And obtaining the time range of the fault duration of each device based on the fault rate and the preset fault duration upper limit time. The user terminal 120 may select the operating time limit of the device according to the intersection of the time range of continuous operation and the time range of fault duration.
In the embodiment of the present invention, the device 110 includes a cloud server, a server, and other devices having a service life, and the user terminal 120 may obtain a failure rate of the device 110 in a preset unit time according to the collected data, so as to calculate the working time limit of the device.
In the embodiment of the present invention, the ue 120 includes a physical device of a smart phone, a desktop computer, a tablet computer, a notebook computer, a digital assistant, a smart wearable device, and the like, and may also include software running in the physical device, such as a computing program and the like.

Referring to fig. 2, a method for determining an operation time limit of a device, which is applicable to a user terminal side, is shown, and the method includes:
s210, acquiring the fault rate of equipment in a preset unit time based on historical data in the preset unit time;
further, referring to fig. 3, the obtaining the failure rate of the device in the preset unit time based on the historical data in the preset unit time includes:
s310, acquiring the working quantity of equipment in preset unit time;
s320, acquiring the number of faults of equipment with faults in preset unit time;
s330, acquiring the failure rate of the equipment in the preset unit time according to the failure number and the working number.
Specifically, the preset unit time is selected as the case may be, and may be one day, one month, one year, ten years, and the like. Since the failure rate of the equipment is basically kept unchanged under the condition that the production and the use meet the specifications, the failure rate of the equipment can be directly determined based on the preset historical data in unit time. For example: assuming that the device is a cloud server, acquiring the number of cloud servers which are working in a preset unit time, and acquiring the number of cloud servers which have faults in the preset unit time, wherein the ratio of the number of the cloud servers which have faults to the number of the cloud servers which are working in the preset unit time is the fault rate of the cloud servers in the preset unit time.

s420, calculating the range of the continuous working time of the equipment, which is not less than the preset continuous working lower limit time, based on the fault rate;
and S430, taking the calculated range of the continuous working time as a first working time range.
Specifically, referring to fig. 5, the continuous operation time is a time for the device to perform continuous normal operation. The relation between the continuous working time and the fault duration and the working time limit is that the continuous working time and the fault duration alternately appear to form the working time limit when the equipment works. Specifically, a fault occurs after a certain time of continuous operation, the fault is removed after the fault lasts for a period of time, and the equipment continues to operate, namely the continuous operation time and the fault duration are mutually interlaced time.
The method comprises the steps of determining at least how many preset unit times the expected equipment continuously and normally works on average, namely determining preset continuous working lower limit time, and obtaining the continuous working lower limit time according to requirements and specific conditions. For example, the time for which the apparatus can operate for 20 years is desired, and if the environment of the apparatus is suitable, the time for setting the lower limit time for continuous operation can be suitably extended to 23 to 25 years, and if the environment of the apparatus is severe, the time for setting the lower limit time for continuous operation can be shortened to 15 to 17 years.
And under the condition of determining the fault rate, calculating the range of continuous working time of the equipment, wherein the range of the continuous working time can ensure that the average continuous normal working time of the equipment under the condition of determining the fault rate is not lower than the preset continuous working lower limit time.
If the failure rates of the different devices are the same, setting the serial number of the device as i, i belongs to {1,2, · · h }, setting the failure rate as p, and presetting the lower limit time of continuous operation as tiThe operating time of the apparatus is TiAnd calculating the range of the continuous working time of the equipment which is not lower than the preset continuous working lower limit time by the following formula to obtain a first working time range.
The first operating time range for each device at the same failure rate may be calculated based on the above formula.
If the failure rates of different devices are different, the serial number of the device is set as i, i belongs to {1,2, · · h }, and the failure rate is piPresetting the lower limit time of continuous operation as tiThe operating time of the apparatus is TiThe continuous working time of the equipment which is not less than the preset continuous working lower limit time can be calculated by the following formulaAnd making a time range to obtain a first working time range. When the failure rates of different devices are different, each device can be specifically positioned through the serial numbers of the devices, so that the failure rate of the corresponding device can be obtained for calculation.
