Claims

[Scope of utility model registration request]

A control panel is installed near the driver's seat to remotely control onboard electrical equipment, and based on the operation signals from this control panel, a serial code signal consisting of a start code, device selection code, control code, and stop code is generated. a control signal transmitter that generates a signal, frequency-modulates it with a first carrier wave, and sends it as a control signal to control the operation of the on-board electrical equipment; and a control signal transmitter that receives and decodes a monitor signal corresponding to the operating status of the on-board electrical equipment. A device on the driver's seat side that includes a monitor signal receiver and a monitor that displays the decoding results, and a driver's seat side device that is attached to on-board electrical equipment that is distributed throughout the bus to receive and decode the control signal. a control signal receiver that issues an activation signal to operate the on-board electrical equipment based on the result; and a start code, based on the signal emitted by the on-board electrical equipment.
A serial code signal consisting of a device selection code, a monitor code encoded in accordance with the operating status of the in-vehicle electrical equipment, and a stop code is created, frequency-modulated with a second carrier wave, and sent out as the above-mentioned monitor signal. an electric line for supplying electric power for driving the on-vehicle electric equipment and for transmitting signals between the transmitter/receiver of the driver's seat side device and the transmitter/receiver of the on-vehicle electric equipment side device; In the centralized control device for onboard electrical equipment, the control signal and the monitor signal are transmitted in the form of sine waves, the electrical path is configured as a single electrical path, and the control signal transmitter is connected to the onboard electrical equipment. When issuing a control signal to any one of the above, the control signal transmitter operates after confirming that the monitor signal receiver is not receiving the monitor signal from the in-vehicle electrical equipment, and the control signal receiver Equipped with a monitor signal detection circuit that detects the presence or absence of a monitor signal being sent from the in-vehicle electrical equipment side, and while the monitor signal detection circuit detects that a monitor signal is being output from any of the other in-vehicle electrical equipment. 1. A centralized control device for in-vehicle electrical equipment, characterized in that a monitor signal transmitter attached to the electrical equipment is on standby.
