Description
Technical field
The utility model relates to a kind of base station cabinet fan pick-up unit, and the maintenance that is mainly used in cabinet fan detects.
Background technology
The base station cabinet fan is comprised of axial flow blower, control mainboard etc., and wherein axial flow blower is comprised of wind collecting unit, impeller, stator and diffusion barrel, meets national standard.Four control lines are arranged in master control borad, wherein two is the positive and negative wiring of 48v power supply, one is the rotation speed of the fan signal lines, one is rotation speed of the fan adjusting control signal wire, the voltage signal of external load is converted to frequency signal by special chip, rotate by amplifying drive motor, detection signal can detect the rotating speed of rotor by Hall element simultaneously, feed back to the control mainboard, carry out the adjusting of rotating speed, original control signal and detection signal are processed and are gathered by the base station master control borad, master control borad will judge that regulating fan opens according to the working condition of carrier frequency like this, play the great heat radiation effect to rack, original test fan will dispose carrier frequency to rack, data etc. just can be carried out fan and be detected.
When fan breaks down, existing detection mode: the fault fan is installed on the rack, carrier frequency is in normal operating conditions, judge the fan work state, the fan that damages is keeped in repair.The fan loading and unloading are cumbersome, make the carrier frequency normal configuration need of work long period, artificially judge the fan rotary state, cause easily erroneous judgement disconnected, repair relatively blindly, and the success ratio of reparation is low, and the cycle is long etc., and scrapping of generation is many; Need expensive human and material resources and time.
Summary of the invention
The utility model purpose is to solve the aforementioned problems in the prior, and a kind of convenient and swift, applied widely, base station cabinet fan pick-up unit that use cost is low is provided.
The utility model is for achieving the above object, the technological means that adopts is, a kind of base station cabinet fan pick-up unit comprises power transfer module, fan short circuit protection module, fan speed-regulating processing module, rotation speed of the fan display module, rotation speed of the fan control module, fan-status display module; Described power transfer module is exported to the fan short circuit protection module after external power source is changed; Described fan short circuit protection module connects the fan speed-regulating processing module; The rotation speed of the fan control module connects the fan speed-regulating processing module, is used for regulating rotation speed of the fan; Rotation speed of the fan display module input end connects fan speed-regulating processing module output terminal, is used for showing rotation speed of the fan; Fan-status display module input end connects fan speed-regulating processing module output terminal, is used for showing the fan work state.
Principle of work: power transfer module is external communication 220v, is converted to direct current 48v voltage in the mode of Switching Power Supply, and 2.5A output about power consumption 100W, consumes the 0.25A Current calculation with each fan, can be enough to band and carry 6 fans.Aanalogvoltage is controlled needed voltage and is produced by the fan speed-regulating processing module, the 0.7v that produces, 3.3v, 4.7v the corresponding control signal end of magnitude of voltage be fast, middling speed, at a slow speed, come Arbitrary cyclic to regulate each rotating speed of fan by the rotation speed of the fan control module, rotation speed of the fan shows that by the rotation speed of the fan display module people can be easy to judge quality.The fan-status display module is judged the duty of sensor and testing circuit part by detecting the rotating speed of fan electromotor, shows testing result.If be normal then the LED light of fan-status display module has demonstration, otherwise without demonstration, illustrate that the fan electromotor testing circuit partly damages, thereby play the alarm prompt effect.
The utility model beneficial effect is: convenient degree is high, cost is low, can adopt commercial power supply, only needs can finish in 5 minutes the test jobs of fan; It is few to detect the maintenance employment, and it is just passable only to need that fan is connected to this device, has promoted work efficiency, has saved the time, can avoid the damage to rack and original plate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model schematic block circuit diagram.
Among the figure: 1, power transfer module, 2, the fan short circuit protection module, 3, the fan speed-regulating processing module, 4, the rotation speed of the fan display module, 5, the rotation speed of the fan control module, 6, the fan-status display module.
Embodiment
A kind of base station cabinet fan pick-up unit as shown in Figure 1 comprises power transfer module 1, fan short circuit protection module 2, fan speed-regulating processing module 3, rotation speed of the fan display module 4, rotation speed of the fan control module 5, fan-status display module 6.Described power transfer module 1 is exported to fan short circuit protection module 2 after external power source is changed; Described fan short circuit protection module 2 connects fan speed-regulating processing module 3, and when the fan of short circuit accessed, fan short circuit protection module 2 can be protected in short-term, stops the output of DC voltage 48v.Rotation speed of the fan control module 5 connects fan speed-regulating processing module 3, is used for regulating rotation speed of the fan; Rotation speed of the fan display module 4 input ends connect fan speed-regulating processing module 3 output terminals, are used for showing rotation speed of the fan; Fan-status display module 6 input ends connect fan speed-regulating processing module 3 output terminals, are used for showing the fan work state.Fan speed-regulating processing module 3 output simulation control levels, and connect the control signal end of control of Fan Motor circuit to be measured realize the adjusting of fan different rotating speeds and open and stop by rotation speed of the fan control module 5.Fan detection signal on the fan control circuitry plate to be measured drawn add driving, make the duty of fan-status display module 6 indication fans.The display device of described rotation speed of the fan display module 4 and fan-status display module 6 is selected pilot lamp.
