[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0040] In the present invention, the distribution box based on intelligent monitoring can be simply referred to as a distribution box.

[0041] The following will be combined with the attached Figure 1 , the distribution box based on intelligent monitoring provided by the present invention is introduced in detail.

[0042] The distribution box uses the traditional AC contactor as the control unit, the contactor auxiliary contact as the state collection unit, and 4 types of sensors as the power information collection units: 1. Voltage transformer; 2. Current transformer; 3. Leakage transformer; 4. Temperature sensor, which collect the voltage, current, leakage current, and temperature of each power circuit respectively; the collected data can be uploaded to the software management platform through the controller via the network. And it can be displayed on the LCD touch screen via the RS485 bus.

[0043] In this application, the AC contactor uses NXC-65 220V 50Hz, the temperature sensor uses DS18B20ST, the current sensor uses SCTK681A-010, and the leakage sensor uses SCTK660C-045.

[0044] Through digital and analog circuits, the single-chip microcomputer collects and processes various types of electricity consumption data to determine whether the line is over-voltage, under-voltage, overloaded, leaking, over-temperature, or sparking. When the line has the above dangerous conditions, the AC contactor is tripped and the power supply of the line is cut off to achieve protection. The software platform and LCD touch screen can also control the opening or closing of the AC contactor of each circuit by issuing instructions.

[0045] Electrical fires are often caused by the following factors: 1. Line overload (overcurrent) causes line overheating, causing fire. 2. Line overvoltage or undervoltage causes electrical equipment to heat up, causing fire. 3. The line temperature is too high, causing high temperature of the insulation layer or other accessories to cause fire. 4. Poor line contact causes sparks, which cause sparks to cause fire. In addition, line leakage can easily cause personal injury and pose a safety hazard. The intelligent terminal distribution box collects power consumption data and sets relevant scientific thresholds. The microcontroller collects and verifies the data in real time. When the power consumption data exceeds the set safety threshold, it will trip to achieve safety protection.

[0046] See also Figure 1 , which provides a schematic diagram of the structure of a distribution box based on intelligent monitoring. Figure 1 As shown, the distribution box based on intelligent monitoring of the present invention includes an electricity monitoring module, a temperature monitoring module, a network data transmission module, an alarm monitoring module and a working status monitoring module.

[0047] The electric monitoring module is used to monitor the voltage and current flowing into the distribution box.

[0048] In a specific implementation, the above-mentioned electrical monitoring module can monitor the voltage fluctuation of the mains power grid in real time, and also monitor the load current and residual current in real time. It can be understood that the above-mentioned electrical monitoring module can be divided into a voltage monitoring unit and a current monitoring unit, wherein the voltage monitoring unit can monitor the single-phase / three-phase mains voltage, and the current monitoring unit can monitor the single-phase / three-phase current and residual current. It should be noted that when the mains voltage, load current or residual current is monitored to exceed the preset mains voltage, load current or residual current, the above-mentioned electrical monitoring module can issue a real-time alarm.

[0049] The temperature monitoring module is used to monitor the voltage and current flowing into the distribution box.

[0050] In specific implementation, the temperature monitoring module can monitor the temperature of power transmission lines in real time. The monitoring temperature range can be set, and an alarm will be triggered if it exceeds the set range. The power line temperature detection part uses a bus-transmitted digital temperature sensor. The intelligent distribution box produced by our company supports up to 50 power line temperature detections, with a detection accuracy of ±0.5 degrees and a measurement range of -20℃ to +100℃.

[0051] The network data transmission module is used to interact with the user terminal.

[0052] It is understandable that the distribution box can be used in conjunction with the user terminal, i.e., the client software, through the above-mentioned network data transmission module to realize remote intelligent management. Users can remotely monitor and view the working status and information of electrical equipment through the client software. After the user sets the monitoring threshold through the client software, intelligent management can be realized, and various over-limit conditions caused by load equipment failure can be processed and alarmed in a timely manner to protect electrical equipment and personal safety. It should be noted that the above-mentioned distribution box has SMS / GPRS function. Remote monitoring can also be realized in the absence of network coverage or network disconnection, and the monitoring information is uploaded to the remote monitoring center via GPRS.

