Description

Technical Field

[0001] The invention belongs to the technical field of plant sound wave growth promotion, and in particular relates to a plant sound wave growth promotion device with insect repelling and killing function and a control method. Background Art

[0002] At present, the growth and output of plants depend to a large extent on pest control and the quality of natural climate. Pests will seriously affect the growth rate and yield level of plants. At the same time, natural climate also determines the growth rate and yield level of plants to a large extent. Regarding pest control, in order to ensure the normal growth and high yield of crops, trees, medicinal materials and other plants, chemical agents are currently mainly used for pest control. In the field of plant growth promotion, fertilizers or chemical growth promoters are also often used to increase growth rate and yield. In recent years, with the gradual strengthening of green and environmental protection concepts, healthy diet has become a focus of attention. The long-term, hidden and continuous harm of chemical reagents to the human body, as well as environmental pollution and ecological damage have become increasingly prominent. The development of green and environmentally friendly, harmless to life and health, and non-destructive to the ecology of plant pests Physical control and growth promotion technology will become an important technology in the future.

[0003] The basic principle of sonic wave pest control is to use sound waves to act on the eggs, larvae and adults of pests, and use the physical effects of sound wave vibration, cavitation and other effects to destroy their tissue structure to achieve the purpose of pest control. At the same time, the high-intensity physical field generated by sound waves will cause strong discomfort to the larvae and adults of pests, so that they will be killed or flee from the plants protected by sound waves due to fear of the destructive effect of sound waves on their bodies. Compared with chemical pesticide control methods, sonic wave pest control has significant advantages such as no pesticide residue, no continuous environmental pollution, and no damage to the ecology. The current sonic insect repellent device is derived from the traditional audio equipment, and can generally only be placed in the plant bushes like the audio equipment, which brings the following problems: First, ultrasonic waves are generally used for insect repellent, and ultrasonic waves are directional. In order to protect plants in all directions, multiple sonic insect repellent devices have to be manually arranged in all directions, which is very inconvenient to use, and users without professional knowledge of sonic waves cannot use these devices well, which requires the personnel to have a high level of technical skills; Second, since the attenuation of sound waves is proportional to the square of the frequency, ultrasonic waves have a high frequency and naturally decay quickly. If the traditional sonic insect repellent device is to ensure that the plants are very close to the ultrasonic sound source, it can only be moved to perform close-range insect repellent on the plants one by one. Unlike insect repellent with chemicals, sonic insect repellent must act on the plants for several minutes or even dozens of minutes before it can take effect. The traditional sonic insect repellent device can only expel insects one by one, which is inefficient and consumes a lot of manpower, which greatly limits its practical application.

[0004] In the field of plant growth promotion, fertilization and application of chemical growth promoters are generally used. The application of chemical growth promoters also has the problem of pesticide residues, continuous environmental pollution, ecological damage, and thus affects people's health. Acoustic growth technology has been proven to effectively promote plant growth and increase yields. In the literature such as "Application of Plant Acoustic Growth Technology in Agriculture" ("Agricultural Engineering", Issue 3, 2015) and "Application of Acoustic Growth Technology in Plant Growth" ("Rural Economy and Science and Technology", Issue 2, 2019), it has been confirmed through experiments that after the ultrasonic growth equipment is applied to tomatoes, cucumbers, celery, lettuce, cabbage, jujube trees, peach trees, grapes, flowers, etc., crops with a slightly shorter growth period (such as tomatoes, cucumbers, celery, etc.) are put on the market 10 to 20 days earlier, with an average increase of 10 to 20%, increasing benefits, and at the same time being pest-free, saving pesticide costs. However, just as the ultrasonic insecticide device is derived from traditional audio equipment, the ultrasonic growth promotion device also has significant problems such as when a single device is fixed, the effective range of a single device is generally tens of meters, and the plants at a distant distance receive little sound wave energy. The use of plant-by-plant growth promotion will consume a lot of manpower, material and financial resources, which is not conducive to large-scale promotion and application.

[0005] Through the above analysis, the problems and defects of the prior art are as follows:

[0006] (1) Existing ultrasonic pest control devices cannot apply ultrasonic energy to plants at close range. When it comes to pest control of large areas of plants, it is time-consuming, laborious, and inefficient.

[0007] (2) It cannot produce strong sound wave energy directly on plant roots. Long-distance sound wave propagation wastes a lot of energy, is inefficient, complex to use, wasteful, and difficult to apply on a large scale. Summary of the invention

[0008] In view of the problems existing in the prior art, the present invention provides a plant sound wave growth-promoting device with insect repelling and killing function and a control method.

