People working indoors often respond very differently to levels of thermal comfort in the office, which is directly related to health and work efficiency. Up to now, the dilemma of thermal comfort for all and energy efficiency in the process remains unsolved. A local dynamic thermal comfort model is established in this paper based on the CFD software. Local parameters are designated and all-around...
In order to improve reliability and speediness of access control system, in hardware design, the shortcomings of access controller with a CPU is analyzed in this paper. The core module of the hardware system is designed based on two microcontrollers. In software design, main program and subprogram are programmed according to coordinate and independent mode. The card reader controlling, door magnetism...
In order to transmit the field data to the monitoring center and monitor the production process in real time, the characteristics of field instruments signal are analyzed, a all-purpose wireless transmission device for field data is designed, which is developed based on MSP430 Microcontroller. For the sake of acquiring the field data and not disturbing instrument signal to transmit to the original...
When one room fires in a building, the design scheme of fire auto alarm and intelligent escaping system for occupant evacuation in fire is in this paper proposed in order that people can fleetly escape the fire field. Fire auto warning, smog sensor measuring, calculating optimal path and showing optimal escaping path are realized by use of simulating occupant distribution and building structure in...
In order to investigate control method for indoor thermal comfort, the experimental environment of indoor thermal comfort is designed in this paper. Thermal comfort data are collected based on questionnaire means, ANN (artifical neural network) is trained using the data, and the ANN model trained can accurately forecast thermal comfort index. Relevant input parameters is conversely computed based...
In order to improve the management efficiency and convenience of the access control system in intelligent building, according to the new demand, a network entrance guard management software has been in this paper developed based on original software for single computer system. Inquiring real-time network data, browsing real-time information and long-distance monitoring can be realized by use of the...