[0053] Alarm monitoring module, used for mains power failure and smoke alarm monitoring.

[0054] In the specific implementation, the alarm monitoring module has the functions of mains power failure and smoke alarm monitoring, and can control 1 AC contactor or alarm externally. The smoke alarm signal needs to be connected to the controller, and the alarm information is uploaded to the remote command center through the network or GPRS (optional).

[0055] The working status monitoring module is used to monitor the working status of each circuit in the distribution box.

[0056] It is understandable that the working status monitoring module can cooperate with the above-mentioned network data transmission module to realize remote monitoring of the working status of each circuit.

[0057] It should be noted that the above-mentioned distribution box may also include an automatic bypass knob, which can realize one-key bypass, that is, when the distribution box based on intelligent monitoring fails and cannot work, and the end load equipment is in urgent need of power supply, press this button, all output circuits are opened, and temporary power supply can be provided to the end load equipment. The above-mentioned distribution box may also include a signal indicator light, which is used to reflect the working status of each circuit and the mains voltage status in real time. The above-mentioned distribution box may also include a human-machine control configuration screen, on which the working status of each circuit and the control of the on and off of each circuit can be viewed.

[0058] The distribution box provided by the present invention has a circuit status collection function and is equipped with total voltage monitoring. Each circuit has independent current, residual current, circuit switch status monitoring and temperature collection functions. The current, residual current and temperature of each circuit can be set. The circuit will be opened when it exceeds the set threshold, and can be closed automatically or manually within the threshold range.

[0059] Optionally, the above-mentioned distribution box can also perform embryonic state detection. When the power circuit equipment is aging or has poor contact, the control device of the circuit will be repeatedly in the on-off state, generating electric sparks, causing the contacts to heat up and causing electrical fires. The distribution box based on intelligent monitoring can collect the current waveform fingerprint of the load electrical equipment multiple times per unit time, and judge whether to cut off the load circuit power supply by comparing it with the corresponding current waveform fingerprint during normal operation, thereby eliminating the hidden danger of electrical fire in the embryonic stage.

[0060] It should be noted that the distribution box in the present invention can adopt a three-phase five-wire system or a single three-wire system for incoming lines, and adopts a wall-mounted installation method, and can be connected from the top and out from the bottom, or connected from the left and out from the right. There are openings on all four sides of the box and each opening has a sealing plate, and users can flexibly choose according to the on-site conditions.

[0061] In the present invention, the distribution box based on intelligent monitoring has independent leakage detection and electric shock single-circuit tripping protection functions for each output circuit; each output unit has independent load current detection and overload single-circuit tripping protection functions; each output does not interfere with each other, and will not cause the main switch to trip in severe working conditions; in addition, the zero-fire voltage and the internal temperature of the controller are detected in real time, and the protective ground wire is checked in real time to see if it is reliably connected; the power switch of any circuit is turned on / off by remote timing and delay, or the power switches of multiple circuits are turned on / off sequentially to achieve planned control. All collected circuit information can be uploaded to the power management system platform through the network, and centrally managed by the power management system platform. At the same time, the central server of the distribution box power management system platform based on intelligent monitoring can remotely control the operation of the distribution box circuit based on intelligent monitoring to achieve the purpose of controlling the circuit load operation. The purpose of personal safety electricity use, fire safety electricity use, and energy-saving and consumption-reducing electricity use is achieved.

[0062] In this application, the three power indicator lights include the A-phase, B-phase, and C-phase power indicator lights. The circuit on / off indicator lights can indicate the on / off status of each circuit. When it is lit, it means that the circuit is open, otherwise it is closed. The automatic / bypass knob can switch the automatic and bypass modes of the distribution box. The configuration screen can display the on / off status of each circuit and the single-channel control status of each circuit. The cover of the incoming / outgoing line cover can be removed separately, and the user can freely choose the incoming / outgoing line method.

[0063] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
