Embodiment 1
[0045] The embodiment of the present invention proposes a method for monitoring precision corn seeding operations, see figure 2 , the method includes performing the following steps in the monitoring device:
[0046]Step 201: Start the monitoring device and enter the user setting interface, where the user sets operation parameters, and enters the monitoring interface after confirmation by the user.
[0047] The operating parameters specifically include: single grain weight, alarm interval, number of monitoring rows, upper threshold, lower threshold, sowing width, cycle interval, number of magnets and circumference of the ground wheel. All job parameters are set with default values (e.g. figure 1 shown) to ensure the normal operation of the monitoring device, when the user sets the operating parameters, the operating parameters are updated from the default value to the set value set by the user.
[0048] After the setting is completed, the user interface is transferred to t...
Embodiment 2
[0090] The embodiment of the present invention proposes a device for monitoring the precise sowing operation of corn, and the device includes:
[0091] A seven-inch LCD touch screen and a set of buttons are used to output operation status parameters to the user, and can also be used for the user to input operation parameters. For the user interface, see figure 1 , Figure 4 and Figure 5 .
[0092] The six-way infrared photoelectric sensor is used to obtain the information of the number of seeds sown in the six-row seed delivery tube.
[0093] The six-way input capture circuit is used to process and collect signals from the sowing monitoring sensor indicating the number of sowing grains of the six rows of seeding pipes, and output them to the microprocessor.
[0094] One ground wheel speed sensor is used to obtain information representing the ground wheel speed.
[0095] One external interrupt circuit is used to process and collect the signal representing the ground wheel ...

Abstract
The invention relates to the field of agricultural engineering, and particularly relates to a device and a method for monitoring corn precision seeding operation. The device particularly comprises a microprocessor, input and output devices facing users, an infrared photoelectric sensor, a signal acquisition circuit and an alarm device. The method particularly comprises that: after operation parameters are set by the users on a setting interface, an operation monitoring scanning cycle is started; a signal indicating the state of seeding operation is firstly acquired, then the signal indicating the state of seeding operation is computed with combination of the operation parameters so that parameters indicating the state of seeding operation are obtained and outputted and displayed to the users in real time; then whether the seeding state is normal is judged via the operation state parameters, and alarm is performed to the users if the seeding state is abnormal through judgment; and finally the scanning monitoring process is repeated via returning to the operation monitoring scanning cycle till the users terminate. Seeding grain numbers in corn precision seeding operation are monitored in real time by the device and the method, and great fault alarm sensitivity is achieved.
Description
technical field [0001] The invention relates to the field of agricultural engineering, in particular to a device and method for monitoring precision sowing operations of corn. Background technique [0002] Maize mechanical precision seeding technology is a kind of agricultural mechanization that selects high-quality seeds, creates good seed beds, and makes the row spacing, plant spacing, and sowing depth of seeds planted into the soil meet the agronomic requirements, and the depth of covering soil is consistent. Practical technology. Corn precision seeding monitoring technology is an important part of modern corn precision seeder, its performance will directly affect the quality of precision seeding. Since the seed flow process of the corn planter is completely closed during sowing, it is almost impossible to directly monitor the quality of its operation by human audiovisual alone, such as the emptying of the seed box, the blockage of the seed delivery pipe, and the seed me...
