Safety lock system for controlling access to an area in response to predetermined data inputs
First Claim
1. A safety lock system comprising:
- (a) lock means mounted on a gateway to an area for controlling access to the area,(b) a main controller means connected to said lock means for controlling the locking and unlocking of said lock means said main controller means including a comparator means said lock means transmitting to said main controller means a normal operation signal upon completion of said locking or unlocking;
(c) card reader means coupled to said main controller means for reading the data on a card and transmitting said data to said comparator of said main controller means wherein said data is compared to predetermined data; and
(d) display means coupled to said main controller means wherein when said data from said card reader means is in agreement with said predetermined data, said main controller means transmits a locking or unlocking drive signal to said lock means, and when said data from said card reader is not in agreement with said predetermined data, said main controller means transmits a first alarm signal to said display means, and wherein when said main controller means receives a normal operation signal from said lock means, said main controller means transmits a confirmation signal to said display means, and when said main controller means does not receive a normal operation signal from said lock means, said main controller means transmits a second alarm signal to said display means.

Abstract
Herein disclosed is a safety lock system which includes an electric lock mounted on a gateway to a certain region, a card reader, a display device and a main controller. The main controller is arranged so that it can check the card data read by the card reader. Accordingly, when the card data are in agreement with the predetermined data, the main controller feeds a locking or unlocking drive signal to the electric lock. On the contrary, when the card data are not in agreement with the predetermined data, the main controller emits a first alarm signal to the display device. Furthermore, when the main controller receives a normal operation signal from the electric lock, the main controller emits a signal of confirmation of the normal operation of the electric lock to the display device; whereas when the main controller does not receive the normal operation signal, it emits a second alarm signal to the display device.
