How to structure and output the desired data

[muchengyang]

Seeking advice from experts, my requirement is to have the large model extract data according to the given JSON schema. I have tried many solutions and consulted a lot of information, but have not been able to achieve the desired results. I hope that experienced experts can share their experience with me
Here is my example
Prompt：
Your response should be in JSON format.
Do not include any explanations, only provide a RFC8259 compliant JSON response following this format without deviation.
Do not include markdown code blocks in your response.
Remove the ```json markdown from the output.
Here is the JSON Schema instance your output must adhere to:

    "$schema": " https://json-schema.org/draft/2020-12/schema ",
    "type": "object",
    "properties": {
        "WardName": {
            "type": "string"
        },
        "Bednumber": {
            "type": "string"
        },
        "Bodytemperature": {
            "type": "number"
        },
        "Pulse": {
            "type": "number"
        },
        "Systolicpressure": {
            "type": "number"
        },
        "Date": {
            "type": "string",
            "format": "date"
        },
        "Recordtime": {
            "type": "string",
            "format": "time"
        },
        "Diastolicbloodpressure": {
            "type": "number"
        }
    }
}`` 
1. 318 beds in the rehabilitation ward, pulse 80, systolic blood pressure 120, diastolic blood pressure 80, body temperature 37, tomorrow morning at 10am
2. Rehabilitation ward 318 beds, pulse rate 80, tomorrow morning at 10am
3. 318 beds
I hope that the inputs 1, 2, and 3 mentioned above can be accurately JSON. If no value is extracted, the assignment will be empty. Random assignment of large models is not allowed, and time can be calculated correctly
