Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
Fig. 1 shows the structure being provided with the preferred embodiment of the leakage cable intrusion detector of interface of internet of things of the present invention.Refer to Fig. 1, the leakage cable intrusion detector of the present embodiment is made up of detector main frame 1, leaky cable 2,3.Detector main frame 1 is made up of transmitter unit 11, receiving element 12, processor 13, display unit 14 and power supply 15.Power supply 15 connects transmitter unit 11, receiving element 12 and processor 13 respectively, and transmitter unit 11 and receiving element 12 are all connected leaky cable 2,3, the output terminal connection handling device 13 of receiving element 12, and the output terminal of processor 13 connects display unit 14.
The present invention adopts a ARM7 microcontroller 131 to be the core devices of detector, refers to Fig. 2, and its inside comprises 10 ADC and the asynchronous serial communication interface of 8 passages.The physical circuit of ARM7 microcontroller 131 asks for an interview Fig. 3.
The target detection signal of receiving element 12 sends into the ADC passage of ARM7 microcontroller 131 after amplifying process shaping, target information is produced through computing, by asynchronous serial communication interface, photoelectric isolating circuit 132, channel selector switch 133, target information is transmitted by ethernet interface circuit 135 or RS-485 interface circuit 134 central control room (CCR) externally (Central Control Room).The physical circuit of ethernet interface circuit 135 and RS-485 interface circuit asks for an interview Fig. 4.
Ethernet interface circuit 135 or RS-485 interface circuit 134 are referred to as interface of internet of things circuit.This interface of internet of things circuit can only arrange ethernet interface circuit 135, also can only arrange RS-485 interface circuit 134, also can arrange RS-485 interface circuit 134 and ethernet interface circuit 135 simultaneously.Selector switch 133 has two output terminals, one of them connects the input end of RS-485 interface circuit 134, another connects the input end of ethernet interface circuit 135, and the output terminal of RS-485 interface circuit 134 and ethernet interface circuit 135 is all connected to outside Central Control Room.
Processor 13 separately has the output interface of an alarm relay passage, processor 13 is sampled by adc data, calculate object information data and contrast with the target gate preset, if meet the judgment condition of regulation, when reaching alarm set point, can alarm relay be promoted by the output interface of alarm relay passage simultaneously and pass through photoelectric isolating circuit 132, selector switch 133, ethernet module 135 or RS-485 interface 134 initiatively send warning message and (comprise and illegally open detector, alarm relay line short or open circuit), if do not receive the alarming determining message that central control room (CCR) is sent at the appointed time, detector will send warning message continuously.Therefore the optional Ethernet interface that newly increases of leakage cable intrusion detector or RS-485 interface warning passage are closed-loop data passages, have real-time, alert data is accurate, reliability is high, the feature of strong interference immunity.And this design of the present invention does not need the principle of work changing the transmitting and receiving of original leaky cable detector, and only need to improve the data channel of processor.
Single alarm relay can not identify the reasons such as target invasion, detector faults itself.Adopt the data warning passage of Ethernet interface, RS-485 communication protocol, can real-time Transmission sampled data under the control of detector central processing element, and preferentially report warning message, managerial personnel can understand the real-time working condition of each detector at any time, carry out classification process and take counter-measure for the warning message reported.
Along with the development of network technology, usual warning region installs interlock IP Camera simultaneously, and detects main frame employing network interface data passage, is easy to realize, has saved wiring cost with the foundation of the LAN data transmission channel of central control room (CCR).Meanwhile, have employed optional communication port, the demand of reporting to the police that simultaneously walks abreast can be realized, as owner and security protection center can receive relative alarm information simultaneously, be more conducive to promoting the use of of this product.
Above-described embodiment is available to those of ordinary skill in the art to realize and uses of the present invention; those of ordinary skill in the art can be without departing from the present invention in the case of the inventive idea; various modifications or change are made to above-described embodiment; thus protection scope of the present invention not limit by above-described embodiment, and should be the maximum magnitude meeting the inventive features that claims are mentioned.
