Description
Technical field
Utility model relates to a kind of apparatus for controlling elevator with standby power supply module, belongs to a kind of standby power supply device field with lift facility of motor driver.
Background technology
Usually with motor man lift and cargo lift are driven.Wherein can adopt various lift transfer principles to lift car.The most frequent embodiment is that rotating machine directly or by the transmission device that acts on driving wheel drives ropeway carrying-rope, and the end suspension lift car of described ropeway carrying-rope and the other end hang counterweight and the latter is moved.Rotating machine drives a Hydraulic Pump in another embodiment, and described Hydraulic Pump is mainly controlled one or more hydraulic actuating cylinders by pressure fluid, and described hydraulic actuating cylinder directly or by the cable transmission drives lift car.
According to another driving principle, utilize a linear electric machine that lift car or its connected counterweight of ropeway carrying-rope of passing through are promoted or decline.The adjusting of the speed of lift car changes by adjusting to the frequency that flows to the alternating current that drives alternating current dynamo mostly and realizes in the lift facility in modern times.Usually the common ground of all these actuating devices is to obtain energy by power net, wherein occurs voltage drop or interruption and the power failure for a long time of short time sometimes.These power issues will not bring inconvenience to the passenger in having the lift facility of standby power supply device.In this case, lift car is parked between the anchor point of two floors, this situation: wait upon and cause not having the outer help passenger of elevator can not leave car, for fear of the generation of this type of situation, a part of lift facility is equipped with standby power supply device.Described symbol comprises an energy storage with supply unit, utilizes stored energy to make actuating device lift car can be transported at least next floor and makes the system relevant with elevator keep mode of operation before arriving next floor.
At US 5,058, disclosed a kind of like this standby power supply device in 710, this standby power supply device will be to drive motor and to evacuating other important electric component feed power supply of operation, until next floor of elevator car arrives when occur having a power failure or the alternating-current voltage/AC voltage pressure drop of short time or alternating-current voltage/AC voltage occurring and interrupt at the elevator run duration.When normal operation, the battery (storage battery) as Storage Unit is carried out floating charge with a charger, and its electrode contact by the power monitoring relay when having a power failure is connected with the dc voltage intermediate circuit of the frequency converter of a pair of drive motor feed.
The standby power supply device that has as the electrochemical storage cell of storage battery as independent energy accumulator has following several big shortcoming.During application, to be drive unit for lift utilize when having a power failure energy accumulator is interrupt run and when the fully loaded lift car not being transported to the next floor of service direction at least, energy accumulator must realized bigger discharge power in the relatively short time with not slowing down not.Electrochemical storage cell have less relatively power density (about 300 watts/kilogram) and when being applied to high-performance elevator measuring of its quality will reach the hundreds of kilogram.Often must provide in the equipment of this power at storage battery, the life-span of storage battery will be shortened sharp.Because the charge power that allows then will produce chain problem widely less than horsepower output,, when elevator can be worked again, must wait for that the time of length charges when sending a telegram here again in storage battery.Otherwise will exist lift car when having a power failure once more, to be parked in two risks between the floor.Another shortcoming of using storage battery in lift facility is regularly to monitor and to safeguard and will leave over many deletrious refuses down when reaching its service life to it.
The utility model content
The utility model purpose is to provide a kind of apparatus for controlling elevator with standby power supply module at the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
The utlity model has the apparatus for controlling elevator of standby power supply module, it is characterized in that comprising elevator drive module and standby power supply module, wherein the elevator drive module is composed in series successively by current rectifying and wave filtering circuit, regenerative circuit, inverter, electrical motor and elevator, the input termination external power supply of current rectifying and wave filtering circuit; Power governor, piezoelectric detector, charge capacity infer that circuit, controller, charge-discharge control circuit, charge-discharge circuit are connected in series successively in the standby power supply module, charge-discharge circuit is electrically connected with power governor, power governor is electrically connected with battery pack, the input end of the output termination controller of piezoelectric detector, the mouth of the input termination current rectifying and wave filtering circuit of piezoelectric detector connects, and control circuit is electrically connected with inverter.
Advantage of the present utility model is, only needs a unique power module, and this module preferably has the ability (the single actuating device of employing low power ranges is too expensive usually) that the braking energy of surplus is fed back to electric power network.Second advantage is can directly carry out energy compensating by shared regenerative circuit.In addition, only need a unique standby power supply device of the present utility model to replace a plurality of independent standby power supply devices, thereby can significantly reduce spending of hardware and decrease cost.
