Abstract

A method of configuring a lock system comprising a plurality of lock system devices comprises the following steps: defining a plurality of command and status messages, wherein each of the messages has a specific function when received by a device, defining a plurality of device types, wherein each of the types can send predetermined command and status messages, sending a claiming message from each device, wherein the claiming message from a specific device comprises information relating to the predetermined messages that the specific device can send, and storing, in each of the devices, the information relating to the predetermined messages that every other device can send. By this method, a simple lock system can be set up without involvement of the person installing the system. A lock system and a lock system device using this method are also provided.

Claims

1. A method of configuring a lock system comprising a plurality of lock system devices, said method comprising the following steps:

a) defining a plurality of command and status messages, wherein each of said command and status messages has a specific function when received by a device,

b) defining a plurality of device types, wherein each of said device types can send predetermined command and status messages of said plurality of command and status messages,

c) sending a claiming message from each of said plurality of devices, wherein said claiming message from a specific device comprises information relating to said predetermined command and status messages that said specific device can send, and

d) storing, in each of said plurality of devices, said information relating to said predetermined command and status messages that every other device can send.

2. The method according to claim 1, wherein each of said command and status messages are assigned a unique index value.

3. The method according to claim 1, wherein each of said command and status messages are related to specific device types.

4. The method according to claim 1, wherein said claiming message comprises an attribute indicator indicating belonging to either or both of two different groups (Group 1, Group 2).

5. The method according to claim 1, wherein said claiming message comprises a binary field wherein each bit specifies whether a corresponding message can be sent.

6. The method according to claim 1, wherein said claiming message comprises an attribute indicator indicating whether a sub-device will follow or not.

7. The method according to claim 1, comprising classifying each device as either activator, actuator, or sensor, wherein an activator is arranged to send commands to an actuator, an actuator is arranged to perform a mechanical activity, and a sensor is arranged to provide sensor status information.

8. An electronic lock system device, comprising:

a processing unit,

an electronic memory connected to said processing unit,

an input/output port,

wherein said device, when powered on, sends a claiming message on said input/output port comprising information relating to predetermined command and status messages that said device can send, and

stores information from claiming messages received through said input/output port relating to said predetermined command and status messages that other devices can send.

9. The device according to claim 8, comprising a group switch indicating the belonging to either or both of two different groups.

10. A lock system comprising a plurality of lock system devices, all of said devices being interconnected by means of a bus, and wherein each of said devices comprises:

a processing unit,

an electronic memory connected to said processing unit, and

an input/output port,

and wherein each device, when powered on, sends a claiming message on said input/output port comprising information relating to predetermined command and status messages that said device can send, and

stores information from claiming messages received through said input/output port relating to said predetermined command and status messages that other devices can send.
