Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a control method, a device and equipment for BBU battery electric energy metering, which reduce the electric energy consumption and avoid unnecessary resource waste when an electric energy metering chip monitors and meters the electric quantity of a BBU standby battery.
Referring to fig. 1, fig. 1 is a schematic flow chart of a control method for BBU battery electric energy metering, which is disclosed in the embodiment of the present invention, and the method includes:
s101, acquiring target information of an electric energy metering chip in the BBU battery.
Specifically, in this embodiment, the target information of the electric energy metering chip includes a current operating mode of the electric energy metering chip, current electric quantity information of the electric energy metering chip, a discharge current of the BBU battery cell metered by the electric energy metering chip, and the like.
As an optional embodiment, the target information includes electric quantity information of the electric energy metering chip and a current operating mode of the electric energy metering chip. After the target information of the electric energy metering chip is determined, a target operation mode (namely an operation mode to be switched) of the electric energy metering chip can be determined according to the target information, after the target operation mode is determined, a control instruction can be sent to the electric energy metering chip so as to trigger a target register (the mode in the target register corresponds to the target operation mode) corresponding to the target operation mode in the electric energy metering chip by using the control instruction, the register of the electric energy metering chip can be preset through software programming in the electric energy metering chip, each operation mode of the electric energy metering chip is configured in each register through a program, and the operation mode of the electric energy metering chip comprises a working mode, a sleep mode and a shutdown mode. Correspondingly, the sent control instruction also comprises a target operation mode corresponding to the electric energy metering chip, after the electric energy metering chip receives the control instruction, the register in the electric energy metering chip is triggered by the control instruction, and then the electric energy metering chip operates in the operation mode registered in the target register after being triggered by the control instruction. In addition, the first control instruction may be sent to the electric energy metering chip by the external controller through an I2C bus.
As an optional embodiment of the present invention, the step S101 includes, for an acquisition cycle of acquiring target information of an electric energy measurement chip in the BBU battery, acquiring the target information with a certain time period as a time cycle:
and acquiring target information of the electric energy metering chip in the BBU battery by taking the preset time as a period.
Specifically, in this embodiment, the length of the predetermined time may be determined according to an actual situation, and in this preferred embodiment, acquiring the target information with the predetermined time as a cycle means switching the operation modes of the electric energy metering chip with the predetermined cycle, and correspondingly, the duration of each operation mode of the electric energy metering chip is also the same predetermined time, and of course, according to an actual situation, the time intervals between the electric energy metering chips in the BBU battery may also be acquired differently (that is, the duration of each operation mode of the electric energy metering chip is different predetermined times).
Assuming that the mode included in the first control instruction sent in the first time period is the working mode, the mode included in the first control instruction sent in the second time period is the sleep mode, and the mode included in the first control instruction sent in the third time period is the shutdown mode. Of course, the pattern contained in the first control instruction transmitted for three time periods is not limited to the above-mentioned order. In addition, the first control commands of the first time period and the second time period may have the same mode, and the first control commands of the second time period and the third time period may have different modes, for example, the mode included in the first control command of the first time period and the second time period is the sleep mode, and the mode included in the first control command of the third time period is the power-off mode.
And S102, determining a target operation mode of the electric energy metering chip according to the target information.
Specifically, in this embodiment, the target information includes electric quantity information and a current operating mode of the electric energy metering chip, and the following two conditions may be provided for determining the target operating mode of the electric energy metering chip according to the target information: the first method is to determine a target operation mode of the electric energy metering chip according to the current operation mode of the electric energy metering chip, wherein the target operation mode is different from the current operation mode of the electric energy metering chip. And secondly, determining a target operation mode of the electric energy metering chip according to the current operation mode of the electric energy metering chip and the electric quantity of the electric energy metering chip. The electric quantity of electric energy measurement chip measurement is the electric quantity of electric core, and when the electric quantity of electric core was more, the electric energy measurement chip can not continuously measure the electric current of electric core, but when the electric quantity of electric core was less, need continuously measure the electric quantity of electric core, and the condition that relevant personnel can not know when avoiding electric core electric quantity to exhaust takes place.
Therefore, as an alternative embodiment of the present invention, step S102 includes:
judging whether the current operation mode is a working mode or not;
if the power supply is in the working mode, judging whether the power information is the target power;
if the target electric quantity is the target electric quantity, switching the current working mode into a sleep mode or a power-off mode;
if the target electric quantity is not the target electric quantity, the working mode is kept;
and if the current operation mode is not the working mode, switching the current working mode into the working mode.
