Description

Technical Field

[0001] This utility model relates to the field of metering box technology, specifically an Internet of Things metering box based on fingerprint monitoring of electricity consumption and unlocking. Background Technology

[0002] As an indispensable piece of equipment in the power industry, metering boxes play an important role in measuring and storing electricity. With the continuous development of Internet of Things (IoT) technology, IoT metering boxes, as a type of intelligent metering device, have been widely used in the power sector.

[0003] Traditional metering boxes typically use mechanical locks for encryption protection. However, mechanical locks are not convenient to use, cannot be integrated with IoT technology, and are prone to key loss. If the key is obtained by someone else, there is a risk of unauthorized opening of the metering box.

[0004] To ensure the security and convenience of using IoT metering boxes, fingerprint monitoring unlocking technology has been incorporated into the boxes. Since everyone's fingerprints are unique, fingerprint monitoring can effectively prevent unauthorized personnel from using or tampering with electrical equipment, thus improving the security of the metering boxes. At the same time, with fingerprint monitoring technology, users do not need to carry or keep keys, and fingerprint recognition is simpler and faster, improving the convenience of using the metering boxes.

[0005] However, using fingerprint monitoring for unlocking also presents new problems. Since fingerprint monitoring requires power, the fingerprint lock will fail in the event of a power outage or power failure, and staff will be unable to open the door of the IoT metering box. In addition, if the door lock is forcibly dismantled or damaged in the event of a power outage, monitoring and alarm functions will be unavailable. Utility Model Content

[0023] The advantages and solutions of this application will become clear to those skilled in the art upon reading the following detailed description of preferred embodiments. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this invention.

[0024] In the attached diagram:

[0025] Figure 1 This is a schematic diagram of the structural composition of an IoT metering box system based on fingerprint monitoring of electricity consumption and unlocking, as shown in the embodiment. Detailed Implementation

[0026] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0027] Example

[0028] This embodiment provides an IoT metering box based on fingerprint monitoring of electricity consumption and unlocking. See [link to documentation]. Figure 1 It includes a controller, power module, alarm module, relay, and power consumption circuit module located inside the IoT metering box housing, as well as a fingerprint lock module and monitoring module installed on the IoT metering box door.

[0029] The power supply module is electrically connected to the controller. The fingerprint lock module, monitoring module, and alarm module are connected in parallel and then electrically connected to the controller. A relay is connected in parallel in the connection circuit between the fingerprint lock module, monitoring module, alarm module, and controller. The power consumption circuit module is connected in parallel in the connection circuit between the relay and controller.

[0030] The relay is electrically connected to a backup power supply.

[0031] Specifically, in this embodiment, the controller is the core of the IoT metering box system based on fingerprint monitoring of electricity consumption and unlocking. It is located inside the IoT metering box shell and is responsible for receiving data from other modules in the IoT metering box, including fingerprint recognition data, monitoring data, alarm data, power data, and circuit switching data. At the same time, it sends data instructions to each module. The controller can be a microcontroller controller.

[0032] The output of the power module is electrically connected to the power input of the controller. Under normal circumstances, the power module is connected to the power supply line to convert the external AC power into stable DC power, and then provide power support for the controller and various modules to ensure the normal operation of the IoT metering box.

[0033] The fingerprint lock module, monitoring module, and alarm module are connected in parallel and then electrically connected to the controller. The fingerprint lock module is installed on the door of the IoT metering box and is used to unlock the box after successful fingerprint verification. The fingerprint lock module includes a fingerprint recognition unit and an electronic lock electrically connected to each other. The electronic lock is electrically connected to the controller. In this embodiment, the fingerprint recognition unit is a touch sensor, model FPC1020. The FPC1020 touch sensor is based on the principle of capacitive sensing. It acquires the user's fingerprint image through an internal capacitor array and transmits the fingerprint image to the controller. The controller receives the fingerprint image and, upon successful fingerprint verification, sends an unlocking command to the electronic lock. The electronic lock unlocks, and the door of the IoT metering box opens. The electronic lock model can be a YLI-280W motor lock.

