Abstract
An elevator security system for a building includes data relating to a floor that a user may access in the building, a device in which the data is stored, a credential containing the data in a machine readable format and created by the user, and a first machine reader reading the credential and sending data therein to the device for querying whether the user may access the floor, the device allowing access to an elevator car for transport to the floor if the credential is in sync with the data stored in the device.
Claims23
An elevator security system for a building comprising:
- data relating to a floor that a user may access in said building,
- a device storing said data,
- a credential transmitted electronically to said user, said credential allowing said user to place said credential in a machine readable format and use said data to access said floor, and
- a first machine reader reading said credential in the machine readable format for querying said device whether said user may access said floor, said device providing access to an elevator car for transport to said floor if said credential is in agreement with said data stored in said device,
- wherein said user is a first distance from the first machine reader when the credential is transmitted to the user, and the user is a second distance from the first machine reader when the first machine reader reads the credential, the second distance being less than the first distance.
An elevator security method comprising the steps of:
- sending a credential electronically to a user of a building when said user is a first distance from a credential reader,
- sending data as to a first floor that said user may utilize in said building to a device for said building,
- placing said credential in a machine readable format remotely from said building,
- automatically reading said machine readable format with a credential reader at said building when the user is a second distance from the credential reader, the second distance being less than the first distance, and
- submitting the read machine readable format to said device that assigns an elevator car to deliver said user to said first floor if said read machine readable format is in agreement with said data.
An elevator system comprising:
- data relating to a floor that a user may access in said building,
- a device storing said data,
- a credential transmitted electronically to said user, said credential allowing said user to place said credential in a machine readable format and use said data to access said floor, and
- a first machine reader reading said credential in the machine readable format for querying said device whether said user may access said floor, said device assigning an elevator car for transport to said floor if said credential is in agreement with said data stored in said device,
- wherein said user is a first distance from the first machine reader when the credential is transmitted to the user, and the user is a second distance from the first machine reader when the first machine reader reads the credential, the second distance being less than the first distance.
