PURPOSE:To detect a physical state and to transmit and receive the data in the physical state, by unifying a data processing part comprising a physical state detecting element, converter, control part, etc. and a transmitting circuit, etc. CONSTITUTION:The physical state detectors such as a temperature sensor TS, humidity sensor HS, etc. have the data transmitting/receiving functions and can be connected to an air conditioning control part ACD via a common line. A polling signal coincident with each proper address is transmitted from the part ACD, and therefore the part ACD can collect individually the data fed from sensors TS and HS. These data can be connected only by a common transmission line L. At the same time, an actuator AT, a start/stop module SS, etc. which have similar functions are prepared. Thus it is possible to control a power plate PP by the actuator AT, a direct control valve MV, a control damper MD and the moduel SSM respectively. |
