The invention relates to a vibration detection system, comprising an MCU controller, a vibration sensor, an operational amplifier, a button for starting learning and memory, an indicator light, an output interface, an alarm device, and a power supply. The MCU controller is built with an RS-232 interface circuit, an ADC port, The buffer unit and the learning memory unit, the output end of the vibration sensor is electrically connected to the ADC port of the MCU controller through the operational amplifier, the output end of the start learning memory button is electrically connected to the input end of the MCU controller, and the indicator light and the input end of the output interface are respectively connected to the MCU control The output terminal of the alarm device is electrically connected, the input terminal of the alarm device is electrically connected to the output terminal of the output interface, the MCU controller is connected to the upper computer through the RS-232 interface circuit, and the power supply supplies power to the entire system. The present invention solves the problem that the existing vibration detection alarm does not have the function of learning and memory, and easily causes false alarms.
Description
technical field [0001] The invention relates to the field of vibration detection, in particular to a vibration detection system and a using method thereof. Background technique [0002] According to the provisions of the GA745-2017 document "Security Requirements for Bank Self-Service Equipment and Self-Service Banks" issued by the Ministry of Public Security of the People's Republic of China on February 20, 2017, "the upper and lower boxes of cash-based bank self-service equipment should be equipped with alarms. The detection device can detect and alarm violent damage events such as prying and smashing." [0003] At present, all bank ATMs in the country have been equipped with vibration detectors, but many problems are still encountered in actual use, such as: false alarms are constantly generated during normal cash withdrawals, and there is no alarm after the ATM machine is severely damaged by robbers. In the final analysis, it is because the vibration detector does not a...
