[0003] The replacement of meters cannot be replaced by machines and usually requires manual workers to go to the meter installation location to replace the meters. Many meters are installed in outdoor scattered areas, such as old residential areas. Newly recruited meter replacement workers need to spend a lot of time looking for the target meters because they are not familiar with the on-site environment, and even rely on old employees to lead the way, resulting in low meter replacement efficiency.

Detailed implementation manners

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to 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 used to limit the present invention.

[0019] An embodiment of the present application discloses a periodic meter replacement method. For meter replacement personnel who are not familiar with the terrain, the system designs an optimal path for the meter replacement personnel to perform meter replacement work along the optimal path. And when the meter replacement task location is in an old community, the system uses a meter quick positioning method to locate the meter to be replaced so that the meter replacement personnel can quickly find the meter. During the meter replacement process, the system will provide action guidance to the meter replacement personnel through the work order control terminal to ensure that the meter replacement personnel can quickly and correctly complete the detection of the new meter, the replacement of the old meter and the meter adjustment work. After the meter replacement is completed, the system will classify and recycle the old meters.

[0020] Refer to Figure 1 , a periodic meter replacement method includes the following steps: Step S1: Collect work order operation instructions from a preset work order operation terminal.

[0021] The work order operation terminal is a device carried by the meter replacement personnel, and the work order operation terminal can receive the meter replacement task sent by the device terminal.

[0022] The work order operation instruction refers to a task instruction assigned by the superior to the meter replacement personnel to go to a designated location for meter replacement operation.

[0023] The work order operation instruction is sent from the terminal to the work order operation terminal, so the work order operation instruction can be directly collected from the work order operation terminal.

[0024] Step S2: Retrieve all meter replacement task locations based on the work order operation instruction.

[0025] The meter replacement task location refers to the position point where meter replacement operation needs to be carried out. The work order operation instruction contains detailed task information of each meter replacement task, including information such as the meter replacement task location and the model of the meter to be replaced. Therefore, the meter replacement task location can be directly retrieved from the work order operation instruction.

[0026] Step S3: Connect all the meter replacement task locations in series by a preset optimal path planning method to form a meter replacement route.

[0027] The work order operation instruction contains multiple meter replacement tasks, so there are multiple meter replacement task locations. The meter replacement personnel need to go to each meter replacement task location to perform meter replacement operation. The meter replacement route is the movement route of the meter replacement personnel when performing meter replacement at each meter replacement task location.

[0028] To ensure the shortest moving route and improve the efficiency of meter replacement work, it is necessary to plan the moving route. The system uses the optimal path planning method for planning. The optimal path planning method will not be elaborated here and will be introduced in detail in the subsequent embodiments.

[0029] Step S4: Replace the meter along the meter replacement route, and identify the meter replacement task location from the preset urban planning information to determine whether the meter replacement task location is in an old community.

[0030] Urban planning information refers to the location distribution of each community and village in the city. The urban planning information is planned by the municipal department and is available for the public to view. This will not be elaborated here.

[0031] When replacing the meter, for relatively new communities, the overall distribution of equipment is relatively neat, the meter replacement operation is more convenient, and the efficiency is higher. For old communities, due to years of disrepair, the equipment is distributed messily, and meter replacement personnel may have difficulties in finding the meter, especially for new meter replacement personnel who are not familiar with the terrain and the installation location of the meters.

[0032] When the meter replacement personnel replace the meter along the meter replacement route, they need to first determine whether there is a meter replacement task location in the received meter replacement task that is in an old community. The method for determining whether the meter replacement task location is in an old community is to identify the meter replacement task location from the urban planning information.

[0033] Step S5: When the meter replacement task location is in the old community, use the preset meter quick positioning method to locate the specific installation location of the meter and replace the meter.

[0034] If the meter replacement task location is not in an old community, it is relatively simple to find the meter during the meter replacement operation, and the meter replacement is carried out according to the normal meter replacement process.

[0035] If the meter replacement task location is in an old community, due to the difficulty in finding the meter, at this time, use the meter quick positioning method to locate the meter in the old community for easy search, and then replace the meter. The meter quick positioning method will not be elaborated here and will be introduced in detail in the subsequent embodiments.

