[0055] A counting method of a photoelectric seed sensor provided in an embodiment of the present application is described in detail below.
[0056] Reference Figure 1 As shown, it is a flow chart of a counting method of a photoelectric seed sensor provided in an embodiment of the present application. The specific execution process of the counting method of the photoelectric seed sensor is as follows:
[0057] S101, obtaining a reference threshold voltage and a latest pulse width reference range corresponding to a target seed type, and a voltage signal corresponding to the target seed type currently collected by a photoelectric seed sensor.
[0058] S102: Determine whether the voltage peak value of the pulse in the voltage signal is greater than or equal to a reference threshold voltage.
[0059] S103 . If the voltage peak value of the pulse in the voltage signal is greater than or equal to the reference threshold voltage, determine whether the pulse width of the pulse whose voltage value is greater than or equal to the reference threshold voltage is within a pulse width reference range.
[0060] S104: If the pulse width in which the voltage value in the pulse is greater than or equal to the reference threshold voltage is within the pulse width reference range, the number of seeds corresponding to the target seed type is increased by one.
[0061] The embodiment of the present application provides a counting method of a photoelectric seed sensor, which obtains a reference threshold voltage and the latest pulse width reference range corresponding to the target seed type, as well as a voltage signal corresponding to the target seed type currently collected by the photoelectric seed sensor; determines whether the voltage peak of the pulse in the voltage signal is greater than or equal to the reference threshold voltage; if the voltage peak of the pulse in the voltage signal is greater than or equal to the reference threshold voltage, determines whether the pulse width of the pulse whose voltage value is greater than or equal to the reference threshold voltage is within the pulse width reference range; if the pulse width of the pulse whose voltage value is greater than or equal to the reference threshold voltage is within the pulse width reference range, the number of seeds corresponding to the target seed type is increased by one. The present application counts various types of seeds by referring to the threshold voltage and the pulse width reference range, thereby improving the counting accuracy of small-grain seeds.
[0062] The following is a description of the exemplary steps of the present application embodiment:
[0063] S101, obtaining a reference threshold voltage and a latest pulse width reference range corresponding to a target seed type, and a voltage signal corresponding to the target seed type currently collected by a photoelectric seed sensor.
[0064] In the implementation mode of the present application, the target seed type refers to the seed type that the photoelectric seed sensor is currently counting, which may be sorghum, corn, etc. When the seed passes through the detection area of the photoelectric seed sensor, it will cause a change in the detection voltage, and the photoelectric seed sensor will collect the voltage signal of the seed corresponding to the target seed type. And set the corresponding reference threshold voltage and the latest pulse width reference range for the target seed type to determine whether the pulse in the voltage signal is caused by the seed corresponding to the target seed type, or by impurities other than the seed (such as stones, dust, etc.). One or more pulses may be included in a voltage signal within a period of time.
[0065] The pulse width reference range is updated based on the target pulse widths of the target seeds corresponding to the target seed type and the preset number of the most recently collected ones; the pulse width reference range includes a maximum pulse width reference value and a minimum pulse width reference value.
[0066] Furthermore, before counting the seeds corresponding to the target seed type by the photoelectric seed sensor, the reference threshold voltage corresponding to the target seed type is determined by the following steps:
[0067] Step 1: Obtain the voltage signal of the sample seed corresponding to the target seed type collected by the oscilloscope.
[0068] In the implementation mode of the present application, an oscilloscope is a widely used electronic measuring instrument, which can transform invisible electrical signals into visible images, making it easier for people to study the changing process of various electrical phenomena. The voltage signal of the sample seed corresponding to the target seed type is collected by the oscilloscope, and the sample seed refers to the seed used to determine the reference threshold voltage corresponding to the target seed type.
[0069] For example, if the target seed type is sorghum, the voltage signals of multiple sample sorghum seeds are collected through an oscilloscope.
[0070] Step 2: Determine the reference threshold voltage according to the voltage peak values of all pulses in the voltage signals of all sample seeds.
[0071] In an embodiment of the present application, the average value of the voltage peaks of all pulses in the voltage signals of all sample seeds can be determined as the reference threshold voltage; the minimum value of the voltage peaks of all pulses in the voltage signals of all sample seeds can be determined as the reference threshold voltage.
[0072] Furthermore, before counting the seeds corresponding to the target seed type by the photoelectric seed sensor, the method further includes:
[0073] Step 1: Determine the maximum value of the pulse widths whose voltage values in all pulses in the voltage signals of all sample seeds are greater than or equal to the reference threshold voltage as the maximum pulse width reference value in the first pulse width reference range.
[0074] In an embodiment of the present application, a pulse includes a rising edge and a falling edge. The time point at which the voltage value in the falling edge is the reference threshold voltage is subtracted from the time point at which the voltage value in the rising edge is the reference threshold voltage to obtain the pulse width when the voltage value in the pulse is greater than or equal to the reference threshold voltage.
[0075] Reference Figure 2 As shown, it is a schematic diagram of the voltage signal provided in an embodiment of the present application; in this figure, the pulse width of the first pulse can be obtained by subtracting time point 1 from time 2.
[0076] Step 2: Determine the minimum value of the pulse width whose voltage value is greater than or equal to the reference threshold voltage among all pulses in the voltage signals of all sample seeds as the minimum reference value of the pulse width in the first pulse width reference range.
[0077] Furthermore, the pulse width reference range is updated by the following steps:
[0078] Step 1: Obtain the target pulse widths of the latest collected preset number of target seeds corresponding to the target seed type.
[0079] In the embodiment of the present application, when the number of seeds corresponding to the target seed type increases by a preset number, the target pulse width of the preset number of target seeds corresponding to the target seed type collected the most recently is obtained. The target pulse width refers to the pulse width of the voltage value in the pulse caused by the target seed being greater than or equal to the reference threshold voltage.
[0080] The target pulse width of the target seed is obtained by subtracting the time point when the voltage value of the falling edge of the pulse caused by the target seed is the reference threshold voltage from the time point when the voltage value of the rising edge of the pulse caused by the target seed is the reference threshold voltage.
[0081] Step 2: updating the maximum pulse width reference value or the minimum pulse width reference value according to the first difference between each target pulse width and the maximum pulse width reference value and the second difference between each target pulse width and the minimum pulse width reference value.
[0082] In an embodiment of the present application, the number of target pulse widths whose first difference is less than the second difference is counted to obtain a first number; the number of target pulse widths whose first difference is greater than the second difference is counted to obtain a second number; and based on the numerical relationship between the first number and the second number, the maximum reference value of the pulse width or the minimum reference value of the pulse width is updated based on all target pulse widths.
[0083] The first difference is obtained by subtracting the absolute value of the difference between the target pulse width and the maximum reference value of the pulse width, and the second difference is obtained by subtracting the absolute value of the difference between the target pulse width and the minimum reference value of the pulse width.
[0084] For example, if the target pulse width is 5 s and the maximum pulse width reference value is 8 s, then the first difference between the target pulse width and the maximum pulse width reference value is |5-8|=3 s.
[0085] Specifically, if the first number is greater than the second number, the pulse width maximum reference value is updated according to all target pulse widths whose first difference is less than the second difference.
[0086] In the embodiment of the present application, if the first number is greater than the second number, it means that there are more target pulse widths closer to the maximum reference value of the pulse width, so the maximum reference value of the pulse width is updated. The average value of all target pulse widths whose first difference is less than the second difference can be determined as the updated maximum reference value of the pulse width. It is also possible to perform a weighted summation on all target pulse widths whose first difference is less than the second difference to obtain the updated maximum reference value of the pulse width.
[0087] Specifically, if the first number is smaller than the second number, the minimum pulse width reference value is updated according to all target pulse widths whose first difference is larger than the second difference.
[0088] In the embodiment of the present application, if the first number is less than the second number, it means that there are more target pulse widths closer to the minimum reference value of the pulse width, so the minimum reference value of the pulse width is updated. The average value of all target pulse widths whose first difference is greater than the second difference can be determined as the updated minimum reference value of the pulse width. It is also possible to perform a weighted summation on all target pulse widths whose first difference is greater than the second difference to obtain the updated minimum reference value of the pulse width.
[0089] S102: Determine whether the voltage peak value of the pulse in the voltage signal is greater than or equal to a reference threshold voltage.
[0090] In the embodiment of the present application, whether the voltage signal is caused by a seed is determined by judging whether the voltage peak value of the pulse in the voltage signal is greater than or equal to the reference threshold voltage. For each pulse in each voltage signal, it is judged whether the voltage peak value of the pulse in the voltage signal is greater than or equal to the reference threshold voltage.
