Abstract:
1. A method for monitoring and servicing devices based on one-wire infrared communication, wherein a digital signal is sent between a dedicated device and a target device, and the method comprises: sending a digital signal by a transmitting/receiving line of a one-wire digital input/output of a one-wire IR communication system at the dedicated device to a separator/amplifier system and then sending the signal by way of a TxD line to a signal shaping unit and introducing a time delay and, at the same time, subjecting a feedback unit for the transmitted signal to stimulation by the transmitted signal and blocking a receiving signal, while the transmitted signal is sent on to an IR transmitting element; wherein by way of the IR transmitting/receiving units of the one-wire IR communication system at the side with the dedicated device and the IR transmitting/receiving unit of the one-wire IR communication system at the side with the target device a working range is established in which the IR signal is sent, being received at the side with the target device by the IR receiving element of the one-wire IR communication system of the target device, and sending the signal to an amplifier unit for the received signal, where the received signal is subject to amplification and sent by the RxD line to the separator/amplifier unit, where the signal is transmitted to the one-wire digital input/output of the IR system; sending the signal from the one-wire digital input/output of the IR system by a main communication trunk to respective modules of the target device, wherein a separator/amplifier unit separates the one-wire IR communication system from the rest of the system of the target device and the separator/amplifier unit separates the transmitting signal and the receiving signal, such that by virtue of the input/output of the one-wire IR communication the reception of RxD data is separated from the transmission of TxD data, and by virtue of the IR system the reception of RxD data and transmission of TxD data are connected to the one-wire digital input/output of the IR system, while at the same time in the IR system the feedback unit for the received signal is subjected to stimulation by the received signal and the transmitted signal is blocked, which is sent by the TxD line at the instant when the signal from the separator/amplifier unit is received from the transmitting/receiving line of the one-wire digital input/output of the IR system, and furthermore a delay time is established in the feedback unit between the end of the received data and the releasing of the transmitting/receiving line of the one-wire digital input/output of the IR system.
