In some embodiments, as shown in FIG. 1, the control system 100 further includes an electronic device 20, 30, which may be a smart phone (such as the electronic device 20), a tablet, or a smart bracelet (such as the electronic device 30). Or other devices that can be set to emit light, for convenience of description, the electronic device 20 will be described as an example below.

In an embodiment, referring to FIG. 2, the electronic device 20 includes a processor 21, a modulation circuit 23, a light source driving circuit 25, and a light emitting unit 27. The processor 21 is used to perform various operations, and is implemented by integrated circuits such as a micro control unit, a microprocessor, a digital signal processor, a special application integrated circuit or a logic circuit. In one embodiment, the light-emitting unit 27 may be implemented by a light-emitting diode (LED), or may be implemented by a fill light, a charging indicator, a screen, or other light-emitting devices of the electronic device 20.

It should be noted that the information of Table 1 is stored in a storage device of the electronic device 20 (such as a memory, a hard disk, a flash memory card). Similarly, the information of Table 1 is also stored in a storage device of the elevator system 10 Medium (such as memory, hard drive, flash drive memory card).

For example, when the floor information is the second floor, the modulation circuit 23 searches the corresponding flashing pattern code (ie, "101010") contained in Table 1 and transmits the flashing pattern code to the light source driving circuit 25 .

Then, the light source driving circuit 25 causes the light emitting unit 27 to emit a light source signal LIT according to the blinking pattern code.

In one embodiment, the elevator system 10 further includes an amplifier circuit 15 for amplifying the light source signal LIT received by the photodetector 17 and transmitting the amplified light source signal LIT to the demodulation circuit 13.

In step 340, the demodulation circuit 13 demodulates a blinking pattern code corresponding to the light source signal LIT, and obtains floor information according to the blinking pattern code.

For example, when the light source signal LIT received by the light detector 17 is "bright dark bright dark bright dark", the demodulation circuit 13 turns on the light-emitting unit 27 (bright) according to 1 in the flicker pattern code, and 0 means turn off the light The rule of unit 27 (dark) is to demodulate the flickering pattern code corresponding to the light source signal LIT as "101010", and search Table 1 (which is a record of floor information and Correspondence table of the flashing style code), use Table 1 to query and obtain the floor information corresponding to the flashing style code "101010" as the second floor.

Thereby, the elevator system 10 can know the floor which the user UR1 wants to reach.

In step 350, the processor 11 of the elevator system 10 controls the movement of the elevator according to the floor information. For example, the processor 11 controls the elevator to move to the second floor according to the floor information.

In addition, in some embodiments, the elevator control system on the market can be applied in this case, and the photodetector 17 and the demodulation circuit 13 are connected to the original elevator control system (already equipped with the processor 11).
