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...
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...