[0036] Refer to Figure 2 , the meter quick positioning method includes the following steps: Step S500: Collect meter fuzzy positioning information.

[0037] Meter fuzzy positioning information refers to the installation location of the meter to be replaced in the old community. The meter integrates a positioning chip, and the work order operation terminal can be wirelessly connected to the positioning chip of the old meter to be replaced, and collect the meter fuzzy positioning information in the positioning chip through the wireless connection.

[0038] Step S501: Determine the target fuzzy distance and the target height distance based on the instrument fuzzy positioning information and the device positioning information of the locator preset on the work order operation terminal.

[0039] The device positioning information refers to the positioning information of the work order operation terminal. There is a locator in the work order operation terminal, and the positioning information of the work order operation terminal can be determined through the locator.

[0040] The target fuzzy distance refers to the distance between the instrument to be replaced and the work order operation terminal. The target height distance refers to the height difference in the height direction between the instrument to be replaced and the work order operation terminal.

[0041] When the instrument fuzzy positioning information of the instrument to be replaced is determined and combined with the device positioning information of the locator on the work order operation terminal, the target fuzzy distance and the target height distance between the two can be determined according to the distance formula between two points.

[0042] Step S502: Match the basic frequency of the buzzer preset on the work order operation terminal based on the target fuzzy distance.

[0043] In this embodiment, a buzzer is integrated on the work order operation terminal, and the buzzer can produce different ways of beeping according to the distance change between the work order operation terminal and the old instrument to be replaced.

[0044] The basic frequency of beeping refers to the pitch of the buzzer when beeping. The basic frequency of beeping is inversely proportional to the target fuzzy distance. The smaller the target fuzzy distance, the higher the basic frequency of beeping, and at this time the sound of the buzzer is sharper.

[0045] Step S503: Determine the target floor difference based on the target height distance and the preset reference floor height.

[0046] The reference floor height is the standard height of a single floor of a general residential community building, which will not be elaborated here.

[0047] The target floor difference refers to the floor difference between the floor where the old instrument to be replaced is located and the floor where the meter replacement personnel is located. When the target height distance is determined, the target floor difference is the integer part of the quotient of the target height distance divided by the reference floor height.

[0048] Step S504: Match the interval beeping frequency of the buzzer based on the target floor difference.

[0049] The interval beeping frequency refers to the number of beeps of the buzzer per unit time. The interval beeping frequency of the buzzer is inversely proportional to the target floor difference. The smaller the target floor difference, it means that the meter replacement personnel is closer to the instrument to be replaced, and at this time the interval beeping frequency of the buzzer is greater.

[0050] Step S505: During the process that the meter replacement personnel approach the preset meter to be replaced, control the buzzer of the work order operation terminal to emit a beeping prompt at the beeping base frequency and the interval beeping frequency.

[0051] When the meter replacement personnel search for the meter to be replaced in the old community, the buzzer on the work order operation terminal will emit a beeping prompt. As the meter replacement personnel gradually approach the meter to be replaced, the beeping base frequency of the buzzer gradually increases, the sound becomes sharp, and the interval beeping frequency of the buzzer gradually becomes larger. Recently, the buzzer will emit continuous, rapid and sharp beeps, and the meter replacement personnel can judge whether they are approaching the meter to be replaced based on this.

[0052] Refer to Figure 3 , the meter quick positioning method further includes the following steps: Step S510: Retrieve the location operation report from the work order operation terminal based on the meter replacement task location.

[0053] In this embodiment, when the staff perform daily maintenance on the meter, they need to record the maintenance process to form an operation report. The operation report records the process of this maintenance and, when the meter is not easy to find, records the specific location of the meter and the recognizable object features at this location, etc., so that the next operator can view the record and search for the meter. The operation includes being recorded in the work order operation terminal. The location operation report is the daily operation report of the meter at the meter replacement task location. The location operation report can be directly retrieved by inputting the keyword of the meter replacement task location in the work order operation terminal.

[0054] Step S511: Retrieve the meter location marking features from the location operation report, where the meter location marking features include a first feature and a second feature.

[0055] The meter location marking features refer to the indicative signs that can clearly indicate the location at the meter installation location. For example, if there is an electrical cabinet above the meter installation location, the electrical cabinet is the meter location marking feature that can clearly indicate the meter installation location. In this embodiment, the meter location marking features include at least two features, namely the first feature and the second feature, and these features are all recorded in the location operation report, so the meter location marking features can be directly retrieved from the location operation report.

[0056] Step S512: During the process that the meter replacement personnel approach the preset meter to be replaced, collect the environmental images of the travel route.

[0057] The environmental images of the travel route refer to the images on the moving route when the meter replacement personnel move in the old community and search for the meter to be replaced. There is a camera on the work order operation terminal. When the meter replacement personnel move, the camera will take pictures of the images on the personnel moving route in real time.

[0058] Step S513: Determine whether the first feature exists in the traveling route environment image.

[0059] In this embodiment, the environment is recognized by a camera. When both the first feature and the second feature are detected and the buzzer is in the situation of step S505, it indicates that the meter replacement personnel have reached the meter replacement task location. With the first feature and the second feature, it is possible to assist in determining whether the accurate position has been reached.

[0060] When making a judgment based on the instrument position marking feature, first judge the first feature, and then judge the second feature.

[0061] Step S514: When the first feature exists in the traveling route environment image, continue to determine whether the second feature exists in the traveling route environment image.

[0062] When the first feature can be recognized in the traveling route environment image, it cannot be completely determined at this time that the personnel have reached the destination. There may be the same first feature at other positions. At this time, it is still necessary to continue to identify whether the second feature exists.

[0063] Step S5141: When the second feature exists in the traveling route environment image, control the buzzer of the work order operation terminal to emit a beeping prompt.

[0064] If the second feature is simultaneously recognized in the traveling route environment image, that is, both the first feature and the second feature exist, it indicates that the personnel have reached the meter replacement task location. At this time, the buzzer will also beep according to the situation of step S505 to prompt that the meter replacement personnel have reached the designated position.

[0065] In this embodiment, the effect of first recognizing the second feature and then the first feature is the same as that of the above embodiment, and will not be elaborated here.

[0066] Refer to Figure 4 , the instrument quick positioning method further includes the following steps: Step S5142: When the second feature does not exist in the traveling route environment image, determine whether the target fuzzy distance falls within the preset meter installation range.

[0067] For the judgment result of step S514, if the second feature does not exist in the traveling route environment image, there may be two situations. One situation is that the personnel have not reached the meter replacement task location. The second situation is that the second feature may be covered, and it is necessary to judge which of the above situations it is.

[0068] Due to the positional error of the locator, it is impossible to accurately locate a fixed point, but it can roughly determine that it is within a certain position range. The instrument installation range is the position range where the instrument is set by the technician. The instrument installation range is a spherical area, which will not be elaborated here.

[0069] The distance between the meter-changing personnel and the meter to be replaced is the target fuzzy distance. Therefore, by judging the positional relationship between the target fuzzy distance and the instrument installation range, it is possible to determine whether there may be a second feature at this position.

[0070] Step S51421: When the target fuzzy distance falls within the instrument installation range, retrieve the relative position of the second feature with respect to the first feature from the location operation report.

[0071] If the target fuzzy distance does not fall within the instrument installation range, it is very likely that there is no second feature at this position, and the personnel have not reached the meter-changing task location.

[0072] If the target fuzzy distance falls within the instrument installation range, there may be a second feature at this position. The specific location of the second feature can be retrieved from the location operation report, and the relative position between the second feature and the first feature is recorded in the report.

[0073] Step S51422: Identify the relative position from the traveling route environment image to determine whether there is an occlusion.

[0074] By judging whether there is an occlusion at the relative position, it is determined whether the second feature is occluded by the occlusion.

[0075] By performing image recognition on the relative position from the traveling route environment image, if there is an object at the relative position, the object is the occlusion.

[0076] Step S51423: When there is the occlusion, the work order operation terminal issues a prompt to drive the meter-changing personnel to handle the occlusion and re-judge whether there is the second feature at the relative position in the traveling route environment image.

[0077] When the camera recognizes an object defined as an occlusion, the work order operation terminal will issue a prompt message to notify the meter-changing personnel to move the occlusion at the relative position. After the occlusion is removed, the camera re-recognizes the relative position after the occlusion is removed and re-judges whether there is a second feature.

[0078] Step S51424: When there is the second feature, the work order operation terminal issues a beeping prompt to drive the meter-changing personnel to set a prompt nameplate at the relative position.

[0079] If a second feature is recognized in the relative position, it proves that the meter replacement personnel have arrived at the meter replacement task location. The work order operation terminal will issue a prompt, indicating that the meter replacement personnel have reached the destination, and prompting the meter replacement personnel to set a prompt nameplate at the relative position. The prompt nameplate is used to prompt the surrounding personnel not to place items at this location to avoid blocking the meter position marking feature and reducing the maintenance efficiency of the staff.

[0080] Refer to Figure 5 , the meter replacement method includes the following steps: Step S520: Before replacing the meter, collect the image information of the old meter.

[0081] The image information of the old meter refers to the image of the old meter taken by the camera of the work order operation terminal before the old meter is disassembled.

[0082] After the meter replacement personnel arrive at the meter replacement task location and before disassembling the old meter, first take a picture of the old meter through the camera of the work order operation terminal.

[0083] Step S521: Identify the old meter from the old meter image information to determine the old meter model information, and determine the meter iteration series range based on the old meter model information.

[0084] The old meter model information refers to the model of the old meter to be replaced. There is a barcode containing the meter model on the meter. The old meter model information can be obtained by identifying the barcode from the old meter image information.

[0085] When replacing the old meter, a meter of the same model or a meter of the same series with a newer version needs to be installed. The meter iteration series range refers to the range of models of new meters that can be used to replace the old meter. The meter iteration series range can be determined based on the old meter model information.

[0086] Step S522: Retrieve the new meter model information from the work order operation instruction.

[0087] The new meter model information refers to the model of the new meter specified by the terminal for replacing the old meter. The new meter model information is included in the work order operation instruction, and the new meter model information can be directly retrieved from the work order operation instruction.

[0088] Step S523: When the new meter model information falls within the meter iteration system range, collect the new meter image information.

[0089] The new meter image information refers to the image taken of the new meter used to replace the old meter through the camera.

[0090] If the new meter model information does not fall within the meter iteration system range, it means that the new meter shipped for replacing the old meter is incorrect, and re-stocking is required.

[0091] If the new meter model information falls within the range of the meter iteration system, it means that the model of the new meter specified and sent by the terminal is correct and can be used to replace the old meter. At this time, before replacing the old meter, it is also necessary to take a photo of the new meter to determine whether the surface of the new meter is damaged.

[0092] Step S524: Compare the new watch image information with a preset reference meter to determine whether the surface of the new watch is damaged.

[0093] The reference instrument refers to the image of a standard instrument with an intact surface, which is used for comparison with the damaged instrument and will not be described in detail here.

[0094] By comparing the image information of the new meter with the reference meter, if there is no difference between the two, it means that the surface of the new meter is not damaged and can be used to replace the old meter. If there is a difference between the two, the surface of the new meter is damaged. In this case, the new meter cannot be used to replace the old meter and needs to be re-delivered.

[0095] Step S525: When the surface of the new meter is not damaged, the work order operation terminal is controlled to connect to the new meter and perform a functional self-check of the new meter.

[0096] After confirming that the new meter surface is intact, the function of the new meter needs to be tested to determine whether the new meter functions properly. The meter has a self-checking function. After connecting the new meter through the work order operation terminal, the work order operation terminal can control the new meter to perform a functional self-check.

[0097] If it is confirmed that the new watch model matches, the surface is intact and the functions are normal, the new watch can be used to replace the old watch.

[0098] Reference Figure 6 After the new meter has completed the self-test, the new meter and the old meter are replaced. The replacement steps include the following steps: In this embodiment, during the instrument replacement process, the instrument replacement must be performed by a person designated by the system to replace the instrument, and the steps of replacing the instrument must be performed in a designated order.

[0099] Step S530: After completing the functional self-check, control the work order operation terminal to collect the facial image of the processing personnel, and retrieve the facial image of the delegated personnel from the work order operation instruction.

[0100] The facial image of the processing personnel refers to the facial image of the person changing the watch collected by the camera integrated in the work order operation end.

[0101] The face image of the assigned personnel refers to the facial image of the personnel assigned by the system to perform the meter replacement work. The facial image of each meter replacement personnel is recorded in the system. When assigned to perform the meter replacement work, the face image of the assigned personnel can be directly retrieved from the work order operation instruction. By judging whether the face image of the processing personnel is consistent with the face image of the assigned personnel, it is determined whether the meter replacement is carried out by the person himself, so as to avoid illegal operations.

[0102] Step S531: When the face image of the processing personnel is consistent with the face image of the assigned personnel, retrieve the operation guidance instruction from the work order operation terminal based on the new meter model information.

[0103] If the two are inconsistent, the work order operation terminal will issue a prompt and report it to the terminal for review.

[0104] If the face image of the processing personnel is consistent with the face image of the assigned personnel, it means that the identity of the meter replacement personnel can be corresponding. At this time, the meter replacement personnel retrieve the operation guidance instruction from the work order operation terminal according to the process. The operation guidance instruction refers to the guidance instruction of the operation specification steps for the replacement process of a specific model of instrument issued by the work order operation terminal, which is used to guide the meter replacement personnel to replace the meter. The work order operation terminal stores the operation guidance instructions for each model of instrument. By inputting the new meter model information into the work order operation terminal, the corresponding operation guidance instruction can be retrieved.

[0105] Step S532: The work order operation terminal issues a guidance prompt according to the operation guidance instruction to guide the meter replacement personnel to follow and synchronously replace, and collect the personnel action images.

[0106] The personnel action image refers to the image of the meter replacement action of the meter replacement personnel during the process of replacing the meter collected by the camera.

[0107] During the process of the meter replacement personnel following the operation guidance instruction to replace the meter, the camera will take pictures of the actions of the meter replacement personnel in real time to ensure the standardization of the meter replacement actions.

[0108] Step S533: Match the preset reference meter replacement action based on the operation guidance instruction.

[0109] The reference meter replacement action refers to the standard action of the operation specification steps for meter replacement, and the reference meter replacement action is in the form of an image. By matching the operation guidance instruction with the preset action database, the reference meter replacement action can be matched. The action database is a database pre-entered into the system by technical personnel, which contains the one-to-one correspondence between the operation guidance instruction and the reference meter replacement action.

[0110] After the reference meter replacement action is matched, comparing the personnel action image with the reference meter replacement action can determine whether the action steps of the meter replacement personnel during the meter replacement process meet the specifications.

[0111] Step S534: When the personnel action image is inconsistent with the reference meter replacement action, issue a warning prompt and count the number of errors.

[0112] If the personnel action image is consistent with the reference meter replacement action, it meets the specifications.

[0113] If the two are inconsistent, it means that the meter replacement personnel did not replace the meter according to the specified meter replacement action steps. If the action is not standardized, it may cause the meter to malfunction. When the above situation occurs, the work order operation terminal will issue a warning prompt and count the number of non-standard meter replacement actions of the meter replacement personnel, allowing the meter replacement personnel to correct within a reasonable number of errors.

[0114] Step S535: When the count of the number of errors is greater than 2, mark the meter replacement task location as an abnormal operation location and upload it to the terminal.

[0115] The abnormal operation location refers to the location where there is an abnormality in the meter replacement process. Within the allowable number of error range, that is, when the count of the number of errors is not greater than 2, the abnormal operation behavior of the meter replacement personnel is not pursued. If the count of the number of errors is greater than 2, it means that there are other abnormal operations by the meter replacement personnel during the meter replacement process, resulting in a relatively large count of the number of errors. At this time, the system will mark the meter replacement task location at this place, define it as an abnormal operation location and upload it to the terminal, and subsequent relevant inspectors will conduct inspections.

