Embodiment

Below in conjunction with Figure of description and embodiment the utility model is described in further detail.

Fig. 1 and Fig. 2 show structured flowchart and the structural representation of the starter gear of a kind of OBU system wireless of utility model tamper label checking respectively, this starter gear mainly comprise OBU main body 1 and with the suitable support 2 of OBU main body 1, OBU main body 1 comprises OBU processor 20 and microwave module 30, OBU processor 20 is connected with microwave module 30, the bottom of support 2 is provided with wireless tamper label 50, OBU processor 20 is connected with wireless tamper label 50, also be provided with the detecting module 10 that is connected with OBU processor 20 in the OBU main body 1, on OBU main body 1 or support 2, also be provided with corresponding with detecting module 10 by detecting module 40.

For starter gear described in the utility model, cooperate by detecting module 10 and by detecting module 40, make OBU processor 20 can obtain whether rack-mount information of OBU main part, thereby determine whether to enable the checking action of wireless tamper label, and determine that according to the checking result whether carrying out microwave wakes data manipulation up.Wherein, can be arranged on the OBU main body 1 by detecting module 40, also can be arranged on the support 2.When being arranged on the support 2 by detecting module 40, its workflow is as follows:

After the OBU main part is loaded onto support, OBU processor 20 by detecting module 10 detect on the support by detecting module 40, determine that main part has been installed on the support, 20 pairs of wireless tamper labels 50 of OBU processor this moment carry out the Information Authentication action, if authentication failed, then the 20 prompting user tamper label checkings of OBU processor are unsuccessful, do not carry out microwave and wake data manipulation up; If be proved to be successful, OBU processor 20 prompting user tamper labels are proved to be successful, and initial configuration microwave module 30 is in microwave module and wakes the testing state up, if there is the microwave wake-up interrupts to take place, can carries out microwave and wake data manipulation up.

After the OBU main part is taken off from support, OBU processor 20 detects having been left by detecting module 40 on the support by detecting module 10, determine that main part is removed, OBU processor 20 does not carry out the Information Authentication action to wireless tamper label 50, and whether detecting module 10 continues detecting has by detecting module close.

Wherein, when being arranged on support 2 by detecting module 40, the detecting module 10 of this starter gear can be arranged on the hall device circuit for detecting in the OBU main body, corresponding is the magnet of installing on the support by detecting module 40, the hall device circuit for detecting is arranged on the pcb board of OBU main body, magnet arranges the carriage below of support, as shown in Figure 2.When OBU main body 1 was installed on the support 2, the hall device of hall device circuit for detecting can detect magnet, thereby determined that main part has been installed on the support 2.When Fig. 4 shows detecting module and is the hall device circuit for detecting, the workflow of this starter gear, specific as follows:

After the OBU main part is loaded onto support, OBU processor 20 detects magnet on the support by the hall device circuit for detecting, determine that main part has been installed on the support, 20 pairs of wireless tamper labels 50 of OBU processor this moment carry out the Information Authentication action, if authentication failed, then the 20 prompting user tamper label checkings of OBU processor are unsuccessful, do not carry out microwave and wake data manipulation up; If be proved to be successful, then OBU processor 20 prompting user tamper labels are proved to be successful, and initial configuration microwave module 30 is in microwave module and wakes the testing state up, if there is the microwave wake-up interrupts to take place, can carries out microwave and wake data manipulation up; After the OBU main part was taken off from support, OBU processor 20 left by the magnet that the hall device circuit for detecting detects on the support, determined that main part is removed, and whether the hall device circuit for detecting continues detecting has magnet close.

Product form according to OBU, detecting module 10 in this starter gear and the scheme of the technical scheme that is adopted by detecting module 40 except on the inner hall device circuit for detecting of above-mentioned OBU and the support 2 magnet being installed, if arranged on the OBU main body 1 by detecting module, detecting module 10 is the mechanical switch circuit for detecting, be mechanical switch by detecting module 40, also be provided with on the support 2 simultaneously for triggering the triggering structure 60 that mechanical on off state changes, as shown in Figure 3, triggering structure 60 extruding on the support 2, touch or flick the mechanical switch of OBU main part, make the mechanical switch circuit for detecting self can be opened or whether closed information passes to the OBU processor and install on the support in order to detect the OBU main part, to determine whether to start wireless tamper label is carried out Information Authentication.The workflow of this starter gear, specific as follows:

After the OBU main part is loaded onto support, the mechanical switch of OBU main part is pushed, touched or flick to triggering structure 60 on the support 2, make the state of mechanical switch change, the information that the mechanical switch circuit for detecting changes the mechanical switch state passes to OBU processor 20, processor determines that main part has been installed on the support, 20 pairs of wireless tamper labels 50 of OBU processor this moment carry out the Information Authentication action, if authentication failed, then the 20 prompting user tamper label checkings of OBU processor are unsuccessful, do not carry out microwave and wake data manipulation up; If be proved to be successful, then OBU processor 20 prompting user radio tamper labels are proved to be successful, and initial configuration microwave module 30 is in microwave module and wakes the testing state up, if there is the microwave wake-up interrupts to take place, can carries out microwave and wake data manipulation up; After the OBU main part was taken off from support, OBU processor 20 did not change by the state of mechanical switch circuit for detecting detecting mechanical switch, determines that main part is removed.

Certainly, detecting module with also be not only limited to such scheme by the form of detecting module, can arrange accordingly according to the product form of OBU, reach and detect the purpose whether the OBU main body be installed on the support and get final product.

When OBU verified wireless tamper label, the maximum demand consumed current was at 70～80mA, and the standby current of OBU main part has only about 1mA.Calculate with the 1000mAh battery, if after main part is removed, owing to need constantly carry out the checking of wireless tamper label, can only standby about 14 hours.By starter gear of the present utility model, after the OBU main part is removed, the electric current of the hall device autophage that increases in the present embodiment only is several uA, and OBU did not need wireless tamper label to be verified before hall device detects useful signal again, can reduce the OBU standby power consumption greatly, effectively prolong the stand-by time of OBU, still calculate with the 11000mAh battery, but standby is about 1000 hours.

Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technology thereof, then the utility model also is intended to comprise these changes and modification interior.
