Description
Technical Field
The invention belongs to the technical field of information processing, and particularly relates to a method for fusing and applying KKS codes and grid codes.
Background
Mesh coding can generally divide meshes into two broad categories, geographic meshes and management meshes. And forming different grid codes according to different division methods and coding rules.
A geographic grid is a spatial reference system that subdivides a geospatial area into cells of different dimensions. Commonly used geographic grids are primarily comprised of four main types: latitude and longitude spherical discrete geographic grids, self-adaptive spherical discrete geographic grids, discrete geographic grids based on map projection, and regular polyhedron spherical discrete geographic grids.
The management grids are various, the most common are urban comprehensive management grids, environment monitoring grids, traffic control grids and the like, and the regional division is generally performed on local geographic spaces aiming at different management fields.
The existing scheme implementation flow is as follows:
the KKS code is specifically composed of a process identifier, an installation place identifier and a position identifier. But in practice often only the process identification code is used alone.
Process identification
The system is used for identifying names of various process systems, names of equipment, serial numbers of the equipment, parts of the equipment and which unit the system belongs to.
For example: 10SGC01 AP001 KP01
The symbol before the identifier is a prefix symbol, which means that the identifier in the string is a process identifier and can be omitted in general; 10 denotes a 1# unit; SGC denotes fire water spray system; 01 denotes a particular water spray system (e.g., a service-changing fire protection system or other water spray system); AP001 denotes a # 1 water pump unit (including a motor); KP01 denotes the water pump components in the pump unit.
It should be noted that: the process identification is the most common in KKS coding, and is mainly used in the process specialties of steam turbines, boilers, electric bodies, coal conveying, chemistry, heating ventilation, water supply and drainage fire fighting, hydraulic engineering and the like.
② installation place Identification (Identification of installation points)
The device is used for marking the installation positions of electrical parts, instruments and control devices installed on an electrical switch cabinet, a dial plate and a control console.
For example: +10 CAA 03. A5.
"+" is a prefix symbol indicating that this identification is not a process identification; 10 denotes a 1# unit; CAA denotes a protection chain equipment cabinet; 03 denotes the number of the protection chain equipment cabinet; "·" is an installation site identification (unique); a is a label of vertical layering; and 5 is a horizontal position mark.
The installation site mark is mainly used in the professions of an electrical secondary line, an instrument control system and the like.
Position Identification (Identification of Location)
This is an identification for a macro building or area, representing space on a certain floor in a certain building.
For example: +10UHA 08R001
"+" indicates that this identification is not a process identification; 10 denotes a 1# unit; UHA indicates that the building is UHA plant (in KKS coding, all codes with U word heads represent the building uniformly); 08 denotes an eighth layer; r001 represents room No. 1.
The position mark is mainly used for indicating the position of equipment by a technical professional or indicating the position of a fire-fighting area and a designated terrain (surface area network) by a fire-fighting professional of a building structure.
In a word, each production device obtains a unique and special KKS code from the beginning of design, and the KKS code is adopted from purchasing, monitoring, inventory, installation, debugging, overhauling and retirement in the device management process. According to the KKS coding rule, the coding of parts on the device can be refined, wherein the parts comprise one screw on the device (if needed). Through KKS coding, the production equipment of a whole factory can be standardized, and the unified management of the equipment is completed. Meanwhile, all relevant data of the equipment can be displayed in a correlated manner through equipment coding, such as maintenance histories, nameplate parameter setting, document data and the like.
However, the existing scheme has the following defects:
the KKS code coding system is quite complete, but the requirement of various application scenes cannot be completely covered in practice, and the resource value of data is not sufficiently explored.
Especially, after a KKS code system is built at one time in a newly built power plant, the KKS code is often forgotten to be added by newly adding scattered equipment facilities in the daily operation process. Therefore, the data of the KKS code is incomplete, and the data value of the KKS code which is built at a large cost needs to be further explored.
One specific practical case is that in the statistics of work tickets of a certain power plant in 6 months of 2021, 131 work tickets without KKS codes account for 17.2 percent of the total (763) work tickets. The method mainly comprises the following types: (1) the accessory lacks the KKS code. Such as a first boiler slag bin, a No. 2 furnace 26 coal mill No. 1 coal powder sampling device, a coal conveying C7 driving room and the like; (2) the supporting facilities lack KKS codes. Such as a second machine inter-cooling tower rolling door, coal conveying C4 trestle lighting, a steel plate bin cable bridge and the like; (3) the area-type (non-dotted) facilities lack KKS codes. Such as a urea workshop underground pipe gallery, a steam turbine room gate area, a first coal conveying dry coal shed and the like.
