[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] like Figure 1 As shown, a method for replacing a self-service device module is proposed. The method for replacing a self-service device module can be applied to a terminal. This embodiment is described by applying to a terminal as an example. The method for replacing a self-service device module specifically includes the following steps:

[0038] Step 102, obtaining device parameters of the self-service device containing the module to be replaced in the preset area, wherein the device parameters include: total working time, downtime, and number of failures of each module;

[0039] The preset area refers to a pre-set geographical area where self-service devices are distributed; the module to be replaced refers to the module in the self-service device that is predicted to need to be replaced. The device parameters refer to the device information of the self-service device, including: total working time, downtime, and number of failures of each module. The total working time refers to the sum of the working time of the self-service device, the downtime refers to the sum of the downtime of the self-service device, and the number of failures of each module refers to the number of failures of each module in the self-service device. The device parameters of the self-service device for the module to be replaced are obtained, which can be used to calculate the target replacement time of the module to be replaced.

[0040] Step 104, obtaining module parameters of the module to be replaced in the preset area, the module parameters including: standard replacement time;

[0041] The module to be replaced refers to the module in the self-service device that is predicted to need to be replaced; the module parameter of the module to be replaced refers to the module information of the module in the self-service device that is predicted to need to be replaced, including: standard replacement time. The standard replacement time is the recommended usage time of the module to be replaced in the self-service device, and the standard replacement time is a reasonable usage time of the module to be replaced based on the nature of the module to be replaced. The recommended usage time of the module to be replaced is used as the standard replacement time, which can be used as a reference replacement time to calculate the target replacement time of the module to be replaced.

[0042] Step 106, calculating a target replacement time according to the device parameters and the module parameters;

[0043] Among them, the target replacement time refers to the replacement time of the module that may need to be replaced in the self-service device, that is, the replacement time of the module to be replaced. The target replacement time can be calculated based on the device parameters of the self-service device and the module parameters of the self-service device module. Because the target replacement time is related to the device parameters and the module parameters, the target replacement time can be calculated based on the device parameters and the module parameters. In one embodiment, the target replacement time can be calculated based on the total working time, downtime, number of failures of each module in the device parameters, and the standard replacement time in the module parameters. In one embodiment, the failure rate of each module to be replaced can be calculated based on the downtime, total working time and number of failures of each module in the device parameters. For example, the failure rate of each module to be replaced can be the quotient of the product of the total working time, downtime and number of failures of each module; the target replacement time can be calculated based on the failure rate of each module to be replaced, for example, by multiple square root calculations of the failure rate and the standard replacement time in the module parameters, and the resulting value is the target replacement time. According to the device parameters and module parameters of the self-service device, combined with the standard replacement time calculation, the target replacement time of the module to be replaced can be obtained. The target replacement time is the optimal replacement time, and the module to be replaced can be replaced according to the optimal replacement time.

[0044] Step 108: Replace the module to be replaced according to the target replacement time.

[0045] Among them, the target replacement time refers to the replacement time of the module that may need to be replaced in the self-service device, that is, the replacement time of the module to be replaced. The target replacement time can be calculated based on the device parameters of the self-service device and the module parameters of the self-service device module. According to the calculated target replacement time, the module to be replaced is replaced regularly. For example, assuming that the target replacement time of each module is calculated to be 44 days and 40 days, the module to be replaced should be replaced at 44 days and 40 days. The target replacement time obtained by calculation is the optimal replacement time for the module to be replaced. The module to be replaced is replaced according to the above target replacement time, so that the replacement cost of the self-service device module is minimized, and the module to be replaced is replaced in time within the optimal replacement time, which can ensure the sustainable normal operation of the self-service device, and replace the module before the self-service device module fails, thereby increasing the user experience.

[0046] like Figure 2 As shown, in one embodiment, calculating the target replacement time according to the device parameters and the module parameters includes:

[0047] Step 202, calculating the failure rate of each module to be replaced according to the total working time, downtime and the number of failures of each module.

