Abstract
The utility model relates to a network-based intelligent safety protection device. At the device, the infrared detection module transmits the detected invasion signal to the master controller at the slave computer via the CAN bus communication control module. And the infrared detection module converts the data signal from the master controller at the slave computer into the USB protocol signal via the CANTOUSB protocol converter and then sends the data signal to the client terminal of the USB equipment. Then, the infrared detection module transmits the data signal via the USB bus to the master computer and vice versa. Further, the control signal from the master computer is transmitted to the stepping motor via the CANTOUSB protocol converter, the master controller at the slave computer and the CAN bus communication control module. It is the stepping motor to accomplish the safety protection operation. The unity model characterizes simple structure, easy operation, high accuracy and reliability and low cost, etc. The unity model could detect the invasion signal, analyze and judge intelligently the relation among a plurality of detection data, judge rightly the alarm signal and execute the protection measures.
Description
Technical field

Background technology
At present, along with the raising of socioeconomic continuous development and science and technology, the intension of safety precaution product is also more and more abundant, and the security protection industry develops into the closely-related industry of living with the social economy and the people gradually.Safety-protection system generally is bus with RS485 now, realize host computer PC and slave computer master controller mutual communication, have that the information transmitting range is short, speed slow, poor stability, connection node are few, be difficult to realize shortcoming such as networking, can't satisfy its intelligentized development trend.The utility model adopts USB and CAN (Conctroller AreaNet controller local area network) bussing technique.The plug and play of USB technology, advantages such as transfer rate, use the utility model of being up to 480M/S have more hommization and intellectuality; The outstanding behaviours more stable on industry spot, that have more real-time of CAN bus makes the utility model realize networking.Connect each module of slave computer main controller controls by the CAN bus, communicate by letter the intelligent modern safety-protection system of a networking of composition by what usb bus was realized slave computer master controller and host computer (PC).
The utility model content
The purpose of this utility model is that present safety apparatus information transmitting range is short in order to solve, speed is slow, poor stability and node are few, be difficult to realize technical matterss such as networking, intellectuality; provide a kind of simple in structure, easy to operate, degree of accuracy is high, reliable operation, network-enabled intelligent safety apparatus that cost is low; can the detecting intrusion signal; intelligent analysis and judge relation between the various detection datas; make correct judgement, realize safeguard measure alerting signal.
The utility model comprises the host computer PC; the USB device client; CAN TOUSB protocol converter; the slave computer master controller; CAN bus communication control module; infrared detection module; stepper motor; infrared detection module sends detected invasion signal to the slave computer master controller by CAN bus communication control module; become the data shift signal of slave computer master controller the usb protocol signal conveys to give the USB device client by CAN TO usb protocol converter again; then by usb bus and the mutual data signal of host computer PC; again by CAN TO usb protocol converter; the slave computer master controller; CAN bus communication control module sends the control signal of host computer PC to stepper motor, finishes the safeguard protection operation by stepper motor.
The utlity model has simple in structure, easy to operate, degree of accuracy is high, reliable operation, low cost and other advantages; can the detecting intrusion signal; intelligent analysis and judge relation between the various detection datas is made the correct judgement to alerting signal, realizes safeguard measure.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1 host computer PC, 2 USB device clients, 3 CAN TO usb protocol converters, 4 slave computer master controllers, 5 CAN bus communication control modules, 6 infrared detection module, 7 stepper motors.
Specific implementation method
Further specify the organization plan of the present utility model and the course of work in conjunction with example.
As shown in Figure 1, a kind of intelligent and safe crime prevention device of networking comprises host computer PC 1, USB device client 2, CAN TO usb protocol converter 3, slave computer master controller 4, CAN bus communication control module 5, infrared detection module 6, stepper motor 7.
The course of work of the present utility model is: infrared detection module 6 sends detected invasion signal to slave computer master controller 4 by CAN bus communication control module 5; become the data shift signal of slave computer master controller 4 the usb protocol signal conveys to give USB device client 2 by CAN TO usb protocol converter 3 again; then by usb bus and host computer PC 1 mutual data signal; again by CAN TO usb protocol converter 3; slave computer master controller 4; CAN bus communication control module 5 control signals with host computer PC 1 send stepper motor 7 to, finish the safeguard protection operation by stepper motor.
All be to adopt the CAN bus to connect between each module of the slave computer main controller controls of this real utility model, communicate by letter between slave computer master controller and the host computer PC and realize by USB.
The utility model adopts the AT89C51 single-chip microcomputer as the slave computer master controller, and infrared detection module, stepper motor, CAN bus control module are realized control.
Infrared detection module comprises infrared transmission module and receiver module.Infrared transmission module: connect at the INFRVCC place+5V voltage, in the fixed frequency of DATCLK place input 37.9KHz, infrared transmitting tube just can send fixing frequency continuously, and infrared receiving module also can receive fixing frequency, and system normally moves.If people's process is arranged therebetween, cause receiver module can't receive the signal that power valve sends, system just can report to the police.Adopt PIC-1018SCL as receiver module.
The CAN bus is used to the communication bus of the intermodule of slave computer main controller controls.CAN bus system intelligent node of the present utility model adopts the microprocessor of 89C51 as node, adopts the SJA1000 and the 82C250 of PHILIPS company in the CAN bus communication interface.Chip SJA1000 is independent CAN communication controler, and 82C250 is a high-performance CAN bus transceiver.
Be used as communicating by letter between slave computer master controller and the host computer PC at usb bus of the present utility model, adopted the USB interface device PDIUSBD12 of the band parallel bus of philips company.With the program design of single-chip microcomputer C51 language realization slave computer master controller, realize the design of host computer PC user interface program with the VC++ language.
