and experimentally verifies a method for determining the position and geometric parameters of agricultural machinery for automated washing process control.The method combines photoelectric sensors for verifying the admissible position of the machinery and ultrasonic sensors for determining distances to its upper and side surfaces.Median filtering is used to reduce the influence of anomalous ultrasonic measurements, while the measured distances are converted into geometric parameters using the known dimensions of the experimental installation.The obtained parameters are used by the controller to define the permissible operating area and generate control actions for the washing carriage, pump, and air-blowing system.If the machinery is positioned incorrectly or exceeds the permissible dimensions of the working zone, the technological cycle is blocked.Experimental verification using the developed automated washing installation and a tractor model confirmed correct operation of the positioning subsystem and sufficient accuracy of ultrasonic measurements.The maximum absolute error did not exceed 2 mm.The proposed approach provides direct integration of sensor measurements into the control logic and enables adaptation of the washing cycle to the actual position and dimensions of the machinery.Further research should address the integration of computer vision and adaptive generation of washing-carriage trajectories.","本文提出并实验验证了一种用于自动化清洗过程控制的农业机械位置与几何参数确定方法。该方法结合光电传感器验证机械的允许位置，并利用超声波传感器确定其顶面和侧面距离。采用中值滤波降低异常超声测量的影响，同时利用实验装置的已知尺寸将测量距离转换为几何参数。控制器利用所得参数确定允许作业区域，并生成对清洗小车、水泵和吹风系统的控制动作。若机械位置不正确或超出工作区允许尺寸，则封锁工艺循环。利用所开发的自动化清洗装置和拖拉机模型进行的实验验证，证实了定位子系统的正确运行以及超声测量的足够精度。最大绝对误差不超过2

China","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1978360","Introduction Tax incentives can support agricultural-machinery investment, but their value depends on taxable capacity, documentary evidence, and timing. Methods We use a policy-calibrated single-case simulation of Company A to evaluate 432 prespecified lifecycle rules across ten demand-policy stress paths for 2026–2033. The model integrates value-added tax, corporate income tax, R&D incentives, tax-loss and credit vintages, investment timing, and model-implied adjustment exposure. Scenario weights are judgmental rather than estimated frequencies. Results The constrained rule combines 7% R&D, equipment and retrofit in 2026, straight-line tax depreciation, and no exemption-based separate accounting. Its expected NPV is CNY 16.82 million and its 20% lower-tail CVaR is CNY 12.61 million. Expected NPV is 5.40% higher than under Company A’s static plan but only 1.51% higher than under baseline compliance. Relative to baseline, CVaR is 5.82% lower and risk-adjusted NPV is essentially unchanged. Discussion These results are conditional on the stated parameters. The proposed food-system pathway is theoretical because machinery adoption, farm output, prices, diets, and nutrition are not observed.","引言 税收激励可以支持农业机械投资，但其价值取决于应税能力、文档证据和时机。方法 我们对公司A进行政策校准的单案例模拟，以评估2026—2033年十条需求政策压力路径下的432项预设生命周期规则。该模型整合了增值税、企业所得税、研发激励、税收亏损与抵免的年份归属、投资时机以及模型隐含的调整敞口。情景权重是判断性的，而非估计频率。结果 受约束规则结合了2026年7%的研发、设备与改造，直线法税收折旧，以及不采用基于免税的单独核算。其预期净现值为1682万元人民币，其20%下尾CVaR为1261万元人民币。预期净现值比公司A的静态计划高5.40%，但仅比基线合规高1.51%。相对于基线，CVaR低5.82%，风险调整后净现值基本不变。讨论 这些结果以所述参数为条件。所提出的食物系统路径是理论性的，因为机械采用、农场产出、价格、饮食和营养均未被观测到。","Frontiers in Sustainable Food Systems","2026-10-12T00:00:00Z",40,64,{"impact":140,"substance":91,"depth":261,"authority":263,"freshness":93,"relevant":20,"comment":375},"以单一企业仿真评估农机投资税收规则，方法有增量但结论为条件性理论推演，产业公共价值有限，可作参考不宜精选。",[377,378,381],{"name":370,"url":367},{"name":379,"url":380},"Frontiers in Sustainable Food Systems 10 2026-10-13","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1978360\u002Ffull",{"name":382,"url":383},"Frontiers in Sustainable Food Systems 10(2026)","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1978360\u002Fabstract",[385,27,386,387,388],"数字乡村","可持续食物系统","农业投资","税收政策",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[],{"status":39,"locked":13,"version":40,"method":41,"evidence":392},{"candidates":393,"agricultural_evidence":46},[394,398,403,408],{"code":32,"score":141,"supported":46,"title":395,"abstract":396,"tags":397},[329],[234],[27],{"code":399,"score":20,"supported":13,"title":400,"abstract":401,"tags":402},"E2",[],[],[386],{"code":404,"score":20,"supported":13,"title":405,"abstract":406,"tags":407},"G3",[],[],[387],{"code":409,"score":20,"supported":13,"title":410,"abstract":411,"tags":412},"I6",[],[],[385],[414,415],"农业机械 投资 税收 激励","农机 生命周期 税负 模拟","农业机械投资税收激励-4795","10.3389\u002Ffsufs.2026.1978360",{"doi":417,"openalex_id":419,"authors":420,"venue":370,"cited_by_count":205,"oa_url":367,"card":423,"direction":427,"ingested_from":362},"W7221573002",[421],{"name":422,"orcid":8},"Mingya Wei",{"tldr":424,"method":425,"finding":426,"direction":427,"opportunity":428},"通过单案例仿真评估中国农机投资在税收激励下的生命周期财务表现与风险。","政策校准单案例仿真，整合增值税、所得税、研发激励与投资时机，评估432种规则。","约束规则预期NPV为1682万元，较静态计划高5.40%，但风险调整后NPV基本不变。","数字乡村与农业信息化","可结合真实农机采用与农场产出数据，验证税收激励对可持续食物系统的实际效果。","2026-10-13T23:30:07.063312Z"]