[0048] The failure rate of each module to be replaced refers to the probability of failure of each module predicted to be replaced in the self-service device. In one embodiment, the failure rate of each module to be replaced can be calculated based on the total working time, downtime and the number of failures of each module. For example, if the downtime of the terminal is T, the total working time of the terminal is W, and the number of failures of each module is A1, A2, A3...An, the failure rate of each module can be calculated based on the above equipment parameters. The failure rate of each module can be expressed as a1, a2, a3...an, and the calculation method of the failure rate of each module ai can be:

[0049]

[0050] For example, suppose the downtime T of a self-service device is 1 day, the total operating time W is 200 days, the number of failures of each module is 1 time and 3 times respectively, and the recommended service life of the corresponding module is 40 days and 40 days. Therefore, the standard replacement time of each module to be replaced is 40 days and 40 days respectively; then the failure rate is calculated, and the failure rate of each module to be replaced is a1: 1×1 / 200=0.5%, a2=1×3 / 200=1.5%. Then the failure rate of each module to be replaced is a1=0.5% and a2=1.5% respectively. The failure rate a of each module calculated according to the above formula i , which can reflect the failure degree of each module of the self-service device, and can also be used to calculate the target replacement time of the module to be replaced, which is the optimal replacement time of the module to be replaced.

[0051] Step 204 , calculating a target replacement time for each module to be replaced according to the failure rate of each module to be replaced and the standard replacement time for each module to be replaced.

[0052] The failure rate of each module to be replaced refers to the probability of failure of each module predicted to be replaced in the self-service device, and the standard replacement time of each module to be replaced refers to the recommended usage time of each module predicted to be replaced. In one embodiment, the target replacement time can be calculated based on the above failure rate and standard replacement time, for example: the failure rate a of each module is calculated i After that, the failure rate of each module can be i The target replacement time is calculated by using the module parameters of the self-service device module. For example, let N be the standard replacement time of the module (unit: day), let M be the template replacement time of the module (unit: day), and calculate according to the following formula:

[0053] (1-a i ) N =P

[0054] If the obtained number P is not greater than 80%, the target replacement time of the module is M = N days, that is, the target replacement time is equal to the standard replacement time; if P is greater than 80%, the next step of calculation is performed:

[0055] (1-a i ) M =80%

[0056] Solve the above equation, round down the calculated M, and the integer obtained is the target replacement time of the module. According to the device parameters and module parameters of the self-service device, combined with the standard replacement time calculation, the target replacement time of the module to be replaced can be obtained, that is, the optimal replacement time of the module to be replaced. The target replacement time corresponding to the module to be replaced obtained by the above calculation method can reduce the replacement cost of the module to be replaced in a targeted manner.

[0057] like Figure 3 As shown, in one embodiment, the target replacement time of each module to be replaced is calculated according to the failure rate of each module to be replaced and the standard replacement time of each module to be replaced, including:

[0058] Step 302: Calculate a target replacement rate corresponding to each module to be replaced according to the failure rate of each module to be replaced and the standard replacement time of each module to be replaced.

[0059] Among them, the failure rate of each module to be replaced refers to the probability of failure of each module predicted to be replaced in the self-service device; the standard replacement time of each module to be replaced refers to the recommended usage time of each module predicted to be replaced; the target replacement rate of each module to be replaced refers to the probability of replacement of each module predicted to be replaced based on the failure rate. The target replacement rate can be calculated based on the failure rate and the standard replacement time. For example, let the target replacement rate be P, and let the failure rate of each module to be replaced be a i , let N be the standard replacement time of the module (unit: day), and calculate the target replacement rate P according to the following formula:

[0060] P=(1-a i ) N

[0061] According to the failure rate of each module to be replaced and the standard replacement time of each module to be replaced, the probability of the module to be replaced needing to be replaced can be calculated, and the value P calculated by the above formula is used as the target replacement rate.

[0062] Step 304: Obtain a preset replacement rate.

