Detailed Implementation
[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0017] like Figure 1-2This utility model discloses a remote power acquisition and alarm device for mutual inductance power. The device includes a first voltage and current acquisition module 1, a second voltage and current acquisition module 2, a microcontroller module 3, a wireless transmission module 4, a mains switch 5, a backup battery 6, a remote monitoring terminal 7, and an anomaly monitoring component 8. The first voltage and current acquisition module 1 is installed on the power supply line from the mains to the distribution box, the second voltage and current acquisition module 2 is installed on the power supply line from the distribution box to each electrical device, the mains switch 5 is installed on the power supply line from the mains to the distribution box, the backup battery 6 is connected to each electrical device, and the backup battery 6 is also connected to the mains. The output terminals of the first voltage and current acquisition module 1, the second voltage and current acquisition module 2, and the anomaly monitoring component 8 are connected to the input terminal of the microcontroller module 3. The output terminal of the microcontroller module 3 is connected to the mains switch 5 and the backup battery 6, and the output terminal of the microcontroller module 3 is also connected to the remote monitoring terminal 7 through the wireless transmission module 4. The first voltage and current acquisition module 1 includes a first current transformer 101 and a first voltage transformer 102. The first current transformer 101 and the first voltage transformer 102 are installed on the power supply line from the mains to the distribution box. The first current transformer 101 and the first voltage transformer 102 collect the voltage and current on the power supply line from the mains to the distribution box, and the total power supply can be obtained based on the voltage and current data. The second voltage and current acquisition module 2 includes a second current transformer 201 and a second voltage transformer 202. The second current transformer 201 and the second voltage transformer 202 are installed on the power supply line from the distribution box to each electrical device. Multiple second current transformers 201 and second voltage transformers 202 are used, each installed on the power supply line of each electrical device, collecting its voltage and current. The total power consumption of the device can be obtained based on the voltage and current data. The total power supply is compared with the total power consumption of the device. If the difference is within the normal range, the power supply is normal and there is no electricity theft. If the difference exceeds the normal range, the power supply is abnormal and there may be electricity theft. The microcontroller module, such as a microcontroller, transmits abnormal power information to the remote monitoring terminal via a wireless transmission module to trigger an alarm, alerting staff to promptly check and address the anomaly. The wireless transmission module uses one or more of 4G / 5G or LoRa wireless communication modules to ensure timely and effective data transmission. The remote monitoring terminal is a computer. When an abnormal power supply is detected, indicating potential electricity theft, the mains power supply can be cut off via a control switch, activating the backup battery to temporarily power the devices, reducing the amount of electricity stolen and minimizing losses. All monitoring devices in this system are powered by mains power; after a mains power outage, they are powered by the backup battery. The backup battery is charged via mains power. The anomaly detection component can monitor whether the distribution box has been illegally opened, preventing electricity theft. Through the comprehensive use of multiple monitoring methods, various forms of electricity theft can be accurately and promptly detected, effectively reducing economic losses. Upon detecting electricity theft, an alarm signal is immediately issued, enabling relevant personnel to take timely measures to stop the theft and minimize losses.
[0018] The anomaly monitoring component 8 includes a tilt sensor 801 and a vibration sensor 802, both mounted on the door of the distribution box. The outputs of the tilt sensor 801 and vibration sensor 802 are connected to the input of the microcontroller module 3. The tilt sensor and vibration sensor monitor whether the distribution box door is open. If the door is opened, the angle will change significantly, and the tilt sensor can detect this change and trigger an alarm. The vibration sensor determines abnormal activity by sensing the mechanical vibration frequency and amplitude of an object. When the distribution box door is pried open or forcibly opened, vibration will occur at the connection between the door and the box (such as hinges or latches). The vibration sensor can detect this non-periodic vibration signal and trigger an alarm. When the door is detected to be open, the tilt sensor and vibration sensor send the monitoring information to the microcontroller module, which then sends the information to the verification component, reminding personnel to perform verification.
[0019] The remote power acquisition and alarm device for mutual inductance also includes a verification component 9, which comprises an indicator light 901 and a password authenticator 902. The indicator light 901 and password authenticator 902 are installed inside the distribution box and are connected to the microcontroller module 3. When the box door is detected to be open, the tilt sensor and vibration sensor send monitoring information to the microcontroller module, which then sends the information to the verification component. This causes the indicator light to illuminate, reminding staff to enter the password for verification via the password authenticator. Simultaneously, the microcontroller in the microcontroller module starts a timer. If the password is correct within the specified time, verification is successful, and the indicator light turns off, reducing false alarms. If the correct password is not entered within the specified time, verification fails, indicating that the distribution box door has been illegally opened. The microcontroller module then sends the information to the remote monitoring terminal to trigger an alarm, alerting staff to the abnormality and prompting timely action.
[0020] The remote power acquisition and alarm device for mutual inductance also includes a locator 10, which is installed on the distribution box and connected to the microcontroller module 3. When an abnormal power level is detected, indicating possible electricity theft, the locator can be used to locate the distribution box, facilitating timely identification and handling of the anomaly.
[0021] The remote power acquisition and alarm device for mutual inductance also includes a speaker 11, which can be installed on the distribution box and is connected to the microcontroller module 3. When an abnormality is detected, indicating possible electricity theft, the microcontroller module controls the speaker to sound, such as "Electricity theft is illegal, please stop operating," to warn the electricity thief or nearby personnel, so that staff can arrive in time to handle the situation.
[0022] Work process:
[0023] The working principle of this utility model is as follows: The first current transformer 101 and the first voltage transformer 102 collect the voltage and current on the power supply line from the mains to the distribution box. The total power supply can be obtained based on the voltage and current data. Multiple second current transformers 201 and second voltage transformers 202 are installed on the power supply lines of each electrical device, collecting their voltage and current. The total power consumption of the device can be obtained based on the voltage and current data. The total power supply is compared with the total power consumption of the device. If the difference is within the normal range, the power supply is normal, and there is no electricity theft. If the difference exceeds the normal range, the power supply is abnormal, and electricity theft may exist. The microcontroller module 3 transmits abnormal power information to the remote monitoring terminal 7 via the wireless transmission module 4 to trigger an alarm, reminding staff to promptly check and handle the abnormality. When the distribution box door is detected to be open, the tilt sensor 801 and vibration sensor 802 send monitoring information to the microcontroller module 3. The microcontroller module 3 then sends the information to the verification component 9, causing the indicator light 901 to illuminate, reminding staff to enter the password through the password verifier 902 for verification. If the password is correct within the specified time, the verification is successful, and the indicator light 901 turns off, reducing false alarms. If the correct password is not entered within the specified time, the verification fails, indicating that the distribution box door has been illegally opened. The microcontroller module 3 then sends the information to the remote monitoring terminal 7 to trigger an alarm, alerting staff to the abnormality and prompting timely action.
