So set up, can carry out different configurations to controlling means 300 to different automatic vending machine 010, the first signal of the different frequencies that first optical generator 310 that makes different automatic vending machine 010 receive controlling means 300 and send, and first signal according to different frequencies is luminous with different frequencies, lawless persons are difficult to forge the situation that optical generator simulates cabinet door 200 and seals the opening 110 of cabinet body 100 to different automatic vending machine 010, further improve the lawless persons and simulate the degree of difficulty of the opening 110 that cabinet door 200 seals the cabinet body 100 through forging optical generator promptly, further improve automatic vending machine 010's security.

Referring to fig. 2, the vending machine 010 of the embodiment further includes a second light generator 330 and a second light receiver 340, one of the second light generator 330 and the second light receiver 340 is disposed in the cabinet 100, and the other is disposed in the cabinet door 200; when the cabinet door 200 closes the opening 110 of the cabinet 100, the second light generator 330 is opposite to the second light receiver 340, and the second light receiver 340 can receive light emitted by the second light generator 330; when the cabinet door 200 opens the opening 110 of the cabinet body 100, the second light generator 330 and the second light receiver 340 are separated, and the second light receiver 340 cannot receive light emitted by the second light generator 330; the second light generator 330 and the second light receiver 340 are both in communication connection with the control device 300, and the control device 300 is further specifically configured to: sending a third signal to the second light generator 330; acquiring a fourth signal output by the second optical receiver 340, and judging whether the fourth signal is matched with the third signal; if the fourth signal does not match the third signal, it is determined that the cabinet door 200 opens the opening 110 of the cabinet 100.

In the case that the vending machine 010 is provided with the first light generator 310, the first light receiver 320, the second light generator 330 and the second light receiver 340 at the same time, the control device 300 determines that the cabinet door 200 closes the opening 110 of the cabinet 100 only when it is determined that the second signal matches the first signal and the fourth signal matches the third signal; if the second signal is not matched with the first signal, or the fourth signal is not matched with the third signal, or the second signal is not matched with the first signal, and the fourth signal is not matched with the third signal, the control device 300 determines that the cabinet door 200 opens the opening 110 of the cabinet body 100; thus, the difficulty of a lawbreaker who simulates the cabinet door 200 to close the opening 110 of the cabinet body 100 by counterfeiting the light generator can be further improved, and the safety of the vending machine 010 can be further improved.

In this embodiment, the second light generator 330 is disposed on the cabinet door 200, and the second light receiver 340 is disposed on the cabinet 100; in other embodiments, the second light generator 330 is disposed in the cabinet 100, and the second light receiver 340 is disposed in the cabinet door 200.

Further, the third signal is a pulse signal, and the control device 300 sends the third signal to the second light generator 330 through the pulse width modulation output.

Still further, the control device 300 is specifically further configured to: the frequency of the third signal is calculated from the received parameters and a corresponding third signal is sent to the second light generator 330 based on the calculated frequency. So set up, can further carry out different configurations to controlling means 300 to different automatic vending machine 010, the third signal of the different frequencies that makes different automatic vending machine 010's second light generator 330 receive controlling means 300 send to it is luminous with different frequencies according to the third signal of different frequencies, further improve lawless persons through the degree of difficulty of forging light generator simulation cabinet door 200 and sealing the opening 110 of cabinet body 100, further improve automatic vending machine 010's security.

In other embodiments, the frequencies of the first and third signals sent by the control device 300 to the first and second

light generators

310, 330 may be the same, such that the first and second

light receivers

320, 340 output the second and fourth signals at the same frequency; in this way, the setup of the control device 300 can be simplified.

It should be noted that in other embodiments, only the first light generator 310 and the first light receiver 320 may be provided in cooperation with each other, and the second light receiver 340 and the second light generator 330 may not be provided.

The vending machine 010 of this embodiment determines whether the cabinet door 200 closes the opening 110 of the cabinet 100 by comparing whether the first signal received by the first light generator 310 matches the second signal output by the first light receiver 320, and comparing whether the third signal received by the second light generator 330 matches the fourth signal output by the second light receiver 340; when the first signal matches with the second signal and the third signal matches with the fourth signal, the control device 300 determines that the cabinet door 200 closes the opening 110 of the cabinet 100. Thus, the difficulty of a lawbreaker who simulates the cabinet door 200 to close the opening 110 of the cabinet body 100 by counterfeiting the light generator can be further improved, and the safety of the vending machine 010 can be further improved.
