Problems solved by technology

The advantage of this detection method is that the method is simple, easy to implement, and not prone to complex situations; but the disadvantage is that it cannot adjust power consumption and has weak protection capabilities. When the temperature of the chip is too high, there is no automatic processing function, which may easily cause the temperature to continue to rise. And finally lead to abnormal operation of the single board

Embodiment Construction

[0029] Before elaborating the technical solution of the present invention in detail, first introduce the functions of the veneer that will be involved in the technical solution of the present invention, these functions of the veneer are all existing:

[0030] 1. The large power consumption chip on the single board, such as Field Programmable Gate Array (FPGA, Field Programmable Gate Array) chip is composed of several working groups (BANK), each BANK has multiple high-speed channels, and each BANK can Independent switch control;

[0031] 2. When the temperature detection of the chip is abnormal, the system has an alarm mechanism;

[0032] 3. The single board adopts 1+1 protection mechanism, that is, there are two boards, the main board and the backup board, and the main board and the backup board can be switched when the main board works abnormally;

[0033] 4. The chip on the single board is connected with the temperature measuring chip. The temperature measuring chip is used...

Abstract

The invention discloses a method for protecting a veneer. The method includes the following steps: when detecting the temperature of a detected chip exceeds a preset threshold, closing the unused work group of the detected chip and detecting the temperature of the detected chip again; during the second detection process, when detecting the temperature of the detected chip still exceeds the presetthreshold and the veneer of the detected chip is a main board, then sending out a alarm signal, switching from the main board to a spare board, closing all BANKs of the detected chip and continuouslydetecting the temperature. The invention also discloses a device for protecting the veneer. The adoption of the method and the device can reduce the chip power consumption on the veneer and protect the veneer, thus improving the work stability of the veneer.

Description

technical field [0001] The invention relates to veneer protection technology, in particular to a method and device for protecting a veneer. Background technique [0002] Generally, there are some chips with relatively large power consumption on the single board. For example, as a type of single board, the cross-connect board is an important part of the optical data unit (ODU, Optical Data Unit) cross-connect system, and undertakes the task of time slot cross-connection, but the chips used in the cross-connect board consume a lot of power and generate heat. High, so heat dissipation becomes a serious problem. [0003] Since the chip used in the single board consumes a lot of power, it is necessary to detect the temperature of the chip. The existing detection method specifically includes: preset the threshold value of the chip temperature, and when the temperature measuring chip detects that the temperature of the chip exceeds the threshold value, the control unit is notifie...
