There is provided a controlling communication system which includes a control device for transmitting a control signal, an object-side communication device mounted on a controlled object for receiving the control signal, and a drive control device for controlling the controlled object, and which can set a failsafe function of the object-side communication device using the control device, wherein a voltage reference value and a detection time reference value set by the control device are transmitted to the object-side communication device and are stored in a memory unit of the object-side communication device, and wherein the object-side communication device judges if the battery state meets a requirement for activating a failsafe function by referring to the voltage reference value and the detection time reference value stored in the memory unit.

Controlling communication system

The present invention provides a steering communication system being able to individually obtain a telemetry data from a steered-object communication devices mounted on the steered-object. An arbitrary identification number assigned to a plurality of steered-object communication devices mounted on a steered-object at the time of pairing-setup is associated with the equipment ID of a pairing object. When performing transmission request of a telemetry data, a steering signal adding the transmission request information and the own identification number is transmitted. The steered-object communication device judges signal classification of the inputted control signal. When the steering signal adding transmission request information and the own identification number is inputted, the steered-object communication device transmits a telemetry data signal adding the telemetry data as an answer signal to a steering communication device.

An oscillation device includes a reference oscillation unit for generating an oscillating signal of a specific frequency; a voltage-controlled oscillation unit for generating a output oscillation signal whose frequency is dependent on a control voltage; a phase comparing unit for detecting a phase difference based on the oscillating signal and the output oscillation signal; a digital value storage unit for storing therein a phase difference signal corresponding to the phase difference as a digital value; a sample holding unit for intermittently renewing and maintaining a hold signal in accordance with the digital value; and a control unit. The control unit controls the reference oscillation unit, the phase comparing unit and the digital value storage unit to be started or stopped, and also switches the control voltage to the phase difference signal or to the hold signal.