The position indication in the KKS code does not have a spatially resolvable meaning.
The KKS code does not directly encode space, but also has position identification code, but does not directly include absolute space information that can be resolved by a computer, but only the identification of the building, room, and the like where the device is located. And the buildings are mainly classified according to functional purposes, and the attribute of the spatial position is not considered.
In addition, a large number of working scenes are generated inside a building, the position identification precision of the KKS code is not improved, for example, the position identification can only be identified to the level of a 2 nd layer 1 st room of a water turbine machine room, and the position relation among equipment of each facility in the same room cannot be expressed finely.
And 3. the KKS coding application is not convenient enough to support actual operation processes such as work tickets and the like.
The KKS code is displayed in a nameplate mode on the site of equipment, and needs to be manually interpreted and reported by a port. The existing device repair initiating process is as follows: when the field staff of the equipment finds a problem, the background order dispatching staff is connected by a telephone, the KKS code and fault information of the equipment are orally reported, and the background makes a maintenance work order (work order) according to the information. Apart from the situation of lacking KKS codes, the problems that often arise are: (1) the information reporting efficiency is low, the error is easy to occur when the front port head reports information, and the information needs to be reported repeatedly; slow background recording, irregular recording information and the like. (2) The problems found on the site are not recorded and stored effectively in data forms such as photos, and the transmission of information from the previous repair personnel to the subsequent maintenance personnel is not facilitated by simply describing the work ticket according to characters.
Therefore, according to the defects in the above scheme, the present application provides a method for fusing and applying the KKS code and the trellis code, which can effectively solve the above problems.
Disclosure of Invention
The invention aims to provide a method for fusing and applying KKS codes and grid codes, which realizes the data fusion of three dimensions of objects, space and management by using a related index technology of the KKS codes, the management grid codes and the space grid codes and solves the problems that the existing KKS code system cannot cover various scene requirements, has no space resolvable meaning in position representation and cannot support position-based big data analysis.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the invention relates to a method for fusing and applying KKS codes and grid codes, which comprises the following steps:
step S1: carrying out spatial grid division and coding on the factory area;
step S2: carrying out management grid division and coding on the factory area;
step S3: establishing a mapping of KKS code-space grid coding-management grid coding;
step S4: establishing reverse mapping of 'grid positioning point-management grid coding-KKS code in grid';
step S5: processing flow when the device does not have KKS codes;
step S6: based on the application of the KKS code and the mesh coding fusion.
As a preferred technical solution, in the step S1, the specific steps of performing spatial grid division and coding on the factory floor are as follows:
step S11: selecting a coordinate control point determined by a factory building design drawing as an origin to establish a rectangular coordinate system; wherein, the x axis is in the east-west direction, the y axis is in the north-south direction, and the z axis is vertical height;
step S12: carrying out equidistant grid division and step-by-step aggregation by taking meters as a basic unit;
step S13: and carrying out self-defined coding on the multi-scale grid.
As a preferred technical solution, in the step S12, the meter-level grid is a minimum unit; the grids can be aggregated from four quadrants of the origin, and every four planar grids are aggregated into a planar grid at the upper stage; the same principle is applied to three-dimensional grid aggregation.
As a preferred technical solution, the specific steps of performing management grid division and coding on the factory floor in step S2 are as follows:
step S21: and dividing management grids in the factory building and coding the management grids on the basis of the principle that the space is not overlapped and is not missed.
Step S22: in the factory building, a grid positioning point is set for each management grid.
Step S23: and dividing a management grid for the area outside the factory building and coding.
As a preferable technical solution, in the step S21, in the factory building, firstly, the management grid is divided according to the position of the building structure, so as to make the identification obvious and the space regular; secondly, large-scale equipment is prevented from being manually broken. According to practical conditions, the management grid is controlled to be about 100 square meters to 200 square meters as much as possible; the management grid division is mainly performed according to electronic drawings such as CAD and the like and referring to field observation information. The code of the management grid is set in the background of the database, such as the management grid 001, the management grid 002, etc., which are sequence codes.
