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 first embodiment:
in order to solve the technical problem that the remaining battery capacity of an automatic external defibrillation device cannot be accurately calculated in the prior art, the present embodiment provides a remaining battery capacity calculation method, which can be applied to an automatic external defibrillation device, and as shown in fig. 1, is a schematic flow diagram of the remaining battery capacity calculation method provided in the present embodiment, and the remaining battery capacity calculation method provided in the present embodiment includes the following steps:
Specifically, the memory unit of this embodiment may be an Electrically Erasable Programmable Read Only Memory (EEPROM), and the capacity of the memory unit may be 128 bytes. In this embodiment, the battery information is recorded in the storage unit associated with the battery, so that the battery and the device can be independent, and the battery information of each battery can follow the battery itself, and the current key parameters such as the power consumption of the battery can be known only by reading the battery information on the storage unit. It should also be noted that the present embodiment records battery critical information on the battery, enabling the AED to be used with batteries of different capabilities without requiring adjustment of the AED program code during subsequent battery replacement.
In an optional implementation manner of this embodiment, the storage unit includes: a read-only area and a read-write area; correspondingly, the acquiring basic information and the battery use information of the battery from the storage unit electrically connected with the battery of the automatic external defibrillation device comprises the following steps: and acquiring basic information of the battery from the read-only area, and acquiring the use information of the battery from the read-write area.
Specifically, in this embodiment, the storage unit is divided into a read-only area and a read-write area, and then the battery basic information and the battery usage information are stored in the storage unit in a partitioned manner. The battery basic information may include: the AED equipment can determine the basic information of the battery and adjust the use parameters of the equipment by reading the values of the battery type, the factory time, the expiration time, the total electric quantity value, the low electric quantity threshold value, the second-stage rapid loss proportion, the low electric quantity voltage threshold value and the like; the battery usage information may include: the charging count, the awakening count, the power consumption of the battery, the starting time and the shutdown time can be accurately calculated whether the residual electric quantity of the battery can meet the emergency use of the AED equipment or not by reading and calculating the values.
Further, in an optional implementation manner of this embodiment, the read-only area includes two read-only sub-areas where the basic information of the battery is repeatedly recorded; correspondingly, acquiring the basic information of the battery from the read-only area comprises the following steps: acquiring basic battery information from one read-only subregion, and performing cyclic redundancy check on the basic battery information; when the cyclic redundancy check fails, the basic battery information is acquired from another read-only subarea.
Specifically, in order to reduce the risk of information loss, the present embodiment repeatedly records the battery basic information on two addresses of the read-only area, so that the same information stored on address 2 can be read when the CRC check of the information on address 1 fails.
Further, in an optional implementation manner of this embodiment, the read-write area includes three read-write sub-areas that read and write the battery usage information including the battery power consumption in turn; correspondingly, acquiring the battery use information from the read-write area comprises the following steps: reading the battery power consumption stored in all the read-write subregions, and comparing the battery power consumption; and calling the battery power consumption with the largest value, and recording the number N of the correspondingly stored read-write sub-region, wherein the value of N is more than or equal to 1 and less than or equal to 3.
Specifically, the read-write area of the embodiment has three addresses for reading and writing the battery use information in turn, so that the closer primary battery use information can be ensured to be reserved under the extreme condition, and the influence of information loss and repeated erasing on the service life of the storage unit under the extreme condition is reduced. In addition, after the total power consumption of the battery is calculated based on the battery usage information, the total power consumption of the battery is written into the read-write sub-area with the number of N +1 modulo 3. It should be noted that, in this embodiment, when the battery power consumption is read, the battery power consumption stored in all the addresses may be read, and then the battery power consumption with the largest value is called, but in other embodiments, an address where the battery power consumption has been written last time may be determined, and then the battery power consumption stored in the address is directionally read to call.
And 102, calculating the total power consumption of the battery based on the battery use information.
Specifically, the embodiment adopts the power consumption to calculate the power consumption of the device at every moment when the device is used, and the calculation precision is improved to the millisecond level. It should be noted that, in the present embodiment, the total battery power consumption may be calculated mainly by using the current power consumption, and may be calculated by using the voltage and/or the standby average current, so as to further improve the accuracy of the calculation of the total battery power consumption.
In an optional implementation manner of this embodiment, a set of current values is collected every unit time interval, and a product of the current value and the unit time interval is written into the read-write area as the power consumption of the battery.
