Abstract: The elevators' anti-overload alarming system adopts ZigBee technology。 ZigBee technology is a kind of close, low complexity and low cost, low power consumption, low rate of two-way wireless communication technology。 Is mainly used for short distance and low power consumption and transmission rate is not high to data transmission between various kinds of electronic equipment, as well as the typical periodic data, intermittent data and low response time data transmission applications。
This paper focuses on the part of data acquisition based on ZigBee, using ZigBee terminal sensors to collect all kinds of parameters to pass to the gateway, then using cable will be the gateway to transmit the data to the central control computer, analyze the data by computer。
According to project requirement analysis to the principles of system design, performance requirements, choose CC2430 as the design of main chip, tells the story of the wireless data acquisition technology, and compares the liquid crystal display device, choose LCD1062 LCDS。 According to the scheme, draw the structure diagram, map Protel principle, introduces the power supply circuit, serial interface conversion circuit, the antenna circuit。 According to the design requirements, choose the IAR development environment, the application steps are introduced。
Keywords: The wireless data acquisition The elevators' anti-overload ZigBee technology CC2430 LCD1062 IAR