As a preferred technical solution, in the step S22, the positioning point should have a marking property, so as to be convenient for taking a picture and scanning a code, and a certain point of a column, a wall or a device in the management grid can be selected; the distance between the positioning points is as uniform as possible; each positioning point obtains a code according to the 1 m grid where the positioning point is located, and the code is pasted on an accurate point position in a two-dimensional code mode; thus, each anchor point code maps a management mesh region.
As a preferred technical solution, in the step S23, the size of the out-of-building management grid may be larger, such as 200 square meters to 500 square meters. But the grid positioning points can not be set outside the factory building, and the positioning of each point can be directly determined by using the Beidou satellite navigation positioning terminal, the UWB positioning terminal and other devices.
As a preferred technical solution, in step S3, the mapping flowchart of "KKS code-spatial trellis encoding-management trellis encoding" is as follows:
step S31: acquiring the detailed specification and size of the equipment and the coordinates of the space position of the equipment;
step S32: combining the plant area space grid division and the coded data, and calculating to obtain a coded set of 1 meter of grids occupied by the equipment;
step S33: establishing an accurate mapping from the KKS code to the spatial trellis code;
step S34, spatial trellis code is associated with the management trellis code.
As a preferred technical solution, in step S4, the grid codes of the grid anchor points in the background database actually identify the management grid area where the grid anchor points are located, and the management grid area can be associated with all the device KKS codes in the grid; when a front-line employee utilizes a terminal such as a smart phone and the like, two-dimensional code information of a positioning point at the position is obtained through a code scanning function, a management grid area where the positioning point is located can be obtained through analysis in a background, and then all devices KKS codes which are registered and associated in the management area can be called and displayed, the front-line employee can check the devices which need to be reported and repaired in a list, upload a field photo and click to realize one-key reporting; therefore, the defect that the oral information is easy to make mistakes can be avoided, and the 'trace' of the process operation can be realized.
As a preferred technical solution, in step S5, when the employee finds that the device does not have the KKS code during repair on site, the relevant photo and text description need to be uploaded on site, the background operator generates the KKS code according to the established rule and incorporates the KKS code into the database, and the subsequent next process is normally executed.
As a preferred technical solution, in step S6, the KKS code data and the field code scanning of the smart terminal may form a plurality of applications, and the steps are as follows:
step S61: the spatial location of the device "falls on the map";
step S62: process management for human operation;
step S63: indoor positioning and one-key alarming are carried out in the code scanning room;
step S64: location-based big data analysis.
As a preferable technical solution, in step S61, the original KKS code data is only in the form of a database table, and does not have a spatial distribution visualization function. Based on the newly added grid codes, the space position 'map falling' of the equipment can be realized, and visual checking and further statistical analysis of spatial distribution such as routing inspection data and maintenance data are facilitated.
As a preferred technical solution, in step S62, the KKS code and the grid coded data are combined with data such as the intelligent terminal photographing, code scanning data, and field monitoring video, so as to implement the current real-time process management of the operation behaviors of the personnel such as the equipment inspection, the maintenance task, the two ticket operation, and the like, and also perform task assistance according to a preset plan of time and space dimensions.
As a preferred technical solution, in step S63, the two-dimensional code is scanned on site to obtain accurate information of the location, and the method has a certain indoor positioning function, and further can realize indoor navigation by combining with a background map function; under the critical condition, one-key alarm help seeking with accurate position can be realized by scanning codes. The method is a realistic alternative scheme with high cost of the indoor high-precision positioning equipment at present.
As a preferable technical solution, in step S64, on the basis of the data such as the locations of the devices and the personnel, analysis such as spatial distribution and temporal distribution of the device failures may be performed, and further, the correlation between the device failures and the inspection tasks and the association between the device failures and the operators may be analyzed, and risk dynamics and security situations of the grid area may be managed.
The invention has the following beneficial effects:
(1) the invention introduces the idea of gridding management into factory and equipment management, realizes the data fusion of three dimensions of object, space and management by establishing the associated index of KKS code, management grid coding and space grid coding, and particularly realizes the event spatialization and management process of equipment management and operation.
(2) On the premise that indoor high-precision positioning is not popularized yet, the performance-price ratio of a mode of pasting the two-dimensional code on site is high, and fine trace retention in the working process can be realized by using coding of grid positioning points (1 m space grids);
(3) according to the invention, new social means of information such as on-site code scanning and photographing of the intelligent terminal are embedded into the original working process, so that dynamic space-time fine 'mark retaining' in the working process is realized, the process noise interference of manual reporting is reduced, and the existing data resources such as KKS codes are favorably activated and utilized.
Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention is a method for fusing a KKS code and a trellis code, including the following steps:
step S1: carrying out space grid division and coding on a factory area;
step S2: carrying out management grid division and coding on the factory area;
step S3: establishing a mapping of KKS code-space grid coding-management grid coding;
step S4: establishing reverse mapping of 'grid positioning point-management grid coding-KKS code in grid';
step S5: processing flow when the device does not have KKS codes;
step S6: based on the application of the KKS code and the mesh coding fusion.
As a preferred technical solution, in step S1, the specific steps of performing spatial grid division and coding on the factory floor are as follows:
step S11: selecting a coordinate control point determined by a factory building design drawing as an origin to establish a rectangular coordinate system; wherein, the x-axis is in the east-west direction (the east direction is positive), the y-axis is in the north-south direction (the south direction is positive), and the z-axis is vertical height (the sky direction is positive);
step S12: carrying out equidistant grid division and step-by-step aggregation by taking meters as a basic unit;
step S13: self-defining coding is carried out on the multi-scale grids, and the query calculation efficiency is improved through a coding form;
for example: code 00010002300
Bit 1, 0, represents the northeast quadrant (quadrant 1) at the origin, bits 2 through 6, 00100, represents the forward 100 th 1 meter grid in the x-direction, and bits 7 through 11, 02300, represents the forward 2300 grid in the y-direction.
In step S12, the meter-level grid is a minimum unit; the grids can be aggregated from four quadrants of the origin, and every four planar grids are aggregated into a planar grid at the upper stage; the same principle is applied to three-dimensional grid aggregation.
In step S2, the specific steps of performing management grid division and encoding on the factory floor are as follows:
step S21: and (4) dividing management grids in the plant on the principle of no space overlapping and missing and coding.
Step S22: in the factory building, a grid positioning point is set for each management grid.
Step S23: and dividing a management grid for the area outside the factory building and coding.
In step S21, in a factory building, dividing a management grid according to the positions of building structures (walls, columns, etc.) is considered, so as to make the identification obvious and the space regular; secondly, large equipment (such as a steam turbine) is prevented from being manually broken. According to practical conditions, the management grid is controlled to be about 100 square meters to 200 square meters in unit dimension as much as possible. The management grid division is mainly performed according to electronic drawings such as CAD (computer aided design) and the like, and is performed by referring to field observation information. The code of the management grid is set in the background of the database, such as the management grid 001, the management grid 002, etc., which are sequence codes.
In step S22, the anchor point should have a landmark property to facilitate photographing and code scanning, and a certain point of a column, a wall or a device in the management grid can be selected. The distance between the positioning points is as uniform as possible. Each positioning point obtains a code according to the 1 m grid where the positioning point is located, and the code is pasted on an accurate point position in a two-dimensional code mode. Thus, each anchor point code maps a management mesh region.
In step S23, the size of the out-of-plant management grid may be larger, such as 200 square meters to 500 square meters. But the grid positioning points can not be set outside the factory building, and the positioning of each point can be directly determined by using the Beidou satellite navigation positioning terminal, the UWB positioning terminal and other devices.
In step S3, the mapping flowchart of "KKS code-spatial trellis encoding-management trellis encoding" is as follows:
step S31: acquiring the detailed specification and size of the equipment and the coordinates of the space position of the equipment;
step S32: combining plant area space grid division and coded data, and calculating to obtain a coded set of 1 meter grids occupied by the equipment;
step S33: establishing an accurate mapping from the KKS code to the spatial trellis code;
step S34, spatial trellis code is associated with the management trellis code.
The mapping of the KKS code, the spatial grid code and the management grid code is an accurate mapping mode, and when an accurate coordinate of the position of the device is not sought, a simple mapping mode can be adopted, and the specific implementation is as follows:
because the accurate coordinate workload of the position where the actual acquisition equipment is located is too large, and the KKS level structure shows that the low-level KKS belongs to the high-level KKS codes, the 'process system' level KKS codes with relatively limited quantity can be hung on the management grid in a field marking mode and the like, and the 'equipment and part' level KKS codes with numerous quantity are indirectly hung on the management grid in an upward attribution mode;
for example: for the KKS code "═ 10SGC01 AP001 KP 01", only the management grid code corresponding to SGC01 (fire water spray system 1#) needs to be determined, and subordinate component devices such as AP001 KP01 and the like are directly hung to SGC 01. The management grid corresponding to the SGC01 system is specifically determined according to the outer contour of the system. (ignoring the mapping of the device to the exact spatial grid).
