Device and method capable of being compatible with multiple Wiegand signal mechanisms and storage medium

Abstract

The invention relates to a device and method capable of being compatible with multiple Wiegand signal mechanisms and a storage medium. According to the present invention, a first interface and a second interface are developed on the basis that the protocols of most receivers on the market are 26-bit protocols and 34-bit protocols, and the two interfaces can meet the use requirements of most customers; if a client has a special receiver needing to be matched, the invention also provides another two custom interfaces, namely a third interface and a fourth interface. The third interface is used for analyzing the second processing user data and converting the second processing user data into the Wiegand protocol data with digits corresponding to the Wiegand signal receiver, and the fourth interface comprises an external D0 hardware interface and an external D1 hardware interface and is used for analyzing the first processing user data and converting the first processing user data into the Wiegand protocol data with digits corresponding to the root signal receiver. The diversity of equipment adaptation is increased through the interfaces, and the interfaces are suitable for most customers, so that different diversified customization requirements are greatly met.

Description

technical field [0001] The invention relates to the field of medical care, in particular to equipment, methods and storage media compatible with various Wiegand signal mechanisms. Background technique [0002] With the continuous development of electronic communication technology, all kinds of access control equipment are flourishing, and the technologies used by access control equipment are also varied. A large part of access control is only controlled by relays, and the opening and closing of the gate is controlled by controlling the switch of the relay. However, this method has a great disadvantage in some devices with external wiring, that is, if someone cuts off the connecting wire of the relay in the access control part, and then directly connects the two wires, then the relay will be directly connected, causing the door to be blocked. Open. There is no way to guarantee the security in this case. The access control of the Wiegand protocol is a way that came into bei...

AI Technical Summary

Problems solved by technology

[0003] Existing Wiegand signal read-write devices are often only capable of outputting some Wiegand protocols with specific digits, such as the commonly used 26-bit or 34-bit Wiegand protocols, but there are many types of Wiegand signal receivers on the market. When customers purchase other Wiegand protocols with unused bits, the existing Wiegand signal reading and writing equipment cannot perform data conversion
