1. Project Background

At present, with the rise of the manufacturing industry, the industrial pollution is also increasing. At present, the requirements for environmental monitoring of factories are becoming higher and higher. Many environmental problems caused by pollution cannot be measured with money. At present, the HSE system of factories is not sound, and improper management of industrial "three wastes" discharge often occurs; The environment in the factory is not effectively monitored, and the occupational health of workers cannot be guaranteed; Frequent leakage of explosive hazardous chemicals; The management of hazardous areas is not timely, and the potential safety hazards cannot be estimated; Improper management of electricity safety and a series of problems.

A medium-sized and heavy turbocharger manufacturer in Wuxi hopes to effectively solve the environmental, health and safety problems in the industrial production process. Wuxi Mantu Technology Co., Ltd. has created a set of HSE-IOT monitoring platform system based on HSE system, information technology and IoT technology, so as to carry out reasonable and standardized information and scientific management of plant environment, safety and health.

2. System architecture

The system collects the environment in the factory in real time through tilt sensor, liquid level sensor, PH, leakage monitoring sensor, grating and other environmental sensors, and uploads the data to the cloud server for analysis and processing through the 4G terminal gateway. The abnormal linkage alarm is displayed in real time, and the platform displays the GIS vector layout of the sensor in real time, and distinguishes between alarm information and processed alarm information; The platform supports big data display of environmental monitoring data and time period broken line chart display.

hardware configuration

Hardware equipment: control cabinet, intelligent gateway, audible and visual alarm, grating, inclination, liquid level, PH, turbidity, flame, leakage, water immersion sensor;

Working principle: collect the environment in the factory in real time through tilt sensor, liquid level sensor, PH, leakage monitoring sensor, grating and other environmental sensors, send the data to the cloud server through the intelligent gateway for storage, and analyze and process the data through HSE software;

Installation method: the sensor is installed at each monitoring point, and the 485 interface of the sensor is connected to the 4G gateway to achieve data transmission. 220V power supply is required on the site.

3. System functions

 Role management: The system supports user role assignment and management of permissions for role assignment;

 Project management: It supports the management of multiple project locations with the same account, facilitating remote centralized management;

 Device management: support the addition, deletion and modification of gateway, sensor and controller information;

 Alarm management: the system automatically detects equipment alarm, data overrun and other abnormal conditions, triggers the alarm mechanism immediately, gives audible and visual alarm prompts on site, and records alarm information on the platform.

 Data statistics: collect various parameters of scene equipment such as hazardous waste pool, grinder water tank and rainwater well in real time, and transmit them to the platform remotely through 4G. At the same time, the platform can remotely control and send instructions to the alarm; It also records the historical data and various alarm information of each device, and supports data export.

 Large screen display: real-time view of the real-time status of each environment and safety sensor, real-time display of alarm data when exceeding safety indicators, and support alarm notification of linkage equipment; GIS vector diagram shows the distribution of monitoring points and alarm prompts; Support real-time refreshing of alarm data, and display the processed alarms separately; Support the analysis and display of sensor parameter time period broken line chart.
