[0025] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.
[0026] As shown in Figure 6, there are alarm 1, meter 2, self-resetting sensor 3, controller 4, and granary 5;
[0027] An intelligent grain full alarm system, comprising:
[0028] Self-resetting sensor 3: connected to the controller 4 signal, when the grain is full, it sends a low-level signal to the controller 4;
[0029] Alarm 1: connected to the controller 4 via a power supply, used to issue an alarm;
[0030] Power supply: controlled by the controller 4, used to output current to the alarm 1;
[0031] Threshing clutch motor: It is provided with a separation button and a combination button. The separation button is used to control the machine to stop working and send a separation signal to the controller 4. After receiving the separation signal, the controller 4 controls the power supply to stop outputting current to the alarm 1. The combination button is used to control the machine to continue working and send a combination signal to the controller 4. When the controller 4 receives the combination signal and the low-level signal at the same time, it controls the power supply to output current to the alarm 1;
[0032] Controller 4: used to receive signals from various components and send signals. It is connected to the instrument 2 through CAN protocol transmission. It is used to check the circuit status and transmit circuit problems to the instrument 2 through signals.
[0033] Instrument 2: used to receive circuit status information and report errors to staff.
[0034] Specifically, the self-resetting sensor 3 is located in the granary 5. When the grain is full, the sensor sends a low-level signal to the controller 4. After receiving the low-level signal, the controller 4 controls the power supply to output current to the alarm 1 to make it alarm. The threshing clutch motor is provided with a separation button and a combination button. The separation button is used to control the machine to stop working and send a separation signal to the controller 4. After receiving the separation signal, the controller 4 controls the power supply to stop outputting current to the alarm 1. The combination button is used to control the machine to continue working and send a combination signal to the controller 4. When the controller 4 receives the combination signal and the low-level signal at the same time, it controls the power supply to output current to the alarm 1. The controller 4 checks the real-time status of the circuit and sends the information to the instrument 2. The instrument 2 is used for personnel to check the circuit status and issue an alarm when there is a problem with the circuit.
[0035] In this embodiment, the alarm 1 is an audible and visual alarm 1, comprising:
[0036] Sound generator: This is the core part of the sound and light alarm 1, used to generate the alarm sound. The sound generator is usually a buzzer or speaker that can produce high-decibel sounds;
[0037] Light signal generator: A light signal generator produces a visual alarm, typically one or more LED lights or a flashing light. These lights can be red, yellow, blue, or other eye-catching colors to ensure they can be seen in a variety of environments.
[0038] Control Unit: The control unit is the brain of the audible and visual alarm 1, responsible for receiving the trigger signal and controlling the generation of the sound and light signals. It may contain a microcontroller 4 or other electronic components to process the input signals and drive the alarm.
[0039] Trigger mechanism: A trigger mechanism can be any sensor or switch that detects an emergency and sends a signal to the control unit. For example, in a fire alarm system, a smoke detector or temperature sensor can act as a trigger mechanism.
[0040] Power supply: The sound and light alarm 1 requires a power source to operate. This may be AC power, DC power or batteries.
[0041] Enclosure: The enclosure protects internal components from physical damage and ensures that sound and light can travel effectively. Enclosures are typically made of plastic, metal, or other durable materials.
[0042] Mounting bracket: To facilitate installation, the sound and light alarm 1 is usually equipped with a mounting bracket that can be fixed to a wall, ceiling or pillar.
[0043] In this embodiment, the self-resetting sensor 3 is a proximity switch.
[0044] The proximity switch includes the following structures:
[0045] Sensor head: This is the main part of the proximity switch, containing the electronics and circuitry used to detect objects. It is usually made of plastic or metal to protect the internal components.
[0046] Sensing element: The sensing element is the core of the proximity switch, which can be inductive, capacitive, photoelectric or ultrasonic, etc. Different types of sensing elements are suitable for different detection objects and environments.
[0047] Inductive: Detects metal objects through the principle of electromagnetic induction.
[0048] Capacitive: Detects objects through changes in capacitance and is suitable for non-metallic objects.
[0049] Photoelectric type: uses the photoelectric effect to detect objects and can detect transparent objects.
[0050] Ultrasonic: Detects objects by emitting and receiving ultrasonic waves.
[0051] Signal processing circuit: This part of the circuit is responsible for processing the signal collected by the sensing element and converting it into a switching signal that can be used for control logic.
[0052] Output module: The output module converts the processed signal into a switching signal, such as an on / off state or a digital signal, which is used to control other devices or provide status feedback.
[0053] Instructions for use:
[0054] When the granary 5 is just full, the sensor sends a low-level signal to the controller 4. The controller 4 controls the power supply to provide voltage to the alarm 1, so that the alarm 1 works and sends the information that the granary 5 is full to the meter 2. After the personnel know this, they press the separation button, the working mechanism of the agricultural machinery stops working, and the motor sends a separation signal at the same time. The alarm 1 stops alarming, but the low-level signal is still there.
[0055] If the staff forgets to unload the grain and continues to operate the agricultural machine and presses the engagement button, the working mechanism will work and the motor will send out an engagement signal. The controller 4 will receive the low-level signal and the engagement signal from the sensor at the same time and will continue to control the alarm 1 to sound an alarm to remind the staff to unload the grain.
[0056] The controller 4 will detect the power output status of the sound and light alarm 1 in real time, and send a message to the meter 2 when a short circuit or open circuit occurs to prompt the user whether there is a short circuit or open circuit.
[0057] After unloading the grain, the controller 4 does not detect the low-level signal of the grain full sensor. Regardless of whether the threshing clutch motor is in the engaged or disengaged state, the controller 4 will no longer output voltage to the sound and light alarm 1, nor will it send a full message to the meter 2. However, the controller 4 will send the line status of the grain full alarm system to the meter 2 in real time.
[0058] Instrument 2 monitors the working status of the grain full alarm system in real time through detection messages.
[0059] When the sensor self-reset switch fails and cannot be reset automatically, after unloading the grain, when the combination key is pressed, the alarm 1 will continue to alarm to remind personnel of the sensor failure.
[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
