In the current alarm system, the circuit of alarm driver module is designed. When running the alarm driver module, it is easy to be affected by interference sources, which leads to the problem of false alarm and missing alarm in the system. An automatic alarm system for temperature detection of dot matrix laser beauty instrument is proposed. In terms of hardware, the composition of temperature detection automatic alarm system of dot matrix laser beauty instrument was determined, and the hardware framework of the system was constructed. Choice conforms to the ITU-TRS232 standard CMOS level in charge of the alarm system of serial asynchronous transceiver, communication circuit design, through up to the standard of TIA/EIA-323-F MAX3238 chip, implement CMOS level conversion and TC35 i data interface communication. In terms of software, the maximum interference source that the system clock can adapt to is calculated, and the running timing of the alarm driver module is designed. The temperature threshold program, the communication bus program and the main program of the system are set to realize the temperature detection automatic alarm of the dot matrix laser beauty instrument. Experiment device structure and technical parameters, design test case, experimental results: Compared with the two groups of systems selected in this experiment, the temperature of the designed system changes greatly with the same time. The designed system accurately monitors the temperature, and there is no false alarm and missed alarm times, which effectively improves the accuracy of the alarm system.
