The comprehensive detection method for mattress production according to claim 6, characterized in that: The step of determining whether the mattress to be tested passes the pressure distribution test based on the first pressure values ​​of the plurality of areas to be tested comprises: Acquiring second pressure values ​​of the plurality of to-be-tested areas after the target object changes from the first preset sleeping posture to the second preset sleeping posture, wherein a difference value between the first preset sleeping posture and the second preset sleeping posture is greater than a preset difference value; According to the obtained first pressure values ​​of the multiple areas to be tested, querying from a preset detection standard library first pressure value standard values ​​corresponding to the multiple areas to be tested that match the first preset sleeping posture; According to the acquired second pressure values ​​of the multiple areas to be tested, querying the preset detection standard library for second pressure value standard values ​​corresponding to the multiple areas to be tested that match the second preset sleeping posture; Based on the similarity between the first preset sleeping posture and the second preset sleeping posture, the first pressure value standard value, and the second pressure value standard value, it is determined whether the mattress to be tested passes the pressure distribution test.

8. The comprehensive detection method for mattress production according to claim 7, characterized in that: The determining whether the mattress to be tested passes the pressure distribution test based on the similarity between the first preset sleeping posture and the second preset sleeping posture, the first pressure value standard value, and the second pressure value standard value includes: calculating a similarity between the first preset sleeping posture and the second preset sleeping posture; Calculating a first pressure difference between the first pressure value and a first pressure standard value; Calculating a second pressure difference between the second pressure value and a second pressure standard value; Based on the similarity between the first preset sleeping posture and the second preset sleeping posture, the first pressure difference value, and the second pressure difference value, it is determined whether the mattress to be tested passes the pressure distribution test.

9. The comprehensive detection method for mattress production according to claim 4, characterized in that: The roller loading device comprises a roller loading upper beam, a roller lifting system, a roller loading lower beam and a roller; The first hardness value is greater than the fourth hardness value, and the second hardness value is greater than the third hardness value.
