<p>PROBLEM TO BE SOLVED: To improve the reliability of information communication by allowing one processor to resend received information in response to an error index. SOLUTION: A multiprocessor system 10 includes a control unit 12, on which a plurality of processors 18, 20, and 26 are mounted. That is, the unit 12 is coupled with a communication medium 14 such as an electric cable and many electric units 18 and a number of functional units 20 are connected with the medium 14. The units 18 are intruder sensors, fire sensors or the like, and the units 20 are control units operated by a solenoid, display devices, or the like. A number of warning output devices 26 are connected with the unit 12 through the medium 24. Each of the processors 18, 20 and 26 analyzes all received messages and repeatedly send messages when a reception-side receiver generates a signal indicating that a received message does not have passed a reliability test.</p> |
