Abstract: A system for performing dimension checkings of mechanical pieces is provided including a contact detecting probe with wireless transmission, for example through a single radiofrequency two-way communication link, to and from a base station connected to an interface unit. The probe includes a logic unit and a memory unit in which reside the values of some operation parameters, for example the transmission frequency and/or the activation mode of the probe. The values of the operation parameters can be modified in a programming phase, according to a method that foresees the wireless transmission of control signals from a manually operated control device—to the probe, for updating of the values among the selectable values of a sequence residing in the probe, and the acquisition of the current value.

Abstract: A system for detecting the position and/or the dimensions of mechanical pieces (3) includes a checking probe (1) with detection devices (2) and a remote transmitter (4), a receiver (7) being remotely placed from the probe to wirelessly receive, from the remote transmitter, pulse signals (5) indicative of the state of the probe. The receiver includes automatic control circuits that detect the presence of noises (NS) on the basis of attributes, e.g. the distribution in amplitude, of the received signal and, consequently, dynamically vary the sensitivity of the receiver, e.g. by acting on the amplification of the received signal or on a threshold (VTH) with which the received signal is compared. The pulse signals can be of optical type and the automatic control of sensitivity can be active in the presence of noise signals emitted by lamps located in the environment.

Abstract: A system for performing dimension checkings of mechanical pieces includes a contact detecting probe (4) with wireless transmission, for example by means of a single radiofrequency two-way communication link (14), with respect to a base station (10) connected to an interface unit (11). The probe includes a logic unit (36) and a memory unit (38) in which there reside the values of some operation parameters, for example the transmission frequency and/or the activation mode of the probe.

Abstract: A system for detecting linear dimensions of mechanical workpieces includes a checking probe with detecting devices, a power supply and a remote transceiver unit. A stationary transceiver unit is located at a distance from the probe, and is adapted for wireless receiving and transmitting to the remote transceiver unit signals, for example, coded optical signals. The stationary unit transmits activation and/or deactivation signals to the probe for controlling the full power supply of the probe circuits, and/or the return to a “stand-by” power state. The remote transceiver unit includes devices adapted for achieving an automatic sensitivity control and other attenuation devices for preventing unwanted consumption of the probe battery energy due to noise signals. Such noise signals could come from fluorescent lamps, for example, causing improper activation and deactivation of the probe circuits.

Abstract: A system for numerical control machine tools comprises contact detecting probes, powered by a battery, that transmit radio-frequency signals to associated interfaces. When the probes are not being utilized for checking cycles, they are in a low-energy consumption state, in other words the circuits of the probes are only partially powered. When the need arises, the circuits of a probe are fully powered by the battery, by a radio-frequency activation signal. The procedure for activating a selected probe includes the sending of a generic activation signal from the associated interface, the transmitting of an identification signal from all the probes that have been activated by the generic signal and the sending of a generic confirmation signal from the interface in reply to the identification signal of the selected probe.

Abstract: A measuring system for a numerical control machine tool comprising a detecting head (3), for contacting a workpiece (1) to be checked and for transmitting an optical coded signal (8) to a remote transceiver unit (11) that, in turn, can transmit an optical switch on signal (10) to the head (3). The transceiver unit (11) is connected, by means of a cable (45) including separate lines (43, 44) for the transmitted and received signals, to an interface unit (12), in turn connected to a computerized numerical control unit (13). In the event that faults occur in the transmission between the head (3) and the interface unit (12), a test takes place so as to identify in which part of the system the fault is located. A test signal is generated by suitable means (38) in the interface unit (12), transmitted from the transceiver unit (11) towards a reflecting surface (16), reflected by the latter, received by the transceiver unit (11) and sent to the interface unit (12).
