Background technology
At present, distribution system causes in the building construction work personal safety as well as the property safety problem and the system failure, the overwhelming majority is because excessive the causing of leakage current of equipment and circuit, the electrical fire that the factors such as aging circuit, breakage and overload that are accompanied by cause has occupied more than 34% of high-rise building building fire, ranks first in the fire cause always.Preventing with the method for effectively controlling electrical fire also in continuous raising, with more efficient means protection personal safety and property safety simultaneously.
According to the relevant regulations of GB14287 and earth's surface, Anhui Province DB34/T 855-2008 as can be known electric fire monitoring system formed by electrical fire monitoring device and residual current type detector for electric fire protection.Residual current type detector for electric fire protection is mounted to each monitoring point, is connected to electrical fire monitoring device by fieldbus.Every detector for electric fire protection of electrical fire monitoring device poll monitoring is reflected to residual current in user's hand in real time.But in Practical Project, substantially take the hardwire mode to carry out the wiring of electric fire monitoring system, can only realize simple " point " information, complicated wiring also can affect the exchanges data of electric fire monitoring system usually, especially in complicated building construction engineering, arranging of bus is a loaded down with trivial details engineering, also improved installation cost and construction speed simultaneously.
The utility model content
Technical problem to be solved in the utility model has provided a kind of being applied to and need not the engineering wiring in the complicated middle-size and small-size building engineering, and the radio short networking is simply installed, and realizes the electric fire monitoring system of Real Time Monitoring.
The utility model principal feature is: be made of electrical fire monitoring device and residual current type detector for electric fire protection, its electrical fire monitoring device is made of master cpu circuit, active and standby electric control circuit, high-decibel audible alarm circuit, liquid crystal display circuit, and the upper end that the output terminal of its master cpu circuit arranges a liquid crystal display circuit, other output control circuits, a high-decibel audible alarm circuit, master cpu circuit links to each other with active and standby electric control circuit; Its residual current type detector for electric fire protection is made of the master cpu circuit, and the output terminal of its master cpu circuit arranges a liquid crystal display circuit, other output control circuits, a leakage current detection circuit, a high-decibel audible alarm circuit; It is characterized in that: the upper end of master cpu circuit all arranged one 485 telecommunication circuits, a ZigBee radio communication circuit during the monitoring of the lower end of master cpu circuit and residual-current electrical fire was surveyed in the electrical fire monitoring device.
The beneficial effects of the utility model are: the utility model makes things convenient for field wiring and installation greatly by adopting the ZigBee wireless network to carry out the short distance networking, reduced engineering cost, also improved operating efficiency, possess simultaneously the high-level efficiency and the real-time that monitor leakage current, native system current collection power system, application electric technology, electric automatization, wireless communication technology, the great achievement of Analogical Circuit Technique utilization, take computer and network technologies as support, in the face of system comprehensively designs, optimizational function and simplification system, use dispersion, distributed frame is realized OO thought, can reliable long-term work operation under the abominable industrial environment of complexity.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Fig. 2 is ZigBee radio communication circuit figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1 and Figure 2, electric fire monitoring system is comprised of 1 electrical fire monitoring device and Duo Tai residual current type detector for electric fire protection.Electrical fire monitoring device carries out the poll monitoring by the ZigBee wireless communication module to residual current type detector for electric fire protection, and the packet that residual current type detector for electric fire protection receives by the ZigBee wireless communication module and the coupling electrical fire monitoring device is sent carries out the answer of valid data.Detector 4 far away is communicated by letter until valid data are sent to electrical fire monitoring device with near detector 3 by the ZigBee wireless communication module.Can communicate to connect to detector 3 by 485 for the detector 5 that is in the more complicated environment, finished the transmission of data by detector 3.Also can all use simultaneously 485 communications to carry out exchanges data.
The main characteristics of the utility model are to adopt the ZigBee communication to carry out networking, in the small and medium construction engineering of the more complicated that can be applied to connect up.Thoroughly change traditional hard wired method, greatly improved operating efficiency.By level transferring chip, can control the ZigBee wireless communication module, realize the real-time radio transmission of data.
Be illustrated in figure 2 as the ZigBee wireless communication module by being connected of serial ports conversion and master cpu, its module pinout is as follows:
RXD: data receiver
TXD: data send
CTS: know data
RTS: request msg
Reset: reseting module
I/O control: I/O mouth input and output
The ZigBee wireless communication module is a short-range wireless network that is applicable to industrial environment, high-performance, low-power consumption and low cost, work in the above public frequency range of the free 2.4G in the whole world, conversion is sent to the master cpu connection through serial data, and master cpu is by analyzing transmission and the acceptance that sends instructions to finish the ZigBee radio communication under the packet.
