水田拖拉机打滑率和下陷深度检测装置Slip rate and subsidence depth detection device for paddy tractor

技术领域technical field

本发明涉及检测自动化技术领域,具体涉及一种水田拖拉机打滑率和下陷深度检测装置。The invention relates to the technical field of detection automation, in particular to a device for detecting the slip rate and subsidence depth of a paddy field tractor.

背景技术Background technique

拖拉机在水田环境下行走和作业时,由于此类土壤水分过大、土壤坚实度小而导致拖拉机轮子或履带的打滑和下陷。打滑和下陷降低了拖拉机的行驶通过性和操作性,增加了燃油消耗,严重时可造成拖拉机无法行走作业,降低了水田环境下拖拉机的作业效率,进而影响到水田粮食产出的成本。When a tractor walks and operates in a paddy field environment, the wheels or tracks of the tractor will slip and sag due to excessive soil moisture and low soil firmness. Slippage and subsidence reduce the tractor's driving ability and operability, increase fuel consumption, and in severe cases can cause the tractor to be unable to walk and operate, reduce the tractor's operating efficiency in the paddy field environment, and then affect the cost of grain output in paddy fields.

拖拉机打滑率检测尤为重要,现有技术中,例如公开号为CN204882084U的中国实用新型专利公开了一种拖拉机打滑率检测装置,包括光栅板、接近开关、控制器和显示器,所述的光栅板与驱动轮的轮毂固定,光栅板的外周间隔设有多个感应片,所述的感应片以轮毂中心轴为中心圆形分布,所述的接近开关设置在光栅板的侧部且刚好与上述感应片的运动轨迹正对,接近开关和显示器均与控制器电性连接。该拖拉机打滑率检测装置能在不影响机械工况直接测试完成,测试结果准确。另外,现有技术中,常规车辆的打滑率是通过测量出驱动主轴转速和车体速度后计算得出。驱动主轴转速利用驱动主轴附近的反射式红外光电传感器测量,车体速度利用卫星定位(GPS、RTK)或五轮仪等方法测量。然而在水田环境下,拖拉机行走系统很容易将水田里的泥水泼溅至驱动主轴附近,产生光的漫反射现象或遮挡光源,增加检测误差或造成检测光信号读取失败,利用卫星定位则存在零偏漂移和成本昂贵等问题。Tractor slip rate detection is particularly important. In the prior art, for example, the Chinese utility model patent with publication number CN204882084U discloses a tractor slip rate detection device, including a grating plate, a proximity switch, a controller and a display. The hub of the driving wheel is fixed, and the outer periphery of the grating plate is spaced with a plurality of induction sheets. The induction sheets are circularly distributed with the central axis of the wheel hub as the center. The motion track of the film is facing, and the proximity switch and the display are electrically connected with the controller. The tractor slip rate detection device can be directly tested without affecting the mechanical working condition, and the test result is accurate. In addition, in the prior art, the slip rate of a conventional vehicle is calculated by measuring the rotational speed of the driving main shaft and the speed of the vehicle body. The rotational speed of the driving spindle is measured by a reflective infrared photoelectric sensor near the driving spindle, and the vehicle body speed is measured by satellite positioning (GPS, RTK) or a five-wheel meter. However, in the paddy field environment, the tractor walking system can easily splash the muddy water in the paddy field to the vicinity of the drive spindle, resulting in diffuse reflection of light or blocking the light source, increasing the detection error or causing the failure to read the detection light signal. Zero offset drift and high cost.

现有技术中,下陷深度通过测量车体某固定点与某一基准面(如地面) 之间的距离来获取。然而水田中的基准面是水面,水面会对光、超声波等媒介的传播产生漫反射现象,同时水面会受到拖拉机行走系统的影响而时刻发生大幅度波动,这使得采用激光、超声波、视觉等方法不能获取准确的距离值。In the prior art, the subsidence depth is obtained by measuring the distance between a certain fixed point of the vehicle body and a certain reference plane (eg, the ground). However, the reference surface in the paddy field is the water surface. The water surface will produce diffuse reflections on the propagation of light, ultrasonic waves and other media. At the same time, the water surface will be affected by the tractor walking system and fluctuate greatly at any time, which makes the use of laser, ultrasonic, visual and other methods. The exact distance value cannot be obtained.

由于连续水面的存在,水田中拖拉机行驶中打滑率和下陷深度的检测环境远比旱地条件恶劣,现有检测技术由于不能克服泥水泼溅、水面扰动带来的检测误差和成本问题限制了打滑率和下陷深度检测装置在水田拖拉机中的应用。Due to the existence of continuous water surface, the detection environment for slip rate and subsidence depth of tractors in paddy fields is far worse than that in dry land. The existing detection technology cannot overcome the detection error and cost problems caused by splashing mud and water surface disturbance, which limits the slip rate. And the application of subsidence depth detection device in paddy field tractor.

有鉴于水田环境的特殊性,与现有技术相比,提供一种易于安装拆卸、受泥水干扰小、能提高检测精度和检测实时性、无线传输、便于用户实时查看拖拉机行驶时打滑率和下陷深度显示数据的检测装置具有重要的实用价值。In view of the particularity of the paddy field environment, compared with the prior art, it is easy to install and disassemble, less disturbed by mud and water, can improve detection accuracy and real-time detection, wireless transmission, and it is convenient for users to check the slip rate and subsidence of the tractor in real time. The detection device of depth display data has important practical value.
