Abstract
The utility model discloses a Nokia Flexi fan detecting device. The fan detecting device comprises a power circuit, a rotation speed control circuit, a fan switch, a current monitoring circuit, an indicator lamp display circuit and a fan connecting end. The power input end of the power circuit is connected with the 48 V DC input end, and the power output end of the power circuit is connected with the power input end of the rotation speed control circuit. The rotation speed control circuit is connected with the fan switch in a telecommunication mode. The power output end of the rotation speed control circuit is connected with the power input end of the current monitoring circuit. The power output end of the current monitoring circuit is connected with the power input end of the indicator lamp display circuit. The power output end of the indicator lamp display circuit is connected with the fan connecting end. According to the detecting device which gets rid of a Nokia Flexi fan unit in the Flexi carrier frequency unit maintaining test, fan maintaining and detecting are achieved conveniently, visually and rapidly; the Nokia Flexi fan detecting device has the advantages of being simple in structure, low in cost, stable in performance and long in service life.
Description
Technical field
The utility model relates to a kind of fan detection device, relates in particular to a kind of Flexi of Nokia fan detection device.
Background technique
The existing Flexi of Nokia fan maintainability test mode: fan unit packs carrier frequency test fan unit into and packs carrier frequency test into: be that the fan unit assembling of having keeped in repair is complete, and pack in Flexi carrier frequency unit, again carrier frequency unit is connected with main control unit, cable is all connected, open power switch on rack, main control unit is when starting, now fan is in full speed operation state, fan unit has 3 small fans, when indivedual fans or when all fan does not turn, being judged as fan unit has and does not turn fault; After main control unit starts, now rotating speed can reduce, and the rotating speed that tends towards stability, when indivedual fans or when all rotation speed of the fan does not reduce, is judged as fan and is not subject to controlling fault.Utilize carrier frequency unit to test, need constantly to start main control unit, carrier frequency unit is heavier, fan unit is carried out to dismounting repeatedly carrier frequency unit itself is had to injury, waste time and energy, be unfavorable for operation, efficiency is extremely low, and take base station testing station resource, and affect manufacturing efficiency, be unfavorable for cost-saving.
Model utility content
The purpose of this utility model provides a kind of Flexi of Nokia fan detection device with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises power circuit, rotating-speed control circuit, fan swicth, current monitoring circuit, tutorial light display circuit and fan connecting end, the power input of described power circuit is connected with 48VDC input end, the power output end of described power circuit is connected with the power input of described rotating-speed control circuit, described rotating-speed control circuit is connected with described fan swicth telecommunications, the power output end of described rotating-speed control circuit is connected with the power input of described current monitoring circuit, the power output end of described current monitoring circuit is connected with the power input of described tutorial light display circuit, the power output end of described tutorial light display circuit is connected with described fan connecting end.
Further, described fan connecting end comprises a plurality of, and its input end is all connected with the power output end of described tutorial light display circuit.
The beneficial effects of the utility model are:
The utility model departs from the detection device of the Flexi of the Nokia fan unit of Flexi carrier frequency unit maintainability test, realized convenience, intuitively, fan maintenance efficiently detects; The utlity model has simple in structure, cost is low, stable performance and working life longer advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Flexi of Nokia fan detection device described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises power circuit, rotating-speed control circuit, fan swicth, current monitoring circuit, tutorial light display circuit and fan connecting end, the power input of described power circuit is connected with 48VDC input end, the power output end of described power circuit is connected with the power input of described rotating-speed control circuit, described rotating-speed control circuit is connected with described fan swicth telecommunications, the power output end of described rotating-speed control circuit is connected with the power input of described current monitoring circuit, the power output end of described current monitoring circuit is connected with the power input of described tutorial light display circuit, described fan connecting end comprises a plurality of, its input end is all connected with the power output end of described tutorial light display circuit.
Working principle of the present utility model is as follows:
When the input end of detection device adds 48V DC electrical source, device interior power supply circuit is started working, and by voltage-drop loading to the fan unit of output terminal, according to the different adjustment fan brand switch of fan unit brand, current monitoring circuit can carry out current monitoring according to the inrush current of different brands fan, and the brand of Flexi fan has 2 kinds at present, and a kind of is Taida, be a SERVO, inrush current is respectively 0.14A and 0.08A.Gradually adjusting rotary speed control handle, now the electric current of rotating-speed control circuit can change according to adjusting knob, and when reaching starting fan electric current, 3 small fans of fan unit start to rotate simultaneously, and on panel, the tutorial light of corresponding 3 small fans all lights; Indivedual small fans do not rotate when reaching inrush current, and corresponding tutorial light can not light, and is judged as thus fan and does not turn fault, and the small fan that the tutorial light not working is corresponding removes maintenance; Continue adjusting rotary speed control handle, fan unit can rev up gradually according to continuing to increase of adjusting knob, when the rotating speed of indivedual small fans does not change or when abnormal, is judged as rotation speed of the fan and is not subject to controlling fault.
Those skilled in the art do not depart from essence of the present utility model and spirit, can there is various deformation scheme to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, within being all contained in interest field of the present utility model.