[0116] Refer to Figure 7 , the meter reading method includes the following steps: In this embodiment, meter reading is required when replacing the new meter and the old meter, that is, record the reading value of the old meter before the old meter is removed, and then after the new meter is installed, make the reading values of the new meter correspond to those of the old meter one by one.

[0117] Step S540: Identify the preset reading features from the old meter image information to determine the old meter reading for meter reading.

[0118] The old meter reading for meter reading refers to the reading value displayed on the old meter to be replaced, which is the cumulative reading value of the electricity or water volume accumulated by the user.

[0119] In step S520, the old meter image information is collected. The old meter image information contains reading features. Therefore, the old meter reading for meter reading can be obtained by performing image recognition on the reading features from the old meter image information.

[0120] Step S541: Match the initial meter reading of the corresponding new meter based on the old meter reading for meter reading.

[0121] After the new meter replaces the old meter, it is necessary to adjust the reading of the new meter so that the reading of the new meter is consistent with that of the old meter. The initial meter reading is the target reading that the new meter needs to be adjusted to. Before and after the replacement of the old meter and the new meter, the readings of the two must be the same. Therefore, the meter reading of the old meter is consistent with the initial meter reading.

[0122] Step S542: Based on the initial meter reading, control the work order operation terminal to issue a meter adjustment prompt, and control the work order operation terminal to connect to the new meter to collect the actual meter adjustment reading of the new meter.

[0123] After determining the initial meter reading of the new meter, the work order operation terminal will issue a meter adjustment prompt to prompt the meter replacement personnel to adjust the new meter.

[0124] The actual meter adjustment reading refers to the reading that the meter replacement personnel actually adjust for the new meter. After completing the meter adjustment, the meter replacement personnel need to connect to the new meter through the work order operation terminal. At this time, the work order operation terminal will collect the actual meter adjustment reading of the new meter.

[0125] Step S543: Determine whether the actual meter adjustment reading is consistent with the initial meter reading.

[0126] When the meter replacement personnel operate abnormally, the actual meter adjustment reading may not be consistent with the initial meter reading. To ensure the consistency of the two, the system needs to judge the actual meter adjustment reading and the initial meter reading.

[0127] Step S5431: When the actual meter adjustment reading is consistent with the initial meter reading, upload the actual meter adjustment reading to the terminal.

[0128] If the readings of the two are consistent, it means that the meter replacement personnel operate normally. At this time, the work order operation terminal will upload the actual meter adjustment reading to the terminal.

[0129] Step S5432: When the actual meter adjustment reading is not consistent with the initial meter reading, the work order operation terminal issues a re-adjustment prompt and counts the number of adjustment times.

[0130] If the readings of the two are not consistent, it means that the meter replacement personnel have abnormal actions during the meter adjustment process, resulting in a deviation in the actual meter adjustment reading. In the above situation, the work order operation terminal will issue a re-adjustment prompt to prompt the meter replacement personnel to re-adjust the reading of the new meter, and the system will count the number of re-adjustments of the meter replacement personnel.

[0131] Step S54321: When the counted number of the adjustment times is greater than 2, mark the meter replacement task location as an abnormal operation location and upload it to the terminal.

[0132] Within the allowable number of adjustment times, that is, when the counted number is not greater than 2, the abnormal operation behavior of the meter replacement personnel will not be pursued.

[0133] If the counting times of the adjustment times are greater than 2, it indicates that the meter replacement personnel have repeated abnormal operations multiple times. At this time, the system will mark the location of the meter replacement task as an abnormal operation location and upload it to the terminal, and relevant inspectors will conduct inspections later.

[0134] After the meter replacement is completed, the old meter is recycled. The old meter recycling method includes the following steps: Step S550: Determine the attribution category of the old meter based on the old meter model information.

[0135] After the old meter to be replaced is replaced, the replaced old meter needs to be recycled. When recycling the old meter, it will be classified and bagged according to the model of the old meter, so that each bag contains old meters of the same model or the same series. The attribution category of the old meter is the classification category to which the replaced old meter belongs. The attribution category of the old meter corresponds one-to-one with the old meter model information, and each old meter model information corresponds to one attribution category of the old meter.

