Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of the another kind of embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferably embodiment of the present utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, this example provides a kind of pointer reometer of the gear that automatically switches, comprise: the first reometer, the second reometer, current detection module, input port and battery, described first reometer and the second reometer are connected to battery respectively by current detection module, and described input port is connected to the first reometer and the second reometer respectively by current detection module.
The range of range ratio second reometer of described first reometer of this example is little, and described current detection module also comprises MCU and comparing unit, and described input port is connected to MCU by comparing unit, and described MCU is connected with the second reometer with the first reometer respectively.
Described first reometer and the second reometer are the pointer reometer of different two standards of range, the size of current that described current detection module is inputted by current detecting chip detection input port, then compare by the comparer of comparing unit the range whether size of current be greater than the first reometer, if, then control the second reometer by MCU and enter duty, and control the first reometer and enter conducting state; If not, then control the first reometer by MCU and enter duty, and control the second reometer and enter conducting state, that is, by the comparer of current detection module inside, realize the automatic switchover gear of hardware mode.
Described comparing unit can realize the comparison between size of current and a certain concrete current value by the comparer of hardware very easily, this process compared is the comparison of hardware circuit, without the need to accurate current detecting chip and software input, cost is low, and reaction is quick and effective; And because the range of range ratio second reometer of the first reometer is little, the first reometer can be the small range ammeter of uA rank, so just make the precision of measurement very high, therefore on efficient product test basis, also assures that higher test mass.
And when telepilot product is tested, quiescent current is all within 20uA, working current is within 30mA, in prior art, slip-stick artist tests the quiescent current of telepilot and working current is tested by multimeter mostly, and is undertaken testing by multimeter and just need constantly to switch uA gear and mA gear, particularly troublesome, have impact on work efficiency to a great extent, and the serviceable life of multimeter is also short.
Therefore, the range of described first reometer of this example is preferably 0-50uA, and the range of described second reometer is preferably 0-50mA, when MCU detects that input current is less than 50uA, then and the first reometer work, the second reometer is conducting state; When MCU when test job circuit on reometer detects that output current is greater than 50uA, then automatically switch to the second electric current by hardware and normally work, the first reometer is conducting state.
Embodiment 2:
As shown in Figure 2, on the basis of embodiment 1, this example also comprises charging module and charging inlet, described battery is rechargeable battery, described first reometer is connected with rechargeable battery respectively by current detection module with the second reometer, and described rechargeable battery is connected with charging inlet by charging module.
Because the pointer reometer of described automatic switchover gear is mainly for the production of test link, so, its frequency used is necessarily very high, and the automatic switchover of this example to the detection of size of current and gear all needs extra consumption electric energy, so, if also adopt disposable battery as now traditional pointer reometer, the quantity using battery can be increased, so, not only cost adds, and also can aggravate the pollution of environment.
Therefore, this example is on the basis of embodiment 1, add charging module and charging inlet, realize powering to rechargeable battery by the charging module that cooperatively interacts and charging inlet, the demand of automatic switchover gear and current detecting can be met, no longer need repeatedly to change battery, further achieve the lifting of work efficiency, also reduce cost simultaneously, decrease the pollution of environment.
This routine described charging inlet is preferably USB charge port, and pointer reometer can be charged by USB, like this, can solve the problem of charge power supply well, just make the pointer reometer of automatic switchover gear can make completely portable.
Embodiment 3:
On the basis of embodiment 2, this routine described charging inlet comprises Wireless charging coil and wireless charging transmitter, and described wireless charging transmitter is connected with charging module by Wireless charging coil.Described wireless charging transmitter is the wireless charging base matched with Wireless charging coil, and the rechargeable battery of this example, by wireless realization charging, makes the pointer reometer of automatic switchover gear use more convenient and convenient.
This routine described wireless charging transmitter is provided with alerting signal receiving element and the alarm unit of series connection mutually, described charging inlet is provided with alerting signal transmitter unit, described alerting signal transmitter unit is connected with alerting signal receiving element, and described alarm unit comprises audible alarm unit and/or light warning unit.
When alerting signal receiving element receives the alerting signal that alerting signal transmitter unit launches, startup alarm unit is sounded and is reported to the police and/or light warning, as realized reporting to the police by hummer or LED, the alerting signal that described alerting signal can terminate for charging also can be the alerting signal finding wireless charging transmitter.
After rechargeable battery charging, described alerting signal transmitter unit sends the alerting signal that charging terminates; When the searching alerting signal that the searching button that alerting signal receiving element receives on charging inlet sends, described alarm unit sends warning.
Because the product of wireless charging is supporting, if can not find wireless charging transmitter, wireless charging will be made not realize, so, by arranging searching button on charging inlet, this searching button is for realizing the function found, in time can not find wireless charging transmitter, directly press the searching button on charging inlet, alerting signal receiving element receive find button send searching alerting signal time, described alarm unit sends warning, as sent ' dichloro-diphenyl-dichlorothane ' cry, thus find wireless charging transmitter.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
