Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As described above, the applicant of the present invention finds that, in a dual-computer system, an Uninterruptible Power Supply (UPS) is often used to Supply Power to a primary computer and a secondary computer, and a direct connection switch is usually set between the secondary computer and the UPS, so that a problem that the secondary computer cannot correctly execute a Power on/off command according to a command requirement when the secondary computer is powered off again in a Power on process and is powered on again in a Power off process easily occurs. And, applicants have further discovered that in a dual computer system, the host computer can correctly execute the power on/off command because of the internal preset logic. Therefore, if the charging condition of the sub-computer can be made to follow the charging condition of the main computer, the sub-computer can be made to correctly execute the re-on/off command in the process of on/off.
The technical scheme of the invention is schematically described in the following with reference to the attached drawings.
Referring to fig. 1, in one embodiment of the invention there is provided a dual computer power control module comprising:
a main computer power supply control circuit 201 for detecting a power supply input terminal and a port of a main computer, and when detecting that any one of the power supply input terminal and the port of the main computer has a voltage output, making an electrical connection from the UPS to the main computer to energize the main computer; when it is detected that no voltage output exists at the power input end and the port of the main computer, the electric connection from the UPS to the main computer is disconnected so as to power off the main computer;
a secondary computer power control circuit 202 for detecting a power input, a port of a primary computer, and an electrical connection of the UPS to the primary computer, making the electrical connection from the UPS to the secondary computer to power on the secondary computer when a first condition is detected to be satisfied, and breaking the electrical connection from the UPS to the secondary computer to power off the secondary computer when the first condition is detected to be not satisfied; wherein the first condition is: the power input and the port of the host computer have voltage outputs, and the electrical connection of the UPS to the host computer is completed.
As can be seen from the above description of the dual-computer power control module shown in fig. 1, the secondary computer power control circuit does not have a switch directly connected between the UPS and the secondary computer, that is, the UPS does not directly supply power to the secondary computer through the direct-connected switch, and meanwhile, when the power-on and power-off conditions of the secondary computer are controlled, the secondary computer can be controlled based on whether the port of the primary computer has voltage output and the electrical connection between the UPS and the primary computer, so that the charging condition of the secondary computer can follow the charging condition of the primary computer, and therefore, the secondary computer can correctly execute the on-off command in the on-off process.
During the starting process of the main computer, the port of the main computer is powered down briefly due to the logic of the main computer. To avoid the effect of this brief power down on the secondary computer power-on process, in one embodiment of the invention, the secondary computer power control circuitry is further configured to, upon detecting that the second condition is satisfied, complete an electrical connection from the UPS to the secondary computer; wherein the second condition is: the port of the secondary computer has voltage output; the secondary computer power control circuitry is further configured to detect whether the second condition is satisfied upon detecting whether the first condition is satisfied, and to perform disconnection of an electrical connection from the UPS to the secondary computer if it is detected that the first condition is not satisfied and the second condition is not satisfied. It can be seen that in this embodiment, the secondary computer, upon detecting either of the first condition and the second condition being met, will make an electrical connection from the UPS to the secondary computer, causing the secondary computer to be powered on; and the secondary computer is configured to disconnect the electrical connection from the UPS to the secondary computer upon detecting that the first condition is not satisfied and the second condition is not satisfied, such that the secondary computer is powered off.
In one embodiment of the present invention, the main computer power control circuit may be implemented using logic circuitry of an OR gate. Referring to fig. 2, the two inputs of the or gate (denoted as or gate 1) are connected to the status output of the power input and the status output of the port of the host computer, respectively, and the output of the or gate 1 controls the connection and disconnection of the electrical connection from the UPS to the host computer. It can be seen that when there is a voltage output at any one of the power input and the port of the host computer, i.e. the input of the or gate 1 can be represented as 1, 1 or 1, 0, then there is also a voltage output at the output of the or gate 1, i.e. it can be represented as output 1, then the electrical connection from the UPS to the host computer is made to power on the host computer; when the power input end and the port of the main computer have no voltage output, that is, the input of the or gate 1 can be represented as 0 or 0, and the output end of the or gate 1 has no voltage output, that is, the output is 0, then the electrical connection from the UPS to the main computer is disconnected, so that the main computer is powered off, and the function of the main computer power control circuit is realized.
Based on the above-described manner of implementing the main computer power control circuit using an or gate, the sub-computer power control circuit can be implemented in two ways.
