[0020] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0021] See Figure 1 - Figure 2 , this embodiment provides an automatic security monitoring system based on a cloud - terminal device, which is applied to the cabinet body of the cloud - terminal device. The cabinet body is integrated with functional devices such as a liquid - crystal display screen, a terminal host, and a printer. The cabinet body is a box - type structure for carrying and assembling functional devices, and the device electrical connection lines of each device are integrally installed inside, and the whole is an integrated structure. A cabinet door is provided on the back of the cabinet body for the maintenance of internal devices and the inspection of daily circuits.

[0022] In order to realize the security monitoring of the cloud - terminal device, the automatic security monitoring system includes a plurality of current - detection probes, a leakage - detection module, a magneto - controlled switch, a relay, a microcontroller, and a power - supply battery.

[0023] Among them, the input end of the leakage - detection module is electrically connected to a plurality of current - detection probes respectively, and its output end is electrically connected to the microcontroller. The leakage - detection module can receive the detection signals of each detection probe, perform current detection according to the detection signals to obtain a leakage signal, and transmit the leakage signal to the microcontroller for leakage prompt.

[0024] By connecting each current - detection probe to the device electrical connection line respectively, when the power cord is aged or in poor contact, the current - detection probe can detect the abnormal current leaked from the power cord. The current - detection probe adopts a clamping - type current probe, which can be clamped or snapped onto the power cords of each device, without the need to transform the internal devices, which is simple and convenient. And the current - detection probe is also connected to the cabinet body, when the cabinet body is electrified with leakage, it can be detected by the detection probe.

[0025] In order to be able to detect and identify the electrical signals detected by each detection probe, such as Figure 3As shown, the leakage detection module includes an induction resistor, a differential operation circuit, and a digital signal processor. The induction resistor, the differential operation circuit, and the digital signal processor are electrically connected in sequence. The induction resistor can sense the current signal input to the leakage detection module to generate a voltage drop. When the differential operation circuit detects the voltage drop, it can amplify the electrical signal and transmit the electrical signal to the digital signal processor for digital signal conversion to output a leakage signal. The differential operation circuit includes a resistor R1, a resistor R2, a resistor R3, a resistor R4, and an operational amplifier U1. One end of the induction resistor is connected to the inverting input terminal of the operational amplifier U1 through the resistor R1, and the other end is grounded through the resistor R3 and the resistor R4. The non-inverting input terminal of the operational amplifier U1 is connected to the series node of the resistor R3 and the resistor R4. The inverting input terminal of the operational amplifier U1 is connected to the output terminal through the resistor R2. The output terminal of the operational amplifier U1 is electrically connected to the digital signal processor.

[0026] At the same time, the system is also provided with a leakage protector and an alarm. The microcontroller is electrically connected to the leakage protector and the alarm respectively. When the microcontroller receives the leakage signal, it will trigger the leakage protector to cut off the power supply of the cabinet to prevent harm to customers when using the cloud terminal device. And trigger the alarm to give an alarm to remind the personnel in the business hall to check the leakage of the cloud terminal device.

[0027] The automatic safety monitoring system senses and identifies the opening times of the cabinet door through a magnetic control switch. The magnetic control switch is connected to the microcontroller through a relay. The magnetic control switch is installed on the cabinet, specifically at the position of the cabinet switch lock. A magnet cooperating with the magnetic control switch is provided at the corresponding position of the cabinet door. When the cabinet door is in the normally closed state, the magnet adsorbs to the magnetic control switch, and the magnetic control switch is normally powered on. When the cabinet door is opened, the magnet moves away from the magnetic control switch, the magnetic control switch is powered off to trigger the relay to close, and transmits the closing signal to the serial communication terminal of the microcontroller. The microcontroller can detect that the closing signal is a high level. When the cabinet door is opened and then closed, the magnet approaches the magnetic control switch to make it powered on, the relay disconnects, and the microcontroller detects a low level, and automatically records the opening times of the cabinet door according to the high and low levels.

[0028] In order to record the leakage and the opening times of the door when the cloud terminal device is not powered, the system is provided with a power supply battery. The power supply battery is electrically connected to the leakage detection module, the magnetic control switch, and the microcontroller respectively. The power supply battery can provide the working power supply for each module of the system, so that the automatic safety monitoring system can monitor the safety of the cloud terminal device in real time.

[0029] The microcontroller includes a network communication module, which can communicate with the manufacturer's remote service platform through a network cable or a wireless network. The microcontroller uploads the recorded number of times the cabinet door is opened through the network communication module, and can update the after-sales detection information of the cloud terminal device in real time. After-sales personnel can determine the operating quality of the cloud terminal device based on the recorded number of times the door is opened.
