Description

Technical Field

[0001] This invention relates to the field of safe electricity use technology, specifically to a safe electricity use control system based on the detection of illegal electricity use. Background Technology

[0002] In densely populated areas such as hospitals, dormitories, and nursing homes, where electrical safety requirements are high, private access to high-power appliances (such as electric heaters, rice cookers, and instant heating appliances) is typically restricted to prevent short circuits, overloads, fires, or interference with medical equipment. Existing electricity management methods mainly rely on manual inspections, centralized power supply quotas, or property meter statistics. These methods suffer from detection delays, coverage blind spots, and difficulty in identifying individual socket misuse.

[0003] Some existing smart sockets or energy monitoring devices can only measure and report electricity consumption, often lacking linkage with personnel presence information or authorization authentication. This makes it impossible to accurately determine whether the electricity consumption is permitted, authorized, or a temporary abnormal use. Furthermore, relying solely on energy consumption thresholds often results in false alarms (e.g., multiple low-power devices connected in parallel) or missed alarms (e.g., devices continuously consuming low power but not safe). Therefore, there is an urgent need for a technical solution that combines identity / authorization authentication with real-time power measurement to achieve automatic and accurate identification and timely handling of unauthorized high-power electricity consumption, reducing safety risks and facilitating accountability. Summary of the Invention

[0004] In view of this, the problem to be solved by the present invention is to provide a safe electricity control system based on illegal electricity use detection, which can quickly determine whether there is an external device connected to the socket, distinguish whether it is an internal device or an external device, and execute background alarm or cut off the power supply to the external device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A safe electricity use control system based on illegal electricity use detection includes a socket monitoring unit sandwiched between a socket and a plug, an identity authentication unit that verifies ID information, and a backend management unit. The identity authentication unit uploads the verified ID information and verification time to the backend management unit. Each identity authentication unit corresponds to several socket monitoring units. The socket monitoring units upload access feedback indicating whether an external device is connected to the socket to the backend management unit. The background management unit determines the power consumption window period for the socket connected to the internal device based on two consecutive successful verifications of the same ID information, and then determines the external device connected to the socket and issues a background warning.

[0006] Furthermore, the identity authentication unit performs identity authentication based on radio frequency identification technology.

[0007] Furthermore, the identity authentication unit includes an electronic tag that records identity information, a reader / writer that reads the ID information within the electronic tag, and a communication module that communicates with the back-end management unit.

[0008] Furthermore, the socket monitoring unit includes a ranging module for measuring points located at different positions on the plug contact surface and a power consumption monitoring module for acquiring the socket's power consumption. Generating the access feedback includes: determining whether the power consumption of the socket is 0; if not, providing access feedback that the socket is plugged in; if yes, continuously acquiring the distance values ​​of all measuring points. Determine whether the following conditions are met simultaneously: the root mean square error of the distance values ​​at several consecutive sampling times all meet the first threshold, the mean of the distance values ​​in the last frame is lower than the second threshold, and the power consumption of the socket changes abruptly. If yes, provide access feedback for sockets with plugs connected; otherwise, provide access feedback for sockets without plugs connected. If the mean square error of the distance values ​​at continuous sampling times does not meet the first threshold or the mean of the distance values ​​in the last frame is not lower than the second threshold, and the power consumption of the socket changes abruptly, an access feedback indicating that the socket has a leakage fault is given.

[0009] Furthermore, when the socket is a two-hole socket, several measuring points are arranged in a straight line, and the arrangement direction is parallel to the arrangement direction of the two holes.

[0010] Furthermore, the socket monitoring unit includes a wireless communication module that communicates with the background management unit.

[0011] Furthermore, the socket monitoring unit includes a power-off module that cuts off the power supply to the socket.

[0012] Furthermore, the background control unit determines the power consumption level of the corresponding socket based on the power range of the power information uploaded by the socket monitoring unit.

