Embodiment
Referring to Fig. 1, a kind of coding type position detecting device with fault self-diagnosis, comprise the message identification board 24 that is loaded on detected position, detecting sensor 20 and the control device on the mobile apparatus, positional information Sign Board 24 comprises a group id bar that contains locating information sign indicating number and coded message sign indicating number, one group id bar comprises a positioning mark bar 26 and many code identification bars 27, positioning mark bar 26 is shorter than code identification bar 27, positioning mark bar and code identification bar left-right symmetric.Corresponding detecting sensor 20 comprises an alignment sensor 22 and many code sensors 23.Fixed frame 21 is housed on the mobile apparatus, detecting sensor 20, logical operation circuit 25, position indicator 15, fault detect attention display 18, reset switch 16 and selector switch 17 are housed on the fixed frame 21, detecting sensor 20 output connects logical operation circuit 25, after logical operation circuit 25 computings with signal input position display 15, fault detect attention display 18 and mobile apparatus master controller 19.
Fig. 2 is the circuit connection diagram of logical operation circuit 25.Logical operation circuit 25 is accepted the location and the coded signal input treated output in back of detecting sensor 20.
When having the coding type position detecting device work of fault self-diagnosis, be installed on the mobile apparatus fixed frame 21 by alignment sensor 22, detecting sensor that code sensor 23 is formed 20 moves with mobile apparatus, and do relative motion with fixing positional information Sign Board 24, when detecting sensor 20 does not have in-position message identification board 24, all detecting sensors 20 all do not have signal output, promptly complete " 0 " state, in the time of in detecting sensor 20 in-position message identification board 24 scopes, detecting sensor 20 detects one group of sign bar that comprises location and coded message on the positional information Sign Board 24, can export various status signal, through on position indicator 16, showing the current position that arrives of mobile apparatus after the computing of logical operation circuit 25.Will on fault detect attention display 17, show failure alarm signal if there is any one sensor to break down in the detecting sensor 20.Logical operation circuit 25 outputs to signal mobile apparatus master controller 19 simultaneously, is controlled by the action of 19 pairs of mobile apparatus of master controller.
Referring to Fig. 3, comprise on the positional information Sign Board 24 by a positioning mark bar 26 and many group id bars that code identification bar 27 is formed, can give each position encoded.The number of positions of fixed point is selected code identification bar 27 as required, and corresponding code sensor 23 also can be determined.As select five code identification bars, then at most can to 31 position encoded, need select five of code sensors for use, adding an alignment sensor again needs six sensors to get final product altogether.Therefore adopt sensor that coded system can be less to positioning detection than multiposition.
Specific embodiment is seen Fig. 3, Fig. 4.Because positional information Sign Board 24 is symmetrical, therefore, no matter mobile apparatus be move from left to right or turn left from the right side operation, no matter be to withdraw from again or moving stopping behind the in-position, can the normal measuring ability of impact position pick-up unit.
The utility model coding type position detecting device has the function of fault self-diagnosis, referring to Fig. 2, Fig. 3, Fig. 4.Do not have in the scope of in-position message identification board 24 at right 1 position-detection sensor 20, the Z of detecting sensor 20, K0, K1, K2, the equal no signal output of K3, Kn are " 0 " entirely, the output Q of rejection gate 1 is " 1 ", and rising edge flip-flop number 13 count contents are " 1 "; Mobile apparatus drives detecting sensor 20 and moves 2 positions to the right in right 1 position, the Z of detecting sensor 20, K0, K1, K2, K3, the Kn output signal is become non-complete " 0 " and is trended towards complete " 1 " by complete " 0 ", the output Q of rejection gate 1 becomes " 0 " by " 1 ", if the Z of detecting sensor 20, K0, K1, K2, K3, the Kn sensor all moves normally, the Z of detecting sensor 20, K0, K1, K2, K3, the Kn output signal will become " 1 " entirely, rise to " 1 " with the output Q of door 2 by " 0 ", by or door 6 input end 2 make output Q rise to " 1 " from " 0 ", the clear terminal R of enter counter 13 makes count content " 1 " be reset to " 0 ", judge promptly that through complete " 0 " and full one state process all detecting sensor 20 work are good, rest-set flip-flop 9 set that is triggered, circuit enters the preparation of reading location data.
