(action of code device 100)
The pick up camera 140 that is arranged in lift car outputs to the analog picture signal 2 in the lift car that photographs the A/D converter 101 (S01) of code device 100.And elevator control gear 130 outputs to " elevator information 3 " coder 103 (S02) of code device 100.Here " elevator information 3 " means the digital signal of the real-time motion situation of elevator, for example comprises:
(1) expression car position information,
(2) information of expression car moving direction,
(3) expression elevator faults information,
(4) information of expression car door switching
Deng signal.Comprise which type of information (signal) about " elevator information 3 ", but free setting in the following description, is supposed to comprise these 4 of " information of (1) expression car position "~" information that (4) expression car door opens and closes ".
(processing in code device 100)
Real time simulation picture signal 2 (realtime graphic) in real-time car is imported into A/D converter 101 (S01), is converted into data image signal 4.Data image signal 4 after conversion is imported into frame buffer 102, is temporarily stored (S03).Coder 103 execution are stored in the coding processing of the data image signal 4 in frame buffer 102 and the coding of elevator information 3 is processed, generate " the Image Coding Bit String 5 that comprises elevator information 3 " (example of coded-bit string data), output to decoding device 110.
(coder 103 is according to the situation of JPEG)
Coder 103 (coding section) is for example the coder according to JPEG (Joint Photographic Experts Group, JPEG).In the situation that according to JPEG, coder 103 is by carrying out the coding processing according to JPEG, at first, generate " Image Coding Bit String 5 " (the Image Coding Bit String before the Bit String that inserts elevator information 3) according to the data image signal 4 that is stored in frame buffer 102.
Fig. 3 illustrates coder 103 according to the figure of the Image Coding Bit String 5 of JPEG generation.Image Coding Bit String 5 according to JPEG generates as shown in Figure 3, from start mark 601, continues with section 602, view data 603, finishes at end mark 604.Here, view data 603 is that the data image signal 4 of the image in the car that expression is photographed by pick up camera 140 has carried out the Bit String after the digital compression.For example insert 1 frame that (record) has image in car in the zone of this view data 603.
And, in 6020 sections of being included in 602 of comment field zone.Comment field zone 6020 is zones that the user can use alone.Comment field zone 6020 is made of the segment length 6022 in COM mark 6021, comment field zone (byte number of additional code to comment field+2) and comment field 6023.
(coding schedule 1031)
And as shown in Figure 4, coder 103 has for the coding schedule 1031 that elevator information 3 is encoded (example of predetermined elevator information coding).Coder 103 use coding schedules 1031 carry out the coding of elevator information 3 to be processed.That is, coder 103 uses coding schedule 1031, will
(1) car position information,
(2) moving direction,
(3) elevator faults information,
(4) door switching information
Encode, these Bit Strings after coding sequentially are inserted in the comment field 6023 of the Image Coding Bit String 5 that has generated by this, generate " the Image Coding Bit String 5 that comprises elevator information 3 ".In this case, the elevator information 3 that inserts as Bit String is corresponding to the Bit String of the image in the zone that is inserted into view data 603.That is the elevator information 3 that, is inserted in comment field 6023 is the elevator informations 3 in the moment (moment identical with photography or the moment that approaches) at the image of having taken view data 603.As shown in Figure 3, because section 602 (zone that comprises the Bit String of elevator information) and view data 603 (zone that comprises the Bit String of data image signal) are continuous, thereby by Bit String, the photography elevator information constantly of image in car and this image can be associated.
In car, " related " of the photography of image and this image elevator information constantly can define with the grammer of JPEG or MPEG4.In present embodiment 1, an example as association, as mentioned above, continuous section 602 (zones that comprise the Bit String of elevator information) and view data 603 (zone that comprises the Bit String of data image signal) are associated, yet continuous situation is an example, also can carry out other associations according to the grammer of JPEG or MPEG4.
(the insertion example to comment field in JPEG)
Concrete example below is shown.As elevator information 3, suppose and inputted following encoding bit strings.
(1) car position information: the bottom of building
(2) car moving direction: upwards (UP)
(3) elevator faults information: fault cause 1 and fault cause 3
(4) car door opens and closes information: close door
In these cases, when obtaining encoding bit strings with coding schedule shown in Figure 4 1031, as shown below.
