The utility model is characterized in that a frequency changer and a programmable controller (PLC) are combined organically to be exercised in the control of a moving staircase; the staircase can be switched automatically into three running speeds according to the variance of passenger flow volume; a running speed for maintenance is set. The utility model is composed of two infrared photoelectric detecting elements, two contact stepping cushions, and staircase controlling system software. The utility model can save energy from 40% to 60%. The utility model has the advantages of high intelligent degree, low failure rate, strong versatility, safe operation, long service life, etc. The utility model is a novel and practical innervation type frequency converting staircase.
Description
The utility model relates to a kind of staircase frequency-converting control device.
Public escalator has only a kind of running velocity, and long-time full gear operation is undoubtedly a kind of waste of energy.Developing energy-saving escalator is an important goal of staircase technical development.The electric control system of escalator is fairly simple, mainly contains following two kinds:＜1〉relay control;＜2〉PC control, PC replace relay to improve reliability.Chinese patent by retrieval, there is one piece and is entitled as " elevator PLC/VVVF control setup ", notification number: CN2249230Y, it has adopted in recent years, and it is the frequency converter with vector control function AC voltage adjusting, frequency modulation, speed governing by the Programmable Logic Controller of elevator industry widespread use both at home and abroad (being called for short PLC) and frequency converter (abbreviation VVVF).The PLC/VVVF control setup is used for vertical lift, has advantages such as volume is little, degree of intelligence is high, fault rate is low, energy-conservation.But even to this day, do not apply to as yet in the escalator, the frequency conversion staircase that especially has three kinds of running velocitys does not see that report is arranged.
The purpose of this utility model provides a kind of staircase frequency-converting control device, be that frequency converter and PLC are organically combined in utilization and the staircase control, can be converted into three kinds of running velocitys according to the variation of passenger flow volume automatically, and set insopection traveling speed, thereby save energy consumption greatly.
Concrete technical scheme of the present utility model is: a kind of staircase frequency-converting control device, it comprises a Programmable Logic Controller (1) (being called for short PLC), one group of display system (2), a frequency converter (3) and energy bleeder equipment such as (4), and constitutes the complete staircase PLC/VVVF automatic control device of a cover with the staircase control system software with automatic fault diagnosis processing.It is characterized in that: this device also comprises two infrared ray electrical detecting element (5), (6) and two contact mat (7), (8) that are contained in plate below, forward position of being contained in staircase apron plate place, they make people's source signal pass to (9), (10) and (11), (12) point of PLC respectively, the former transmits people's source signal of forward position plate and step intersection, and the latter transmits people's source signal at place, staircase gangway; Run signal (15) breakdown signal (16) of frequency converter (3) output is input to (13) (14) point of PLC; All the other signals connect one to one, and make staircase have three kinds of running velocitys, that is: full gear operation, unmanned low cruise, zero-speed state, and be provided with insopection traveling speed.Between PLC output signal recited above and frequency converter (3) incoming signal and the corresponding connection mode of all the other signals be:＜I〉positive rotaring signal (17) puts with (19) and is connected;＜II〉reverse signal (18) and (20) point is connected;＜III〉speed signal (21), (23) connect with (22), (24) point and realized changing the different speed of output according to flow of the people;＜IV〉acceleration/accel switching signal (25) and (26) point links to each other, has startup acceleration/accel handoff functionality;＜V〉(27), (29) of frequency converter, triple line (28), (30), (32) that (31) insert electrical motor M respectively, realize control to electrical motor;＜VI〉eight output points of PLC and eight entrance points of display system (2) connect one to one and finish the code display of fault and running state.
The utility model is organically in conjunction with having used frequency converter and PLC control technology, thoroughly changed the single running state of traditional escalator, have according to passenger flow volume variation automatic guidance and be converted to three kinds of running velocitys and insopection traveling speed, give the brand new impression, that this device has more is energy-conservation, degree of intelligence is high, fault rate is low, highly versatile, advantage such as safe and reliable to operation, comfortable, is a kind of novelty, practicality, dynamic formula staircase.
Introduce accompanying drawing of the present utility model below.
Fig. 1 is the utility model schematic diagram;
Fig. 2 staircase PLC/VVVF control flow chart.
Further describe the utility model embodiment and working process below in conjunction with accompanying drawing.
Embodiment: a kind of staircase frequency-converting control device, wherein Programmable Logic Controller (1) is selected the CPM1A series of PLC of Japan for use; Frequency converter (3) is selected a day intrinsic safety river VS-616G5 type for use; Infrared ray electrical detecting element (5), (6) are selected the Japan OMRON product for use; Energy bleeder (4) the unnecessary energy of can releasing when the VVVF voltage overload: display system (2) on control panel, is accomplished directly perceived, in time with code display.According to behind the electrical wiring of the present invention, during start, system parameter is in readiness for action behind initial reset, contact mat (7), (8) pass to PLC after having detected people's signal, after routine processes, judge service direction and give frequency converter (3) control command, frequency converter starts operation, detects unmanned signal after operation a period of time and then is kept to low speed; As detecting unmanned using escalator signal for a long time, then can be kept to zero-speed.And when fault took place, it is out of service that PLC judges, and demonstrate code by display system (2).Thus obtained frequency conversion staircase, having " 1 " full gear running state is 0.5 meter per second; During " 2 " unmanned using escalator, low cruise can be set at 0.2 meter per second: " 3 " inspection travel state is 0.3 meter per second and zero-speed state.Verify repeatedly that through the contriver it is energy-conservation 40%～60% that this device has, and effectively protected electrical motor M; And, greatly facilitate service personnel for repair and maintenance provides demonstration directly perceived, prolonged staircase service life.
