How Face Recognition Pre-Work Alcohol Detection System Works

1. The complete system solves not the measurement, but the on-the-job safety closed loop

Independent alcohol detectors are able to output exhaled alcohol results, but it is difficult to automatically correlate employees, shifts, positions, and subsequent dispositions.For organizations such as buses, railways, mines, chemicals, manufacturing and construction, detection is often a link in the scheduling, attendance, pre-shift meetings, access control or departure process.

Therefore, the face recognition pre-job alcohol detection system needs to bind the living identity, personnel files, detection process, result determination, access control or attendance actions, and platform records to the same task.Only when the data can be returned to the enterprise business system can the management personnel confirm whether the person to be inspected has completed the detection, whether the abnormal person has been intercepted, and whether the subsequent retest and disposal are closed loop.

III. GB/T 21254-2017 and product design basis

The national standard solves the technical and performance requirements that the testing equipment needs to meet, and the pre-service management of the enterprise also requires personnel identity, business rules, system interfaces and abnormal handling.Together, the two form a complete scheme from "trustworthy test results" to "manageable process execution".

“Designed to Standards” does not equate to automatic certification.The scope of application, inspection conclusions and supporting materials of different models shall be subject to the official specifications, test reports, certificates or project delivery documents of the product.If the procurement or bidding project requires specific supporting documents, it is recommended to clearly verify during the selection stage.

V. Why has system docking become a necessary capability?

At present, most enterprises do not want to maintain a separate system from the business.Employee, organization, shift, and position information already exists in HR, scheduling, or production systems; there are also established processes for access control, attendance, departure, and safety incidents.If the alcohol testing equipment operates independently, it is necessary to repeatedly enter personnel, manually export records, and manually compare abnormalities, which not only increases the workload, but also easily generates data inconsistencies.

VI. What scenarios are HTTP, TCP, and MQTT suitable for?

乂点互联支持设备与客户平台通过 HTTP、TCP 和 MQTT 云中间件方式对接。最终选择并非越多越好，而应根据企业网络、实时性、数据量、安全边界和现有平台架构确定。实际接口字段、鉴权、重试、幂等、加密及离线补传机制需要在项目联调阶段确认。

VII. Three common ways of platform cooperation

VIII. How does data early warning form a closed loop of management?

Rather than simply popping up an "alcohol abnormality", the alert connects the abnormality object, detection value, device, time, responsible person, and treatment result.The system can pay attention to both the abnormal test results and the people who should be tested but have not completed them.

IX. How to reduce the risk of inspection, omission and data distortion?

1. Identity is tied to the detection process:Live faces, personnel files, test results and device times are written to the same record.
2. Anti-Generation Blowing Design:Optional anti-generation blowing function reduces the risk of blowing by other personnel after face examination.
3. Task Driven:Inspection tasks are generated by schedules, shifts, or positions, rather than recording only those who proactively come to the inspection.
4. Original Record Retention:Sampling failures, abnormalities, retesting, and final disposal leave marks, respectively, to avoid overwriting the first abnormal result.
5. Interface anti-duplication:Use unique record identification, timestamping, retry, and idempotent mechanisms to prevent duplication or loss of data.
6. Equipment Maintenance:Calibration, inspection and sensor maintenance according to product requirements to ensure long-term operating status.

X. How do different industries access business processes?

Bus, Rail & Logistics Driver

Obtain the person to be inspected from the scheduling or vehicle dispatching system, and complete the face and alcohol detection before departure.Check-in or entry into the departure process is allowed after normal; abnormal, late and missed checks are immediately notified to the fleet owner.

Mining, Energy & Chemicals

Configure testing tasks according to well entry, pre-shift meeting, key positions and different periods, associate with attendance, access control, EHS and personnel positioning system, and allow abnormal personnel to enter and retest or restrict access.

Industrial Manufacturing & Construction

Deploy terminals at fixed entrances or temporary booths and synchronize records to project management or labor systems in accordance with project, shift, contractor and high-risk post configuration testing rules.
