The storage battery is a main power supply part of the automobile, and not only provides starting current for the engine, but also supplies power for electronic equipment of the whole automobile. With the increasing variety of vehicle-mounted electronic devices, such as vehicle-mounted GPS terminals, vehicle-mounted electronic dogs, reversing radars, automobile data recorders, vehicle navigation systems, and the like, these vehicle-mounted electronic devices generally do not have independent power supplies, but directly use vehicle storage batteries as power supplies, resulting in the increasing of the power supply pressure of the vehicle storage batteries, and therefore, higher requirements are put forward for the design of various vehicle-mounted electronic device power supply systems. Taking a vehicle-mounted GPS terminal as an example, the vehicle-mounted GPS terminal in the current market has increasingly powerful functions, particularly, after integrating functions such as entrance guard, monitoring and the like, the vehicle-mounted GPS terminal is objectively required to be in a working state for 24 hours, and the functions of some vehicle-mounted terminals, such as collision detection, flameout recording and the like, are required to be still in a working state after the vehicle is flameout, if the vehicle stops for a period of time, a vehicle storage battery often can cause the vehicle to be incapable of being started by normal ignition due to continuous power consumption, and even the storage battery is exhausted and permanently damaged.
In the prior art, a constant low-voltage protection threshold is generally set, which is generally between 10.5V and 11.3V, the vehicle-mounted electronic device continuously monitors the voltage of the vehicle battery through an ADC (analog to digital converter), which can convert an analog signal into a digital signal, specifically, convert the voltage into a digital signal and obtain an input voltage value by settling the digital signal), and when the voltage of the battery is detected to be lower than the low-voltage protection threshold, all flameout holding functions are stopped, so that the vehicle-mounted electronic device is completely powered off, and a power consumption circuit of the vehicle-mounted electronic device is less than 1mA, thereby avoiding continuous power consumption caused by the vehicle-mounted electronic device.
However, with the low voltage protection method in the prior art, there are several problems:

1) for vehicles with poor battery states, the low-voltage protection value is low, and the risk of battery power shortage exists;

It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
A first aspect of the present disclosure provides a low voltage protection method for an onboard electronic device, the method is to dynamically set a low voltage protection value for a specified date for the onboard electronic device to protect the onboard electronic device of a vehicle to the maximum extent and prolong the service life of a battery of the vehicle, as shown in fig. 1, and the method includes:
in step S1, an initial low voltage protection value is set.
Specifically, in step S1, an initial low-voltage protection value having universality is set as an initial value for different onboard electronic devices mounted on the vehicle, and the low-voltage protection value is applicable to different vehicles and different types of onboard electronic devices as much as possible, particularly to onboard electronic devices mounted after the vehicle. A relatively high protection value for the low voltage, for example between 11.3V and 11.8V, for example 11.5V, can usually be set. Of course, this initial low pressure protection value may be adjusted as desired.
And step S2, collecting storage battery voltage sampling data from the Nth day to the Mth crown block after flameout at preset sampling frequency and preset time intervals, wherein N is more than or equal to 1, and M is more than N.
In the step, the low-voltage protection value for the vehicle-mounted electronic equipment can be dynamically determined according to the change of the battery voltage data in order to obtain the battery voltage sampling data after the vehicle is flamed out every time. The method comprises the steps of taking the date that a vehicle stalls at any time as a starting point, and sequentially collecting storage battery voltage sampling data after the vehicle stalls in the time period from the Nth day to the Mth day after the date by using a preset collecting frequency and a preset time interval, wherein N is more than or equal to 1, and M is more than N.
It should be noted that the preset sampling frequency may be determined according to actual sampling requirements, precision requirements of the sampled data, performance of the data acquisition device, and other factors, if the preset sampling frequency for sampling is too large, the precision of subsequent data calculation may be low, and if the preset sampling frequency for performing sampling is too small, the amount of the acquired data may be too large, and the workload of subsequent data calculation may be too large. For example, the storage battery voltage data can be sampled for 1 time every minute, namely the storage battery voltage sampling data after the vehicle is flamed out is collected every 1 minute, so that the calculation accuracy and the calculation efficiency of the sampling data can be considered.