[0063] Among them, the preset replacement rate refers to the probability of replacement corresponding to each module that is predicted to be replaced. The preset replacement rate can be used as a theoretical replacement rate and compared with the target replacement rate to determine whether the target replacement rate meets the requirements. That is, compare the preset replacement rate and the target replacement rate: when the target replacement rate is not greater than the preset replacement rate, the target replacement rate is judged to meet the requirements, so that the target replacement time is equal to the standard replacement time; when the target replacement rate is greater than the preset replacement rate, the target replacement rate is judged to be unsatisfactory and further calculation is required to obtain the target replacement time. In one embodiment, it is assumed that the preset replacement rate is 80%, and the target replacement rate is set to P. When P≤80%, the target replacement time is judged to be equal to the standard replacement time; when P>80, the next step of the target replacement time calculation is performed. By obtaining the preset replacement rate, it can be used as a control value of the target replacement rate, so that the target replacement time can be more accurately judged and calculated.

[0064] Step 306: Calculate the target replacement time of each module to be replaced according to the preset replacement rate and the target replacement rate.

[0065] The preset replacement rate refers to the probability of replacement of each module that is predicted to be replaced, and the target replacement rate refers to the probability of replacement of each module that is predicted to be replaced. In one embodiment, the target replacement time can be calculated by comparing the preset replacement rate and the target replacement rate. For example, if the failure rate of the module to be replaced is a=1.5%, the preset replacement rate is 80%, and the standard replacement time of the module to be replaced is N=40 days, then the corresponding target replacement rate is calculated to be P=(1-1.5%). 40 ≈0.5463<80%, the target replacement rate at this time is less than the preset replacement rate, then the target replacement time of the module to be replaced is equal to the standard replacement time, that is, M=N=40 days; when the failure rate of the module to be replaced is a=0.5%, the preset replacement rate is 80%, and the standard replacement time of the module to be replaced is N=40 days, then the corresponding target replacement rate is calculated to be P=(1-0.5%) 40 ≈0.8183>80%. At this time, the target replacement rate is greater than the preset replacement rate, so the next step of calculation can be performed according to the formula:

[0066] (1-a i ) M =80%

[0067] Solve the above equation and round down the calculated M to the integer, and the integer is the target replacement time of the module, such as: (1-0.5%) M=80%, and M≈44 days is calculated, so the target replacement time is 44 days. According to the target replacement rate and the preset replacement rate, the target replacement time of each module to be replaced is processed predictably, and according to the actual situation of each module to be replaced, the target replacement time of the module to be replaced is accurately obtained.

[0068] In one embodiment, Figure 4 As shown, the module parameters also include: the replacement cost of each module to be replaced; and replacing the module to be replaced according to the target replacement time includes:

[0069] Step 402, dividing the modules to be replaced into intervals according to the replacement cost of each module to be replaced and the failure rate of each module to be replaced, so that the cumulative sum of the failure probabilities corresponding to each interval is equal;

[0070] Among them, the replacement cost of each module to be replaced refers to the sum of various expenses required to replace the self-service equipment module, such as: replacement cost = transportation cost + employee wages + other expenses; the failure rate of each module to be replaced refers to the probability of failure corresponding to each module that is predicted to be replaced; the cumulative sum of the failure probabilities corresponding to each interval refers to the sum of the failure rates of all modules to be replaced in a single interval. Dividing the modules to be replaced into intervals according to the replacement cost and failure rate so that the cumulative sum of the failure probabilities corresponding to each interval is equal can be: sorting the replacement cost of each module to be replaced from small to large, and dividing the intervals according to the replacement cost ranking so that the cumulative sum of the failure rates of multiple groups of modules to be replaced in each interval sorted by replacement cost is equal. By dividing the intervals and coordinating the intervals, the efficiency of the modules to be replaced can be optimized.

[0071] Step 404: Obtain the normal life span of each spare part module in the regional spare parts warehouse of the preset area.

[0072] Among them, the spare parts module is a spare module used to replace the module to be replaced, the regional spare parts warehouse is a warehouse for storing spare parts modules, and the normal life of the spare parts module refers to the maximum normal working time of the spare parts module. The normal life of each spare parts module can be obtained and matched with the module to be replaced in each interval, so that the corresponding spare parts module can be selected to replace the module to be replaced.

[0073] Step 406: Determine the interval corresponding to each spare module according to the normal life span of the spare module.

