摘要： The present invention relates to radio engineering, in particular, to methods for transmitting signals between devices. A technical result provided by the present invention is a simpler design of circuitry for signal transmission between a master devices and slave devices connected thereto.
According to the method for transmitting signals between a master device and at least one slave device, the master device has at least two external first-kind contacts, at least one internal power supply line, a voltage measurement means and at least one external second-kind contact connected directly to the voltage measurement means and, via an impedance, to one internal power supply line. The method comprises: detecting a connection between one of the master device second-kind contacts and a slave device by determining the voltage at such second-kind contact; identifying the master device first-kind contact to which the slave device is connected by setting different voltages at the first-kind contacts and determining the voltage at the second-kind contact; changing the voltage between the first-kind contact to which the slave device is connected and the internal power supply line connected, via the impedance, to the second-kind contact to which the slave device is connected; generating a signal in the slave device by changing resistance between the contacts connected to the master device; receiving the signal in the master device by measuring the voltage at the second-kind contact to which the slave device is connected.-

摘要： Provided is a measurement system for steelworks equipment that can operate with stand-alone power supply even in a location where wiring and maintenance are difficult and can reliably monitor measurement results at a position away from the installation location of a sensor. The measurement system for steelworks equipment comprises: a thermoelectric power generation device; a sensor; a conversion device configured to convert a signal output from the sensor into a signal that is wirelessly transmittable; a wireless transmission device configured to wirelessly transmit the signal converted by the conversion device; a relay device configured to relay the signal transmitted from the wireless transmission device; and a reception device configured to receive one or both of the signal transmitted from the wireless transmission device and the signal relayed by the relay device. The conversion device and the wireless transmission device are driven by power generated by the thermoelectric power generation device.
