Emergency braking device 33, control panel 102, towing machine brake equipment 106, detecting device 112 and storage part 113 are electrically connected with efferent 114 respectively.In addition, along with effluxion, respectively to efferent 114 continuously input from the position detection signal of car position sensor 109, from the speed detection signal of car speed sensor 110, from the acceleration detection signal of car acceleration pick-up 111.Efferent 114 is according to the input of position detection signal, calculate the position of car 3, according to speed detection signal and the input separately of acceleration detection signal, calculate the speed of car 3 and the acceleration/accel of car 3 respectively in addition, judge key element unusually as multiple (in the present embodiment being two kinds).

When the speed of car 3 surpasses the 1st abnormal speed test pattern 116, or when the acceleration/accel of car 3 during above the 1st unusual acceleration detection figure 119, efferent 114 is to towing machine brake equipment 106 output action signals (energizing signal).In addition, efferent 114 is in towing machine brake equipment 106 output action signals, is used to stop the danger signal of the driving of towing machine 101 to control panel 102 outputs.And when the speed of car 3 surpasses the 2nd abnormal speed test pattern 117, or when the acceleration/accel of car 3 during above the 2nd unusual acceleration detection figure 120, efferent 114 is to towing machine brake equipment 106 and emergency braking device 33 output action signals.That is, efferent 114 is determined the brake equipment of output action signal according to the speed of car 3 and the intensity of anomaly of acceleration/accel.

Other formation is the same with embodiment 2.

Below, action is described.If will be from the position detection signal of car position sensor 109, from the speed detection signal of car speed sensor 110, be transfused to efferent 114 from the acceleration detection signal of car acceleration pick-up 111, then efferent 114 is calculated position, speed and the acceleration/accel of car 3 according to the input of each detection signal.Afterwards, the speed and the acceleration/accel of the car 3 that unusual judgment standard of car speed that efferent 114 is obtained from storage part 113 more respectively and the unusual judgment standard of car acceleration/accel, comparison are calculated according to the input of each detection signal, the speed and the acceleration/accel that detect car 3 each have no abnormal.

When normal operation, the speed of car 3 is the value roughly the same with the normal speed test pattern, the acceleration/accel of car 3 is the value roughly the same with the normal acceleration test pattern, so the speed and the acceleration/accel of efferent 114 detection cars 3 are no abnormal separately, continues the normal operation of elevator.

For example, when the velocity anomaly of car 3 for a certain reason rises and surpasses the 1st abnormal speed test pattern 116, the speed that efferent 114 detects car 3 has unusually, respectively to towing machine brake equipment 106 output action signals, exports danger signals to control panel 102 from efferent 114.Thus, when stopping towing machine 101,106 actions of towing machine brake equipment are braked the rotation that drives rope sheave 104.

In addition, in the acceleration/accel abnormal ascending of car 3 and above under the situation of the 1st unusual acceleration/accel setting value 119,, respectively to towing machine brake equipment 106 and control panel 102 output action signal and danger signals the rotation that drives rope sheave 104 is braked from efferent 114.

After 106 actions of towing machine brake equipment, in the further rising of the speed of car 3 and above under the situation of the 2nd abnormal speed setting value 117, keep to towing machine brake equipment 106 output action signals constant, from efferent 114 to emergency braking device 33 output action signals.Thus, emergency braking device 33 action is braked car 3 by the action the same with embodiment 2.

In addition, after 106 actions of towing machine brake equipment, in the further rising of the acceleration/accel of car 3 and above under the situation of the 2nd unusual acceleration/accel setting value 120, keep to towing machine brake equipment 106 output action signals constant, to emergency braking device 33 output action signals, emergency braking device 33 moves from efferent 114.

