Referring to fig. 2, fig. 2 is a block diagram of the metering platform 100 in fig. 1. The metrology platform 100 in the embodiments of the present invention may be, but is not limited to, a computer, a computing device, etc. The metrology platform 100 comprises: memory 110, memory controller 120, and processor 130.

It will be appreciated that the configuration shown in FIG. 2 is merely illustrative and that metrology platform 100 may also include more or fewer components than shown in FIG. 2 or have a different configuration than shown in FIG. 2. The components shown in fig. 2 may be implemented in hardware, software, or a combination thereof.
Referring to fig. 3, fig. 3 is a flowchart illustrating a low power consumption control method according to an embodiment of the invention. The method is applied to the metrology platform 100. The specific flow of the low power consumption control method is described in detail below.
Step S110, determine that the current time is in the working period or the sleep period.
In this embodiment, the metering platform 100 stores a preset working period and a preset sleep period. The proportion of the sleep time corresponding to the sleep period to the total time is greater than the proportion of the working time corresponding to the working period to the total time. Therefore, whether the time belongs to the working period or the sleep period can be judged according to the current time and the preset working period and sleep period. For example, taking a day as an example, that is, the total time is 24 hours, 8 to 10 points of a certain day are preset as a working period, and the remaining time is a sleep period. If the current time is 11 o' clock of the day, it can be determined that the current time is in the sleep cycle. If the current time is 9 o' clock of the day, it can be determined that the current time is in the duty cycle.
Step S120, when the current time is in the sleep cycle, entering into the sleep mode.
In this embodiment, if the current time corresponds to the sleep cycle, the metering platform 100 may turn off all the peripheral devices, the clock source, the power domain, and the like, and directly enter the sleep mode. That is, during the sleep period, the metrology platform 100 is inactive. Thereby greatly reducing power consumption as compared to having metrology platform 100 in an operational mode at all times. The peripheral devices include internal devices in the metering platform 100, and a metering device 200 and a communication device 300 connected to the metering platform 100. Internal devices within the metering platform 100 may include, but are not limited to, GPIO ports, serial ports, and the like.
Step S130, when the current time is in the working cycle, the working mode or the sleep mode is entered according to the working state of the peripheral.
In this embodiment, the metering platform 100 stores a power consumption management linked list, where the power consumption management linked list may include a plurality of peripheral identifiers, and a working state, a clock domain, and a power domain corresponding to each peripheral identifier. The peripheral identification corresponds to the peripheral one to one. The metering platform 100 may further reduce power consumption according to the power consumption management linked list.
Referring to fig. 4, fig. 4 is a flowchart illustrating sub-steps included in step S130 in fig. 3. Step S130 may include sub-step S131 and sub-step S132.
And the substep S131, obtaining the working state of each peripheral according to the power consumption management linked list, and judging whether the working states of all the peripherals are stop working or not.
And a substep S132, when all the peripheral devices stop working, turning off the clock source and the power domain corresponding to the peripheral devices in the power consumption management linked list to enter a sleep mode.
In this embodiment, when the working state of the peripheral device changes, the power consumption management linked list is directly updated correspondingly, so that the working state of each peripheral device can be obtained through the power consumption management linked list. The working state may include stopping working and working.
If the working state of each peripheral in the power consumption management linked list is stop, it indicates that the clock source and the power domain corresponding to the peripheral do not need to be in a normal working state any more, and in this case, the metering platform 100 adjusts the states of the clock source and the power domain corresponding to the peripheral in the power consumption management linked list to be in a closed state, and enters a sleep mode. Therefore, although the current time corresponds to the work cycle, under the condition that the peripheral does not work, the corresponding clock source and the corresponding power domain can be closed, and the power consumption is further reduced by entering the sleep mode.
Referring to fig. 4 again, step S130 may further include sub-step S133 and sub-step S134.
And a substep S133, when the working states of all the peripherals are not stopped, taking the peripheral whose working state is stopped as a target peripheral, and determining whether a target clock source and a target power domain corresponding to the target peripheral are being used by other peripherals whose working states are being operated according to the power consumption management linked list.