(1) car position information: " 00000000 " (being 00 when using 16 system souvenir),
(2) moving direction: " 00000000 " (being 00 when using 16 system souvenir),
(3) elevator faults information: " 00000101 " (being 05 when using 16 system souvenir),
(4) door switching information: " 11111111 " (being FF when using 16 system souvenir).
Therefore, (1)~(4) can use 16 system souvenirs to be " 000005FF ".
Because the encoding bit strings of COM mark 6021 is " FFFE " (by JPEG regulations), thereby the comment field that is Fig. 6 of additional elevator information 3 to comment field zone 6020 in this case zone 6020.
Coder 103 will " the Image Coding Bit String 5 that comprises elevator information 3 " sends to the decoding device 110 of the handler chamber that is positioned at building via LAN (Local Area Network, local area network) etc.
(processing of decoding device 110)
Decoding device 110 receives " the Image Coding Bit String 5 that comprises elevator information 3 " from code device 100, and it is stored in storage part 112 (S05).Demoder 111 reads in " the Image Coding Bit String 5 that comprises elevator information 3 " that is stored in storage part 112, with its decoding (S06).In this case, the result that demoder 111 will be decoded and be processed, namely decoded picture 7 and elevator information 8 (the decoded information of elevator information 3) output to monitoring device 120.In the situation that coder 12 is according to JPEG, demoder 111 is decoded the Bit String of image according to the benchmark (example of " image decoding corresponding with predetermined Image Coding rule is regular ") according to JPEG.
(decoding of elevator information 3)
In this case, demoder 111 generates decoded picture 7 by carrying out the decoding processing according to the regulation of for example JPEG.And demoder 111 has the decoding table 1111 identical with coding schedule shown in Figure 4 1031 (example of " the elevator information decoding rule corresponding with predetermined elevator information coding rule ").Demoder 111 passes through with reference to decoding table 1111, the decoding that carry out in " the Image Coding Bit String 5 that comprises elevator information 3 ", is included in the encoding bit strings of the elevator information 3 in comment field 6023 is processed, and elevator information 8 (decoded elevator information) is outputed to monitoring device 120.That is, demoder 111 in the situation that the decoding of the encoding bit strings of elevator information 3 process, according to
(1) car position information,
(2) moving direction,
(3) elevator faults information,
(4) door switching information
Order, use the decoding table 1111 of Fig. 4 to decode.
(action of monitoring device)
Decoded picture 7 and elevator information 8 are output to monitoring device 120 from decoding device 110.Fig. 5 illustrates an example of the picture of monitoring device 120 demonstrations.As shown in Figure 5, do not show overlappingly respectively decoded picture 7 and elevator information 8 on the picture of monitoring device 120.In Fig. 5, show 201 expression floors, following 3 of figure 202 expression:
(1) car position information: 1 layer,
(2) moving direction: upwards (UP),
(3) close a state.
And, show 203 expression failure messages, namely occur " fault cause 1 " and " fault cause 3 ".And, video in the car of the cab interior that image 204 expressions are current.According to such demonstration, in car, video can not hidden by the demonstration of elevator information (elevator operational situation), easily sees.And, only carry out the decoding of " comprising the Image Coding Bit String 5 of elevator information 3 " processes due to demoder 111, thereby do not need to carry out the related special cell of view data and elevator information, the elevator information 8 that can easily obtain decoded picture 7 and link with decoded picture 7.Like this, can use simple structure easily to show decoded picture 7 and the elevator information 8 that links with decoded picture 7.
(coder 103 is according to the situation of MPEG4)
And coder 103 can be also for example the coder according to MPEG4 (Moving Picture Experts Groups, Motion Picture Experts Group 4).Fig. 7 is illustrated in coder 103 and has carried out " the Image Coding Bit String 5 " that generates in the situation of coding processing according to the regulation (example of predetermined Image Coding rule) of MPEG4.In (n-1) individual view data 401 and (n) individual view data 402 shown in " the Image Coding Bit String 5 " of Fig. 7.(n-1) individual view data 401 is the images that first photograph.For example, (n) individual view data 402 is made of header information 801 (example in zone that comprises the Bit String of elevator information) and view data 802 (example in zone that comprises the Bit String of data image signal).Header information 801 and view data 802 are continuous zones.For example insert 1 frame that (record) has image in car in the zone of view data 802.Perhaps, also can record a plurality of frames in the zone of view data 802.The interior frame number in zone that is inserted into view data 802 depends on installation.The same with the situation of JPEG, coder 103 has coding schedule shown in Figure 4 1031 (example of elevator information coding rule).Then, coder 103 uses coding schedules 1031, carries out the coding of the elevator information 3 inputted and processes.In the zone of the customer data 8022 of the user data area 8020 that coder 103 exists in the Image Coding Bit String 5 (Fig. 7) that has generated, according to
(1) car position information,
(2) moving direction,
(3) elevator faults information,
(4) door switching information
Order, insert each encoding bit strings after coding, generate " the Image Coding Bit String 5 that comprises elevator information 3 ".In this case, be inserted into the encoding bit strings of the elevator information 3 in the zone of customer data 8022 corresponding to the Bit String of image in the zone that is inserted into view data 802.That is the elevator information 3 that, is inserted in customer data 8022 is the elevator informations 3 in the moment (moment identical with photography or the moment that approaches) at the image of having taken view data 802.Equally, the elevator information 3 that is inserted in header information 701 is the elevator informations 3 in the moment (moment identical with photography or the moment that approaches) at the image of having taken view data 702.
Fig. 8 illustrates the concrete example of " the Image Coding Bit String 5 that comprises elevator information 3 " in user data area 8020.The zone that user data area 8020 is included in header information 801 and the user can use alone.User data area 8020 is after being connected on customer data initial code 8021 and the structure of additional user data 8022.As elevator information 3, suppose to be
(1) car position information: the bottom of building,
(2) moving direction: upwards (UP),
(3) elevator faults information: fault cause 1 and fault cause 3,
(4) door switching information: close door.
In this case, because the encoding bit strings of customer data initial code is " 000001B2 " (by MPEG4 regulation), thereby user data area in this case 8020 is signal shown in Figure 8.
(graphicinformation and elevator information related)
Fig. 9 generates the concept map of " the Image Coding Bit String 5 that comprises elevator information 3 " with the meaning explanation coder 103 of confirming again.Pick up camera 140 is that analog picture signal 2 continuous wave outputs are to A/D converter 101 with the current vision signal (realtime graphic) that photographs in car.A/D converter 101 is converted to the analog picture signal 2 of continuous wave output successively data image signal and outputs to coder 103.On the other hand, elevator control gear 130 is that current elevator information 3 continuous wave outputs are to coder 103 with digital signal.Elevator information 3 means the information (information of expression real-time motion situation) of the current operational situation of elevator.Shown in Figure 9, the information of the direction of arrow first is imported into coder 103.As shown in Figure 9, analog picture signal 2 is converted into data image signal 4 and is input to coder 103.The data image signal 4 that coder 103 will be inputted continuously is converted to Image Coding Bit String 5, and will be inserted in the presumptive area of Image Coding Bit String 5 elevator information 3 information after the Bit String of having carried out.(n-1) 401 of Fig. 9 and (n) 402 expressions as view data 401 and the data image signal 4 after view data 402 codings and the parts of elevator information 3 of Fig. 7.That is, in (n-1) 401, at the data image signal 4 in the roughly the same moment and elevator information 3 by Bit String.(n) 402 that becomes image in car subsequently is also the same with (n-1) 402.That is, for elevator information 3 and analog picture signal 2, current real time information is input to code device 100 continuously.And 4 conversion is instantaneous from analog picture signal 2 to data image signal.Therefore, coder 103 is by carrying out Bit String in timing shown in Figure 9 to data image signal 4 and elevator information 3, do not need special device, the moment and the elevator information (that is, elevator operational situation) in this moment of having taken the image in the car can be associated.
