and in response to the second deviation ratio being greater than or equal to the second preset deviation ratio and the engineering parameter not changing, determining that the base station antenna is blocked.
10. The automated monitoring method of claim 6, wherein the engineering parameters include latitude and longitude; the method further comprises the following steps:
acquiring the position information of the base station antenna according to the longitude and latitude;
acquiring an absolute value of a difference value between the position information and a preset position information threshold value;
judging whether the absolute value is greater than or equal to a preset difference threshold value;
and judging that the base station antenna shifts in response to the absolute value being greater than or equal to a preset difference threshold.
11. The automated monitoring method of claim 6, wherein the engineering parameters further comprise an inclination value; the method further comprises the following steps:
judging whether the inclination angle value is greater than or equal to a first preset inclination angle or less than or equal to a second preset inclination angle; wherein the first preset inclination angle is larger than the second preset inclination angle;
and judging that the inclination angle of the base station antenna is abnormal in response to the inclination angle value being greater than or equal to the first preset inclination angle or less than or equal to the second preset inclination angle.
