Embodiment 1

[0060] Refer to figure 1 The amplified and separated sensor according to the first embodiment of the present invention is a sensor constructed by connecting the sensor head 1 and the signal processing unit 2 with one or two or more sensor cables.

[0061] As the sensor head, various sensor heads such as displacement sensors, vision sensors, non-contact sensors, microwave sensors, and length measuring sensors can be used.

[0062] The signal processing unit 2, in this example, is a sensor interface 21 for taking in the sensor signal from the sensor head 1 and sending a control signal to the sensor head 1 via a transmission path, and an FPGA (Field Programmable Logic Circuit) as a programmable logic circuit. Programmable Gate Array: Field Programmable Gate Array) 22, a CPU 23 composed of a microprocessor as the main body, and an input / output interface 24 are connected in series.

[0063] Using FIG. 2, an amplification and separation type sensor using the sensor cable of the present...

Embodiment 2

[0081] In the above-mentioned first embodiment, the cable length is extended by connecting multiple cables, and at the same time, a waveform shaping circuit (such as a combination of a serial / parallel converter and a parallel / serial converter) is inserted in each cable portion to improve Voltage drop due to passivation of the waveform and impedance. In this case, if the signal processing unit or the sensor head as the transmitting end does not detect a synchronization deviation in the serial communication between adjacent cables, the operation of the sensor may malfunction. Generally, an IC used as a serial / parallel converter in such serial communication has a function of detecting a synchronization deviation of serial communication and generating a predetermined binary signal. However, if the synchronization deviation detection signal generated by the IC for serial / parallel conversion of each cable is separately reported to the sensor head or the signal processing unit as the tra...

Abstract

A cable includes a first connector half holding a conductor terminal, a second connector half holding a conductor terminal, an electric cord electrically connecting the conductor terminal of the first connector half to the conductor terminal of the second connector half, and a waveform shaping circuit performing waveform shaping of a signal passing through the electric cord, and the first and second connector halves are structured to allow attachment to and detachment from each other.

Description

Technical field [0001] The present invention relates to a sensor cable used to connect the sensor head and the signal processing unit of an amplified and separated sensor (ap-separated type sensor). In particular, it relates to the ability to connect a plurality of cables as a whole to easily change the total length and even the total length. A sensor cable that can be very long and can transmit accurate signals at high speed and an amplified and separated sensor equipped with the cable. Background technique [0002] As devices called "sensors", various sensors with different operating principles, such as displacement sensors, vision sensors, non-contact sensors, microwave sensors, and length measuring sensors, are known. In addition, even sensors with the same operating principle have various specifications. [0003] However, the status quo is that with the recent technological development, the purpose of use and the state of use of these sensors are diversified, and along with ...