The first operating time range for each device at different failure rates can be calculated based on the above formula.
Based on the failure rate of the equipment obtained according to the historical data, the continuous working time range which is not lower than the preset continuous working lower limit time can be determined, so that the working time limit can meet the requirement of the lowest continuous working time, and the continuous working time of the equipment is ensured.
Further, referring to fig. 6, the calculating the range of the continuous operation time of the device not less than the preset continuous operation lower limit time based on the failure rate includes:
s610, calculating a plurality of continuous working probabilities of the equipment in continuous working at different integral multiples in preset unit time based on the fault rate;
s620, obtaining the theoretical working time limit of the continuous working of the equipment according to the plurality of continuous working probabilities;
and S630, calculating the range of the continuous working time of the equipment according to the theoretical working time limit of the continuous working and the preset continuous working lower limit time.
Specifically, when calculating the range of the continuous operation time of the equipment based on the above formula, if the failure rates of the respective equipments are the same, under the condition that the failure rate of the equipment is p, the continuous operation probabilities of 1,2, … n preset unit times that the equipment can continuously and normally operate are respectively obtained, where n is an integer. And calculating the theoretical working time limit of the continuous working of the equipment based on the continuous working probability, namely an expression on the left of the unequal number of the formula. The theoretical working time limit can be enabled to be not lower than the first working time range of the equipment when the preset continuous working lower limit time is achieved through inequality calculation, and the time that the equipment can continuously and normally work is guaranteed not to be lower than a real expected value.
For example, if the equipment failure rate is 2% per year and the unit time is 1 year, the probability of the equipment failing within one year of continuous operation, the probability of the equipment failing within two years of continuous operation, and the like need to be obtained, and finally the probability of the equipment failing within n years of continuous operation is obtained, if the preset continuous operation time limit is 10 years, the equipment needs to be continuously operated for at least 10 years under the condition that the annual failure rate is 2%, and the first operation time range of the equipment can be obtained by substituting the numerical values into the above formula.
Specifically, when the range of the continuous operating time of the equipment is calculated based on the above formula, if the failure rates of the respective equipments are different, the failure rate of the equipment is piUnder the condition of (1), respectively calculating the continuous operation probability of 1,2 and … n preset unit times of continuous normal operation of the equipment based on different failure rates of each equipment, wherein n is an integer. And calculating the theoretical working time limit of the continuous working of the equipment based on the continuous working probability, namely an expression on the left of the unequal number of the formula. The theoretical working time limit can be enabled to be not lower than the first working time range of the equipment when the preset continuous working lower limit time is achieved through inequality calculation, and the time that the equipment can continuously and normally work is guaranteed not to be lower than a real expected value.
For example, under the condition that one-third of the equipment failure rates are 2% per year and two-thirds of the equipment failure rates are 3% per year, the failure rates of different equipment are different, and therefore, the calculation needs to be performed on different equipment respectively. Under the condition that the failure rate is 2% per year, the unit time is 1 year, the probability that the equipment fails within one year of continuous operation, the probability that the equipment fails within two years of continuous operation and the like needs to be calculated, the probability that the equipment fails within n years of continuous operation is finally obtained, if the preset continuous operation time limit is 10 years, under the condition that the annual failure rate is 2%, the equipment needs to be continuously operated for at least 10 years, and the first operation time range of the one-third equipment can be obtained by substituting various numerical values into the formula.
If the preset continuous operation time limit is 10 years, at least 10 years of continuous operation of the equipment is finally required under the condition that the annual fault rate is 3%, and the numerical values are substituted into the formula, so that the first operating time range of the other two thirds of the equipment can be obtained.
S230, obtaining a second working time range of each device based on the fault rate and preset fault duration upper limit time;
further, referring to fig. 7, the obtaining the second operating time range of each device based on the failure rate and the preset failure duration upper limit time includes:
s710, determining preset fault duration upper limit time, wherein the preset fault duration upper limit time is preset fault duration upper limit time of equipment;
s720, calculating the fault duration range of the equipment which is not higher than the preset fault duration upper limit time based on the fault rate;
and S730, taking the range of the fault duration as a second working time range.
