Description
Technical field
This utility model relates to a kind of detection device, more specifically, particularly relates to a kind of fuse on-line measuring device used for electric vehicle.
Background technology
Each electricity consumption device front end in electric automobile all can arrange fuse to protect electricity consumption device; fuse or works in the presence of a harsh environment after by long-term use and there will be catabiosis; when fuse is aged to a certain degree, its fusing performance arises that deviation, needs to be replaced before ageing.Current fuse behaviour in service is just changed after being typically in fuse blows, it is impossible to reach the effect of advance preventing, it is impossible to the effectively electricity consumption device in protection automobile；The phenomenon being also easy to screw loosening occur additionally, fuse works in the presence of a harsh environment, fuse screw loosening can cause spray arc, damage car internal unit, also can cause personal safety time serious.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, a kind of fuse on-line measuring device used for electric vehicle is provided, by the change in resistance of fuse, the aging of fuse and screw loosening phenomenon are carried out on-line checking, it is ensured that fuse normal is also used safely.
For achieving the above object, the technical solution adopted in the utility model is: a kind of fuse on-line measuring device used for electric vehicle, including resistance detection module, single-chip microcomputer, communication module, controller and alarm, realize data by PIN interface between described resistance detection module and single-chip microcomputer to transmit, in resistance detection module and single-chip microcomputer, there are two connection CANH and CANL representing signal height each connection, upper CANH with the CANL connection of resistance detection module and single-chip microcomputer accesses the input of communication module after being connected two-by-two, the outfan of communication module is connected with the input of controller, the outfan of controller connects alarm, resistance detection module is additionally provided with two when detection for just connecting fuse, the positive lead of negative pole and negative lead.
This utility model is by change (fluctuate or the steeply rise) situation of resistance detection module detection fuse resistance; judge whether fuse exists aging and that trip bolt is loosening phenomenon; can fuse the most complete aging before fuse is replaced, effectively protect the electricity consumption device of electric automobile；Caution signals can also be issued by when slight loosening occurs in trip bolt, prevent fuse from getting loose and produce spray arc and cause personal safety and property loss.

Detailed description of the invention
The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but is not intended that any restriction of the present utility model.
nullAs shown in Figure 1，The one fuse used for electric vehicle on-line measuring device that this utility model provides，Including resistance detection module 3、Single-chip microcomputer 4、Communication module 5、Controller 6 and alarm 7，Realize data by PIN interface between described resistance detection module 3 and single-chip microcomputer 4 to transmit，In resistance detection module 3 and single-chip microcomputer 4 each connect have two to represent the connection CANH(of signals height is high) and CANL(low)，Upper CANH with the CANL connection of resistance detection module 3 and single-chip microcomputer 4 accesses the input of communication module 5 after being connected two-by-two，The outfan of communication module 5 is connected with the input of controller 6，The outfan of controller 6 connects alarm 7，Resistance detection module 3 is additionally provided with two when detection for just connecting fuse 1、The positive lead 31 of negative pole and negative lead 32.
Used by this utility model, resistance detection module 3 is micro-phm level electric resistance detection module, and its sensitivity is high, it is possible to ensure the accuracy of measurement data；Single-chip microcomputer 4 used is STM32 single-chip microcomputer, and in single-chip microcomputer, programming has bsp driver, uses the standard resistance of fuse on-line monitoring and comparison first by Self-memory function record.
When using this utility model to carry out fuse ageing management, voltage-stabilizing constant-source is used to power to resistance detection module 3 and single-chip microcomputer 4, by resistance detection module 3 just, negative connecting line 31 and 32 correspondence is just being connected on fuse 1, on negative pole, the change in resistance situation of fuse 1 is measured by resistance detection module 3, and by measurement to data be transferred to single-chip microcomputer 4 by PIN interface, actual measurement data is contrasted by single-chip microcomputer 4 with standard resistance, analyse whether to exist extremely, and analysis result is sent to controller 6 by communication module 5, if the analysis result that single-chip microcomputer 4 draws exists abnormal, illustrate that detected fuse 1 exists catabiosis, then controller 6 sends control instruction startup alarm 7, alarm 7 is made to send alarm, prompting maintainer changes aging fuse in time.
When fastening installed by fuse, the contact resistance at fuse two ends is about the fuse piece resistance of fuse, and when trip bolt generation loosens or Tightening moment is inadequate, resistance can steeply rise.nullAccording to principles above，When whether the trip bolt 2 detecting fuse both sides exists loosening，Same employing voltage-stabilizing constant-source is powered to resistance detection module 3 and single-chip microcomputer 4，By resistance detection module 3 just、Negative connecting line 31 and 32 correspondence is just connected on、On negative trip bolt 2，The change in resistance situation at fuse 1 two ends is measured by resistance detection module 3，And by measurement to data be transferred to single-chip microcomputer 4 by PIN interface，Actual measurement data is contrasted by single-chip microcomputer 4 with standard resistance，Analyse whether to exist extremely，And analysis result is sent to controller 6 by communication module 5，If the analysis result that single-chip microcomputer 4 draws exists abnormal，Illustrate that detected trip bolt 2 exists the situation of loosening，Then controller 6 sends control instruction startup alarm 7，Alarm 7 is made to send alarm，Loosening trip bolt 2 is tightened by prompting maintainer in time.
This utility model detects change (fluctuate or the steeply rise) situation of fuse resistance by resistance detection module 3; judge whether fuse exists aging and that trip bolt is loosening phenomenon; can fuse the most complete aging before fuse is replaced, effectively protect the electricity consumption device of electric automobile；Caution signals can also be issued by when slight loosening occurs in trip bolt, prevent fuse from getting loose and produce spray arc and cause personal safety and property loss.
Certainly; this utility model can also have other various embodiments; in the case of without departing substantially from this utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and deformation according to this utility model, but these change accordingly and deformation all should belong to the scope of the claims appended by this utility model.
