Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.
Example 1
In the wireless charging process of AGV's removal, the mode that the rectangular guide rail that the transmitting coil that sets up at the transmitting terminal generally adopted was laid adopts the transmitting guide rail to indicate this mode of laying in this application, and as receiving arrangement's partly, AGV's receiving terminal then is located the top of transmitting guide rail.
There is receiving coil in the receiving end of AGV, and receiving coil mainly comprises triplex: the device comprises a main coil, a left position detection coil and a right position detection coil. The left position detection coil and the right position detection coil are respectively positioned at two sides of the main coil, and the main coil is realized by a power pickup coil.
The special winding method claimed by the application is specifically that the thickness of the litz wire wound to form the main coil is larger than the thickness of the litz wire wound to form the left position detection coil and the right position detection coil, the litz wire of the main coil is thick and is used for carrying out power transmission signals, and the left position detection coil and the right position detection coil are relatively thin and are used as detection signals.
The power pickup coil serving as the main coil is provided with a matching network corresponding to the power pickup coil, the corresponding matching network is an adjusting network connected with the main coil, the output end of the adjusting network is connected with a load, and a magnetic core covers the winding area of the main coil. The left position detection coil is also connected with a matching network corresponding to the left position detection coil, no magnetic core is covered above the litz wire in the winding area, the matching network corresponding to the right position detection coil is connected with the same right position detection coil, and no magnetic core is covered above the litz wire in the winding area; the left position detection coil and the right position detection coil are connected in the same matching network mode, and are connected with a rectification circuit after being connected with a series capacitor, and the output end of the rectification circuit is connected with a detection voltage circuit. According to fig. 1, the receiving coil is divided into three areas, the main coil is a power receiving coil, and a magnetic sheet is required to cover the upper part of the power receiving coil to enhance the coupling degree; the left position detection coil and the right position detection coil are arranged above the magnetic sheet, and the magnetic sheet does not need to be covered, so that the weight of the automobile body and the power consumption can be reduced.
The magnetic field distribution generated by the long guide rail transmitting coil is approximately uniform, and the voltages generated by the left position detecting coil and the right position detecting coil and the corresponding matching networks are approximately equal. Because there are factors such as material discreteness in the actual production process, this application is compared with the threshold value of presetting according to the voltage difference value that left and right sides position detection coil respective coupling produced, and then AGV receiving coil aligns with the transmitting terminal according to threshold value judgement, and then has guaranteed the charging efficiency of system.
In fig. 2a to 2c, the primary winding is used with different tuning networks according to the load. The left position detection coil and the right position detection coil must be compensated by a series capacitor C after rectification, the capacitors C are connected in series between the inductor and the rectification circuit, and the output end of the rectification circuit is connected with a detection voltage circuit.
Suppose the input voltage of the transmitting device is U, the inductance of the transmitting rail is L, and the mutual inductance between the transmitting rail and the receiving coil is M. It can be obtained that the voltage after the series compensation and rectification of the receiving coil and the capacitor isI.e. the ratio of pi MU to 2L √ 2. It can be seen that in normal operation this voltage is only related to M, i.e. to the relative position between the transmit rail and the receive coil, where the voltage resulting from the coupling of the left position detection coil is denoted U left and the voltage resulting from the coupling of the right position detection coil is denoted U right.
The receiving end of AGV dolly with launch under the condition that the guide rail was aimed at, the voltage value that the position detection coil that is located main coil both sides produced is the same, because production process error the utility model discloses in interim 0.1V be the voltage difference threshold value when main coil and launch the guide rail alignment position. In fig. 3a to 3c, if the voltage difference between the left voltage U obtained by coupling the left position detection coil and the right voltage U obtained by coupling the right position detection coil is lower than the threshold, the transmitting coil is directly opposite to the receiving coil, and the AGV is not required to be adjusted.
When the receiving coil is shifted to the right, that is, the center line of the main coil is shifted to the right of the guide rail, as shown in fig. 3b, the voltage difference between the voltage coupled by the left position detecting coil and the voltage coupled by the right position detecting coil is higher than the threshold, and the voltage coupled by the left position detecting coil is higher, at this time, the AGV needs to be controlled to shift to the left.
When the receiving coil is biased to the left, that is, the center line of the main coil is biased to the left direction of the guide rail, as shown in fig. 3c, the voltage difference between the voltage coupled by the left position detecting coil and the voltage coupled by the right position detecting coil is higher than the threshold, and the voltage coupled by the right position detecting coil is higher, at this time, the AGV needs to be controlled to be biased to the right.
The relative position between the main coil of the AGV trolley and the launching guide rail is adjusted through the judgment between the voltage difference and the threshold value, the coupling degree of the launching coil of the receiving coil is guaranteed, the system cost is reduced, and therefore the wireless charging efficiency of the AGV is improved.
