“…The continuous change of outdoor environment factors constantly affects the condition of environment in mushroom house. The uncertainty is an unavoidable problem in the control system [31][32][33] . Therefore, the control algorithm must adjust its parameters in real-time according to the situation of mushroom house.…”

Environment parameters are the main factors affecting the growth and development of Agaricus bisporus. Because of the requirements of environmental conditions for high-efficiency industrialized production of Agaricus bisporus, equipments for environment control were developed. Based on the variable operating equipment, a multi-factor fuzzy controller was designed to realize the comprehensive control of ambient temperature, humidity, CO 2 concentration, and the temperature and moisture of the compost. The test results showed that the temperature control error was less than ±0.5°C and the response speed was more than 0.5°C/h; The control error of ambient humidity was less than ±2% RH, and the response speed was more than 9% RH per hour; The moistures at different points in compost ranged from 50% to 70% with a standard deviation of 4.04. The control accuracy of environmental CO 2 concentration was within 200 µmol/mol. The overall performance of the control system was stable and reliable, which could meet the requirements of environment factors for the growth of Agaricus bisporus. The system can provide technical support and reference for the automatic and precise control of the environment during the industrialized production of Agaricus bisporus.

“…An advanced system was developed in order to detect and control the frame vibration caused by a high-power engine and to prevent/reduces the potential damage to agricultural machinery [ 23 , 24 ]. It is based on intelligent sensor nodes at the measuring points of the two-stage vibration isolation system with the aim to assess the acceleration values and the frequency spectrums [ 24 , 25 ]. But few works have been conducted with respect to those with the problem of WBV exposure [ 26 ].…”

This paper aims to investigate failures induced by vibrations on machines, focusing on agricultural ones. The research on literature has brought to light a considerable amount of data on the driven vehicles and not much on the operating machines, including the ones that we looked for. For this reason, it was decided to direct a survey with the people who work with agricultural machinery every day: operators, sub-contractors, and producers. They were asked about the most frequent breakage, particularly in relation to the rotary harrow, the topic of this work. The questionnaire results showed the types of failures the harrow is most vulnerable to, indicating the times of failure and reparation and the need to set up a potentially useful preventive maintenance supporting system on these machines. Part of the work was then focused on the proposition of a method to investigate bearing failures in the rotary harrow, considering that these have been analyzed in the technical literature and in the survey as the most at-risk components. The proposed method in this work serves as a beginning for the development of a future on board sent-shore-based maintenance system for continuous monitoring of the bearing.

“…According to the type of planter, it can be divided into clamp type, flexible disc type, hanging cup type, guide seed tube type, double conveyor belt type, slide branching wheel type and duckbill type. Therefore, it is necessary to optimize the design parameters and key components of vegetable transplanters on the basis of research on vegetable seedling conditions and transplanting effects [11][12][13][14][15] .…”

In order to improve the efficiency and quality of transplanting vegetables in dry land, based on the seedling technology, transplanting effect and analysis of the planting process, a potted vegetable seedlings transplanting machine was designed. It mainly comprised rotary disc type feeding mechanism, five-bar duckbill type planting mechanism (simulated duckbill mechanism, disc cam, connecting rod, crank, fork, cable) and power transmission system. Based on the physical parameters of the seedlings and design requirements, it was determined that the diameter of the duckbill was D=90 mm, the opening and closing angle was 25°, and the taper angle was 17°. A test bench with adjustable parameters was built by analyzing the structure of the planting mechanism and the motion of the working process. The digital speckle technique was used to optimize the parameters, so that the length of the crankshaft Ι was S 1 =100 mm, the length of the crankshaft ΙΙ was S 2 = 80 mm, the length of the connecting rod Ι was S 3 =140 mm, the length of the connecting rod ΙΙ was S 4 =260 mm, the length of rod to connecting the rack was S 6 =314 mm, and the height of planting track was H=450 mm. According to the above parameters and the control requirements of the duckbill mechanism, the cam stroke was determined to be S=15 mm. And the initial phase difference between the two cams was 180°. The experiment was carried out with pepper seedlings as transplanting objects. The results showed that when the planting frequency was 50-70 plants/min, the seedling upright rate was 93%-91.1%, the planting depth qualified rate was 96%-92%. The leakage rate was 0-0.26%, the variation coefficient of plant spacing was 0.37%-0.67%, the injury rate was 0%, and the mechanical damage degree of the mining surface was 2.43-3.77 mm/m 2. The machine can effectively improve the quality of transplanting, which can meet the production needs and design requirements of the mechanism.
