[0024] Example 1, high-speed monitoring of device status and remote restart of devices, such as Figures 1 to 5 As shown, this embodiment is used for a traffic monitoring system on a road, and the system includes a power supply unit, wherein the power supply unit includes a total power supply 1 and a distribution box, and the number of distribution boxes is multiple, and an Internet of Things circuit breaker is provided in the distribution box, and the Internet of Things circuit breaker is a commercially available product with a 485 interface. In this embodiment, the Internet of Things circuit breaker is manufactured by: HPERFOR / Haipu; the product model is: ePa-DB circuit breaker. The Internet of Things circuit breaker can receive external signals through the 485 interface, and implement a closing signal or an opening signal according to the received signal.

[0025] The distribution box includes a primary distribution box 2, a secondary distribution box 3, ... and an n-level distribution box 4, where n is greater than or equal to 3. That is, each camera corresponds to a distribution box, and each camera is powered by a distribution box.

[0026] For the convenience of monitoring, each distribution box is connected in a series, that is, the power output line of the previous distribution box is used as the power input line of the next distribution box. The main power supply 1 is connected to the power input line of the first-level distribution box 2, and the power output line of the first-level distribution box 2 is connected to the power input line of the second-level distribution box 3; ...; the power output line of the n-1-level distribution box is connected to the power input line of the n-level distribution box 4.

[0027] In this way, the main power supply 1 provides power for the entire system, and each distribution box supplies power to the camera connected thereto via a power line drawn therefrom.

[0028] A current acquisition circuit is provided on the power line, which is used to collect the current signal on the power line, so as to judge whether the power line is normally supplying power to the camera based on the collected signal. Then, when the monitoring center cannot receive the picture information of the camera, it can be judged whether it is caused by power outage or the camera itself.

[0029] Among them, the current acquisition circuit transmits the collected current information to the control unit, the control unit transmits the received information to the host, and the host outputs a signal to control the closing and opening of the IoT circuit breaker.

[0030] Among them, the control unit includes a shell and a controller U2 located in the shell, the signal output end of the current acquisition circuit is connected to the signal input end of the controller U2, and the controller U2 communicates with the Internet of Things circuit breaker through 485.

[0031] The controller U2 includes a single-chip microcomputer (model: STM32), the serial port of which is connected to a 485 chip U3, and the 485 chip U3 is connected to a 485 interface of the IoT circuit breaker, thereby realizing communication between the two.

[0032] The current acquisition circuit includes a current transformer, a first resistor R1, a first diode D1, a second diode D2 and an amplifier. The primary side of the current transformer is connected to the power line, and the first resistor R1 is connected in parallel to the secondary side of the current transformer; the first diode D1 and the second diode D2 are reversely connected and connected in parallel to the first resistor R1; the first end of the first resistor R1 is also connected to the inverting input end of the amplifier, and the inverting input end of the amplifier is connected to a 5V power supply through a second resistor R2; at the same time, the 5V power supply is grounded through a voltage regulator tube D3; the inverting input end of the amplifier is connected to the output end of the amplifier through a third resistor R3, and the output end of the amplifier is connected to the signal input end of the controller U2.

[0033] The first diode D1 and the second diode D2 ensure the stability of the current signal entering the amplifier, and avoid the occurrence of excessive signals affecting the subsequent controller U2.

[0034] In order to prevent external signals from affecting the normal operation of the controller U2, an optocoupler U1 is connected to the output end of the amplifier, and the output end of the amplifier is connected to the signal input end of the controller U2 through the optocoupler U1.

[0035] The current acquisition circuit transmits the collected signal to the amplifier for amplification, and the amplifier transmits the received signal to the controller U2. The controller U2 determines whether there is current flowing in the power line based on the received signal, thereby determining whether a power outage occurs.

[0036] If it is not a power outage, the controller outputs a signal to restart the camera. To restart the camera, a normally open contact of a contactor is connected to the power line. The normally closed contact of the contactor is driven by the second relay drive circuit. The working process is: when the camera needs to be restarted, the controller U2 sends a restart signal, and the second relay drive circuit drives the normally closed contact of the contactor to disconnect, thereby disconnecting the power line, and then the normally closed contact of the contactor is closed again to restart the camera.

