Abstract
The utility model relates to the technical field of elevators, in particular to a device for detecting the running direction of a power-off emergency leveling of an elevator. The device comprises a frequency converter, an electrically-erasable programmable read-only memory (EEPROM), and a sine-cosine encoder, wherein the frequency converter can automatically perform ascending compensation or descending compensation on a moment direction of the elevator when the elevator is started every time; the EEPROM is used for storing ascending compensation information or descending compensation information every time the elevator is started; the sine-cosine encoder inputs a sine or cosine signal to the frequency convertor and is arranged on an elevator main machine shaft; the frequency convertor is provided with a PG card which converts the signal of the sine-cosine encoder, isolates the converted signal and outputs a control signal; the sine-cosine encoder is electrically connected with the frequency convertor which is electrically connected with the EEPROM; and the technical scheme is simple and effective, and cost of the elevator can be reduced greatly.
Description
Technical field:
The utility model relates to the elevator technology field, relates in particular to a kind of elevator current failure emergency flat bed operating direction detecting device.
Background technology:
Elevator be a kind of be the vertical conveyor of power with the electrical motor, case shape gondola is housed, be used for tier building and take advantage of people or carrying goods.Elevator is as the transport facility of vertical direction, become important Architectural Equipment in skyscraper and public place and indispensable.The development of Along with computer technology, automatic technology and Power Electronic Technique, modem elevator have become the representative type electromechanical integrated product.
Traditional elevator; When running into electric power system fault (power failure, phase shortage, fire) suddenly at the elevator that carries out; Its current failure emergency leveling device is devoted oneself to work automatic switchover, takes over the whole controls of elevator, the required electric energy of output elevator; Elevator is moved to level position, open gate and walk out elevator by passenger safety.Existing current failure emergency leveling device, in order to save electric power and cost, often outage back control elevator is toward underloading direction low cruise.At present, the general employing through the weigh mode of control load appearance of setting comes (through output signal semi-load) to judge underloading direction, and this technology is comparatively complicated, has increased the cost of elevator greatly.
The utility model content:
The purpose of the utility model is to the deficiency of prior art a kind of elevator current failure emergency flat bed operating direction detecting device to be provided, and technical scheme is simply effective, can reduce the cost of elevator greatly.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of elevator current failure emergency flat bed operating direction detecting device; It comprises the frequency converter that can carry out up compensation or descending compensation when elevator starts at every turn to the moment direction of elevator automatically; When being used to store elevator and starting at every turn is the EEPROM of up compensation or descending compensated information; And the sine and cosine encoder of input sine or cosine signal to frequency converter, sine and cosine encoder is installed on the elevator main axle; Said frequency converter is provided with the PG card of the signal of sine and cosine encoder being changed, isolated and exports control signal, and said sine and cosine encoder is electrically connected said frequency converter, and said frequency converter is electrically connected said EEPROM.
The utility model beneficial effect is:
The said a kind of elevator current failure emergency flat bed operating direction detecting device of the utility model; Adopting sine and cosine encoder to realize not having weighs when starting; Each direction that starts the record torque compensation when have a power failure next time, is promptly known the direction of elevator underloading; Technical scheme is simply effective, can reduce the cost of elevator greatly.
Description of drawings:
Fig. 1 is the functional block diagram of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Embodiment one
As shown in Figure 1; A kind of elevator current failure emergency flat bed operating direction detecting device; It comprises the frequency converter 3 that can carry out up compensation or descending compensation when elevator starts at every turn to the moment direction of elevator automatically; When being used to store elevator and starting at every turn is the EEPROM4 of up compensation or descending compensated information, and the sine and cosine encoder 1 of input sine or cosine signal to frequency converter 3, and sine and cosine encoder 1 is installed on the elevator main axle; Said frequency converter 3 is provided with the PG card 2 of the signal of sine and cosine encoder 1 being changed, isolated and exports control signal, and said sine and cosine encoder 1 is electrically connected said frequency converter 3, and said frequency converter 3 is electrically connected said EEPROM4.Wherein, preferred, sine and cosine encoder 1 adopts ERN1387 sine and cosine encoder 1, and its resolution is 2048rpm.
Above-mentioned a kind of elevator current failure emergency flat bed operating direction detecting device, its method of inspection be, after device received the sine or cosine signal of the one-period that sine and cosine encoder 1 sends frequently, PG card 2 was decomposed into 128 signals with each periodic signal again; When elevator started at every turn, frequency converter 3 can carry out up compensation or descending compensation automatically to the moment direction of elevator, promptly carries out torque compensation up or down, prevented that elevator from falling to slip; When elevator was up compensation when if elevator started at every turn, a certain position of EEPROM4 is 1; If when elevator was descending compensation when elevator started, this position of EEPROM4 was 0 at every turn; After outage next time, judge the direction of elevator underloading automatically, if frequency converter 3 carries out up compensation automatically before the outage, the weight ratio that car this moment is described is to heavy and light, then outage back emergency flat layer is upwards operation; If frequency converter 3 carries out descending compensation automatically before the outage, the weight ratio that car this moment is described is to heavy, and then outage back emergency flat layer is operation downwards.The said a kind of elevator current failure emergency flat bed operating direction detecting device of the utility model; Adopting sine and cosine encoder 1 to realize not having weighs when starting; Each direction that starts the record torque compensation when have a power failure next time, is promptly known the direction of elevator underloading; Technical scheme is simply effective, can reduce the cost of elevator greatly.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
