するデマンドコントロール装置。An input control section that receives and counts the number of pulses from a power meter with a transmitting device, a time limit section that measures the demand time period and outputs a calculation signal at fixed time intervals, and a target demand value and load cutoff power value are set. predicts the demand value at the end of the demand time period from the setter, the counted value of the input control unit, and the remaining time of the timer, and combines this predicted calculated value with the target demand value set in the setter. a calculation processing unit that calculates the adjusted power based on the comparison calculation and the predicted calculation value;
When the predicted calculation value exceeds the target demased value, the alarm output signal from the calculation processing section is converted into a predetermined transmission signal and outputted to the output terminal, and the adjusted power is set to the cutoff power value set in the setting section. a signal transmission unit that converts the cut-off output signal from the arithmetic processing unit into a predetermined transmission signal and outputs it to the output terminal, and an input terminal is connected to the output terminal of the base unit via a signal line a signal transmission section that receives and demodulates the alarm output signal from the signal transmission section of the connected master device; an address setting section in which the address of the device itself is set; and an alarm output signal demodulated by the signal transmission section. and reads the address of the device itself set in the address setting section, and if the demodulated alarm output signal is given to the device, an alarm is generated according to the content of the demodulated alarm output signal. An alarm unit includes an arithmetic processing section that outputs a signal, an output control section that produces an output that energizes an alarm device according to the content of the alarm signal of the arithmetic processing section, and a signal line is connected to the output terminal of the base unit. a signal transmission and transmission section that receives and demodulates the cutoff output signal from the signal transmission section of the base unit to which an input terminal is connected through the main unit; an address setting section in which the address of the device itself is set; and the signal transmission section.
