Description

Output power management method and device thereof

The present invention relates to an output power management method and apparatus thereof. Specifically, the present invention relates to an output power management method and apparatus thereof, and has the function of monitoring the output end by smart scheduling measurement.

With the increasing demand for resources from the Internet and the desire of enterprises to reduce the cost of their own investment in software and hardware through network services, and thus improve administrative efficiency, the management of the equipment room of the enterprise itself or the service provider will become more and more Significantly important.

A conventional power management device is mainly configured by means of a power meter corresponding to an outlet port. When the same number of meters are used, the load at the output can be measured immediately, but it must cost a lot of hardware. At present, the main function of the power management product is to measure the current, voltage, power and watt-hour. When each output terminal needs to set a meter, then 20 jacks need a total of 20 meters, so the hardware usage will be Greatly improve.

Although it is possible to reduce the cost of hardware by using an electric meter smaller than the number of outputs, if this method is used for monitoring, it is necessary to perform a load measurement on each output by polling. However, if the polling method is used for measurement, since the polling time is equal, if an emergency event occurs at the output end, it may be difficult to find it immediately, or it may have been a period of time before the discovery, and it is too late to dispose of it. And then the danger occurs.

In addition, the traditional power management device can only measure the power consumption of the output, and can not immediately respond to the information management personnel for potential problems in the circuit such as load overload, power jump, host overheating or environmental data changes. The equipment room cannot be trouble-shooted in an efficient manner.

An object of the present invention is to provide a power management device that can use less than the number of output power management devices to measure the load of each output by intelligent scheduling, thereby achieving the goal of saving hardware costs.

Another object of the present invention is to provide a power management method for classifying different priority states according to the load status of each output terminal, so that the output terminal with a higher priority state obtains more measurement times.

The output power management method comprises the steps of: obtaining a priority state of each of the plurality of outputs; measuring a load state of the output state satisfying a specific condition; and outputting the output The load state is compared with a preset condition. If the load state of the output end is consistent with the preset condition, the priority state of the output end does not need to be reset. If the load state of the output end does not match the preset condition, then Reset the priority of the output.

The power management device includes a scheduling module, a measurement module, and a setting unit. The scheduling module is configured to obtain a priority state of each of the plurality of outputs. The measurement module is coupled to the scheduling module, and measures a load state of the output state that meets a specific condition. The setting unit is coupled to the measurement module. If the load state of the output end matches the preset condition, the priority state of the output end does not need to be reset, and if the load state of the output end is compared with the preset condition, the result is compared. If it does not match, you need to reset the priority status of the output.

The invention provides an output power management method and device thereof. In a preferred embodiment, the power management device can be used in a rack device to measure the output load of the power device to ensure safe use of power in the equipment room. The power management device can also be used to monitor the temperature and humidity in the equipment room to perform environmental control.

As shown in FIG. 1, the power supply device 10 has a plurality of output terminals 100-104. Each of the outputs 100-104 can provide the power required by an electronic device. The electronic device 105 can be a computer, a screen, a router, an air conditioner, or an electronic hygrometer, but is not limited thereto. The respective output terminals 100 to 104 of the power supply device 10 are connected to the power management device 200, and the power management device 200 monitors the power usage of each of the output terminals 100 to 104. In this embodiment, the output terminals 100-104 are sockets, and have at least two jacks for electrically connecting with the plugs of the electronic device 105. In one embodiment, the power management device 200 is a software written by a program, and has a function of checking the priority status of each of the output terminals 100 to 104 in order or in a specific setting order. After the power states of the output terminals 100-104 are connected to the power management device 200, the scheduling module 202 obtains from the storage unit 208 the priority state stored by each of the output terminals 100-104 during the last measurement.

