[0002] An intelligent electricity meter is one of the basic devices for data collection in the smart grid, undertaking the tasks of collecting, measuring, and transmitting original electricity data, and serving as the basis for information integration, analysis and optimization, and information display.

[0003] Intelligent electricity meters are commonly used in various electricity consumption scenarios where electricity meters are scattered, such as various villa areas, commercial centers, industrial parks, and public buildings. With the advantages of simple and convenient installation, no need for wiring, no need for additional acquisition equipment, no installation distance limitation, and remote management of electricity consumption through a direct connection meter reading system, they are welcomed by many users, greatly saving the labor installation and supporting costs and improving the electricity consumption management efficiency.

[0004] With the popularization of intelligent electricity meters, in remote areas or areas where the application scope of intelligent electricity meters is not wide, when an intelligent electricity meter fails, on the one hand, the local electricity consumption safety cannot be guaranteed, and on the other hand, the cost for the supplier to dispatch staff for maintenance is relatively high. Therefore, a set of intelligent electricity meter maintenance strategies is needed to minimize the impact on local electricity consumption and reduce the enterprise's maintenance cost as much as possible when the electricity meter fails.

[0056] When the maintenance cycle D is equal to the maximum failure cycle, then the quantity coefficient K ≥ 2;

[0057] When the maintenance cycle D is greater than the maximum failure cycle, then the quantity coefficient K ≥ 1;

[0058] Then,

[0066] Then the failure cycle of the smart meters in the smart meter module is L / H.

[0067] The present invention has the following beneficial effects:

[0068] 1. The industrial equipment control method and system based on the Internet of Things set up an intelligent electricity meter module. The intelligent electricity meter module includes one or more electricity meter modules. In one electricity meter module, one intelligent electricity meter and one intelligent switch are connected in series, and each electricity meter module in the intelligent electricity meter module is connected in parallel. When the intelligent electricity meter fails, the device uses Internet of Things technology to control the intelligent switch and replaces the faulty intelligent electricity meter with a usable intelligent electricity meter to ensure electricity safety. At the same time, an intelligent electricity meter module is set up for areas without maintenance sites. Using multiple intelligent electricity meters can delay the maintenance cycle of the maintenance personnel for the intelligent electricity meters, reduce the number of trips of the maintenance personnel to repair the intelligent electricity meters, and reduce the cost of the intelligent electricity meter supplier to repair the intelligent electricity meters.

[0069] 2. The industrial equipment control method and system based on the Internet of Things add a destination. Set the range radius R of the destination to control the range between the selected devices. Draw a circle with the position coordinates of the selected devices as the center and the range radius as the radius. Each time, select the circle with the most devices between the devices and assign the devices between the circles to one destination. In this way, the originally multiple device rooms that need to be repaired are streamlined into the fewest destinations, thereby reducing the number of position coordinates to be calculated and greatly reducing the workload in the later planning of the maintenance path.

[0070] 3. The industrial equipment control method and system based on the Internet of Things set the standard quantity F of the repaired intelligent electricity meters and the average maintenance threshold B. When the total quantity of the faulty intelligent electricity meters is less than the standard quantity F or the average maintenance cost is greater than the average maintenance threshold B, no maintenance personnel are dispatched to repair the intelligent electricity meters, adding conditions for maintenance and reducing unnecessary maintenance, which can greatly reduce the cost of the intelligent electricity meters.

[0071] 4. The industrial equipment control method and system based on the Internet of Things calculate the failure cycle of the intelligent electricity meters in each intelligent electricity meter module and calculate the maintenance cycle. Under normal circumstances, every time a maintenance cycle arrives, it is judged whether to dispatch maintenance personnel to repair based on the total quantity of the faulty intelligent electricity meters and the average maintenance cost. The existence of the maintenance cycle, on the one hand, plans the time for repairing the intelligent electricity meters, making the maintenance more planned and improving the maintenance efficiency. On the other hand, when the maintenance personnel repair the intelligent electricity meters each time, when the devices are working normally, the proportion of the faulty intelligent electricity meters in the total number of all intelligent electricity meters is the largest. Under the condition of coordinating the maintenance cost, the different numbers of electricity meters equipped for each enterprise can be used as much as possible, and the sum of the travel expenses for maintenance and the expenses for repairing the intelligent electricity meters is the lowest, and the maintenance cost is the lowest.

[0072] 5. The industrial equipment control method and system based on the Internet of Things calculate the number of smart meters in the smart meter module through the maintenance cycle and the failure cycle of the smart meters in the smart meter module. At the same time, a quantity coefficient K is added to ensure that in general, within one maintenance cycle, all the smart meters in the smart meter module will not fail, and there is no need to immediately dispatch maintenance personnel to repair the smart meters, reducing the maintenance cost and ensuring the safety of power consumption.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

There is only one smart meter in use in the smart meter module, and the smart meter module is installed in the equipment room;

[0080] An information collector, which collects the data of the smart meter, processes the data, and uses wireless communication technology to transmit the processed data to a remote server. The remote server receives the data and determines whether the smart meter is faulty.

