The specific embodiment
Below in conjunction with accompanying drawing technical solution of the present invention is elaborated.
As shown in Figure 1, the invention provides a kind of staircase integral frequency conversion controller 1, mainly comprise: controller circuitry 11, motor-drive circuit 12 and power circuit 13 based on the bypass converter technique.The power supply of control circuit 11 is introduced from the outside, motor-drive circuit 12 is controlled arm rest lift traction machine to external output signal, the outward sign 5 that control circuit 11 is accepted from frequency-variable controller " peripheral hardware ", the signal output after control circuit 11 is handled is given motor-drive circuit 12.The integrated frequency conversion control circuit of staircase is gathered various on-off signals, thus the drive motor operation, and whether the running state that is constantly detecting staircase simultaneously is normal, in case unusual, then can stop immediately, to guarantee passenger's safety.And the parameter setting is relatively simple, before staircase uses, carry out parameter of electric machine setting, for the normal operation of staircase provides foundation.
Control part is the technology of the present invention key, its agent structure block diagram comprises as shown in Figure 2: modules such as motor status detection module, motor-driven algoritic module, PWM module (pulse width modulation module), parameter storage control module, curve calculation and control module, clock module, staircase control logic module, terminal input and output.
Fig. 3 is a kind of control-driven system block diagram of using based on the staircase integral frequency conversion controller typical case of bypass converter technique, mainly comprises: staircase integrated controller 1, the synchronous switch card 2 of power supply and alternating current dynamo 3.R, S, T represent three phase lines of industrial power among the figure, and U, V, W represent three phase lines of frequency converter out-put supply, and Kup, Kdown are up, the descending contactless switchs of control staircase, and Kout is the contactless switch that adopts frequency conversion drive to use.In the up process of staircase, Kout is closed earlier, and staircase adopts frequency conversion drive to quicken, and after accelerating to the staircase command speed, Kout disconnects, the Kup closure, and staircase moves under the driving of electric network source then, and the staircase service direction is upwards; After staircase did not have the passenger and enters a period of time, Kup disconnected, Kout closure, the staircase standby of slowing down under the driving of frequency conversion; Staircase is descending identical with the upload control sequential.
As can be seen from Figure 3, staircase mode of the present invention is a kind of bypass frequency conversion drive, and converter plant is set on staircase, adopts variable frequency starting when staircase brings into operation, when staircase reached the command speed stable speed operation, staircase switched to the industrial frequency operation by synchronous switch card 2 automatic smoothings of power supply.As there is not passenger's using escalator, staircase will switch to converting operation by power frequency operation, by the crawl speed that 100% command speed drops to setting automatically creep (move still unmanned using escalator of a very long time as staircase under 20% speed, then staircase can gently stop ladder automatically and awaits orders, and this function can set up on their own).When the sensor that is installed in staircase gangway place to passenger's using escalator is arranged, then staircase speed horse back gently rises to 100% command speed, switches to the power frequency smooth running once more, continues to enter staircase as the passenger, staircase will normally move with command speed always.Do not detected the passenger again as the sensor of staircase entrance in the predefined time and entered staircase, then staircase will go to the creeper speed operation automatically.
Wherein, the synchronous switch card 2 of power supply is the small difference on the frequencies that utilize two power supplys, samples the synchronizing signal of source of AC, based on this synchronizing signal, the realization variable-frequency power sources takes over seamlessly to industrial power, guarantees staircase seamlessly transitting when converting operation switches to power frequency operation.For improving the ratio of performance to price of equipment, the staircase integral frequency conversion controller can reduce by one grade of power and dispose according to the power of alternating current dynamo 3, such as, if motor rated power is 8kw, then configurable power is the frequency converter of 5.5kw.
