DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0032] Example:

[0033] like Figure 1 As shown, this embodiment provides a remote control system, which is applied to a mountain orchard monorail conveyor, and includes a remote control 1, a relay networking structure 2 and a remote control switch. The remote control 1 is connected to the remote control switch by a wireless signal through the relay networking structure 2; wherein, the mountain orchard monorail conveyor includes a body 3 and a track 4, the body 3 can move along the track 4, the remote control switch is arranged on the body 3, and is connected to the driver of the body 3, the driver is specifically a brushless motor driver, which is used to drive the linear motion motor of the body 3 to rotate, so that the body 3 moves along the track 4.

[0034] like Figure 1 and Figure 2 As shown, the remote controller 1 includes a power supply 5, a key module 6, a first encoding module 7 and a first wireless transmitting circuit 8. The key module 6 has two output terminals, a left output terminal and a right output terminal, wherein the left output terminal is connected to the power supply 5, and the right output terminal is connected to the input terminal of the first encoding module 7. The output terminal of the first encoding module 7 is connected to the input terminal of the first wireless transmitting circuit 8; further, the power supply 5 adopts a 9V battery, the first encoding module 7 adopts a PT2262 encoder, which integrates a modulation circuit and does not require an additional module, and the first wireless transmitting circuit 8 adopts a 315MHZ high-frequency oscillation transmitting circuit. When no key of the key module 6 is pressed, the first encoding module 7 is not powered on. The source, its 17th pin is at a low level, so the first wireless transmitting circuit 8 does not work. When a button of the key module 6 is pressed, the first encoding module 7 is powered on and works, and its 17th pin is at a high level, and outputs a modulated serial data signal. When the 17th pin of the first encoding module 7 is at a high level, the first wireless transmitting circuit 8 starts to oscillate and transmits a high-frequency signal of equal amplitude. When the 17th pin of the first encoding module 7 is at a low level, the first wireless transmitting circuit 8 stops oscillating. Therefore, the first wireless transmitting circuit 8 is completely controlled by the digital signal output by the 17th pin of the first encoding module 7, thereby completing amplitude shift keying (ASK) modulation on the first wireless transmitting circuit 8, which is equivalent to amplitude modulation with a modulation degree of 100%. The modulation method of amplitude shift keying is simple to modulate and has high bandwidth utilization.

[0035] like Figure 1 and Figure 3 As shown, the relay networking structure 2 includes N+1 repeaters, namely the first repeater, the second repeater, the third repeater, the fourth repeater, the fifth repeater, ... the Nth repeater, the N+1th repeater, from Figure 1 It can be seen that the N+1 repeaters of this embodiment are arranged around the mountain orchard, and the first repeater, the second repeater and the third repeater are arranged on one side of the track 4, the fourth repeater, the fifth repeater ... the Nth repeater and the N+1th repeater are arranged on the other side of the track 4, and the N+1 repeaters are connected in sequence along a certain route; wherein N is a natural number, and if the number of repeaters is not considered, the distance of wireless data transmission can be theoretically reached to infinity, thereby increasing the remote controllability of the mountain orchard monorail conveyor, and each repeater includes a single chip microcomputer 9, a first wireless receiving circuit 10, a first decoding module 11, and a second encoding module The output end of the first wireless receiving circuit 10 is connected to the input end of the first decoding module 11, the output end of the first decoding module 11 is connected to the single-chip microcomputer 9, the single-chip microcomputer 9 is also connected to the input end of the second encoding module 12, and the output end of the second encoding module 12 is connected to the input end of the second wireless transmitting circuit 13; further, the single-chip microcomputer 9 adopts the single-chip microcomputer of the STM32 series, specifically the single-chip microcomputer of the STM32F103 model, the first wireless receiving circuit 10 adopts the superheterodyne receiving circuit, which can greatly improve the anti-interference performance of the signal transmission, and the first decoding module 11 adopts the PT2 272 decoder, can decode the signal received by the first wireless receiving circuit 10, the second encoding module 12 adopts PT2262 encoder, which integrates the modulation circuit, the second wireless transmitting circuit 13 adopts 315MHZ high frequency oscillation transmitting circuit, the serial data signal transmitted by the remote control 1 is received by the first wireless receiving circuit 10 of the first repeater, the first decoding module 11 of the first repeater converts the serial data signal into a parallel data signal, and is read and identified by the single chip microcomputer 9. When no signal is identified, the 17th pin of the second encoding module 12 is low level, so the second wireless transmitting circuit 13 does not work. When a signal is identified, the identified signal passes through the second encoding module 12 of the first repeater, the 17th pin of the second encoding module is at a high level, and a modulated serial data signal is output. When the 17th pin of the second encoding module 12 is at a high level, the second wireless transmitting circuit 13 starts to oscillate and transmits a high-frequency signal of equal amplitude. When the 17th pin of the second encoding module 12 is at a low level, the second wireless transmitting circuit 13 stops oscillating. Therefore, the second wireless transmitting circuit 13 is completely controlled by the digital signal output by the 17th pin of the second encoding module 12, thereby completing amplitude shift keying (ASK) modulation on the second wireless transmitting circuit 13, which is equivalent to amplitude modulation with a modulation index of 100%. The use of amplitude shift keying as a modulation method can greatly improve the anti-interference performance of signal transmission. The signal transmitted by the second wireless transmitting circuit 13 is received and forwarded by the next repeater (i.e., the second repeater) until it is received by the remote control switch.

