The canteen facial recognition consumption machine adopts advanced facial recognition technology for identity verification,which has the advantages of fast recognition speed,high recognition accuracy,non-contact,anti-theft brushing,no loss,advanced technology,good system scalability,and no maintenance investment required.It is a very suitable fee management equipment for the management of internal canteens and school canteens in government agencies,enterprises,and institutions.
The canteen facial recognition consumption machine is equivalent to a conversion of the canteen one card consumption system,which is transformed into canteen one face communication.It can recognize consumption by simply brushing the face.The name"one face communication"corresponds to the well-known"one card",which means replacing the card with a face and confirming identity with the secure identity recognition identifier of the face.Based on this,modern computer technology,network technology,database technology,Internet of Things technology,cloud computing technology,etc.are used to achieve identity recognition,system access,behavior management,electronic consumption and other functions,covering the functions of the"one card",but more convenient and secure than the"one card";Because the cards used in the"One Card"system are prone to loss and may be used fraudulently,while facial recognition does not have these issues.
The facial recognition consumption machine solution for enterprise canteens is divided into two parts.One part is the front-end facial recognition consumption machine,and the other part is the back-end management system.Dining employees only need to stand in front of the consumption machine for one second to"swipe their face"to verify their identity.Real time payment can display employee ID,name,photo,and information such as the current consumption amount and account balance,making it convenient for staff and employees to verify.And the backend can set different subsidy amounts for employees,increasing or decreasing employee information;Recharge,periodic consumption statistics and other functions.
The manifestation of communication failure of canteen vending machine
1、The machine displays"Er-88"during operation
Possible reasons:1.The selected device number does not match the actual device number.2.The selected communication port is faulty or incorrect.3.The communication cable used is incorrect or faulty.4.The serial port is damaged.5.The RS232-CAN converter is damaged.6.The communication distance exceeds the effective distance
Solution:1.Check the machine number on the machine and add it again in the software.2.Check if the connected port number matches the one in the software settings;Replace the device for testing.3.Check the communication cable or replace it.4.Replace the serial port.5.Replace the converter.6.Add matching resistors and repeaters
2、RS232 connection is normal,but CAN connection is invalid
Possible reasons:1.Poor connection wire,reverse connection of CAN communication wire.2.RS232-CAN converter damaged
Solution:1.Check the communication cable or replace it.2.Replace the converter.3.The CAN connection is normal,but RS232 is invalid
