When the mobile phone prototype positioning method is applied, the positioning label sends a positioning signal to the positioning base station, and the positioning base station receives the positioning signal and sends the positioning signal to the background for processing, so that the position of the mobile phone prototype is determined.
Because the power supply is arranged in the positioning label, the size of the positioning label is overlarge.
SUMMERY OF THE UTILITY MODEL
The embodiment of the utility model provides a location label and positioning system can solve the too big problem of prior art location label size. The technical scheme is as follows:
in one aspect, there is provided a positioning tag, comprising:
a housing;
the control module and the signal sending module are positioned in the shell;

In addition, the positioning tag can be an ultra-wideband positioning tag and can send a positioning signal of a narrow pulse type to a positioning base station.
Through the arrangement, the terminal device transmits electric energy to the control module through the interface, and the control module triggers the signal sending module to send a first positioning signal to the positioning base station under the action of the electric energy. And the positioning base station sends the first positioning signal to a background for processing so as to obtain the position information of the positioning label, and then the position information of the terminal equipment connected with the positioning label can be determined so as to realize wireless theft prevention of the terminal equipment.
In one possible design, the positioning tag further comprises: a charging module on the housing, the charging module electrically coupled to the control module;
the charging module is used for outputting electric energy to the terminal equipment through the control module.
Through the arrangement, the terminal equipment can be directly charged without pulling the positioning tag out of the interface of the terminal equipment.
In one possible design, the positioning tag further comprises: the detection module and the switching module are positioned in the shell;
the detection module is electrically coupled with the control module and the switching module respectively, and is used for detecting the level state of the control module and transmitting a detection result to the switching module;

It should be noted that the interface between the interface and the terminal device may be a USB Type C interface with a DRP (dual role port, chinese full name) port. The port role of the interface can be switched between a DFP (downlink port, chinese name) and a UFP (uplink port, english name), that is, the operating mode of the interface is switched between a power supply mode and a power taking mode. When the port role of the interface is DFP, the interface is used as a power supply side; when the port role of the interface is UFP, the interface is used as a power-taking party.
By the above arrangement, when the interface of the positioning tag is electrically coupled only with the interface of the terminal device and is not electrically coupled with the external power supply through the charging module, the detection module of the positioning tag detects that the control module is in a low level state, and then transmits the detection result to the switching module. The switching module switches the CC1 port and the CC2 port of the interface to be connected with self Rd resistance (namely pull-down resistance corresponding to low level) according to the detection result, at the moment, the port role of the interface is UFP specifically, namely, the working mode of the interface is the power taking mode. At this time, the CC1 port and the CC2 port on the terminal device interface detect that the terminal device interface is electrically coupled to the Rd resistor of the interface of the location tag, and then the terminal device interface connects the CC1 port and the CC2 port of the terminal device interface with the Rp resistor of the terminal device interface (i.e., the pull-up resistor corresponding to a high level), so that the terminal device interface enters a DFP state, and then the terminal device interface opens the Vbus port of the terminal device interface, and supplies power to the control module of the location tag through the interface of the location tag.
When the interface of the positioning tag is electrically coupled with the interface of the terminal device and is electrically coupled with the external power supply through the charging module, the detection module of the positioning tag detects that the control module is in a high level state, and then transmits a detection result to the switching module. The switching module switches a CC1 port and a CC2 port of the interface to be connected with an Rp resistor of the interface according to a detection result, at the moment, the role of the port of the interface is specifically DFP, then the interface opens a Vbus port on the interface and supplies power to the terminal equipment, namely, the working mode of the interface is a power supply mode. At this time, the CC1 port and the CC2 port on the terminal device interface detect that the terminal device interface is electrically coupled with the Rp resistor connected to the positioning tag, and then the terminal device interface connects the CC1 port and the CC2 port of the terminal device interface with the Rd resistor of the terminal device interface, so that the terminal device interface enters the UFP state, and the electric energy output by the charging module is obtained through the interface of the positioning tag.
When the charging module passes through the control module of the positioning tag and outputs electric energy to the terminal equipment, the electric energy acquired by the charging module is divided into two paths at the control module, one path of electric energy is acquired by the control module, the other path of electric energy is transmitted to the interface through the control module, and then transmitted to the interface established by the terminal through the interface and received by the terminal equipment.

Wherein, interface structure can set up to USBType A interface, USBType B interface or USBType C interface according to the precious USB interface Type that charges.
In addition, in order to facilitate the operator to distinguish the interface from the charging module, an identification area may be disposed on the outer wall of the housing, for example, the identification area may be configured as a mark symbol, a bump, or a groove.
When the charging module is in a charging plug structure, the external power supply corresponding to the charging module in the structure is in a jack structure electrically coupled with mains supply, and because the charging module provided by the example is different from the interface structure of the positioning tag, an operator can distinguish the interface from the charging module conveniently, and the terminal equipment can be charged in time.
The charging module comprises two metal conducting plates, one metal conducting plate is used as a positive electrode, the other metal conducting plate is used as a negative electrode, one end of each metal conducting plate is electrically coupled with the interface, and the other end of each metal conducting plate is located outside the shell.

If the boss is not arranged on the shell, the whole shell is inserted into a power supply port of a charging seat with the size not much different from that of the USB interface, so that the difficulty of the positioning label is increased, and the processing of the positioning label is not facilitated.
The connection mode between the boss and the body can be set to be bonding or integrated, and the latter can be preferentially adopted based on the characteristic of high connection strength.

