Detailed implementation manners

[0025] To make the purpose, technical solutions and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] Please refer to Figure 1-8A soil detector provided by the utility model, the soil detector includes a main unit 1 and a detector 2. The detector 2 is used to detect data of the plant growth environment, such as environmental temperature, soil humidity, light, pH value, fertility, nitrogen fertilizer, potassium fertilizer or phosphate fertilizer, etc. The detector 2 is wirelessly connected to the main unit 1, and the wireless communication connection is used to realize the wireless communication between the main unit 1 and the detector 2; that is to say, through the wireless communication connection between the main unit and the detector, when the detector and the main unit are automatically paired and connected, the data detected by the detector can be transmitted to the main unit through wireless communication, so as to realize the remote monitoring of soil data without the user being present to monitor the detection data in real time, which brings convenience to the user when detecting soil data; The wireless communication can be Bluetooth, wireless local area network, Bluetooth, mobile communication, radio frequency identification, infrared ray, satellite communication, radio broadcast, etc. The wireless communication in this embodiment uses one of the above, that is, the wireless communication is a prior art, and how the wireless communication between the main unit and the detector is realized will not be elaborated here.

[0027] In this embodiment, as Figure 1 , 4 and shown in 6, the wireless communication includes a signal transmitter 31 and a signal receiver 32. The signal transmitter 31 is used for signal transmission, and the signal receiver 32 is used to receive the signal sent by the signal transmitter. The signal receiver 32 is arranged on the main unit 1 and is electrically connected to the main unit 1. The signal transmitter 31 is arranged on the detector 2 and is electrically connected to the detector 2. The data detected by the detector 2 is transmitted to the signal receiver 32 through the signal transmitter 31, and the signal receiver 32 transmits the received data to the main unit 1. The main unit 1 displays the data through the display screen of the main unit; The transmitter is a device used to convert an electrical signal into a wireless signal and transmit it to the receiver, and the receiver is a device that receives the wireless signal and converts it into an electrical signal for output. That is to say, the signal transmitter 31 converts the data detected by the detector 2 into a wireless signal and transmits it to the signal receiver 32, and the signal receiver 32 converts the received wireless signal into an electrical signal and outputs it to the main unit 1, so that the main unit can receive the data detected by the detector 2 and display it on the display screen of the main unit. Both the transmitter and the receiver are prior arts, and the principles of the transmitter and the receiver will not be elaborated here.

[0028] In this embodiment, as Figure 4 and 6 shown, both the signal transmitter 31 and the signal receiver 32 are antennas. The antenna is a prior art. The cost of the antenna is relatively lower than that of other transmitters and receivers, and the overall production cost of the soil detector can be reduced.

[0029] In this embodiment, as Figure 1 , 4, as shown in FIGS. 6, the detector 2 includes a detector body 21, a first control circuit board 22 and a detection module 23. The first control circuit board 22 and the signal transmitter 31 are both disposed within the detector body 21. The detection module 23 is disposed on the detector body 21. Both the detection module 23 and the signal transmitter 31 are electrically connected to the first control circuit board 22. The host 1 includes a host body 11 and a second control circuit board 12. The signal receiver 32 and the second control circuit board 12 are disposed within the host body 11. The signal receiver 32 and the second control circuit board 12 are electrically connected to the second control circuit board 12. The first control circuit board 22 collects detection data through the detection module 23. The detection data collected by the first control circuit board 22 is then transmitted to the signal receiver 32 through the signal transmitter 31. The signal receiver 32 transmits the received detection data to the host 1. The detection data of the detection module of the detector 2 is displayed on the host for the user to view the detection data. In this embodiment, the first control circuit board 22 is disposed on the first control circuit board 220 of the detector body 21, and the first control circuit board 220 is disposed within the detector body 21. In this embodiment, the second control circuit board is disposed on the second control circuit board 120 of the host, and the second control circuit board 120 is disposed within the host body 11.

[0030] In this embodiment, as Figure 1 shown, the detection module 23 includes a soil humidity detection unit 231, a light detection unit 232, a pH value detection unit 234, a fertility detection unit 235, a nitrogen fertilizer detection unit 236, a potassium fertilizer detection unit 237 and a phosphate fertilizer detection unit 238. The soil humidity detection unit mainly detects the humidity of the soil. During the growth of plants, soil humidity plays an important role. If the soil humidity is unreasonable, it will not only prevent plants from growing rapidly, but even cause plants to die due to drought or waterlogging. Therefore, in this embodiment, the soil humidity detection unit 231 is provided to improve the practicality of the soil detector of the present application.

