Description

Technical Field

[0001] The utility model relates to the technical field of agricultural environment monitoring, in particular to an agricultural environment monitoring station. Background Art

[0002] An agricultural environmental monitoring station, a comprehensive system integrating a variety of meteorological observation instruments and equipment, plays an indispensable role in modern agricultural environmental monitoring and management. It monitors farmland's meteorological parameters and ecological indicators in real time, such as temperature, humidity, wind speed, wind direction, rainfall, and soil moisture, providing immediate and detailed environmental data support for agricultural production. This data allows personnel to quickly respond to adverse weather conditions or ecological changes, precisely manage farmland, and implement appropriate measures to ensure agricultural production safety. It also optimizes resource allocation, reduces waste, and improves agricultural production efficiency.

[0003] Traditional agricultural environmental monitoring stations include an acquisition module, a processing module, a communication module, and a power module. The acquisition module includes a variety of sensors that monitor meteorological elements in the farmland in real time. The processing module is used to receive and process the raw data from the data acquisition module. The communication module transmits the processed monitoring data to the monitoring terminal or cloud platform in real time, realizing remote access and management of the data, making it easier for staff to grasp the farmland environmental conditions at any time. The power module is used to provide power to ensure the stable operation of the remaining modules in the monitoring station.

[0004] However, over long-term operation, the data acquisition modules of traditional agricultural environmental monitoring stations are susceptible to damage, which directly leads to a significant decrease in the accuracy of the collected data. The processing modules often have difficulty promptly identifying and effectively distinguishing these abnormal signals caused by faults, which may lead to further processing and uploading these erroneous signals to the monitoring terminal or cloud platform. If staff fail to quickly detect this abnormality and take appropriate measures, the fault problem will not be resolved in a timely manner, which may not only cause unnecessary economic losses but also pose a serious threat to the stability and reliability of the entire monitoring system, affecting the overall effectiveness of agricultural environmental monitoring.

[0033] Example 1

[0034] Please refer to Figure 1-Figure 3 The utility model provides an agricultural environment monitoring station, which is the same as the existing technology, including a collection module, a processing module, a communication module, and a power module.

[0038] The power module is used to supply power to the acquisition module, processing module, and communication module to maintain the normal operation of the entire monitoring station.

[0039] Different from the existing technology, the acquisition module includes multiple groups of sensor modules, each group of sensor modules includes a main measurement module, a switching module, and a backup module; the switching module is connected to the main measurement module, the backup module, and the processing module respectively;

[0040] The switching module includes a judgment module and a control module. The judgment module, the control module, and the main measurement module are connected to each other in pairs. The signal output by the main measurement module is transmitted to the processing module through the control module.

[0041] The judgment module is used to judge whether the main test module sends an abnormal signal and send a control signal to the control module according to the judgment result;

[0042] The main measurement module is used to collect farmland environmental data in real time;

[0043] The backup module is used to replace the main measurement module in an abnormal state to collect farmland environmental data in real time;

[0044] The control module is used to start the backup module and switch the data transmission channel of the main test module to the data transmission channel of the backup module; after the channel switching is completed, the signal output by the backup module is transmitted to the processing module through the control module;

[0046] Before the channel is switched, the signal output by the main test module is sequentially transmitted to the processing module through an input terminal of the relay and an output terminal of the relay;

[0047] After the channel is switched, the signal output by the standby module is transmitted to the processing module through the second input terminal of the relay and the output terminal of the relay in sequence.

[0048] It should be explained that the sensor module includes but is not limited to a temperature sensor module, a humidity sensor module, a wind sensor module, a light intensity sensor module, and a carbon dioxide sensor module.

[0049] The main test module includes a working module 1 and a pre-judgment module, and the working module 1 and the pre-judgment module are connected;

[0050] Working module 1 is used to collect farmland environmental data in real time;

[0051] The pre-judgment module is used to judge and process the fault data of the working module one.

[0052] The pre-judgment module includes a comparator and a transistor. The positive input terminal of the comparator and the collector of the transistor are respectively connected to the working module one, the output terminal of the comparator is connected to the base of the transistor, and the emitter of the transistor is grounded; the comparator controls the conduction of the transistor according to the judgment result, and the fault data transmitted by the working module one is discharged through the transistor.

[0053] To facilitate understanding of the structure and working process of the main measuring module in the present invention, a temperature sensor module that uses a thermistor to measure temperature is taken as an example for description.