And the positioning base station sends a part of the first positioning signals to a background for processing so as to obtain the position information of the positioning label, and further can determine the position information of the terminal equipment connected with the positioning label. Meanwhile, the positioning base station transmits another part of the first positioning signal (i.e. a third positioning signal) to the signal sending module, the signal sending module sends the received third positioning signal to the control module, the control module processes the third positioning signal according to the received third positioning signal to calculate the position information of the positioning tag, and then the processing result is sent to the terminal device through the interface of the positioning tag.

When the interface 14 of the positioning tag 100 is electrically coupled to both the interface of the terminal device a and the external power source through the charging module 15, the detection module 16 of the positioning tag 100 detects that the control module 12 is in the high level state, and then transmits the detection result to the switching module 17. The switching module 17 switches the CC1 port and the CC2 port of the interface to be connected to the Rp resistor of the interface according to the detection result, where the port role of the interface 14 is DFP (see fig. 12), and then the interface 14 opens the Vbus port of the interface to supply power to the terminal device a, that is, the operating mode of the interface 14 is the power supply mode. At this time, the CC1 port and the CC2 port on the interface of the terminal device a detect that the terminal device a is electrically coupled to the Rp resistor of the interface 14 of the positioning tag 100, and then the interface of the terminal device a connects the CC1 port and the CC2 port of the terminal device a to the Rd resistor of the terminal device a, so that the interface of the terminal device a enters the UFP state, and the interface 14 of the positioning tag 100 obtains the electric energy output by the charging module 15.

The positioning base station 200 sends a part of the first positioning signal to the background for processing to obtain the position information of the positioning tag 100, so as to determine the position information of the mobile phone model machine connected with the positioning tag 100. Meanwhile, the positioning base station 200 sends another part of the first positioning signal (i.e., the second positioning signal) to the signal sending module 13, the signal sending module 13 sends the received second positioning signal to the control module 12, and the control module 12 performs processing according to the received second positioning signal to calculate the position information of the positioning tag 100. Then, the control module 12 controls the alarm device 17 to alarm according to the position information. When the mobile phone model machine carrying the positioning label 100 is positioned in the preset electronic fence, the alarm device 17 does not give an alarm; when the mobile phone model machine carrying the positioning label 100 moves to the outer area of the preset electronic fence, the alarm device 17 alarms, such as ringing or vibrating.

It can be understood that the third positioning signal received by the signal sending module 13 refers to the third positioning signal sent by the positioning base station 200, and the third positioning signal and the first positioning signal sent by the signal sending module 13 are the same pulse.
The following description is given of the working principle of the positioning tag 100 structured as above, taking the terminal device a as a prototype of a mobile phone as an example:
when the interface 14 of the positioning tag 100 is inserted into the interface of the mobile phone model machine, the mobile phone model machine transmits electric energy to the signal sending module 13 of the positioning tag 100 through the interface 14 of the positioning tag 100, and the control module 12 triggers the signal sending module 13 to send a pulse to the positioning base station 200 under the action of the electric energy to serve as a first positioning signal. The positioning base station 200 sends a part of the first positioning signal to the background for processing to obtain the position information of the positioning tag 100, so as to determine the position information of the mobile phone model machine connected with the positioning tag 100. Meanwhile, the positioning base station 200 sends another part of the first positioning signal (i.e., the third positioning signal) to the signal sending module 13, the signal sending module 13 sends the received third positioning signal to the control module 12, the control module 12 processes the third positioning signal according to the received third positioning signal to calculate the position information of the positioning tag 100, and then sends the processing result to the mobile phone model machine through the interface 14 of the positioning tag 100. When the positioning tag 100 is positioned in the preset electronic fence, the mobile phone model machine does not give an alarm according to the processing result; when the positioning label 100 moves to the outer area of the preset electronic fence, the mobile phone model machine alarms according to the processing result, such as ringing or vibrating. In addition, when the mobile phone model machine cannot receive the processing result, an alarm is given.

The signal transmitting module 13 is a wireless transceiver chip, and the signal transmitting module 13 not only has a small size, but also has a high data transmission efficiency, and can be set to a transceiver chip with a model number nRF24L01, for example.

when the positioning label is applied, the interface 14 of the positioning label 100 is firstly inserted into the interface of the mobile phone model machine. The mobile phone model machine transmits electric energy to the control module 12 of the positioning label 100 through the interface 14 of the positioning label 100, and the control module 12 triggers the signal sending module 13 to send a first positioning signal to the positioning base station 200 under the action of the electric energy. The positioning base station 200 transmits the first positioning signal to the positioning tag 100.

The processing device 300 processes the received first positioning signal, calculates the position information of the positioning tag 100, and transmits the position information to the display device 400. The display device 400 displays the location of the terminal device a connected to the location tag 100. It can be seen that through the mutual cooperation of the processing device 300, the display device 400 and the positioning base station 200, the backstage personnel can conveniently master the position information of the terminal device a in real time, and can perform dual theft prevention on the terminal device a by combining the positioning function of the positioning tag 100.
The positioning tag 100 may be electrically coupled to the processing device 300 in a wireless manner, which is beneficial for positioning the layout of the base station 200 and the processing device 300.
