Abstract

A data logging apparatus is provided with a separate power supply for driving external sensors, a main module including an acceleration sensor, a memory unit, a control unit embedded with a clock unit for operating a measurement value of the acceleration sensor and storing the operated measurement value into the memory unit in a time series, and a first battery for supplying power to the acceleration sensor, the memory unit, and the control unit; a second battery detachably installed at one side main unit; and a sensor mounting module installed with a plurality of sensor resting units so that sensors can be attached and detached, for receiving the second battery inside so that power of the second battery can be supplied to the sensors installed in the sensor resting units, and transferring measurement signals of the sensors to the control unit.

Claims

1. A data logging apparatus for cables, the apparatus comprising:

a hollow cable mounting member taking the shape of a cylinder with both open sides, in which a cable is securely seated; and

a main module including a three-axis acceleration sensor, a memory, a control unit mounted with a clock unit for operating a measurement value of the three-axis acceleration sensor and storing the operated value into the memory in a time series, a battery for supplying power to the acceleration sensor, the memory, and the control unit,

wherein the cable mounting member comprises a fixed portion, a movable portion installed to be pivoted on a hinge for allowing the cable to be easily mounted into the cable mounting member, and a fixing element for fixing the fixed portion and the movable portion to each other,

a friction member is further installed on an inner circumferential surface of the cylinder composed of the fixed portion and the movable portion to prevent the cable from being moved, due to a frictional force between the cable and the friction member, when the cable is mounted, and

a temperature sensor and a hall sensor are installed to the fixed portion.

2. The apparatus as claimed in claim 1, wherein the main module further includes:

a sensor interface for receiving a measurement signal from the temperature sensor and the hall sensor, converting the measurement signal into a digital signal, and outputting the digital signal to the control unit;

an external interface for receiving an external input, transmitting the external input to the control unit as a signal, and electrically connecting with an external device;

a display unit for receiving a control signal from the control unit and displaying the control signal to the outside; and

a GPS unit for obtaining position information.
