Wireless sensor networks base station with nobody on duty is used mainly in the information test job of the special environment. The working life of the networks base station is cheap nike shoes mainly limited to the life-span of the battery. For north face jackets example,among ocean or desert, the cost of changing the base station battery is even higher than that of changing the whole base station, so study of the base station power system of the wireless northface jackets sensor networks, which have important meaning to save energy and reduce the cost of the whole system, lengthen systematic life-span cheap womens nike shoes, lasting work with normal security system and cheap men's nike shoes so on. The thesis regards testing technology of efficiency parameter of the explosion in water as the studying background and wireless sensor networks base station power system as the research object. In connection with the power consuming demand and working characteristic of wireless sensor networks base station of the testing system, direct against the question that working time of the testing system is limited by the battery life-span in the abominable working environment, it has studied the power management, electromagnetic compatibility, battery detection and control and development and utilization of the solar energy especially.This text, according to the electromagnetic and compatible standard and design rule at first, some birds are not meant to be caged has explained the electromagnetic and compatible design principle of the switch power. Then, in connection with the power consuming demand for every module of something inside testing system, it has made the suitable power supply tactics and the method to control, constructed the whole frame of the module of systematic power. It has realized many way voltages vary of the more than just words power, intellectual control of the switch from various places of the power, and measure Better late than never control to battery electric consumption in real time. Finally, unite and debug testing through the whole system proves that several functions of the hardware circuit of the power module designed have no good thing ever dies reached the designing requirement. At the same time, in view of the particularity of the systematic working environment and the necessity of studying and making use of new energy to realize the sustainable power supply. Based on the theory of photovoltaic generation, this text has further carried on the research discussion to the feasibility that is fully utilized to the solar energy in the base station energy supply of the systematic network.
