Description
Technical Field
The invention discloses a thermal image recording device and a thermal image recording method, and relates to the application fields of thermal image recording devices, thermal image processing devices and thermal image recording.
Background
Infrared thermography is different from visible light images, and in the captured visible light images, the captured objects can be confirmed through information in the images, such as colors, nameplates, shapes and the like, so as to identify the objects; the infrared thermography is not easy to confirm the shot specific shot object through the information in the image, and if the shot specific shot object cannot be effectively identified through colors, nameplates and the like, a user is very easy to miss shooting when shooting.
Moreover, since infrared detection shooting often requires shooting a large number of similar subjects, the similar subjects may be the same or different types. For example, a plurality of groups of shot objects with different equipment areas exist in a transformer substation, and the plurality of groups of shot objects may be adjacent to each other, and even if three different shot objects with the same shape of A, B, C with different numbers exist in the same group of shot objects, since the different shot objects with the same type are almost the same in an infrared image, shooting is easy to be omitted, shooting is confused and disordered, and efficiency is reduced; this situation is exacerbated when multi-angle shooting is required, or when multiple parts (e.g., specific parts, specific locations) of the same subject are shot.
At present, thermal image files obtained by a thermal image shooting device are generated into file names according to time or sequence numbers; the method comprises the following steps of storing and analyzing for subsequent arrangement, distinguishing thermal image files corresponding to a shot object, and recording shot object information correspondingly by a user according to a field nameplate recognized or recognized by the shot object during infrared detection, wherein the file name of the thermal image file and the corresponding shot object information are recorded by conventional common recording modes such as manual paper, and voice annotation of the shot object information on the field is added to the thermal image file; the above methods have various inconveniences such as inconvenient operation, easy error, influence on the shooting speed, large subsequent arrangement workload and the like. The user holds the portable thermal image shooting device in the prior art, the workload is very large, and usually in infrared detection, one person is needed to shoot and the other person needs to record paper.
Subsequent processing, such as batch processing and analysis of a large number of thermal image files, needs to obtain the object information corresponding to the object thermal images of the thermal image files, so that the automatic batch processing of the object thermal images can be completed by the computer; the existing manual recording also needs workload of associating the shot object information such as manual naming of the thermal image file and the like according to the shot object information recorded manually, and the workload of subsequent arrangement is huge and is easy to make mistakes.
Moreover, due to the reasons mentioned above, the user is inconvenient to correspond to the shot object information by identifying the information in the infrared thermal image, so that the inconvenience of manual recording of the shot object information and subsequent manual naming and sorting work during shooting is aggravated.
Since the application of the thermal image detection technology, no proper means is available for conveniently and quickly correlating the recorded thermal image file with the shot object information. The technical personnel in the field always try to solve the problems, such as a thermal image shooting device additionally provided with a GPS device, can prompt GPS prompt information in the shooting of a power line, and can record the GPS information and a thermal image file in a correlation manner; however, the user is not easy to correspondingly understand the specific object to be shot through the GPS information; and when there are a plurality of objects densely located at the same place and respective shooting records are required, the associated record GPS information cannot be specifically associated with a specific object. The prior art also does not solve the problem that shooting is easy to miss, and how to conveniently record the association between the thermal image file and the corresponding shot object information is a problem.
Accordingly, it is appreciated that there is a need for an infrared recording device that addresses the problems that exist today.

For example, the operation unit 11 is configured by a recording key 01 (configured to perform a recording instruction operation), a switching key 02 (configured to perform a switching instruction operation of subject information), a focus key 03, an enter key 04, a cross key 05, and the like shown in fig. 2, and the recording key 01, the switching key 02, and the like may be configured to perform a predetermined instruction operation, and the control unit 10 may continuously perform recording and switching processing in response to a signal of the operation. Without being limited thereto, the operation may be realized by using the touch panel 06, a voice recognition part, or the like.
The control unit 10 controls the overall operation of the thermal image system 13, and the flash memory 9 stores a program for control and various data used for controlling each unit. The control program enables the control part 10 to execute the control of processing in various modes, after the power is switched on, the control part 10 initializes the internal circuit, then, the standby shooting mode is entered, namely, the shooting part 1 shoots to obtain the thermal image data, the image processing part 2 carries out the specified processing on the thermal image data shot by the shooting part 1 and stores the thermal image data in the temporary storage part 6, the control part 10 executes the control on the display control part 3, the infrared thermal image is continuously displayed on the display part 4 in a dynamic image form, in the state, the control part 10 implements the control and continuously monitors whether the processing is switched to other modes or the shutdown operation is carried out according to the preset conditions, and if the processing is carried out, the corresponding processing control is entered. The control unit 10 is realized by, for example, a CPU, an MPU, an SOC, a programmable FPGA, or the like.
The information mode will be explained below, and in the present embodiment, the control section 10 functions as an example of an information specifying section, a display control section, a progress statistic section, and the like. In this embodiment, a scene in which a user performs infrared detection on a subject whose device types are device i, device ii, and device iii in a device area 1 (1001), a device area 2 (1002), and a device area 3 (1003) in a substation 1 shown in fig. 10 is taken as an example; before the main shooting, data files of the subject information to which the sort order is added are stored in advance in the flash memory 9 (or in a storage medium such as the memory card 8 or the temporary storage unit 6). The present embodiment is explained with reference to fig. 3 to 10. Referring to fig. 3, the control steps are as follows:
in step S101, the control unit 10 performs control to continuously detect whether the user selects the information mode through the operation unit 11.
If yes, go to step S102; the control section 10 transfers the subject information (partially or entirely) added with the sort order stored in the flash memory 9 to the temporary storage section 6, and the transferred subject information may be all of the subject information or predetermined partial information, for example, predetermined partial information for obtaining subject instruction information. Further, after the power is turned on, the information may be transferred to the temporary storage unit 6.