[0054] In the temperature sensor module, the main measuring module includes thermistor U1, comparator U3, transistors Q1, Q2, resistors R1, R2, R3, R4, R5, R6, R7, R8, capacitors C1, C2, C3;

[0055] Among them, the working module 1 includes thermistor U1, resistors R1, R6, R7, R8, transistor Q2, and capacitor C3; the pre-judgment module includes comparator U3, resistors R2, R3, R4, R5, capacitor C1, and transistor Q1;

[0056] Specifically, one end of the resistor R1 is connected to the power supply, and the other end of the resistor R1, one end of the resistor R2, one end of the resistor R6, the collector of the transistor Q1, and one end of the thermistor U1 are connected; the other end of the resistor R2, one end of the capacitor C1, and the positive electrode of the comparator U3 are connected, pin 5 of the comparator U3 is grounded, and pin 2 is connected to the power supply, the negative input end of the comparator U3, one end of the resistor R3, and one end of the resistor R4 are connected, the other end of the resistor R3 is connected to the power supply, and the other end of the thermistor U1, the other end of the resistor R4, and the other end of the capacitor C1 are connected and grounded. The output end of the comparator U3 is connected to one end of the resistor R5, the other end of the resistor R5, one end of the capacitor C2, and the base of the transistor Q1 are connected, the emitter of the transistor Q1, the other end of the capacitor C2, one end of the capacitor C3, and one end of the resistor R8 are connected and grounded; the other end of the capacitor C3, the other end of the resistor R6, and the base of the transistor Q2 are connected, the collector of the transistor Q2 is connected to one end of the resistor R7, and the other end of the resistor R7 is connected to the power supply; the emitter of the transistor Q2 is connected to one end of the resistor R8 and the A_OUT output end is set here.

[0057] It should be noted that the A_OUT output terminal is used to output the collected data.

[0058] The thermistor U1 may encounter two failure modes: one is a short circuit failure, that is, the internal resistance of the thermistor U1 decreases abnormally and is almost zero; the other is an open circuit failure, that is, the thermistor U1 completely loses its conductivity, the internal resistance becomes extremely large, and the current cannot pass through. Since these two failure modes manifest themselves completely differently in the circuit, the circuit designed to detect and distinguish these two failure conditions will be relatively complex. The main measurement module in the present invention can solve this problem. When the thermistor U1 is short-circuited, the base of the transistor Q2 is grounded, the transistor Q2 is cut off, and the A_OUT output terminal outputs a ground voltage; when the thermistor U1 is open-circuited, the comparator U3 judges and outputs a high level, the transistor Q1 is turned on, and the base of the transistor Q2 is grounded. At this time, the transistor Q2 is cut off, and the A_OUT output terminal outputs a ground voltage;

[0059] In both short-circuit and open-circuit conditions, the A_OUT output terminal outputs a ground voltage, allowing both fault conditions to be handled uniformly, simplifying fault detection and processing at the monitoring station.

[0060] It should be noted that the remaining sensor modules are similar to the temperature sensor module using a thermistor for temperature measurement. The difference lies in the electronic components that convert the ambient signal into an electrical signal. It is only necessary to convert the thermistor U1 of the temperature sensor module into other electronic components.

[0061] It should be explained that in order to ensure that the main measurement module can normally receive and process signals from electronic devices that measure environmental data, it is necessary to ensure that these electronic devices output analog signals.

[0062] Furthermore, the switching module includes a voltage follower U4, a comparator U5, a relay U6, a capacitor C4, and resistors R9, R10, R11, and R12;

[0063] Among them, the judgment module includes a voltage follower U4, a comparator U5, a capacitor C4, and resistors R9, R10, and R11; the control module includes a relay U6 and a resistor R12;

Pin 1 of the relay U6 is connected to the resistor R12 and the B_OUT output is set here. The other end of the resistor R12 is grounded.

[0065] It should be noted that the model of relay U6 is SRD-24VDC-SL-C.

[0066] It should be noted that the B_IN1 input terminal is connected to the A_OUT output terminal, and the OUT output terminal is connected to the processing module; the B_IN2 input terminal and the B_OUT output terminal are respectively connected to the backup module.

[0067] The data collected by the main measuring module is transmitted to the processing module in turn through the B_IN1 input terminal, relay U6, and OUT output terminal, and the judgment module judges in real time whether the data collected by the main measuring module is fault data; when the judgment module judges that the main measuring module is fault data, the judgment module outputs a control signal to relay U6, relay U6 switches the transmission channel, and outputs a control signal from the B_OUT output terminal to the backup module to start the backup module; the data collected by the backup module is transmitted to the processing module in turn through the B_IN2 input terminal, relay U6, and OUT output terminal, ensuring the continuity of data collection.

[0068] The standby module includes a second working module and an alarm module. The second working module transmits an alarm signal to the processing module through the alarm module. The control end and the output end of the second working module are respectively connected to the switching module.

[0074] It should be noted that the C_IN input terminal is connected to the B_OUT output terminal, the C_OUT2 output terminal is connected to the B_IN2 input terminal; and the C_OUT1 output terminal is connected to the processing module.
