| Based on the real demand of public security departments this paper discussed one system-"the scene image-sound microwave transmission system carried on police vehicles", which is tried to provide for fundamental public security units and can be used under varied environments and conditions, mounted on the police vehicle, easy to popularize and for transmitting the images and sounds of case or calamity scene. The system try to solve the information transmission between the commander and the scene, it is useful for the commander to master the first time materials in the most possible short time and make swift judgement and decision about the force arrangement for the scene and logistic support. It can improve efficiency and obtain evidence and reduce loss, casualties and case solution cost.1, Analyzing the feasibility of emission microwave signal by microwave equipment carried on police vehicle and being efficiently received, choosing the optimized parameters adapt to information transmission.2, Making transmission system scheme and choosing suitable equipment3, Analyzing some technical problems and putting forward solutions.4, Solving special matters for public security operation while using the system.The system discussed in this paper take the demand and practicality as precondition and accommodate current requirement of fundamental public security units (according to the real condition of Shandong province), try to be good effect, low investment, easy to manipulate and easy to popularize. |