In step S102, object information as special object information is specified.
An information specifying unit (control unit 10) for specifying subject information as special subject information based on the subject information added with the sorting order stored in the information storage unit; in a preferred embodiment, the first subject information "substation 1 device area 1 device ic phase" in the ranking order is designated as the special subject information based on the ranking order, and the process proceeds to step S103.
In another embodiment, the control unit 10 monitors whether or not there is an operation instruction to select the special object information; here, in a case where the operation instruction is confirmed, the subject information corresponding to the selected subject instruction information is designated as special subject information; a display control unit for controlling the display unit to display a predetermined number of pieces of subject instruction information based on the plurality of pieces of subject information added with the sort order stored in the information storage unit; an information specifying unit specifies subject information as special subject information based on a user's selection. For example, in the object instruction information shown in the object information display field 601 of fig. 6, the user can select one of the object instruction information through the operation section 11, and the control section 10 designates the object information corresponding to the object instruction information as the special object information. In addition, the user can also enter a display interface of new shot object indication information in a mode of page turning, scroll bar moving and the like to select the new shot object indication information as the shot object indication information; further, the subject information as the special subject information may be specified from the starting point of the previously default sorting order, for example, the subject information as the special subject information which was last specified when used last time, and the subject information next to the sorting order thereof as the currently specified starting point.
Step S103, transmitting the thermal image data obtained by shooting through the shooting part 1 to the temporary storage part 6; the image processing unit 2 performs predetermined processing such as pseudo-color processing on the thermal image data captured by the imaging unit 1 to obtain image data of an infrared thermal image, and stores the image data in the temporary storage unit 6.
And step S104, the control part 10 controls the display part 4 to display the infrared thermal image generated by the thermal image data, and simultaneously, the special shot object indication information obtained by the special shot object information specified by the information specification part is specially displayed.
The object indication information and the infrared thermal image are jointly displayed in the display interface, and the object indication information and the infrared thermal image can be superimposed in the infrared thermal image and/or not superimposed in the infrared thermal image.
The special display is, for example, as shown in fig. 7, as the object instruction information obtained by displaying only the specified special object information.
The special display is, as when the subject instruction information obtained by the prescribed number of subject information not limited to the special subject information is displayed, wherein the subject instruction information obtained from the specified special subject information is specially displayed in a display manner distinguished from other subject instruction information.
In a preferred embodiment, the display control unit controls the display unit 4 to display the infrared thermal image generated from the thermal image data, and displays the subject indication information obtained from the specified special subject information in a display manner different from that of the other subject indication information, based on the subject information added with the sorting order stored in the information storage unit (determined by the task determination unit when there is the task determination step), and displaying a predetermined number of pieces of subject information in the sorting order of the subject information.
As shown in a display interface 601 in fig. 6, the control unit 10 controls to display the subject instruction information obtained by a predetermined number of pieces of subject information in the order of the subject information, and the underlined mark of "substation 1 equipment area 1 device ic phase" may be distinguished from other subject instruction information, or a display position, color, background, size, font, character description, or the like which is easily recognized by the user may be used as a special display mode distinguished from other subject instruction information.
In another preferred embodiment, the display control unit displays predetermined information for generating the subject instruction information among the subject information in a hierarchical manner, that is, in a predetermined hierarchy and attribute information corresponding to each hierarchy. The layered display is, for example, a tree-like display, as shown in the object information column 801 shown in fig. 8, the control unit 10 divides the object indication information into three layers according to the attribute information of the transformer substation, the equipment area, the equipment type and the other specified attributes, and displays the three layers according to the specified positions, and also superimposes the object indication information 802 that is specifically displayed in the infrared thermal image, which is convenient for the user to observe.
Specifically, in one display control implementation, the image processing unit 2 is controlled to synthesize image data of an infrared thermal image generated by thermal image data obtained by shooting and image data of subject indication information obtained by specified special subject information; storing the synthesized image data in a temporary storage unit 6; then, the display control unit 3 is controlled to display the synthesized image data on the display unit 4. As shown in fig. 7, wherein the synthesis superimposes the object indication information in the infrared thermal image at a prescribed transparency ratio. When there is other predetermined indication information, the image processing unit 2 is controlled to combine the image data of the infrared thermal image generated by capturing the obtained thermal image data, the image data of the specially displayed object indication information obtained by the specified specially object information (when there is a specially displayed mark, the image data including the mark as underlined in fig. 6), and the image data of the other predetermined indication information; and controls the display control section 3 to display the synthesized image data on the display section 4, as shown in fig. 6, the synthesis combines the subject indication information and the infrared thermography, and displays the combined image data in different regions without overlapping each other or a small amount of overlapping. Other instruction information includes a predetermined number of pieces of subject information and schedule information, and instruction information such as date and battery capacity displayed on the display unit.
The object indication information obtained from the object information may be obtained as all or a predetermined part of the object information, and the information configuration for obtaining the object indication information in the object information may be predetermined.
Wherein the control section 10 functions as a progress counting section for counting the shooting progress information on the basis of the number of the subject information to which the sorting order is added (determined based on the task determining section when there is the task determining step) stored in the information storage section and the currently specified special subject information; the control section 10 controls the display of progress information, such as progress information 603 displayed in 601 in fig. 6 and progress information 604 displayed in 602; note that, in fig. 6, in the case where the order indication information (number) of the specifically designated subject information has already been displayed, the number may also constitute progress information with the total number "15" of the displayed subject information.
Note that the sort order corresponding to the subject information may be displayed or not, and in fig. 6, order instruction information (serial number) obtained from the sort order information corresponding to the subject information to which the sort order is added stored in the information storage unit (when the task determination unit determines that there is a task determination step), is displayed.
