Below, with reference to Fig. 6 to Fig. 8 the structure and the action of the comparator circuit that uses in repeater in the communication in elevator of present embodiment are described.
Fig. 6 is illustrated in the diagram of block of the communication in elevator of one embodiment of the present invention with the structure of the comparator circuit that uses in the repeater.Need to prove that in Fig. 6, the part identical with Fig. 2 adopts the symbolic representation identical with Fig. 2.Fig. 7 is illustrated in the diagram of circuit of the communication in elevator of one embodiment of the present invention with the action of the comparator circuit that uses in the repeater.Fig. 8 is illustrated in the sequential chart of the communication in elevator of one embodiment of the present invention with the action of the comparator circuit that uses in the repeater.
In the present embodiment, the content by 18 pairs of data of comparator circuit compares.
At this, whether the data content comparator is configured to that 2 input data that are transfused to are carried out " AND " and handles, but consistent as long as finally can judge 2 input data, then also can adopt additive method.
Below, with reference to Fig. 7 and Fig. 8 the action of comparing circuit 18 is described.
At first, in step S401, repeated direction detector 29 detects the direction of relaying according to enabling signal 27-2,27-4.
Then, in step S402, judge by repeated direction detector 29 whether repeated direction is the direction of order wire 8-1 to order wire 8-2.When being order wire 8-1, enter step S403a in repeated direction to the direction of order wire 8-2, when the result who judges whether regularly, enter step S403b.
At this, the essentiality of the direction of detection relaying is described with reference to Fig. 8.Can be poor between data 15-1 that receives by acceptor circuit 13-1 and the data 15-2 that sends and receive by acceptor circuit 13-2 by transtation mission circuit 14-2 because of the delay generation time in the circuit.For example, in the example of Fig. 8, the meeting generation time is poor between the quantitative data input t12 finish time of the quantitative data input t11 finish time of data D1a and data D1b.Therefore, if compare according to the moment of the some quantitative data inputs in above-mentioned two data to data content comparator 32, whether two data using in the time of then can't judging comparison are correct data.For example, when the moment, t11 compared, be actually data D2a and data D1b are compared.At this moment, if know repeated direction, then for example shown in the image pattern 8 like that, in data from order wire 8-1 during to order wire 8-2 relaying, because data 15-1 is input data content comparator 32 earlier, can implement at the quantitative data input t12 finish time, t22 so can know comparison in advance, rather than implement at the quantitative data input t11 finish time, t21.
In addition, Fig. 8 is described from the occasion that order wire 8-1 is relayed to order wire 8-2 data, and in data when order wire 8-2 is relayed to order wire 8-1, even do not having under the situation of relay data, also only need to change the input sequence when being input to data memory 30.
Below, turn back to Fig. 7 and describe.When the relaying direction is when order wire 8-1 is relayed to the direction of order wire 8-2, in step S403a, receive data 15-1 or test data 20-1 by data memory input 30 inputs.
Then, if know repeated direction,, therefore, behind this quantitative data input, in step S404a, time meter 31 is picked up counting just can know the input earlier of which data.
Then, in step S405a, judge whether timer 31 has surpassed time limit Δ t.If do not go beyond the time limit Δ t, then enter step S406a, if surpassed time limit Δ t, then enter step S409a.Setting like this is the consideration that has not received the occasion of data for the somewhere owing to repeater has been taken place the broken string grade fully.When having surpassed time limit Δ t, be judged as fault has taken place, in step S409a, by data content comparator 32 output breakdown signals 28.
In addition, time limit Δ t was set at more than the delay time that produces between transtation mission circuit 14-2 and the acceptor circuit 13-2, and in the time that arrives next quantitative data input.
Then, in step S406a, the reception data 15-2 that data memory input 30 input backs arrive.
Then, in step S407a, 32 pairs of 2 data of data content comparator compare, and in step S408a, judge whether both comparative results are consistent, if inconsistent, then in step S409a, by data content comparator 32 output breakdown signals 28.
In addition, be when order wire 8-2 is relayed to the direction of order wire 8-1 in repeated direction, in step S403b～step S409b, carry out and processing that step S403a～step S409a is identical.
Below, with reference to Fig. 9 to Figure 11, another structure and the action of the comparator circuit that uses in repeater in the communication in elevator of present embodiment described.
Fig. 9 is illustrated in the diagram of block of the communication in elevator of one embodiment of the present invention with another structure of the comparator circuit that uses in the repeater.Need to prove that in Fig. 9, the part identical with Fig. 2 adopts the symbolic representation identical with Fig. 2.Figure 10 is illustrated in the diagram of circuit of the communication in elevator of one embodiment of the present invention with another action of the comparator circuit that uses in the repeater.Figure 11 is illustrated in the sequential chart of the communication in elevator of one embodiment of the present invention with another action of the comparator circuit that uses in the repeater.