In this lift appliance, monitor unit 108 is according to the information from detection elevator status detection device 112, obtain the speed of car 3 and the acceleration/accel of car 3, and one of in the acceleration/accel of the speed of the car 3 that judgement obtains and car 3 when unusual, to towing machine brake equipment 106 and emergency braking device 33 at least one output action signal, so can more early detect the unusual of elevator by monitor unit 108 more reliably, further shorten producing the time required to the braking force of car 3 from abnormal elevator.Promptly, have no abnormal because monitor unit 108 is judged the speed of car 3 and the multiple unusual judgement key elements such as acceleration/accel of car 3 respectively separately, so can more early detect the unusual of elevator by monitor unit 108 more reliably, can shorten from abnormal elevator producing the required time to the braking force that produces car 3.

In addition, because the acceleration/accel that monitor unit 108 has speed that storage is used to judge car 3 to be had the unusual judgment standard of N/R car speed and be used to judge car 3 has the storage part 113 of the unusual judgment standard of N/R car acceleration/accel, each have N/R judgment standard so can easily change the speed and the acceleration/accel of car 3, also design modification of corresponding elevator etc. easily.

In addition, in the unusual judgment standard of car speed, set normal speed test pattern 115, the 1st abnormal speed test pattern 116 that value is bigger than normal speed test pattern 115, the 2nd abnormal speed test pattern 117 bigger than the 1st abnormal speed test pattern 116 with value, when the speed of car 3 surpasses the 1st abnormal speed test pattern 116, from monitor unit 108 to towing machine brake equipment 106 output action signals, when the speed of car 3 surpasses the 2nd abnormal speed test pattern 117, from monitor unit 108 to towing machine brake equipment 106 and emergency braking device 33 output action signals, so can brake car 3 by stages corresponding to the velocity anomaly size of car 3.Therefore, can car 3 be stopped reducing when car 3 applies the frequency of big impact.

In addition, in the unusual judgment standard of car acceleration/accel, set normal acceleration test pattern 118, the 1st unusual acceleration detection figure 119 that value is bigger than normal acceleration test pattern 118, the 2nd abnormal speed test pattern 120 bigger than the 1st unusual acceleration detection figure 119 with value, when the acceleration/accel of car 3 surpasses the 1st unusual acceleration detection figure 119, from monitor unit 108 to towing machine brake equipment 106 output action signals, when the acceleration/accel of car 3 surpasses the 2nd unusual acceleration detection figure 120, from monitor unit 108 to towing machine brake equipment 106 and emergency braking device 33 output action signals, so can be according to the unusual big or small car 3 of braking by stages of the acceleration/accel of car 3.Usually, because produce unusually, so can car 3 be stopped further reducing when car 3 applies the frequency of big impact at the acceleration/accel of the unusual preceding car 3 of the speed generation of car 3.

In addition, because set normal speed test pattern the 115, the 1st abnormal speed test pattern 116 and the 2nd abnormal speed test pattern 117, so can on whole positions in the lifting zone of car 3, make the 1st abnormal speed test pattern 116 and the 2nd abnormal speed test pattern 117 correspond respectively to normal speed test pattern 115 according to the position of car 3.Therefore because especially in the acceleration and deceleration interval value of normal speed test pattern 115 little, so the 1st abnormal speed test pattern 116 and the 2nd abnormal speed test pattern 117 can be set at less value respectively, can reduce to brake the impact that car 3 is produced.

In addition, in the above-described embodiments, monitor unit 108 uses car speed sensor 110 for the speed that obtains car 3, but also can not use car speed sensor 110, and according to the speed that derives car 3 by the position of car position sensor 109 detected cars 3.That is, can differentiate, calculate the speed of car 3 by position to the car 3 of calculating from the position detection signal of car position sensor 109.

In addition, in the above-described embodiments, monitor unit 108 uses car acceleration pick-up 111 for the acceleration/accel of obtaining car 3, but also can not use car acceleration pick-up 111, and according to the acceleration/accel of deriving car 3 by the position of car position sensor 109 detected cars 3.That is, can ask second differential, obtain the acceleration/accel of car 3 by position to the car 3 of calculating from the position detection signal of car position sensor 109.

In addition, in the above-described embodiments, efferent 114 is determined the brake equipment of output action signal according to the speed of the car 3 of judging key element unusually and the intensity of anomaly of acceleration/accel as each, but also can determine the brake equipment of output action signal to each unusual judgement key element in advance.
