The shopping cart positioning tag 100 provided by the embodiment of the invention can be installed on a shopping cart 400, the shopping cart 400 can be accurately positioned by utilizing the accurate positioning function of the UWB positioning module 102, and the obtained indoor position information of the shopping cart 400 can be sent to the user terminal 300 through the near field communication unit 103, so that the user can check the current position of the user, and the user can conveniently judge the relative position and distance of the commodity according to the current position of the user, therefore, the shopping efficiency of the user can be improved, the physical burden of shopping of the user is reduced, and the shopping experience is improved.
Illustratively, referring to fig. 5 and 6, fig. 5 is a circuit diagram of the control unit 104 integrated with a bluetooth chip, and the chip model of the control unit 104 is NRF 52832. Fig. 6 is a circuit diagram of the UWB positioning module 102, the chip model of the UWB positioning module 102 is DW1000, the control unit 104 and the UWB positioning module 102 are connected to each other through terminals with the same identifier, for example, a terminal identified as P027_ UWB _ IRQ on the control unit 104 is connected to a terminal also identified as P027_ UWB _ IRQ on the UWB positioning module 102, and the connection relationship between the terminals is specifically shown in fig. 3 and fig. 4, so that the UWB positioning module 102 is connected to the control unit 104, and the control unit 104 and the UWB positioning module 102 with the above structure have the advantages of high integration level, simple circuit structure and reliable performance.
Referring to fig. 1-2, in some embodiments of the present invention, the shopping cart further comprises a falling-off detection unit 105 and a remote communication unit 106, wherein the falling-off detection unit 105 is connected to the control unit 104 for generating a trigger signal when the housing 101 is separated from the shopping cart 400. The remote communication unit 106 is connected to the control unit 104, and is configured to send a drop prompt message to the server 200 according to the trigger signal.
In the practical use of the shopping cart 400, the shopping cart 400 is difficult to avoid collision, which may cause the problem that the shopping cart positioning tag 100 falls off, and the shopping cart 400 loses the positioning function after the shopping cart positioning tag 100 falls off.
For this purpose, in the present embodiment, the shopping cart positioning tag 100 is configured with a remote communication unit 106 and a falling-off detection unit 105, and the shopping cart positioning tag 100 can be connected to the server 200 through the remote communication unit 106. The falling-off detection unit 105 can detect whether the shopping cart positioning tag 100 falls off, and when the shopping cart positioning tag 100 falls off from the shopping cart 400, the falling-off detection unit 105 generates a trigger signal. The control unit 104 controls the remote communication unit 106 to send the drop prompt information to the server 200 according to the trigger signal, a management terminal can be configured in a market or a supermarket, the management terminal is connected to the server 200, the drop prompt information is obtained from the server 200, and therefore a manager in the market or the supermarket can conveniently maintain and manage the corresponding shopping cart 400, and the shopping cart 400 placed in the market or the supermarket is guaranteed to have a positioning function.
Alternatively, the drop detection unit 105 may employ any one of a tact switch, a reed switch, a photoelectric sensor, and a pressure sensor, and when the drop detection unit 105 is a tact switch, the tact switch may be abutted against the shopping cart 400, and if the shopping cart positioning tag 100 drops, the tact switch is released, and then a trigger signal is generated. When the fall detection unit 105 is a photoelectric sensor, the photoelectric sensor can be shielded by the shopping cart 400, and if the shopping cart positioning tag 100 falls off, the shopping cart 400 does not shield the photoelectric sensor any more, and light enters the photoelectric sensor, so as to generate a trigger signal. When the fall detection unit 105 is a pressure sensor, the pressure sensor may collide against the shopping cart 400, and if the shopping cart positioning tag 100 falls, the pressure of the pressure sensor is reduced, thereby generating a trigger signal.
For example, referring to fig. 7, the falling-off detection unit 105 may include a single chip microcomputer U500 and a reed switch S2, when the shopping cart positioning tag falls off from the shopping cart, the reed switch S2 is turned off, and no signal is provided to a pin corresponding to the single chip microcomputer U500, so that the single chip microcomputer U500 may control the remote communication unit 106 to send the falling-off prompt information, and may also control the output of an alarm prompt, and thus, the falling-off detection and prompt are implemented.
Referring to fig. 1-2, in some embodiments of the present invention, the shopping cart further comprises an outdoor positioning unit 107, wherein the outdoor positioning unit 107 is connected to the control unit 104 for performing outdoor positioning on the shopping cart 400 to obtain outdoor position information of the shopping cart 400. The remote communication unit 106 is further configured to send the outdoor location information to the server 200 to search the shopping cart 400 pushed out of the house through the server 200.
