In one embodiment of the current monitoring method, the servo device 100 can detect the currents IT1- ITY provided to the respective monitoring target groups 111-11Y by using the detecting unit 121-12Y (step S10), and use the control unit 130 to The respective currents IT1-ITY detected by the detecting unit 121-12Y and the monitoring thresholds of the respective monitoring target groups 111-11Y are respectively compared (step S20). In each comparison, if the control unit 130 determines that the current ITx of the monitoring target group 11x reaches the monitoring threshold corresponding to the monitoring target group 11x, the control unit 130 may perform a current reducing program corresponding to the monitoring target group 11x. (Step S30) to reduce the current ITx supplied to this monitoring target group 11x. Where Y is a positive integer greater than 1, and x can be any positive integer from 1 to Y.

In some embodiments, when the control unit 130 determines in each comparison that the current ITx of the monitoring target group 11x does not reach the monitoring threshold corresponding to the monitoring target group 11x, or after the execution of step S30, the control unit 130 may further determine whether it has completed the alignment of all of the monitoring target groups 111-11Y (step S40). Here, if the control unit 130 determines that it has completed the comparison of all the monitoring target groups 111-11Y, the control unit 130 may return to step S10 to reacquire the currents IT1-ITY of the respective monitoring target groups 111-11Y at this moment. Open another monitor. And if the control unit 130 determines that it has not completed the comparison of all the monitoring target groups 111-11Y, the control unit 130 may return to step S20 to continue performing the comparison of another monitoring target group.

In some embodiments, the control unit 130 may sequentially perform the currents IT1-ITY and the monitoring thresholds of the respective monitoring target groups 111-11Y after acquiring the currents IT1-ITY of the respective monitoring target groups 111-11Y. For example, after the comparison of the monitoring target group 111 is completed, the comparison of the monitoring target group 112 is continued, and so on to the last monitoring target group 11Y. In other embodiments, the control unit 130 may synchronously control the currents IT1-ITY and the monitoring thresholds of the respective monitoring target groups 111-11Y after acquiring the currents IT1-ITY of the respective monitoring target groups 111-11Y. Compare. However, the present invention is not limited thereto. In still other embodiments, the control unit 130 may perform the comparison of the monitoring target group every time a current of the monitoring target group is obtained. For example, after obtaining the current IT1 of the monitoring target group 111, the control unit 130 compares the current IT1 with the monitoring threshold corresponding to the monitoring target group 111. Thereafter, the control unit 130 reacquires the current IT2 of the monitoring target group 112, and compares the current IT2 with the monitoring threshold corresponding to the monitoring target group 112, and so on to the last monitoring target group 11Y.

In an embodiment, the plurality of monitoring target groups 111-11Y can be divided into two types according to the content of the corresponding current reducing program (hereinafter referred to as the monitoring target group A1 of the first type and the monitoring target group of the second type respectively) A2). In some embodiments, the main content of the current reduction program corresponding to each of the first type of monitoring target group A1 may be to reduce the operating frequency of its monitoring target group. The main content of the current reduction program corresponding to each of the second type of monitoring target group A2 may be a shutdown program.

In an embodiment, the monitoring threshold corresponding to each monitoring target group A1 of the first type may include a plurality of monitoring points whose values are different from each other, and the current reducing procedure corresponding to each monitoring target group A1 of the first type is also Can contain multiple subroutines. Here, the number of monitoring points included in the monitoring threshold may correspond to different quantities according to different monitoring densities. In addition, each subroutine of each of the first type of monitoring target groups A1 may correspond to one of the plurality of monitoring points.

In an embodiment of step S20, when the control unit 130 performs the comparison of the monitoring target groups A1 of the respective first types, the control unit 130 may sequentially or simultaneously control the currents ITa and the currents of the monitoring groups A1 of the first types. Corresponding multiple monitoring points are compared. Here, in the comparison of the monitoring target groups A1 of the respective first types, the control unit 130 can monitor (by greater than or equal to) the monitoring target group A1 of the first type according to whether the current ITa of the monitoring target group A1 of the first type reaches (greater than or equal to) Determining whether to perform step S30 according to any one of the plurality of monitoring points, and in an embodiment of step S30, when the control unit 130 determines that the current ITa reaches any one of the plurality of monitoring points, the control unit 130 The corresponding subroutine can be executed according to the monitoring point reached by the current ITa. Here, the control unit 130 is a subroutine corresponding to the monitoring point where the highest value of the monitoring value is loaded and executed according to the monitoring point of the highest value among the one or more monitoring points reached by the current ITa.