[0136] Step S551: Classify the replaced and disassembled old meters based on the attribution category of the old meter to obtain a recycling pile of the same series.

[0137] The recycling pile of the same series refers to the old meters of the same model series after classification.

[0138] Step S552: Identify the damaged type of the old meter from the old meter image information.

[0139] In this embodiment, when recycling the old meter, in addition to classifying and recycling according to the model, the old meters of the same model also need to be classified according to the damaged type. The damaged type can be identified and determined from the old meter image information.

[0140] Step S553: Reclassify the old meters in the recycling pile of the same series based on the damaged type to obtain different damaged piles.

[0141] The different damaged piles refer to the results of classifying the old meters of the same series model according to the damaged type. Classifying the old meters in the recycling pile of the same series according to the damaged type again can obtain different damaged piles.

[0142] Step S554: Piece together the different damaged piles with each other to obtain complete old meters and incomplete old meters.

[0143] The complete old meter refers to an old meter with a complete surface and no damage. The incomplete old meter refers to an old meter with a damaged surface.

[0144] Since the different damaged piles are all meters of the same series and the damaged parts of each different damaged pile are different, disassembling and reorganizing the old meters of two different damaged piles can obtain a part of the old meters with an undamaged surface and another part of the incomplete old meters with more damage.

[0145] Step S555: Recycle the complete old table and the incomplete old table separately.

[0146] The complete old table and the incomplete old table generated by recombination are recycled separately and have different uses.

[0147] The optimal path planning method includes the following steps: Step S30: Determine the number of locations of all the meter replacement task locations from the work order operation instructions.

[0148] The number of locations refers to the total number of meter replacement task locations included in each work order operation instruction. After retrieving the meter replacement task locations from the work order operation instructions and counting the number of all the meter replacement task locations, the number of locations can be obtained.

[0149] Step S31: Based on the number of locations and the preset number of new meters carried each time, determine the number of times of returning to the preset meter transfer station location to pick up meters.

[0150] The number of carried refers to the maximum number of new meters that the meter replacement personnel can carry each time for the meter replacement task. The number of carried is a reference value set by the technical personnel and will not be elaborated here.

[0151] When the new meters carried by the meter replacement personnel are used up, the meter replacement personnel need to go to the nearest meter transfer station location to obtain new meters. The meter transfer station location is used to store new meters and recycle old meters.

[0152] The number of times of returning to pick up meters refers to the number of times that the meter replacement personnel need to return to the meter transfer station location to obtain new meters when completing the meter replacement work at all the meter replacement task locations. The number of times of returning to pick up meters is the quotient of the number of locations and the number of carried.

[0153] Step S32: Based on all the meter replacement task locations and the meter transfer station location, determine the meter pick-up distance between each meter replacement task location and the meter transfer station location.

[0154] The meter pick-up distance refers to the distance between the meter replacement task location and the meter transfer station location. When the meter replacement task location and the meter transfer station location are determined, the meter pick-up distance between the two locations can be determined according to the distance formula between two points.

[0155] Step S33: Sort each meter replacement task location from near to far based on the meter pick-up distance, and screen out the meter replacement task locations based on the number of times of returning to pick up meters, and define them as return locations.

[0156] Without considering the movement order of the meter replacement personnel between adjacent meter replacement task locations, in order to minimize the path traveled by the meter replacement personnel when completing all meter replacement task locations, that is, to require the minimum meter-taking distance at the meter replacement task location where re-pickup occurs each time. Therefore, the meter-taking distances of each meter replacement task location are sorted in ascending order, and several minimum meter-taking distances are selected from the sorting according to the number of meter-taking times determined in step S31. The meter replacement task locations corresponding to these several meter-taking distances are defined as the return locations, that is, the meter replacement personnel just use up the new meters at these meter replacement task locations and return to the instrument transfer station location to pick up goods.

[0157] Step S34: Connect all the meter replacement task locations in series and pick up meters for return at the return locations.

[0158] After determining the return locations, connect all the meter replacement task locations in the way with the shortest adjacent distance, and make the meter replacement personnel just be at the return locations when using up the new meters. The path obtained at this time is the optimal path.
