The method for environmental monitoring and safety protection based on integrated electric energy meter verification according to claim 5, characterized in that: The safety protection measures include safety protection for personnel and safety protection measures inherent in the equipment; For the safety protection of the personnel, in terms of hardware facilities, protective covers are designed at each workstation, protective fences are designed and installed in the action area, safe sliding doors and cross-line ladders are designed in the areas inside the system that cannot be directly entered for inspection and maintenance, and each main test unit is equipped with an emergency stop switch and status indicator light; In terms of protective measures, a door-controlled switch is linked to the equipment power lock. Once the door-controlled switch is triggered, the equipment power is immediately cut off and the mechanical action stops immediately. All external metal parts that can be touched by personnel are reliably grounded.

7. The method for environmental monitoring and safety protection based on integrated electric energy meter verification according to claim 6, characterized in that: The safety protection measures of the equipment include: using a pneumatic mechanism, being provided with overpressure and underpressure protection devices to ensure that no abnormal action occurs in case of gas outage, overpressure or underpressure; The motor uses a thermal overload relay or motor protector to protect the motor and provide an alarm function through auxiliary contacts; The withstand voltage tester is equipped with leakage current detection and breakdown protection functions. It can automatically cut off the test voltage and give an alarm when an abnormality occurs. For parts that are prone to errors during the calibration process or require timely fault diagnosis, necessary video surveillance facilities are set up to automatically monitor the fault points and cooperate to achieve automatic alarm linkage to ensure the safe operation of single-phase lines.

8. A system using the integrated electric energy meter calibration environment monitoring and safety protection method according to any one of claims 1 to 7, characterized in that: It includes data acquisition module, safety protection module, fault diagnosis module, environment monitoring module, report generation and feedback module; The data acquisition module is responsible for real-time monitoring and acquisition of electrical parameters of the single-phase line core unit, while monitoring environmental factors. The acquired data will be used for subsequent performance analysis and fault diagnosis; The safety protection module checks and monitors various safety protection devices. When a safety hazard is found, the alarm system is automatically triggered and corresponding measures are taken to protect the inspection personnel and equipment. The fault diagnosis module analyzes the collected data, identifies potential faults and records fault history, and quickly determines the operating status of the equipment and provides maintenance suggestions by comparing historical data with real-time data; The environmental monitoring module is responsible for monitoring and recording various parameters of the operating environment, so that the impact of environmental conditions on equipment performance is within a controllable range, and combines environmental monitoring data with equipment performance for analysis to provide environmental adjustment suggestions; The report generation and feedback module is responsible for integrating the verification results, fault records and safety inspection results into a report to facilitate subsequent decision-making by inspection personnel and management.

9. A computer device comprising a memory and a processor, wherein the memory stores a computer program, wherein: When the processor executes the computer program, the steps of the method according to any one of claims 1 to 7 are implemented.

10. A computer-readable storage medium having a computer program stored thereon, characterized in that: When the computer program is executed by a processor, the steps of the method according to any one of claims 1 to 7 are implemented.