In an embodiment, each subroutine of each of the first type of monitoring target group A1 reduces the effect of the current ITa of the monitoring target group A1 of the first type and the size of the corresponding monitoring point among all the monitoring points. Related. For example, the subroutine corresponding to the monitoring point with a large value can achieve the effect of reducing the current ITa greater than the subroutine corresponding to the monitoring point with a small value, which can achieve the effect of reducing the current ITa, wherein the corresponding monitoring point The subroutine makes the difference between the current ITa after the reduction and the current value of the current ITa before the reduction is the effect of reducing the current ITa, but the present invention is not limited thereto. In another embodiment, the contents of the respective sub-programs of the monitoring target group A1 of the first type may be different from each other, and each sub-program has a priority weight, and the priority is the same as the monitoring point corresponding to each sub-program. The size is ranked in all monitoring points. For example, a subroutine corresponding to a monitoring point having a small value has a priority greater than a priority of a subroutine corresponding to a monitoring point having a large value.

In some embodiments, among all the monitoring points of the monitoring target group A1 of the first type, the subroutine corresponding to the monitoring point with the largest value may be a shutdown program to stop the operation of the monitoring target group A1 of the first type. . In an embodiment, the shutdown program may only disable the operation of the monitoring target group A1 of the first type. In another embodiment, the shutdown process closes the operation of another monitoring target group related to the monitoring target group A1 of the first type, in addition to the operation of the monitoring target group A1 of the first type. . For example, when the first type of monitoring target group A1 can be composed of one or more system fans, the related another monitoring target group can be composed of one or more motherboards, and when the control unit 130 determines this When one type of monitoring target group A1 reaches the monitoring point of the largest value and needs to perform the shutdown procedure, the control unit 130 causes the one or more system fans to stop operating, and further causes one or more related One or more motherboards of the system fan are down. However, the present invention is not limited thereto. In still another embodiment, the shutdown procedure may further shut down the operation of the entire servo device 100.

In some embodiments, the first type of monitoring target group A1 may be a monitoring target group composed of one or more system fans, or a monitoring target group composed of one or more motherboard modules, but The invention is not limited thereto, and the monitoring target group A1 of the first type may be composed of one or more targets whose current is reduced by lowering the operating frequency thereof, wherein the more the operating frequency of the monitoring target group is lowered, the lowering is performed. The effect of the corresponding current is greater. In addition, the monitoring target group A2 of the second type may be a monitoring target group composed of one or more hard disks, but the present invention is not limited thereto, and the monitoring target group A2 of the second type is directly executed by the shutdown program. Composed of one or more targets that reduce their current.

In some embodiments, when the monitoring target group A1 of the first type is composed of a system fan, the maximum monitoring point among the plurality of monitoring points corresponding to the monitoring target group A1 of the first type may be 70 amps. . In addition, when the first type of monitoring target group A1 is composed of the motherboard module, the maximum monitoring point among the plurality of monitoring points corresponding to the monitoring target group A1 of the first type may be 50 amps, but The invention is not limited thereto.

In an embodiment, it is assumed that a plurality of monitoring points corresponding to the first type of monitoring target group A1 composed of the system fan are 60 amps (A), 65 amps and 70 amps, respectively, and the subroutine corresponding to the control point 60 amps In order to cause the first type of monitoring target group A1 to reduce its operating frequency by 1/4, 65 amps causes the first type of monitoring target group A1 to decrease its operating frequency by 1/2, and the subroutine corresponding to 70 amps is executed. Shutdown procedure. When the detected current ITa is 65 amps, since the current ITa is greater than or equal to the monitoring point of 60 amps and the monitoring point of 65 amps, the control unit 130 performs step S30, and according to the detected current The largest monitoring point reached by ITa, the monitoring point of 65 amps, loads and executes the detected sub-procedure corresponding to the monitoring point of 65 amps, which is the highest monitoring point reached by the current ITa. Therefore, the control unit 130 can execute a subroutine that reduces the 1/2 operating frequency to reduce the current ITa of the monitoring target group A1 of the first type by causing the operating frequency to decrease to 1/2. In some embodiments, under the condition of no abnormality and no other factors, when the operating frequency is reduced to 1/2, the current ITa of the monitoring target group A1 of the first type can be substantially reduced to the original 1 /2. For another example, if the detected current ITa is 72 amps, because the current ITa is greater than or equal to 60 amps of monitoring points, 65 amps of monitoring points, and 70 amps of monitoring points, at this time due to the detected current ITa The monitoring point that has reached the maximum response value is 70 amps, and the control unit 130 responds to the monitoring point with the largest value and executes the subroutine of the shutdown program accordingly to reduce the monitoring target group A1 of the first type by causing the operating frequency to decrease to zero. Current ITa.

