In one embodiment, the electrical property value detection module 13 includes: a hall sensor 131 arranged between the input terminal 11 and the output terminal 12 for generating an alternating voltage signal corresponding to an alternating current based on a hall effect; a 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 voltage value of a digital quantity; a conversion module 142, configured to convert the voltage value of the digital quantity into a digital quantity current value of an alternating current; the sending module 143 is configured to send a notification message including an identifier of the electric device and a digital value of the alternating current.
The hall sensor 131 is a magnetic field sensor made according to the hall effect. The hall effect is essentially the deflection of moving charged particles in a magnetic field caused by the action of lorentz forces. When charged particles (electrons or holes) are confined in a solid material, this deflection results in the accumulation of positive and negative charges in the direction of the perpendicular current and magnetic field, thereby creating an additional transverse electric field. The output voltage of the hall sensor 131 is linearly related to the intensity of the applied magnetic field. Specifically, the hall sensor 131 includes a hall element, a linear amplifier, and an emitter follower for outputting an alternating voltage signal of an analog quantity corresponding to the alternating current.
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 a magnetic field exists inside the energized solenoid, the magnitude of which is proportional to the current in the wire, the hall sensor 131 can be used to measure the magnetic field, thereby determining the magnitude of the current in the wire (i.e., the alternating current between the input terminal 11 and the input terminal 12). The open-loop Hall current sensor has the advantages of no electric contact with a tested circuit, no influence on the tested circuit, no consumption of the power of a tested power supply and particular suitability for large-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, a magnetic field generated by the current Ip to be measured in the main loop at the magnetic convergence ring is compensated by a secondary coil, so that the hall device is in an operating state of detecting zero magnetic flux. The specific working process of the closed-loop Hall current sensor is as follows: when current (namely alternating current between the input end 11 and the input end 12) passes through the main loop, a magnetic field generated on the lead Is gathered by the magnetic gathering ring and Is induced to the Hall device, and a generated signal output Is used for driving a corresponding power tube and conducting the power tube, so that the compensation current Is obtained. The compensation current Is generates a magnetic field through the multi-turn winding, and the magnetic field Is just opposite to the magnetic field generated by the measured current, so that the original magnetic field Is compensated, and the output of the Hall device Is gradually reduced. When the magnetic field Is equal to the magnetic field generated by multiplying Ip by the number of turns, Is does not increase any more, and the hall device acts to indicate zero flux.
The above exemplary description describes a typical example of detecting current based on the hall sensor 131, and those skilled in the art will appreciate that this description is merely exemplary and is not intended to limit the scope of the embodiments of the present invention.
The shaping module 132 is configured to shape the ac voltage signal generated by the hall sensor 131 into a dc voltage signal. Then, the analog-digital conversion module 141 in the communication module 14 converts the direct-current voltage signal into a voltage value of a digital quantity. The converting module 142 is configured to convert the voltage value of the digital quantity into a current value (e.g., an effective value) of the digital quantity, where the current value of the digital quantity is a current value of the alternating current between the input terminal 11 and the input terminal 12. The transmitting module 143 then transmits a notification message containing the identification of the powered device and the digital amount of the current value to a device management system located remotely or locally or to a mobile terminal held by the user.
After the equipment management system or the mobile terminal receives the notification message, the identification of the electric equipment and the current value of the digital quantity are analyzed from the notification message. The device management system or the mobile terminal can confirm the identity of the user equipment based on the identification of the electric equipment. Also, the device management system or the mobile terminal may perform various secondary processes (e.g., statistics of history data, calculation of power consumption, etc.) on the current value, so that the operating condition of the user equipment (e.g., total operating time, peak operating time, total power consumption, maximum instantaneous power consumption, etc.) may be further understood.
In one embodiment, the message sending unit 10 further includes: a geographic position determination module 18 for determining geographic position information of the message sending unit 10; the communication module 14 is configured to send a notification message including the identification of the electric device, the current value, and the geographical location information. The geographic position determination module 18 may, among other things, actively determine the geographic position information of the messaging unit 10 based on an indoor geographic position detection function and/or an outdoor geographic position detection function. The geographic location determination module 18 may also access the storage medium to obtain geographic location information for the messaging unit 10. For example, the storage medium may include: a storage medium in the message sending unit 10, or a storage medium in a power supply connected to the input 11, or a storage medium in a consumer connected to the output 12, etc.
Specifically, the geographical location information includes at least one of: global positioning system coordinates; beidou satellite navigation system coordinates; glonass satellite navigation system coordinates; building identification; identifying a floor; a room identification; and so on.
For example, when it is desired to detect the outdoor geographic position of the message sending unit 10, the geographic position determining module 18 may adopt a beidou satellite navigation mode, a GPS satellite navigation mode, a galileo satellite navigation mode, or a glonass satellite navigation mode, etc. to achieve outdoor positioning for the detection message 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 determining module 18 may determine a Wi-Fi positioning technology, a bluetooth positioning technology, an infrared positioning technology, an ultra wideband positioning technology, an RFID positioning technology, a ZigBee (ZigBee) positioning technology, an ultrasonic technology, or the like, so as to achieve indoor positioning for the detection message sending unit 10.
As another example, when it is desired to determine floor information of the message sending unit 10, the geographic position determination module 18 may access its own storage medium to acquire a building identification, a floor identification, and a room identification, which are stored in the storage medium in advance, 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) communications, Bluetooth or ZigBee, etc.
While the above exemplary descriptions describe typical examples of geographic location detection techniques and communication protocols, those skilled in the art will appreciate that such descriptions are merely exemplary and are not intended to limit the scope of embodiments of the present invention.