Mobile apparatus drives detecting sensor 20 and moves 3 positions to the right in right 2 positions, when 2 positions, the right side of detecting sensor 20 in-position message identification boards 24 and the edge critical conditions between right 3 positions, alignment sensor 22 output signals on the detecting sensor 20 are because the positioning mark bar 26 on the positional information Sign Board 24 is shorter than code identification bar 27, therefore the variation of alignment sensor 22 signal Z will lag behind code sensor 23 signal K0, K1, K2, K3, the variation of Kn and remain " 1 " makes the input end 1 with door 10 not have wrong position signalling output for guarantee " 0 " by not gate 12; Arrive right 3 positions through critical conditions, the positioning signal Z output of detecting sensor 20 is changed to " 0 " by " 1 ", make with door 10 input end 1 through not gate 12 and to be " 1 ", before be locked as " 1 " by rest-set flip-flop 9 output Q with the input end 2 of door 10, the logical and condition satisfies and door 10 output Q are changed to " 1 " by " 0 ", be triggered Q end of rest-set flip-flop 11 becomes " 1 " input by " 0 " and deposits the C end of decoding scheme 14 data of depositing decoding scheme 14 are refreshed, new position data is by the signal K0 of detecting sensor 20, K1, K2, K3, Kn is from depositing the 1-5 end input of decoding scheme 14, at this moment each code sensor 23 has all entered the code area of positional information Sign Board 24 reliably, signal K0, K1, K2, K3, the output of Kn tends towards stability, there has not been possibility wrong position signalling to occur, the positional information that latchs outputs to position indicator 15 by the Q end of depositing decoding scheme 14 and shows current location, is sent to the purposes such as operation control of mobile apparatus master controller 19 as mobile apparatus simultaneously.
Move 2 positions to the right in right 1 position, rising edge flip-flop number 13 count contents are " 1 ", and the Z of detecting sensor 20, K0, K1, K2, K3, Kn output signal become non-complete " 0 " by complete " 0 ", and the output Q of rejection gate 1 becomes " 0 " by " 1 ".If have one or several actions undesired in the Z of detecting sensor 20, K0, K1, K2, K3, the Kn sensor, detect sensing circuit 20 abnormal sensor output signals and will be maintained " 0 ", can not rise to " 1 " with the output Q of door 2 yet, can not be to the clear terminal R zero clearing of counter 13, count content remains " 1 ", rest-set flip-flop 9 set that can not be triggered, circuit can not the reading location data.
Mobile apparatus drives detecting sensor 20 continuation and moves or return right 1 position in 6 positions to the right, the Z of detecting sensor 20, K0, K1, K2, K3, the Kn output signal becomes " 0 " entirely by non-complete " 0 ", the output Q of rejection gate 1 becomes " 1 " once more by " 0 ", rising edge flip-flop number 13 count contents are added " 1 ", the content of these hour counter 13 countings is " 2 ", the Q end of counter 13 becomes " 1 " by " 0 ", the parts of then representing detecting sensor 20 have fault, and failure message delivers to fault alarm display 18 and mobile apparatus master controller 19 is used for fault alarm, show and control.Fault reset circuit 16 by or the fault-signal of door 1 pair of memory of input end of 6 reset, if the trouble unit of detecting sensor 20 is repaired, mobile apparatus can be reset equally through positional information Sign Board 24 a faults memory.
If selector switch 17 is chosen as connection when logical operation circuit 25 resets, be cleared simultaneously by depositing the positional information that decoding scheme 14 latchs so, the expression mobile apparatus has left the position; If selector switch 17 is chosen as disconnection, be retained by depositing the positional information that decoding scheme 14 latchs so, when the next position Refresh Data, replaced by new location data.