[0009] The present invention is implemented in this way: a plant sound wave growth-promoting device with insect repelling function is provided with:

[0010] A plant storage module, the plant storage module is used to store plants, and the plant storage module is equipped with a sound wave generating device;

[0011] The plant storage module is connected to a driving module, the driving module is provided with a driving circuit, and a power supply and a switch are installed at the front end of the driving circuit;

[0016] Furthermore, the driving circuit is provided with a non-volatile memory, a signal processing module, a parameter setting wireless module and a DA converter. The DA converter is provided with a frequency divider group and a power amplifier group. The frequency divider group is composed of a plurality of frequency dividers, namely frequency divider 1, frequency divider 2, ... frequency divider n. The power amplifier group is composed of power amplifier 1, power amplifier 2, ... power amplifier n. The frequency dividers and power amplifiers are connected in a one-to-one correspondence. The frequency dividers are divided into mid-audio frequency dividers (frequency divider 1) and ultrasonic frequency dividers (frequency dividers 2 to n) according to their positions. The ultrasonic frequency dividers are divided according to the frequency band response segment of the ultrasonic transducer connected to the device, and can be divided into 2 to n groups with a total of n-1 groups, and n is no more than 9 at most, that is, the number of ultrasonic frequency band groupings does not exceed 8 groups.

[0017] Furthermore, the non-volatile memory is mainly composed of fast flash memory, which is used to store preset sound wave digital sequences or parameters for repelling insects and promoting growth. The signal processor can directly call the preset sound wave digital sequences or parameters for repelling insects or promoting growth to generate corresponding sound wave digital signals.

[0018] Furthermore, the signal processing module is composed of a single chip microcomputer, a digital signal processor (DSP), a field programmable gate array (FPGA) or an embedded (ARM) chip or a combination thereof to form a signal processing unit, and contains a memory and a peripheral interface. The signal processing module will detect whether there is an update setting request from the parameter setting wireless module at each startup, and if there is, the parameters sent by the parameter setting wireless module need to be written into the initialization program of the signal processing program, and the parameters used to update the initialization program after the user submits the setting completion instruction.

[0019] Furthermore, the parameter setting has a wireless module, which is composed of a wireless data transmitter such as Bluetooth and WiFi for data transmission. It is connected to the user's mobile phone and computer client wirelessly through the wireless data transmitter, and the parameter setting of the device is completed through the user's mobile phone and computer client.

[0020] Furthermore, the control method of the plant acoustic wave growth promoting device with insect repelling function is:

[0024] Step 4: The audio speaker and the transducer array act on the plants through physical signals to promote plant growth and eliminate insects, thus completing the operation.

[0025] Furthermore, the priority of the signal processing module receiving the parameter setting wireless module and the non-volatile memory signal is: the signal processing module reserves 5 to 10 seconds to detect whether there is a parameter change request from the parameter setting wireless module, and if so, waits for the user to input the changed parameters, and if not, initializes the system with the default parameters; the system initialization mainly arranges the execution task table, and extracts the preset signal digital sequence corresponding to the plant insect repellent and growth promotion into the memory, or directly generates the signal digital sequence corresponding to the plant insect repellent and growth promotion according to the parameters modified by the user or the system default parameters.

[0026] Furthermore, the parameter setting wireless module performs data setting through the user's mobile phone or computer client, including but not limited to the frequency, amplitude, waveform parameters of the insect repellent and growth waveform, the start time, end time, cycle period of the insect repellent, the start time, end time and cycle period of the growth, etc. After completing the parameter setting, the signal processing module initializes the device program according to the setting parameters. If the user parameter setting requirements are not detected, the system default working parameters are called to initialize the device program, mainly setting the device working parameters. If there are new waveform parameters, a new waveform will be generated with them, and the new waveform will be stored in the non-volatile memory flash. After the program initialization is completed, the signal processing module calls the sound wave waveform digital sequence in sequence according to the task execution table formed by the initialization, or generates a digital sequence according to the waveform parameters, and then converts it into a corresponding analog electrical signal through the DA converter.