It is understood that the outdoor positioning unit 107 may employ a beidou positioning module and/or a GPS positioning module. The remote communication unit 106 may be at least one of a cellular mobile communication module, an NB-IoT module, a Lora module, and a halo module.
In actual shopping, as the shopping carts 400 are numerous, most consumers cannot voluntarily push the shopping carts 400 to a designated place after using the shopping carts, and even some consumers push the shopping carts 400 to other outdoor positions outside a shopping mall, so that great troubles are brought to workers managing the carts.
In this embodiment, the outdoor positioning unit 107 can perform outdoor positioning on the shopping cart 400, obtain outdoor location information of the shopping cart 400, and upload the outdoor location information to the server 200 through the remote communication unit 106. A manager of a shopping mall or supermarket can obtain the outdoor location information of the shopping cart 400 from the server 200 through the management terminal, so as to manage the shopping cart 400, for example, can check which shopping carts 400 are located outside the shopping mall or supermarket, and quickly search and retrieve the shopping carts 400 according to the locations of the shopping carts 400.
In an embodiment of the present invention, the UWB positioning module 102 has a sleep mode and an operating mode, and the control unit 104 is further configured to control the UWB positioning module 102 to switch from the sleep mode to the operating mode after the short-range communication unit 103 establishes a short-range communication connection with the user terminal 300, so that the UWB positioning module 102 broadcasts UWB positioning signals under the operation simulation.
Since the shopping cart 400 is generally placed at a predetermined place uniformly when not in use, and since no one uses the shopping cart 400, in this case, if the UWB positioning module 102 is always in a broadcast state, power consumption increases, which leads to a problem that a battery is easily short of power.
In this embodiment, the UWB positioning module 102 is configured with a sleep mode and an operating mode, before the shopping cart positioning tag 100 does not establish close-range communication with the user terminal 300, the UWB positioning module 102 is in a sleep state, in the sleep state, the UWB positioning module 102 does not broadcast UWB positioning signals, or the UWB positioning module 102 broadcasts UWB positioning signals at a longer time interval, so that it can be ensured that the shopping cart positioning tag 100 on the shopping cart 400 is in a low power consumption state when the shopping cart 400 is not in use, thereby reducing the overall power consumption of the shopping cart positioning tag 100, and preventing the problems of easy power shortage of the shopping cart positioning tag 100, short battery life and the like. After the shopping cart positioning tag 100 establishes the short-distance communication with the user terminal 300, it is described that a user is using the shopping cart 400, at this time, the control unit 104 controls the UWB positioning module 102 to switch from the sleep mode to the working mode, and in the working mode, the UWB positioning module 102 broadcasts the UWB positioning signal in real time or at short time intervals, so that it is ensured that the indoor positioning of the shopping cart 400 can be accurately and reliably realized after unlocking.
In other words, the UWB positioning module 102 is controlled to maintain the dormant state when the shopping cart positioning tag 100 is not in close-range communication connection with the user terminal 300, and the shopping cart positioning tag 100 is switched to the working state after being in close-range communication connection with the user terminal 300, so that the power consumption of the shopping cart positioning tag 100 is greatly reduced, the problem of power shortage of the shopping cart positioning tag 100 is prevented to a certain extent, the reliability of the use of the shopping cart positioning tag 100 is improved, meanwhile, the service life of the battery is prolonged, and the maintenance and updating costs are reduced.
Referring to fig. 2, in one embodiment of the present invention, a buzzer 108 is further included, and the buzzer 108 is connected to the control unit 104. The control unit 104 is further configured to control the buzzer 108 to sound an alarm when the position in the outdoor position information exceeds a set electronic fence range.
That is, in this embodiment, the shopping cart positioning tag 100 is configured with a buzzer 108, and the control unit 104 can control the buzzer 108 to sound an alarm when the position in the outdoor position information exceeds the set electronic fence range. Specifically, an electronic fence range is arranged on the server 200, after the shopping cart positioning tag 100 uploads the outdoor position information to the server 200 through the remote communication unit 106, the server 200 can compare the position in the outdoor position information with the electronic fence range, when the position in the outdoor position information exceeds the electronic fence range, the server 200 sends an early warning instruction to the shopping cart positioning tag 100, when the remote communication unit 106 of the shopping cart positioning tag 100 receives the early warning instruction and sends the early warning instruction to the control unit 104, and the control unit 104 can control the buzzer 108 to send out an alarm prompt sound according to the early warning instruction, so that managers and users can conveniently know that the shopping cart 400 exceeds the electronic fence range through the alarm prompt sound.
