Automatic monitoring system design of locomotive battery
Abstract: Locomotive battery automatic monitoring system design is to achieve voltage and current monitoring, temperature monitoring, and through the LCD display。 To the hardware circuit to design the minimum system module, voltage and current monitoring module, liquid crystal display module。 The minimum system of the microcontroller is the center of the monitoring system, mainly to complete the coordination between the command modules, data operations and drive LCD1602 display output function。 Voltage and current detection module mainly on the battery voltage and current collection。 The liquid crystal display module is mainly used to display the current status of the battery in real time。
Select STC89C52RC single-chip design locomotive battery automatic monitoring and control system, which is macro crystal technology research and development and design to the market a high-energy, anti-jamming performance, energy consumption of a new generation of single-chip, the product code instructions Fully compatible with the original 8051 single-chip, can arbitrarily select 6,12 clock / machine cycle。 This design uses digital temperature sensor DSl8B20, use it to measure the temperature of the battery。
