Description
Technical field
The present invention relates to medical care fields, more particularly to can be compatible with equipment, method and the storage of a variety of Wiegand signal mechanism
Medium.
Background technique
With the continuous development of electronic communication, various access control equipments flourish, the technology that access control equipment uses
It is multifarious.Substantial portion of gate inhibition is only controlled by relay, by controlling the switch of relay, to control gate
Opening and closing.But this mode has very big drawback in the equipment for partially having external connection, that is, if someone cuts gate inhibition part
Then the connecting line of relay directly two wiring is connected, then relay is just directly connected, gate is caused to be also turned on.
In this case safety just has no idea ensure that.And the gate inhibition of Wiegand protocol is exactly a kind of mode come into being, Wei
The gate inhibition of root agreement needs to send Wiegand signal from equipment to receiver, and whether receiver is safe by analytical analysis, then controls
Whether open the door.Because being that equipment transmission signal goes to open the door, thus it is not present after cutting line and the case where capable of opening door is connected, this
Sample one carrys out safety and greatly increases.
Existing Wiegand signal read-write equipment is often merely able to meet the Wiegand protocol for exporting some particular number of bits, Zhu Ruchang
26 or 34 Wiegand protocols, but there are many class of Wiegand signal receiver on the market, once client buys
When the Wiegand protocol of other non-common digits, existing Wiegand signal read-write equipment can not then carry out the conversion of data.
So needing to develop the mechanism of a variety of Wiegand protocols of a set of compatibility in equipment, reach a variety of receptions in compatible market
The purpose of device improves product competitiveness.
Summary of the invention
Present invention aims to solve the deficiencies of the prior art, and provides a kind of can be compatible with a variety of Wiegand signal mechanism equipment,
Method and storage medium.
To achieve the goals above, the following technical solution is employed by the present invention:
