Description

Technical Field

[0001] The present invention relates to the field of metering equipment maintenance management, and in particular to a metering equipment maintenance management system based on data analysis. Background Art

[0002] Metering equipment refers to devices, instruments, measuring tools and standard materials used to directly or indirectly measure the value of the measured object, such as water metering, electricity metering and gas metering equipment. Metering equipment is widely used in production, scientific research and people's lives, and plays a very important role in the entire metrology legislation.

[0003] At present, the maintenance and management of metering equipment in the existing technology is mostly to calibrate and clean it on a fixed periodic basis. This periodic maintenance method also has time limitations and insufficient maintenance accuracy, which will lead to a certain lag in the maintenance of metering equipment, making it difficult to ensure the accuracy and stability of the metering equipment, and increasing the subsequent maintenance cost and difficulty.

[0004] In view of the above technical problems, this application proposes a solution. Summary of the invention

[0005] In the present invention, when the metering equipment is maintained and managed, the metering equipment is no longer maintained through maintenance intervals of fixed frequency. Instead, the usage of the metering equipment is analyzed according to the workload and working hours of the metering equipment, and the usage is used as the basis for the maintenance of the metering equipment. At the same time, the external environment of the metering equipment is analyzed, and the environmental interference factors caused by environmental factors are fully combined, so that the maintenance of the metering equipment is more in line with the actual situation, and the problem of untimely maintenance or too frequent maintenance due to usage differences will not be caused. The problem that periodic maintenance work may cause untimely maintenance or too frequent maintenance of metering equipment is solved, and a metering equipment maintenance management system based on data analysis is proposed.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A metering equipment maintenance management system based on data analysis, comprising a usage statistics analysis unit, wherein the usage statistics analysis unit is used to count the workload performed by the metering equipment and obtain the maintenance record volume that can be used for maintenance analysis;

[0008] An environmental statistical analysis unit, which can obtain the operating environment of the metering device, analyze environmental interference factors according to the operating environment of the metering device, and generate a ratio coefficient for correcting the maintenance record amount;

[0009] A maintenance cycle analysis unit, which can monitor the maintenance cycle of the metering equipment through the maintenance record amount and the ratio coefficient, generate a maintenance signal, and collect statistics on the maintenance signal and send it to the maintenance management unit;

[0010] A device management unit, which can test the interconnection function of the metering device and send an alarm to the metering device with abnormal interconnection function according to the test result;

[0011] The maintenance management unit can collect statistics on all metering devices to be maintained and metering devices in alarm, generate maintenance paths according to intelligent algorithms, and send the maintenance paths to maintenance operation units.

[0012] As a preferred embodiment of the present invention, the statistical method for using the statistical analysis unit to calculate the workload completed by the metering equipment is:

[0013] Step 1: Number the metering equipment and upload the number to the cloud. After the maintenance or installation of the metering equipment is completed, the time is counted on the cloud according to the corresponding number and recorded as the total running time;

[0014] Step 2: When the gas or liquid passes through the metering device, it measures and records it as the passing amount, and uploads the measured passing amount to the cloud in real time. The cloud accumulates the passing amount of the metering device and records it as the total passing amount;

[0015] Step 3: When there is no gas or liquid passing through the inside of the measuring device, the time is counted and recorded as the static time, and all static times are accumulated and recorded as the total static time;

[0016] Step 4: Use the statistical analysis unit to obtain the maintenance record quantity of the metering equipment through formula analysis according to the total static time, the total throughput and the total running time, and use the statistical analysis unit to send the maintenance record quantity to the maintenance cycle analysis unit.

[0017] As a preferred embodiment of the present invention, when the environmental statistical analysis unit detects the operating environment of the metering device, the detected operating environment includes the internal temperature and external temperature of the metering device and the internal fluid pressure and fluid type of the metering device;

[0018] The environmental statistical analysis unit compares the external temperature of the metering device with a preset suitable operating temperature range. If the external temperature is within the suitable operating temperature range, it is recorded as a stable temperature. If the external temperature is outside the suitable operating temperature range, the temperature difference between the external temperature and the suitable operating temperature range is calculated and recorded as an ultra-stable temperature. The environmental statistical analysis unit calculates the duration of the stable temperature and the duration of the ultra-stable temperature.

[0019] The environmental statistical analysis unit compares the fluid pressure inside the metering device with the preset fluid pressure interval. If the fluid pressure is within the preset fluid pressure interval, it is recorded as a stable pressure. If the fluid pressure is outside the preset fluid pressure interval, the pressure difference between the fluid pressure and the preset fluid pressure interval is calculated and recorded as an over-limit pressure. The environmental statistical analysis unit calculates the duration of the stable pressure and the duration of the over-limit pressure.

[0020] The environmental statistical analysis unit calculates the difference between the internal temperature and the external temperature of the metering device to obtain the temperature difference. The environmental statistical analysis unit compares the temperature difference with the preset temperature difference threshold. If the temperature difference is less than or equal to the preset temperature difference threshold, it is recorded as a normal temperature difference. The environmental statistical analysis unit counts the duration of the normal temperature difference. If the temperature difference is greater than the preset temperature difference threshold, the difference between the temperature difference and the temperature difference threshold is calculated and recorded as an abnormal temperature difference. The environmental statistical analysis unit counts the duration of the abnormal temperature difference.

[0021] As a preferred embodiment of the present invention, the method for the environmental statistical analysis unit to analyze environmental interference factors is:

[0022] The environmental statistical analysis unit calculates the ratio of the duration of stable temperature to the duration of ultra-stable temperature, the ratio of the duration of stable pressure to the duration of excessive pressure, the ratio of the duration of normal temperature difference to the duration of abnormal temperature difference, records the calculated three sets of ratios, and sends the three sets of ratios to the maintenance cycle analysis unit.

[0023] As a preferred embodiment of the present invention, after the maintenance cycle analysis unit obtains the three sets of ratios, it corrects the maintenance record amount according to the ratios to obtain the corrected maintenance record amount. The maintenance cycle analysis unit obtains different maintenance thresholds according to the preset fluid type, and compares the corrected maintenance record amount with the maintenance threshold. If the corrected maintenance record amount is greater than or equal to the maintenance threshold, a maintenance signal is generated, and the maintenance signal includes the location and type of the metering equipment to be maintained. If the corrected maintenance record amount is less than the maintenance threshold, no response is made.

[0024] As a preferred implementation of the present invention, the method for the device management unit to verify the interconnection function of the metering device is:

[0025] The equipment management unit continuously monitors the signals of the metering equipment. When the signal of the metering equipment is lost, an equipment abnormality warning is generated, the location information corresponding to the missing metering equipment signal and the type of metering equipment are packaged as warning information, and the equipment abnormality warning is sent to the maintenance management unit.

[0026] As a preferred embodiment of the present invention, after the maintenance management unit obtains the maintenance signal, it counts the maintenance signal and generates a maintenance reminder at a fixed interval. When generating the maintenance reminder, the maintenance management unit extracts the location information in all maintenance signals and calculates the maintenance route. The maintenance management unit calculates the maintenance route in the following manner:

[0027] 1. Take the preset maintenance personnel starting point as the starting point in the map, and mark the locations of all metering equipment to be maintained and metering equipment that generates equipment abnormality warnings on the map;

[0028] 2. Calculate the amount of maintenance tasks that the maintenance personnel can complete in a single maintenance and record it as the maintenance quantity;

[0029] 3. Count the number of maintenance personnel, generate the number of maintenance routes based on the number of maintenance personnel, obtain the maintenance route with the shortest total path through the optimal path specification algorithm, the number of metering equipment to be maintained on each maintenance route does not exceed the maintenance number, and send the maintenance route to the maintenance personnel.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. In the present invention, when the metering equipment is maintained and managed, the metering equipment is no longer maintained at fixed-frequency maintenance intervals. Instead, the workload and working hours of the metering equipment are counted, and the usage of the metering equipment is analyzed based on the workload and working hours of the metering equipment. The usage is used as the basis for the maintenance of the metering equipment, thereby making the maintenance of the metering equipment more in line with the actual situation, and avoiding the problem of untimely maintenance or over-frequent maintenance due to usage differences, avoiding the operation errors of the metering equipment and reducing the maintenance cost of the metering equipment.

[0032] 2. In the present invention, when analyzing the usage of the metering device, not only the internal fluid of the metering device is analyzed, but also the external environment of the metering device is analyzed, and the environmental interference factors caused by environmental factors are fully combined to further improve the accuracy of the maintenance interval analysis of the metering device.

[0033] 3. In the present invention, when managing the maintenance work of the maintenance equipment, multiple metering equipment to be maintained are uniformly processed and the maintenance route is optimized through an intelligent algorithm, thereby improving the maintenance efficiency and reducing the maintenance cost.

[0036] Figure 2 It is a system flow chart of the present invention. DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] See also Figure 1 - Figure 2 As shown, a metering equipment maintenance management system based on data analysis includes an equipment management unit, a maintenance management unit, a maintenance cycle analysis unit, a usage statistics analysis unit and an environmental statistics analysis unit. Fixed metering equipment is generally installed on a pipeline to measure the amount of liquid or gas passing through. Since the number of fixed metering equipment is large and the metering equipment is frequently used, the metering equipment needs to be maintained to ensure the accuracy of the metering equipment. Therefore, when the metering equipment is used, the workload completed by the metering equipment is counted by using the statistics analysis unit. The statistical method for the workload completed by the metering equipment is:

[0040] Step 1: Number the metering equipment and upload the number to the cloud. After the maintenance or installation of the metering equipment is completed, the time is counted on the cloud according to the corresponding number and recorded as the total running time T;

[0041] Step 2: When the gas or liquid passes through the metering device, it measures and records it as the passing amount, and uploads the measured passing amount to the cloud in real time. The cloud accumulates the passing amount of the metering device and records it as the total passing amount L;

[0042] Step 3: When there is no gas or liquid passing through the inside of the measuring device, the time is counted and recorded as the static time, and all static times are accumulated and recorded as the total static time t;

[0043] Step 4: Use the statistical analysis unit to obtain the maintenance record quantity X of the measuring equipment through formula analysis, X = (aT-bt)L, where a and b are preset weight coefficients, and 0.8<b<a<1.0, and use the statistical analysis unit to send the maintenance record quantity to the maintenance cycle analysis unit.