[0074] Among them, the normal life span of the spare parts module refers to the maximum normal working time of the spare parts module, the interval corresponding to each spare parts module refers to the interval of the module to be replaced corresponding to each spare parts module, and the number of intervals of the module to be replaced is equal to the number of spare parts modules. In one embodiment, the normal life span of the spare parts module can be sorted in order from small to large, and one-to-one correspondence is made with the intervals of the module to be replaced divided according to the replacement cost of the module to be replaced and the failure rate of the module to be replaced, so that the interval corresponding to each spare parts module can be determined. According to the normal life span of the spare parts module, the interval corresponding to the spare parts module is determined, and the replacement demand of the module to be replaced can be met.

[0075] Step 408: Obtain a target spare part module corresponding to each module to be replaced according to the interval corresponding to the module to be replaced and the interval corresponding to the spare part module.

[0076] Among them, the target spare parts module refers to a spare module corresponding to the module to be replaced and used to replace the module to be replaced. The interval corresponding to the module to be replaced refers to the interval of the module to be replaced divided according to the replacement cost of the module to be replaced and the failure rate of the module to be replaced. The interval corresponding to the spare parts module refers to the interval of the module to be replaced corresponding to each spare parts module, and the number of intervals of the module to be replaced is equal to the number of spare parts modules. Since the number of intervals of the module to be replaced is equal to the number of spare parts modules, the intervals corresponding to the spare parts module can be matched one by one with the intervals corresponding to the module to be replaced. According to the matching interval relationship, the target spare parts module corresponding to each module to be replaced can be obtained. By obtaining the target spare parts module corresponding to each module to be replaced, the most suitable spare parts module for each module to be replaced can be obtained.

[0077] Step 410: Replace the module to be replaced with the target spare module according to the target replacement time.

[0078] Among them, the target replacement time refers to the replacement time of the module that is predicted to be replaced in the self-service device, that is, the replacement time of the module to be replaced; the module to be replaced refers to the module that is predicted to be replaced; the target spare module is a spare module corresponding to the module to be replaced and used to replace the module to be replaced. Because there is a one-to-one correspondence between each module to be replaced and the target spare module, the module to be replaced can be replaced with the target spare module at the target replacement time according to the one-to-one correspondence. Replacing the module to be replaced with the target spare module according to the target replacement time can ensure that the module to be replaced is replaced with the most suitable spare module at the best replacement time, so that the replacement method of the self-service device module is optimized.

[0079] like Figure 5As shown, in one embodiment, the modules to be replaced are divided into intervals according to the replacement cost of each module to be replaced and the failure rate of each module to be replaced, so that the failure probability corresponding to each interval is equal, including:

[0080] Step 502, obtaining the number of preset intervals in the preset area.

[0081] The number of preset intervals refers to the number of intervals of the module to be replaced that are pre-set and divided according to the replacement cost of the module to be replaced and the failure rate of the module to be replaced. Because the payment probability corresponding to each interval must be equal, the number of divided intervals needs to be obtained, so that it can be used to calculate the average replacement probability of each preset interval.

[0082] Step 504 , calculating an average replacement probability corresponding to each interval according to the failure rate of each module to be replaced, the number of preset intervals and the replacement cost of each module to be replaced.

[0083] Among them, the failure rate of each module to be replaced refers to the probability that each self-service equipment module that is predicted to be replaced may fail; the number of preset intervals refers to the number of intervals of the modules to be replaced that are pre-set and divided according to the replacement cost of the modules to be replaced and the failure rate of the modules to be replaced; the replacement cost of each module to be replaced is the sum of various expenses required to replace the self-service equipment module; the average replacement probability refers to the probability that the modules to be replaced in each interval may be replaced. The average replacement probability corresponding to each interval can be calculated based on the failure rate of each module to be replaced, the number of preset intervals and the replacement cost of each module to be replaced. For example: sort the replacement cost of each module to be replaced in order from small to large, and you can get the order of the modules to be replaced sorted by replacement cost; according to the order of the above-mentioned order of the modules to be replaced, add up the failure rate of each module to be replaced to get the total failure rate of all the modules to be replaced; calculate the quotient of the above-mentioned total failure rate and the number of preset intervals, and the obtained quotient is the average replacement probability corresponding to each interval.

