1. A self-discovery method for a network of linear sensors, the network comprising a central processing unit and a plurality of linear sensors each comprising a first end and a second end and which are connected together to form a detection line, which is connected to said central processing unit by at least one end of said detection line, the network also comprising at least one accessory, said accessory comprising at least one output allowing to connect a linear sensor by means of one of the ends of said linear sensor,
each linear sensor and/or accessory is characterized by a unique identifier and in that the method comprises at least the following steps:
for each linear sensor and/or accessory:
identifying at least one upstream and/or downstream linear sensor situated upstream and/or downstream of each said linear sensor and/or accessory, the at least one upstream and/or downstream linear sensor being considered as identified if one of its ends is connected to one of the ends of each said linear sensor and/or to the at least one output of the accessory;
sending at least one local request to the at least one upstream and/or downstream linear sensor identified by said linear sensor and/or by the accessory;
sending at least one general request by the central processing unit to the plurality of linear sensors and/or the accessory of the network;
receiving at least one response to the at least one local request by said linear sensor and/or the accessory, the response being composed of the unique identifier of the at least one upstream and/or downstream linear sensor identified by said linear sensor and/or the accessory;
sending at least one response to the general request by said linear sensor and/or by the accessory, the response to the at least one general request sent by the linear sensor comprising the unique identifier of the at least one upstream and/or downstream linear sensor identified by said linear sensor as well as the unique identifier of said linear sensor, and/or, the response to the at least one general request sent by the accessory comprising the unique identifier of the at least one upstream and/or downstream linear sensor identified by said accessory as well as the unique identifier of said accessory; and
processing the at least one response to the general request received from each said linear sensor and/or from each accessory by the central processing unit allowing to reconstitute the logical topology of the network as a function of the unique identifiers received.