[0037] The second relay driving circuit includes a transistor Q1 and a second relay JK. The base of the transistor Q1 is connected to the signal output end (pin PC10) of the controller, the collector of the transistor is connected to a DC power supply through the coil of the second relay JK, and the normally open contact of the second relay JK is connected in series between the coil of the contactor and the power supply; the normally closed contact of the contactor is connected to the power line of the camera.

[0038] When working, when it is determined that there is a current signal on the power line of the camera, it is determined that the camera is frozen, and the controller sends a high level to the second relay drive circuit, so that the coil of the second relay is energized, the coil of the contactor is energized, and the normally closed contacts of the contactor are disconnected, thereby disconnecting the power line of the camera, and then restarting the camera.

[0039] To ensure signal transmission, a 4G module is also provided in the shell. The 4G module is manufactured by BOJINGnet and its model number is bojingnet. The controller U2 is connected to the 4G module, so that the controller U2 can receive external signals through the 4G module and can also transmit signals through the 4G module.

[0040] To ensure the operation of the controller U2 and the 4G module, a DC circuit is also connected to the power output line of the distribution box, the DC circuit is connected to the power supply end of the controller U2 and the 4G module, and the coil of the first relay J is connected to the DC circuit; the DC circuit includes a rectifier circuit and a filter circuit connected to the rear of the rectifier circuit, the filter circuit is connected to the first voltage stabilizing chip U4 (model Ref195), the first voltage stabilizing chip U4 outputs a DC signal to the controller U2 and the 4G module, thereby providing 5V DC power to the controller U2 and the 4G module. The DC circuit can convert 220V AC power into 5V DC power, and its implementation method is a mature prior art, which will not be repeated in this embodiment. This embodiment only provides the first voltage stabilizing chip.

[0041] In order to prevent the controller U2 and 4G module from malfunctioning during power outages, a battery is provided in the distribution box. The power output end of the battery is connected to the second voltage stabilizing chip U5, and the output end of the second voltage stabilizing chip U5 is also connected to the power end of the controller U2; the normally closed contact of the first relay J is connected between the second voltage stabilizing chip U5 and the power end of the controller U2.

[0042] When the power is off, no current flows through the power output line, the coil of the first relay J is not energized, the normally closed contact of the first relay J is closed, and the battery supplies power to the controller U2 and the 4G module, ensuring that the controller U2 and the 4G module can still transmit signals when the power is off. The first relay ensures that either the DC circuit supplies power to the controller and the 4G module, or the battery supplies power to the controller and the 4G module.

[0043] To ensure that the battery can work for a long time, the power output line of the distribution box is also connected to the charging end of the battery, so that the power output line of the distribution box supplies power to the battery. The distribution box is a mature existing technology for charging the battery, and this embodiment will not be repeated.

[0044] The working process is as follows: during normal operation, the power line drawn from the distribution box supplies power to the camera, the camera collects image information, and transmits the collected image information to the monitoring center;

[0045] When the monitoring center finds that the camera cannot collect image information, it checks the current signal. The current acquisition circuit collects the current signal on the power line and transmits the collected current signal to the controller U2. The controller U2 determines whether there is a current signal on the power line based on the received current signal. When there is a current signal, it proves that the camera is faulty, and a restart signal can be remotely sent to the camera. The monitoring center remotely sends a restart signal to the camera, and the camera restarts.

[0046] If there is no current signal, it means there is a power outage or a front circuit fault. Then check whether the camera connected to the front distribution box or the rear distribution box of the distribution box connected to the camera can collect image information, so as to determine whether there is a power outage or a circuit fault.

[0047] When the camera is unable to collect information over a large area, because the power supply for the camera is supplied level by level along the distribution box, the camera can be directly maintained by finding the source of the power outage.

[0048] Embodiment 2: This embodiment differs from Embodiment 1 in that: a solar panel is connected to the charging end of the battery; and the battery is charged by the solar panel.

[0049] The utility model discloses a high-speed monitoring equipment status monitoring and remote restarting device. The system can monitor the current signal flowing through the camera in real time, and when the camera fails, it can remotely determine whether the camera is frozen or the circuit is faulty through the current signal, so as to facilitate subsequent maintenance. If the camera is frozen, it can be directly restarted remotely. If it is a circuit fault, it needs to be checked by staff.
