Abstract
A measuring device in a mobile rack for hard disk is fixed to a window opening at the front side of the inner rack in the mobile rack and comprises a circuit board and a controller on the circuit board. The circuit board and the controller connect and control an input end, one or more output ends, at least one temperature sensor rod, and a display respectively. Therefore, the temperature of the hard disk in the mobile rack can be measured, a default temperature can be reset, and the speed of the respective fan can be measured. Moreover, once the fans is abnormally running and the temperature in the hard disk is higher than the default value, a buzzer may send out a warning sound respectively.
Claims10
A mobile rack with measuring device for hard disk, comprising
- an inner rack attached with a fan, having a window opening at a front side thereof for fixing the measuring device, being provided with a connector, and receiving the hard disk;
- and
- a stationary rack with or without fans, movably receiving the inner rack;
- wherein, the measuring device further comprising a circuit board and a controller on the circuit board;
- characterized in that the circuit board and the controller join and control the following components:
- an input end, connecting with the connector on the inner rack for taking power source externally;
- one or more output ends, connecting with the fan in the inner rack and/or the fan on the stationary rack, and feeding the respective speed of the fans back to the controller for sensing the rotation frequency;
- at least one temperature sensor rod, extending from the circuit board to the hard disk in the inner rack for keeping in a state of sensing the temperature in the hard disk so as to be read by the controller;
- a display, being disposed at the window opening, receiving instructs of the controller, and appearing updating state of the respective fan and the temperature of the hard disk.
