Claims

[Scope of Claim for Utility Model Registration] A power meter with a transmitting device that converts the amount of power used at a power receiving point into a transmitted pulse and outputs the transmitted pulse, and the amount of power used runs within a predetermined target demand value. A demand control device that monitors and controls the demand control device receives the threatening pulse from the electricity meter with the transmitting device, and detects the hoax at the end of the de-mand time period based on the counted value and the threshold of the de-mand lower time limit. Calculating and displaying a predicted value of the value, and generating a first alarm signal when the predicted value is predicted to exceed the set target demand value. a computer science department that calculates and displays the adjusted power and generates and displays a second alarm signal and generates and displays a load shedding signal when the calculated and displayed adjusted power value exceeds a preset cutoff power value; A base unit including a signal transmission unit that converts the signal output from the arithmetic processing unit into a rectangular transmission signal and outputs the signal; A signal transmission unit receives and demodulates the alarm signal based on the address address, and outputs a signal to the output control unit according to the content, and the alarm relay unit &2 controls the load. The J. and a control device that performs the same operation as the alarm unit. The units are configured independently and separately, and the master intelligence unit, the alarm unit, and the control unit are configured separately.
Connect the base unit and both units with a dedicated signal line,
By cyclic time division multiplexing transmission between
4 demand controllers, characterized in that they are configured to transmit and receive address signals, alarm signals, control signals and return signals, and the base unit is provided with a control order setting section;
