It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1, as an example of the present application, a soil parameter monitoring system based on mobile network communication includes: soil parameter monitoring devices, monitoring server and terminal equipment.

Wherein, soil parameter monitoring devices are used for burying in order to detect the parameter of soil in order to detect soil completely in soil, for example the water content of soil, temperature etc.. Specifically, the soil parameter monitoring device has a built-in power supply and a wireless communication module so that the soil parameter monitoring device can be freely buried without being tied by cables.

The monitoring server is used for processing and storing the detection data of the soil parameter monitoring device, for example, storing the detection data according to the acquisition time, or matching the detection data with the soil parameter monitoring device, or matching the detection data with the geographic position of the soil parameter monitoring device.

The terminal equipment is used for at least displaying the detection data of the soil parameter device to a user. More specifically, the terminal device provides a human-computer interaction interface for a user, so that the user can acquire required data or perform corresponding operations. As a preferred solution, the terminal device may be a mobile terminal device, such as a smart phone or a tablet computer; in some professional fields, the terminal device may also be a non-mobile terminal, such as a computer device or a workstation device with an interactive function. It should be noted here that, when the monitoring server has or is connected with a human-computer interaction device, it may also be used as a device for a user to interact with the soil parameter monitoring system based on mobile network communication.

As a specific scheme, the soil parameter monitoring device and the monitoring server form wireless communication connection so that the soil parameter monitoring device transmits data to the monitoring server through at least one first-class network. The first type of network is a wireless network in which the soil parameter monitoring device can transmit data, the communication module of the soil parameter monitoring device enables the soil parameter monitoring device and the soil parameter monitoring device to transmit data through the first type of network, and the transmitted data internally comprises detection data related to soil parameters and equipment data related to equipment, such as equipment electric quantity, equipment position and the like.

In addition, the monitoring server and the terminal device form a communication connection so that the monitoring server transmits data to the terminal device through at least one second type network different from the first type network.

The first type network and the second type network have difference in data transmission rate, and the transmission rate of the first type network is far smaller than that of the second type network; meanwhile, the power required by the first type of network for transmitting data is much smaller than that required by the second type of network for transmitting data.

As a specific scheme, the ratio of the transmission rate of the second type network to the transmission rate of the first type network ranges from 800 to 9375.

As a more specific solution, the first type of network is a Low Power Wide Area Network (LPWAN) with a transmission rate ranging from 0.3kbps to 500 kbps; further, the transmission rate ranges from 100kbps to 300 kbps.

The first kind of network is a network constructed by one or more of NB-IoT, LoRa, Sigfox and eMTC. As a preferred scheme of the present application, the first type of network is an NB-IoT network, and the transmission output rate thereof ranges from 160kbps to 250 kbps.

As a specific scheme, the second type of network is a 3G, 4G or 5G mobile communication network, or other wired network. The ratio of the transmission rate of the second type of network to the transmission rate of the first type of network ranges from 800 to 9375.

By adopting the scheme, different requirements of the data acquisition end and the user end can be considered. At the acquisition end, soil parameters generally do not change drastically, and the embedded equipment is required to acquire data for a long time, namely, the requirement on sampling frequency is not high, and the time for acquiring the data continuously is high. At the user end, the value of single-point or single-moment soil parameters is not great for professional users, and the professional users often need a plurality of soil parameter monitoring devices to analyze and research data in a long time period so as to make a prejudgment or improvement measure, so that the professional users often need the terminal equipment to acquire a large amount of required parameter data and equipment data in a short time when using the terminal equipment. The first-type network and the second-type network are different networks in formal requirements, and the ratio of the transmission rates of the first-type network and the second-type network needs to be kept within a certain preset range in consideration of the practical situation of soil parameter research, so that different requirements of the acquisition end and the user end can be met.

As a further scheme, in order to set up a system more conveniently, the soil parameter monitoring system based on mobile network communication further comprises: a network server. The network server is used for transmitting data between the soil parameter monitoring device and the monitoring server; the network server and the monitoring server form communication connection through a third type network. The network server is a server of an operator or other third parties, the network server is used as a relay server of a first-class network established by the operator, and as long as the soil parameter monitoring device can be accessed to the first-class network, the soil parameter monitoring device and the network server can transmit data to the network server, and then the network server transmits the data to a server of an application-level user according to setting and a protocol, namely the monitoring server in the application. A plurality of soil parameter monitoring devices are connected to a network server in a communication mode.

