(3) details of elevator controlling power monitoring process
Then, the details of the elevator controlling power monitoring process of present embodiment is described.Fig. 2 is the diagram of circuit of the details representing the process of elevator controlling power monitoring.
As shown in Figure 2, observation circuit is first utilized to monitor power line voltage (S201).Specifically, the first observation circuit 103 monitors that, from the second independent power line voltage controlling power supply 102 and export, the second observation circuit 104 monitors from the first independent power line voltage controlling power supply 101 and export.
Then, the power state signal 110 comprising the result of supervision is outputted to elevator control circuit 106 and elevator power power control circuit 107 by the first observation circuit 103.Further, the power state signal 111 comprising the result of supervision is outputted to elevator control circuit 106 and elevator power power control circuit 107 by the second observation circuit 104.
Then, control microcomputer 105 judges the first independent output voltage whether abnormal (S202) controlling power supply 101.In step S202, it is the situation of exceptional value that the situation of output voltage exception comprises such as output voltage performance, and output voltage exceedes in the permissible range short time situation etc. sharply rising and sharply decline.
In step S202, when being judged as the output voltage exception of the first independent control power supply 101, control microcomputer 105 makes elevator stop (S204).Specifically, control microcomputer 105, when the rising of voltage or lower degradation exception being detected, makes the control break of contact of a side of elevator power power control circuit 107, stops elevator power power supply output 112 and elevator is stopped.
On the other hand, in step S202, not abnormal at the output voltage of the first independent control power supply 101, namely in normal situation, control microcomputer 105 judges the output voltage whether abnormal (S203) of the second independent control power supply 102.
In step S203, when being judged as the second independent control power supply 102 exception, control microcomputer 105 makes elevator stop (S204).Specifically, control microcomputer 105, when the rising of voltage or lower degradation exception being detected, makes the control break of contact of the opposing party of elevator power power control circuit 107, stops elevator power power supply output 113 and elevator is stopped.
On the other hand, in step S204, be not abnormal at the second independent power supply 102 that controls, namely in normal situation, control microcomputer 105 is judged as that power line voltage is normal, returns step S201, continues supervision power line voltage.
Then, control microcomputer 105 judges whether the first independent the abnormal of power supply 101 that control continues (S205).In step S205, when being judged as the aberrant continuation of the first independent control power supply 101, control microcomputer 105 makes the halted state of elevator continue, and makes the time meter counting of elevator inoperative increase (S211).
On the other hand, in step S205, be judged as that the first independent the abnormal of power supply 101 that control does not continue, namely first independent control the normal situation of power supply 101 under, control microcomputer 105 judges whether the second independent the abnormal of power supply 102 that control continues (S206).
In step S206, when being judged as the aberrant continuation of the second independent control power supply 102, control microcomputer 105 makes the halted state of elevator continue, and makes the time meter counting of elevator inoperative increase (S211).
On the other hand, in step S206, be judged as that the second independent the abnormal of power supply 102 that control does not continue, namely in the normal situation of the second independent control power supply 102, control microcomputer 105 makes 2 of elevator power power control circuit 107 to control contact both sides connection, supplies elevator power power supply output 114 and elevator is reset (S207).
Then, after control microcomputer 105 makes elevator reset in step S207, again judge the first independent control power supply 101 whether abnormal (S208).
In step S208, when being judged as the first independent control power supply 101 exception, namely when the first independence controls voltage rise or the decline of power supply 101, control microcomputer 105 makes elevator stop, and makes the time meter counting of elevator inoperative increase (S211).
On the other hand, be judged as that the first independent control power supply 101 is not abnormal in step S208, namely in normal situation, control microcomputer 105 judges the second independent control power supply whether abnormal (S209).
In step S209, when being judged as the second independent control power supply 102 exception, namely when the second independence controls voltage rise or the decline of power supply 102, control microcomputer 105 makes elevator stop, and makes the time meter counting of elevator inoperative increase (S211).
On the other hand, in step S209, be judged as that the second independent power supply 102 that controls not is abnormal, namely in normal situation, control microcomputer 105 makes elevator continuous running until rest in closest to floor, when being accommodated to closest to floor and after confirming that passenger leaves elevator by sensor (not shown) etc., exporting danger signal from elevator control circuit 106 pairs of elevator power power control circuits 107.Then, control microcomputer 105 makes the control break of contact of elevator power power control circuit 107, stops elevator power power supply to export the output of 114, makes elevator stop (shutdown).
In step S211, after control microcomputer 105 makes elevator stop, when elevator does not restore because of abnormity of power supply, be considered as elevator non-operating state, from this time, start time meter count.Then, control microcomputer 105 judges whether gate time continues more than 5 seconds (S212).
In step S212, when being judged as that gate time continue for more than 5 seconds, be judged as elevator cisco unity malfunction, control microcomputer 105 makes elevator stop (S213) (namely, before confirmation safety, make elevator can not be switched to the state automatically run).In step S213, control microcomputer 105, while making elevator stop, also stops the first observation circuit 103 and the second observation circuit 104 to the first independent supervision controlling power supply 101 and the second independent control power supply 102.
On the other hand, when being judged as that in step S212 gate time does not continue more than 5 seconds, control the process of use microcomputer 105 again repeatedly after step S205.That is, keep the state that elevator is stopped, continuing the supervision that first controls the power supply status of power supply 101 and the second control power supply 102.
Like this, in step S204, when again making elevator starter after making elevator temporarily stop because there is abnormity of power supply, there is the first independent power supply 101 or second that controls and independently controlling the possibility that power supply 102 becomes unstable state again.So, after resetting elevator first independent control power supply 101 and second independent control the normal situation of power supply 102 under, elevator is run until closest to floor, after passenger leaves car, makes elevator stop.
Such as, judge can't help control microcomputer 105, when judging operation and the stopping of elevator by means of only time meter, can not learn elevator stops or resetting under what kind of situation, can not guarantee the safe operation of elevator.
But, according to the present embodiment, using 2 observation circuits mutually to monitor power line voltage by independently controlling power supply to 2, can the state of the exception of power supply be controlled according to 2 and correspondingly suitable signal be exported to elevator control circuit 106 and elevator power power control circuit 107.Like this, by not via the hardware circuit of control microcomputer and the signal of these both sides of microcomputer circuit, the electrical source of power of elevator is controlled.
(4) effect of present embodiment
As mentioned above, according to the embodiment of the present invention, by the observation circuit corresponding with independently power supply, the rising of mutual supervision power line voltage or decline, according to the state of this exception and correspondingly to elevator control circuit and elevator power power control circuit output signal, by not controlling the electrical source of power of elevator via the hardware circuit of microcomputer and the signal of these both sides of microcomputer circuit, thus can under the state controlling power good, elevator be run, passenger is provided to the elevator that can more safely use.