[0082] The city where the equipment room is located is recorded as a region. When the smart meter supplier does not set up a maintenance site in a city, there is no maintenance site in the area where the equipment room is located.

[0083] When there is no maintenance site in the area where the equipment room is located, the equipment room is configured with a smart meter module. When the smart meter in use in the smart meter module fails,

[0084] If there are other available smart meters, use the Internet of Things to remotely control the smart switch and replace the faulty smart meter with an available smart meter;

[0085] If there are no other available smart meters, dispatch maintenance personnel to repair the smart meter;

[0086] According to the data uploaded by the information collection module, obtain the number of faulty smart meters in the smart meter module, the location coordinates of the equipment room, and the location coordinates of the maintenance site, and adopt a maintenance strategy to repair the smart meter.

[0087] The statement that if there are other available smart meters, use the Internet of Things to remotely control the smart switch and replace the faulty smart meter with an available smart meter includes:

[0088] The meter module is composed of a smart meter and a smart switch connected in series;

[0089] Multiple meter modules are connected in parallel with each other;

[0090] As Figure 1 shown, the meter modules in the smart meter module are connected in parallel in the circuit, and the smart meter and the smart switch are connected in series to form a meter module.

[0091] When using a certain meter module, turn on the smart switch in the meter module.

[0092] By setting the smart meter module, the smart meter module includes one or more meter modules. In one meter module, a smart meter and a smart switch are connected in series, and each meter module in the smart meter module is connected in parallel. When the smart meter fails, the device uses Internet of Things technology to control the smart switch and replaces the faulty smart meter with an available smart meter to ensure power safety. At the same time, a smart meter module is set for the area without a maintenance site. Using multiple smart meters can delay the maintenance cycle of the maintenance personnel for the smart meter, reduce the number of trips of the maintenance personnel to repair the smart meter, and reduce the cost of the smart meter supplier to repair the smart meter.

[0093] The statement that according to the data uploaded by the information collection module, obtain the number of faulty smart meters in the smart meter module, the location coordinates of the equipment room, and the location coordinates of the maintenance site, and adopt a maintenance strategy to repair the smart meter includes:

[0094] Determine the destination. A destination includes one or more equipment rooms. Let the range radius of the destination be R, and the area included in the circle with the range radius R as the radius is a destination;

[0095] S1. Obtain the locations of the equipment rooms where the smart meter modules of all malfunctioning smart meters are located, and obtain a set of equipment room locations, denoted as the first location, the second location... the Nth location respectively.

[0096] For example Figure 2 In this embodiment, 1 is the first location, 2 is the second location, 3 is the third location, 4 is the fourth location, 5 is the fifth location, and 6 is the sixth location. The positional relationship is as shown in the figure. Among them, the one numbered 0 is the maintenance site.

[0097] S2. Taking each equipment room location coordinate in the set of equipment room locations as the center, draw a circle with a radius of R, count the number of equipment rooms in each circle, obtain the circle with the largest number of equipment rooms included, and assign all the equipment rooms within this circle to one destination.

[0098] When there are multiple circles with the same number of equipment rooms included, arbitrarily select one of the circles, and assign all the equipment rooms within this circle to one destination.

[0099] The equipment room locations located in the destination are recorded as registered locations.

[0100] S3. Remove the elements of the registered locations from the set of equipment room locations.

[0101] S4. Repeat S2 - S3 until the set of equipment room locations is an empty set.

[0102] For example Figure 2 As shown, in this embodiment, the set of equipment room locations is {1, 2, 3, 4, 5, 6}, the range radius is 2 km. Taking each equipment room location coordinate in the set of equipment room locations as the center, draw a circle with a radius of R, obtain the circle with the largest number of equipment rooms included. The circle with the first location as the center coordinate includes the equipment rooms corresponding to the three locations of 1, 4, and 5. The circle with the fourth location as the center coordinate includes the equipment rooms corresponding to the three locations of 1, 4, and 5, and the circle with the fifth location as the center coordinate includes the equipment rooms corresponding to the three locations of 1, 4, and 5. Select the circle with the first location as the center coordinate. The equipment rooms included in this circle are the equipment rooms corresponding to the first location, the fourth location, and the fifth location. Assign the equipment rooms corresponding to the first location, the fourth location, and the fifth location to the first destination.