[0031] In this embodiment, as Figure 3As shown, the soil humidity detection unit includes a detection probe 2311. The detection probe 2311 is arranged at one end of the detector main body 21. One end of the detection probe 2311 is used to be inserted into the soil, and the other end of the detection probe 2311 is electrically connected to the first control circuit board 22. That is to say, by inserting the detection probe 2311 into the soil, the detection probe 2311 can detect various data inside the soil. The first control circuit board 22 uses the detection probe 2311 to detect the soil humidity value, soil pH value, soil fertility content value, soil nitrogen fertilizer content value, soil potassium fertilizer content value, and soil phosphorus fertilizer content value. The probe in this embodiment can detect one or more of the soil humidity, soil pH value, soil fertility content value, soil nitrogen fertilizer content value, soil potassium fertilizer content value, and soil phosphorus fertilizer content value. One or more of the soil humidity data value, soil pH data value, soil fertility data value, soil nitrogen fertilizer data value, soil potassium fertilizer data value, and soil phosphorus fertilizer data value detected by the detector are transmitted to the signal receiver 32 through the signal transmitter 31. The signal receiver 32 outputs the above-mentioned detected data to the host 1. In this way, the host can receive the data detected by the detector 2 and display it on the display screen of the host. The above-mentioned soil humidity value, soil pH value, soil fertility content value, soil nitrogen fertilizer content value, soil potassium fertilizer content value, and soil phosphorus fertilizer content value can appear in the form of a percentage; the detector can detect the soil humidity, pH value, fertility, nitrogen fertilizer, potassium fertilizer, and phosphorus fertilizer through the detection probe. When the detection probe 2311 is placed in the soil, they can measure the electric charge stored in the soil. The storable electric charge is proportional to the water content in the soil. Therefore, the water content in the soil can be deduced by measuring the electric charge, and this information can be used to optimize irrigation and fertilization measures; the principle of the detection probe for detecting the soil humidity, pH value, fertility, nitrogen fertilizer, potassium fertilizer, and phosphorus fertilizer is the prior art and will not be elaborated here. In this embodiment, the soil humidity value is displayed on the host, and the soil humidity value appears in the form of a percentage. When the detection probe is not inserted into the soil, the humidity value is zero. When it is vertically inserted into the soil, it automatically measures the current soil humidity. The receiver receives the signal and displays the current humidity percentage value 41.

[0032] The soil humidity detection unit includes a detection probe 2311 and also includes a soil humidity alarm. The soil humidity alarm is arranged inside the host main body and is electrically connected to the second control circuit board. If the set default humidity value is 10%, and when it exceeds 10%, the soil humidity alarm will give an alarm. At the same time, press and hold the setting button 3 for 3 seconds to enter the humidity custom alarm value setting, and the range can be from 0% to 100%.

[0033] In this embodiment, as Figure 3As shown in the figure, one end of the detection probe 2311 for insertion into the soil is set to be conical, which is more convenient for the user to insert the detection probe 2311 into the soil. In this embodiment, it is preferably that there are two detection probes 2311. The two detection probes 2311 can detect the conductivity and pH value simultaneously, with higher precision and more accurate detection results. While one probe can only detect one index, usually the conductivity or pH value, and there are certain errors in the detection results. Therefore, two detection probes 2311 are selected in this embodiment. Whether it is two probes or one probe, the detection is of the prior art, and the detection principles of the two probes and one probe will not be elaborated here.

[0034] In this embodiment, as Figure 1 shown, the detection module 23 further includes a light detection unit 232; the light detection unit 232 mainly detects the light intensity. During the growth process of plants, light is the main energy source for plants and other organisms to survive. The light intensity and light cycle elements affect plant growth. Both the magnitude of the light intensity and the length of the light time will affect the growth cycle and physiological characteristics of plants. Therefore, the light detection unit 232 is provided in this embodiment to improve the practicability of the soil detector of this application.

[0035] The light detection unit 232 automatically measures the illuminance; the host receives the signal and displays the current illuminance value 42, referring to the comparison table.

[0036] In this embodiment, as Figure 4-5 shown, the light detection unit 232 includes a photosensitive sensor 2321. The photosensitive sensor 2321 is used to detect the ambient temperature. The photosensitive sensor 2321 is disposed in the detector main body 21 and is electrically connected to the first control circuit board 22; the photosensitive sensor is a sensitive device that responds to or converts external light signals or light radiation. The main types of photosensitive sensors are: phototubes, photomultiplier tubes, photoresistors, photosensitive triodes, solar cells, infrared sensors, ultraviolet sensors, fiber optic photoelectric sensors, color sensors, CCD and CMOS image sensors, etc. The optical sensor is one of the sensors with the largest output and the widest application. It plays a very important role in automatic control and non-electric quantity electrical measurement technology. In this embodiment, a photoresistor is preferably used. When photons strike the junction, a current will be generated. Using a photoresistor has a low production cost and can reduce the overall cost of the soil detector.

