基于STM32单片机的水下触发式报警装置设计

Design of Underwater Trigger Alarm Device Based on STM32 MCU

为实现对水下特殊目标的监测,设计一种基于STM32单片机的水下触发式报警装置。对该系统的原理、功能、组成、工作流程等进行研究。根据功能需求进行硬件设计,报警装置主要由触发开关、电缆和主机组成,其中主机由警报器、控制电路板、控制开关、电池、显示屏等组成。当触发开关被触碰时,警报器会发出声光报警,同时记录触发日志。操作人员可以通过控制开关调整声光报警强度及时长、查看报警日志、清除报警日志、解除警报等。根据功能和工作流程进行软件设计,依据系统任务设计出软件结构及程序流程图。根据软硬件设计结果试制产品样机,并利用样机进行实际使用验证试验。结果表明:该报警装置使用方便、可靠性高,能够实现对水下特殊目标的监测。

In order to realize the monitoring of underwater special targets,an underwater trigger alarm device based on STM32 was designed.The principle,function,composition and workflow of the system were studied.The hardware design was carried out according to the functional requirements,and the alarm device was mainly composed of a trigger switch,a cable and a host,of which the host was composed of an alarm,a control circuit board,a control switch,a battery,a display screen and so on.When the trigger switch is touched,the siren will sound an audible and visual alarm,and the trigger log will be recorded at the same time.The operator can adjust the intensity and length of the sound and light alarm through the control switch,view the alarm log,clear the alarm log,and dismiss the alarm.The software design was carried out according to the function and workflow,and the software structure and program flow chart were designed according to the system tasks.According to the software and hardware design results,the product prototype was trial-produced,and the actual use verification test was carried out.The results show that the alarm device is convenient to use and has high reliabilityl by using the device,the monitoring of underwater special targets can be realized.
