[0051] In combination with Figure 4 , Figure 5 and Figure 10 It is shown that Figure 10To show the circuit diagram of the prompting component 200, the pins PB4, PB5 and PB6 on the single-chip microcomputer 410 are connected with the prompting component 200, Figure 5 To show the circuit diagram of the light sensor 300, the pin PA0 on the single-chip microcomputer 410 is connected with the light sensor 300, that is, the pins PB4, PB5, PB6, PA0 and the internal circuit of the single-chip microcomputer 410 constitute the transmission end detection unit in this embodiment.

[0052] Specifically, in combination with Figure 4 and Figure 5 and Figure 10 As shown in the figure, the light sensor 300 includes a detection member 310 and a comparator 320, the output end of the detection member 310 is connected with the IN- end of the comparator 320, the IN+ end of the comparator 320 inputs a 3V voltage, the comparator 320 compares the voltage input by the detection member 310 with the 3V voltage, and outputs a high level or a low level at the VOUT end based on the comparison result, the level output at the VOUT end is transmitted to the single-chip microcomputer 410 through the PA0, and the single-chip microcomputer 410 outputs an indication state switching signal through the pins PB4, PB5 and PB6 to trigger the prompting component 200 based on the high or low level received at the PA0.

[0053] In other embodiments, the single-chip microcomputer 410 of the main control circuit board 400 can also be replaced by a DSP (digital signal processor), an FPAG (field programmable gate array) and the like, and the I / O pins corresponding to the data transmission unit or the transmission end detection unit can be selected based on actual needs.

[0054] In this embodiment, the indication state switching signal can be one of the high level signal and the low level signal output by the transmission end detection unit.

[0055] In this embodiment, the working frequency band of the shielding box 100 for isolating or shielding electromagnetic waves is 2G~7.5GHz, and the isolation degree is greater than or equal to 50db; in other embodiments, the working frequency band or the isolation degree of the shielding box 100 can be adjusted based on actual shielding needs.

[0062] In this embodiment, the actual current within the preset current interval indicates that the connection between the data transmission unit, the data delivery device 910 and the data receiving device 920 is stable, and the data can be transmitted; the actual current exceeding the preset current interval indicates that the connection between the data transmission unit, the data delivery device 910 and the data receiving device 920 is invalid, resulting in that the data cannot be transmitted or the data transmission is incorrect. The current monitoring unit outputs the fourth trigger signal when the actual current is within the preset current interval, so as to trigger the prompting component 200 to send the prompt information, prompting the user that the data delivery device 910 and the data receiving device 920 can perform stable data transmission.

[0063] In this embodiment, the third trigger signal can be one of the high-level signal and the low-level signal output by the current monitoring unit, and the corresponding fourth trigger signal is the other one.