It should be noted that the preset time interval can be determined according to actual sampling requirements, and the preset time interval can be reasonably determined according to the required low-voltage protection value of the specified date. For example, to obtain the under-voltage protection value on the 10 th day after the vehicle is turned off for the first time, the preset time interval here may be set to 7 days, 0: and collecting battery voltage sampling data of preset time, such as 10 minutes, after each vehicle is shut off in a 24:00 time period from the 00 th day to the 7 th day. Of course, the preset time interval can be adjusted at any time according to needs.
And step S3, taking a weighted average value of all or part of the battery voltage sampling data from the Nth day to the Mth day after the crown block vehicle is flamed out as a low-voltage protection value of the M +1 th day.
In the step S3, for the acquired nth day 0: 00 to day M24: 00 sampling data of all battery jar voltages after the vehicle is flamed out can adopt all sampling data or select effective partial sampling data, so as to take weighted average value of all sampling data or partial sampling data as the low-voltage protection value of the M +1 th day. For example, when the preset time interval is set to 7 days, on the 1 st day 0 after the first vehicle key-off: and in a 24:00 time period from the 00 th day to the 7 th day, collecting all battery voltage sampling data of preset time, such as 10 minutes, after the vehicle is shut off every time, and taking a weighted average value of all sampling data of the 7 th day time period as a low-voltage protection value of the 8 th day.
Here, for convenience of calculation, all the sampled data may be selected to perform weighted averaging, and of course, all the obtained battery voltage sampled data may be primarily screened, for example, considering that there may be a certain fluctuation or error in the head and tail data in the battery voltage sampled data, the battery voltage sampled data at the head and tail may be rejected, so as to ensure the accuracy of subsequent data calculation. Therefore, in step S3, the battery voltage sampling data from the nth day to the mth day after the crown block is turned off for a predetermined time, for example, 10 minutes, may be sorted to form a sampling data sequence, the battery voltage sampling data at both ends of the sampling data sequence are filtered, the remaining battery voltage sampling data is weighted-averaged, for example, all the sampling data are sorted according to size, and 5% data of the head and 5% data of the tail are filtered, where the filtering operation is to filter out high-voltage and low-voltage glitches data generated by battery fluctuation, and the middle 90% of the sampling data is retained to be weighted-averaged, so as to improve the accuracy and precision of the obtained low-voltage protection value.
Step S4, setting N to N +1 and M to M +1, and repeatedly executing steps S2 to S3 until M +1 equals the specified date to acquire the low voltage protection value of the specified date.
In the step S4, since the preset time interval for performing the sampling is not changed, the starting and ending times of the sampling time period are pushed back by one day in each sampling process, that is, N +1 and M +1 are set, and then steps S2 to S3 are repeatedly performed until the date represented by M +1 is equal to the specified date, so that the low voltage protection value of the specified date can be acquired.
According to the above-mentioned embodiment, the preset time interval is set to 7 days, that is, M is equal to N +6, so that the battery voltage sampling data after the vehicle is flamed off for 7 continuous days can be collected. When N is 1, M is 7, in this case, in step S2, the battery voltage sampling data may be collected from the 1 st day to the 7 th day after the vehicle is turned off for the first time, and in step S3, for the collected 1 st day 0: 00 to day 7 24:00 taking the weighted average of all or part of the battery voltage sampling data after the vehicle is flamed out as the low-voltage protection value on the 8 th day. By repeatedly executing the above steps S2 to S3 in step S4, the acquisition of day 20 is continued: the battery cell voltage sampling data collected in the period of 24:00 on the 8 th day is 24: and when the date is 00, obtaining the low-voltage protection value of the day 9, and so on until the low-voltage protection value of the day on the appointed date is obtained through the storage battery voltage sampling data 7 days before the appointed date.
