[0059] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0060] Please refer to Figures 1 - 11 , the present invention provides the following technical solutions: A pre-employment integrated detection machine includes a main body 1 of the detection machine and an installation component 2 for fixing the main body 1 of the detection machine.

[0061] Further, by Figure 1 and Figure 2As shown in the figure, in this embodiment, there is a first mounting hole 211 on the mounting plate 21. The lifting plate 22 is slidably connected to the mounting plate 21, the flipping plate 23 is rotatably connected to the lifting plate 22, the inspection machine main body 1 is mounted on the flipping plate 23, the lifting power mechanism 24 is drivingly connected to the lifting plate 22 for driving the lifting plate 22 to move in the vertical direction, and the flipping power mechanism 25 is drivingly connected to the flipping plate 23 for driving the flipping plate 23 to flip.

[0205] Step 9: Blood Pressure Detection. Wrap the armband around the upper arm and keep it at the same height as the heart. The data is transmitted to the central control unit through RS232.

[0206] Parameter: Alarm threshold ≥140 / 90 mmHg.

[0207] Abnormal handling: If abnormal, prompt for re - detection or end the process.

[0208] Step 10: Health Declaration. The touch screen 3 displays the declaration questions, and the user selects the answers and submits them.

[0209] Step 11: Data Processing and End. All data is stored in the local eMMC / SD card and uploaded to the management platform through Wi - Fi / 4G / Ethernet.

[0210] All data (including time, personnel ID, detection value) is stored in the local eMMC / SD card.

[0211] Key Process Control Instructions:

[0212] 1. When the identity verification fails, automatically jump to the re - verification process;

[0213] 2. Alcohol detection anomaly triggers a dual-verification mechanism:

[0214] First over-limit → Voice warning + Countdown for retry;

[0215] Second over-limit → Directly lock and alarm.

[0216] 3. Abnormal body temperature detection directly aborts the process and alarms;

[0217] 4. Data storage adopts a dual-redundancy mechanism:

[0218] Local eMMC storage;

[0219] Real-time upload to cloud for backup;

[0220] 5. Each sensor module is equipped with a self-check mechanism:

[0221] Automatically runs a diagnostic program when starting up;

[0222] Triggers the display of error codes when abnormal.

[0223] Process optimization features:

[0224] 1. Parallel processing mechanism:

[0225] Voice broadcast is synchronized with screen display;

[0226] Data acquisition and algorithm calculation are overlapped and executed;

[0227] 2. Intelligent jump logic:

[0228] The configured and closed detection modules are automatically skipped;

[0229] Fast-track mode (certified personnel skip the notification link).

[0230] 3. Interruption recovery function:

[0231] Retains the last completed state after abnormal power-off;

[0232] When resuming inspection, you can choose to continue the unfinished items.

[0233] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