The priority state is determined according to the preset load interval range in which the load state of each of the output terminals 100-104 is located. In this embodiment, the priority state is set by the setting unit 206 for each load state of the output terminals 100-104. The priority status of the output terminals 100 to 104, the correspondence between the load status and the priority status is obtained according to a preset condition, that is, the setting unit 206 regards whether the load status is within a certain range of the preset condition. And determine the priority state of the load state in this measurement. For example, if the preset condition has three load intervals, each load interval corresponds to a priority state, and the setting unit 206 determines that the load status bit of an output terminal 100-104 is in the first load interval, if the first A load interval belongs to the first priority state, and the output terminal corresponds to the first priority state. It should be noted that the first priority state, in this embodiment, refers to the load that the output has, and the load relative to the other outputs is relatively large. Therefore, if three load intervals are taken as an example, the load of the first priority state is greater than the load of the second priority state, and the load of the second priority state is greater than the load of the third priority state. After the setting unit 206 is set, the message is transmitted to the storage unit 208, and the set priority state is recorded by the storage unit 208, and then the next measurement is performed. The scheduling module 202 determines whether the priority state of each of the output terminals 100-104 is in the first priority state, for example, when the priority state of the output terminals 100-103 is the first priority state, and 104 is the non-first priority state, Then, a signal is sent to the measurement module 204. Then, the measurement module 204 measures the load status of each of the output terminals 100-103 belonging to the first priority state according to the number order of the output terminals.

Figure 2 shows a flow chart of the power management method. As shown in FIG. 2, step S1010 includes: obtaining a priority state of each of the plurality of outputs. The priority status is from the setting result stored by the storage unit 208 for the previous measurement. Please refer to FIG. 1 at the same time, and then proceed to step S1012. When the priority state of the output terminal 100 is the first priority state, the load state of the output terminal having the priority state satisfying a specific condition is measured in step S1020. In an embodiment, the specific condition is whether the priority state of the output is the first priority state. That is, step S1020 is to measure the load state of the output terminal 100 in the first priority state. The scheduling module 202 sends a message to the measurement module 204, so that the measurement module 204 measures the load state of the output terminal belonging to the first priority state. The load state may be a value such as current, voltage, power, watt-hour, temperature or humidity. On the other hand, if the priority state of the output terminal is not the first priority state, in order to avoid monitoring the output terminal of the non-first priority state, the scheduling module 202 directly sends a message to the setting module 206 to make the setting module. The priority state of the output that is not in the first priority state is raised by one level, and the outputs that are not in the first priority state can also be the first priority state and monitored.

Step S1022: Comparing the load state measured by the output end belonging to the first priority state with the preset condition, and generating a comparison result. The preset condition is preferably a comparison form, which includes a range of ranges set with respect to different load state values, and different range ranges respectively correspond to different priority states. The measurement module 204 compares the load state with the preset condition, and obtains a priority state corresponding to the load state.

At this time, the output of the first priority state may be changed, and step S1030 includes: setting the unit to set the priority state. The setting unit 206 sets the priority state of the load end after the measurement is set based on the comparison result C. If the range of the range corresponding to the value of the load state still corresponds to the first priority state, the setting unit 206 does not need to reset the priority state after receiving the comparison result C; if the range corresponding to the value of the load state is other priority states, then The setting unit 206 will reset the priority state after receiving the comparison result C. After the setting is completed, the storage unit 208 records the priority status of the output terminal, and then switches to the next output terminal for checking. This makes it possible to save the measurement time of the power management device 200 for the output of the non-first priority state.

Step S1050 includes: storing a priority status. And step S1070 includes: switching to the next output. After the setting unit 206 is set, the storage unit 208 records the priority state of the set output terminal, and switches to the next output terminal, so that the scheduling module 202 checks the priority state of the next output terminal. After the scheduling module 202 checks one pair of each output terminal 100~104, the next cycle measurement is performed. In this embodiment, the inspection mode of the scheduling module 202 is preferably based on the number of each of the output terminals 100-104 in the equipment room. However, in other embodiments, the manner of checking the scheduling module 202 may also be performed according to the priority status of the previous measurement result. That is, the scheduling module 202 first checks all the output terminals of the first priority state, for example, 100~102, and then checks all the output terminals 103 of the second priority state, and then checks all the output terminals 104 of the third priority state, Continue to check in this way.