[0103] Meanwhile, the first position, the fourth position, and the fifth position are marked as registered positions. The elements of the registered positions are removed from the set of equipment room positions, and the set of equipment room positions becomes {2, 3, 6}. Taking each equipment room position coordinate in the set of equipment room positions as the center and R as the radius to draw a circle, the circle containing the largest number of equipment rooms is obtained. The circle with the second position as the center coordinate contains the equipment rooms corresponding to the two positions of 2 and 6, and the circle with the sixth position as the center coordinate contains the equipment rooms corresponding to the two positions of 2 and 6. Select the circle with the second position as the center coordinate. The equipment rooms contained in this circle are the equipment rooms corresponding to the second position and the sixth position. The equipment rooms corresponding to the second position and the sixth position are assigned to the second destination;

[0104] Meanwhile, the second position and the sixth position are marked as registered positions. The elements of the registered positions are removed from the set of equipment room positions, and the set of equipment room positions becomes {3}. Taking each equipment room position coordinate in the set of equipment room positions as the center and R as the radius to draw a circle, the circle containing the largest number of equipment rooms is obtained. The circle with the third position as the center coordinate contains the equipment room corresponding to the 3 position. The equipment rooms within this circle are assigned to the third destination.

[0105] Meanwhile, the third position is marked as a registered position. The elements of the registered positions are removed from the set of equipment room positions, and the set of equipment room positions becomes an empty set.

[0106] S5. Obtain all destinations, record the center coordinates of each destination, and denote them as the first destination coordinate, the second destination coordinate... the Nth destination coordinate in sequence;

[0107] In this embodiment, denote the center coordinate of the first destination as the first destination coordinate, the center coordinate of the second destination as the second destination coordinate, and the center coordinate of the third destination as the third destination coordinate, as Figure 2 shown.

[0108] By adding destinations, setting the range radius R of the destination, controlling the range of the selected equipment rooms, taking the position coordinates of the selected equipment rooms as the center and the range radius as the radius to draw a circle, and each time selecting the circle containing the largest number of equipment rooms, and attributing the equipment rooms in the circle to one destination. In this way, the originally multiple equipment rooms that need to be repaired are streamlined into the destination with the smallest number, thereby reducing the number of calculated position coordinates and greatly reducing the workload in the later planning of the repair path.

[0109] According to the data uploaded by the information collection module, obtain the number of faulty smart meters in the smart meter module, and count the total number of faulty smart meters in all destinations.

[0110] According to the center coordinates of each destination, the total number of faulty smart meters in all destinations, and the position coordinates of the repair site, plan the repair path.

[0111] Plan the maintenance path:

[0112] S6: Starting from the maintenance site, randomly select the center coordinates of one destination as the first arrival location, and use the center coordinates of the unselected destinations as the first candidate locations;

[0113] S7: Randomly select the center coordinates of one destination from the first candidate locations as the second arrival location, and use the center coordinates of the unselected destinations as the second candidate locations;

[0114] S8: Randomly select the center coordinates of one destination from the second candidate locations as the third arrival location, and use the center coordinates of the unselected destinations as the third candidate locations. In this way, traverse the center coordinates of all destinations and return to the maintenance site to obtain multiple maintenance paths;

[0115] Calculate the path lengths of all maintenance paths;

[0116] Select the one with the minimum path length as the optimal maintenance path;

[0117] Calculate the maintenance cost according to the optimal maintenance path.

[0118] As Figure 2 shown, in this embodiment, the maintenance paths are the distances of 0 - 1 - 2 - 3 - 0, 0 - 1 - 3 - 2 - 0, 0 - 2 - 1 - 3 - 0, 0 - 2 - 3 - 1 - 0, 0 - 3 - 1 - 2 - 0, and 0 - 3 - 2 - 1 - 0.

[0119] Calculating the maintenance cost according to the optimal maintenance path includes:

[0120] Obtain the total number of faulty smart meters at all destinations, denoted as M;

[0121] As Figure 2 , in this embodiment, the number of smart meters to be repaired at each destination is obtained through the information collection module. The number of smart meters to be repaired at the first destination is 4, the number of smart meters to be repaired at the second destination is 3, and the number of smart meters to be repaired at the third destination is 1. The total number of smart meters to be repaired at all destinations is counted as M, then M = 8.

[0122] Calculate the maintenance cost and determine whether to dispatch maintenance personnel for repair,

[0123] Denote the path length of the optimal maintenance path as T, the cost per unit path length as C, and calculate the path cost of the optimal maintenance path as T * C;

[0124] Calculate the average maintenance cost of the faulty smart meters, denoted as A, A = (T * C) ÷ M;

[0125] Let the standard number of smart meters to be repaired be F.

[0126] If the total number M of faulty smart meters is less than the standard number F, no repair personnel are dispatched to repair the smart meters.

