ENVIRONMENT MONITORING DEVICE FOR MULTIPLE DWELLING HOUSE

摘要

PURPOSE:To form an environment monitoring device displaying external environmental information into houses without requiring new wiring by connecting an environment input device and a house display device to a multiple dwelling house communication system. CONSTITUTION:Environment data (such as temperature and humidity) inputted from sensors 14, 15, 10 enter an environment input device 13 in the operation of all environment monitor function and are sent to a transmitter 12. A central controller 1 uses a control line 5 periodically to give a data request. Thus, the transmitter 12 sends the environment data to a control line and the central controller 1 outputs the data to a house display device through the control line 5. The reception section 10 of the display device 9 of each house receives the data and displays on a display section. The display section 11 keeps the data till the succeeding data arrives.
