Abstract

The utility model discloses a forklift running speed limitation modular switching device, which comprises a global positioning system (GPS) module, a radio frequency identification (RFID) module, a position detection module, a manual control module and a forklift controller, wherein the GPS module, the RFID module, the position detection module and the manual control module are respectively connected with the forklift controller and are used for providing a forklift position signal or a forklift speed selection mode signal for the forklift controller, and the forklift controller is used for comparing the received signal with preset region position characteristic parameter or mode parameter in the forklift controller, calculating a speed limitation value, corresponding to a region, of a forklift, controlling a forklift engine according to the obtained speed through calculation, and limiting the highest running speed of the forklift. By the device, a user can conveniently set different speed limitation on different occasions.

Description

Fork truck travelling speed-limit medelling shifter

Technical field

The utility model relates to the technical field of fork truck, and is especially relevant with fork truck travelling speed-limit medelling shifter.

Background technology

The moving velocity of fork truck can be set.In general, diesel fork lift truck all has speed-limit device, is limited in 18-20 kilometer/hour when dispatching from the factory basically; The moving velocity of storage battery forktruck is to require to be provided with the speed of going under every kind of pattern according to demanding party.

But; The travelling speed-limit that existing fork truck carries all is unique, and fork truck often need be used for different places, as in outdoor, the factory building, in the warehouse or the like; Each place is different to the moving velocity requirement of fork truck; Fork truck actual travel speed still need artificially be controlled by the driver, so, has very big potential safety hazard or operation inconvenience.

The base this, the inventor studies fork truck travelling speed-limit technology, develops a kind of fork truck travelling speed-limit medelling shifter, this case produces thus.

The utility model content

The purpose of the utility model is to provide a kind of fork truck travelling speed-limit medelling shifter, so that client's set different speed restriction in different fields.

To achieve these goals, the solution of the utility model is:

Fork truck travelling speed-limit medelling shifter is made up of GPS (global positioning system) module, RFID (RF identification) module, position detecting module, manual control module and fork truck controller; GPS module, RFID module, position detecting module and manual control module are connected with the fork truck controller respectively, and to the fork truck controller fork truck position signal or fork truck speed selection mode signal are provided; The fork truck controller compares regional location characteristic parameter or mode parameter preset in signal that receives and the fork truck controller; Calculate the cooresponding speed limit in the current region of fork truck by the fork truck controller; Control the fork truck engine by the fork truck controller according to the speed limit of calculating gained again, the maximum travel speed of restriction fork truck.

After adopting said structure; The utility model can make things convenient for the client in different places, as in outdoor, the factory building, in the warehouse or the like, the different speed restriction is set; Both can guarantee fork truck driving safety (particularly going in the small space); Can raise the efficiency (particularly outdoor spacious place) again, significantly reduce potential safety hazard, make things convenient for the fork truck mobility operation.

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed description.

The specific embodiment

With reference to shown in Figure 1, the fork truck travelling speed-limit medelling shifter that the utility model discloses is made up of GPS module 1, RFID module 2, position detecting module 3, manual control module 4 and fork truck controller 5.

GPS module 1 can accurately be measured place, fork truck place coordinate position.

RFID module 2 can be discerned specific objective and read and write related data through radio signals, and need not to set up machinery between recognition system and the specific objective or optics contacts.

Position detecting module 3 is used at the current relative position of indoor detection.

Manual control module 4 is used for the artificial required velocity mode of specifying.

GPS module 1, RFID module 2, position detecting module 3 and manual control module 4 are connected with fork truck controller 5 respectively, and to fork truck controller 5 signal fork truck position signal, perhaps fork truck speed selection mode signal are provided.These several kinds of modules can be connected with fork truck controller 5 separately or be connected with fork truck controller 5 jointly.

Fork truck controller 5 compares predefined regional location characteristic parameter or mode parameter in signal that receives and the fork truck controller 5, and calculates the cooresponding speed limit in the current region of fork truck.Control fork truck engine 6 by fork truck controller 5 according to the speed limit of calculating gained again, thus control wheel 7, the maximum travel speed of restriction fork truck.

For example, the latitude and longitude coordinates of GPS module 1 feedback current location, controller calculates the residing band of position of this coordinate points.According to the band of position, in the parameter list of initial setting up, find cooresponding velocity mode, the extraction rate limits value.According to speed limit, set the input parameter of forklift engine or driver element, for example the size of electric current makes the maximum speed of going of fork truck be limited in the specified scope.

Certainly, the utility model not only can be used for the fork truck travelling speed-limit, and parameter such as can also be used to hoist, turn to is set, and makes the fork truck moving velocity, hoists and turn to etc. all to adopt medelling to switch, and it is more accurate to control, and safety is higher, and efficient is also higher.

More than be merely the preferred implementation of the utility model; It is not qualification to the protection domain of the utility model; All do not have to produce difference in essence with gordian technique the utility model, to the deduction or replace of above-mentioned embodiment, all should be regarded as within the protection domain that falls into this case.