As a specific scheme, the first type of network adopts NB-IoT, each soil parameter monitoring device can be added to the NB-IoT network provided by an operator through an NB-IoT module of the first type of network, and a server of the operator is used as a network server in the application to perform data transmission with the soil parameter monitoring devices through the NB-IoT network.

As a specific solution, the third type network between the network server and the monitoring server may be a wired network or a wireless network, and as an alternative, the transmission rate of the third type network is greater than or equal to the transmission rate of the second type network.

Referring to fig. 2, as an extended scheme, the soil parameter monitoring device is divided into: a terminal soil parameter monitoring device and a transfer soil parameter monitoring device; the terminal soil parameter monitoring device and the transfer soil parameter monitoring device form wireless communication connection to transmit data; the transfer soil parameter monitoring device and the monitoring server form wireless communication connection so that the transfer soil parameter monitoring device transmits detection data of the terminal soil parameter monitoring device to the monitoring server.

More specifically, in an area without coverage of, for example, an NB-IoT network, in order to enable the soil parameter monitoring device to perform data interaction with the monitoring server through a wireless network, a transit soil parameter monitoring device may be provided, which has a function of a general terminal soil parameter monitoring device, and also has a function of networking with other terminal soil parameter monitoring devices, for example, networking is performed by using a short-range network, for example, networking is performed by using a ZigBee network, so that each terminal soil parameter monitoring device can transmit data to the transit soil parameter monitoring device (of course, data may also be transmitted in a reverse direction), and the transit soil parameter monitoring device is further provided with an outgoing communication module, which can transmit data through another network or signal. For example, the transit soil parameter monitoring device may transmit data through the satellite communication system, and then transmit the data to the monitoring server through the data service of the satellite communication system. As an extension scheme, compared with a general terminal soil parameter monitoring device, the transit soil parameter monitoring device has a battery with a larger capacity and an additional antenna device. When the device is buried, the device for monitoring the parameters of the transferred soil can also be buried in shallow soil.

Referring to fig. 3 to 25, as an example of controlling a terminal and a control function of the soil parameter monitoring device of the present application, fig. 3 to 25 show a control scheme based on a mobile terminal and a wechat applet, and the functions of the soil parameter monitoring system of the present application will be described with reference to the example.

Wherein, the alarm content comprises the equipment number and the detection result of the water content; the alarm occurrence time displays the year, month, day and specific time point of the alarm occurrence; the remarks mainly reflect the problems corresponding to the alarm and measures against the problems. Buttons for "find new details" which can be clicked to open the device integrity data, and "item" for opening further options or menus are also provided in the interface.

Based on the above interface, the soil parameter monitoring system based on mobile network communication of the application has the following functions: and setting a water content threshold range, and sending alarm notification data to the terminal equipment when the monitoring server judges that the water content data uploaded by the soil parameter monitoring device exceeds the water content threshold range. As an extension scheme, soil parameter monitoring devices can detect temperature data to upload temperature data to monitoring server, when temperature data surpassed the threshold value scope, carried out temperature alarm equally, introduced technical scheme promptly in this application, the function that is applicable to the water content is applicable to temperature data's detection and processing equally.

After clicking the "item" button in fig. 3, the further displayed interface is shown in fig. 4, and as shown in fig. 4, the bottom of the interface provides four function buttons: group management, my device, add device, and settings.

Specifically, the device name may be named by the user for user identification, which may be named in chinese or english, and the serial number is a unique identification ID of the device for use in the monitoring server as unique identification information of the soil parameter monitoring device. The administrator has a corresponding administrative member for the device. The carrier and ICCID display the device network operation message. The temperature normality interval corresponds to the previously stated moisture content threshold range, and the moisture content threshold range and the humidity normality interval are equivalent concepts in the present application.

The working mode is a mode and frequency for setting the soil parameter monitoring equipment to detect and upload data, and the working mode can be set, and particularly, the working mode can comprise two aspects, whether the time for measuring and uploading the data is synchronous or not, and the frequency of the respective actions. As a specific example, the mode in fig. 14 is "synchronous transmission and transmission measurement every 1 day", and it can be set to asynchronous transmission and transmission measurement, 6 am: 00 for detection, and uploading data at 12:00 noon or 0:00 early morning. The frequency of the test transmission can adopt 2 times per day or one test transmission every 2 days.

The sensor body 101 includes a housing and an internal structure thereof. The probes 102 are three in number and may be arranged side-by-side in parallel, with one probe being used to transmit electromagnetic signals and the other probe being used to receive electromagnetic signals. The circuit and the chip in the sensor body 101 calculate the change of the dielectric constant to obtain a soil parameter, such as the humidity of the soil, when the electromagnetic signal propagates, and the measurement can be performed by adopting the principle of FDR or TDR.