[0091] S103 . If the voltage peak value of the pulse in the voltage signal is greater than or equal to the reference threshold voltage, determine whether the pulse width of the pulse whose voltage value is greater than or equal to the reference threshold voltage is within a pulse width reference range.
[0092] In an embodiment of the present application, if the voltage peak value of the pulse in the voltage signal is greater than or equal to the reference threshold voltage, it means that the voltage signal may be caused by a seed, so it is further determined whether the pulse width of the pulse whose voltage value is greater than or equal to the reference threshold voltage is within the pulse width reference range.
[0093] S104: If the pulse width in which the voltage value in the pulse is greater than or equal to the reference threshold voltage is within the pulse width reference range, the number of seeds corresponding to the target seed type is increased by one.
[0094] In an embodiment of the present application, if the pulse width of the pulse whose voltage value is greater than or equal to the reference threshold voltage is within the pulse width reference range, it means that the voltage signal is caused by the seed, so the number of seeds corresponding to the target seed type is increased by one.
[0095] Reference Figure 3 As shown, it is a flow chart of a counting method of a photoelectric seed sensor provided in an embodiment of the present application. The exemplary steps of the embodiment of the present application are described below:
[0096] S301 : Obtain the target pulse widths of the preset number of target seeds corresponding to the target seed type that are collected most recently.
[0097] In the embodiment of the present application, when the number of seeds corresponding to the target seed type increases by a preset number, the target pulse width of the preset number of target seeds corresponding to the target seed type collected the most recently is obtained. The target pulse width refers to the pulse width of the voltage value in the pulse caused by the target seed being greater than or equal to the reference threshold voltage.
[0098] The target pulse width of the target seed is obtained by subtracting the time point when the voltage value of the falling edge of the pulse caused by the target seed is the reference threshold voltage from the time point when the voltage value of the rising edge of the pulse caused by the target seed is the reference threshold voltage.
[0099] S302 , updating the maximum pulse width reference value or the minimum pulse width reference value according to a first difference between each target pulse width and a maximum pulse width reference value and a second difference between each target pulse width and a minimum pulse width reference value.
[0100] In an embodiment of the present application, the number of target pulse widths whose first difference is less than the second difference is counted to obtain a first number; the number of target pulse widths whose first difference is greater than the second difference is counted to obtain a second number; and based on the numerical relationship between the first number and the second number, the maximum reference value of the pulse width or the minimum reference value of the pulse width is updated based on all target pulse widths.
[0101] The first difference is obtained by subtracting the absolute value of the difference between the target pulse width and the maximum reference value of the pulse width, and the second difference is obtained by subtracting the absolute value of the difference between the target pulse width and the minimum reference value of the pulse width.
[0102] For example, if the target pulse width is 5 s and the maximum pulse width reference value is 8 s, then the first difference between the target pulse width and the maximum pulse width reference value is |5-8|=3 s.
[0103] Specifically, if the first number is greater than the second number, the pulse width maximum reference value is updated according to all target pulse widths whose first difference is less than the second difference.
[0104] In the embodiment of the present application, if the first number is greater than the second number, it means that there are more target pulse widths closer to the maximum reference value of the pulse width, so the maximum reference value of the pulse width is updated. The average value of all target pulse widths whose first difference is less than the second difference can be determined as the updated maximum reference value of the pulse width. It is also possible to perform a weighted summation on all target pulse widths whose first difference is less than the second difference to obtain the updated maximum reference value of the pulse width.
[0105] Specifically, if the first number is smaller than the second number, the minimum pulse width reference value is updated according to all target pulse widths whose first difference is larger than the second difference.
[0106] In the embodiment of the present application, if the first number is less than the second number, it means that there are more target pulse widths closer to the minimum reference value of the pulse width, so the minimum reference value of the pulse width is updated. The average value of all target pulse widths whose first difference is greater than the second difference can be determined as the updated minimum reference value of the pulse width. It is also possible to perform a weighted summation on all target pulse widths whose first difference is greater than the second difference to obtain the updated minimum reference value of the pulse width.
[0107] Based on the same inventive concept, an information processing device corresponding to the counting method of the photoelectric seed sensor is also provided in the embodiment of the present application.