And a substep S134, turning off the target clock source and/or the target power domain corresponding to the target peripheral, which is not used by other peripherals whose operating states are working, to enter a low power consumption operating mode.
In this embodiment, if it is determined that the working states of some of the peripherals are working and the working states of some of the peripherals are off (i.e., turned off) according to the power consumption management list, the metering platform 100 may use the peripherals whose working states are off as target peripherals, and further use the clock sources and the power domains corresponding to the target peripherals in the power consumption management list as target clock sources and target power domains. The metering platform 100 determines whether the peripheral devices corresponding to the target clock source and the target power domain are working according to the power consumption management linked list, and determines whether the target clock source and the target power domain corresponding to the target peripheral device are being used by other peripheral devices working in working states according to the obtained determination result.
After the above determination is completed, the metering platform 100 may turn off the target clock source and/or the target power domain corresponding to the target peripheral, which is not used by other peripherals whose operating states are working, to enter a low power consumption operating mode.
For example, the peripheral a and the peripheral B use the same clock source 1, and if the peripheral a using the clock source 1 stops working, it needs to determine whether the peripheral B also using the clock source 1 stops working. If the clock B stops working, which means that the clock source 1 is not used by the peripheral whose working state is working, the clock source 1 may be turned off. If the clock B is working, which means that the clock source 1 is being used by the peripheral whose working state is working, the clock source 1 cannot be turned off.
Optionally, in an implementation manner of this embodiment, the metering platform 100 may be a platform using rassa RL78, and a halt mode and a stop mode of the low power consumption modes are selected. When the peripheral works, the system enters a halt mode (namely a low-power-consumption working mode); when no peripheral works, the system enters into a stop mode (namely a sleep mode).
Referring to fig. 5, fig. 5 is a second flowchart of a low power consumption control method according to an embodiment of the invention. The method may further include step S141 and step S142.
In step S141, when the sleep mode is in the duty cycle and the wake-up signal is received, the sleep mode is switched to the duty mode.
And step S142, after the working mode is switched, judging whether the working mode needs to be switched to the dormant mode again according to the power consumption management linked list.
In this embodiment, if the metrology platform 100 is in the sleep mode during the working period, it is not conducive to normal data communication. Therefore, in this embodiment, when the metrology platform 100 is in the sleep mode in the working cycle, the corresponding mode is switched according to whether the wake-up signal is received. The wake-up signal may be a timer wake-up signal of a sleep mode in a working cycle, or may be a wake-up signal sent by the communication device 300.
After receiving the wake-up signal, the metrology platform 100 switches from the current sleep mode to the working mode. After the measurement platform 100 is switched from the sleep mode in the working period to the working mode in the working period, judging whether a working condition exists according to the power consumption management linked list, namely the measurement platform 100 needs to work, and if so, working is carried out; if not, switching to the sleep mode again.
For example, a timer is set, and the timer is used to send a timer wake-up signal every 2s when the metering platform 100 is in the sleep mode in the working cycle. Therefore, the metering platform 100 wakes up from the sleep mode (i.e. switches to the working mode) every 2s when in the sleep mode of the working cycle, and checks whether data is received or other work is performed within 2 s. If yes, the operation is carried out, and the sleep mode in the working period is entered again after the operation is finished. If not, the sleep mode in the working period can be directly entered again.
Alternatively, if the received wake-up signal is a signal corresponding to a switching period, that is, the duty cycle is switched to a sleep cycle, the metering platform 100 may wake up first after receiving the wake-up signal, and then enter the sleep mode in the sleep cycle.
Referring to fig. 6, fig. 6 is a third schematic flow chart of a low power consumption control method according to an embodiment of the present invention. The method may further include step S150.
Step S150, when the sleep mode is in the working cycle or the sleep mode in the sleep cycle, if the manual wake-up signal is received, the sleep mode is switched to the working mode until the sleep mode is restored to the mode corresponding to the cycle to which the current time belongs in the preset restoration time.
