Abstract
The utility model relates to an elevator driving controller with an emergency floor reaching function, which comprises an elevator program board circuit, a two-way frequency changer with input interfaces of AC and DC electric power supplies, a battery, a power supply detector and an interface circuit, wherein an output end of the elevator program board circuit is connected with an input end of the two-way frequency changer; the other two input ends of the two-way frequency changer are respectively connected with an output end of the power supply detector and the battery; an output end of the two-way frequency changer is connected with an input end of the interface circuit; an output end of the interface circuit is connected with an input end of the power supply detector; the other output end of the power supply detector is connected with an input end of the elevator program board circuit. When an electric net works normally, an elevator works with power supply from the AC power supply; when the electric net has something wrong, the power supply is changed into the DC power supply, which causes an elevator cage lifts slowly to a nearby floor to let passengers leave the elevator safely. The controller integrates the emergency processing function and the normal running, not only can run safely, but also can reduce cost greatly.
Description
Technical field
The utility model relates to a kind of elevator drive controller, especially has the elevator drive controller of emergency story-leveling function.
Background technology
The elevator drive controller has extensively adopted variable-frequency control technique or servo-drive technology.Present elevator drive controller mainly comprises: elevator program board circuit, single channel frequency converter and interface circuit generally all do not have emergency story-leveling function, if customer requirement has this function, need to increase in addition the independent emergency flat layer device of a cover.When the elevator in operation ran into electric power system (power failure, phase shortage, fire) suddenly, " elevator emergency leveling device " automaticallyed switch and devotes oneself to work.At first take over whole controls of elevator, whether each loop of procuratorial work elevator is normal, judges the lift car position, and this device output electric energy drives the traction motor of elevator then, and car is moved to floor nearby at a slow speed, opens gate, allows passenger safety leave elevator.Independent " elevator emergency leveling device " is independent of outside the former elevator drive controller.Therefore disposing independent elevator emergency leveling device need increase extra higher cost, and often the price of this device reaches about 1/2 price of original entire controller.
Summary of the invention
The purpose of this utility model provides a kind of elevator drive controller with emergency story-leveling function, to increase the safety and the emergency handling function of elevator operation.
Elevator drive controller with emergency story-leveling function of the present utility model, comprise elevator program board circuit, the two-way converter plant that contains AC and DC electric supply input interface, battery, Power supply detector and interface circuit, the mouth of elevator program board circuit links to each other with an input end of two-way converter plant, two input ends in addition of two-way converter plant link to each other with battery with a mouth of Power supply detector respectively, the mouth of two-way converter plant links to each other with the input end of interface circuit, the mouth of interface circuit links to each other with the input end of Power supply detector, and another mouth of Power supply detector links to each other with the input end of elevator program board circuit.
The utility model has adopted Power supply detector and two-way converter plant, at mains supply just often, elevator is by power supply the carrying out work of grid alternating current source, when electrical network breaks down, Power supply detector detects breakdown signal, the two-way converter plant changes dc-battery power supply into, the pulse duration modulation of output low frequency low pressure (PWM) drive waveform traction motor, make elevator at a slow speed lifting in rational position.The utility model collection emergency handling function and normally run on one, not only safe and reliable to operation, and cost-cutting significantly.
Description of drawings
Fig. 1 is that the utility model constitutes block diagram;
Fig. 2 is a kind of concrete enforcement circuit diagram of the utility model.
Specific implementation method
With reference to Fig. 1, elevator drive controller with emergency story-leveling function comprises elevator program board circuit 1, the two-way converter plant 2 that contains AC and DC electric supply input interface, battery 3, Power supply detector 4 and interface circuit 5, the mouth of elevator program board circuit 1 links to each other with an input end of two-way converter plant 2, two input ends in addition of two-way converter plant 2 link to each other with battery 3 with a mouth of Power supply detector 4 respectively, the mouth of two-way converter plant 2 links to each other with the input end of interface circuit 5, the mouth of interface circuit 5 links to each other with the input end of Power supply detector 4, and another mouth of Power supply detector 4 links to each other with the input end of elevator program board circuit 1.
Fig. 2 is a kind of concrete enforcement circuit diagram with elevator drive controller of emergency story-leveling function.In the diagram instantiation, what Power supply detector 4 adopted is the HL-1 electric power monitor that Hangzhou Hui Ling company produces; What two-way converter plant 2 adopted is the ES Series Frequency Converter that Britain CT company produces; Interface circuit 5 is made up of air switch QF1, QF2 and contactless switch KM2.The aanalogvoltage mouth VN of elevator program board circuit 1, VZ respectively with the A2 of ES frequency converter, the A1 end links to each other, the I01 of elevator program board circuit 1, the I01 of I02 terminal and ES frequency converter, the I02 terminal is corresponding to link to each other, the I3 of elevator program board circuit 1, the I4 terminal respectively with 01 of HL-1 electric power monitor, 02 terminal links to each other, 03 of HL-1 electric power monitor, 04 terminal respectively with the I03 of ES frequency converter, the I04 terminal links to each other, the dc supply input of ES frequency converter links to each other with battery 3 through contactless switch KM1, battery can adopt the maintenance-free battery of 48V voltage, the U of ES frequency converter, V, the W terminal links to each other with the contactless switch KM2 that is connected the elevator traction motor M, the R of air switch QF1 and HL-1 electric power monitor, S, the T terminal links to each other, the L1 of air switch QF2 and ES frequency converter, L2, the L3 terminal links to each other.Usually, be to solve the interference problem of electromagnetic compatibility, can be as shown in the figure, access electromagnetic compatibility filter between L1, the L2 of air switch QF2 and ES frequency converter, L3 terminal.
When mains supply just often, to the ES inverter supply, the ES frequency converter drives traction motor by U, V, W terminal output electric energy to electrical network through air switch QF2, thereby under the control of elevator program board circuit, makes elevator high and low's operation normally.Wherein the VN of elevator program board circuit, VZ output aanalogvoltage is controlled the output frequency of ES frequency converter; I01, I02 terminal are exported the startup of switching value signal control ES frequency converter and are stopped.When electric power system breaks down, at first detected by Power supply detector, at this moment the KM1 contactless switch closes, battery begins the ES frequency converter is powered, the electric energy of ES frequency converter output low frequency low pressure drives the traction motor of elevator, car is moved to floor nearby at a slow speed, open gate, allow passenger safety leave elevator.
