Description

A kind of automatic energy saving staircase control system

Technical field

This utility model is related to staircase technical field, more particularly, to a kind of automatic energy saving staircase control system.

Background technology

Escalator is more in the application of the places such as hotel, market, subway, railway station, office building, airport, is making things convenient for customers Aspect serves considerable effect with improving service quality etc..But the particularity due to its use occasion, part staircase warp Often it is in the state of underloading or zero load, this will waste substantial amounts of electric energy, will also result in the abrasion of staircase simultaneously.

By current relevant technical standard, the degree of being busy with one's work of escalator can be divided into plain edition and public traffic type Two kinds.The up escalator of outbound that the modal public traffic type escalator of most typically is disposed in subway station.We Carry out field test result to this staircase to show, after arrival of subway, when the artificial abortion that swarms is lasting on the escalator Between be about 45 seconds about, if calculated by every 3 minutes one class of subway, " cyclic duration factor " of staircase is also only 25% about, Remaining time staircase is all to run under unloaded or very low load.Public traffic type escalator is even such, and remaining is common The situation of type escalator is just let alone.Therefore, conservation measures is taken to be very important escalator.

A kind of above-mentioned automatic energy saving staircase control system it is characterised in that：Described converter detection module, converter control Molding block is all from SAMCO-i high function squelch type I-IF type converter.

The beneficial effects of the utility model are：

（1）It is ensured that staircase automatic steady is transitioned into energy-saving run during unmanned boarding, run with relatively low normal speed, section The about energy.

（2）It is ensured that staircase is run it is ensured that normal automatically with energy-saving speed smooth transition to normal speed during someone's boarding Use.

（3）Because during unmanned boarding, energy-saving speed, very slowly so that the abrasion of mechanical part substantially reduces, relatively extends and helps The service life of ladder.

（4）Technology maturation, convenient to carry out and popularization；Using converter multiple functional, simple to operate.And this device volume Less, it is easily installed, can directly be installed in the upper lower platform of staircase.

（5）The employing of converter technique, is greatly reduced the impact to electrical network when staircase starts, can effectively be changed using converter The power factor of kind electrical network, reduces reactive loss.

Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is made furtherly Bright, to be fully understood from the purpose of this utility model, feature and effect.

Brief description

Fig. 1 is overall structure block diagram of the present utility model.

Fig. 2 is the schematic diagram of power save mode of the present utility model.

Specific embodiment

As shown in figure 1, a kind of automatic energy saving staircase control system it is characterised in that：Including PLC master controller 1, switch inspection Survey module 2, converter detection module 3, sensor input module 4, frequency transformer control module 5 and power monitor module 6, described PLC master controller 1 and switch detection module 2, converter detection module 3, sensor input module 4, frequency transformer control module 5 and Power monitor module 6 electrically connects.

PLC master controller is using the control unit of model CPU 226 in the S7-200 series of Siemens Company, S7-200 Series of PLC is applied to all trades and professions, the automatization of detection, monitoring and control in various occasions, and no matter it can make it in independence In operation, or it is connected to the control function that network all enables complexity.Wherein CPU 226 integrated 24 input/16 output totally 40 Digital quantity I/O point.7 expansion modules can be connected, largest extension is to 248 railway digital amount I/O Dian Huo 35 tunnel analog quantity I/O point.Tool Have more input/output points, higher module extended capability, the faster speed of service and with better function be internally integrated special Function.Its input circuit adopts Phototube Coupling, and relay-type exports, and provides reliable work with 24V D/C power for sensor Make voltage.

The Q23SN6LP reflective photoelectric sensor of BANNER company selected by sensor, and its detecting distance reaches as high as 2m, In 0.5-1.5m apart from best results, its running voltage is 10-30VDC, is installed in staircase up or down platform, away from entrance (enable passenger that the acceleration of staircase is done some preparations) at 1.0-1.5m.

SAMCO-i high function squelch type I-IF type selected by converter, selects its two speed to select in the use of converter End 2DF and the second acceleration and deceleration AD2 end are to reach normal and two kinds of speed of low speed and the acceleration meeting occupant comfort sense.

In general, the idle time of escalator is commonly greater than the carrying time.Automatically detect automatically in PLC After staircase no-load running certain time, control converter to make its fall-back, when there being passenger to set foot on escalator bed lid plate, help Ladder can start accelerated service by being arranged on the arrival of the photoelectric induction device automatic sensing passenger of bed lid plate porch.At this In, the Main Function of converter is used to adjust staircase rotating speed, starts and operate steadily, and when nobody, PLC, through time delay, is System automatically proceeds to wriggling state and runs, to reach the purpose of energy-conservation.In staircase porch, photoswitch, when having passenger, light are installed Electric switch sends signal, and, through frequency control to normal speed, after whole passengers leave staircase, staircase is through one section of time delay for staircase Again automatically into the state of receiving guests of low cruise.Electric energy so being saved, reducing mechanical wear thus increasing the service life.Fig. 2 Schematic diagram for power save mode.

When rotating speed being reduced to 20% speed by converter when unloaded, for the motor of below 11kw, staircase consumes energy for only For the 3%～5% of motor rated power, both 300 watts～400 watts about.No matter up or descending, the peristaltic velocity 20% is all Can reach 80% energy-saving effect.

After converter, with extremely low frequency and extremely low voltage, motor can be powered when escalator is unloaded, make to help Ladder is run with slow speed.So, good energy-conserving action can just be played when escalator is unloaded, staircase does not stop simultaneously Run, also staircase will be caused to damage the illusion that cannot run to passenger.When photoelectric sensor detects someone and enters staircase, Staircase just starts to raise speed, and staircase can be set by PLC by the time slowly rising to needed for normal speed, and setting time can It is thought of as 2～4 seconds.When people enters into pedal for escalator, staircase is close to or up normal speed.The personnel that so avoid are helping Accelerator on ladder is it is ensured that the safety of personnel.After PLC detects staircase zero load t second, issuing instructions to converter makes volume Constant speed degree becomes peristaltic velocity again.

Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area Member just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all this technology necks In domain, technical staff passes through logical analyses, reasoning or limited reality on the basis of existing technology according to design of the present utility model Test available technical scheme, all should be in the protection domain being defined in the patent claims.