(demoder in MPEG4)
And in this case, the demoder 111 of decoding device 110 is the demoders according to MPEG4.That is, demoder 111 is decoded the Image Coding Bit String according to the regulation (with an example of " the image decoding rule that predetermined Image Coding rule is corresponding ") according to MPEG4.And demoder 111 is identical with the situation of JPEG, uses decoding table 1111 (example of " the elevator information decoding rule corresponding with predetermined elevator information coding rule ") that the encoding bit strings of elevator information 3 is decoded.Like this, demoder 111 carries out being processed by the image decoding of MPEG4 regulation, not only export decoded picture 7, but also the decoding of carrying out the encoding bit strings of the elevator information 3 that comprises in customer data 8022 in " comprising the Image Coding Bit String 5 of elevator information 3 " with coding schedule 1031 processes, and elevator information 8 is outputed to monitoring device 120.The action of monitoring device 120 is identical with the situation of JPEG.
(reproduction of past image)
With reference to Figure 10, illustrate by the recreate the past situation of image of decoding device 110.In the situation that Figure 10 supposes and utilizes MPEG4.In Figure 10, compared to Figure 1, code device 100 has clock and watch section 104, and decoding device 110 has data extraction unit 113.
(code device 100)
Clock and watch section 104 has instrumentation current date and clock function constantly.Clock and watch section 104 will represent that the digital signal of current date is that the date information output is to coder 103.For example 104 outputs of clock and watch sections for example " 2007.11.17,14:32:56 " as date and time information (representing on November 17th, 2007,14: 32: 56).Coder 103 when generating above-mentioned " the Image Coding Bit String 5 that comprises elevator information 3 ", inserts date and time information when having inputted in the situation of date and time information from clock and watch section 104.For example in the situation that MPEG4, coder 103 is inserted into date and time information in the header information of header information shown in Figure 7 701, header information 801 etc.Thus, be inserted into the interior view data of view data 702 corresponding to the date and time information that is inserted in header information 701, be recorded in the interior view data of view data 802 corresponding to the date and time information that is recorded in header information 801.Coder 103 will be inserted with date and time information " the Image Coding Bit String 5 that comprises elevator information 3 " (below be sometimes referred to as with date and time information Bit String) and output to decoding device 110.

In elevator monitoring arrangement 1000, because demoder 111 decodes " the Image Coding Bit String 5 that comprises elevator information 3 " be presented on monitoring device 120, thereby can not show overlappingly image in elevator information and car.
In elevator monitoring arrangement 1000, according to any one rule in JPEG and MPEG4, thereby have rule now by utilization due to coder 103 and demoder 111, can be with the simple structure implement device.
In elevator monitoring arrangement 1000, coder 103 use coding schedules 1031 are encoded elevator information.Therefore, can set neatly elevator information with coding schedule 1031.
In elevator monitoring arrangement 1000, elevator information 3 comprises the information of information, expression elevator faults of the information that represents car position, expression car moving direction and any one information at least in information that the expression car door opens and closes.Therefore, these information important concerning elevator monitoring can be presented on monitoring device 120 and not with car in the doubling of the image.
As previously discussed, such elevator monitoring arrangement has been described, is provided with pick up camera 140 in lift car, show the image of described pick up camera 140 when showing the elevator operative condition, this elevator monitoring arrangement has:
Code device 100, it carries out digitalisation to the image that described pick up camera 140 photographs, when the coding that carries out the view data after digitalisation with Image Compression is afterwards processed, by encoding from the information (elevator information) that control board for elevator obtains in the lump, output comprises the encoding bit strings of elevator information and view data;
Decoding device, it decodes view data and elevator information simultaneously from described encoding bit strings; And
Telltale, it shows that decoded result is decoded picture and elevator information.
According to described structure,
(1) by the encoding bit strings of insertion elevator information in the zone that namely image quality of decoded picture is not exerted an influence by the zone of Image Compression regulation, carry out related with at the elevator information in the moment of having taken view data of view data.Therefore, do not need that elevator information is overlapped and be shown on decoded picture on telltale.Therefore, building management person can confirm integral status in car.
(2) by processing that 1 encoding bit strings is decoded, can obtain simultaneously view data and at the elevator information in the moment of having taken view data.Therefore, need to be in order not carry out the related needed special cell of view data and elevator information.Therefore, can be by simple structure display image data and at the elevator information in the moment of having taken view data easily.
