[0050] Optionally, the information processing module 5 uses an stm32F103 single-chip microcomputer.

[0051] By transmitting the measurement data to the information processing module 5, data processing is performed to determine whether the reaction is proceeding normally and whether the reaction is completed. The information processing module 5 can process the data transmitted from each module, perform data analysis and recording, ensure the provision of comprehensive and organized data results, and provide support for further analysis and processing.

[0052] The detection module 6 includes: a signal collection module 9, an infrared light emission device 10, a light shielding device 11, an annular pressure sensor 12, and a double-layer shell 13.

[0053] Specifically, the signal collection module 9 uses a photosensitive sensor. The infrared light emission device 10 has a TCRT5000L type reflective optical sensor. The annular pressure sensor 12 uses an FSR402 thin-film annular pressure sensor.

[0054] The double-layer shell 13 includes an inner layer shell 17 and an outer layer shell 18.

[0055] The outer layer shell 18 is connected to the upper end of the robotic arm 3, and the display module 19 is located on the outer shell of the trolley body.

[0056] Specifically, the outer layer shell 18 uses a magnet with magnetism to cooperate with an external light shielding device 14 to complete the switching of the external light shielding device 14.

[0057] The infrared light emission device 10 is arranged inside the outer layer shell 18 and is evenly and symmetrically distributed on its inner side, and is used to emit infrared light with a corresponding wavelength to provide an environment for detecting data.

[0058] The signal collection module 9 is arranged at the bottom end of the inner layer shell 17, and is used to amplify the received signal and process the optical signal after the infrared light emitted by the infrared light emission device 10 passes through transmission and diffuse reflection.

[0059] Specifically, the external light shielding device 14 uses a patch and is arranged around the opening of the outer layer shell 18, and is used to shield light after the sample enters the detection device, so as to avoid the situation that the measured data is inaccurate due to the interference of external infrared light.

[0060] The internal light shielding device 15 is arranged at the bottom end inside the inner layer shell 17 and surrounds the signal collection module 9 in a circle, and is used to exclude the optical signal emitted by the infrared light emission device 10 but not passing through the sample.

[0061] The annular pressure sensor is arranged at the opening edge of the inner shell 17, and is used to judge whether the sample reaches the specified position, and send a working instruction to the signal collection module 9 after the sample reaches the specified position.

[0062] The annular pressure sensor 12 is electrically connected to the power supply module 16.

[0063] The light-shielding device 11 includes an outer shell 18, a light-shielding device 14 and an internal light-shielding plate 15. The light-shielding device 14 of the outer shell 18 is arranged at the upper opening of the outer shell 18.

[0064] Specifically, the outer shell 18 is a cylinder with a necking structure at the top. The light-shielding device 14 of the outer shell 18 is a conical ring, and the light-shielding device 14 of the outer shell 18 is sleeved on the top of the outer shell 18.

[0065] The internal light-shielding plate 15 is arranged around the inside of the inner shell 18 outside the signal collection module 9.

[0066] A plurality of the infrared light emitting devices 10 are arranged in the inner wall of the inner shell 17. For the target object, the infrared light adopted by the present invention has a better effect.

[0067] The inspection module of the present invention realizes the collection of information of the sample fruit, can build a simple mobile darkroom outdoors, provides more accurate information, helps fruit farmers or scientific research personnel collect relevant data, collect suitable fruits, and provides certain reference materials for cultivating the target fruit.

[0068] The double-layer shell structure can effectively construct an optical darkroom. The outer shell 18 isolates the influence of natural light on the measurement result, and the inner shell 17 isolates the influence of the optical signal that has not passed through the sample (that is, the optical signal that does not carry the sample information). The double-layer shell structure can effectively exclude the influence of non-target optical signals on the measurement result and make the result more accurate.

[0069] The image acquisition module 4 collects image information, reasonably plans the route, cooperates with the beacons set in the site to judge its own position, and realizes effective unmanned management. Through the communication module, the trolley communicates with the outside, receives the instructions sent by the outside, and at the same time sends the collected data to the external terminal, realizing the complete unmanned data collection work in the planting area.

