TERMINAL FOR REMOTELY MONITORING OPERATED STATE OF POLLUTION PREVENTING FACILITIES

摘要

PURPOSE: A terminal for remotely monitoring an operated state of pollution preventing facilities is provided to reduce an installing cost by adapting a DTMF(Dual Tone Multi-Frequency) signal method, to collect data of operated state with various data detecting modules and to transmit the data into a central control center. CONSTITUTION: An RTC(Real Time Clock)(4) generates a signal in a regular time interval. A memory(12) stores an ID of a corresponding terminal and telephone numbers of a central control center. Many data detecting modules(20a,20b) detect operated state data of a corresponding pollution preventing facility. A transmitting/receiving unit(24) transmits/receives data with the central control center. A DTMF generating unit(23) transmits the data to the central control center through the transmitting/receiving unit by converting to a DTMF signal. A CPU(17) controls trying a call into the central control center with the stored telephone numbers and to transmit the ID and the data.