[0084] Step 506: Divide the modules to be replaced into intervals according to the average replacement probability and the replacement cost of each module to be replaced, and determine an interval corresponding to each module to be replaced.

[0085] Among them, the average replacement probability refers to the probability that the module to be replaced in each interval may be replaced, and the replacement cost of each module to be replaced refers to the sum of various expenses required to replace the self-service equipment module. In one embodiment, each module to be replaced is sorted in order from small to large according to the replacement cost, and all modules to be replaced are divided into intervals, so that the cumulative sum of the failure rates of the modules to be replaced in each interval is equal to the average replacement probability, and the obtained interval is the interval corresponding to the module to be replaced. By dividing the modules to be replaced into intervals and then performing regional overall configuration according to the divided intervals, the interval operation cost can be minimized and the requirement of maximizing benefits can be met.

[0086] like Figure 6 As shown, in one embodiment, the number of preset intervals is the number of spare modules, and the modules to be replaced are divided into intervals according to the average replacement probability and the replacement cost of each module to be replaced, and the interval corresponding to each module to be replaced is determined, including:

[0087] Step 602: sort the modules to be replaced in ascending order according to the replacement cost of each module to be replaced.

[0088] The replacement cost of each module to be replaced refers to the sum of various expenses required to replace the self-service device module. Each module to be replaced is sorted in order from small to large according to the replacement cost, and the order of the modules to be replaced can be obtained, so that the replacement of the self-service device modules can be arranged in a coordinated manner to minimize the expected value of the module replacement cost.

[0089] Step 604, the failure rates of the modules to be replaced are sequentially accumulated according to the ranking to obtain a probability accumulation sum, and when the probability accumulation sum is equal to the average replacement probability, the modules to be replaced participating in the accumulation are divided into the same interval.

[0090] The order is obtained by sorting the replacement cost of each module to be replaced in ascending order, the average replacement probability is the probability that the module to be replaced in each interval may be replaced, and the failure rate of each module to be replaced is the probability that each self-service equipment module that is predicted to need to be replaced may fail. Since the probability that the module to be replaced in each interval is to be replaced is the same, the sum of the failure rates of the modules to be replaced in each interval must be equal to the average replacement probability. That is, the order is obtained by sorting the replacement cost of each module to be replaced in ascending order, and the failure rates of the modules to be replaced are accumulated in sequence until the sum of the failure rates is equal to the average replacement probability. The result can meet the requirement that the probability of replacement of the modules to be replaced in each interval is the same, and the modules to be replaced that participate in the accumulation are divided into the same interval. By limiting and dividing the intervals of the modules to be replaced by sorting the average replacement probability and the replacement cost, the requirement of the lowest replacement cost of the modules to be replaced can be met.

[0091] Step 606, re-accumulate the failure rates of the modules to be replaced that are not included in the accumulation according to the sorting. When the probability accumulation sum is equal to the average replacement probability, divide the modules to be replaced that are included in the accumulation into the same interval, and so on, determine the interval corresponding to each module to be replaced.

[0092] Among them, the order refers to the order obtained by sorting the replacement cost of each module to be replaced in ascending order, the average replacement probability refers to the probability that the module to be replaced in each interval may be replaced, and the failure rate of each module to be replaced refers to the probability that each self-service equipment module that is predicted to need to be replaced may fail. Since the probability of replacement of the modules to be replaced in each interval is to be the same, the sum of the failure rates of the modules to be replaced in each interval must be equal to the average replacement probability. The order is obtained by sorting the replacement cost of each module to be replaced in ascending order, so that the cumulative sum of the failure rates of the modules to be replaced is equal to the average replacement probability, and the modules to be replaced that participate in the accumulation each time are divided into the same interval. By analogy, multiple divided intervals of the modules to be replaced can be obtained, so that the interval corresponding to each module to be replaced can be determined. The modules to be replaced are divided into intervals according to the replacement cost of the modules to be replaced, and the modules to be replaced are comprehensively configured within the interval, so that the interval replacement efficiency is optimized.

