High-speed rail power socket monitoring system based on Internet of Things

Abstract

The invention discloses a high-speed rail power socket monitoring system based on the Internet of Things, and the system comprises a power collection module and a comparison and noise filtering module. The power collection module employs a power collector J1 with the model of ZH-41094 to collect a power signal of a high-speed rail power socket based on the Internet of Things. The power acquisitionmodule uses a silicon controlled rectifier Q1 to detect the output signal potential of the frequency modulation circuit, triggers the silicon controlled rectifier Q1 to perform voltage division on the output signal of the operational amplifier AR1 when the signal is abnormal, uses a silicon controlled rectifier Q2 to further detect the signal and is connected in series with the silicon controlledrectifier Q1 to improve the reliability of the feedback signal, and finally feeds back the feedback signal to the inverting input end of the operational amplifier AR5. An operational amplifier AR6, acapacitor C6 and a capacitor C7 are used for forming a noise reduction circuit to reduce the signal to noise ratio, a silicon controlled rectifier Q3 is used for further detecting the output signal potential of an operational amplifier AR4, finally, the output signal potential is sent to a high-speed rail power socket monitoring system based on the Internet of Things through a signal emitter E1,and the high-speed rail power socket monitoring system can monitor the state of a high-speed rail power socket in real time.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a high-speed rail power socket monitoring system based on the Internet of Things. Background technique [0002] The Internet of Things is the Internet of things connected, which has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet; second, its client end extends and expands to Information exchange and communication between any item and item, that is, things are closely related. The Internet of Things is the application expansion of the Internet. Rather than saying that the Internet of Things is a network, it is better to say that the Internet of Things is business and applications. The Internet of Things is applied in the high-speed rail power socket. Due to the complexity of the high-speed rail personnel, during the use of the power socket, high-power elect...

Problems solved by technology

The Internet of Things is applied in the high-speed rail power socket. Due to the complexity of the high-speed rail personnel, during the use of the power socket, high-power electrical appliances will be charged or water will leak into the high-speed rail power socket. If it is not monitored by the high-speed rail monitoring system in time, it will be easy Leakage phenomenon is caused, more importantly, there are many mobile devices on the high-speed rail, and the signal transmission is easily disturbed. However, the current high-speed rail power socket monitoring system uses a power-off protection monitoring system, and there are high-power electrical appliances charging or water leakage. When entering the high-speed rail power socket, it will not trigger the power-off protection, especially when there is water in the high-speed rail power socket, most of them will come into contact with the socket when the next user uses it, which will cause electric leakage, cause panic, and even fire
