one or more opposite photoelectric protection devices are arranged along the length direction of two sides of the lower surface of a vehicle carrier plate of the stereo garage, and a plurality of reflection-type photoelectric protection devices are arranged around the side surface and/or the lower surface edge of the vehicle carrier plate, wherein the detection area of the opposite photoelectric protection device is a first detection area, the opposite photoelectric protection device is used for converting a first optical signal in the first detection area into a first electric signal, the detection area of the reflection-type photoelectric protection device is a second detection area, and the reflection-type photoelectric protection device is used for converting a second optical signal in the second detection area into a second electric signal;
and receiving and judging a first electric signal output by the correlation type photoelectric protection device and a second electric signal output by the reflection type photoelectric protection device, and controlling and cutting off a power supply circuit of the lifting device according to a judgment result to prohibit the lifting action of the vehicle carrier plate, wherein the judgment result corresponds to the first detection area and the second detection area and is respectively the existence of a shielding object or the absence of the shielding object.
8. The security monitoring method of claim 7, further comprising:
if the level value of the first electric signal is 1, judging that a shielding object exists in the first detection area, and controlling to cut off a power supply circuit of the lifting device by the control module;
and if the level value of the second electric signal is 1, judging that a shielding object exists in the second detection area, and controlling to cut off a power supply circuit of the lifting device by the control module.
9. The security monitoring method of claim 7, further comprising:
and if the level value of the first electric signal and the level value of the second electric signal are both 0, judging that no shielding object exists in the first detection area and the second detection area, and controlling and conducting a power supply circuit of the lifting device by the control module.
10. The security monitoring method of claim 7, wherein the stereo garage further comprises a prompting device, the security monitoring method further comprising:
and if the judgment result shows that the shielding object exists in any one of the first detection area and the second detection area, controlling the prompting device to send out a safety prompting signal.
