Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example 1
This embodiment discloses an intelligence attendance positioning terminal based on UWB, its characterized in that includes: communication module 1, UWB module 2, orientation module 3, power module 4, wherein:
and the communication module 1 is used for receiving the user positioning information and the attendance information and uploading the positioning information and the attendance information to the management platform.
Specifically, communication module 1 carries out data transmission, reports positioning information to management platform, and communication module 1 can be mobile cellular network modules such as 5G, 4G, NB, 2G, also can be local communication module 1 such as Wi-Fi that indoor use, BLE, loRa.
A UWB module 2, when a UWB base station is near the terminal, the UWB module is used to obtain the user positioning information; the system is also used for receiving an attendance instruction and acquiring user attendance information; and the positioning information and the attendance information are uploaded to a management platform through the communication module 1.
Specifically, UWB is also called impulse radio technology, which directly communicates with baseband pulses having steep rising and falling edges, unlike carrier modulation technology widely used in communication systems of today, and is therefore also called baseband transmission (baseband) or carrier-less (carrier) technology. Pulsed UWB typically has pulse lengths on the order of sub-nanoseconds, with signal bandwidths often reaching many gigahertz, much greater than the bandwidth of any existing wireless communication technology. Early Ultra Wideband (UWB) technology was used for short-range transmission of large data, and has been used in wireless positioning applications in recent years. The UWB positioning technology belongs to one of wireless positioning technology. Wireless location technology refers to measurement and calculation methods, i.e., location algorithms, used to determine the location of a mobile user. In this embodiment, the method for the UWB module 2 to obtain the user positioning information includes: the data are transmitted by nanosecond-level non-sine wave narrow pulses, and accurate positioning and direction identification are carried out through the arrival angle, arrival time difference and received signal strength of the data arriving at a base station.
In this embodiment, the priority of use of the UWB module 2 is higher than that of the positioning module 3, and when there is a UWB base station, the UWB module 2 is used to acquire user positioning information; when no UWB base station exists, the positioning module 3 is started to acquire the user positioning information. In terms of power consumption, the GPS consumes the most power, and the UWB saves the most power, so that the power consumption of the terminal can be reduced, and the endurance of the terminal can be improved.
In this embodiment, the method for the UWB module 2 to receive the attendance instruction and acquire the user attendance information includes:
binding the list of the personnel to be checked with the unique identification code of the terminal respectively;
the administrator selects a list of the people to be checked through the checking-in APP;
the APP issues the attendance instructions to the terminals of the personnel to be checked through the management platform;
starting the UWB module 2 of the terminal of the person to be checked, searching the terminals of the peripheral UWB module 2, and recording the terminal and the searched terminal numbers;
the terminal of the person to be checked sends the number of the person to be checked and the searched number to the management platform;
and the management platform matches the uploaded number information with the list information of the staff to be checked to acquire the attendance information of the user.
It should be noted that, the UWB module 2 can complete thousands of scans within 1 second based on nanosecond-level transmission frequency, and therefore, all device numbers can be scanned within a distance range. If some terminal should miss, other terminals can also complete the number scanning. And finally, uploading UWB numbers scanned by all the terminals, and taking the union set by the management platform to obtain the equipment for actual attendance checking.
Furthermore, if some terminals do not scan other UWB terminals and only upload their ID numbers, it is indicated that these terminals are not close to any other terminals, that is, are not within range, and are absent attendance.
Furthermore, if one group of terminals can only scan the UWB terminals with the respective fixed numbers and cannot scan the UWB numbers of the other group of terminals, the attendance checking personnel are divided into a plurality of areas. The administrator can check whether the attendance of all the persons is normal or whether a part of the persons is abnormal according to actual conditions. Specifically, for example: students take school buses to go to school, N school buses can form at most N independent areas, and an administrator can judge whether any student goes to school buses and is absent from duty, but equipment among the school buses can not complete mutual scanning.
In some preferred embodiments, the terminal can also implement the zone attendance function, for example, the a terminal can be connected to the B terminal, the C terminal can be connected to the B terminal, and the B terminal is connected to the D terminal, so that A, B, C, D terminals are all within a UWB transmission range, implementing the zone attendance function.
And the positioning module 3 is opened when no UWB base station is arranged near the terminal, and is used for assisting in acquiring the positioning information of the user and uploading the positioning information and the attendance information to the management platform through the communication module 1.
In some preferred embodiments, the positioning module 3 is a GPS \ GNSS module or \ and WIFI probe module. When the terminal has a UWB base station position, the positioning module 3 does not need to be started, when the UWB module 2 cannot search the UWB base station, the positioning module 3 is started, and when the terminal is outdoors, the positioning module 3 can be a GPS \ GNSS module, and positioning is performed through the GPS \ GNSS module to acquire user position information. When the user arrives and has the wifi environment, orientation module 3 can be for the wifi probe, realizes the location through the wifi probe, acquires user position information.
And the power supply module 4 is used for supplying power to the terminal and ensuring the continuous endurance of the terminal.
In some preferred embodiments, the terminal further comprises: a voice module; the voice module is used for providing voice and conversation capacity between the terminal and the management platform. The voice module can be a microphone/loudspeaker module, and can provide voice and conversation capability when based on a cellular network such as 5G/4G/2G.
In some preferred embodiments, the terminal further comprises: an SE module; the SE module is used for providing hardware encryption and decryption capacity, providing safety guarantee for transmission of the terminal, and meanwhile, the financial application can be stored, so that NFC related payment is facilitated.
In some preferred embodiments, the terminal further comprises an MCU module; the MCU module is used for managing other modules of the terminal and also used for hanging other modules which the terminal does not have to hang down to expand the functions of the terminal.
