In addition, it should be mentioned that the above-mentioned setting of the first warning temperature and the second warning temperature is based on the fact that the first processing module 111 is a field programmable logic gate array, and its power consumption is generally 35 watts, and the second The processing module 113 is a system-on-chip, and its power consumption is generally 22 watts, so two different warning temperatures are set, which can be the same in other embodiments, depending on practical design. In addition, the communication connections referred to in the preferred embodiments of the present invention are all wired communication connections, but other embodiments may be wireless communication connections, which depend on practical designs.

The second processing unit 1122 can also be, for example, an existing processor, and can be integrated with the temperature monitoring unit 1121 into the same processor, which depends on the practical design. The second processing unit 1122 is electrically connected to the temperature monitoring unit 1121 and the first processing unit 1111, and has a warning time, and the warning time is, for example, 3 seconds, but is not limited to this in other embodiments.

The second processing module 113 can be, for example, a System On a Chip (SOC), and can communicate with the first processing module 111 through a Peripheral Component Interconnect Express (PCIE) interface. The second processing module 113 includes a third processing unit 1131 and a second temperature sensing unit 1132 . The third processing unit 1131 can be, for example, an existing processor, and is in a second operating state during operation. The second temperature sensing unit 1132 can be, for example, an existing temperature sensor, and is electrically connected to the third processing unit 1131 and communicatively connected to the temperature monitoring unit 1121 .

The working device 12 can be, for example, a motherboard of a server, and can be communicatively connected to the first processing module 111 through a Peripheral Component Interconnect Express (PCIE) interface. The working device 12 includes a management control module 121 and at least one fan 122 (only one is shown in the figure). The management control module 121 can be, for example, a baseboard management controller (BMC), and is communicatively connected to the temperature monitoring unit 1121 and the second processing unit 1122 . The at least one fan 122 is electrically connected to the management control module 121 and is disposed adjacent to the first processing module 111 , and the specific installation position thereof depends on the actual configuration.

The first temperature sensing unit 1112 is used for sensing a first working temperature of the first processing unit 1111 and sending a first sensing signal S1 including the first working temperature.

When the second working temperature is greater than or equal to the second warning temperature, the temperature monitoring unit 1121 sends a second monitoring signal S6 to the second processing unit 1122, thereby triggering the second processing unit 1122 to send the stop operation signal S4 to the third processing unit The unit 1131 is used to make the third processing unit 1131 transition from the second operation state to the stop operation state.

The above-mentioned specific operation of turning off the third processing unit 1131 is the same as the specific operation of turning off the first processing unit 1111 , so it will not be repeated here. The main reason is that the third processing unit 1131 further processes the network transmission data between the data processing device 11 and the working device 12 in practice, while the first processing unit 1111 is in practice. The above is the connection state between the processing and data processing device 11 and the working device 12 , and the connection state between the data processing device 11 and the working device 12 can be protected without immediate power failure.

It should be mentioned that if the second processing unit 1122 does not receive the first monitoring signal S2 sent by the temperature monitoring unit 1121 after the warning time, it can additionally transmit a deceleration signal S9 to the management control module The group 121 is used to trigger the management control module 121 to transmit a fan deceleration operation signal S10 which is a pulse width modulation signal to the at least one fan 122 , so as to decelerate the at least one fan 122 .

In addition, it should be mentioned that the information contained in the fan acceleration operation signal S3 and the fan deceleration operation signal S10 can be specifically defined as increasing the rotation speed of the fan 122 to the set rotation speed and decreasing the rotation speed of the fan 122 to the set rotation speed .

Wherein, in the preferred embodiment of the present invention, after the first processing unit 1111 transitions from the first operation state to the stop operation state, the management control module 121 is further configured to transmit a first restart command S11 to the second processing unit unit 1122, so that the second processing unit 1122 sends a first restart signal S12 to the first processing unit 1111 according to the first restart instruction S11, so as to make the first processing unit 1111 switch from the stop operation state to the first operation state Therefore, in the preferred embodiment of the present invention, the management control module 121 can remotely wake up the function of the first processing unit 1111 .

Similarly, after the third processing unit 1131 transitions from the second operation state to the stop operation state, the management control module 121 is further configured to transmit a second restart command S13 to the second processing unit 1122, so as to enable the second processing The unit 1122 sends a second restart signal S14 to the third processing unit 1131 according to the second restart command S13, so as to make the third processing unit 1131 switch from the stop operation state to the second operation state. Therefore, the present invention is preferably implemented For example, the management control module 121 can remotely wake up the function of the third processing unit 1131 .