[0027] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0028] First, in view of the technical problems existing in the above-mentioned prior art and the difficulty of solving the problems, the technical solutions to be protected by the present invention and the results and data during the research and development process are closely combined to analyze in detail and deeply how the technical solutions of the present invention solve the technical problems, and some creative technical effects brought about after solving the problems. The specific description is as follows:

[0029] The present invention places the transducer array used for sonic insect repelling and sonic growth promotion directly under the soil of the cultivated plants, realizing the integration of plant planting and sonic insect repelling and sonic growth promotion functions. Since the transducer is very close to the plant, the energy of the sound wave can act on the plant very intensively, and compared with the traditional sonic insect repelling and sonic growth promotion device, its efficiency and effect can be greatly improved. The integrated design of plant planting and sonic insect repelling and sonic growth promotion functions allows the two most important aspects of plant growth, namely pest control and growth promotion, to be taken into account, and solves the significant problems caused by chemical agent control, such as pesticide residues, continuous environmental pollution, ecological damage and health impact.

[0030] Second, considering the technical solution as a whole or from the perspective of the product, the technical effects and advantages of the technical solution to be protected by the present invention are described in detail as follows:

[0031] The plant sonic growth-promoting device with insect repelling function of the present invention can effectively solve the problems of low efficiency, high use requirements and difficulty in large-scale use of traditional sonic insect repelling and sonic growth-promoting devices.

[0032] Third, as auxiliary evidence of the inventiveness of the claims of the present invention, it is also reflected in the following important aspects:

[0033] The expected benefits and commercial value after the technical solution of the present invention is transformed as follows: green and environmentally friendly plant pest control and growth promotion in agriculture, forestry and traditional Chinese medicine industry are the main themes of the future development of these fields. The plant acoustic wave growth promotion device with insect repellent function of the present invention can effectively solve the problems of low efficiency, high use requirements and difficulty in large-scale use of traditional acoustic wave insect repellent and acoustic wave growth promotion devices. It can be widely used in physical plant insect repellent and growth promotion in agriculture, forestry and traditional Chinese medicine industry, and can also be used in the field of plant insect control and growth promotion in special environments such as space and satellite orbits that have strict requirements on the use of chemical agents. It will be an important invention for the practical application of acoustic wave insect repellent and growth promotion technology, which can open up an emerging product field with huge expected benefits and commercial value.

[0034] The technical solution of the present invention solves the technical problems that people have been eager to solve but have never been successful: solving the problems of continuous environmental pollution, ecological environment damage, and harm to human health caused by chemical agents in plant production has long been a major global problem. In recent years, as green and environmental awareness has gradually increased and become the main theme, green and environmentally friendly pest control and physical technology for plant growth and production increase have been technical problems that people have long been eager to achieve but have not been successfully realized. The plant sonic growth-promoting device with insect repelling and killing function of the present invention overcomes the typical defects of traditional sonic insect repelling and growth-promoting devices, such as low efficiency, difficulty in large-scale use, and inability to take into account both pest control and growth and production increase, and provides a tool with significant effectiveness for plant production in the fields of agriculture, forestry, and traditional Chinese medicine.

The control method of the plant sound wave growth promoting device with insect repelling function as claimed in claim 6, characterized in that: The priority of the signal processing module receiving the parameter setting wireless module and the non-volatile memory signal is: the signal processing module reserves 5 to 10 seconds to detect whether there is a parameter change request from the parameter setting wireless module, and if so, waits for the user to input the changed parameters, and if not, initializes the system with the default parameters; system initialization is to arrange the execution task table, and extract the preset signal digital sequence corresponding to plant insect repellent and growth promotion into the memory, or directly generate the signal digital sequence corresponding to plant insect repellent and growth promotion according to the parameters modified by the user or the system default parameters.

8. The control method of the plant sound wave growth promoting device with insect repelling function as claimed in claim 6, characterized in that: The parameter setting wireless module performs data setting through the user's mobile phone or computer client, including the frequency, amplitude, waveform parameters of the insect repellent and growth waveforms, the start time, end time, and cycle period of the insect repellent, and the start time, end time, and cycle period of the growth; after completing the parameter setting, the signal processing module initializes the device program according to the set parameters. If the user parameter setting requirement is not detected, the system default working parameters are called to initialize the device program, set the device working parameters, and if there are new waveform parameters, a new waveform will be generated with them, and the new waveform will be stored in the non-volatile memory flash. After the program initialization is completed, the signal processing module calls the sound wave waveform digital sequence in sequence according to the task execution table formed by the initialization, or generates a digital sequence according to the waveform parameters, and then converts it into a corresponding analog electrical signal through a DA converter.