Step S105, the control unit 10 determines whether or not a recording instruction operation is performed, and if not, jumps to step S107; when the user performs photographing on the corresponding subject by recognizing the corresponding subject or viewing the device signboard according to the subject instruction information "substation 1 device zone 1 device ic phase" in the display interface 601, and when the record key 01 of the operation unit 10 is pressed, the control unit 10 responds to the record instruction operation, the process proceeds to step S106.
In addition, the control unit 10 may be configured to perform the recording operation based on other predetermined recording conditions; for example, when it is determined that a predetermined time interval is met, for example, the temperature value in the thermal image exceeds a predetermined threshold, for example, when a predetermined recording condition such as a trigger signal of another sensor device connected to the thermal image device 13 is detected, the process automatically proceeds to step S106 to execute the recording process even if the recording instruction operation of the operating unit 11 is not performed. The predetermined recording condition may be a condition in which, even if the recording instruction operation by the operation unit 11 is performed, the recording process is performed when other predetermined conditions are simultaneously satisfied, for example, a predetermined time interval is satisfied, or a temperature value in the thermal image exceeds a predetermined threshold value. Obviously, the prescribed recording condition may be various conditions configured in advance.
Step S106, a recording process.
The control unit 10 as a recording unit associates and records predetermined infrared data with information on the designated special subject information in response to a recording instruction operation or in accordance with predetermined recording conditions. And then proceeds to step S107.
The infrared data are thermal image data obtained by shooting through the shooting part and/or data obtained by performing specified processing on the thermal image data obtained by shooting through the shooting part.
Prescribed infrared data, for example, thermal image data (frames) obtained by reading signals by an infrared detector in response to (or following) a prescribed time at which a recording instruction operation is performed or a prescribed recording condition is judged to be satisfied; for example; specified thermal image data (frames) among the thermal image data of the plurality of frames temporarily stored in the temporary storage 6 in response to a recording instruction operation or at a time (or a specified time thereafter) at which it is judged that the specified recording condition is satisfied; for example, the thermal image data in the above case is data obtained by performing predetermined processing (one or more of predetermined processing such as correction, interpolation, pseudo color, conversion to a temperature value, pixel reduction, compression, and the like); for example, recording a specified number of frames of thermal image data; for example, a predetermined number of frames of thermal image data are subjected to predetermined processing to obtain thermal image data (frames), for example, the integration operation is performed on the plurality of frames of thermal image data stored in the temporary storage unit 6 to obtain a processed frame of thermal image data; for example, one or more of the infrared data obtained in these cases may be used, such as simultaneously recording the temperature value of each pixel obtained from the thermal image data and the image data of the infrared thermal image.
Specifically, in one embodiment, in response to the recording instruction operation of the operating unit 11, the control unit 10 controls the infrared detector to read a signal to obtain thermal image data, and causes the image processing unit 2 to perform predetermined thermal image data compression processing on the thermal image data, or performs predetermined processing such as correction and interpolation on the thermal image data, and then performs compression processing, associates information related to the specified specific subject information in the temporary storage unit 6 with the compressed thermal image data, generates a thermal image file, records the thermal image file in the memory card 8, and ends the processing. Further, the compression may be performed after the information is added.
The information related to the specified special subject information may be, for example, all of the information of the subject information as the special subject information, or part of the information, for example, preferably, may record information representing the identity of the subject, such as "substation 1 device area 1 device ic phase"; however, in other examples, for example, "device area 1 device ic phase" may be recorded, and for example, the sort order information added to the subject information may be recorded; the subject information may include other information not used for generating the instruction information, for example, the subject information may include information such as other number and model number, and the information of the other number and model number may be stored, although not shown.
An embodiment of the associated record is to attach information related to the specified special object information as information of infrared data in a prescribed format, see an implementation diagram of a thermal image file structure in fig. 9; the infrared data 901 is thermal image data obtained by compressing thermal image data read from an infrared detector at the moment of responding to the recording indication operation; information 902 relating to the special subject information is subject information representing "substation 1 equipment area 1 equipment ic phase"; other additional information 903 such as time of shooting, parameters related to shooting such as ring temperature, distance, and the like.
Further, the association recording process may also record information related to the particular subject information in an information file or an index file or the like associated with the thermal image file, which the control section 10 may generate; furthermore, a thermographic file name may also be generated from the particular subject information, the recording section having a file name generating unit for generating a file name of the thermographic file, the file name containing at least information relating to the specified particular subject information; for example, the generated thermal image file name: the equipment zone 1 of the transformer substation 1 is provided with equipment I C phase and jpg phase; but attribute information is not classified and stored, so that subsequent batch processing is not convenient, and the computer is inconvenient to recognize mixed characters; preferably, the file name including the classification information is generated by performing information classification arrangement based on the classification information in the object information, and for example, the file name is generated based on predetermined attribute information: 1-equipment region 1-equipment I-C phase of transformer substation, jpg, wherein attribute information can be classified in a-equal separation mode; further, a file name is generated by combining the time information '20120223', such as 1 part of the transformer substation, 1 part of the equipment area, I-C phase of the equipment, 20120223. jpg; the essence of the association record is to record the information needed for subsequent batch analysis, the file name contains the shot object information to facilitate the user to check, and the file name containing the recognizable classification information is generated according to the classification information in the shot object information to facilitate the subsequent batch analysis to read and recognize the classification information in the file name.
It is obvious that it is preferable that the classification information in the file name should include information representing the identity of the object to be photographed, corresponding to the object to be photographed.
In step S107, the control unit determines whether or not there is a switching instruction operation of the operation unit 11, and if not, the control unit returns to step S103 to display the object instruction information together with the continuous dynamic infrared thermography (continuous synthesis), and if the control unit 10 detects the switching instruction operation from the operation unit 11, the control unit proceeds to step S108.