In some embodiments, when the first type of monitoring target group A1 is a monitoring target group composed of one or more system fans, and the control unit 130 executes any subroutine of the first type of monitoring target group A1. (If the subroutine that executes the shutdown procedure is not included), the control unit 130 can directly reduce the operating frequency of the system fan in the monitoring target group A1 of the first type, that is, the rotational speed of the system fan, for example, by adjusting the output to The system fan is used to control the PWM duty cycle of the fan speed to reduce the current ITa. However, the present invention is not limited thereto, and the control unit 130 may first detect the corresponding to the detected value. The operating frequency of the core system of the target group A1 is monitored to lower the internal temperature of the servo device 100 to indirectly reduce the rotational speed of the system fan in the monitoring target group A1 of the first type by lowering the internal temperature. Here, the core system can be a central processing unit (CPU). Moreover, when there are multiple central processing units on the same motherboard in the server device 100, the control unit 130 only processes one or several central processing units corresponding to the first type of monitoring target group A1 among the plurality of central processing units. The operating frequency of the unit is varied without changing the operating frequency of all central processing units. In one embodiment, it is assumed that the plurality of monitoring points corresponding to the first type of monitoring target group A1 composed of the motherboard module are 40 amps, 45 amps, and 50 amps, respectively, and the subroutine corresponding to the monitoring point 40 amps is Causes the monitoring target group A1 of the first type to reduce its operating frequency by 1/2, and the monitoring point of 45 amps causes the monitoring target group A1 of the first type to close/stop execution of the program that it is executing and has a lower priority, such as closing/ Stop executing some programs that are not important and will not cause their system to stagnate, and the subroutine corresponding to the monitoring point of 75 amps is to execute its corresponding shutdown procedure. When the detected current ITa reaches a monitoring point of 40 amps (ie, the current ITa is a monitoring point greater than or equal to 40 amps and less than 45 amps), the control unit 130 can perform a reduction of 1/2 at this time. A subroutine of operating frequency to reduce current ITa. When the detected current ITa reaches a monitoring point of 45 amps (ie, the current ITa is a monitoring point greater than or equal to 45 amps and less than 50 amps), the control unit 130 can execute the corresponding subroutine content at this time. Shut down/stop execution of programs with lower priority, such as shutting down/stopping certain programs that are not important and will not cause the system to stall, to reduce the current ITa. When the detected current ITa reaches a monitoring point of 50 amps (ie, the current ITa is a monitoring point greater than or equal to 50 amps), the control unit 130 may execute a subroutine for performing a shutdown procedure to reduce the current. ITa.

In an embodiment, the monitoring threshold corresponding to each of the second type of monitoring target groups A2 may include a plurality of monitoring points whose values are different from each other. Here, among the plurality of monitoring points corresponding to the monitoring target group A2 of the second type, the monitoring point with the largest value may correspond to the current reducing program of the monitoring target group A2 of the second type, and the remaining monitoring points only The state of the current ITb of the monitoring target group A2 of the second type is detected, and does not individually correspond to the current reducing procedure of the monitoring target group A2 of the second type. In other words, the control unit 130 loads and executes the current reduction procedure of the monitoring target group A2 of the second type only when the current ITb reaches (greater than or equal to) the monitoring point having the largest value.

In an embodiment, among the plurality of monitoring points corresponding to the monitoring target group A2 of the second type, except that the monitoring point with the largest value can correspond to the current reducing program of the monitoring target group A2 of the second type, the rest The respective monitoring points can respectively correspond to different weight values, so that the control unit 130 can repeatedly change according to the magnitude of the current ITb of the second type of monitoring target group A2 at such monitoring points (excluding the monitoring point with the largest numerical value). The total weight value obtained determines whether the monitoring target group A2 of the second type has an abnormality, and determines an abnormality when the total weight value exceeds the preset total value, and directly executes the lowering corresponding to the monitoring target group A2 of the second type. Current program.

For example, suppose that the monitoring points corresponding to the second type of monitoring target group A2 are 60 amps, 80 amps, and 100 amps, respectively, wherein the highest monitoring point 100 amp corresponds to the current reducing program, and the monitoring point is 60 amps. To the weight of 0.2, the monitoring point 80 amp corresponds to a weight of 0.5, the initial value of the total weight value is 0, and the preset total value is 1. Here, the control unit 130 may accumulate the weight 0.2 to the total weight value when it is determined that the current ITb of the monitoring target group A2 of the second type reaches the monitoring point of 60 amps, and when it is determined that the current ITb reaches the monitoring point of 80 amps, The weights 0.5 are accumulated to the total weight value. Therefore, if the value of the current ITb detected by the control unit 130 in the four detections is 65 amps, 83 amps, 70 amps, and 90 amps, respectively, the control unit 130 can determine the current ITb in the first detection. The monitoring point is 60 amps and the value of the total weight value is changed from 0 to 0.2. In the second detection, the value of the total weight value was changed from 0.2 to 0.7 by determining that the current ITb reached the monitoring point of 80 amps. In the third detection, the value of the total weight value was changed from 0.7 to 0.9 because it was determined that the current ITb reached the monitoring point of 60 amps. Finally, in the fourth detection, the value of the total weight value was changed from 0.9 to 1.4 by determining that the current ITb reached 80 amps. At this time, the control unit 130 may determine that an abnormality occurs because the total weight value is greater than the preset total value, and directly execute the current reduction program corresponding to the monitoring target group A2 of the second type.

