[0035] Further, the working principle of the second seat belt plug 8 and the second seat belt connector 9 on the second seat of the first row is the same, and since the first seat belt connector 6 and the second seat belt connector 9 are close in position, the first seat belt plug 5 may be installed inside the second seat belt connector 9, and the second seat belt plug 8 may be installed inside the first seat belt connector 6, causing the seat belts to be entangled with each other. When the first NFC coil detects the second NFC coil that does not match it, the alarm will sound to remind the passenger that the seat belt is not connected correctly, thereby ensuring that the passenger fastens the seat belt and reducing the possibility of the seat belts being entangled with each other. The NFC coil model is "‌NTAG213 label".

[0036] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in a preferred embodiment, one end of the power connector 15 is provided with a network cable 16 near the position of the multifunctional line 14. The network cable 16 is connected to a cloud database, which is used to determine the connection state of the first seat belt plug 5 and the first seat belt connector 6 and the second seat belt plug 8 and the second seat belt connector 9.

[0037] Specifically, the upper surface of the controller 1 is provided with a number tube 17, and the upper surface of the controller 1 is provided with two keys 18 near the position of the number tube 17.

[0038] In this embodiment, when the bus needs to be installed with more first seat belt plugs 5, first seat belt connectors 6, second seat belt plugs 8 and second seat belt connectors 9 on more seats, more interfaces are expanded through the expansion port 19 to install more first seat belt plugs 5, first seat belt connectors 6, second seat belt plugs 8 and second seat belt connectors 9. The multifunctional line 14 can also power the controller 1 while transmitting information. The controller 1 sends the connection state of the first seat belt plug 5, the first seat belt connector 6, the second seat belt plug 8 and the second seat belt connector 9 to the cloud database through the multifunctional line 14, the network cable 16 and the wireless network on the vehicle, and numbers the seats on the bus. The number tube 17 is used to display the serial number of the seat on the bus where the seat belt is not fastened correctly.

[0039] Working principle: when in use, the display screen 12 is installed in the cab of the bus, the seats of the bus are side by side, the first safety belt connecting end 6 is installed at the position of connecting the safety belt of the first seat in the first row, the first safety belt plug 5 is connected with the safety belt of the first seat in the first row, the first mounting piece 4 is installed at the bottom of the first seat in the first row, the second safety belt plug 8 is installed at the position of connecting the safety belt of the second seat in the first row, the second safety belt connecting end 9 is connected with the safety belt of the second seat in the first row, the second mounting piece 7 is installed at the bottom of the second seat in the first row, and the power connector 15 is connected with the power supply on the bus. When the passenger gets on the bus and sits on the first seat in the first row, the first mounting piece 4 detects that the passenger sits down, and the first NFC coil inside the first safety belt connecting end 6 is powered on. When the second NFC coil inside the first safety belt plug 5 is detected, the display screen 12 displays that the safety belt of the first seat in the first row has been connected, otherwise it displays that the safety belt is not connected. The alarm inside the first mounting piece 4 sends an alarm to remind the passenger to fasten the safety belt. Similarly, the working principle of the second safety belt plug 8 and the second safety belt connecting end 9 on the second seat in the first row is the same. Since the first safety belt connecting end 6 and the second safety belt connecting end 9 are close in position, the first safety belt plug 5 may be installed inside the second safety belt connecting end 9, and the second safety belt plug 8 may be installed inside the first safety belt connecting end 6, which may cause the safety belts to be entangled with each other. When the first NFC coil detects the second NFC coil that does not match it, the alarm will sound to remind the passenger that the safety belt connection is incorrect, which can ensure that the passenger fastens the safety belt and reduce the possibility of entanglement of the safety belts. When the bus needs to install more first safety belt plugs 5, first safety belt connecting ends 6, second safety belt plugs 8 and second safety belt connecting ends 9 on more seats, more interfaces can be expanded through the expansion port 19 to install more first safety belt plugs 5, first safety belt connecting ends 6, second safety belt plugs 8 and second safety belt connecting ends 9. The multifunctional line 14 can also power the controller 1 while transmitting information. The controller 1 sends the connection status of the first safety belt plug 5, the first safety belt connecting end 6, the second safety belt plug 8 and the second safety belt connecting end 9 to the cloud database through the multifunctional line 14, the network cable 16 and the wireless network on the vehicle, and gives the seat number on the bus. The nixie tube 17 is used to display the serial number of the seat on the bus where the safety belt is not fastened correctly.
