A Novel Remote Monitoring and Control System Based on GSM for Home Security

A powerful and cost effective home security system based on GSM communication network and wireless communication module CC1100 is proposed for anti-theft, fireproofing, waterproofing, anti-gas leak and remote appliance control. The system uses STC89C516 microcontroller as the core and real-timely detects the home environment through a variety of sensors. The dual detections are utilized to reduce the false alarm rate and enhance system reliability and interference immunity. The wireless data transmission is adopted between the main controller and sensor nodes, which does not require a lot of wiring. The bidirection communication between the main controller and the mobile terminal is realized by the GSM networks. Once detecting suspicious activities, the system sends an alarm message to the host’s mobile phone. The user can remotely query the home security status and control the home appliance by the GSM module. The communication is assured within the GSM coverage area, and the distance is unlimited. The GSM short message alarm overcomes the hidden troubles of vulnerable damage and no alarm when calling in the fixed telephone dialing. The interaction interface is optimized. The user can modify the passwords, change the target phone number, alter the upper and lower limits of alarm, query the alarm recording and deploy/cancel defense via the LCD and keyboard. The buttons are installed for help in case of emergencies. The test results show that the system can real-timely monitor and remotely query the home environment, control the appliances and initiatively send alarm messages in case of accidents. The system possesses full function, high reliability, low false alarm rate, strong expansion, friendly user interface and low cost. The application space is very broad.

On the optimal management of the closed-loop management in safe practice of nursing teaching in private hospitals

Objective To study the optimal management of the closed-loop management in safe practice of nursing teaching in private hospitals. Method Through analyzing the causes and problems during the teaching of nursing adverse events, the closed-loop management in safe practice of nursing teaching was investigated, including the closed-loop management team, implementation cycle and range, etc. Totally 100 teachers and 220 students were chosen in 27 clinical teaching departments of our hospital during January 2013 and March 2014. The teachers were divided into experimental group (n=50) and the control group (n=50). The closed-loop management model was applied in experimental group while routing management was applied in control group. At the same time, 220 students' behavior in experimental group was compared before and after the closed-loop management. Through the evaluation of nursing teaching' safe hidden trouble and questionnaire survey, the nursing teaching of both groups were safe. SAS 9.2 was applied to do statistical analysis and non-parametric Wilcoxon Fisher exact test and χ2 test were used. Results The number of teachers' operating key points in experimental group was significantly higher than the control group, with statistically significant differences (46 vs. 15) (P=0.000). The safety hazard times of nursing teaching were 38 and 8 respectively before and after the closed loop management, and the difference was statistically significant (P=0.000).In addition, the comparison before the students' implementing the check system, hospital safety index patients and regulation for technical operations and hospital infection was significant after the closed-loop management (P<0.01 for all). Conclusion The full implementation of the closed-loop manage-ment, effective tracking and prevention in place, can optimize the safety management of nursing teaching.

First, according to the service condition of hydraulic concrete structure, the concrete piezoelectric ceramic smart module is designed and the process manufacturing concrete piezoelectric ceramic smart module is presented. The protecting measures of piezoelectric ceramic piece, the peripheral material constituent, and the pouring links are introduced. Second, an integrated system, which is composed of self-made concrete piezoelectric ceramic smart modules in pair as sensor and actuator, fuzzy inference system, and other auxiliary equipments, is developed to monitor indirectly concrete strength. Its working principle is studied. Finally, an experiment of hydraulic concrete strength is implemented to demonstrate the feasibility and validity of the proposed method and developed system. The concrete piezoelectric ceramic smart modules in pair are taken as sensor and actuator embedded in hydraulic concrete specimens. The wave-based analysis method is adopted to collect the stress wave amplitude data during the pouring process of concrete specimens. The fuzzy inference approach is utilized to build the mathematical model describing the relationship between concrete strength and stress wave amplitude. Based on the above mathematical model, the concrete strength can be identified indirectly.