Specifically, how many preset unit times the device is expected to operate at most on average, that is, the preset upper limit time of the fault duration is determined, and the upper limit time of the fault duration may be obtained according to the demand and the specific situation. For example, the upper limit time of the fault duration of the equipment is expected to be 10 minutes, and in the case of qualified equipment and appropriate environment, the upper limit time of the fault duration can be appropriately shortened and the value can be taken between 7 and 9 minutes, and in the case of severe environment, the upper limit time of the fault duration can be appropriately lengthened and the value can be taken between 11 and 13 minutes. And calculating the range of the fault duration time of the equipment under the condition of fault rate determination, wherein the range of the fault duration time can ensure that the average time of the equipment under the condition of fault rate determination for continuously working is not higher than the preset fault duration upper limit time.
If the failure rates are the same, setting the serial number of the equipment as i, i belongs to {1,2, · · h }, setting the failure rate as p, and setting the preset failure duration upper limit time as biThe operating time of the apparatus is TiAnd calculating the range of the equipment fault duration time which is not higher than the preset fault duration upper limit time through the following formula to obtain a second working time range.
A second operating time range for each device at the same failure rate may be calculated based on the above formula.
If the failure rates are different, the serial number of the equipment is set as i, i belongs to {1,2, · · h }, and the failure rate is set as piThe preset fault duration upper limit time is biThe operating time of the apparatus is TiAnd calculating the range of the equipment fault duration time which is not higher than the preset fault duration upper limit time through the following formula to obtain a second working time range. When the failure rates of different devices are different, the number of the device can be specifically positioned to each device, so that the failure rate of the corresponding device can be obtained for calculation.
A second operating time range for each device at a different failure rate may be calculated based on the above formula.
Based on the failure rate of the equipment obtained through the historical data, the failure duration range which is not higher than the preset failure duration upper limit time can be determined, so that the working time limit can meet the requirement of the highest failure duration time, and the failure duration of the equipment is ensured not to influence the working condition of the equipment.
Further, referring to fig. 8, the calculating a range of the failure duration of the device not higher than the preset failure duration upper limit time based on the failure rate includes:
s810, calculating a plurality of fault persistence probabilities of the equipment in different integer multiples of preset unit time based on the fault rate;
s820, obtaining the fault continuous theoretical working time limit of the equipment according to the multiple fault continuous probabilities;
and S830, calculating the range of the fault duration of the equipment according to the theoretical working time limit of the fault duration and the preset fault duration upper limit time.
S240, determining the working time limit of each device according to the first working time range and the second working time range.
Specifically, when calculating the range of the equipment fault duration time based on the above formula, if the fault rates are the same, the fault duration probabilities of 1,2, and … n preset unit times of equipment fault duration are respectively obtained under the condition that the fault rate of the equipment is p, where n is an integer. And calculating the theoretical working time limit of the fault duration of the equipment based on the fault duration probability, namely the expression on the left side of the unequal number of the formula. The inequality calculation can enable the theoretical working time limit to be not higher than the second working time range of the equipment when the preset fault duration upper limit time is reached, and the time for which the equipment can carry out fault duration is not higher than a real expected value.
For example, if the equipment failure rate is 2% per year, and the unit time is 1 year, it is necessary to obtain the probability that the equipment will fail and continue to fail in one year of operation, the probability that the equipment will fail and continue to fail in two years of operation, and the like, and finally obtain the probability that the equipment will fail and continue to fail in n years of operation, and if the preset upper limit time for failure duration is 15 minutes, then the probability that the equipment will fail and continue to fail in n years of operation is 15 minutes or less, and the second operating time range of the equipment can be obtained by substituting the numerical values into the above formula under the condition that the equipment failure rate is 2%.