3 is a schematic diagram of an embodiment of a power management device with additional components. As shown in FIG. 3, the power management device 200 can also be combined with a switch detecting device 300. The switch detecting device 300 can be presented in a software or hardware manner. When the switch detecting device 300 detects that the power of a certain output terminal 100-104 is turned off, for example, the power of the output terminal 100 is turned off, the scheduling module 202 of the power management device 200 directly skips the output terminal 100 to make the check time. Can be assigned to other in-use outputs 101~104. In other embodiments, the power management device 200 can also cooperate with environmental detection devices, such as a thermometer and hygrometer, a smoke detector, an access control device, etc., to ensure the environment security in the equipment room.

4 is a schematic diagram of another embodiment of a power management device. As shown in FIG. 4, a power management device 200 is disposed in the multi-hole socket 400. The multi-hole socket 400 has a plurality of output terminals 401-403 to provide power. The priority status of each of the output terminals 401 to 403 is sequentially checked by the scheduling module 202 of the power management device 200. Thereby, one power management device 200 can manage the plurality of outputs 401 to 403 to save hardware costs. In other embodiments, the power management device 200 can also be used in conjunction with other hardware devices depending on the room setting requirements.

FIG. 5 is a detailed flow chart of an embodiment of a power management method. As shown in FIG. 5 and FIG. 1, step S1012 is further included: the priority status of each of the output terminals 100-104 is confirmed. After the scheduling module 202 obtains the priority status of each of the output terminals 100-104, the scheduling module 202 then confirms whether the priority status of the output terminals 100-104 needs to be measured. Please refer to FIG. 6 at the same time. Priority status execution program. If the scheduling module 202 confirms that the output terminal 100 is in the first priority state, the output module 100 of the first priority state needs to be measured, so the scheduling module 202 outputs a signal to the measurement module 204, and performs step S1020: The load state of the output terminal 100 in the first priority state is measured, and then step S1022 is performed: comparing the load state with the preset condition, a comparison result C is generated. When the value of the load state is in the range of the preset condition corresponding to the first priority state, the measurement module 204 outputs the comparison result C to the setting unit to maintain the same priority state as before, and then by the storage unit 208. Go to step S1050: store the priority status. Finally, step S1070 is executed: switching to the next output terminal 101. Similarly, if the range of the load condition in the preset condition corresponds to the second priority state or the third priority state, the measurement module 204 outputs the comparison result C to the setting unit 206 to change the priority state.

In addition, in step S1012, if the scheduling module 202 confirms that the priority state of a certain output terminal 100-104 is not the first priority state, then in step 1030d or step 1030e, the scheduling module 202 directly sends a message to the setting. The unit 206 causes the setting unit 206 to advance the priority state of the output terminal other than the first priority state by one step. As shown in FIG. 5, if the scheduling module 202 checks that the priority state of the output terminal 101 is the second priority state, because the output terminal 100 that is not the first priority state does not need to be measured, the scheduling module 202 directly outputs the signal. To the setting unit 206, the priority state of the output terminal 101 of the second priority state is promoted to the first priority state. After the setting unit 206 is set, the storage unit 208 records the priority state of the set output terminal 101, and then switches to the next output terminal 102, and repeats the above steps. Similarly, if the scheduling module 202 checks that the priority state of the output terminal 102 is the third priority state, because the output terminal 102 that is not the first priority state does not need to be measured, the scheduling module 202 directly outputs the signal to the setting unit. 206: Promote the priority state of the output terminal 102 of the third priority state to the second priority state. Then switch to the next output, and so on, repeat the above procedure. In addition, in the flow of FIG. 5, the process of determining whether the output power is turned on or off in conjunction with FIG. 3 is further included. In an embodiment, step S1080 may be initiated by a call interrupt. . In step S1080, the switch detecting device 300 can be used to detect that the power of the output terminal is turned on or off. Once the power of the output terminal is switched from the on state to the off state, step S1090a is performed, and the output of the closed output terminal is not set. If the output is switched from the off state to the on state, the output is preset to have a preset priority state in step S1090a. This embodiment is the first priority state, but is not limited thereto. . It should be noted that although FIG. 5 starts S1080 by using an interrupt to determine whether the power is turned on, it is not limited thereto. For example, S1080 may be started after any step of S1010 to S1070.