When the user finishes shooting the corresponding object according to the object indication information 'equipment ic phase 1 in equipment area 1 of substation 1' in the display interface 601, and then presses the switching key 02 of the operation part 10 and other keys representing switching, the operation of finishing the switching indication operation by one-key operation is realized, and here, the user does not need to look at the object information shown in the display interface 601 for selection or search, and the operation is simple.
Further, the control unit 10 may be configured to perform the switching operation based on a predetermined switching condition; for example, when it is determined that a predetermined time interval is met, for example, when the temperature value in the thermal image exceeds a predetermined threshold, for example, when a predetermined switching condition such as a trigger signal of a device connected to the thermal image device 13, for example, another sensor device or the like is received, even if the switching instruction operation of the operation unit 11 is not performed, the process automatically proceeds to step S108. The predetermined switching condition may be a condition in which, even if the switching instruction operation of the operation unit 11 is performed, a predetermined switching process is performed when other predetermined conditions are simultaneously satisfied, for example, a predetermined time interval is satisfied, or a temperature value in the thermal image exceeds a predetermined threshold value. Obviously, the prescribed switching condition may be various conditions configured in advance.
In step S108, the control unit 10 determines whether or not the task is completed.
In response to the switching instruction operation, the control section 10 judges whether or not the designation of the last subject information in the sorting order sequence is completed; if not, the process returns to step S102, and at this time, the designated special object information is switched in the order of the order based on the object information to which the order is added, which is stored in the information storage unit. If the operation is finished, the information mode is finished, characters such as 'task completion' and the like can be displayed on the screen, and then the thermal image device returns to the standby state to wait for the user to enter the operation of other modes. Alternatively, the imaging may be performed by switching to a predetermined starting point of the sort order, for example, the starting point of the sort order.
Specifically, in one embodiment, the information designating unit (control unit 10) adds 1 to the sequence number of the sorting order corresponding to the special subject information designated before the switching, and then determines whether the last one in the sequence of the sorting order is completed, and if the last one is not completed, searches for and designates the subject information corresponding to the sequence number of the sorting order obtained by adding 1 to the sequence number of the sorting order as the special subject information; and if the operation is finished, exiting. Further, it is not necessary to judge whether or not the designation of the last object information in the sequence of the sort order is completed, and it may not be judged that every time the switching instruction operation is received, that is, the object information corresponding to the sequence number of the sort order obtained by adding 1 to the sequence number of the sort order is designated as the special object information, and when not found, the 1 is added to continue the search until a prescribed timing is exceeded, or the information mode is not ended until the control section 10 receives the exit instruction.
Returning to step S102, the information specifying unit switches the specified special object information (i.e., switches the specified object information as the special object information) based on the sort order.
Wherein the specified special subject information is switched; in a preferred embodiment, the information specifying unit switches the single object information specified as the special object information from the single object information specified as the special object information before switching to the next object information in the sorting order sequence (the sorting order sequence of the object information determined for the task determining unit when there is the task determining step). For example, in this example, the single object information designated as the special object information is switched from the single object information "substation 1 equipment area 1 device ic phase" designated as the special object information before switching to the next object information "substation 1 equipment area 1 device ib phase" in the sorted order "designated as the special object information before switching.
The display control part controls the display part to display the infrared thermal image generated by the thermal image data, and simultaneously displays the shot object indication information obtained by switching the specified special shot object information by the information specifying part in a special display mode. As shown in the display interface 602, the subject instruction information "substation 1 equipment area 1 device ib phase" obtained by switching the specified special subject information "substation 1 equipment area 1 device ib phase" by the information specifying unit is displayed in a special display manner. The progress information 603 displayed in 601 is changed to the progress information 604 displayed in 602. Then, a user can shoot a corresponding shot object according to specially displayed shot object indication information of 'equipment I B phase of 1 equipment zone of the transformer substation 1'; obviously, when the recording instruction operation is performed again, the specified special subject information is switched by the information specifying unit, and the recording unit, in response to the recording instruction, associates and records the predetermined infrared data with the information on the special subject information "substation 1 equipment area 1 equipment ib phase" specified after the switching. This allows the user to easily perform imaging through the imaging path L10 shown in fig. 10, and thus the user is less likely to miss an object.
The information specifying unit switches the single object information specified as the special object information from the object information specified before switching as the special object information to the object information specified before switching as the last object information in the sorting order. The switching is performed based on the sort order, which may be the order of the sort order sequence or the reverse order, and it may be specified whether the switching is performed in the order of the sort order or the reverse order.
Further, when the information specifying section specifies the subject information as the special subject information as two or more pieces of subject information adjacent in order; the information designating unit sorts the specified specific number of pieces of adjacent subject information as the special subject information into the specific number of pieces of adjacent subject information starting from the specific number of pieces of adjacent subject information designated before switching.
For example, when "equipment zone 1 of substation 1, equipment zone 1, equipment ib of substation 1, and" equipment zone 1, equipment ia phase of substation 1 "are designated at the same time, in response to the switching instruction operation, the switching designation" equipment zone 1 of substation 1, equipment ia, equipment zone 1 of substation 1, equipment iib of substation 1, and equipment zone 1, equipment iic phase of substation 1 "are used as the special subject information.
Further, when the information specifying section specifies the subject information as the special subject information as two or more pieces of subject information adjacent in order; there may also be cases where switching is done in reverse order.
It should be noted that in this embodiment, the information of the object with a small number is exemplified, and in the actual infrared detection operation, the number of objects is large, and the effect of the embodiment of the present invention is significant.
Similarly, for complex equipment or the situation that multi-angle shooting is needed, relevant object information and the sequencing sequence thereof can be prestored and stored for objects (such as components, angles and the like) needing to be shot separately, and omission of shot parts can be avoided.
