Description
Technical field
This utility model is related to material flows automation field, and in particular to a kind of tunnel automatic guided vehicle and guidance system.
Background technology
AGV, i.e. automatic guided vehicle, refer to equipment homing guidance device, can be along the transport vehicle of the guide path of regulation traveling.
As industrial automation level is lifted and currently the demand of logistic efficiency is constantly lifted, increasing warehouse
Used in automatic guided vehicle sorting, transport goods.Conventional guide mode is divided into two big class at present, and a class is that fixed route is led
Draw mode, information media thing is laid come to automatic guided vehicle to guide in guide path, guide mode of the class without fixed route,
The path of advance, such as las er-guidance mode are autonomously generated by program.
What current guide mode did not often make full use of some features under current storage environment to reduce guiding answers
Miscellaneous degree, such as the most frequently used electromagnetism guide mode, this guide mode need electric wire embedded in subsurface, are existed by AC signal
Magnetic field is produced around electric wire, automatic guided vehicle is by detecting the power in magnetic field come along corresponding route；This mode is usually
Larger is changed to environment, quantities is increased, be increased cost.In the utility model patent of Publication No. 102156475A just
A kind of method of electromagnetism guiding is proposed, need to be guided in the corresponding electric wire of embedded underground, quantities is larger.
In the utility model patent of publication number 104102222A, it is proposed that a kind of to utilize laser radar and reflecting plate to calculate
The method of the position of current AGV automatic guided vehicles, needs install more reflecting plate in AGV working environments, without fully profit
With the feature of storage environment so that big to the improvement cost in warehouse using such technical scheme, increase operation cost of enterprises.
Utility model content
The purpose of this utility model is to provide a kind of tunnel automatic guided vehicle, guidance system and its operational approach, using lane
Closed slide in road realizes the straight-line travelling in tunnel, low to warehouse improvement cost, comprising positioner, accurate positioning.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of tunnel homing guidance
Car, comprising car body and the pallet fork that is located on the car body, the pallet fork be can the width of the carbody direction it is two-way stretch out it is double
To pallet fork or can be in the two-way three-dimensional pallet fork that stretch out and can stretch out in front of the car body in the width of the carbody direction, the car body
On be provided with for ensure this kind of tunnel automatic guided vehicle course route guiding device and for position this kind of tunnel from
The positioner of dynamic guiding truck position, the route guiding device include guiding device in tunnel, guiding device in the tunnel
Including for detecting range unit in the tunnel of the car body and both sides object distance.
In this patent document, the bearing of trend for defining the tunnel is fore-and-aft direction, both sides of the shelf in the tunnel,
As left and right directions, different from the pallet fork structure of traditional guiding car, and the pallet fork direction of traditional guiding car is relatively described car
The fore-and-aft direction of body, and in narrow opening, often do not possess the radius of turn of guiding car, guide car cornering difficulties.In this programme,