Table 1 and Table 2-3 show the comparison of different implementation modes, wherein Table 1 represents the conventional polling mode, and Table 2-3 represents the measurement method using the present invention.

Table 1 shows the number of queries required for each output for each inquiry in the conventional mode. The measurement module 204 measures the load state of the 12 output terminals one by one in each polling. Therefore, regardless of the preset load state of each output terminal, the measurement module 204 is in each polling time. The 12 outputs will measure their load status one by one. In the right field, the test time is set to 2000 seconds, and the measurement time of each output is 2.5 seconds, so the total number of first polls can be calculated as 800 times. Since there are 12 outputs, a total of 12 rounds are polled. At this time, the 12 outputs are all the same setting, that is, the importance of each output is equal, so each output has the same weight of 8.33%. Each output can be assigned approximately 66 times (800 times the weight) during the test time, which is equivalent to 166 seconds.

The embodiment of Table 2-3, in order to obtain the result obtained by the measurement inspection method of the present invention, at the beginning, as shown in Table 2, the priority state of each output is set to the highest, so that each output is first Check it once in the process of Figure 5. Thereafter, as shown in Table 3, in the left field, the first, sixth, and twelfth output currents are greater than 1 amp, so the priority state of the three outputs is maintained at the first priority state. The currents at the second and tenth outputs are between 0 and 1 amp, so the priority status of the two outputs is reset to the second priority. Similarly, the fourth, seventh and eighth outputs are reset to the third priority state. In addition, the third, fifth, ninth and eleventh output terminals are detected that the power is turned off, so the priority state is not set. When checking, the scheduling module 202 skips the output terminal without setting the priority state, save time. The above detection method can be detected by using the switch detecting device 300 (as shown in FIG. 3).

In the right side field of Table 3, the output end of the first priority state is occupied 6 times, the output end of the second priority state is occupied 3 times, and the output end of the third priority state is occupied 2 times. The power is turned off, that is, the output with no priority setting is set to 0 times. It should be noted that, in the present embodiment, the so-called check one circle refers to the case where the priority state of each output terminal is once again returned to the first priority state according to the adjustment of the priority state in the flow of FIG. Therefore, if in the above state, for the present embodiment, after one round of inspection, the total cumulative number of times detected by each output terminal is 30 (the number of times of checking one turn = the number of times set X corresponds to the number of output terminals, That is, 6x3+3x2+2x3=30). At the same time, the corresponding weight can be calculated, for example, the weight of the first output is 20% (weight = set number of times / number of times to check one circle). Within 2000 seconds of the test time, the total number of checks is 800, and the number of times allocated to each output is: 800 X weight. For example, the number of inspections at the first output is 160, and the number of inspections at the second output is 80. By means of the weight setting, the test time can be further allocated to the output with higher priority, so that the output with higher priority gets more inspection times. Comparing the total number of outputs of Table 1 and Table 3, it can be known that after the weight is set, the benefit of each output changes (benefit = new number / original number), such as the number of times of the first output is increased by 140%, while the second output is The number has increased by 20%. On the other hand, because the third, fifth, ninth, and eleventh output power supplies are off, one-third (33.33%) of the outputs do not have to be checked. It must be noted that the length of the test time is adjustable, and the range of the preset condition range can also be adjusted according to requirements. In addition, the number of the range ranges is not limited to three, that is, the priority status is not limited to three. The above setting times and weights can also be adjusted according to requirements. For example, after the test time is over, the number of times each output end is checked to calculate a new weight.

After the second check is completed, the setting module 206 resets the priority state according to the comparison result C of the previous check, and the priority state of the output end of the non-first priority state is raised one level forward. As shown in Table 3, the second output is in the second priority state during the second inspection, and in the third inspection, the scheduling module 202 raises the priority state of the second output to the first priority state. Therefore, at the third inspection, the measurement module 204 will measure the second output. In addition, the arrangement of the output terminals can also be arranged according to the power consumption amount for convenient setting. In summary, by adjusting the time of the output and the number of checks, the important output can be allocated more resources to improve the security of the equipment room.

The present invention has been described by the above-described related embodiments, but the above embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the invention.