As described above, based on the plurality of pieces of subject information to which the sorting order is added, the subject indication information and the infrared thermal image obtained by specifying the special subject information and displaying the special subject information on the display unit 4 in particular, in the present embodiment, the subject information includes information representing the location (such as a substation, an equipment area), the type (such as a transformer, a switch, and the like, which is the type of electric equipment), the number (such as the phase, and the like) of the subject, and the like, and the subject indication information includes information representing the identity of the subject, which can facilitate the user to confirm the photographed subject. Through checking the cognition of the corresponding shot object or the equipment signboard, the user takes the specially displayed shot object indication information as the indication information of the currently shot object, checks the cognition of the shot object or the equipment signboard, confirms the shot object and reduces the condition of error shooting; when a recording instruction operation is performed, information on the infrared data and the specified special object information is recorded in association in response to the recording instruction operation, and when a switching instruction operation is performed, the specified special object information is switched in the sorted order, and object instruction information obtained by switching the specified special object information by the information specifying section is displayed in a special display manner. The purpose of prompting the user of the shot objects needing to be shot at present according to the sorting sequence is achieved, the condition of wrong paths or disorder is greatly reduced, and omission is avoided; thereby improving the shooting efficiency, reducing the working strength and being simple to operate. Wherein, through the display of the statistical shooting progress information, the user can reasonably arrange the shooting progress. In summary, example 1 is a preferred embodiment, although it is not necessary that all of the advantages described above be achieved simultaneously in any product that implements an embodiment of the invention.
Example 2
In the present embodiment, in the thermal image device 13 having the same structure as that shown in fig. 1, in the flash memory 9, a control program for a user to set filter conditions and a control program for determining subject information according to the filter conditions are stored; and a control program for continuously executing recording and switching of the specific object information in response to a prescribed instruction operation (e.g., one-key operation). The shooting task at this time is to shoot the object of which the object type in the substation 1 is the device i. The present embodiment is explained with reference to fig. 11 to 16.
In step S201, the control unit 10 performs control to continuously monitor whether the user selects the information mode through the operation unit 11, and when it is detected that the user selects the information mode, the process proceeds to step S202.
Step S202, setting filtering conditions;
in this embodiment, the control section 10 controls the display section to display a setting interface as shown in fig. 12; the display section 4, the operation section 11, and the control section 10 constitute an example of a task setting section.
And a task setting section for setting a filtering condition composed of a keyword and a filtering logical relationship related to the filtering condition.
The task setting part is provided with a keyword determining unit, a logic determining unit and a filtering condition generating unit, wherein the keyword determining unit is used for determining keywords related to filtering conditions; a logic determination unit for determining a filtering logic relationship of the keywords related to the filtering condition; and a filtering condition generating unit for generating a filtering condition according to the keywords related to the filtering condition and the specified filtering logic relation.
The keyword related to the filtering condition may be one keyword or a plurality of keywords; wherein the plurality of keywords includes representing a range of keywords such as a numeric range, an alphabetical range, a sort order range, a time range, and the like. In addition, when the subject information includes various information such as the attribution unit, classification level (for example, voltage level, importance level, etc.), model, manufacturer, performance, and characteristics, history of past shooting or inspection, date of manufacture, and lifetime, which are related to the subject, the keyword may be determined from the information to set the filtering condition.
A keyword determination unit for determining a keyword related to the filtering condition; for example, one or more of the following embodiments may be combined to determine keywords related to filtering conditions.
One embodiment, for example, pre-stored keywords, determines keywords associated with the filtering criteria based on user selection. As when the subject information as shown in fig. 5 is stored in the information storage portion, keywords for selection may be prestored, and the keyword selected by the user is determined as the keyword related to the filter condition.
One embodiment, for example, is a default keyword associated with the filter criteria.
One embodiment, for example, enters keywords by the user, and determines the keywords entered by the user as keywords related to the filter condition.
One embodiment, for example, provides a selection item of the selected keyword attribute, and determines the keyword corresponding to the keyword attribute as the keyword related to the filtering condition based on the keyword attribute selected by the user; this is the case where when some of the subject information has attribute information of a specific attribute, and other portions of the subject information do not have attribute information of the specific attribute, the subject information can be conveniently filtered.
In a preferred embodiment, a keyword for obtaining attribute information of a predetermined attribute in the subject information is searched based on the subject information stored in the information storage unit, and the keyword related to the filter condition is specified based on a selection of a user.
Specifically, the control unit 10 controls the display unit 4 to display a keyword menu item of a keyword query configured to represent attribute information of a prescribed attribute, such as the substation 1203, the device area 1204, and the device type 1205, on the filter condition setting interface illustrated in fig. 12. When the subject information shown in fig. 14 is stored in the information storage unit, the control unit 10 searches the subject information stored in the information storage unit based on the device type 1205 selected by the user in accordance with the current shooting "device i", obtains the keyword "device i, device ii, device iii …" of the attribute information of the predetermined attribute (device type), displays the list 1206, and the user selects "device i" from the list, and determines "device i" as the keyword related to the filter condition. Here, the display section 4, the operation section 11, and the control section 10 constitute an example of a task setting section; in this embodiment, when the types of keywords of the attribute information of the subject information are large, the operation becomes complicated.
In still another preferred embodiment, the keyword determination unit determines a keyword search condition, searches for a keyword that obtains attribute information of a predetermined attribute from the subject information that matches the keyword search condition based on the subject information stored in the information storage unit, and determines a keyword related to the filter condition based on a user selection; wherein the keyword query condition is one or more of the keywords related to the filtering condition determined before.