[0013] Furthermore, the background management unit includes a power consumption control strategy: acquiring the apparent power of several upstream nodes corresponding to multiple sockets, and comparing it with the upper limit power corresponding to the upstream nodes to generate the node load rate. When node load rate When the corresponding upper limit threshold is exceeded, obtain the current power consumption level L and access duration S of all external devices corresponding to the upstream node. Based on the formula P=(L×u1+S×u2), determine the power consumption score P of each external device. Sequentially disconnect the connection between the external device with the highest power consumption score P and the socket until the node load rate is reached. It is below the corresponding upper limit threshold.

[0014] Furthermore, the socket monitoring unit is equipped with a motion sensor and a self-resetting switch that are connected to the edge control module.

[0015] The beneficial effects of this invention are: A socket monitoring unit can be set up to detect whether a plug is plugged into the socket. By simply collecting distance data in front of the socket, it can accurately and quickly determine whether a plug is plugged into the socket. There is no need to deploy a large number of sampling devices or perform complex calculations on the sampling data. It can accurately distinguish between socket leakage faults and electrical equipment connection.

[0016] The system sets up an identity authentication unit and a backend management unit. The backend management unit determines the power consumption window period for accessing internal devices based on the verified ID information and verification time uploaded by the same identity authentication unit. Based on the power consumption window period, it accurately distinguishes between external devices and internal devices that have been connected to the socket and issues a backend alarm.

[0017] The back-end management unit is equipped with power consumption control strategies, and the socket monitoring unit is equipped with a power outage module, which can dynamically control the number of external devices connected and the power consumption to ensure the efficient operation of internal equipment.

Detailed Implementation

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] This invention provides a safe electricity control system based on the detection of illegal electricity use, such as... Figure 1 As shown, it includes a socket monitoring unit, an identity authentication unit, and a back-end management unit sandwiched between the socket and the plug.

[0022] The identity authentication unit uses Radio Frequency Identification (RFID) technology for identity authentication and uploads the identification results to the backend management unit. Specifically, the identity authentication unit includes an electronic tag that records identity information and a reader / writer that reads the ID information within the electronic tag, enabling the reader / writer to communicate with the backend management unit via a communication module. The specific identity authentication process is as follows: Each reader / writer corresponds to several sockets. Before and after a plug is connected, a person with power access wears an electronic tag and approaches the reader / writer corresponding to the socket. The reader / writer uploads the identified ID information and the reading time to the backend management unit. The time period between the same ID information uploaded by the same reader / writer is defined as the power consumption window period. During the power consumption window period, the electrical equipment connected to the socket corresponding to the reader / writer is marked as internal equipment, and the electrical equipment connected outside the power consumption window period is marked as external equipment.

[0023] One embodiment of this application is: the communication module can perform wireless or wired communication, and the electronic tag can be a passive tag or an active tag.

[0024] Taking a hospital environment as an example, the specific working process of the identity authentication unit is as follows: The reader is set up at the ward entrance. Hospital staff bring medical equipment and electronic tags into the ward. The electronic tag is brought close to the reader, which reads the ID information in the electronic tag and uploads it. The backend management unit matches the received ID information with the ID database. If the match is successful, the power consumption window opens. At this time, any electrical device connected to the socket in that ward is marked as an electrical device, and the backend management unit does not issue a warning or forcibly cut off the power supply to the socket. If the match fails, the power consumption window fails to open, and the reader broadcasts a voice reminder. If an electrical device is connected to the socket in that ward at this time, the backend management unit marks the electrical device as an external device, does not issue a warning, and cuts off the power supply to the external device during peak periods of medical equipment power consumption in the ward.

[0025] When hospital staff leave the ward, the reader reads the ID information in the electronic tag and uploads it. The back-end management unit matches the ID information. If the match is successful and the number of successful matches for the ID information uploaded by the reader is even, the power consumption window is closed. If the match fails, the power consumption window is not closed.

