The above exemplarily describes typical examples of the AC-DC converter 15 and the DC-DC converter 16, and those skilled in the art can realize that this description is only exemplary, and is not intended to limit the protection scope of the embodiments of the present invention .

In one embodiment, the electrical property value detection module 13 includes: a Hall sensor 131, arranged between the input end 11 and the output end 12, for generating an AC voltage signal corresponding to the alternating current based on the Hall effect; the shaping module 132, For shaping the AC voltage signal into a DC voltage signal; the communication module 14 includes: an analog-to-digital conversion module 141 for converting the DC voltage signal into a digital voltage value; a conversion module 142 For converting the digital voltage value is the digital current value of the alternating current; the sending module 143 is configured to send a notification message including the identification of the electrical equipment and the digital current value of the alternating current.

The Hall sensor 131 is a magnetic field sensor fabricated according to the Hall effect. The Hall effect is essentially the deflection of moving charged particles in a magnetic field by the Lorentz force. When charged particles (electrons or holes) are confined in a solid material, this deflection leads to the accumulation of positive and negative charges in the direction perpendicular to the current and magnetic field, resulting in an additional transverse electric field. The output voltage of the Hall sensor 131 has a linear relationship with the strength of the applied magnetic field. Specifically, the Hall sensor 131 includes a Hall element, a linear amplifier and an emitter follower for outputting an analog AC voltage signal corresponding to the AC power.

For example, the Hall sensor 131 may be implemented as an open-loop Hall current sensor or a closed-loop Hall current sensor.

When the Hall sensor 131 is implemented as an open-loop Hall current sensor, since there is a magnetic field inside the energized solenoid, and its magnitude is proportional to the current in the wire, the Hall sensor 131 can be used to measure the magnetic field to determine the current in the wire (that is, the size of the alternating current between the input terminal 11 and the input terminal 12). The advantage of the open-loop Hall current sensor is that it does not make electrical contact with the circuit under test, does not affect the circuit under test, and does not consume the power of the power supply under test, and is especially suitable for high current sensing.

When the Hall sensor 131 is implemented as a closed-loop Hall current sensor (also referred to as a compensation sensor), that is, the magnetic field generated by the measured current Ip in the main loop at the magnetic concentrating ring passes through a secondary coil, which affects the measured current in the main loop. The magnetic field generated by Ip is compensated, so that the Hall device is in the working state of detecting zero magnetic flux. The specific working process of the closed-loop Hall current sensor is as follows: when the main loop has current (that is, the alternating current between the input terminal 11 and the input terminal 12) passing through, the magnetic field generated on the wire is gathered by the magnetic focusing ring and induced to the Hall device. On the above, the generated signal output is used to drive the corresponding power tube and turn it on, so as to obtain the compensation current Is. The compensation current Is generates a magnetic field through the multi-turn winding, which is just opposite to the magnetic field generated by the measured current, thus compensating the original magnetic field and gradually reducing the output of the Hall device. When the magnetic field is equal to the magnetic field produced by multiplying Ip and the number of turns, Is no longer increases, and the Hall device acts as an indication of zero flux.

The above exemplary description describes a typical example of current detection based on the Hall sensor 131, and those skilled in the art can realize that this description is only exemplary, and is not used to limit the protection scope of the embodiments of the present invention.

The shaping module 132 is used for shaping the AC voltage signal generated by the Hall sensor 131 into a DC voltage signal. Then, the analog-to-digital conversion module 141 in the communication module 14 converts the DC voltage signal into a digital voltage value. The conversion module 142 is used to convert the voltage value of the digital quantity into the current value of the digital quantity (for example, the effective value), and the current value of the digital quantity is the current value of the alternating current between the input terminal 11 and the input terminal 12 . Then, the sending module 143 sends a notification message including the identification of the electrical equipment and the digital current value to the remote or local equipment management system or the mobile terminal held by the user.

After receiving the notification message, the equipment management system or the mobile terminal parses out the identification of the electrical equipment and the current value of the digital quantity. The equipment management system or the mobile terminal can confirm the identity of the user equipment based on the identity of the electrical equipment. Moreover, the device management system or the mobile terminal can perform various secondary processing (such as statistical historical data, calculation of power consumption, etc.) on the current value, so as to further understand the working status of the user equipment (such as the total working time, working time, etc.) peak hours, total power consumption, maximum instantaneous power consumption, etc.).

In one embodiment, the message sending unit 10 further includes: a geographic location determination module 18, configured to determine geographic location information of the message sending unit 10; wherein the communication module 14 is configured to send an identifier including the electrical equipment, the current value and the Notification message for geolocation information. The geographic location determination module 18 may actively determine the geographic location information of the message sending unit 10 based on the indoor geographic location detection function and/or the outdoor geographic location detection function. The geographic location determination module 18 may also access the storage medium to obtain geographic location information of the messaging unit 10 . For example, the storage medium may include: the storage medium in the message sending unit 10, or the storage medium in the power supply connected to the input end 11, or the storage medium of the electrical device connected to the output end 12, and so on.

Specifically, the geographic location information includes at least one of the following: global positioning system coordinates; Beidou satellite navigation system coordinates; GLONASS satellite navigation system coordinates; building identification; floor identification; room identification; and the like.

For example, when it is desired to detect the outdoor geographic location of the message sending unit 10, the geographic location determination module 18 can use the Beidou satellite navigation method, GPS satellite navigation method, Galileo satellite navigation method or GLONASS satellite navigation method, etc. Outdoor positioning of the sending unit 10 .

For another example, when it is desired to detect the indoor geographic location of the message sending unit 10, the geographic location determination module 18 may determine Wi-Fi positioning technology, Bluetooth positioning technology, infrared positioning technology, ultra-wideband positioning technology, RFID positioning technology, ZigBee positioning technology, and Wi-Fi positioning technology. ) positioning technology or ultrasonic technology, etc., to realize indoor positioning for detecting the message sending unit 10 .

For another example, when it is desired to determine the floor information of the message sending unit 10, the geographic location determination module 18 may access its own storage medium to obtain the floor identification and room identification pre-stored in the storage medium from the storage medium.

Moreover, the communication protocol used by the communication module 14 to send the notification message includes but is not limited to: Wi-Fi, cellular mobility (2G, 3G, 4G, 5G, NB-IOT) communication, Bluetooth or ZigBee, and so on.
