Background

In the existing mechanisms such as supermarkets, after a cashier checks the cash, customers leave the supermarkets with paid commodities through an outlet at the side of a cashier desk in a general mode. In actual operation, especially in supermarkets with large flow of people and many customers, because a large number of customers are concentrated at the cash register, the flow of people in the supermarket is large through the cash register, and sometimes some customers can not enter the supermarket from the side of the cash register which is not used as an entrance, the flow of people is increased, so that more pressure is brought to the work of cash registers, and even the cash registers can not charge some customers for shopping because of being too busy, and economic loss is brought to the supermarket. In order to prevent customers from entering the supermarket through the outer side of the side end opening of the cash register table, special management personnel are generally arranged at the side end opening of the cash register table to dredge the personnel entering the supermarket and indicate correct passages for the customers entering the supermarket, so that the phenomenon that the customers enter the supermarket through the outlet of the cash register table is reduced, and meanwhile, the burden of the cash register personnel is reduced. However, in the above management mode, a professional is required for management, so that the labor cost is increased for a supermarket operator, and when the amount of people is large, the number of management personnel is small, or the management is not in place, the probability that a customer enters the supermarket through the outlet of the checkout counter is also high.

The entrance guard equipment is an automatic control device which is widely applied and can realize the passing or blocking of people in an area needing to be isolated. For example, the existing entrance guard equipment widely used in the residential area has the main structure including a track rod device driven by a motor deceleration driving mechanism, a support frame for supporting the track rod, a control system and the like. However, if the existing access control equipment is directly applied to a large supermarket or the like as an entrance/exit passage at the side end of a cash register, as the customer needs to swipe a card or a manager and the customer presses a power switch when entering or exiting, because each customer cannot be provided with an IC entrance/exit card, each customer cannot be familiar with an operation mode for controlling the power switch, and the arrangement of a special manager also has the defect of increasing the labor cost of a supermarket operator, which is obviously not suitable; and the existing entrance guard equipment is bidirectional in traffic, and if the existing entrance guard equipment is applied to the control of the side end channel of the cash register of the supermarket, the existing entrance guard equipment cannot effectively prevent a customer from entering the supermarket through the cash register channel, so that the existing entrance guard equipment also has no use value.
