Specific implementation manners
[0033] The technical solutions in the present application will be further described in detail below with reference to the accompanying drawings.
[0034] The present application discloses a campus personnel information collection system. Please refer to Figure 1 , in some examples, the campus personnel information collection system disclosed in the present application includes an identity card 1 and a wireless terminal 2. The identity card 1 is carried by a person, and the wireless terminal 2 is installed on campus. The installation location is determined according to the coverage area of the wireless terminal 2 to ensure full coverage on campus. The dotted line indicates the coverage range of the wireless terminal 2.
[0035] Please refer to Figure 2 , the identity card 1 includes a card body 11, a cavity 12 provided in the card body 11, a power source 13 provided in the cavity 12, and a communication circuit 14 provided in the cavity 12 and electrically connected to the power source 13. The power source 13 supplies power to the communication circuit 14.
[0036] Please refer to Figure 3 , the communication circuit 14 includes a microcontroller 141, a wireless transceiver chip 142, and a power management chip 143. Both the wireless transceiver chip 142 and the power management chip 143 are electrically connected to the microcontroller 141. The wireless transceiver chip 142 is responsible for sending identity signals and receiving instruction signals. The power management chip 143 is electrically connected to the power source 13 and is responsible for supplying power to the microcontroller 141 and the wireless transceiver chip 142.
[0037] Sending an identity signal means sending a digital code stored in the wireless transceiver chip 142. Each person has a unique digital code; receiving an instruction signal means receiving an instruction sent by the wireless terminal 2.
[0038] This involves the acquisition method of location information. There are two location information acquisition methods in the present application. The first is that the wireless transceiver chip 142 sends an identity signal (digital code) at a set frequency, for example, once every half hour or once every hour.
[0039] The second is that the wireless transceiver chip 142 sends an identity signal (digital code) after receiving an instruction signal sent by the wireless terminal 2. This method is at random time.
[0040] In some examples, the power supply 13 is a rechargeable battery, and a charging induction circuit 15 is added to the identity card 1. As Figure 4 shown, the charging induction circuit 15 is electrically connected to the power management chip 143 to implement wireless charging.
[0041] In some examples, please refer to Figure 5 , the power supply 13 includes a base 131 and a battery 132 detachably connected to the base 131. At the same time, a through hole 111 and a cover plate 112 are added to the card body 11. The through hole 111 communicates with the cavity 12, and the cover plate 112 is detachably connected to the card body 11 to close the through hole 111. The battery 132 is located below the cover plate 112.
[0042] The battery 132 at this time can use a button battery.
[0043] In some examples, please refer to Figure 2 , a shielding ring 16 is added to the cavity 12. The power supply 13 or the communication circuit 14 is located within the shielding ring 16. The function of the shielding ring 16 is isolation, so that the power supply 13 and the communication circuit 14 do not interfere with each other.
[0044] In some examples, the shielding ring 16 is only located on the side surface of the cavity 12.
[0045] In some examples, please refer to Figure 6 , a slot 113 is provided on the surface of the identity card 1. The function of the slot 113 is to place the identity card. After replacing the identity card, the identity card 1 provided by this application can be used by a new person.
[0046] It should be additionally noted that for the microcontroller 141, a low-power chip needs to be used, such as STM32L0 and STM32U0. The wireless transceiver chip 142 uses a CMT2119A transmitter and a CMT2219A receiver, and the power management chip uses an ETA4098 power management IC.
[0047] For the wireless terminal 2, the core components are also a processor, a signal transmitter and a signal receiver. Compared with the microcontroller 141 and the wireless transceiver chip 142, the difference is that it needs to have a higher processing speed and greater power. For example, the processor can select MT7620A, and the signal transmitter and signal receiver can select ESP32. ESP32 integrates signal transceiver functions.
[0048] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
