Description
Technical field
The utility model relates to a kind of address sniffer, the weak magnetic address of particularly a kind of AGV three polarity sniffer.
Background technology
The guidance mode of AGV (Automatic Guided Vehicle) trackless automatic guide vehicle mainly contains modes such as electromagnetic induction guiding, laser aiming and the guiding of magnet gyro; Wherein because the development of magnetic bootstrap technique in recent years; Used weak magnetic sticker guide line and weak magnetic guiding sniffer, made this technology different, become convenient, reliable, practical with the mode of early stage pre-buried high magnetic steel guiding and detection; Be easy to construction, so this technology is developed with fast speeds.
The trackless automatic guide vehicle of this weak magnetic guidance can not accomplished the carrying of object under the situation of people's supervision, can need be sticked on the road of traveling straight line and curve easily by the people, and carrier can be according to these circuit operations.As to change route, only need to change joint strip and then can conveniently accomplish.Simultaneously, laterally on the vertical direction, increase the short joint strip of same material, can form the address mark on the road, supply the Address Recognition of automatic guide vehicle, carry out various operations through stored count at guiding route.
But, in application, there are a little problems, lot of reinforcing steel bar has been used on the cement of trackless automatic guide vehicle erecting stage pouring ground, if install improperly, has brought partly magnetization to reinforcing bar, weak magnetic guiding is surveyed caused interference.Particularly because the address adopts when surveying is relative address, if, this task that causes this truck system is all slipped up in case disturbing effect to misreading the address, and has been remembered this misaddress.
In order to solve above problem, applied for utility model patent in 2010, name is called " the weak magnetic address of two magnetic sniffer ", and effectively the low-intensity magnetic field of the slow variation of ground shielding reinforcing bar magnetization generation is to the influence of address read knowledge.
But when the trackless automatic guide vehicle carried out the complicacy operation, the turning in path intersected, when making the weak magnetic address of two magnetic sniffer through the magnetic guide line, because the magnetic field edge effect of magnetic guide line can cause the address to misread.Because what adopt when the address is surveyed is relative address, in a single day, and remembered this misaddress if misread the address, this task that causes this truck system is all slipped up.Address this problem at present, adopt magnetic address sniffer a little less than two magnetic of trackless automatic guide vehicle is deducted through this part guide line of guide line, though can partly deal with problems like this, caused following shortcoming: 1) software processes complicacy; 2) the guiding reliability of operation of trackless automatic guide vehicle reduces; 3) many places, on-the-spot path cut off, and influence neat and artistic.
The utility model content
The utility model technical matters to be solved be to provide a kind of recognize read the weak magnetic address of the high AGV of address accuracy rate three polarity sniffer.
In order to solve above technical matters; The utility model provides the weak magnetic address of a kind of AGV three polarity sniffer; This sniffer is contained in the airtight electrical equipment box; This electrical equipment box is installed on trackless automatic guide vehicle side bottom; The baseplane direction of this electrical equipment box is parallel with the traffic direction of trackless automatic guide vehicle, this electrical equipment box inner before, during and after end respectively be provided with forward, reverse, forward probe circuit, and be pasted with parallel forward, reverse, forward address magnetic joint strip on forward, reverse, the corresponding road in forward probe circuit position; Forward, reverse, forward probe circuit detect forward, reverse, forward address magnetic joint strip, the accurate operation of the automatic carrier loader of OPADD signal controlling respectively.
Said forward, reverse, forward address magnetic joint strip be separated by spacing with forward, oppositely, forward probe circuit spacing is identical, direction is identical.
Described forward address magnetic joint strip, when it is pasted the magnetic field S utmost point up, magnetic field intensity is 100 Gausses.
Described reverse address magnetic joint strip, when it is pasted the magnetic field S utmost point down, magnetic field intensity is 100 Gausses.
Said trackless automatic guide vehicle forward, lower part is equipped with the guiding sniffer, and is pasted with magnetic joint strip a little less than the path of navigation on this corresponding road in guiding sniffer position.
The weak magnetic joint strip of said path of navigation with each bar forward, oppositely, forward address magnetic joint strip is vertical.
The superior effect of the utility model is:
1) because the weak magnetic joint strip of all path of navigation is the output of having only unidirectional forward magnetic field; The edge effect in its magnetic field also only has anti-, positive and negative possibility separately; Definitely there is not possibility positive and negative, just separately; The edge effect that is guide line again can not cause misreading of address, has improved and has recognized the accuracy rate of reading the address.

Embodiment
See also shown in the accompanying drawing, the utility model is done further to describe.
As shown in Figure 1; The utility model provides the weak magnetic address of a kind of AGV three polarity sniffer; This sniffer is contained in the airtight electrical equipment box 2; This electrical equipment box 2 is installed on trackless automatic guide vehicle 1 side bottom; The baseplane direction of this electrical equipment box 2 is parallel with the traffic direction of trackless automatic guide vehicle 1; End respectively is provided with forward probe circuit M8, reverse probe circuit 9, forward probe circuit N10 before, during and after these electrical equipment box 2 inside; Be pasted with parallel forward address magnetic joint strip A3, reverse address magnetic joint strip 4, forward address magnetic joint strip B5 on forward probe circuit M8, reverse probe circuit 9, the corresponding road in forward probe circuit N10 position, forward probe circuit M8, reverse probe circuit 9, forward probe circuit N10 detect forward address magnetic joint strip A3, reverse address magnetic joint strip 4, forward address magnetic joint strip B5, the accurate operation of OPADD signal controlling trackless automatic guide vehicle 1 respectively.
Said forward address magnetic joint strip A3, reverse address magnetic joint strip 4, forward address magnetic joint strip B5 be separated by spacing and forward probe circuit M8, oppositely probe circuit 9, forward probe circuit N10 spacing are identical, direction is identical.
Described forward address magnetic joint strip A3, B5, when it is pasted the magnetic field S utmost point up, magnetic field intensity is 100 Gausses.
Described reverse address magnetic joint strip 4, when it is pasted the magnetic field S utmost point down, magnetic field intensity is 100 Gausses.
Said trackless automatic guide vehicle 1 forward, lower part is equipped with guiding sniffer 6, and is pasted with magnetic joint strip 7 a little less than the path of navigation on this corresponding road in guiding sniffer 6 positions.
The weak magnetic joint strip 7 of said path of navigation is vertical with each bar forward address magnetic joint strip A3, reverse address magnetic joint strip 4, forward address magnetic joint strip B5.
As shown in Figure 2; Because the weak magnetic joint strip 7 of all path of navigation has only the output in unidirectional forward magnetic field; The edge effect in its magnetic field also only has anti-, positive and negative possibility separately, does not definitely have possibility positive and negative, just separately, i.e. the edge effect of the weak magnetic joint strip of path of navigation again can not cause misreading of address; So have only forward probe circuit M8, forward probe circuit N10 to detect the positive flux field of corresponding amplitude; When simultaneously reverse probe circuit 9 detects the counter magnetic field of corresponding amplitude, unique address signal output is arranged, improved and recognized the accuracy rate of reading the address.
