The specific embodiment
Further describe the present invention below in conjunction with accompanying drawing.
Work of the present invention is finished by uplink and downlink signals collection, speed signal collection, band-type brake control, speed governing and energy-saving run, band-type brake monitoring (selecting for use), ladder speed monitoring (selecting for use), several links; Concrete principle of work is as follows:
Up-downgoing operation (Fig. 1): operating personal as prescribed starting staircase, the former control setup of staircase detects on the connection terminal that provides three plase alternating current A, B, the C staircase motor in the circuit of the present invention after each safety switch satisfies the requirements automatically, with input terminal R/L1, the S/L2 of frequency converter, T/L3 continuous cropping converter power supply mutually.Be connected on up relay SXJ, descending relay XXJ and other element by K switch 1 on the other hand.When three-phase electricity that provides when former control housing and up phase sequence relay SXJ phase sequence match, up phase sequence relay SXJ action, by open contact up contactless switch SXC coil is got, F7 is in normal condition as frequency converter, the malfunctioning node MC of frequency converter and MB conducting, the open contact of up contactless switch SXC makes the upstream node S1 and the speed uplink node S5 conducting simultaneously of frequency converter, and escalator is up.When three-phase electricity that provides when former control housing and descending phase sequence relay XXJ phase sequence match, descending phase sequence relay XXJ action, by open contact descending contactless switch XXC coil is got, F7 is in normal condition as frequency converter, the malfunctioning node MC of frequency converter and MB conducting, the open contact of descending contactless switch XXC makes the descendant node S2 and the downstream rate node S6 conducting simultaneously of frequency converter, and escalator is descending.
Band-type brake control (Fig. 3): the three-phase electricity that provides when former control housing arrives the present invention simultaneously, and the present invention is connected on the contact conducting in the former control circuit band-type brake wire loop.That up contactless switch SXC or descending contactless switch XXC get is electric, operation contactless switch YXC get electric, the open contact conducting of up contactless switch SXC or descending contactless switch XXC, the energising of band-type brake line bag, band-type brake open.Former control housing disconnects apparatus of the present invention power supply, the outage of staircase motor when pressing stop button, and staircase is out of service, is connected on contact open band-type brake, band-type brake closure in the former control circuit band-type brake wire loop simultaneously.
Speed governing and energy-saving run (Fig. 2): when frequency converter F7 receives upward signal S1 (or downgoing signal S2), frequency converter run signal M1, M2 conducting, operation contactless switch YXC get, the contact of up contactless switch SXJ (or descending contactless switch XXJ) disconnects frequency converter extrinsic base blocking instruction, speed signal S5 (or S6) and S7 are in conducting state at this moment, frequency converter is given the staircase electrical power through U/T1, V/T2, W/T3, and staircase starts normal upstream or downstream; Do not have the passenger as the entrance and enter about 18 seconds, the normally closed contact of time relay DH48S starting, time meter DH48S disconnects frequency converter high speed signal S7, and staircase reduces to low cruise.When the entrance has the passenger to enter photoelectric switch receiving device GDF or GDF1 get electric, make through the contact of up contactless switch SXC or descending contactless switch XXC and to detect relay GDJ and get, the contact of detecting relay GDJ resets time relay DH48S, and the contact of time relay DH48S makes frequency converter high speed signal S7 conducting, staircase accelerate to the normal speed operation.
