Problems solved by technology
[0004] However, in actual use, you may encounter such a problem: the indicator light is not on, which will affect the maintenance of the system by maintenance personnel
Since communication equipment usually does not provide a solution for detecting indicator light failures, this may cause maintenance personnel to take some detours in the process of locating and solving communication equipment failures, delaying troubleshooting time

Embodiment Construction
[0039] In the present invention, a detection instruction is sent to the programmable logic unit (CPLD) on each single board to detect whether the indicating device on each single board is normal, that is, after the CPLD receives the detection instruction, if it can drive the instructions on the single board If the device issues an instruction, it indicates that the corresponding indicating device is normal; if the indicating device on the single board cannot be driven to issue an instruction, it indicates that the corresponding indicating device is faulty.
[0040] figure 2 Is a schematic diagram of the structure of the detection device in the present invention, such as figure 2 As shown, the device includes: a detection unit, a control unit, and an indicating device, wherein the detection unit is used to send a detection instruction to the control unit; the control unit is used to drive the indicating device to issue an instruction according to the received detection instruction...

A detection device and method thereof is disclosed in the present invention. A detection device includes a detection unit, a control unit and an indication device. The detection unit is configured to send a detection instruction to the control unit, and the control unit is configured to drive the indication device to send an indication according to the received detection instruction; if the indication device on a board can be driven to send the indication, it indicates that the corresponding indication device is normal; if the indication device on a board can not be driven to send the indication, it indicates that the corresponding indication device is out of order. The detection unit includes a button and a control bus on a system backplane, or the detection unit includes a network management system and a CPU. The control unit includes a Complex Programmable Logic Device (CPLD) on each board. The detection for the indication device is implemented through setting one button on the communication equipment or through a network management system by the detection device without changing the original communication equipment too much, which is low-cost and easily operational. The detection device can eliminate the hardware failure of indication device on the board very conveniently, and make the maintainers can quickly check a failure when the communication equipment is out of order, which improves the efficiency of the failure elimination, thereby enhancing the maintainability of the system.
Description
Technical field [0001] The present invention relates to detection technology, in particular to a detection device and method. Background technique [0002] The communication equipment is equipped with equipment operation and alarm indicator lights. These indicator lights usually use light emitting diodes (LED, Light Emitting Diode) as the light source. The indicator lights are mainly used to indicate the operation status of the communication equipment and the boards. figure 1 The indicator shown in is a common way to indicate the running status of a board. When the board is running normally, figure 1 The upper green NOM light in the middle and upper part flashes at a frequency of 1 Hz or 0.5 Hz, and the lower red ALM light is off; when the board has an alarm, figure 1 The red ALM light at the bottom of the center lights up to give an alarm. Through the intuitive display of LED, it is more convenient for maintenance personnel to observe and maintain the operating status of the sys...
