B, wireless mode: the independent RFID card reader of split is passed through 433MHZ, 900MHZ or 2.4G or other frequency ranges and is connected with OBU, carries out information exchange by wireless mode and OBU.Concrete, in front dress OBU, carry wireless card reading module, realize wireless and contactless Card Reader.Same, independent RFID card reader can adopt contact Card Reader and two kinds of modes of contactless Card Reader.
In front dress OBU, be equipped with bluetooth module, after connecting with car owner's Bluetooth of mobile phone by the bluetooth module on front dress OBU, status information data current automobile can be fed back to car owner by mobile phone in time as toll station's information or distribution or the maintenance upgrade information etc. of the dealing money of front dress OBU, trade date, process, allow car owner by the Long-distance Control of mobile phone, just can view the relevant information of OBU.
In addition, if front dress OBU is connected with the CAN bus of automobile by CAN interface, front dress OBU may be read into status information and the maintenance information etc. of vehicle by CAN bus, again by the bluetooth module of front dress OBU inside, can or be equipped with the relevant information of the user feedback vehicle of the equipment of bluetooth module to mobile phone equally, be beneficial to user's maintenance and safeguard automobile.
Front dress OBU is connected with the CAN bus of automobile by CAN interface, can also realize the binding relationship of front dress OBU and automobile, thereby realize tamper function.Concrete anti-disassembling function comprises three processes: distribution activation, the testing process that powers on and detection tamper failure procedure.
(1) distribution activation, realization flow is as follows:
RSU reads the system information of front dress OBU;
The legitimacy of dress OBU before RSU checking, if illegal, distribution activates unsuccessfully, exits, legal words are carried out next step;
Front dress OBU obtains the VIN code of vehicle by CAN bus;
Front dress OBU analyzes VIN code, sees whether VIN code is data available, if VIN code mistake, distribution activates unsuccessfully, exits, if VIN code is correct, carries out next step;
Front dress OBU saves VIN code, and as the VIN code of later checking use, the success of distribution activation process, exits distribution activation process.
(2) testing process that powers on, realization flow is as follows:
After powering on, front dress OBU carries out initialization;
Front dress OBU judges whether to issue, if do not had, points out OBU not issue to user, and exits the testing process that powers on, if had, enters next step;
Front dress OBU can obtain by CAN bus the VIN code of vehicle from automobile;
The checking VIN code of preserving in the VIN code of obtaining and front dress OBU is compared;
If result difference more out, or cannot inquire VIN code because the reasons such as CAN interface disconnection cause, before illustrating, dress OBU has been disassembled, Anti-dismantling lost efficacy, OBU meeting recording status, and notify user's Anti-dismantling to lose efficacy, then exit tamper testing process.
(3) detect tamper failure procedure, realization flow is as follows:
In front dress OBU operational process, can regularly remove to inquire about VIN code.
Front dress OBU judges whether to issue, if do not had, exits timing query script, if had, enters next step;
Front dress OBU can obtain by CAN bus the VIN code of vehicle from automobile;
The checking VIN code of preserving in the VIN code of obtaining and front dress OBU is compared;
If result difference more out, or cannot inquire VIN code because the reasons such as CAN interface disconnection cause, before illustrating, dress OBU has been disassembled, Anti-dismantling lost efficacy, front dress OBU meeting recording status, and notify user's Anti-dismantling to lose efficacy, then exit tamper testing process; If coming to the same thing more out, the query time of waiting timer, repeats 1-4 step above.
It should be noted that in addition, the realization of above-mentioned tamper function belongs to prior art, do not relate to the change of software flow, it is 2012.08.17 that the realization of tamper function specifically please refer to the applying date, application publication number is CN103177481A, and invention and created name is the patent publication of " have the vehicle control system of the anti-disassembling function of electronic charging terminal and utilize the anti-method for dismounting of electronic charging terminal of this function ".
Front dress OBU is also equipped with infrared module, and car owner can operate front dress OBU by Infrared remote controller.Infrared remote controller is the accessory of front dress OBU, supports the use with front dress OBU.Can also there is the Infrared push button module supporting with front dress OBU infrared module in position collocation such as the instrument carrier panel of automobile, bearing circle, Door Handles, by Infrared push button module, can adopt the front dress of wireless mode control OBU.
Can realize the volume control of switching on and shutting down, function setting and the loud speaker of front dress OBU by the button of man-machine interaction unit, before indicator lamp shows, current mode of operation, the loud speaker of dress OBU can be reported dealing money and remaining sum, facilitate car owner to understand the status information of smart card, display module can show dealing money and remaining sum.
Upgrade interface is used for the software system of carrying in front dress OBU control unit to upgrade, and one of upgrading idiographic flow is:
(1) arrive front dress OBU at upgrade interface place access mobile memory medium, in mobile memory medium, store software system preamble, software system kernel and the application program of latest edition;
(2) preamble of dress OBU software system before startup;
(3) software system start, and load latest edition software system preamble, software system kernel in mobile memory medium;
(4) software system are restarted, and automatically upgrade application software.
Front dress OBU, by button, loads software system preamble, software system kernel and the application program of the latest edition in mobile memory medium automatically, and mobile memory medium can be any in USB flash disk, SD card, T card or portable hard drive; The connecting interface that mobile memory medium can be set in places such as the console of the front automobile that fills the surface of OBU or be connected with front dress OBU, bearing circle, Door Handles, interface shape is various, and optimum is USB interface.
Due to the working environment more complicated of front dress OBU, the generation of the situation such as interference, power-off suddenly of abnormal condition, likely cause software system normally to start, or the software that has new edition needs to upgrade, if employing traditional approach, the machine of tearing open carries out the system mode of burning again, the disadvantage such as have that cost is higher, the time of inefficiency, reparation is long, adopt by mobile memory medium repair or upgrade before fill the technical scheme of software system in OBU control unit, reduced operation complexity, saved cost and time.
