[0039] Such as figure 1 As shown, the present invention discloses a protection system for an automatic medicine vending machine, which includes a guide mechanism including a pair of vertical guide rails located on both sides of the operation area of the medicine vending machine.
[0040] A protective door 1 located on the front of the operating area. The protective door 1 is driven by a lifting mechanism along the extending direction of the guide rail or close to the operating area; the lifting mechanism is a wire rope pulley assembly, including a wire rope and a pulley 2. There are two pulleys 2, respectively Parallel and symmetrically arranged on both sides of the top of the protective door 1, there are two sets of wire ropes, one end of which is fixed to both sides of the top of the protective door 1, and the other end is lowered and bypassed the corresponding pulley 2 and then driven by the motor 3 to rise and fall. The motor 3 is fixed at the bottom end of the medicine vend...
Embodiment 2
[0059] In this embodiment, a button for controlling the opening and closing of the infrared sensor 4 is also provided on the infrared sensor 4 in the protection system of the automatic medicine vending machine in embodiment 1. At this time, as image 3 As shown, the control method of the protection system of the automatic medicine vending machine is specifically as follows:
[0060] S201: The control system is powered on and started;
[0061] S202: The controller has a set value of zero to indicate that the button is pressed, and the controller reads the input signal of the button. If the set value of zero is not satisfied, enter S203, if it is satisfied, return to S201;
[0062] S203: The controller has a set value 1 to indicate that the infrared sensor 4 does not detect an active user, the controller reads the input signal of the infrared sensor 4, if the set value 1 is not met, enter S204, if it is satisfied, return to S202;
[0063] S204: The controller has a set value 2 to indica...
