Abstract

A split detection device includes: a detection unit, which includes a detection casing and a sensor that is mounted inside the detection casing; a processing unit, which includes a processing casing and a processor that is mounted inside the processing casing; a connection unit, which is electrically connected between the sensor of the detection unit and the processor of the processing unit; and a transmission unit, which is electrically connected between the processor of the processing unit and an external device. By setting up the sensor and the processor inside different casings to be separate from each other, influence of the processor on the sensor can be reduced to thereby improve accuracy of detection.

First claim

We claim:

1. A split detection device, comprising:
a detection unit, which comprises a detection casing and a sensor, the sensor being arranged in an interior of the detection casing;
a processing unit, which comprises a processing casing and a processor, the processor being arranged in an interior of the processing casing;
a connection unit, which is electrically connected between the sensor of the detection unit and the processor of the processing unit; and
a transmission unit, which is electrically connected between the processor of the processing unit and an external device;
wherein the sensor comprises a detection circuit board and a detection chip, the detection circuit board being arranged in an interior of the detection casing, the detection chip being mounted to the detection circuit board; and
the processor comprises a processing circuit board and a processing chip, the processing circuit board being arranged in an interior of the processing casing, the processing chip being mounted to the processing circuit board, the processing chip being operable to conduct a processing operation.

2. The split detection device according to claim 1 , wherein the detection casing comprises an accommodation seat and a closure lid, the sensor being arranged in an interior of the accommodation seat, the closure lid attached to and closing an end of the accommodation seat, the accommodation seat comprising a retention section and an out-projection section projecting outward from an end of the retention section, the sensor being located in an interior of the out-projection section, the accommodation seat being configured to fixedly mount to a moving part of a linear transmission device, wherein the moving part is partly recessed to form an insertion channel and the out-projection section is inserted into the insertion channel.

3. The split detection device according to claim 2 , wherein the detection casing of the detection unit is fixedly mounted to an axially-facing surface of the moving part.

4. The split detection device according to claim 2 , wherein the detection casing of the detection unit is fixedly mounted to a radially-facing surface of the moving part.

5. The split detection device according to claim 1 , wherein the detection chip is operable to detect at least one parameter of temperature, vibration, and torque.

6. The split detection device according to claim 1 , wherein the processing unit further comprises a power module, the power module being mounted to the processing circuit board and being operable to regulate a voltage level.

7. The split detection device according to claim 1 , wherein the connection unit and the transmission unit each comprises a physical conductor line for transmission of a signal and electrical power.

8. The split detection device according to claim 1 , wherein the detection unit and the processing unit are spaced from each other by a spacing distance ranging between 1-200 centimeters.

9. The split detection device according to claim 1 , wherein the connection unit comprises a configuration comprising two wireless transmitters, one of the wireless transmitters being mounted to the sensor of the detection unit, the other one of the wireless transmitters being mounted to the processor of the processing unit; and the transmission unit comprises a configuration comprising two wireless transmitters, one of the wireless transmitters being mounted to the processor of the processing unit, the other one of the wireless transmitters being mounted to the external device.