[0127] If the total number M of faulty smart meters is greater than or equal to the standard number F, let the average repair threshold of the smart meters be B.

[0128] When the average repair cost A is greater than the average repair threshold B, then no repair personnel are dispatched for repair.

[0129] When the average repair cost A is less than or equal to the average repair threshold B, then repair personnel are dispatched for repair.

[0130] By setting the standard number F of smart meters to be repaired and the average repair threshold B, when the total number of faulty smart meters is less than the standard number F or the average repair cost is greater than the average repair threshold B, no repair personnel are dispatched to repair the smart meters, and by adding repair conditions, the cost of smart meters can be greatly reduced.

[0131] Calculating the failure period of the smart meters in each smart meter module includes:

[0132] Obtaining the time when the smart meter module is assembled in the equipment room;

[0133] Obtaining the time of the most recent failure of the smart meters in the smart meter module;

[0134] Calculating the time interval between the time when the smart meter module is assembled and the time of the most recent failure of the smart meters in the smart meter module, denoted as time period L;

[0135] Counting the number of faulty smart meters in the smart meter module during this time period, denoted as H;

[0136] Then the failure period of the smart meters in the smart meter module is L / H.

[0137] In this embodiment, if the time from the first assembly of the smart meters in the equipment room at the first location to the most recent failure of the smart meters is 2 months, and during these two months, the number of faulty smart meters in the equipment room is 1, then the failure period of the smart meters in the equipment room at the first location is 2 months.

[0138] According to the data collected by the information collection module, the failure periods of the smart meters in the equipment rooms from the second location to the sixth location are calculated to be 3 months, 4 months, 4 months, 6 months, and 24 months respectively;

[0139] By calculating the failure cycles of the smart meters in each smart meter module, the maintenance cycle is calculated. Under normal circumstances, every time a maintenance cycle is reached, it is judged whether to dispatch maintenance personnel for maintenance based on the total number of faulty smart meters and the average maintenance cost. The existence of the maintenance cycle, on the one hand, plans the time for maintaining smart meters, making the maintenance more planned and improving the maintenance efficiency. On the other hand, when the maintenance personnel maintain smart meters each time, under the condition that the equipment is working normally, the proportion of faulty smart meters among all smart meters is the largest. Under the condition of coordinating the maintenance cost, different numbers of meters equipped to each enterprise can be used as much as possible, and the sum of the travel cost and the cost of maintaining smart meters is the lowest, and the maintenance cost is the lowest.

[0140] The method of maintaining smart meters using the maintenance strategy includes:

[0141] Calculate the failure cycles of the smart meters in each smart meter module: They are respectively recorded as the first time period, the second time period... the Nth time period, and the symbol is represented as T 1 、T 2 ......T n

[0142] Calculate the least common multiple of all failure cycles as the maintenance cycle, denoted as D.

[0143] In this embodiment, the least common multiple of all failure cycles is calculated to be 24 months.

[0144] Calculate the number of smart meters configured in the smart meter module,

[0145] Set the quantity coefficient as K, which is related to the maintenance cycle and the maximum failure cycle of the electric meters, so as to ensure that each smart meter module contains at least 2 smart meters.

[0146] When the maintenance cycle D is equal to the maximum failure cycle, then, the quantity coefficient K≥2;

[0147] When the maintenance cycle D is greater than the maximum failure cycle, then, the quantity coefficient K≥1;

[0148] For the quantity coefficient K, in the actual application process, if the least common multiple of all failure cycles is equal to the maximum failure cycle of the smart meters in the equipment room, in order to ensure that there are at least two smart meters in the smart meter module with the least common multiple of the failure cycle, then, at this time, the maintenance coefficient K≥2.

[0149] Then,

[0150] Calculate the smart meter modules corresponding to the failure cycles as the first time period, the second time period... the Nth time period respectively;

[0151] Then, the number of smart meters to be set for each smart meter module is set in sequence as K*D / T 1 , K*D / T 2 ……K*D / T n .

[0152] In this embodiment, when the maintenance cycle D is equal to the maximum failure cycle, then the quantity coefficient K = 2. The number of smart meters to be set for each smart meter module is set in sequence as 2*(24 / 2) = 24, 2*(24 / 3) = 16, 2*(24 / 4) = 12, 2(24 / 4) = 12, 2(24 / 6) = 8, 2(24 / 24) = 2.

[0153] Calculate the number of smart meters in the smart meter module based on the maintenance cycle and the failure cycle of the smart meters in the smart meter module. At the same time, the quantity coefficient K is increased to ensure that in general, within one maintenance cycle, it will not happen that all the smart meters in the smart meter module fail and it is necessary to immediately dispatch maintenance personnel to repair the smart meters, reducing the maintenance cost and ensuring power consumption safety.

[0154] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0155] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
