(a) when data are transmitted
The flow chart of processing movement when Fig. 4 is the data transmission for showing the progress of elevator control gear 10.
Here, elevator control gear 10 is set as transmission master device, by carriage control device 30 and boarding place control device
40 are set as transmission from device, it is contemplated that transmit various letters related with the operating of elevator from transmission master device to transmission from device data
Number the case where and be illustrated.
Firstly, from the transmission control unit 12 of the elevator control gear 10 as transmission master device to work in the operating of elevator
It is related with the operating of elevator certain from the transmission of the carriage control device 30 or 40 data of boarding place control device of device for transmission
Signal (step A10).
At this point, the process processing unit 14 in transmission control unit 12 is referring to transfer management table T1 (step A11) shown in Fig. 3,
Judge whether the signal transmitted has been set to confirmation response (step A12).
In the case where being set to the signal without confirmation response ("No" of step A12), process processing unit 14 is in data
What does not do especially after transmission, terminates processing herein.Such as sound output signal, the display output of different degree 1 shown in Fig. 3
Signal is the setting without confirmation response, so what does not do especially after data transmission.This is because even if for some reason and
Signal is not conveyed normally, and the operating of elevator there will not be big obstacle.
On the other hand, in the case where being set to confirmation response ("Yes" of step A12), process processing unit 14 is executed
Such processing below.
That is, returning to the signal really from the carriage control device 30 or boarding place control device 40 of device from as transmission
When recognizing response ("Yes" of step A13), process processing unit 14 is confirmed whether to detect exception (step by transmission abnormality test section 17
A14).In the case where confirmation response detects certain exceptions ("Yes" of step A14), process processing unit 14 is as reception mistake
To handle (step A15).
In addition, not returning to confirmation sound from the carriage control device 30 or boarding place control device 40 of device from as transmission
In the case where answering ("No" of step A13), process processing unit 14 judge whether from data transmit the signal by it is scheduled when
Between ta (step A16).If responding even across above-mentioned time ta still without confirmation, process processing unit 14 is used as time-out error
It handles (step A17).
(b) the case where transmission abnormality has occurred
Fig. 5 and Fig. 6 is to show to be moved by the processing having occurred in the case where transmission abnormality that elevator control gear 10 carries out
The flow chart of work, shows including above-mentioned reception mistake, time-out error etc. and that certain transmission have occurred in data transmission is different
Processing movement in the case where often.
When detecting transmission abnormality by the transmission abnormality test section 17 in process processing unit 14 ("Yes" of step B10),
Process processing unit 14 confirms the different degree (step B11) of the signal referring to transfer management table T1 shown in Fig. 3.
For the signal of different degree 3 ("Yes" of step B12), the confirmation of process processing unit 14 is examined by transmission abnormality
Whether the communication number of retries for the signal that the retryCounter 18a in survey portion 17 is counted has reached upper limit value α (step B13).?
In the case that the communication number of retries of the signal has reached upper limit value α ("Yes" of step B13), process processing unit 14 passes through communication
The abnormity detection portion 18b that retries for retrying control unit 18 notifies the mistake that retries of the signal and to storage to operation control section 11
Register (step B18) in portion 16.
If the communication number of retries of the signal is less than α ("No" of step B13), process processing unit 14 is retried by communication
The communication that control unit 18 carries out the signal retries, and increases the count value of retryCounter 18a by (step B17).
In addition, in the case where not detecting transmission abnormality by transmission abnormality test section 17, that is to say, that by just
Secondary communication or communication retries successfully by the signal in the case that normally data transmit ("No" of step B10), mistake
The communication number of retries of the signal counted by retryCounter 18a is zeroed (step B14) by journey processing unit 14.
On the other hand, for the signal of different degree 2 ("Yes" of step B15), process processing unit 14 confirmation by
Whether the communication number of retries for the signal that the retryCounter 18a of transmission abnormality test section 17 is counted has reached upper limit value β (step
Rapid B13).In this case, α > β, about the signal of different degree 2, compared with the signal of different degree 3, the limitation retried is set to
By force.In the case where the communication number of retries of the signal has reached upper limit value β ("Yes" of step B13), process processing unit 14 is logical
Cross communication retry control unit 18 retry abnormity detection portion 18b by the signal retry mistake to operation control section 11 notice and
(step B18) is registered to storage unit 16.
