Specific implementation mode
The present invention is described in detail with embodiment below in conjunction with the accompanying drawings.
Refering to fig. 1, the antenna for base station ice load test method of first embodiment of the invention, includes the following steps：
Step S1 freezes the ice face for forming thickness and being at least up to 10 centimetres on antenna for base station surface manually.Wherein, ice
The thickness that face is 10 centimetres is the minimum requirements of defined in national communication professional standard YD/T 1059-2004.
In conjunction with Fig. 2, in step sl, including：
Step S11 prepares to have water suction water storage performance and can wrap up the liquid storage component of the antenna for base station, wherein institute
The compressed thickness for stating liquid storage component is not less than 10 centimetres.The compressed thickness of the liquid storage component is not less than 10 centimetres so that passes through step
Liquid storage component after rapid S14 freezings can ensure to form over 10 centimetres of ice face on the antenna for base station surface, ensure to reach
The antenna for base station carries out the basic condition of ice load test, more true to nature, accurate to make every effort to subsequent test.Wherein, liquid storage component
Can be bat, sponge or the glass fabric that one side is equipped with waterproof waterproof cloth.
Step S12 sprays a certain amount of water to the liquid storage parts uniformity.When spraying water to liquid storage component, often by liquid storing part
The one of part waterproof lies in ground down.Further include following steps, referring specifically to Fig. 3 before step S12.
Step S1201 obtains the surface area of the antenna for base station.
Step S1202 calculates actual used water amount, wherein the formula is according to formula：Actual used water amount=antenna for base station
Area × ice thickness × ice proportion × K1, wherein K1=1.3.When specific calculating, the thickness of ice needs to select to be not less than
10 centimetres.Certainly, step S1202 can also split into two steps, i.e., first calculate theoretical water consumption, theoretical water consumption=base station
The proportion of thickness × ice of area × ice of antenna；Then actual used water amount is calculated again, actual used water amount=theory water consumption ×
K1.It in the step, needs to use COEFFICIENT K 1, is because part water may be lost during spray, or concentrated on and stored up with water
Liquid component some or several regions and cause water distribution uneven, thus need to use water more more than theoretical water consumption.
In a specific embodiment, actual used water amount can also be calculated by obtaining the surface area of liquid storage component, but the two compare and
It is more acurrate to be used as calculating actual used water amount using the surface area of antenna for base station for speech.

At least 4 hours and -20 DEG C constant temperature.The step can consolidate the surface temperature of antenna for base station, and ice face thickness is maintained to be basically unchanged.
Step S23 carries out sine vibration test according to relevant criterion within a certain period of time.Pass through in preferably 10 minutes by
Antenna for base station is installed to progress sinusoidal vibration test on shake table, influences test effect to avoid overlong time ablation.
Step S24 after vibration test, to relevant parameter detect or be arranged again, and to detecting or setting twice
Result is set to be compared.
Wherein, if the antenna for base station is electrical tilt antenna, in step S21- steps S24, the relevant parameter includes RCU
Calibration function, lower decline angle, mechanical tilt angle and graduated scale scale.If the antenna is non-electrical tilt antenna, step S23-
In step S24, relevant parameter includes mechanical tilt angle.Specifically by taking the antenna for base station is electrical tilt antenna as an example, i.e.,：
Step S21 is specially：After freezing, primary detection RCU calibration functions, check mark at setting lower decline angle function
Whether ruler scale value is identical as setting angle.
Step S23 is specially：It installs on antenna to shake table, measures mechanical angle of declination, record tilt angled down.Measure machinery
The instrument of angle of declination is bevel protractor.
Step S24 is specially：After vibration test, RCU calibration functions, setting lower decline angle function, inspection are detected again
Mechanical tilt angle is surveyed, and compares every testing result.And then it helps engineer to improve by the comparing result and improves the base station day
Line.
Step S25 removes the liquid storage component from the antenna for base station surface.
Step S26, restores certain time at room temperature, wherein the certain time is not less than 1 hour.
Step S27 carries out appearance detection.
Step S28 carries out electric performance test.