When the range of the equipment fault duration is calculated based on the formula, if the fault rates are different, the equipment fault duration is calculatedFailure rate at the device is piUnder the condition (1), based on different failure rates of the devices, failure continuation probabilities of 1,2 and … n preset unit times of device failure continuation are respectively obtained, wherein n is an integer. And calculating the theoretical working time limit of the fault persistence of each device based on the fault persistence probability, namely an expression on the left of the unequal number of the formula. The inequality calculation can enable the theoretical working time limit to be not higher than the second working time range of the equipment when the preset fault duration upper limit time is reached, and the time for which the equipment can carry out fault duration is not higher than a real expected value.
For example, the unit time is 1 year under the condition that one third of the equipment failure rate is 2% per year, and the other two thirds of the equipment failure rate is 3% per year. And respectively calculating the probability that the equipment fails and continues to fail within one year when working under the condition that the failure rate is 2% per year, the probability that the equipment fails and continues to fail within two years when working, and the like, and finally obtaining the probability that the equipment fails and continues to fail within n years when working, wherein if the preset upper limit time for failure duration is 15 minutes, the time for failure occurrence and continues to fail within n years when working is not more than 15 minutes under the condition that the failure rate is 2%, and each numerical value is substituted into the formula, so that the second working time range of one third of the equipment can be obtained.
And under the condition that the fault rate is 3% per year, the probability that the equipment fails and continues to fail within one year when working, the probability that the equipment fails and continues to fail within two years when working and the like are finally obtained, if the preset upper limit time for the fault duration is 15 minutes, under the condition that the fault rate is 3%, the time for the fault to occur and continue to fail within n years of working is finally required to be less than or equal to 15 minutes, and the numerical values are substituted into the formula, so that the second working time range of the other two thirds of equipment can be obtained.
Further, referring to fig. 9, the determining the preset operating time of each device according to the first operating time range and the second operating time range includes:
s910, acquiring an intersection of the first working time range and the second working time range according to the first working time range and the second working time range;
s920, determining the working time limit of each device according to the working time in the intersection.
Specifically, the time included in the intersection of the first operating time range and the second operating time range may be the operating time limit of the device. And selecting one time in the intersection as the working time limit of the equipment according to the requirement.
In determining the preset operation time limit of each device, the accuracy of the method of determining the operation time limit of the device may be checked. After the working time limit is set for each device, the actual continuous working time and the actual fault duration of the device are collected, the number of devices meeting the preset working time is counted, and the percentage of the devices meeting the preset working time limit in actual application is obtained. In a specific example, a preset working time limit is set for all vehicle cloud servers, the average continuous normal working time and the average failure duration of the servers are counted, the vehicle cloud server proportion meeting the preset time is calculated, the number of the vehicle cloud servers meeting the requirement is divided by the total number of the vehicle cloud servers, and the vehicle cloud server proportion meeting the preset time in the average continuous normal working time is 95%, and the vehicle cloud server proportion meeting the preset time in the average failure duration is 95%.
In a particular embodiment, the device may be a cloud server of a vehicle. And determining a preset unit time, and calculating the fault rate of the cloud server according to historical data in the preset unit time. The failure rates of the different cloud servers may be different or the same, for example, the failure rate of the cloud servers may be a uniform annual failure rate of 1.2%, or the failure rate of some cloud servers may be an annual failure rate of 1.1%, or the failure rate of some cloud servers may be a different annual failure rate of 1.33%. The operating time limit of the cloud server of the vehicle may be calculated based on different failure rates or the same failure rate.
The number of the vehicle cloud servers is determined, the vehicle cloud servers are numbered, and the working time limit of the vehicle cloud servers is obtained based on the continuous working time and the fault duration. According to the fault of each vehicle cloud server, performing polling calculation on a first working time range related to continuous working time and a second working time range related to fault duration to obtain related data of each vehicle cloud server, and obtaining the working time limit of each vehicle cloud server based on the intersection of the first working time range and the second working time range.
In a particular embodiment, the first operating time range is obtained for a given failure rate. According to the operation requirement of the cloud server, presetting a continuous working lower limit time, and calculating a continuous working time range not lower than the continuous working lower limit time based on the determined fault rate to obtain a first working time range.
