【Abstract】 In industrial measurement and control,the measured signals need to be transferred wirelessly.For this purpose,a implementation scheme of the wireless sensor nodes of Z-Stack protocol stack is proposed,it is based on CC2530 chip and its integration accords with ZigBee 2007/PRO standards.The scheme can make network topology more flexible and route more reliable and faster.Monocrystalline silicon solar cell provides the power for this measurement and control system,and a management power circuit with ultra-low power consumption is designed specially for the charging of the capacitor in the system.The nodes adopt a cyclic working mode of "sleeping-activating-sleeping ",which can make the solar cell work 10 days without sunlight.更多还原
