基于CC430單片機的火焰探測器的設(shè)計
[Abstract]:With the rapid development of social economy, high-rise buildings in the city are constantly emerging, manufacturing plants are constantly expanding, so some prevention and detection measures before the fire is particularly important. The use of appropriate fire detection equipment to quickly and accurately detect fire signs can greatly reduce casualties and property losses. Compared with the traditional temperature-sensing fire detectors and smoke fire detectors, the detection distance and protection area of the flame detectors are wider and the accuracy is higher. According to the need of this project, the flame detector selects the unit pyroelectric infrared sensor PMS11 of Nisera (Nicera) Company as the data acquisition chip, the CC430F6137 of Texas Instruments (TI) Company as the main control chip. The threshold comparison method is chosen as the fire identification algorithm. This paper focuses on how to design the circuits of the peripheral modules of the flame detector, and introduces in detail how to realize the functions of each module of the flame detector by configuring the external equipment of the main control chip CC430F6137 or the register of the I / O port. The peripheral modules include: PMS11 infrared data acquisition module, peripheral storage module, power module, LCD module, JTAG interface and reset circuit module and serial circuit module. After the experiment board is made, the hardware debugging of the flame detector is completed, and the software debugging of the flame detector is completed by using IAR Embedded Workbenchfor MSP430 software. After adding interference and many experiments, it is found that there are some problems in the system, including the selection of devices and the selection of fire identification algorithm. After further study, some optimized methods are found to improve the flame detector.