[0026] One embodiment of this application is as follows: the reader is set up at the door of the ward. After the reader completes the authorization authentication, it automatically expands the sensing range of the reader (within tens of centimeters). When hospital staff leave the door with the electronic tag, the authorization authentication is automatically closed and the sensing range of the reader automatically shrinks (within a few centimeters).

[0027] The socket monitoring unit includes an edge control module that is connected to a ranging module, a power consumption monitoring module, a wireless communication module, and a power failure module. The edge control module determines whether a plug is connected to the socket based on the sampling data from the ranging module and the power consumption monitoring module, and uploads the plug identification information to the backend management unit. The backend management unit controls the power failure module to operate based on the type of electrical equipment and the output power of the socket.

[0028] The ranging module includes a ranging sensor that continuously monitors the distance between the socket and an object in front of it. The ranging sensor is connected to an edge control module to transmit the distance value. One embodiment of this application describes a ranging sensor that can be a laser ranging sensor, an ultrasonic ranging sensor, or an infrared ranging sensor. The distance between the socket and the object in front of it determines whether a socket is connected.

[0029] The power monitoring module includes a voltage acquisition circuit, a current sampling circuit, a signal processing circuit, and an analog-to-digital converter (ADC). The voltage acquisition circuit and the current sampling circuit are both connected to the input of the signal processing circuit. The output of the signal processing circuit is connected to the edge control module via the ADC, transmitting the acquired current and voltage signals together to the edge control module. In one embodiment of this application, when the control chip in the edge control module has a built-in ADC, both the voltage acquisition circuit and the current sampling circuit are directly connected to the ADC interface of the control chip via the signal processing circuit.

[0030] The edge control module continuously acquires distance data from the ranging module and current and voltage data from the power consumption monitoring module to monitor whether any electrical devices are connected to the socket. Since the socket's power consumption is not zero when the connected electrical device is in standby mode, an external device must be connected to the socket when the socket's output power is not zero.

[0031] The edge control module has an access identification strategy to determine whether an external device is connected to the socket: it determines whether the socket's power consumption is 0. If no, it provides access feedback that the socket is plugged in. If yes, it continuously acquires several distance values ​​at different positions of the measuring point on the plug contact surface, and determines whether the following conditions are met simultaneously: the root mean square deviation of the distance values ​​at several consecutive sampling times meets the first threshold, the mean of the distance values ​​in the last frame is lower than the second threshold, and the socket's power consumption changes abruptly. If yes, it provides access feedback that the socket is plugged in; if no, it provides access feedback that the socket is not plugged in.

[0032] One embodiment of this application is as follows: when the mean square error of the distance value at continuous sampling time does not meet the first threshold and the mean value of the distance value of the last frame is not lower than the second threshold, but the power consumption of the socket changes suddenly, the edge control module provides access feedback that the socket has a leakage fault.

[0033] The principle behind this strategy is as follows: All plugs on the market have flat contact surfaces. When the plug's pins are aligned with the socket's holes, and the plug is inserted into the hole, the plug's contact surface is parallel to the socket's mounting surface. Under normal circumstances, the calculated standard deviation (SD) is 0. When the plug's contact surface has raised or recessed markings, the SD is slightly greater than 0. Therefore, the first threshold can be set to a value slightly greater than 0. When several consecutive SDs meet the first threshold, it indicates that a flat surface is parallel to and close to the socket's mounting surface. Combined with the socket's power consumption and the distance between the flat surface and the socket, it can be accurately determined whether a socket is connected.

[0034] One embodiment of this application is as follows: when it is a two-hole socket, the measuring points are arranged in a straight line and the arrangement direction is parallel to the arrangement direction of the two holes; when it is a three-hole socket, the measuring points do not need to be arranged in a straight line.

[0035] The wireless communication module includes a WIFI communication unit, which is used to upload the socket's current information, voltage information, power information, access feedback, and socket monitoring unit IP information to the backend management unit. The socket monitoring unit IP information is used to locate specific sockets so that the backend management unit can monitor and manage sockets in batches.