[0036] like Figure 1 and Figure 4 As shown, the remote control switch includes a second wireless receiving circuit 14, a second decoding module 15 and a relay module 16. The output end of the second wireless receiving circuit 14 is connected to the input end of the second decoding module 15 through the first operational amplifier circuit, and the output end of the second decoding module 15 is connected to the control end of the relay module 16 through the second operational amplifier circuit. Further, the remote control switch adopts a learning remote control switch, which can receive signals from repeaters with multiple different addresses. The second wireless receiving circuit 14 adopts a superheterodyne receiving circuit, which can greatly improve the anti-interference performance of signal transmission. The second decoding module 15 adopts a learning decoding chip, which can decode the signal of the repeater according to the address type of the repeater. The first wireless receiving circuit 14 receives the serial data signal of the relay networking structure 2, and the serial data signal is transmitted to the second decoding module 15 through the first operational amplifier circuit. The second decoding module 15 converts the serial data signal into a parallel data signal, and the parallel data signal is transmitted to the relay module 16 through the second operational amplifier circuit. The relay module 16 controls the driver on the body 3 of the mountain orchard monorail conveyor to realize the remote control of the mountain orchard monorail conveyor.

[0038] S1. In the remote controller 1, when a button of the button module 6 is pressed, the first encoding module 7 outputs a modulated serial data signal, specifically, the first encoding module 7 outputs an amplitude keying modulated serial data signal, which is transmitted by the first wireless transmitting circuit 8;

[0039] S2. In the relay networking structure 2, the first wireless receiving circuit 10 of the first repeater receives the serial data signal transmitted by the remote control 1, and the first decoding module 11 of the first repeater converts the serial data signal into a parallel data signal, which is read and identified by the single-chip microcomputer 9. The identified signal is output as a modulated serial data signal through the second encoding module 12 of the first repeater, specifically, the second encoding module 12 outputs an amplitude keying modulated serial data signal, which is transmitted by the second wireless transmitting circuit 13 of the first repeater, and then received and forwarded by the second repeater until it is received by the remote control switch;

[0040] S3. In the remote control switch, the first wireless receiving circuit 14 receives the serial data signal of the relay networking structure 2, and the serial data signal is transmitted to the second decoding module 15 via the first operational amplifier circuit. The second decoding module 15 converts the serial data signal into a parallel data signal, and the parallel data signal is transmitted to the relay module 16 via the second operational amplifier circuit. The relay module 16 controls the driver on the mountain orchard monorail conveyor body 3 to realize remote control of the mountain orchard monorail conveyor.

[0041] In summary, the system of the present invention designs a relay networking structure composed of a plurality of repeaters, which can greatly improve the distance of wireless data transmission. If the number of repeaters is not considered, the distance of wireless data transmission can theoretically reach infinity, thereby increasing the remote controllability of the mountain orchard monorail conveyor. In addition, the encoding module of the remote control and each repeater of the relay networking structure outputs an amplitude keying modulated serial data signal. The use of amplitude keying as a modulation method can greatly simplify the complexity of amplitude modulation and speed up data transmission.