Specifically, when the object information as shown in fig. 14 is stored in the information storage portion, the object information of some other substation is also included unlike the case of fig. 4. The control unit 10 causes the display unit 4 to display a filter condition setting interface in the setting operation, as shown in the example of fig. 13, and when the user selects the substation 1303 via the operation unit 11, the control unit 10 inquires about keywords of attribute information of attributes of the substation based on the subject information stored in the information storage unit, and causes the list 1306 to be displayed; the user selects "substation 1" from among the plurality of keywords, and the control unit 10 determines "substation 1" as a keyword related to the filtering condition; then, when the device type 1305 is selected, the control section 10 determines "substation 1" selected by the user as a keyword query condition, and queries a keyword of attribute information that meets the device type attribute of the subject information of "substation 1", so that a list 1307 of "device i, device ii, and device iii" is displayed, and the user selects the device type "device i" from the list; the control unit 10 specifies "substation 1" and "equipment i" as keywords related to the filtering condition. Obviously, this way, the number of keywords to be selected will be simplified.
A logic determination unit, configured to determine a filtering logic relationship of the keyword related to the filtering condition; the filtering logical relationship may be that when the keyword related to the filtering condition is a keyword, the filtering of the keyword is a non-relationship; when the keywords related to the filtering condition are a plurality of keywords, the keywords are the combination of AND, OR, NOT logical relationship and filtering NOT relationship among the keywords; the filtering may be a default and the logical relationship between the non-relational and the keyword may be determined according to user settings.
An example of a keyword, for example, a keyword related to a filtering condition is a keyword "device i", see fig. 12, yes "1201 and no" 1202 options of a shooting condition for setting filtering non-relation; when yes is selected, the filtering condition generated by combining the keyword equipment I is used for subsequent searching and determining the shot object information conforming to the equipment I as a shooting task; when ' not ' is selected, the filter condition generated by combining the keyword ' equipment I ' is used for subsequent searching to determine the object information conforming to the ' equipment I ' which is not '. In this case, the logic determination unit determines the filtering non-relationship as "yes" according to the default filtering non-relationship as "yes". Then, when the user specifies the filtering condition through the operation unit 11, the filtering condition generating means (control unit 10) generates the filtering condition by combining the default filtering non-relation "yes" with the keyword "device i" selected by the user. At the time of task determination, object information conforming to the keyword "device i" will be searched as determined object information.
Examples of the plurality of keywords, such as keywords related to the filtering condition are "substation 1" and "device i", see fig. 13, the logic determination unit determines the filtering non-relationship as "yes" according to the default filtering non-relationship, and determines the logical relationship of the keywords "substation 1" and "device i" as "and" according to the default logical relationship (the keywords with different attributes are "and" relationship "); when the user specifies the filtering condition through the operation unit 11, the filtering condition generating means (control unit 10) combines the keywords "substation 1" and "equipment i" related to the filtering condition with the default logical relationship "and combines the default filtering non-relationship" yes "to generate the filtering condition. At the time of task determination, object information conforming to the keyword "substation 1" and conforming to "device i" is searched as determined object information.
The generated filter condition is recorded in the temporary storage unit 6 or in the flash memory 9 or the like (for example, a configuration file is generated) for later use.
In step S203, the task determination section determines subject information from the subject information stored in the information storage section, the determined subject information being used to specify the special subject information therefrom, which can be understood as the subject information included in the shooting task.
If "substation 1" and "equipment area 1" are used as the filter conditions, when the information storage unit stores the subject information as stored in fig. 14, the subject information that matches the keyword "substation 1" and that matches "equipment i" is searched as the determined subject information.
The determined subject information is shown in fig. 15, in which the number of shooting tasks for the other substations, "equipment area 2", and "equipment ii", "equipment iii", is reduced to "6" compared to before the task determination.
Obviously, the shooting path during the specific shooting task is simplified, the user looks at the equipment area information in the shot object indication information, the searching work of the equipment I in the equipment area 2 is avoided, the working strength is reduced,
further, step S202 is not essential, and the task determination section may determine subject information that meets the filter condition based on a pre-stored filter condition as a default; further, there are embodiments in which the task determination is performed, for example, when a plurality of data files (each including subject information to which a sort order is added) are stored in advance in the flash memory 9 (or the memory card 8), a user is provided to select a data file, and the subject information in the data file selected by the user is determined as the subject information included in the shooting task; further, the object information may be determined based on a user's selection of a plurality of object information.
Step S204 of specifying special subject information; an information specifying unit that specifies subject information as special subject information from the plurality of subject information specified by the task specifying unit.
The control unit 10 controls to designate, as the special object information, the object information "substation 1 equipment area 1 device ic phase" at the top of the added sort order among the plurality of pieces of object information thus determined, and proceeds to step S205.
Step S205, transmitting the thermal image data obtained by shooting by the shooting part 1 to the temporary storage part 6; the image processing part 2 carries out pseudo-color processing on the thermal image data shot by the shooting part 1 to obtain image data of the infrared thermal image, and the image data is stored in the temporary storage part 6.
In step S206, the subject indication information obtained from the special subject information and the infrared thermography are simultaneously displayed on the display 4.
In step S207, the control unit 10 determines whether or not a predetermined instruction operation (e.g., pressing of a record key) is performed, and if not, repeats the steps of steps S205 to S207, and if so, proceeds to step S208. A predetermined instruction operation for completing recording and switching by one-touch operation is realized, and the control unit 10 may be configured to perform the predetermined instruction operation based on a predetermined condition; for example, when it is determined that a predetermined time interval is met, for example, when a temperature value in the thermal image exceeds a predetermined threshold value, for example, when a predetermined condition such as a trigger signal of another sensor device connected to the thermal image device 13 is detected, the following procedure is automatically performed even if there is no predetermined instruction from the operating unit 11. The predetermined condition includes that, even if the operation of the operation unit 11, for example, a recording instruction operation, is performed, the following steps are performed when other predetermined conditions are simultaneously satisfied, for example, a predetermined time interval is satisfied, or a temperature value in the thermal image exceeds a predetermined threshold value. Obviously, the prescribed condition may be various conditions configured in advance.