Specifically, in this embodiment, the target electric quantity is identification information that the battery core has sufficient electric quantity, and the target electric quantity is specifically how much suitable, which may be determined according to the model of the battery core. When the electric quantity of the electric core metered by the electric energy metering chip is sufficient, the electric energy metering chip does not need to meter the electric quantity of the electric core in real time, and at the moment, the electric energy metering chip is set to be in a sleep mode or a shutdown mode. When the electric core has insufficient electric quantity, the electric quantity of the electric core needs to be continuously measured by the electric quantity measuring chip (namely, the electric quantity measuring chip is in a working mode), and if the current mode of the electric energy measuring chip is a sleep mode or a shutdown mode, the sleep mode or the shutdown mode needs to be switched to the working mode, so that the electric quantity of the electric core of the electric energy measuring chip is measured.
In addition, it should be noted that when the electric quantity of the battery cell measured by the electric energy measuring chip is sufficient, the electric energy measuring chip can be alternately switched among the three modes, that is, the operating modes of the electric energy measuring chip after three times of switching are different. At present, when the factor that the electric quantity of the electric core metered by the electric energy metering chip is sufficient is not considered, the operation modes of the electric energy metering chip after the electric energy metering chip is switched for three times can be different.
S103, triggering a target register corresponding to the target operation mode to control the electric energy metering chip to be switched from the current operation mode to the target operation mode; the running mode of the electric energy metering chip comprises a working mode, a sleep mode or a shutdown mode.
Registers of the electric energy metering chip can be set in the electric energy metering chip in advance through software programming, each register is configured with each operation mode of the electric energy metering chip through programs, and the operation modes of the electric energy metering chip comprise a working mode, a sleep mode and a shutdown mode.
Specifically, in this embodiment, after the register of the electric energy metering chip includes the control instruction of the target operation mode, the electric energy metering chip operates in the operation mode corresponding to the target register. The following describes each operation mode of the electric energy metering chip in the embodiment of the present invention in detail.
As an optional embodiment of the present invention, if the target operation mode is the working mode, the electric energy metering chip updates the electric energy metering data of the BBU battery at a first preset time;
if the target operation mode is the sleep mode, the electric energy metering chip updates the electric energy metering data of the BBU battery at a second preset time;
and the second preset time is greater than the first preset time.
And if the target operation mode is the shutdown mode, stopping the operation of the electric energy metering chip.
And the electric energy metering chip updates the electric energy metering data of the BBU battery at a first preset time.
Specifically, in the preferred embodiment, the electric energy metering chip updates the electric energy metering data of the BBU battery at the first preset time as the electric energy metering chip reads the electric quantity of the electric core of the BBU battery at the first preset time as a cycle, wherein for the first preset time, the preferred embodiment of the present invention is 1 second, and for the electric energy metering chip in the operating mode, the power consumption when the electric energy metering chip updates the electric energy metering data of the BBU battery at the first preset time is 500 uA.
And if the operation mode is the sleep mode, the electric energy metering chip updates the electric energy metering data of the BBU battery at a second preset time.
And the second preset time is greater than the first preset time.
Specifically, in this preferred embodiment, the electric energy metering chip updates the electric energy metering data of the BBU battery at the second preset time as the electric energy metering chip reads the electric quantity of the electric core of the BBU battery at the second preset time as a cycle, where the second preset time is preferably 5 seconds in the embodiment of the present invention, and for the electric energy metering chip in the sleep mode, the power consumption when the electric energy metering chip updates the electric energy metering data of the BBU battery at the second preset time is 110 uA. After the time interval for updating data of the electric energy metering chip in the sleep mode is prolonged, the electric quantity of the electric core of the BBU battery is not required to be frequently read, and the power consumption of the corresponding electric energy metering chip is correspondingly reduced. The specific size of the first preset time and the second preset time may be determined according to actual situations, and the embodiment of the present invention is not limited herein.
And if the operation mode is the shutdown mode, stopping the operation of the electric energy metering chip.
Specifically, in this embodiment, after the register of the shutdown mode of the electric energy metering chip is triggered, the electric energy metering chip is in the shutdown mode, and at this time, the electric energy metering chip does not consume the electric quantity of the electric core of the BBU battery any more, that is, the electric core is disconnected from the BBU battery.