In this embodiment, no matter which sleep mode is in any cycle, as long as the metering platform 100 receives the manual wake-up signal, the current mode is directly switched to the working mode and is maintained until the preset recovery time. After the preset recovery time comes, the metering platform 100 is switched from the working mode to the mode corresponding to the period to which the working mode belongs. For example, after the preset recovery time is reached, if the current time belongs to a working period, the power management linked list is selected to enter a working mode or a sleep mode; if the current time belongs to the sleep cycle, all the peripheral devices, clock sources, power domains and the like are closed, and the sleep mode is entered.
Alternatively, the metering platform 100 may receive the artificial wake-up signal by, but not limited to, detecting the reception of the artificial wake-up signal through a reed pipe, and the like.
For example, the preset recovery time is set to zero, and the metering platform 100 keeps the working mode to the day zero point after receiving the manual wake-up signal. After reaching the zero point of the day, the metering platform 100 enters a working mode or a sleep mode according to a preset working period, a preset sleep period and the power consumption management linked list.
Referring to fig. 6 again, the method may further include step S101.
Step S101, the power consumption management linked list is pre-established, and after an updating request sent by a peripheral is received, the power consumption management linked list is updated.
In this embodiment, the power consumption management linked list is established in advance according to the information of the peripheral device. And after the power consumption management linked list is established, if the working condition of the peripheral equipment changes, the power consumption management linked list can be updated so as to ensure that the information in the power consumption management linked list is consistent with the actual condition.
Optionally, the power consumption management linked list includes flag bits, and each flag bit corresponds to an external device. When any peripheral is opened or closed, the flag bit state of the peripheral is updated, so that the power consumption management linked list is updated.
In this embodiment, the metering platform 100 includes at least one idle GPIO port (General Purpose Input Output). Referring to fig. 6 again, the method may further include step S160.
And step S160, setting the mode of the idle GPIO port to reduce the power consumption of the idle GPIO port.
In this embodiment, the setting of the mode of the idle GPIO port to reduce the power consumption corresponding to the idle GPIO port includes:
setting the mode of an over-hanging GPIO port in the idle GPIO port and/or a GPIO port with an external pull-up condition as a pull-up input according to a circuit diagram corresponding to the idle GPIO port; and/or the presence of a gas in the gas,
and setting the mode of the GPIO port with the pull-down condition in the idle GPIO ports to be input low level according to the circuit diagram corresponding to the idle GPIO ports.
In this embodiment, the idle GPIO ports include floating GPIO ports, externally pulled-up GPIO ports, pull-down (grounded) GPIO ports, and the like. An idle GPIO port may subject the metering platform 100 to excessive current flow out and in, thereby increasing the power consumption of the metering platform 100. Therefore, by setting the mode of the idle GPIO ports according to the circuit diagram corresponding to the idle GPIO ports, the above-described effects can be avoided, thereby further reducing power consumption.
The metering platform 100 is in a sleep mode with extremely low power consumption when in a sleep cycle, and is in a state of being managed by the sleep mode and the working mode together when in a working cycle, so that peripheral equipment, a clock domain and a power domain are all managed, and the current power consumption is fundamentally reduced. Moreover, since the time corresponding to the sleep cycle is longer than the time corresponding to the work cycle, the metering platform 100 is in the sleep mode for a long time, and the use of current is further reduced. In this way, one battery can also take a long time, avoiding the need for the user to change the battery from time to time.
Referring to fig. 7, fig. 7 is a block diagram illustrating a low power consumption control apparatus 400 according to an embodiment of the present invention. The low power consumption control device 400 is applied to the metering platform 100, and a working period and a sleep period are preset in the metering platform 100. The low power consumption control apparatus 400 may include a determining module 410 and a control module 420.
The determining module 410 is configured to determine that the current time is in a working period or a sleep period, where a ratio of sleep time corresponding to the sleep period to total time is greater than a ratio of working time corresponding to the working period to total time.
The control module 420 is configured to enter a sleep mode when the current time is in the sleep period.
The control module 420 is further configured to enter an operating mode or a sleep mode according to an operating state of a peripheral device when the current time is in an operating cycle, where the peripheral device includes an internal device in the metering platform 100, and the metering device 200 and the communication device 300 connected to the metering platform 100.
