Abstract
Disclosed is a multiplex communication system which comprises a master unit, and a plurality of slave units, wherein the master unit and the plurality of slave units are annularly connected by a signal line, the master unit transmits a request signal to each of the slave units via the signal line, receives a response signal in response to the request signal from each of the slave unit, and an area for which the plurality of slave units can write data is set for the response signal output from the plurality of slave units.
Claims4
A multiplex communication system, comprising:
- a master unit;
- and
- a plurality of slave units connected to the master unit by a signal line annularly, the master unit transmitting a request signal to each of the slave units via the signal line and receiving a response signal in response to the request signal from each of the slave unit, wherein
- the response signal has a data area writable by each of the slave units.

A car-passenger protection system comprising:
- a master unit for judging a scale of collision from a first direction, the master unit transmitting a request signal via a signal line to a plurality of slave units and receiving a response signal in response to the request signal from each of the slave units;
- the plurality of slave units which are connected to the master unit by the signal line annularly and include first and second slave units, the first slave unit judging a scale of collision from a second direction and the second slave unit judging a scale of collision from a third direction;
- and
- a squib operated by a control of the master unit, wherein
- the response signal has a data area writable by each of the slave units, to which data indicating an occurrence of the collision is written when each of the slave units detects the collision.