[0093] like Figure 7 As shown, in one embodiment, determining the interval corresponding to each spare module according to the normal life span of the spare module includes:

[0094] Step 702: sort the spare modules in ascending order according to the normal life span of the spare modules to obtain a sorting result for each spare module.

[0095] The normal life span of the spare module refers to the maximum normal working time of the spare module. The spare modules are sorted in ascending order according to their normal life spans, and the sorting result of the spare modules can be obtained, so that the module to be replaced can be matched with the most suitable spare module to be replaced within the optimal replacement time, so that the spare modules with longer normal life span can be used to replace the modules with higher cost to be replaced as much as possible, so as to minimize the cost of operation and maintenance.

[0096] Step 704: Determine the interval corresponding to the spare part module according to the sorting result of each spare part module.

[0097] Among them, the sorting result of the spare parts module refers to sorting the spare parts modules in the order of their normal life span from small to large to obtain the sorting result. Since the number of preset intervals is the number of spare parts modules, there is a one-to-one correspondence between the spare parts modules and the number of preset intervals. In one embodiment, according to the sorting result of the spare parts module, the preset intervals sorted in the order of the sum of the replacement costs from small to large can be matched one by one to determine the interval corresponding to the spare parts module. Spare parts modules with different normal working time can be matched to the interval of the module to be replaced that is most suitable for them, so that the expected value of the replacement cost of the spare parts module is minimized.

[0098] like Figure 8 As shown, in one embodiment, replacing the module to be replaced according to the target replacement time includes:

[0099] Step 802, determine whether the target replacement time is equal to the standard replacement time. When the target replacement time is equal to the standard replacement time, go to step 804; when the target replacement time is not equal to the standard replacement time, go to step 806.

[0100] The target replacement time refers to the replacement time of the module that may need to be replaced in the self-service device, that is, the replacement time of the module to be replaced; the standard replacement time is the recommended use time of the module to be replaced in the self-service device, and the standard replacement time is a reasonable use time of the module to be replaced based on the properties of the module to be replaced. By determining whether the target replacement time is equal to the standard replacement time, the optimal replacement time of the module to be replaced can be obtained. In one embodiment, whether the two are equal can be determined by calculation: Let a iis the failure rate of the module to be replaced, N is the standard replacement time of the module (unit: day), M is the template replacement time of the module (unit: day), P is the target replacement rate, P1 is the preset replacement rate, and it is assumed that the preset replacement rate P1 = 80%. If the target replacement rate is not greater than the preset replacement rate, that is, P≤P1, the target replacement time of the module is M = N days, that is, the target replacement time is equal to the standard replacement time; if the target replacement rate is greater than the preset replacement rate, that is, P>P1, the target replacement time of the module is M, that is, the target replacement time is not equal to the standard replacement time.

[0101] Step 804: When the target replacement time is equal to the standard replacement time, replace the module to be replaced according to the standard replacement time.

[0102] The target replacement time refers to the replacement time of the module that may need to be replaced in the self-service device, that is, the replacement time of the module to be replaced; the standard replacement time is the recommended use time of the module to be replaced in the self-service device, and the standard replacement time is a reasonable use time of the module to be replaced based on the properties of the module to be replaced. When the target replacement time is equal to the standard replacement time, the standard replacement time is the optimal replacement time of the module to be replaced. Replacing the module to be replaced according to the standard replacement time can ensure that the module to be replaced is replaced within the optimal replacement time, ensuring that the self-service device can work normally.

[0103] Step 806: When the target replacement time is not equal to the standard replacement time, replace the module to be replaced according to the target replacement time.

[0104] Among them, the target replacement time refers to the replacement time of the module that may need to be replaced in the self-service device, that is, the replacement time of the module to be replaced; the standard replacement time is the recommended use time of the module to be replaced in the self-service device, and the standard replacement time is a reasonable use time of the module to be replaced based on the nature of the module to be replaced. When the target replacement time is not equal to the standard replacement time, the target replacement time is the optimal replacement time of the module to be replaced. Replacing the module to be replaced according to the target replacement time can ensure that the module to be replaced is replaced within the optimal replacement time, ensuring that the self-service device can continue to work normally and improve the user experience.
