Abstract
An electronic locking system in which the control computer and a plurality of locking devices are connected by a data bus, and in which the communication between the external computers and each locking device is carried out by element of commands sent through the data bus.
Claims14
A locking system including more than one locking device for locking and unlocking a correspondent more than one accessing means, said locking system comprising:
- an external computer;
- a data bus connected to the external computer, including an additional data channel;
- a plurality of locking devices for each access means, each connected to the bus and each comprising:
- an external bus port connected to the data bus;
- an electronic board 5 connected to the external bus port 3;
- more than one locking means, for locking or unlocking said access means when it is given an input, said locking means connected to the electronic board;
- a sensor for each access means, for sensing if the correspondent access means is open or closed and if the locking means are locked or unlocked, wherein the sensor is connected to the electronic board;
- wherein the electronic board controls each locking means for locking or unlocking a correspondent access means, handles bus communication with the external computer, receives the sensor output which is sent to the external computer, and provides an extra data channel to act as a bridge for the communication between each locking device with the external computer, it further receives instructions from the external computer through the four channel bus and
A locking system as claimed in claim, wherein the commands sent by the computer and processed by each locking device are divided in macro commands, which are sent to the plurality of locking devices and single device commands, which are sent to a specific locking devices, which allows the external computer to control or ask for the status from a specific locking device.
A method for controlling at least one locking device for locking and unlocking a correspondent accessing means, said method comprising:
- providing an external computer;
- providing a data bus connected to the external computer;
- providing at least one locking device for each access means, each controlled by electronic means, said electronic means connected to the data bus and having a sensor to detect if the correspondent access means is locked or closed and if the locking device is locked or unlocked;
- sending commands to each locking device by the computer trough said data bus for controlling said locking device and said locking device responding to the commands received from the external computer.
A method as claimed in clam 7, further comprising sending macro commands, to the plurality of locking devices.
A method as claimed in clam 7, further comprising sending single device commands to specific locking devices, which allows the external computer to control or ask for the status from a specific locking device.
Dependencies are inferred from the claim text.
