In industries with extremely high environmental requirements such as electronic chip manufacturing and pharmaceuticals, the concentration of dust particles in clean rooms directly affects product yield and production safety. Traditional manual sampling and detection not only have low efficiency and data lag, but are also susceptible to operational errors that can affect the results. This article will provide a detailed explanation of a setNetwork version high-precision cleanliness monitoring schemeWithout the need for complex wiring, it can achieve 24-hour online collection and data docking of clean room dust particles, providing practical reference for enterprise production environment control.

1、 Core requirements and pain points for cleanroom monitoring

There are strict standards for environmental cleanliness in scenarios such as clean workshops in electronic factories and sterile workshops in pharmaceutical factories (such as ISO14644-1)GMP standards）The traditional management model has many pain points:

1. Low efficiency of manual inspectionRegular handheld sampling devices are required to collect data at various points, which is time-consuming and labor-intensive, and cannot cover the entire monitoring period, resulting in regulatory gaps;

2. Poor data timelinessAfter sampling, it needs to be sent to the laboratory for analysis, but the results are delayed and the problem of particle concentration exceeding the standard cannot be detected in a timely manner;

3. Difficulty in linking dataManually recorded data cannot be directly integrated into the production management system, making it difficult to form visual analysis and traceability;

4. Point deployment is restrictedTraditional wired equipment wiring is cumbersome, and construction in some clean areas is difficult, making it difficult to flexibly expand monitoring points.

In response to the above issues,Online dust particle monitoring deviceIt can achieve automated and intelligent cleanliness control, perfectly adapting to the strict requirements of the electronics and pharmaceutical industries.

Real-time displays key environmental parameters such as particle count, temperature and humidity, and pressure difference, and the data accuracy meets industry standard requirements;

2. Online continuous monitoringSupport 24-hour uninterrupted collection, replace manual inspection, and achieve full time and full coverage cleanliness monitoring;

3. Convenient communication and dockingUsing Ethernet interface, supportingModbusProtocol, can directly interface with workshop SCADA systemMES systemOr third-party data platforms, to achieve automatic data uploading and centralized management;

4. Industrial grade stable and reliableThe equipment is adapted to clean room environments, has dust-proof and anti-interference capabilities, can operate stably for a long time, and reduces maintenance frequency;

5. Visual data displayEquipped with a high-definition display screen, it can intuitively view Real-time data and historical curves. In case of abnormalities, it can quickly alert through indicator lights and other means, making it easy for on-site personnel to handle in a timely manner.

3、 Core steps for implementing the plan

1. Point planning and deployment

·Based on the clean room area and production area division, determine monitoring points (such as key production workstations, ventilation openings, entrances, etc.) to ensure coverage of core control areas;

·The equipment adopts wall mounted/bracket installation method, which does not require complex wiring and can be directly connected to the workshop LAN through Ethernet cables. It is flexible to deploy and does not affect the airtightness of the clean room.

2. Equipment installation and debugging

·After fixing the device, connect the network cable and power supply, and confirm that the device starts normally;

·Configure device IP addresses and communication parameters to ensure interoperability with the enterprise management platform network;

·Calibrate the sampling flow and counting accuracy of the equipment to ensure that the monitoring data meets industry standards.

·

3. Platform integration and data management

·Connect device data to the enterprise production management system through Modbus Protocol to achieve centralized storage and visual display of data;

·Alarm thresholds can be set for parameters such as particle concentration, temperature and humidity, and pressure difference. In case of abnormalities, an automatic warning will be triggered to notify relevant personnel for timely handling;

·The platform automatically generates historical data reports and trend curves, supporting queries by time and location, providing data support for production environment optimization and compliance auditing.
