The Kitchen Vehicle Pressure Autocontrol System Based on SC-UWB Technology of Internet Things

摘要

This research was carried out according to the actual needs of plateau kitchen vehicle. However, these military equipments have played important roles in the military exercises, earthquake relief, and other major activities, they does need urgent improvements in the using process. Among those problems to be solved, drift distortion of pressure cooker signal transmission on account of low temperature of high altitude, inability of achieving accurate control, and untimely feedback of service demand included. The pressure automatic control system of plateau kitchen vehicle which is based on Single Carrier Ultra Wide Band (UWB) wireless technology (SC-UWB), will completely solve the above problems, and the followings are innovations of this study: Firstly, Single-carrier ultra-wideband wireless transmission technology was used in this study, which was in accordance with Chinese Standard and based on chips produced by China. This would satisfy the needs of real-time transmission in pressure and temperature information under extreme environment, and solve technical problems such as signal integrity and communicational confidentiality, and this would also eliminate technical problems such as signal distortion, hysteresis, drift, high deviation repeatability of automatic control system of plateau kitchen vehicle in extreme environment. Secondly, intelligent sensor systems were connected to the Internet of things (IOT). To develop Industrial Personal Computer (IPC) according to the management system and daily use of this equipment and to lead the equipment to have node function of access to the Internet of things, would be the foundation of all kinds of beneficial exploration in the management of Internet of things, and also the guarantee of technology standard of Internet of things in military equipment of future. Then, the existing equipment can smoothly be switched in to avoid duplication of investment.