In the first mode, the power supply control circuit of the secondary computer is realized by using an AND gate.
Referring to fig. 3, the left or gate in fig. 3 is an or gate 1 for implementing a power control circuit of a main computer, and a right and gate (referred to as an and gate 1) for implementing a power control circuit of a sub computer, three input terminals of the and gate 1 are respectively connected with an output terminal of the or gate 1, a status output of a power input terminal, and a status output of a port of the main computer, and an output terminal of the and gate 1 controls connection and disconnection of an electrical connection from a UPS to the sub computer. It can be seen that when the power input, the port of the main computer and the output of the or gate 1 are all 1, the electrical connection from the UPS to the secondary computer is made to energise the secondary computer; otherwise, the electrical connection from the UPS to the secondary computer is broken to power down the secondary computer, thereby implementing the functions of the secondary computer power control circuit described above.
And the second mode is that the power supply control circuit of the secondary computer is realized by utilizing an AND gate and an OR gate.
During the starting process of the main computer, the port of the main computer is powered down briefly due to the logic of the main computer. In order to avoid the influence of the transient power failure on the starting process of the secondary computer, a secondary computer power supply control circuit can be realized by adopting a second mode.
Referring to fig. 4, the left or gate is the or gate 1 implementing the main computer power control circuit, the middle and gate is designated as the and gate 2, and the right or gate is designated as the or gate 2. Three input ends of the AND gate 2 are respectively connected with the output end of the OR gate 1, the state output of the power supply input end and the state output of the port of the main computer, the output end of the AND gate 2 is used as one input end of the OR gate 2, and the other input end of the OR gate 2 is connected with the state output of the port of the auxiliary computer, namely if the port of the auxiliary computer has voltage output, the input of the other input end to the OR gate 2 is 1. When the power input, the port of the main computer and the output of the or gate 1 are all 1, the output of the and gate 2 is 1, or when the port of the secondary computer has voltage output, namely the output is 1, either of the two conditions can be used for connecting the electric connection from the UPS to the secondary computer so as to electrify the secondary computer; when the power input end, the port of the main computer and the output of the OR gate 1 are not all 1, namely the output of the AND gate 2 is 0, and meanwhile, the port of the auxiliary computer has no voltage output, namely the output is 0, the electric connection from the UPS to the auxiliary computer is disconnected, so that the auxiliary computer is powered off, and the function of the auxiliary computer power supply control circuit is realized.
The use of gates to implement the structure of the present invention has been described above.
In one embodiment of the present invention, the dual computer power control module may also be implemented using relays. Because the relay has a coil and switch contacts, the closing and opening of the switch contacts depends on whether the coil has a voltage output. Based on this, referring to fig. 5, in one embodiment of the present invention, a circuit structure of the dual computer power control module is implemented as follows:
the main computer power supply control circuit includes: a control circuit, a switch contact K12 of the first relay and a switch contact K22 of the second relay; wherein the content of the first and second substances,
the control loop is formed by connecting a control switch K0 and a coil K11 of the first relay in series;
the external UPS, the K12 and the host computer PC1 are sequentially connected in series to form a first connecting circuit;
the UPS, the K22 and the PC1 are sequentially connected in series to form a second connecting line;
the coil K21 of the second relay is connected to a port of the PC1 (COM 1 port shown in fig. 5).
Referring to fig. 5, based on the configuration of the main computer power control circuit described above, the sub-computer power control circuit includes: a switch contact K32 of the third relay, a coil K41 of the fourth relay, and a switch contact K42 of the fourth relay; wherein the content of the first and second substances,
k32 and K41 are connected in series and then connected in parallel at two ends of K11;
one end of K42 is connected to a first connection point on a first connection line, which is located between K12 and PC 1;
the coil K31 of the third relay is connected to a port of the PC1 (COM 1 port shown in fig. 5).
In one embodiment of the present invention, in order to avoid the effect of a short power-down of the main computer during the boot process on the boot process of the secondary computer, referring to fig. 5, the secondary computer power control circuit may further include: the switch contact K52 of the fifth relay;
k52 is connected in parallel at two ends of K42;
the coil K51 of the fifth relay is connected to a port (COM 2 port shown in fig. 5) of the sub-computer PC 2.
