Fire Equipment Power Monitoring System

The fire-fighting facilities failed to play in its true role during the fire disaster,that will lead to the disaster expension.So the people began to pay attention to the capability of fire facilities.The majority reason about the fire facilities can’t working properly is the fault of original power supply.In this case,many fire-fighting facilities become a decoration,and was unable to complete its own effectiveness in time.This case expand fire accidents directly.This thesis describes the importance of fire-fighting equipment power monitoring system,including its developed and the current research situation.The thesis lists some of the requirements of fire equipment voltage monitoring system from mandatory national standard(GB-28184).The subsequent chapters have introduced the design of this dissertation, including hardware design, software design, and the overall design of the framework.At the end,the thesis introduce a simple diagram used in the installation project.The highlight of the thesis is that it combine the DMA and the serial transceiver.This way have more efficient than the tradional ways.The thesis also develop the MODBUS protocol and to solve the partical problem in engineer which fire fighting equipment power monitoring needs.Fire equipment voltage monitoring system divided into two main parts, the monitoring host and sensor sampling information transmission. Considering the cost and stability,both of them are use the PIC24 microcontroller.The sensor is used to collecting the current power supply signaling equipment,including voltage and current leakage,etc.The communicates via is based on the RS-485 bus.The host get the current value of all the sampled current or voltage sensor are based on this communications via.The monitor host will process the resulting value which it achieved from the sensor.The host computer monitor is responsible for the information collection and the display of current alarm record.The system use the MODBUS-RTU communication protocol but does not exactly the same as the classic format.The third chapter of the article has describe the format of the communication protocol of the system.The system include a PC programme which develop by MFC development.And there is an automatic calibration system included.The automatic calibration system can calculated the linear curve sampling through acquisition and manually enter information in the standard value.The design and verification of the entire system is according with the national standards(GB28184-2011), "fire-fighting equipment power monitoring system".Through a variety of tests,the system can ensure the stability by many Interference tests.The Fire equipment power monitoring system designed in this thesis is suitable for most occasions which is required the fire-fighting equipment.It can solve the need of the fire-fighting equipment market,and it also improve the safety of the large group of building fire protection facilities,reduce the security risks significantly.This design can played a national preventive measures advocated by the requirements.
