Problems solved by technology
The disadvantages of this traditional medicine storage cabinet are: one, the control part of the existing medicine delivery system completely depends on the logic program of the control circuit itself, which has low reliability and poor efficiency; There are a large number of tanks, and the boxed medicines stored in each medicine storage tank are different. Therefore, when it is necessary to replenish medicines in the medicine storage cabinet, it takes a lot of time to find the corresponding medicine storage tank for each medicine replenishment. extremely inconvenient
To sum up, the existing automatic medicine vending machines have the problems of low reliability, poor efficiency, inconvenient and error-prone maintenance personnel.
