5. The method of claim 2, wherein, After the target psychological stress type information is determined according to the plurality of target keyword information, the method further comprises: Acquiring trigger quantity information corresponding to each target psychological stress type information; For a specified target psychological stress type information, a first real-time physical sign data set information and a last real-time physical sign data set information are acquired, wherein the specified target psychological stress type information is used to describe a target psychological stress type information with a trigger quantity greater than 1; According to the pre-test average heart rate information and real-time heart rate information corresponding to the first real-time physical sign data set information, a first heart rate fluctuation value information is generated, and according to the pre-test average heart rate information and real-time heart rate information corresponding to the last real-time physical sign data set information, a last heart rate fluctuation value information is generated; The first heart rate fluctuation value information and the last heart rate fluctuation value information are compared; If the last heart rate fluctuation value information is greater than or equal to the first heart rate fluctuation value information, a severe stress identification information is generated.

6. A psychological stress assessment system based on a plurality of physiological parameters, characterized in that, The system comprises: A real-time physical sign data set information acquisition module is configured to acquire real-time physical sign data set information of a target user in response to an answer starting instruction, wherein the real-time physical sign data set information comprises real-time heart rate information, real-time blood pressure information, real-time skin conductivity information, and real-time respiratory rate information; A target keyword information determination module is configured to determine target keyword information according to the real-time physical sign data set information and preset regular physical sign data set information; A target psychological stress type information determination module is configured to determine target psychological stress type information according to a plurality of target keyword information.

7. The system of claim 6, wherein, The target psychological stress type information determination module comprises: A matching keyword information determination sub-module is configured to determine matching keyword information according to the target keyword information based on a preset word-disease association database, wherein the word-disease association database stores a plurality of second candidate keyword information and psychological stress type information corresponding to each second candidate keyword information, and the matching keyword information is used to describe a second candidate keyword information identical to the target keyword information; A target psychological stress type information determination sub-module is configured to determine the psychological stress type information corresponding to the matching keyword information as the target psychological stress type information based on the word-disease association database.

8. A terminal device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that, The computer program is executed by the processor to implement the steps of the method according to any one of claims 1 to 5.

9. A computer-readable storage medium storing a computer program, the computer program comprising instructions that, when executed by a computer, cause the computer to perform the method of any one of claims 1 to 8. The computer program is executed by the processor to implement the steps of the method according to any one of claims 1 to 5.