[0036] The back-end control unit determines the power level of the corresponding socket based on the power range of the power information. The power levels are arranged from low to high as the first power level, the second power level, ... the Nth power level. The higher the power consumption, the higher the power level.

[0037] The backend management unit determines the power consumption window period based on the reader IP, ID information and reading / writing time uploaded by the identity authentication unit, and issues backend warnings based on the power consumption level of the internal devices of the power-consuming equipment connected within the power consumption window period and the external devices of the power-consuming equipment connected outside the power consumption window period.

[0038] The backend management unit has a power consumption control strategy to ensure the normal operation of medical equipment by disconnecting the power supply to several private devices during peak power consumption periods. The power consumption control strategy includes: obtaining the apparent power of the upstream node of the socket within the power supply network and comparing it with the upper limit power of that upstream node to generate the node load rate. When node load rate When the corresponding upper limit threshold is exceeded (when a new internal device is connected or the power of the connected internal device increases). Obtain the current power consumption level L and access duration S of all external devices corresponding to the upstream node. Determine the power consumption score P of each external device based on the formula P=(L×u1+S×u2). Sequentially eliminate the external devices with the largest power consumption score P until the node load rate is reached. It is below the corresponding upper limit threshold.

[0039] The specific implementation process and beneficial effects of this application plan are as follows: Example 1: In scenarios such as student dormitories, construction sites, nursing homes, archives, libraries, banks, and worker dormitories, no high-power electrical appliances are allowed to be plugged into sockets. In this case, there is no need to install an authentication unit. The backend management unit directly monitors the power level of the sockets based on the IP information, access feedback, and power information uploaded by the socket monitoring unit. Once it detects that the power consumption of a socket exceeds its rated level, it locks the specific socket based on the monitoring unit information and issues an alarm signal to remind someone to check the situation, or actively cuts off the power supply to the socket until the socket monitoring unit reports "no plug connected to the socket."

[0040] Example 2: In scenarios such as hospital wards and industrial parks, it is not necessary to completely eliminate the connection of external devices. However, excessive external device connections can affect the operational performance of medical and industrial equipment. Therefore, it is necessary to flexibly remove some external devices that affect the normal operation of medical and industrial equipment. In such scenarios, an identity authentication unit is set up to authenticate the medical and industrial equipment before and after its connection. The backend management unit, based on the power consumption window formed by the time difference of identity authentication, locks and distinguishes between internal and external devices. When the power consumption of internal devices increases or when new internal devices are connected, it automatically cuts off several external devices with a significant impact. Subsequently, when the backend management unit continues to detect new external device connections, it directly cuts off the power supply to the corresponding socket until the node load rate of the upstream node corresponding to the socket reaches a certain level. External devices are allowed to connect only when the device's data is below the lower threshold.

[0041] Example 3: To prevent external personnel from removing the socket monitoring unit from the corresponding socket and causing the power monitoring module to idle and evade detection, a motion sensor connected to the edge control module and a miniature battery that temporarily powers the entire socket monitoring unit can be installed inside the socket monitoring unit. When the external power supply to the socket monitoring unit is interrupted or the motion sensor detects that the movement speed of the socket monitoring unit exceeds the threshold, the edge control module uploads the above information and the status of the socket monitoring unit to the background management unit through the wireless communication module and alarms, reminding personnel to check the situation.

[0042] One embodiment of this application involves replacing the motion sensor with a self-resetting switch. The specific principle is as follows: a self-resetting (travel) switch is sandwiched between the socket monitoring unit and the socket. When the socket monitoring unit is fully in contact with the socket, the self-resetting switch is activated. When the distance between the socket monitoring unit and the socket exceeds a threshold, the switch is released or triggered, causing the self-resetting switch to return to the open state. This sends a signal indicating that the socket monitoring unit has been removed, along with the IP information of the socket monitoring unit, to the backend control unit, alerting monitoring personnel to check the situation.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