It should be noted that, for the working mode and the sleep mode of the electric energy metering chip, the electric energy consumed by the electric energy metering chip during operation may be the same, except that the period of updating the electric energy metering data by the electric energy metering chip in the working mode is shorter than the period of updating the electric energy metering data by the electric energy metering chip in the sleep mode, so that the total energy consumption of the electric energy metering chip in the working mode is higher than that of the electric energy metering chip in the sleep mode. Because the electric energy metering chip in the shutdown mode does not consume energy, the total energy consumption of the electric energy metering chip in the shutdown mode is lower than that of the electric energy metering chip in the working mode and the sleep mode. Compared with the prior art that the electric energy metering chip is continuously in the working mode in the same time period, the method greatly reduces the energy consumption. In addition, in the embodiment of the present invention, in the same time period, compared with the case that the electric energy metering chip in the prior art is continuously in the working mode, the electric energy metering chip in the embodiment of the present invention operates in three operation modes within a certain time period, and the sending period of the first control instruction corresponding to the three operation modes is subject to the actual requirement.
Therefore, the control method for measuring the electric energy of the BBU battery disclosed in the embodiment of the present invention can determine the target operation mode of the electric energy chip through the obtained target information of the electric energy measurement chip in the BBU battery, and can trigger the target register corresponding to the target operation mode, so that the electric energy measurement chip can be switched from the current operation mode to the target operation mode, wherein the operation mode of the electric energy measurement chip includes a working mode, a sleep mode or a shutdown mode. Therefore, by adopting the scheme, the electric energy metering chip can be controlled to be switched among three different modes, namely the electric energy metering chip is ensured to run in a working mode or a sleep mode or a shutdown mode, the electric energy metering chip is prevented from being continuously in the working mode, the electric energy consumption is reduced, and unnecessary resource waste is avoided.
In addition, considering that the period of reading the current of the electric core in the BBU battery by the electric energy metering chip in the sleep mode is longer, the voltage value provided by the electric core in the BBU battery to the electric energy metering chip can be adjusted, so as to further reduce the energy consumption of the electric energy metering chip. Therefore, based on the above embodiments, as an alternative embodiment of the present invention, the method further includes:
and controlling the voltage value provided by the charging control module in the BBU battery for the electric energy metering chip.
Specifically, in this embodiment, the electric energy metering chip is connected to the electric core of the BBU battery through a charge-discharge control module (which may be a charge-discharge control circuit). In addition, when the electric energy metering chip updates the electric energy metering data, the charging and discharging control module can be controlled to adjust the voltage/current provided for the electric energy metering chip by sending a control instruction.
In view of the large difference between the energy consumption of the electric energy metering chip in the working mode and the energy consumption of the electric energy metering chip in the sleep mode, based on the above embodiment, as an optional embodiment, the controlling the charging control module to provide the voltage value for the electric energy metering chip includes:
the control charging control module is used for providing a voltage value corresponding to the current operation mode of the electric energy metering chip for the electric energy metering chip;
controlling the charging control module to provide a voltage value for the electric energy metering chip to be a voltage value corresponding to the current operation mode of the electric energy metering chip;
if the electric energy metering chip is in a working mode, controlling the charging control module to provide a first voltage value for the electric energy metering chip;
if the electric energy metering chip is in the sleep mode, controlling the charging control module to provide a second voltage value for the electric energy metering chip;
if the electric energy metering chip is in a shutdown mode, controlling the charging control module to provide a third voltage value for the electric energy metering chip;
the first voltage value is greater than the second voltage value, and the second voltage value is greater than the third voltage value.
Specifically, in the present embodiment, the first voltage value in the present preferred embodiment is preferably greater than the second voltage value. When the electric energy metering chip updates the electric energy metering data, the charging and discharging control module can be controlled to provide the voltage/current value when the electric energy metering chip updates the electric energy metering data. For example, when the electric energy metering chip is in the sleep mode, the charge-discharge control module is controlled to provide the second voltage value corresponding to the sleep mode, and when the electric energy metering chip in the sleep mode updates the electric energy metering data, the charge-discharge control module is controlled to provide the voltage/current required by the electric energy metering chip to update the electric energy metering data. The first voltage value, the second voltage value, and the specific magnitude of the voltage/current required by the electric energy metering chip to update the electric energy metering data may be determined according to actual conditions, and the embodiment of the present invention is not limited herein.