According to the vehicle-mounted electronic equipment low-voltage protection method provided by the disclosure, the low-voltage protection value of the vehicle storage battery can be dynamically adjusted according to the collected storage battery voltage sampling data after the vehicle is flamed out for a period of time, so that even for vehicle storage batteries of different brands and different styles, and even if the vehicle storage batteries are at different temperature conditions and different old and new degrees, the low-voltage protection of the vehicle storage battery can be stably carried out, the partial functions of the vehicle-mounted electronic equipment are effectively prevented from being prematurely turned off due to continuous power consumption of the vehicle-mounted electronic equipment and high low-voltage protection value caused by low-voltage protection value, and the service life of the vehicle storage battery is effectively prolonged under the condition that the functions of the vehicle-mounted electronic equipment are not influenced.
A second aspect of the present disclosure provides a low voltage protection device for an onboard electronic device, which is to dynamically set a low voltage protection value for a specified date for the onboard electronic device to protect the onboard electronic device of a vehicle to the maximum extent and prolong the service life of an onboard battery, as shown in fig. 2, and includes: a setting module 10, a sampling module 20, a determining module 30 and an obtaining module 40, which are coupled to each other, wherein,
a setting module 10 for setting an initial low voltage protection value.
Specifically, the setting module 10 can set a universal initial low-voltage protection value as an initial value for different on-board electronic devices mounted on a vehicle, where the low-voltage protection value is applicable to different vehicles and different types of on-board electronic devices as much as possible, and is particularly applicable to on-board electronic devices mounted on vehicles later. A relatively high protection value for the low voltage, for example between 11.3V and 11.8V, for example 11.5V, can usually be set. Of course, this initial low pressure protection value may be adjusted as desired.
And the sampling module 20 is used for collecting the battery voltage sampling data from the Nth day to the Mth day after the crown block vehicle is flamed out at a preset sampling frequency and a preset time interval, wherein N is more than or equal to 1, and M is more than N.
Through sampling module 20, in order to obtain the storage battery voltage sampling data after the vehicle stalls at every turn to can confirm the low voltage protection value who is used for on-vehicle electronic equipment according to the change of storage battery voltage data developments dynamically, use the date that the vehicle stalls for any time as the starting point, with preserve collection frequency and preserve time interval and gather storage battery voltage sampling data after the vehicle stalls in the time quantum of the Nth day to the Mth day after this date in proper order, N more than or equal to 1 here, M is greater than N.
It should be noted that the preset sampling frequency may be determined according to actual sampling requirements, precision requirements of the sampled data, performance of the data acquisition device, and other factors, if the preset sampling frequency for sampling is too large, the precision of subsequent data calculation may be low, and if the preset sampling frequency for performing sampling is too small, the amount of the acquired data may be too large, and the workload of subsequent data calculation may be too large. For example, the storage battery voltage data can be sampled for 1 time every minute, namely the storage battery voltage sampling data after the vehicle is flamed out is collected every 1 minute, so that the calculation accuracy and the calculation efficiency of the sampling data can be considered.
It should be noted that the preset time interval can be determined according to actual sampling requirements, and the preset time interval can be reasonably determined according to the required low-voltage protection value of the specified date. For example, to obtain the under-voltage protection value on the 10 th day after the vehicle is turned off for the first time, the preset time interval here may be set to 7 days, 0: and collecting battery voltage sampling data of preset time, such as 10 minutes, after each vehicle is shut off in a 24:00 time period from the 00 th day to the 7 th day. Of course, the preset time interval can be adjusted at any time according to needs.
And the determining module 30 is used for taking a weighted average value of all or part of the battery voltage sampling data from the Nth day to the Mth day after the crown block vehicle is flamed out, and determining the low-voltage protection value of the M +1 th day.
By the determination module 30, for the acquired nth day 0: 00 to day M24: 00 sampling data of all battery jar voltages after the vehicle is flamed out can adopt all sampling data or select effective partial sampling data, so as to take weighted average value of all sampling data or partial sampling data as the low-voltage protection value of the M +1 th day. For example, when the preset time interval is set to 7 days, on the 1 st day 0 after the first vehicle key-off: and in a 24:00 time period from 00 to 7 th day, collecting all battery voltage sampling data of preset time, such as 10 minutes, after the vehicle is shut off every time, and taking a weighted average value of all sampling data of the 7 day time period as a low-voltage protection value of the 8 th day.
