[0033] If the absolute value of the first difference is greater than the first evaluation value and the actual temperature is greater than the standard temperature, the first recognition unit determines that the object type is a living thing;

[0034] The first absolute value of the difference is the absolute value of the difference between the actual temperature and the standard temperature.

[0035] Further, based on the fact that the object type is a living thing, the first recognition unit determines whether there is a danger of a living thing intruding according to the first actual position and the actual moving speed;

[0036] If the number of items satisfying a single determination condition in the first actual position and the actual moving speed is 0, the first recognition unit determines that there is no danger of biological intrusion;

[0042] If the number of items in the second actual position and the actual size that meet the single determination condition is not 0, the second recognition unit determines that there is a risk of metal impact;

[0043] If the absolute value of the fourth difference is greater than the preset fourth evaluation value and the actual size is greater than the preset standard size, it is determined that the actual size does not meet the single determination condition; if the absolute value of the fifth difference is greater than the second actual incrementable range and the second actual position distance is less than the first actual setting distance, it is determined that the second actual position meets the single determination condition;

[0044] The fourth difference absolute value is the absolute value of the difference between the actual size and the standard size; the fifth difference absolute value is the absolute value of the difference between the second actual position distance and the first actual setting distance; the second actual position distance is the distance between the second actual position and the actual occurrence coordinates.

[0045] Further, the judgment unit determines the actual danger level according to the recognition results of the first recognition unit and the second recognition unit;

[0046] If neither the danger of biological intrusion nor the danger of metal impact exists, the judgment unit determines that the actual danger level is level one;

[0047] If one of the danger of biological intrusion and the danger of metal impact exists, the judgment unit determines that the actual danger level is level 2;

[0048] If both the danger of biological intrusion and the danger of metal impact exist, the judgment unit determines that the actual danger level is level three.

[0049] Further, based on the fact that the actual danger level is level one, the alarm adjustment unit determines that the automatic protection mode is: only the second protection mechanism is turned on;

[0050] When the actual danger level is level 2, the alarm adjustment unit determines that the automatic protection mode is: both the first protection mechanism and the second protection mechanism are turned on;
