The specific embodiment
Below, with reference to accompanying drawing form of implementation of the present invention is described.
Fig. 1 representes the apparatus for controlling elevator as an embodiment of the present invention.
Be used to keep watch on the speed monitoring control setup of elevator speed, by as the rotary encoder 1 of speed detector (below be called RE1) and the microcomputer 2 (below be called microcomputer 2) that is used for handling the output signal of RE1 constitute.At this, RE1 is installed on the not shown governor (governor), and corresponding to the rotation of governor rope sheave output pulse signal.The speed monitoring control setup carries out the moving velocity that calculation process is obtained lift car through the impulse singla of 2 couples of RE1 of microcomputer, and when this moving velocity reaches the speed of regulation the output speed information signal.In this form of implementation, the velocity information signal refers to that 10% speed detected state signal 5 and moving velocity that moving velocity reaches 10% above time output of rated speed of lift reach the 90% speed detected state signal 6 that 90% of rated speed of lift is exported when above.
Speed detected state signal 5,6 is imported in the microcomputer 4 that elevator control gear uses (below be called microcomputer 4).At this; 4 pairs of microcomputers are installed in that rotary encoder 3 on the motor reel of elevator hoist (below be called RE3) just is installed in the rotation of the rope sheave on the electrical motor corresponding to the rotation of electrical motor and the impulse singla exported carries out calculation process, obtain the speed of lift car.And elevator control gear compares through 4 pairs of these speed of microcomputer and speed detected state signal 5,6, to detect the unusual of RE1 or microcomputer 2.
In addition, elevator control gear carries out drive controlling according to the speed of the lift car that is obtained by microcomputer 4 computings to winch, controls the speed or the position of lift car thus.Lift car is connected with hoist cable with counterbalanced weight, and the hoist cable volume hangs on the rope sheave of winch.When rope sheave rotated under the drive of the electrical motor of winch, hoist cable was driven, thereby lift car and counterbalanced weight are gone up and down in hoist trunk.
The state of each signal when Fig. 2 representes normal operation.Normally the speed of lift car is carried out under the state of arithmetic operation at RE1 and microcomputer 2, the speed through RE3 and microcomputer 4 detected lift cars reach command speed 10% with 90% o'clock, 5,6 connections (ON) of speed detected state signal.
The state of each signal of (speed gain is high) when Fig. 3 representes abnormal operation.Detect in the speed of being carried out and to take place to cause unusually under the situation that speed gain raises because of RE1 and microcomputer 2,90% speed detected state signal 6 the speed signal by RE3 and microcomputer 4 detected lift cars reach command speed 90% before connection (ON).Thus, microcomputer 4 detects speed monitoring control setup unusual of the fault that comprises RE1 and microcomputer 2 etc.
The state of each signal of (speed gain is low) when Fig. 4 representes abnormal operation.Detect in the speed of being carried out because of RE1 and microcomputer 2 and to take place to cause unusually under the situation that speed gain reduces, 10% speed detected state signal 5 is connected (ON) in 10% back that is being reached command speed by RE3 and microcomputer 4 detected speed signals.Thus, microcomputer 4 detects the unusual of speed monitoring control setup.
In addition, though can only detect unusually, in the elevator of some specification, under speed, move sometimes less than command speed through 90% speed detected state signal 6.At this moment and since when normal operation the moving velocity of lift car also the out of reach command speed 90%, so iff detects unusually through 90% speed detected state signal 6, then might detect less than unusually.Thus, unusual in order also to detect when the low speed, so need 10% speed detected state signal 5.
Fig. 5 is illustrated in the state less than each signal under the low cruise state of command speed.When between the floor of close together, moving or when low cruise etc.; All do not reach under the state of command speed at RE1 and both detected speed of RE3; When the speed of being carried out because of RE1 and microcomputer 2 detected and takes place to cause speed gain to occur changing unusually, 10% speed detected state signal 5 in RE1 and the microcomputer 2 was connected time and the RE3 of (ON) and time that microcomputer 4 detected speed signals reach 10% command speed becomes inconsistent.Thus, even under the state less than the low cruise of rated speed of lift, the speed that also can detect RE1 and microcomputer 2 detects unusual.
As described above; Taken place when unusual at the speed monitoring control setup that comprises RE1 and microcomputer 2; Through detecting by RE1 and microcomputer 2 detected speed detected state signals 5 and 6 with RE3 through elevator control gear and microcomputer 4 and the difference in time 7,8 between the detected car speed signal, can detect RE1 and microcomputer 2 fault constant velocity monitor-control apparatus unusually.In addition, detecting when unusual, elevator control gear generates the halt instruction of lift car, and to the elevator management person with transmission anomaly detection signals such as terminal and administrative centers.
According to above-mentioned form of implementation, can come the unusual of detection speed monitor-control apparatus according to the speed state signal (for example 2 bit signals) of speed detected state signal 5 and 6 these two points.And, can reduce or need not be used between speed monitoring control setup and elevator control gear, communicating fully the program of processing.For this reason, the structure of apparatus for controlling elevator becomes fairly simple.So can reduce the parts kind of apparatus for controlling elevator, reduce the cost of apparatus for controlling elevator, and can improve the reliability of trouble detect circuit itself.