Here, for convenience of calculation, all the sampled data may be selected to perform weighted averaging, and of course, all the obtained battery voltage sampled data may be primarily screened, for example, considering that there may be a certain fluctuation or error in the head and tail data in the battery voltage sampled data, the battery voltage sampled data at the head and tail may be rejected, so as to ensure the accuracy of subsequent data calculation. Therefore, the determination module 30 can sequence the battery voltage sampling data of a predetermined time, for example, 10 minutes after the crown block vehicle stalls from the nth day to the mth day to form a sampling data sequence, filter the battery voltage sampling data at the two ends of the sampling data sequence, take a weighted average value of the remaining battery voltage sampling data, for example, sequence all the sampling data according to size, and perform filtering operation on 5% of data at the head and 5% of data at the tail, wherein the filtering operation is to filter out high-voltage and low-voltage burr data generated by battery fluctuation, and the middle 90% of the sampling data is reserved to perform weighted averaging processing, so as to improve the accuracy and precision of the obtained low-voltage protection value.
An obtaining module 40, configured to set N to N +1 and M to M +1, perform operations through the sampling module 20 and the determining module 30 until M +1 is equal to a specified date to obtain the low-voltage protection value of the specified date.
With the acquisition module 40, since the preset time interval for performing sampling is not changed, the start and end times of the sampled time period are subsequently pushed back by one day in the process of each sampling, that is, N +1 is set, and M +1 is set, and then an operation is performed with the sampling module 20 and the determination module 30 until the date represented by M +1 is equal to the specified date, so that the low voltage protection value of the specified date can be acquired.
According to the above-mentioned embodiment, the preset time interval is set to 7 days, that is, M is equal to N +6, so that the battery voltage sampling data after the vehicle is flamed off for 7 continuous days can be collected. When N is 1, M is 7, in which case the pain oversampling module 20 may collect the battery voltage sampling data from day 1 to day 7 after the vehicle is first turned off, and by the determination module 30, for the collected day 1, 0: 00 to day 7 24:00 taking the weighted average of all or part of the battery voltage sampling data after the vehicle is flamed out as the low-voltage protection value on the 8 th day. The date is set by the acquisition module 40, and the operations are repeatedly performed by the sampling module 20 and the determination module 30, i.e., the acquisition continues for day 2, 0: the battery cell voltage sampling data collected in the period of 24:00 on the 8 th day is 24: and when the date is 00, obtaining the low-voltage protection value of the day 9, and so on until the low-voltage protection value of the day on the appointed date is obtained through the storage battery voltage sampling data 7 days before the appointed date.
According to the on-vehicle electronic equipment low pressure protection device that this disclosure provided can be according to the battery voltage sampling data after the vehicle of a period of collection is flamed out, be equivalent to historical battery voltage data, the low pressure protection value of vehicle battery is adjusted dynamically, thereby even to the vehicle battery of the different styles of different brands and even the vehicle battery is under the temperature condition of difference and in different old and new degree, also can carry out the low pressure protection of vehicle battery steadily, effectively prevent that the on-vehicle electronic equipment that the low protection value leads to lasts power consumptive and the on-vehicle electronic equipment part function of premature shutdown that the low pressure protection value leads to on the low side, effectively prolong the life of vehicle battery under the condition that does not influence on-vehicle electronic equipment function.
A third aspect of the present disclosure provides a storage medium, which is a computer-readable medium storing a computer program, which when executed by a processor implements the method provided in any embodiment of the present disclosure, including the following steps S11 to S14:
s11, setting an initial low-voltage protection value;
s12, collecting storage battery voltage sampling data from the Nth day to the Mth crown block after flameout at preset sampling frequency and preset time intervals, wherein N is more than or equal to 1, and M is more than N;