[0044] The environmental statistical analysis unit detects the operating environment of the metering device, obtains the internal temperature and external temperature of the metering device through the temperature sensor, obtains the fluid pressure inside the metering device through the pressure sensor, and presets the fluid type by manual input. The environmental statistical analysis unit compares the external temperature of the metering device with the preset suitable operating temperature range. If the external temperature is within the suitable operating temperature range, it is recorded as a stable temperature. If the external temperature is outside the suitable operating temperature range, the temperature difference between the external temperature and the suitable operating temperature range is calculated and recorded as an ultra-stable temperature. The environmental statistical analysis unit calculates the duration of the stable temperature and the duration of the ultra-stable temperature.

[0045] The environmental statistical analysis unit compares the fluid pressure inside the metering device with the preset fluid pressure interval. If the fluid pressure is within the preset fluid pressure interval, it is recorded as a stable pressure. If the fluid pressure is outside the preset fluid pressure interval, the pressure difference between the fluid pressure and the preset fluid pressure interval is calculated and recorded as an over-limit pressure. The environmental statistical analysis unit calculates the duration of the stable pressure and the duration of the over-limit pressure.

[0046] The environmental statistical analysis unit calculates the difference between the internal temperature and the external temperature of the metering device to obtain the temperature difference. The environmental statistical analysis unit compares the temperature difference with a preset temperature difference threshold. If the temperature difference is less than or equal to the preset temperature difference threshold, it is recorded as a normal temperature difference. The environmental statistical analysis unit counts the duration of the normal temperature difference. If the temperature difference is greater than the preset temperature difference threshold, the difference between the temperature difference and the temperature difference threshold is calculated and recorded as an abnormal temperature difference. The environmental statistical analysis unit counts the duration of the abnormal temperature difference.

[0047] The environmental statistical analysis unit calculates the ratio of the duration of stable temperature to the duration of ultra-stable temperature, the ratio of the duration of stable pressure to the duration of excessive pressure, the ratio of the duration of normal temperature difference to the duration of abnormal temperature difference, and records the three groups of ratios as A, B, and C respectively, and sends the three groups of ratios to the maintenance cycle analysis unit.

[0048] After the maintenance cycle analysis unit obtains the three sets of ratios, it corrects the maintenance record amount according to the ratios and obtains the corrected maintenance record amount Y. The maintenance cycle analysis unit obtains different maintenance thresholds according to the preset fluid type, and compares the corrected maintenance record amount with the maintenance threshold. If the corrected maintenance record amount is greater than or equal to the maintenance threshold, a maintenance signal is generated. The maintenance signal includes the location and type of the metering equipment to be maintained. If the corrected maintenance record amount is less than the maintenance threshold, no response is made.

[0049] The equipment management unit conducts continuous signal monitoring of the metering equipment. When the signal of the metering equipment is lost, an equipment abnormality warning is generated, and the location information corresponding to the missing metering equipment signal and the type of metering equipment are packaged as warning information. The equipment abnormality warning is sent to the maintenance management unit. The maintenance management unit can add the metering equipment that generates the equipment abnormality warning to the maintenance route during maintenance.

[0050] Embodiment 2:

[0051] See also Figure 1 - Figure 2 As shown, after the maintenance management unit obtains the maintenance signal, it counts the maintenance signal and generates a maintenance reminder at a fixed interval. When generating the maintenance reminder, the maintenance management unit extracts the location information in all maintenance signals and calculates the maintenance route. The maintenance management unit calculates the maintenance route in the following manner:

[0052] 1. Take the preset maintenance personnel starting point as the starting point in the map, and mark the locations of all metering equipment to be maintained and metering equipment that generates equipment abnormality warnings on the map;

[0053] 2. Calculate the amount of maintenance tasks that the maintenance personnel can complete in a single maintenance and record it as the maintenance quantity;

[0054] 3. Count the number of maintenance personnel, generate the number of maintenance routes based on the number of maintenance personnel, obtain the maintenance route with the shortest total path through the optimal path specification algorithm such as the ant colony algorithm and the column generation algorithm, and the number of metering devices to be maintained on each maintenance route does not exceed the maintenance number. The maintenance route is sent to the maintenance personnel, who perform maintenance according to the maintenance route to improve maintenance efficiency.