[0070] The driving module 2 can receive the instructions issued by the information processing module, control the movement of the whole unit, approach the target sample, can extend the effective working time, and can obtain more data within a limited time.

[0071] The signal processing module 91 can collect the optical signal transmitted through the sample fruit, first convert the optical signal into an electrical signal, then into a digital signal, and send the digital signal to the information processing module. By using a step-by-step conversion method, the signal can be effectively amplified and analyzed, making the final data more accurate.

[0072] The light-shielding device 11 blocks the interference of non-target light through physical means to construct an outdoor optical darkroom. The double-layer light-shielding device inside and outside can more effectively eliminate interference. At the same time, the mechanical design of the external light-shielding device can achieve high efficiency and no energy consumption. The internal light-shielding device 15 is made of solid plastic and surrounds the signal collection module. The design of the two light-shielding devices 11 can maximize the construction of the darkroom environment at the lowest cost and ensure the accuracy of the collected data.

[0073] Embodiment 2 In this embodiment, the torque of the motor of the drive module 2 is 1298 N.

[0074] In this embodiment, the annular pressure sensor 12 includes a piezoresistive sensor and an electromagnetic relay switch that are electrically connected to each other.

[0075] In this embodiment, the signal collection module 9 is a photosensitive sensor and is electrically connected to an ADC analog-to-digital converter.

[0076] In this embodiment, the display module 19 is an OLED screen.

[0077] In this embodiment, the signal processing module 91 is an STM32 single-chip microcomputer.

[0078] In this embodiment, the target fruit is grapes.

[0079] The working method of the intelligent trolley for growth tracking and quality monitoring includes the following steps: The first step is to send a signal to the communication module 7 through an external device. After receiving the signal, the trolley starts to work. The modules that start to work at this time include the image acquisition module 4, the signal processing module 91, and the drive module 2.

[0080] The second step is to collect the external image in real time through the image acquisition module 4 and search for the target. After being processed by the signal processing module 91, a spatial coordinate positioning is generated, and an instruction is sent to the drive module 2. The drive module 2 controls the trolley to approach the target sample. After real-time route correction, it reaches directly below the grape sample.

[0081] The third step is that after reaching the specified location, the robotic arm 3 is activated, the spatial coordinate information is converted into a servo angle control instruction, control information is sent to the control board through the STM32F103C8T6 single-chip microcomputer, and the detection module 6 is brought close to the target by using the robotic arm 3, and waits for the detection to end while maintaining the position.

[0082] Step 4: Move the detection module 6 close to the grape sample so that the grape sample passes through the opening of the outer shell 18 of the detection module 6. By virtue of the gravity of the grape sample, the iron sheet of the external light-shielding device is squeezed downward into the inner part of the outer shell 18. At the same time, the iron sheet originally attached to the outer shell 18 by magnetic attraction leaves the outer shell 18. After the grape sample enters the space between the outer shell 18 and the inner shell, it becomes a light-shielding sheet to enclose the grape sample between the outer shell 18 and the inner shell.

[0083] Based on the electrical signal generated by the annular pressure sensor 12 under the pressure of the target object, it is determined whether the target reaches above the detector and completely shields the external light source.

[0084] Step 5: The grape sample touches the annular pressure sensor 12 at the opening of the inner shell 17, sending a signal to turn on the infrared light emitting device 10 and the signal collection module 9 in sequence. The infrared light emitting device 10 emits a signal, and the signal collection module 9 converts the collected optical signal into an electrical signal. Then, the ADC analog-to-digital converter converts the electrical signal into a digital signal and sends it to the signal processing module 91.

[0085] Step 6: The signal processing module 91 corresponds the received digital signal to the corresponding component concentration according to the conversion formula, records this data and sends it to the external terminal through the communication module 7.

[0086] Step 7: Repeat Step 2 to Step 6, continuously collect data until the set target is reached or an external termination signal is received.

[0087] In the above embodiments, the device elements involved are all conventional device elements unless otherwise specified. The structural setting methods, working methods or control methods involved are all conventional setting methods, working methods or control methods in this field unless otherwise specified.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