Step S208, recording processing.
The control unit 10 associates and records predetermined infrared data with information on designated subject information "substation 1 equipment area 1 equipment ic phase"; the recording process is similar to that described in example 1 and will not be repeated. And then proceeds to step S209.
In step S209, the control unit 10 determines whether or not the task is completed.
If the operation is finished, the information indicates that the shooting in the shooting mode is finished, the thermal image device 13 returns to the standby state, and the user waits for the operation in other modes. If not, the process returns to step S204, and switches the designated special object information based on the sort order added to the object information determined by the task determination unit.
Specifically, in one embodiment, the information specification unit (control unit 10) adds 1 to the serial number of the sorting order corresponding to the specific object information specified before the switching, and then determines whether the last one of the sorting orders is completed, if not, searches for the object information corresponding to the sorting order serial number obtained by adding 1 to the sorting order serial number (among a plurality of object information determined by the task determination unit shown in fig. 15), specifies the searched object information as the specific object information, and if not, continues adding 1 and continuing the search until the searched object information is found; and so on; and when the judgment is finished, ending.
In another embodiment, the determined object information is added with the serial numbers of 1, 2 and 3 … temporarily according to the sequence order, then the serial number of the appointed object information before switching is added with 1, whether the last one of the temporary serial numbers is finished is judged, if not, the corresponding object information after adding 1 with the serial number is searched and designated as special object information, and if the judgment is finished, the operation is ended. Similarly to embodiment 1, it is not essential to determine whether or not the designation of the last object information is completed.
Returning to step S204, the information specifying unit switches the specified special object information based on the sort order added to the object information specified by the task specifying unit.
Wherein the specified special subject information is switched; in a preferred embodiment, the information specifying unit switches the single object information specified as the special object information from the single object information "substation 1 equipment area 1 equipment ic phase" specified before switching as the special object information to the next object information "substation 1 equipment area 1 equipment ib phase" in the sorting order sequence (the sorting order sequence of the object information determined by the task determining unit) of the object information specified before switching as the special object information.
Further, the information specifying unit switches the single object information specified as the special object information from the object information specified before switching as the special object information to the object information that is one of the object information specified before switching in the sorting order sequence (the sorting order sequence of the object information determined by the task determining unit). The switching is performed based on the sorting order, which may be the order of the sorting order sequence or the reverse order.
Further, when the information specifying section specifies the subject information as the special subject information as two or more pieces of subject information adjacent in order; the information specifying unit changes the specified specific number of pieces of the object information to be sorted adjacent to each other, which is specified before the change, from the specified specific number of pieces of the object information to be sorted adjacent to each other, which is specified before the change, to the specified specific number of pieces of the object information to be sorted adjacent to each other, which is starting from the next piece of the object information to be specified before the change in the sorting order sequence (the sorting order sequence of the object information specified by the task specifying unit). Further, there may be a case where switching is performed in the reverse order.
In this embodiment, when the user finishes shooting the device i in the device area 1, the user will go to the device i in the device area 3, and avoid searching the device i in the device area 2, as shown in the shooting paths of the device areas 1 (1601), 2 (1602), 3 (1603) in fig. 16, which are changed from L10 in fig. 10 to L16 in fig. 16.
In the embodiment, after entering the information mode, task setting is performed; however, it is also possible to perform task setting alone and then enter the information mode, for example, to record the filter condition or the subject information determined based on the filter condition and the sorting order thereof in the information storage unit for subsequent use. Further, a plurality of task settings may be performed. Further, the filtering condition setting step and the task determining step are set forth in steps, but may be configured to be an immediate progressive process, that is, when one of the filtering conditions is set, the task determining section determines the subject information in accordance with the filtering condition, and when the setting is completed, the task determining section completes the determination of the subject information in accordance with the filtering condition; when the setting is determined, processing proceeds to a specifying step of the special subject information. It is obvious that many more embodiments can be obtained by different combinations.
Further, in the present embodiment, there is a single key (e.g., recording key) configured to perform a prescribed instruction operation (representing that the recording instruction operation and the switching instruction operation are the same operation), and a corresponding control program, and in response to the prescribed instruction operation (e.g., the same operation) or prescribed condition of the key, the control section 10 continuously performs control of the recording process of step S208 and the switching process of step S209; the operation is simpler. In this embodiment, recording processing is performed first, and then switching processing is performed, for example, "i C phase of equipment in equipment area 1 of substation 1" is recorded first, and then "i B phase of equipment in equipment area 1 of substation 1" is switched; however, the switching process may be performed first, that is, the switching process is performed to "substation 1 equipment area 1 device ib phase", and then the specified special subject information "substation 1 equipment area 1 device ic phase" before the switching process is associated with the specified infrared data and recorded; the recording unit may be configured to record predetermined infrared data in association with information on the specified special subject information in response to a recording instruction operation or according to predetermined recording conditions.
In order to correctly describe the internal working principle and steps, a step-by-step description mode is adopted in the embodiment, but in the actual implementation process, different embodiments can be adopted for facilitating the operation of a user, for example, based on the same (secondary) operation and/or according to the specified conditions, the actions of recording and switching are continuously carried out, so that the operation is more convenient, the same operation is for example the same operation action of the same key, and the same operation action can complete a plurality of steps (such as completing the recording indication operation and switching indication operation) described above; for example, different operation actions (such as half-pressing and full-pressing) in the same operation on the same key, where the different operation actions in the same operation implement one or more steps described above respectively (such as completing the recording indication operation and the switching indication operation respectively, or completing the recording indication operation and the switching indication operation simultaneously); for example, the operation actions of different keys within a specified time (e.g., the recording instruction operation and the switching instruction operation can be completed separately, or the recording instruction operation and the switching instruction operation can be completed simultaneously). Further embodiments can be obtained by performing different combinations of configurations such as a switching instruction operation and a recording instruction operation (for example, a combination of functions such as a key function and an operation). The operation is not limited to the key, and may be performed by other operation means such as a touch panel.