In the present embodiment, the variation that comparator circuit 18A is provided with paired data compares.
Below, with reference to Figure 10 and Figure 11 the action of comparing circuit 18A is described.
At first, in the step S501a of Figure 10, detect the variation edge of input data 15-1 by data variation edge detector 37-a.When the change detected edge, as shown in figure 11, the variation edge of the rising of detection data 15-1 and the variation edge of decline.But also can only change the edge to one of them detects.
Then, in step S502a, 38-a counts this number of edges by the number of edges counting machine.
Equally, in step S501b, the variation edge of input data 15-2 is detected by data variation edge detector 37-b.
Then, in step S502b, 38-b counts this number of edges by the number of edges counting machine.
After this, in step S503, compare by the number of edges of 39 pairs of 2 incoming signals of number of edges comparator.But, as mentioned above, because these 2 input data have the time difference, so only the moment t3 when the end of input (EOI) of two data can carry out correct comparison.
For this reason, in step S505, constantly the comparative result during t3 is inconsistent if end of input (EOI) detector 40 detects end of input (EOI), then in step S506, by number of edges comparator 39 output breakdown signals 28.
At this, if the coding of input data adopts the NRZ signal, and carry out even parity with asynchronous system, then " H " level can not continue 9 more than the bit, therefore, end of input (EOI) detector 40 can be arranged to the circuit that " H " level is detected.In addition, if data are to be the signal of unit change with 1 bit, then end of input (EOI) detector 40 can be arranged to the circuit that its bit number is counted.Whether its result finishes as long as finally can understand quantitative data input.In addition, unit relatively can be a byte, can be word, also can be bag.
Below, with reference to Figure 12 and Figure 13 the structure and the action of the communication circuit 17 used in repeater in the communication in elevator of present embodiment are described.
Figure 12 is illustrated in the diagram of block of the communication in elevator of one embodiment of the present invention with the structure of the communication circuit of using in the repeater.In Figure 12, the part identical with Fig. 2 adopts the symbolic representation identical with Fig. 2.Figure 13 is illustrated in the diagram of circuit of the communication in elevator of one embodiment of the present invention with the action of the communication circuit of using in the repeater.
Below, to receiving breakdown signals 28 by communication circuit 17 and the structure that breakdown signal 28 is notified to main communication terminal 3 being described.
As shown in figure 12, communication circuit 17 has on off controller 43, address setting device 42 and transceiver 41, this on off controller 43 is used to control the switch 24 of order wire switching part 23 shown in Figure 2,42 pairs of employed addresses of this address setting device are set, and this transceiver 41 is given main communication terminal with signalling trouble.
Below, back to signalling trouble is described to the contents processing till the main communication terminal 3 with reference to Figure 13 to receiving breakdown signal 28.
At first, in step S601, after receiving breakdown signal 28, set employed address by address setting device 42.This moment employed address be allocate in advance to the address of the order wire 8-2 bonded assembly communication terminal 6-21～6-2n of the primary side of repeater 17 in some addresses.In the present embodiment, do not distribute the address for repeater.Be that when for example the address was 4 bits, then the quantity of operable address was 16 specifically.The address is assigned to elevator lobby communication terminal 6-11～1n, 6-21～2n, lift car communication terminal 6-c, group office terminal 6-g and the maintenance terminal 6-h etc. of main communication terminal 3, control usefulness, at this moment, if distribute the address for repeater, then can will reduce with order wire bonded assembly terminal quantity.Therefore, being arranged to is that repeater is distributed the address, in repeater fault has taken place simultaneously and need carry out signalling trouble the time, and using the primary side terminal of allocating in advance to repeater is some addresses in the address of communication terminal 6-21～6-2n.In addition, employed address can be pre-set at the very start, also can be arranged to detect and order wire 8-2 bonded assembly communication terminal 6-21～2n by reception data 15-2 is resolved, and sets employed address with this.
Then, in step S602, on off controller 43 outputs switch to switch 24 control signal 22 of order wire 21.
Then, after switch switches, in step S603, use order wire 21 fault to take place to main communication terminal 3 reports by transceiver 41.
In addition, the data that fault for example expression can have been taken place are arranged to obsolete data value under the normal circumstances is changed into " 1111 " for the bit of " 0000 ", thus, carry out failure report.
As mentioned above, according to present embodiment, can when normal control is communicated by letter, implement trouble diagnosing with simple structure, and can give main communication terminal signalling trouble.
In addition, by using the data in the relaying, can when implementing, normal control communication carry out trouble diagnosing.
And, or not control communication normally the time, also can be by carrying out trouble diagnosing from test signal transtation mission circuit output test signal.
In addition, when needing to use the address for the repeater of determining the notice fault, the address of the primary side bonded assembly terminal of use and repeater, thus, then do not need to distribute inherent address, can not reduce and to increase function from fault to main communication terminal that notify under the situation of bonded assembly communication terminal quantity for repeater.
