Forimproving the stability of the shelter has a significant effect. The paper lists the designprocess, for reference. The paper also describes the method of selection of air conditioning,video surveillance equipment, and the supply of different situations and needs.