Thus, the sensor body 201 can be inserted after a hole is drilled without digging a pit and burying, and the solar cell panel 203 can be arranged as an electric energy source when a certain shallow layer is detected or one end of the sensor body 201 is exposed due to the size of the sensor body 201. This can further increase the time of use, but the exposed portion may affect agricultural cultivation to some extent.

As shown in fig. 29, the soil parameter monitoring device of the present application includes: the device comprises an electrode module, a signal module, a main control module, a communication module, a power supply module and an interaction module.

The electrode module comprises a plurality of electrodes, and the electrodes are used for connecting with an internal circuit to transmit or receive electromagnetic signals. Preferably, the electrode may be configured as a probe as shown in fig. 27, or as a ring electrode as shown in fig. 28, or in other configurations such as a U-shape.

Wherein, the signal module is used for producing and handling the required signal of soil parameter detection, and specifically, the signal module can include: signal source circuit and detection circuitry. The signal source circuit can generate electromagnetic pulse signals with certain frequency (50MHz to 100MHz, preferably 75MHz) under the control of the main control module, and the electromagnetic pulse signals are conducted to one electrode through a coaxial cable or other conductive connection. The detection circuit is also conducted to one electrode in a similar way, namely a coaxial cable or other conductive connection is adopted, the electrode can receive an electromagnetic signal sent by the other electrode, and the electromagnetic signal conducted by the electrode is detected and converted by the detection circuit to become a digital signal which can be processed by the main control module.

The main control module is mainly used for performing control functions such as signal processing and the like, and can comprise a processor and a memory. The processor and the memory may be formed by separate chips or may be formed by an integrated chip and corresponding peripheral circuits. The main control module can also realize the control of other modules, and the control can be set based on the program of the main control module, and can also be triggered by signals or data fed back by other modules.

As an extension, the NB-IoT-based soil parameter monitoring device comprises a thermistor for generating a corresponding temperature detection signal according to the temperature; the thermistor is electrically connected with the main control module. Along with the temperature change, the electrical parameters of the thermistor change, so that different electric signals are generated, and the main control module can acquire temperature data according to the electric signals. Alternatively, the thermistor is a PTC element or an NTC element.

The communication module comprises a communication module to realize data interaction between the main control module and the outside, and specifically, the communication module comprises an NB-IoT chip, so that the main control module can communicate through an NB-IoT network. More specifically, the communication module further includes an eSIM card and an antenna device, which are electrically connected to each other. Wherein the antenna device comprises a PIFA antenna.

The interaction module is used for the user to operate or feed back information to the user; the interactive module comprises a button device and a display device. The button device is used for being operated by a user to switch on and off and switch modes, and the display device is used for displaying a working mode or/and an electric quantity state.

The power module at least comprises a lithium ion battery, the power module is mainly used for providing electric energy required by each module, and the power module can be directly connected to each module to supply power for the modules or indirectly supply power for each module through the main control module.

As one of the schemes, the power module directly supplies power to the signal source circuit in the signal module, and the control module is electrically connected to the semiconductor device in the signal source circuit to control the generated electromagnetic wave signal, where the signal source circuit is equivalent to a pulse discharge circuit of the power module. The power module also directly supplies power for the control module, and then the control module supplies power for the communication module or/and the interaction module. The power module outputs a difference to the signal source circuit and the main control module, specifically, the voltage output to the signal source circuit by the power module is less than or equal to the voltage output to the signal source circuit by the power module; more specifically, the output voltage of the positive pole of the first power supply is less than or equal to the output voltage of the positive pole of the second power supply.

As a specific scheme, the power module adopts a lithium thionyl chloride battery and a super capacitor. The power module further comprises a series element, and the series element is connected with the super capacitor in series and then connected with the lithium ion battery in parallel.

As shown in the scheme of fig. 30, the series element is a resistor, and when the scheme is adopted, the positive electrode of the battery is used as the positive electrode of the second power supply and is electrically connected to the main control module (or the communication module), and the positive electrode of the capacitor is used as the positive electrode of the first power supply and is electrically connected to the signal source circuit of the signal module.

As shown in the scheme of fig. 31, when the series element is a diode, in this scheme, the positive electrode of the battery is used as the positive electrode of the first power supply and is electrically connected to the signal source circuit of the signal module, and the positive electrode of the capacitor is used as the positive electrode of the second power supply and is electrically connected to the main control module (or the communication module).

