when the unlock state signal is unlock, the first in-place signal is out of place and the second in-place signal is out of place, the switch operating handle storage state is determined to be timeout.
In the present embodiment, the preset pressure threshold is specifically understood to be a pressure value preset according to the weight of the switch operation handle in the handle storage module 20, and the switch operation handle in the handle storage module 20 may be considered to exist when the preset pressure threshold is exceeded. Alternatively, the infrared sensor 22 in the embodiment of the present invention may be an infrared correlation sensor, which includes a transmitting end 221 for transmitting infrared rays and a receiving end 222 for receiving the infrared rays transmitted from the transmitting end 221.

The unlock control signal is specifically understood as a control signal transmitted to the handle storage module 20, the pressure sensor 21, and the infrared sensor 22 when it is judged that the switch operation handle is available, to control each module to perform necessary operations for the switch operation handle to be taken. The locking control signal is specifically understood as a control signal sent to the handle storage module 20, the pressure sensor 21 and the infrared sensor 22 when it is determined that the switch operation handle is returned or not available, so as to control the handle storage module 20 to fix the switch operation handle, and control the pressure sensor 21 and the infrared sensor 22 to monitor the in-place condition of the switch operation handle. The first preset time can be specifically understood as a time that the determined general switch operation handle needs to be taken after counting each time of use time in the switch operation handle history, and if the time is exceeded, the switch operation handle can be considered to be lost or misplaced.

Specifically, the near field communication module 23 may determine, by acquiring the number of times of the same personnel identity card information, that the personnel performs a specific operation on the switch operation handle, for example, if the number of times of the personnel identity card information being acquired is singular, the personnel may be considered to be currently operating as a taking operation; if the number of times the staff identity card information is acquired is a double number, the staff can be considered to be currently operated as returning operation. Upon determining that the switch operation handle is taken, the near field communication module 23 determines the unlock state signal as unlock, and simultaneously generates and transmits an unlock control signal to the handle storage module 20, the pressure sensor 21, and the infrared sensor 22, respectively. The handle storage module 20 may control the electronic lock 203 provided therein to be unlocked upon receiving the unlocking control signal so that the switch operation handle stored in the handle storage module 20 may be taken out. The pressure sensor 21 temporarily stops acquiring the pressure value of the bearing portion 201 when receiving the unlock control signal, that is, stops acquiring the first in-place signal, and at the same time, after a first preset time, can consider that the switch operation handle should be returned, at which time the acquisition of the first in-place signal is resumed. The infrared sensor 22 temporarily stops the infrared receiving of the infrared transmitting and receiving end 222 of the transmitting end 221 when receiving the unlocking control signal, that is, stops collecting the second in-place signal, and at the same time, after the first preset time, can consider that the switch operation handle should be returned, and at this time, the collection of the second in-place signal is resumed, so that the data collection communication module 24 can continuously determine the storage state of the switch operation handle according to the obtained first in-place signal, the second in-place signal and the unlocking state signal.
Specifically, upon determining that the switch operation handle is returned, the near field communication module 23 switches the unlock state signal from unlock to lock, and simultaneously generates and transmits a lock control signal to the handle storage module 20, the pressure sensor 21, and the infrared sensor 22, respectively. The handle storage module 20 can control the electronic lock 203 provided therein to be locked when receiving the locking control signal, so that the switch operation handle returned to be placed in the handle storage module 20 is locked and cannot be taken out at will. The pressure sensor 21 resumes the acquisition of the first presence signal, i.e. the determination of the presence state of the switch operating handle stored in the handle storage module 20, upon receipt of the blocking control signal, without waiting for the arrival of the first preset time. The infrared sensor 22 resumes the infrared receiving function of the infrared transmitting and receiving end 222 of the transmitting end 221 upon receiving the blocking control signal, that is, resumes the acquisition of the second in-place signal without waiting for the arrival of the first preset time.
Specifically, the data acquisition communication module 24 acquires the first in-place signal, the second in-place signal, and the unlock state signal in real time to determine the storage state of the switch operating handle. When the obtained unlock state signal is a lock, the switch operation handle is considered to be normally stored in the handle storage module 20, and if the first in-place signal and the second in-place signal are in place, the switch operation handle stored in the handle storage module 20 is considered to be a complete normal switch operation handle, and the switch operation handle storage state is determined to be in place; if one of the first and second presence signals is not present, it is considered that the stored switch operation handle is damaged or the stored object is not matched, and the stored switch operation handle is determined to be abnormal. When the obtained unlocking state signal is unlocking, the switch operation handle can be considered to be taken, whether the switch operation handle is taken or not can be determined according to the obtaining conditions of the first in-place signal and the second in-place signal, if the first in-place signal and the second in-place signal are not received, the pressure sensor 21 and the infrared sensor 22 can be considered to be in a first preset time after the unlocking control signal is received, namely, the switch operation handle can be considered to be in a normal taken state, and at the moment, the storage state of the switch operation handle is determined to be taken; if the first presence signal and the second presence signal are both not present, it may be considered that the pressure sensor 21 and the infrared sensor 22 have restarted to acquire the first presence signal and the second presence signal, and the taking time of the switch operation handle has exceeded the first preset time, that is, the time required for taking the switch operation handle after the switch operation handle is taken out by the staff is considered to be longer than the normal time, and there is a possibility of losing or erroneously storing the switch operation handle, and at this time, the storage state of the switch operation handle is determined to be overtime.