For linear facilities (systems) such as fire-fighting water pipelines and the like, a plurality of management grids are often spanned, the systems are required to be associated with each management grid code, and the management grids to which main equipment and parts belong respectively according to space need to be marked artificially.
In step S4, the grid code of the grid anchor point in the background database actually identifies the management grid area where the grid anchor point is located, and the management grid area can be associated with all the device KKS codes in the grid; when a front-line employee utilizes terminals such as a smart phone and the like, two-dimensional code information of a positioning point at the position is obtained through a code scanning function, a background can obtain a management grid area where the positioning point is located through analysis, and further all devices KKS codes registered and associated in the management area can be called and displayed, the front-line employee can check devices needing to be reported and repaired in a list, upload a field photo and click to realize one-key reporting. Therefore, the defect that the oral information is easy to make mistakes can be avoided, and the 'trace' of the process operation can be realized.
In step S5, when the employee finds that the device does not have the KKS code during repair on site, the relevant photos and text descriptions need to be uploaded on site, the KKS code is generated by the background operator according to the established rules and is included in the database, and the subsequent next process is normally executed.
In the step S6, KKS code data can be combined with intelligent terminal field code scanning to form various applications, and the steps are as follows:
step S61: the spatial location of the device "falls on the map";
step S62: process management for human operation;
step S63: indoor positioning and one-key alarming are carried out in the code scanning room;
step S64: location-based big data analysis.
In step S61, the original KKS code data is in the form of a database table only, and does not have a spatial distribution visualization function. Based on the newly added grid codes, the space position 'map falling' of the equipment can be realized, and visual checking and further statistical analysis of spatial distribution such as routing inspection data and maintenance data are facilitated.
In step S62, the KKS code and the grid coded data are combined with data such as the intelligent terminal photographing, code scanning data and the field monitoring video, so that the current real-time process management of the operation behaviors of the personnel such as the equipment inspection, the maintenance task, the two-ticket operation and the like is realized, and the task assistance can be performed according to the preset plan of time and space dimensions.
In step S63, the two-dimensional code is scanned on site to obtain the accurate information of the position, so that the system has a certain indoor positioning function, and further can realize indoor navigation by combining with the background map function; under the critical condition, one-key alarm help seeking with accurate position can be realized by scanning codes. The method is a realistic alternative scheme with high cost of the indoor high-precision positioning equipment at present.
In step S64, on the basis of aggregating data such as the locations of devices and personnel, analysis such as spatial distribution and temporal distribution of device faults may be performed, and further analysis of the correlation between device faults, the correlation between device faults and inspection tasks, and the correlation between device faults and operators may be performed, and risk dynamics and security situations of the grid area may be managed.
Embodiment one (management network division and coding for factory floor)
In the factory building, a grid positioning point is set for each management grid. Each positioning point obtains a code according to the 1 m grid where the positioning point is positioned, and the code is pasted on the ground or the position close to the wall in a two-dimensional code mode. Each anchor point code maps a management grid area. E.g., a site trellis code 00010002300, into a two-dimensional code as shown in fig. 2.
The grid cells can be defined and managed outside the factory as required and coded in the background of the database. But the grid positioning points can not be set outside the factory building, and the positioning of each point can be directly determined by using the Beidou satellite navigation positioning terminal, the UWB positioning terminal and other devices.
Embodiment two (establishing the reverse mapping of ' grid positioning point (1 m space grid coding) ' -management grid coding-KKS code in grid ')
When a front-line employee utilizes terminals such as a smart phone and the like, a positioning point two-dimensional code of the position where the positioning point is located is obtained through a code scanning function, a background can obtain a management grid area where the positioning point is located through analysis, and then all registered and associated device KKS codes in the management area can be called and displayed. Therefore, the defect that the oral information is easy to make mistakes can be avoided, and the 'trace' of the process operation can be realized.
Example (c):
as shown in fig. 3, the two-dimensional code (whose value is: grid code 00010002300) attached to the site is scanned to obtain a mapped management grid 003, which is then automatically associated with all device codes (4 devices) in the management grid area. And checking required equipment and uploading information such as fault pictures and the like for repair.