Specifically, the present embodiment may adopt a timing task with a unit time length of, for example, 20 milliseconds, and read the present current through the reading circuit, and then multiply the present current by the time of 20 milliseconds, which is the current consumption of the device within 20 milliseconds. And accumulating the current power consumption in the unit time length, putting the accumulated current power consumption into a buffer area variable C, and waiting for next updating or calling. In addition, in combination with this embodiment, the read/write area may include three read/write sub-areas for reading and writing the battery usage information including the battery power consumption in turn, and a timing task may be set to read the power consumption of the buffer variable C for, for example, 60 seconds, to update the remaining power T of the device, where T is T + C, and clear the buffer C, and then write the latest total power consumption T into the EEPROM according to the new address number N is (N +1) Mod 3, so that the write operation is performed cyclically among the three addresses.
In an optional implementation manner of this embodiment, calculating the total power consumption of the battery based on the battery usage information includes: calculating standby time and power-on time based on the power-on time and the power-off time, and calculating the standby power consumption of the equipment based on the standby time; calculating the running power consumption of the equipment based on the starting time; and determining the total power consumption of the battery based on the standby power consumption of the equipment and the running power consumption of the equipment.
Specifically, in this embodiment, the formula for calculating the standby time of the device may be represented as: the standby time length is the time of starting up the computer this time-the time of shutting down the computer last time, and the time length of starting up the computer this time-the time of shutting down the computer this time; further, the calculation formula of the standby power consumption of the device can be expressed as: the device standby power consumption is equal to the standby duration and the device standby average power consumption. And when the computing device is running power consumption, the calculation formula can be expressed as: the device operation power consumption is the boot time length and the device operation average power consumption. And finally, calculating a formula based on the total power consumption of the battery: and obtaining the total power consumption of the battery, namely the running power consumption of the device plus the standby power consumption of the device, adding the total power consumption of the battery to the accumulated power consumption read from the read-write area, and writing the accumulated power consumption into the next EEPROM address.
It should be noted that the AED device may begin entering the low battery pre-alarm mode when the total battery power consumption reaches the low battery threshold. Or after the AED is started, the battery voltage enters a stable state, and when the battery voltage is lower than the low-power voltage threshold value, the AED enters a low-power early warning mode. Or when the number of awakening counts or the number of charging counts reaches a corresponding threshold value, the AED also enters a low-battery early warning mode.
And 103, calculating the residual electric quantity of the battery by combining the total electric quantity consumed by the battery and the basic information of the battery.
Specifically, the present embodiment calculates the remaining battery capacity by combining the total battery power consumption and the battery basic information, significantly improves the accuracy of the remaining battery capacity calculation, and can provide an effective reference for the device usage. In practical applications, the remaining battery capacity may be expressed in percentage.
In an optional implementation manner of this embodiment, when the remaining battery capacity is calculated by combining the total battery power consumption and the basic battery information, first, a boundary value between the first stage and the second stage of the total battery power consumption is calculated based on the total power value and a low power threshold, where the boundary value is the total power value — the low power threshold.
Then, on one hand, when the total power consumption of the battery is smaller than the boundary value, calculating the percentage of the remaining power of the battery according to a first remaining power calculation formula; wherein the first remaining power calculation formula is represented as: t ═ ((totalhigvvalue-P) × 100)/totalhigvvalue;
on the other hand, when the total power consumption of the battery is greater than the boundary value, the percentage of the remaining power of the battery is calculated according to a second remaining power calculation formula; wherein the second remaining power calculation formula is represented as: t ═ T ((TotalLowValue- (P-highPowerValue) × LowPowerHighCost) × 100)/TotalHighValue.
It should be noted that, in this embodiment, T represents the percentage of the remaining battery capacity, P represents the total battery consumption, highPowerValue represents the boundary value between the first stage and the second stage of the total battery consumption, TotalHighValue represents the total capacity value, TotalLowValue represents the low capacity threshold, and lowpowerhighvalue represents the proportion of the rapid loss in the second stage, and this proportion value is the inherent characteristic of the battery, for example, 1.5.
In particular, in the present embodiment, considering that the battery consumption rate is relatively fast when the battery capacity is low, for example, the battery can theoretically last for 100 hours, if the remaining capacity is only 10%, the battery is not able to support 10 hours of use, and based on this, the present embodiment uses a piecewise function form to calculate the remaining capacity of the battery, assuming a total battery capacity of 3000mAh, for example, the first-stage battery capacity may be set to 2500mAh, and the capacity of the second stage battery is set to 500mAh, when the total power consumption of the battery is between 0 and 2500mAh, the remaining battery capacity is more than 500mAh, the remaining battery capacity is calculated by adopting a first remaining battery capacity calculation formula, and when the total power consumption of the battery is between 2500-.
