Open in the flat 1-226685 communique scheme the spy relevant for the device for signalling of elevator.In this communique, illustrated and carried out the device that half duplex operation transmits that shown in the figure, the telltale of elevator also adopts analog structure.But because problems such as propagation delay have in fact adopted the full duplex transmission, simultaneously, in recent years, telltale has also adopted digital.
These structures have been shown among Fig. 3.Wherein, 1 is provided in a side of the control panel in the Machine Room, the 2nd, the microcomputer of interior dress serial transfer interface UART, as the main frame (following slightly waiting space main frame) of waiting space transmission, the 3rd, main frame (the following slightly car main frame that the microcomputer of interior dress serial transfer interface UART transmits as car.In addition, car main frame and waiting space main frame are generically and collectively referred to as main frame).
4 are arranged on the microcomputer (following slightly waiting space extension set) of waiting space, connect digital display device 5, assignment key lamp 6, assignment key 7 etc., and control them.This omission up/descending difference.The 8th, car, 9 are provided in a side of microcomputer (the following slightly car extension set in the car 8.Waiting space extension set and car extension set are referred to as extension set), control cage operating panel 10, digital car telltale 11 etc.
The 12nd, the transmitting line of waiting space main frame, the 13rd, the receiving lines of waiting space main frame, the 14th, the transmitting line of car main frame, the 15th, the receiving lines of car main frame.
Fig. 4 is the transmission figure in the transmission device for elevator signal shown in Figure 3.Wherein, the transmission data of main frame to extension set are represented on top, and the answer data of extension set to main frame are represented in the bottom.Circle A is synchronous for the realization of main frame and extension set is transmitted to circle D, and the nothing that main frame inserted sends the time of data, after extension set detects it, and the synchronous driving of realization and main frame.D1～D16 is the transmission data of main frame, and circle 1～circle 16 is answer data of extension set.
About the dynamic drive method of digital matrix display, opening the spy has scheme to propose in the clear 63-3477 communique.In this communique, the method with hardware driving control LED has been proposed, still, owing to the reduction of microcomputer price, as shown in Figure 5, the method for controlling the LED dot matrix with the microcomputer direct drive becomes possibility in recent years.Fig. 5 shows the example of controlling with waiting space extension set 4.Wherein, the 16th, transmit interface circuit, the 17th, the actuator A of driving data lines, this data line is used to drive the LED19 of digital matrix display 5, and the 18th, the actuator B of driving common line is output as negative logic.
Fig. 6 to Fig. 8 is the diagram of circuit that is contained in the program in the waiting space extension set 4, Fig. 6 is a main program, Fig. 7 is the timing interrupt handling routine that is contained in the extension set 4, and Fig. 8 is the interrupt handling routine of serial transfer, and the part relevant with the driving of digital matrix display 5 only is shown.About car extension set 9, same circuit structure is also arranged, and carry out same processing.
Among Fig. 5, in extension set 4 unshowned inner ROM, write the font data table of address and data in advance, it utilizes the transmitting line of main frame, receives idsplay order by interface circuit 16, and instruction map is become address in the table.
For example, if idsplay order " 1 " shows that in above-mentioned font data table the address (Hex) and the data (Bin) of the font data of " 1 " are set at:
Address (Hex) data (Bin)
0100 00000000
0101 01000000
0102 01111111
0103 01000000
0104 00000000
First address is " 0100 ", makes the timer internal starting, and each timing is finished surely, and with address increment successively, order is exported font data.
That is, for address " 0100～0104 " demonstration " 1 ", must circularly the data in address " 0100 "～" 0104 " be exported to the P2 port.Here, the demonstration sign indicating number of " 010 " expression " 1 " the preceding in " 0100 ", " 0 " followed is formed by the pointer of font data address.In a word, in Fig. 6, X is an address pointer, presets initial value 0(S1), then, the starting timer allows regularly the interruption with serial transfer, wait for and interrupt taking place (S2～S6).
In timing interrupt handling shown in Figure 7, with the X of the LED row data of lighting a lamp, promptly the data of address " 010X " are exported to P2 port (S11), at the X position of P1 output H level (S12).And then, with X increment (S13), in the font data table, do not have the numerical value more than the X=5, therefore, when reaching X=5, X is composed 0, pointer X gets back to 0, return main program (S14, S15).
In serial transfer interrupt handling shown in Figure 8, after finishing serial transfer data handings such as telltale demonstration sign indicating number reception, (S21 S22), returns main program shown in Figure 6 to carry out the answer processing.
Existing elevator display apparatus constitutes as described above, therefore, in waiting space extension set 4 and car extension set 9, the caused interruption of timer of interior dress in caused interruption of serial transfer and the local exchange can take place.
Priority ranking when above-mentioned two interruptions take place simultaneously is, the interruption that timer causes is an override, because when there is deviation the time of dynamic driving, the demonstration of digital display device 5 can be glimmered.
But, if the interruption that causes with timer is an override, will inevitably postpone one section for the answer (circle 1～circle 16 of Fig. 4) of waiting space and car main frame 2,3 and do the regularly time of interrupt handling, in addition, this delay time can since the timing interrupt handling the process of process deviation takes place.
Therefore, main frame 2,3 can not be fixed from the time that extension set 4,9 receives answer, and this is the complicated reason of program of main frame 2,3.If fixing time of reception, then answering is to become indeterminate at which sends that data make, and must outside the data division redundancy bit be set in the answer data, utilize and answer number etc., clearly be which transmission data of main frame are answered, the result, the figure place of answering data has reduced.There is above-mentioned such problem in prior art.
The present invention proposes for addressing the above problem, purpose is to provide a kind of elevator display apparatus, when the digital display device of the serial transfer dynamic driving extension set that utilizes main frame, digital display device does not glimmer, and the cycle that main frame is answered data from the extension set reception also keeps certain.