Alternatively, instead of using a series element, a lithium ion battery may be directly connected in parallel with a super capacitor, and only one voltage may be output.

The soil parameter monitoring device of this application to do not adopt any external cable, consequently, in order to realize long-time work, on the basis of not considering to trade the electricity and charge, need to have a battery that can supply power for a long time. Therefore, the lithium thionyl chloride battery is selected as the battery with the highest specific energy in the practical battery series, and the specific energy can reach 590 W.h/kg and 1100 W.h/L. While it has a relatively low discharge rate. However, the lithium thionyl chloride battery has the corresponding disadvantages that it is not a rechargeable battery at first, and in addition, the discharge rate is low (the annual self-discharge rate is very small, the energy type is less than 1%, and the power type is less than 2%) because when metal lithium reacts with thionyl chloride, oxidation products are generated, metal lithium is attached to the oxidation products, namely, an oxide film is generated, and the oxidation film protects the metal lithium at the negative electrode, so that the continuation of the chemical reaction, namely, self-discharge is prevented. However, the internal stop reaction is only relative, and the increase of the thickness of the oxide film can cause the increase of the internal resistance of the battery, thereby generating a voltage hysteresis phenomenon, and the voltage hysteresis influences the voltage-based functions of a load circuit and a control circuit.

As another design problem in the design of the present application, the NB-IoT chip is a low-power communication chip, which is also the basis for the soil parameter monitoring device of the present application to work for a long time and has low energy consumption; the soil parameter monitoring device of the application is based on emitting high-frequency electromagnetic waves, the energy consumption is relatively high, in a general application scene, the NB-IoT chip can emit a set of effective data only after multiple detections (emitting electromagnetic waves), that is, the detections are greater than the data transmission in the use frequency. In the scheme of this application, the operating current when detecting is 25mA, and standby current is 0.006mA, and it is big to see two kinds of discharge state differences, and lithium thionyl chloride battery is the battery that can not charge, if directly adopt this type of battery to directly carry out the constant value and discharge, then can't realize the electric energy of overflowing and recycle, adopt the effect of NB-IoT chip to discount greatly.

In view of above principle and actual conditions, the scheme that introduces before the power module of this application adopts a super capacitor and lithium thionyl chloride battery collocation scheme, makes super capacitor can overcome and cause the extravagant phenomenon of electric energy because lithium thionyl chloride battery characteristic, simultaneously, cohesion soil parameter monitoring devices detects characteristics itself again, makes lithium thionyl chloride battery eliminate the influence that the voltage that partial oxide film brought through pulse discharge lags, and super capacitor can provide comparatively stable and accurate voltage source for control module again simultaneously.

As shown in fig. 30, the lithium thionyl chloride battery charges the super capacitor through the diode until the super capacitor is equipotential, the super capacitor provides a voltage for the main control module due to the existence of the diode, that is, the voltage after the lithium thionyl chloride battery discharges last time, and the positive electrode of the lithium thionyl chloride battery is directly connected with the signal source circuit, that is, a pulse discharge circuit, when the signal source circuit works, the pulse discharge circuit can eliminate the oxide film of the lithium thionyl chloride battery and reduce the internal resistance of the lithium thionyl chloride battery, and the super capacitor is continuously charged when the internal resistance of the lithium thionyl chloride battery is high, so that the electric energy is not wasted, and meanwhile, the energy for eliminating the oxide film can be recharged into the super capacitor after the internal resistance becomes high again. Each electric energy discharged from the lithium thionyl chloride battery is maximally utilized.

As an extension, as shown in fig. 32, the diode may be replaced by a controllable semiconductor element such as a field effect transistor, and the control terminal of the diode may be controlled by the main control module, so as to more intelligently control the power distribution of the power module.

As shown in fig. 31, due to the existence of the resistor, when the signal source circuit is pulsed to discharge, the electric energy in the super capacitor is used first, and since the pulse discharge affects the lithium thionyl chloride battery at the same time, the internal resistance thereof is reduced, and the voltage is reduced to a real level, the electric energy stored in the super capacitor due to the increase of the internal resistance is used for the signal source circuit and also used for removing the oxide film.

In conclusion, the soil parameter monitoring device overcomes the technical problems caused by directly adopting the lithium thionyl chloride battery and the NB-IoT module to be directly used for the soil parameter monitoring device, particularly the FDR-based soil humidity sensor, and provides the soil parameter monitoring device comprehensively considering the problems of detection, communication and energy consumption.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