[0037] In this embodiment, as Figure 4-5As shown, the detector body 21 includes a housing 211, a base 212, and a mounting post 213. The mounting post 213 is vertically installed on the base 212. The housing 211 is sleeved on the mounting post 213, and the housing 211 is detachably covered on the base 212. The first control circuit board 22 is installed on the mounting post 213. The detector body 21 is in a long strip shape, equivalent to a grip, which is convenient for users to pick up and place the detector. The housing 211 is detachable from the base 212, which is convenient for users to open the inside of the detector body 21, facilitating users to repair the internal components of the detector and replace the storage power supply. In this embodiment, it is preferably that the mounting post 213 and the base 212 are integrally formed, which is convenient for production and reduces the installation process.

[0038] In this embodiment, as Figure 6 shown, the base 212 is provided with a first chute 2121 and a second chute 2122. Both the first chute 2121 and the second chute 2122 are arranged on the side wall of the base 212. The notch of the first chute 2121 is opened towards the mounting post 213. The first chute 2121 is communicated with the second chute 2122, and one end of the second chute 2122 is vertically arranged at the end of the first chute 2121 far from the mounting post 213. One end of the housing 211 close to the base 212 is provided with a convex block 2111. The convex block 2111 is arranged on the inner wall of the housing 211. When the housing 211 is installed on the base 212, the convex block 2111 slides from the first chute 2121 into the second chute 2122, and then the housing 211 is rotated, and the convex block 2111 is clamped in the second chute 2122. Such a clamping structure is more convenient for users to disassemble and assemble the housing, bringing convenience to users.

[0039] In this embodiment, as Figure 6 shown, the detector body 21 further includes a waterproof ring 214. An installation groove 2123 is provided in a circle on the outer side wall of one end of the base 212 where it is installed with the housing 211. The waterproof ring 214 is arranged in the installation groove 2123. When the housing 211 covers the base 212, the waterproof ring 214 is located inside the housing 211 to prevent water from entering the interface between the housing 211 and the base 212 and damaging the components of the detector body 21.

[0040] In this embodiment, the top of the housing 211 is made of a light-transmitting material, and the photosensitive sensor 2321 is arranged close to the top of the housing 211, which can better sense light and the collected data will be more accurate.

[0041] In this embodiment, as Figure 4-5 shown, the detector 2 further includes a first storage power supply 24. The first storage power supply 24 is used for storing electricity. The first storage power supply 24 is installed on the mounting post 213, reducing the installation occupancy and making the detector 2 more compact. And the first storage power supply 24 is electrically connected to the first control circuit board 22.

[0042] In this embodiment, asFigure 1 As shown, the detection module 23 further includes a temperature detection unit 233.

Since temperature has a certain impact on the growth of plants, in this embodiment, the temperature detection unit 233 is provided to improve the practicality of this application. The temperature detection unit 233 uses a temperature sensor, which is disposed inside the detector and electrically connected to the first control circuit board. The ambient temperature value 43 is displayed on the host screen.

[0043] In this embodiment, as Figure 6 shown, the signal transmitter 31 is disposed close to the top of the detector main body 21.

[0044] In this embodiment, as Figure 8 shown, a support frame 13 is provided on the back of the host main body 1. The support frame 13 can be used to support the host main body 1 on a platform, facilitating the use of the host.

There are two or more detectors 2, and two or more detectors 2 can all be wirelessly communicatively connected to the host 1. The display screen 15 can display the number of connected display detectors 2 to the host 1. The number of detectors 2 connected to the host 1 can be switched by the switching button 16, and at the same time, the corresponding detection data of the detector 2 can be switched. The setting button 17 is used to set the time and can also set the unit of the above-mentioned temperature. In this embodiment, long-press the setting button for 3 seconds to enter the time setting, select 24-hour or 12-hour, enter the minute setting, and press the setting button 3 to confirm and exit the time setting.

[0048] The specific usage method of the soil detector in this embodiment is as follows: Before use, please be sure to install the battery in the receiver for self-check (the device needs to be within 5 meters for short-distance operation), and then install the battery in the transmitter for automatic code pairing;

[0049] 1. When there are multiple transmitters: Install the battery in the receiver for self-check first, and then install the battery in each transmitter one by one for code pairing and paste a digital label sticker. This is convenient for the receiver to display that the device number is consistent with the content of the digital label sticker on the transmitter.

Install the battery in the receiver for self-check first, and then install the battery in each transmitter one by one for automatic code pairing according to the order of the digital label stickers.

[0052] Note: When the receiver and transmitter are powered on with the battery installed, they will automatically pair the code. If the code pairing order is incorrect, it will be inconvenient for management:

[0053] Method 1. The host can long-press the switching button for 10 seconds to clear (clear all display contents), and then pair the code again;

[0054] Method 2. Reorder the digital label stickers on the detector according to the numbers on the receiver side.
