Description

Technical Field

[0001] The utility model belongs to the technical field of power supply equipment, in particular to an industrial computer power supply control terminal. Background Art

[0002] Computers and other industrial computers are weak current products, which means that the working voltage of the components is relatively low, generally within plus or minus 12 volts, and it is direct current. The ordinary mains power is 220 volts alternating current, which cannot be used directly on computer components. Therefore, computers, like many home appliances, need a power supply part, which is responsible for converting ordinary mains power into a voltage that can be used by the computer, and is generally installed inside the computer.

[0003] When the existing power supply equipment is powered off, it is difficult to regulate the power supply status and the on / off status of industrial computers such as computers, which makes it easy for the industrial computers to crash due to accidental illegal shutdown. For this reason, an industrial computer power control terminal is proposed here. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an industrial computer power control terminal, which effectively solves the problems existing in the existing power supply equipment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an industrial computer power control terminal, comprising a power supply shell, a display screen is arranged on one side wall of the power supply shell, a fixed frame is arranged in the power supply shell, a battery is arranged in the fixed frame, a circuit board is arranged in the power supply shell on one side of the battery, a relay is arranged on the circuit board, a junction box is arranged on the inner wall of the power supply shell on the side of the circuit board away from the fixed frame, a control board is arranged in the power supply shell on the other side of the circuit board, a control module is arranged on the control board, a first connecting line is arranged at one end of the junction box away from the circuit board, an industrial computer is arranged at one end of the first connecting line away from the junction box, and a second connecting line is arranged on the junction box below the first connecting line.

[0006] Preferably, the display screen is embedded in the side wall of the power supply housing, and the fixing frame is formed on the inner wall of the power supply housing.

[0007] Preferably, the battery is connected to the inner wall of the fixing frame via a slot, the circuit board is connected to the inner wall of the power supply housing via screws, and the battery is connected to an external power supply line and can be charged using an external power supply.

[0009] Preferably, the control board is connected to the inner wall of the power supply casing by screws, the control module is welded to the control board, and the ends of the first connecting wire and the second connecting wire are compressed and connected to the terminal on the junction box by screws. The control module can control the relay and the battery, and can issue power on and off control instructions to the industrial computer.

[0010] Preferably, the end of the first connecting line away from the junction box and the end of the second connecting line away from the junction box are both plugged into the industrial computer, the first connecting line is the DC power supply line of the industrial computer, and the second connecting line is the signal control line of the industrial computer. When the external power supply of the power supply is interrupted, the control module receives a power-off signal and automatically switches to power transmission by the battery, which is similar to the power supply method of a UPS power supply. After the power supply completes the battery power supply switching, the control module sends a power on / off command to the industrial computer through the second connecting line. After receiving the power on / off command, the industrial computer automatically shuts down, thereby avoiding sudden power off and shutdown of the industrial computer due to external power supply interruption, and preventing the industrial computer from causing a system crash due to power off and shutdown.

After the external power supply is restored, the control module of the power supply will work automatically and send a power on / off signal to the industrial computer through the second connecting line to automatically start the industrial computer.

[0023] Among them, the end of the first connecting line 10 away from the junction box 7 and the end of the second connecting line 12 away from the junction box 7 are both plugged into the industrial computer 11. The first connecting line 10 is the DC power supply line of the industrial computer 11, and the second connecting line 12 is the signal control line of the industrial computer 11. When the external power supply of the power supply is interrupted, the control module 9 receives the power-off signal and automatically switches to the battery 4 for power transmission, which is similar to the power supply method of the UPS power supply. After the power supply completes the power supply switching of the battery 4, the control module 9 will send a power on and off command to the industrial computer 11 through the second connecting line 12.

When the external power supply of the power supply is interrupted, the control module 9 receives the power-off signal and automatically switches to the storage battery 4 for power transmission, which is similar to the power supply mode of the UPS power supply. After the power supply completes the power supply switching of the storage battery 4, the control module 9 sends a power on / off command to the industrial computer 11 through the second connecting line 12. After receiving the power on / off command, the industrial computer 11 will automatically shut down, which can avoid the industrial computer 1 being shut down due to the interruption of the external power supply. 1 suddenly shuts down due to power failure, so as to prevent the system crash caused by the shutdown of the industrial computer 11 due to power failure. After the industrial computer 11 is shut down, the control module 9 of the power supply will issue a control instruction again to make the relay 6 cut off the power supply of the battery 4, so as to ensure that the industrial computer 11 is in a completely power-off state after shutdown. After the external power supply is restored, the control module 9 of the power supply will automatically work and send a power-on / off signal to the industrial computer 11 through the second connecting line 12, so that the industrial computer 11 automatically starts. The difference between this power supply device and the traditional UPS power supply is that it ensures the safe shutdown of the industrial computer 11 under the premise of ensuring power failure, so as to prevent the system crash caused by the accidental and illegal shutdown of the industrial computer 11.