[0034] The monitoring module is installed on the door of the IoT metering box to monitor its status in real time and acquire monitoring data. The monitoring module includes a vibration monitoring unit and an acceleration monitoring unit, both electrically connected to the controller. The vibration monitoring unit can be an LDT0-028K piezoelectric vibration sensor to acquire vibration data from the IoT metering box door in real time; the acceleration monitoring unit can be an MPU6050 triaxial accelerometer to acquire acceleration data from the IoT metering box door in three axial directions in real time. The acquired vibration and acceleration data are transmitted to the controller. If the monitored data value exceeds a normal threshold, the controller sends a command to the alarm module to trigger an alarm.

[0035] The alarm module is used to issue alarm signals. The alarm module includes an LED light and a buzzer. When the alarm module receives an alarm command from the controller, the LED light flashes and the buzzer sounds an alarm.

[0036] A relay is connected in parallel in the connection circuit between the fingerprint lock module, monitoring module, alarm module, and controller. This relay is used to switch to the backup power supply in the event of a power outage or power failure, ensuring continuous power to the fingerprint lock module, monitoring module, and alarm module. In this embodiment, an 8-pin relay is used. Pins 13 and 14 are coil pins, connected to the controller; pins 9 and 12 are common pins, connected to the backup power supply; pins 1 and 4 are normally closed pins, connected to the fingerprint lock module, monitoring module, and alarm module respectively; pins 5 and 8 are normally open pins, connected to the fingerprint lock module, monitoring module, alarm module, and power consumption circuit module respectively. Under normal conditions, pins 5 and 8 are normally open, and the remaining pins of the relay are closed, supplying power to the power module. When there is a power outage or power failure, pins 13 and 14 automatically open, triggering pins 1 and 4 to open and pins 5 and 8 to close, thus completing the conductive circuit of the backup power supply. At this time, the power supply switches to the backup power supply for the fingerprint lock module, monitoring module, and alarm module. The backup power supply can be a battery.

[0037] The power consumption circuit module is connected in parallel to the connection loop between the relay and the controller. This module powers the controller after switching to the backup power supply, ensuring the normal operation of the IoT metering box. For example... Figure 1 As shown, the power consumption circuit module includes a voltage VCC, which is connected to the emitter (e) of transistor Q1. The collector (c) of transistor Q1 is connected to the controller and one end of resistor R3. The other end of resistor R3 is connected to the controller and one end of diode D2. The other end of diode D2 is connected to the input terminal A of the activation switch P. VCC is also connected to one end of resistor R1. The other end of resistor R1 is connected to the base (b) of transistor Q1 and one end of resistor R2. The other end of resistor R2 is connected to the collector of transistor Q2. c. One end of diode D1 and the other end of diode D1 are connected to the input terminal A of the activation switch P. The emitter e of transistor Q2 is grounded. The base b of transistor Q2 is connected to one end of resistor R4 and one end of resistor R5 respectively. The other end of resistor R4 is connected to the controller. The other end of resistor R5 is connected to the emitter e of transistor Q2. The input terminal A of activation switch P is connected to diodes D1 and D2 respectively. The output terminal B of activation switch P is grounded. The control output terminal C of activation switch P is connected to pins 5 and 8 of the relay.

[0038] Under normal power supply conditions, the circuit containing the activation switch P is not conductive, and the power consumption circuit module is in sleep mode. The controller is powered by the power supply module. After switching to backup power, the circuit containing the activation switch P is energized. The activation switch P is a magnetic latching relay, which closes after being energized. At this time, the entire power consumption circuit module is activated, and the controller can work normally. Specifically, the voltage VCC in the power consumption circuit module flows sequentially through resistor R1, the base-eb terminal of transistor Q1, resistor R2, diode D1, and activation switch P to the ground terminal GND. Driven by the current, transistor Q2 is turned on, and the controller is powered on. Then, the controller sends a signal sequentially through diode D2 and activation switch P to the ground terminal GND. When the controller receives the signal that activation switch P is closed, it outputs a high-level signal through the output pin. The high-level signal flows sequentially through resistor R4 and the base-eb terminal of transistor Q2 to the ground terminal GND, driving transistor Q2 to lock and continuously supply power to the controller, ensuring the normal operation of the IoT metering box after a power outage.

[0039] This utility model provides an IoT metering box based on fingerprint monitoring for power consumption and unlocking. In the event of a power outage or power failure, a relay switches to a backup power source to ensure the normal unlocking of the IoT metering box and to ensure continuous monitoring of the IoT metering box, thereby improving the security and convenience of its use. A power consumption circuit module is also included to power the controller when the backup power source is activated, ensuring the normal operation of the IoT metering box.