Preferably, the thermal infrared imager further includes a freezing control unit having a freezing control unit for performing freezing display of the thermal infrared image in response to a freezing instruction operation or in accordance with a predetermined freezing condition. For example, when a record key (assumed to be configured to perform a freeze instruction operation first) is pressed, freeze display of the infrared thermal image is performed (a freeze display step is provided before the recording processing step), and the user can confirm recording of the infrared thermal image and then perform recording to ensure shooting quality. Further, the control unit 10 may be configured to perform freezing under other predetermined freezing conditions; for example, when it is determined that a predetermined time interval is met, for example, a temperature value in the thermal image exceeds a predetermined threshold value, or when a predetermined freezing condition such as a trigger signal of another sensor device connected to the thermal image device 13 is detected, the freezing process is automatically performed even if the freezing operation of the operating unit 11 is not performed. The predetermined freezing condition is, for example, such that the freezing process is performed when other predetermined conditions, such as a predetermined time interval, a temperature value in the thermal image exceeding a predetermined threshold value, and the like, are simultaneously satisfied even if the freezing operation of the operation unit 11 is performed. Obviously, the freeze instruction operation can be combined with the configurations such as the switch instruction operation and the record instruction operation to obtain more embodiments. The operation is not limited to the key, and may be performed by other operation means such as a touch panel.
As described above, by setting the filtering condition of the subject information in the shooting task, the display of redundant information can be reduced, the displayed subject indication information is more instructive, the shooting path is simplified, and the purposes of reducing strength, improving efficiency and avoiding omission are achieved. Obviously, when various filtering conditions are set, great convenience is brought to shooting of a user. If the object information has the attribute information of the history (such as the past defect situation), the user can quickly find the related information of the defect object by inquiring the defect situation, thereby being convenient for the retest. The operation is made simpler by a single key configured to represent both the recording and switching operations. Example 2 is a preferred embodiment, although it is not necessary that all of the above advantages be achieved simultaneously in any one product that embodies the invention.

The thermal image processing device 100 may be, for example, a computer or a dedicated processing device. The thermal image processing device 100 receives thermal image data output by the thermal image acquisition device 101 connected with the thermal image processing device 100 through the communication interface 1 based on the control of the CPU 8. The communication interface 1 is used for continuously receiving thermal image data output by the thermal image acquisition device 101; the method comprises the steps of receiving thermal image data (transmitted by a relay device through thermal image data output by a thermal image acquisition device 101) transmitted by the relay device; meanwhile, the thermal image acquisition device can also be used as a communication interface for controlling the thermal image acquisition device 101. Here, the communication interface 1 may be various wired or wireless communication interfaces on the thermal image processing apparatus 100, such as a network interface, a USB interface, a 1394 interface, a video interface, and the like. The auxiliary storage unit 2 is a storage medium such as a CD-ROM or a memory card, and a related interface. The display control unit 3 displays a display image on the display unit 4 under the control of the CPU 8. The display unit 4 may be a liquid crystal display, or the thermal image processing apparatus 100 may have no display in its own electrical structure. The hard disk 5 stores therein a program for control and various data used in the control. The temporary storage 6, such as a volatile memory, e.g., a RAM, a DRAM, or the like, functions as a buffer memory for temporarily storing thermal image data received by the communication interface 1, and functions as a work memory for the CPU 8. The operation unit 7: for the user to operate. The CPU8 controls the overall operation of the thermal image processing apparatus 100 and performs various related processes. For example, the received thermal image data is subjected to predetermined processing such as correction, interpolation, pseudo color, synthesis, compression, decompression, and the like, and converted into data suitable for display, recording, and the like. For example, when the received thermal image data is compressed thermal image AD data, the predetermined processing, such as the CPU8, decompresses the thermal image data received by the obtaining part and performs corresponding pseudo color processing; for example, when the received thermal image data itself is the image data of a compressed infrared thermal image, the image data of the infrared thermal image is decompressed to obtain the image data of the infrared thermal image. For example, when the communication interface 1 receives an analog thermal infrared image, image data of a digital thermal infrared image is obtained after AD conversion by the relevant AD conversion circuit.
The thermal image capturing device 101 includes a communication interface 10, an image capturing unit 20, a flash memory 30, a temporary storage unit 50, an image processing unit 40, and a CPU 60.

Therefore, the description of the embodiments is omitted. Obviously, the thermal image processing device 100 can be used with various thermal image acquisition devices having a thermal image shooting function, such as various handheld thermal image devices.

Preferably, the shot indication information and the continuous infrared thermal images are displayed simultaneously; for example, when a display instruction of predetermined specially displayed subject instruction information is received, the subject instruction information and the frozen infrared thermal image may be displayed simultaneously; or the display control unit may switch the display infrared thermal image to display the object indication information obtained according to the special object information specified by the information specifying unit in a special display manner in response to the display indication of the object indication information (for example, pressing a key representing the object information display); and then, switching operation can be carried out, the indication information of the shot object after switching is particularly displayed, and when the display indication of the infrared thermal image is responded, the infrared thermal image is displayed. After the special display, the display may be blanked after a predetermined time or based on a user operation to avoid occupation of the display screen. Further, the plurality of pieces of subject instruction information displayed in the sort order may be selected by the user without performing the switching operation, and the information specifying unit may specify, based on the selection by the user, subject information as the special subject information; in this way, since the subject instruction information is displayed in the order of the order added to the subject information, the user can select the subject instruction information easily and clearly, and the present invention is also configured. It is obvious that when the infrared recording apparatus of the present invention is used as a part of a thermal imaging apparatus, the display control section can be omitted and the present invention is also constituted.
