From above-mentioned, to description of the present utility model, compared with prior art, the utlity model has following beneficial effect:
1. the utility model by setting up reference signal line and signal lines in antenna element, and short circuit is carried out in their each one end, the other end that is simultaneously reference signal line by detection module provides a stable reference voltage, make the voltage of the signal lines other end have two states: 1) if antenna is not split, the short circuit loop between reference signal line and signal lines can keep, therefore, this voltage is consistent with reference voltage; 2) if antenna is split, the loop between reference signal line and signal lines is destroyed, and therefore, this voltage and reference voltage are not inconsistent.So, only need the voltage of the acquisition testing holding wire other end, and this voltage and reference voltage are compared, can judge that whether antenna element is split.Whole device circuit is simple in structure, and practicability and effectiveness.
2. in the utility model, the loop that short circuit forms mutually in antenna element, each one end of reference signal line and signal lines is independent of the original holding wire of described antenna element and signal ground, therefore can on the basis that does not affect original signal, carry out tamper detection.
Accompanying drawing explanation
Fig. 1 is the theory structure schematic diagram of a kind of mobile module antenna tamper checkout gear embodiment based on architecture advances of the present utility model.
Embodiment
Embodiment,
By embodiment, the utility model is further described below.
As shown in Figure 1, the utility model provides a kind of mobile module antenna tamper checkout gear based on architecture advances, comprises mobile unit unit 1 and antenna element 2;
Described mobile unit unit 1 comprises vehicle carried mobile phone module 11 and detection module 12, and described vehicle carried mobile phone module 11 connects respectively holding wire 21 and the signal ground 22 of described antenna element 2, for transmitting the original signal of vehicle-mounted mobile module 11;
Described antenna element 2 also comprises reference signal line 23 for setting reference voltage and the signal lines 24 for detection of voltage; Each one end of described reference signal line 23 and signal lines 24 is all fixed in described antenna element 2 and mutual short circuit, forms short circuit loop; Each other end of described reference signal line 23 and signal lines 24 is connected respectively described detection module 12, thereby when carrying out tamper and detect, detection module 12 provides reference voltage for reference signal line 23, and the voltage of acquisition testing holding wire 24;
In described detection module 12, be respectively used to have a default voltage difference between the initial voltage of two interfaces that connect reference signal line 23 and signal lines 24, when guaranteeing that each other end of described reference signal line 23 and signal lines 24 is destroyed in loop, magnitude of voltage is inconsistent;
The output of described detection module 12 connects vehicle carried mobile phone module 11, thereby when carrying out tamper detection, described detection module 12 is converted to by the voltage of the signal lines collecting 24 and reference voltage the level that vehicle carried mobile phone module 11 can receive, and the level after conversion is passed to vehicle carried mobile phone module 11, by vehicle carried mobile phone module 11, judge that whether antenna element 2 is split, and result of determination is recorded; Meanwhile, if conditions permit, vehicle carried mobile phone module 11 can also send to result of determination corresponding vehicle management control centre.
Preferred as one, the other end of described reference signal line 23 connects the preset reference voltage interface of described detection module 12, and the other end of described signal lines 24 connects the voltage detecting interface of described detection module 12; The reference voltage of the initial voltage of the voltage detecting interface of described detection module 12 and the preset reference voltage interface of described detection module 12 differs a default voltage difference.
Preferred as one, the loop that the mutual short circuit of each one end of described reference signal line 23 and signal lines 24 in antenna element 2 forms is independent of the original holding wire 21 of described antenna element 2 and signal ground 22, as shown in Figure 1, thus tamper is detected does not affect the transmission of original signal.
Based on above device, when antenna element 2 is normally not split, described reference signal line 23 can keep with the short circuit loop that signal lines 24 forms, therefore detection module 12 can detect that the voltage of described signal lines 24 other ends is consistent with the preset reference voltage that detection module 12 offers described reference signal line 23 other ends, or mutual voltage difference approaches 0 volt;
When antenna element 2 is split, described reference signal line 23 and/or signal lines 24 cause formed short circuit loop disconnection because being torn, therefore detection module 12 does not conform to the voltage that described signal lines 24 other ends detected with the preset reference voltage that detection module 12 offers described reference signal line 23 other ends, or mutual voltage difference approaches the default voltage difference of described detection module 12.
Based on above two kinds of situations, when detection module 12 is passed to vehicle carried mobile phone module 11 by the voltage collecting and reference voltage, vehicle carried mobile phone module 11 can according to two kinds of voltages unanimously whether, or according to the voltage difference size of two kinds of voltages, judge that whether antenna element 2 split.
Above-described embodiment is only used for further illustrating a kind of mobile module antenna tamper checkout gear based on architecture advances of the present utility model; but the utility model is not limited to embodiment; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all fall in the protection range of technical solutions of the utility model.