In an embodiment, the current reduction program corresponding to each of the second type of monitoring target group A2 may also include a plurality of subroutines, and each subroutine may correspond to one of the plurality of monitoring points. In this case, each subroutine can be a shutdown program, and each subroutine can be used to cause at least one target of the second type of monitoring target group A2 to stop operating. Therefore, the control unit 130 can be based on the second The monitoring point reached by the current ITb of the type monitoring target group A2 executes a corresponding subroutine to reduce the current ITb of the monitoring target group A2 of the second type by stopping the operation of the corresponding at least one target. However, the present invention is not limited thereto. In another embodiment, each subroutine is also a shutdown procedure for causing at least one target of the second type of monitoring target group A2 to stop operating, but the monitoring point with the largest value The corresponding subroutine is a shutdown procedure for causing all targets in the monitoring target group A2 of the second type to stop operating.

In an embodiment, when the current reducing program executed by the control unit 130 is a shutdown program, the control unit 130 may record the monitoring target group, the current value, and the like that cause the shutdown process to be performed as an error message for maintenance. The error of the servo device 100 can be excluded based on the error message during subsequent maintenance.

FIG. 5 is a schematic diagram of an embodiment of the detecting unit of FIGS. 1 to 3. Referring to FIG. 1 to FIG. 5, the internal structures of the detecting units 121-12Y are substantially the same. Therefore, the description will be made by taking an embodiment represented by the detecting unit 12x. Where Y is a positive integer greater than 1, and x can be any positive integer from 1 to Y.

The first port P1x of the detecting unit 12x is coupled to the power unit 140, the second port P2x is coupled to the corresponding monitoring target group 11x, and the third port P3x is coupled to the control unit 130. Here, the first port P1x is used to receive the current ITx provided by the power unit 140 to the corresponding monitoring target group 11x, and the second port P2x is used to provide the current ITx to the monitoring target group 11x to which it is coupled, and the third port P3x The value of the current ITx detected by the detecting unit 12x is transmitted to the control unit 130.

The monitoring target group 11x is coupled to the second port P2x. The processing module 12x1 can be used to detect the magnitude of the current ITx transmitted to the second port P2x via the first port P1x and the switch module 12x2, and transmit the magnitude of the detected current ITx to the control unit 130 via the third port P3x. . In addition, the processing module 12x1 can compare the detected current ITx with a highest threshold corresponding to the monitoring target group 11x to borrow when the current ITx reaches (greater than or equal to) the highest threshold of the monitoring target group 11x. The control switch module 12x2 disconnects the connection path between the first port P1x and the second port P2x, thereby stopping the power supply unit 140 from supplying the current ITx to the corresponding monitoring target group 11x, and causing the corresponding monitoring target group 11x to The current ITx for its operation is not received and the operation is stopped, so that the monitoring target group 11x coupled to the second port P2x is damaged by the operation of the excessive current ITx. For example, in an embodiment, when the processing module 12x1 determines that the current ITx reaches the highest threshold, the processing module 12x1 can generate a disconnection signal to the switch module 12x2, so that the switch module 12x2 can be disconnected according to the open signal.

Here, the sensor Rx is used to sense the current ITx, and the processor Dx is used to report the magnitude of the current ITx to the control unit 130, and is used to cause the switch module 12x2 when the magnitude of the current ITx reaches the maximum threshold. The link path between the first port P1x and the second port P2x is disconnected.

In some embodiments, the sensor Rx can be implemented with a resistive element to apply a series resistance detection method to sense the magnitude of the current ITx. In addition, the processor Dx can be implemented in an integrated circuit manner, and the processor Dx can obtain the magnitude of the current ITx according to the resistance value of the resistance element of the sensor Rx and the voltage across it, but the present invention is not limited to In other embodiments, the sensor Rx may also apply a current direct current resistance (DCR) detection method, a Hall effect detection method, or the like, or any suitable detection method to sense a current sensor of a current ITx size.

In some embodiments, the highest threshold of the monitoring target group 11x is greater than its corresponding monitoring threshold. In addition, the switch module 12x2 can be implemented by using one or more transistors, transmission gates (TG) and the like.

In some implementations, the storage unit can be implemented by one or more storage elements. Each storage element can be a non-volatile memory such as a read only memory (ROM), a flash memory, an electronic erasable rewritable read only memory (EEPROM), or the like, or a volatile memory, such as Random access memory (RAM), etc.