If the communication number of retries of the signal is less than β ("No" of step B16), process processing unit 14 is retried by communication
The communication that control unit 18 carries out the signal retries, and increases the count value of retryCounter 18a by (step B17).In addition,
In the case where signal for different degree 1 ("No" of step B15), do not coped with especially transmission abnormality process processing unit 14 and
It is that processing terminate.
Here, when confirm from retry abnormity detection portion 18b be notified of retry mistake when (step B19), be set to elevator
The operation control section 11 of control device 10 carries out following such operating according to the different degree for retrying the signal of mistake is become
Control.
That is, in the case where becoming the signal for retrying mistake and being different degree 3 ("Yes" of step B20), operation control section
The presence or absence of passenger in 11 confirmation cages 20 (step B21).The presence or absence of passenger can be according to being detected by load transducer 7
The loading load of cage 20 is confirmed.
As shown in the transfer management table T1 of Fig. 3, becomes in the signal of different degree 3 and retry mistake, at this time in cage 20
In the case where inside having passenger ("Yes" of step B21), operation control section 11 makes cage 20 stop at nearest floor and opens the door
(step B22).When having confirmed after enabling under passenger ("Yes" of step B23), operation control section 11 is by cage
20 close the door and the operating of elevator are made to stop (step B24).
If there is passenger ("No" of step B23) in cage 20 after enabling, operation control section 11 is standby to multiplying
Until visitor gets off.In addition, whether passenger, which has got off, to judge according to the variation of the loading load of cage 20.?
That is if after the enabling of cage 20, the loading load variations of cage 20 be the initial value (load that passenger is zero
Value), then it can be judged as that the passenger personnel of cage 20 get off.In cage 20 in above-mentioned steps B21
In the case where interior no passenger, operation control section 11 makes the operating of elevator stop (step B24) immediately.
In addition, in the case where becoming the signal for retrying mistake and being different degree 2 ("No" of step B20), if riding
There is passenger ("Yes" of step B25) in carriage 20, then the registration of the car call of the confirmation of operation control section 11 calling registration form 11a
State (step B26).In the case where registering car call ("Yes" of step B26), operation control section 11 makes cage
20 operate to the registration floor (by car call designated destination floor) (step B27) of the car call.Operation control section
11, which are continued until the operating of cage 20, has responded all car calls being registered in calling registration form 11a
Only.
When the not no registration ("No" of step B26) of car call, the passenger for confirming in cage 20 have got off
Cage 20 is closed the door and the operating of elevator is made to stop (step B24) by ("Yes" of step B23), operation control section 11.In addition,
Even if, will not be in the operating for the car call being registered in the case where the signal of different degree 2 is transmission abnormality
There are obstacles.In above-mentioned steps B25 in cage 20 without passenger in the case where, operation control section 11 makes the operating of elevator
Stop immediately (step B24).
After the operating of elevator is stopped, operation control section 11 is standby until by predetermined time tb (step B28).This is
Because waiting slightly if being only to have temporarily become transmission abnormality for some reason and being possible to restore communication.Especially in nothing
Line communicate in the case where sometimes according to wave condition and data transmission become unstable, it is advantageous to standby a period of times.Tb can
To be the time identical with the ta of above-mentioned steps A18, it is also possible to the different time.
When by predetermined time tb ("Yes" of step B28), operation control section 11 is carried out for be confirmed whether can be again
(step B29) is transmitted in the test of the secondary operating for starting elevator.Specifically, from 11 pairs of transmission control unit 12 requirements of operation control section
Test transmission, to the 40 transmission test data of carriage control device 30 and boarding place control device as transmission from device.
By test be transmitted without detect transmission abnormality in the case where ("Yes" of step B30), operation control section 11
The counting zero and storage unit 16 of retryCounter 18a in process processing unit 14 are being retried into mistake via the portion 1I/F 13
After zero (step B31), the operating (step B32) of elevator is started again at.
On the other hand, in the case where detecting transmission abnormality by testing transmission ("No" of step B24), operating control
Portion 11 is standby until by predetermined time tb again.
(c) the case where transmission abnormality has occurred in safety signal
