In Fig. 1; Group management control apparatus 1 is the group management control apparatus with allocation of elevators control system 4; When any in being arranged on each elevator lobby call button 2 of stopping floor carried out pressing operation, this allocation of elevators control system 4 was distributed the car 3 of the certain elevator in the elevator under its management with the mode that can improve efficiency of service.Group management control apparatus 1 is connected with each elevator control gear 5.The winch 6 of each elevator carries out variable-ratio control by the three plase alternating current of the variable ratio frequency changer transformation that control device of electric motor 7 is supplied with.Group management control apparatus 1 has when each elevator control gear 5 receives abnormal signal the function of arbitrary elevator being moved restriction.
In Fig. 2; Convertor device 10 will be transformed to the direct supply with any power from the three-phase alternating-current supply that source power supply 11 is supplied with; DC-to-AC converter 12 is to be connected with convertor device 10, and direct supply is transformed to the device of the three-phase alternating-current supply of variable ratio frequency changer transformation arbitrarily.The driving control device 9 of pwm converter and inverter is the signal that receives from coder that detects motor speed and position etc. 13 and current probe 14; According to calculating torque instruction value with the speed feedback value that coder 13 obtains, electric winch 15 is carried out the driving control device (controlled reset of electrical motor then state part describe) of speed feedback control with reference to Fig. 4 from the load sensor 17 that is arranged on the lift car 16.
The driving control device 9 of pwm converter and inverter has the live load rate that obtains according to the torque instruction value that sends to electrical motor 8, from load sensor 17 and the residual life of the speed feedback value horsepower rating semiconductor element that obtains from coder 13, and output and show the function of the ageing state of residual life.
Followingly the basic control mode of the related elevator control gear 5 of embodiment of the present invention is described with reference to Fig. 4 and Fig. 5.Fig. 4 is that the load of the related elevator control gear of this embodiment of expression is the parent map of the control system of lift car drive motor, and Fig. 5 is that the speed value and the elevator up-down that are illustrated in the lift car of controlling in the related elevator control gear of this embodiment are sailed the figure that concerns between the number of floor levels.
As shown in Figure 4, be used to drive lift car 3 so that the control system of the electrical motor 8 of its winch that moves up and down 6 according to speed value V
0And calculating current instruction value from the difference (comprising COEFFICIENT K) between the speed feedback value V of the coder 13 of electrical motor 8 is torque instruction value i
0At this, speed value V
0As shown in Figure 5, under the state that goes with constant speed, the number of floor levels that passes through when going up and down according to lift car determines in advance, wherein V
02The expression maxim, V
01The expression minimum value.
As shown in Figure 4, the current instruction value that calculates (torque instruction value) i
0And be input to electrical motor 8 from the deviation between the current feedback value i of current probe 14 via convertor device 10 and DC-to-AC converter 12, make electrical motor 8 produce motor torque, carry out the speed control of elevator thus.
Followingly the action of the related apparatus for controlling elevator of embodiment of the present invention is summarized with reference to Fig. 2 and Fig. 3.The aging frequency of various power semiconductors 18 that constitutes changer shown in Figure 2 and inverter is by the loading condition decision of the drive condition and the electrical motor 8 of convertor device 10 and DC-to-AC converter 12, and can't be merely calculates service life according to the number of starts and the time of run of electrical motor 8.The equipment that live load is not fixed and started repeatedly and stop continually as elevator, the aging frequency of every elevator certainly can be different.
Followingly describe to the method for calculating in the service life of power semiconductor 18 and to the output action (output signal of having exported when the aging frequency of power semiconductor has surpassed threshold value) of exterior group management control apparatus 1 with reference to Fig. 3.
The component life method of calculating of the power semiconductor 18 in the convertor device 10 at first is described.The number of times that the live load rate that is obtained by load sensor 17 and the speed feedback value that is obtained by coder 13 has all been surpassed the threshold value that meeting separately exerts an influence to life-span of power semiconductor 18 is counted; For example; To live load below 25% or more than 75% and the speed feedback value number of times more than 80% that reaches command speed count, and behind integrating, it is stored in the memory device.When this count value has surpassed the threshold value that predefined meeting exerts an influence to life-span of power semiconductor 18 (for example 70% of the life-span count value, 80%, 90%), separately ageing state signal C is sent in the exterior group management control apparatus 1.
The component life method of calculating of the power semiconductor 18 in the DC-to-AC converter 12 below is described.To according to the speed value of lift car 3 and the torque instruction value i that calculates by the speed feedback value that coder 13 obtains
0The number of times that has surpassed the threshold value that can exert an influence to the life-span of power semiconductor 18 (for example more than 75% of rated value, more than 90%) is counted, and behind integrating, it is stored in the memory device.When this count value has surpassed pre-set threshold (for example 70% of the life-span count value, 80%, 90%), separately ageing state signal I is sent in the exterior group management control apparatus 1.
Below to receiving ageing state signal C, the countermeasure of the group management control apparatus 1 behind the I describes.In elevator with the group management control apparatus 1 that efficiently many elevators is moved control; Receiving ageing state signal C; During I, can limit each elevator according to the urgency level of this signal the operation of calling out is distributed, thereby can relax aging process.In addition; Do not have at ageing state under the situation of improved state continuance ground existence; Alteration command that can be through acceleration-deceleration or implement to load restriction (for example carrying capacity being restricted to 35%～65%) with respect to the operation of elevator and wait and reduce the torque of going can relax the ager process of power semiconductor thus.
When group management control apparatus 1 is implemented the countermeasure of the change of above-mentioned acceleration-deceleration and the restriction of live load (suppressing the measure of the ager process of power semiconductor) etc.; Might not be prerequisite with many elevators, these countermeasures also go for being arranged on the occasion that elevator in the building is independent elevator.In above-mentioned occasion, can certainly not implement above-mentioned countermeasure, and implement above-mentioned countermeasure through elevator control gear 5 through group management control apparatus 1.In addition; Being used for making wear out between each elevator of many elevators decentralized countermeasure of life-span is to be provided with many elevators with allocation of elevators and the operation prerequisite of relevant countermeasure such as stop promptly, and above-mentioned countermeasure can be implemented by the group management control apparatus that these elevator group are managed.
In above explanation; Implement to move the field of restriction and be combined into example and be illustrated to manage control through the crowd; And in the elevator control gear of the independent setting of not carrying out crowd management control, then can the ageing state signal be sent to monitor or the remote monitroing center that is arranged in the caretaker room etc.Thus, can predict, can guarantee to purchase the required time of parts, can in time arrange the maintainer, can make contributions for the efficient that improves maintenance and maintenance to the replacing of power semiconductor.
