0 ti Cup 2019 National Undergraduate Electronic Design Contest title match was announced this morning.
In which the title race is divided into groups of undergraduate and vocational groups:
Bachelor Group:
A wireless charging system for electric car dynamic
B inspection robot
C-line load and fault detecting means
D test instrument a simple circuit
E based on a signal transmission system of the Internet
F sheet count display device
G-way simultaneous voice transmitting and receiving system of the radio
H electromagnetic simulation song shot gun
Higher Group:
the I line of the LED array display device
J Electromagnetic simulation Curved gun
K simple multifunctional liquid container
1. The wireless charging car C is the last race problems, but this design requirements are different, so that the car was last performed climbing, the wireless charging transmitter coil on the road, and this is a circular guide line with a wireless charging transmitter coil distributed over the four circular points, and the state of charge of the car can be determined by sound or light. Although the principle of charging can refer to last year's title race, but the charge and suspended the time and distance needed redesign.
2. The inspection robot is different from tracking the car, the design requirements for the four rotor flying robot chess tracking, logging while achieving power between the two towers. Claims 1. It is noted that the inspection robot may not have "wireless communication and remote control" function. 2. Before takeoff, the aircraft can be manually placed into the take-off point; departure can be controlled manually; the entire inspection process after takeoff not human intervention. 3. Such parts may be added to the tower scan barcode memory functional two-dimensional code.
3. The load detecting means need to achieve fault capacitance, inductance and resistance of the series-parallel structure of the detector at any network element 2-3, while achieving open, short circuit alarm.
4. Simple circuit characteristics tester needs associated with a particular amplifier circuit. As shown below:
Wherein the tester must be able to output a sine wave signal of 1kHz, and automatically measuring the input resistance of the amplifier's output resistance, gain, amplitude-frequency characteristic curve, the play request needs to be done in the case wherein the capacitance and the resistance change or open , the cause of the failure is determined and displayed.
5. The Internet simulation problem is in three cascaded switch LAN.
At the same time we need to make three terminals capture and reproduction output signal, and reproduction signal and the signal acquisition was no significant variation.
6. The paper money detector count display device and looks like, however, are tested 70g of A4 copy paper.
Count measuring at least two plates to realize the measurement of composition 1-10 sheets of A4, while the electrode plate A, B with the wire a, b can not be partially mounted or connected components, other sensors or gauges, but also can be realized from short-circuit detection and calibration of the display.
7. G title race is to achieve a power FM transceiver systems, and enables simultaneous two-way voice. This provides the title and a transmission distance of FM frequencies, at the same time not have significant distortion, peak frequency deviation is not greater than 25kHz. FM modulation of the participants in understanding requirements are relatively high.
8. Electromagnetic simulation Curved gun guns referred to herein, that the need to use runners of Curved barrel projectile hits the target ring. And the target position is an arbitrary position within a specified range, but also so that automatic homing function. Taking into account no other transmit power, the initial emission of the electromagnetic force is calculated for this point in question.
9.LED rotation means, namely linear display LED lamp display apparatus using the principle of persistence of vision, using this principle is the most simple LED lamp water. And this problem is to use 360 degree rotation of the motor LED, and create a graphic input device, a display device so that three different LED dot matrix graphic in the range of 3 120 radians.
10. This same problem guns undergraduate group.
Simple liquid container 11. The multifunctional container of the liquid level can be measured, the weight, type of plastic containers, which play a part only electronic measurement techniques.
These are all topics of this power game, and I hope this competition the students can produce satisfactory work, if you have your own ideas can also share in this post, following is the title match of the tournament secondary electrical accessories.