Based on the power control module of the dual computer shown in fig. 5, the power supply condition of the secondary computer can be realized to follow the power supply condition of the primary computer, and the problem that the secondary computer cannot correctly execute the on/off command in the on/off process is further solved, which is analyzed as follows:
the following describes how to solve the problem that the secondary computer cannot correctly execute the power on/off command according to the command requirement due to the power off again in the power on process. Referring to fig. 5, first, a power-on command is input, that is, after the power switch K of the left power input 601 is switched to a "power on" state, K12 is closed, and the PC2 detects a rising edge of a signal to execute a power-on process; meanwhile, the PC1 executes a power-on process upon detecting a power-on signal. When the computer is turned on and turned off again, i.e. the power switch at the power input end is turned on and then switched to the "power off" state, as mentioned above, the PC1 will normally execute the power off process, and since the PC1 is powered off after being turned off, no voltage is output from the COM1 port of the PC1, then the following situations will occur:
1. no voltage output exists at the COM1 port, and no voltage output exists at the coils K21 and K31 which are connected in parallel with the COM1 output end, so that the switch contact K22 matched with the coil K21 is disconnected, and the switch contact K32 matched with the coil K31 is disconnected;
2. because the switch at the power input end is opened, after the power input end is switched to a power off state, the switch K0 is also disconnected, and no voltage is output after the coil K11 is powered off, so that the switch contact K12 matched with the coil K11 is disconnected;
3. since the switching contact K32 is open, the coil K41 has no voltage output, and the switching contact K42, which is matched to the coil K41, is open.
Therefore, after the computer is powered off again in the process of starting up, the switch contacts K22, K12 and K42 are all disconnected, so that the PC2 cannot obtain power supply from the UPS and is also powered off, the PC2 is powered off along with the PC1, and the computer is also powered off, so that the PC2 correctly executes a power-off command in the process of starting up the computer.
The following describes how to solve the problem that the secondary computer cannot correctly execute the power on/off command according to the command requirement due to the power on again in the power off process. Referring to fig. 5, after a shutdown command is input, i.e., the power switch K of the left power input 601 is switched to the "power off" state, the PC2 executes a shutdown process; meanwhile, the PC1 performs a shutdown process after detecting a shutdown signal. When the computer is turned on again during the power-off process, i.e., the power switch K of the power input 601 is turned on, and then switched to the power on state, as described above, the PC1 can normally perform the power-on process again after the computer is turned off. Because the PC1 is powered off and then powered on, the PC1 is powered off and then powered on, which results in no voltage output and then voltage output at the COM1 port of the PC1, and thus results in no voltage output and then voltage output at the K31, and accordingly results in the switch K32 being opened and then closed, and accordingly results in the switch K41 being powered off and then voltage output, and accordingly results in the switch K42 being opened and then closed, so that the PC2 detects a rising edge of a signal and the PC2 is powered on, thereby enabling the PC2 to correctly execute a power-on command in the power-off process.
In the following, the circuit structure shown in fig. 5 is used to explain how to avoid the influence of the power-off of the PC1 on the power-on of the PC2 during the power-on process in an embodiment of the present invention.
At the moment of starting up, after the PC1 and the PC2 are both powered on, due to the logic of the PC1, the COM1 port of the PC1 has an instantaneous power failure, so that the coil K31 and the coil K21 do not output voltage, the switch contacts K32 and K22 are disconnected, and after the K32 is disconnected, the coil K41 does not output voltage, so that the switch contact K42 is also disconnected; however, since the switch contact K52 is matched with the coil K51 connected to the COM2 port of the PC2, the closing and opening of the switch contact K52 are determined by the charging condition of the PC2 itself. When the situation occurs, although the switch contacts K42 and K22 are opened when the power of the PC1 is cut off, the switch contacts K12 and K52 are still closed, so that the power supply of the UPS can still be transmitted to the PC2, so that the PC2 still keeps power, and the influence of the voltage jump of the PC1 on the startup of the PC2 is avoided.
In an embodiment of the present invention, there is also provided a power control system of a dual computer, referring to fig. 6, including:
a power switch 701 at a power input 706, a UPS 702, a main computer 703, a sub-computer 704, and a power control module 705 of the dual-computer in any of the embodiments of the present invention;
one end of the UPS 702 is connected to the power switch 701, and the other end is connected to the power control module 705 of the dual computer.
In another embodiment of the present invention, another dual-computer power control system is provided, and referring to fig. 7, on the basis of the dual-computer power control system shown in fig. 6, the dual-computer power control system further includes: an ac/dc conversion circuit 801; the ac/dc converter circuit 801 has an input terminal connected to the power switch 701 and an output terminal connected to a port of the host computer 703.
