Building a method that evaluates the fitness of greenhouse for crop has a great significance for the development of greenhouse. In this paper, a design of greenhouse environmental detection system based on AHP (analytic hierarchy process) comprehensive fuzzy evaluation is proposed to approach the goal of evaluation. Multiple sensors are used to detect environment and the wireless transmission network based on Zigbee is used to transmit environmental data. The temperature, air humidity, illumination, CO2concentration and soil moisture are used as the evaluation factors. The appropriate membership function is selected to build the membership matrix and the AHP is used to construct the weight vector set. The environment of greenhouse can be evaluated by the calculation of membership matrix and weight vector set.","PeriodicalId":287095,"journal":{"name":"2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123542467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the diversity of elderly service resources, the third-party institutions is used to integrate the service resources. The non peer two-way cross chain resource coordination mechanism is proposed, and the model of the clustered elderly system is built based on the method of system dynamics. Three evaluation indexes of bullwhip effect, total resource level and service satisfaction are selected to simulate and analyze the model by using the Vensim software. The results show that the resource coordination model can effectively realize the resource complementation. Compared with the single chain mechnisim, the mechinisim we proposed significantly reduces the total resource level of a single supply chain, effectively improves service satisfaction, and greatly weakens the bullwhip effect.","PeriodicalId":287095,"journal":{"name":"2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115679173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to monitor magnetic bearing temperature for fault detection, an online estimation method of bearing temperature is proposed. First, the model of power amplifier is established. Next, the parameter identification algorithm is used to identify the coil resistance online, and then the temperature of the AMB can be estimated indirectly according to the relationship between resistance and temperature. Simulation results show that the proposed method can converge the estimated temperature rapidly in the presence of noise.","PeriodicalId":287095,"journal":{"name":"2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123562865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These modules cooperate with each other and can be used to monitor the user's posture in real time. The Signal Magnitude Vector algorithm (SMV) is used to distinguish whether the elderly fell. If fall was happened, the user's location information will be automatically sent to the emergency contact, and an alarm sounds.

This study proposes a feature denoising-based fault diagnosis method for rotating machinery. In the proposed method, raw signals are firstly decomposed into several subsignals of different frequency bands using the empirical mode decomposition. Based on these subsignals, multiple fault features are extracted. Then, variational mode decomposition (VMD)-based feature denoising technique is used to process the obtained features. Finally, a random forest classifier is applied to identify different machinery faults. Experimental results show that the VMD-based feature denoising approach can effectively remove the noise data and largely improve the classification performance.","PeriodicalId":287095,"journal":{"name":"2020 35th Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"33 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120901660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
