The purpose of this utility model is to design a hazardous source early warning system that can be applied to solid waste factories, which can reliably and safely realize early warning management of hazardous sources. It mainly realizes two major functions: 1. Monitoring and early warning of the status of hazardous sources. , including but not limited to fire, humidity, etc.; 2. Control the personnel entering or approaching the dangerous sources of the solid waste plant, avoid the approach of idle personnel, and reduce potential safety hazards. The specific plan is as follows:

As shown in Figure 1, a hazard source early warning system for a solid waste plant includes a hazard source parameter monitoring module, a camera, a control unit, a hazard proximity module, and an alarm module. The input terminals of the control unit are respectively connected to the hazard source parameter monitoring module. module, hazard source proximity module, and camera; the output end of the control unit is connected to the alarm monitoring module.

The hazard source parameter monitoring module includes humidity sensors, pressure sensors, gas sensors, and temperature sensors, which are used to monitor humidity, air pressure, gas content, temperature and other parameters near hazard sources respectively to avoid hazardous materials in solid waste plants being affected by environmental parameters. By monitoring the temperature, humidity, air pressure, and proportion of toxic gases in the materials near the hazard source, danger signals can be discovered in time, thereby achieving the purpose of monitoring and early warning.

As the core central processor of this application, the control unit's main function is to collect and judge uploaded data and send out corresponding control signals, such as sending alarm signals and uploading data signals. Generally, controllers from the industrial field are used, such as Siemens S7 series. PLC controller, you can choose S7-200 and other model PLC controllers according to actual interface resources, data storage needs, etc. to realize the functions of the control unit.

The danger source proximity module includes a proximity switch and an electronic grating, which are used to detect people or objects approaching the danger source, provide timely notification to the approaching people or objects, and enable remote monitoring and alarming; the proximity switch can be set at the danger source. The appropriate location around the material is mainly to detect people approaching the dangerous material. The proximity signal is detected through the proximity switch and sent to the control unit. At the same time, in order to avoid missed detection, this application also sets up an electronic grating, which is arranged around the dangerous source. , used to monitor crossing the electronic grating into the dangerous area and send the monitoring signal to the control unit. It is also set around the material or in the channel before entering the material. Electronic grating emitters and electronic grating receivers are respectively set on both sides of the channel. They are both connected to the control unit. They are arranged so that the light emitted by the electronic grating emitter forms a detection Path, approaching the material through the channel will block the light and cause the receiving end to be unable to receive the signal. The control unit determines whether someone approaches or enters the factory where the material is located based on the received signal. The channel mentioned here can be a door, with settings on both sides of the door. This can be achieved with electronic gratings.

The alarm module of this application is mainly a component of monitoring and early warning.

The host computer can be connected to multiple large monitoring screens or monitoring PCs to monitor and view the video data in real time, or save it in the host computer. . The control unit determines whether the dangerous source materials in the factory are in a safe state at this time based on the data collected by the dangerous source parameter monitoring module such as temperature and humidity. If the temperature and humidity are abnormal, it is considered that there is a safety hazard and an early warning needs to be given. The control unit outputs control The signal is sent to the alarm module, thereby realizing local or remote early warning, reminding all staff to pay attention to safety, and realizing early warning. The control unit uses the hazard source proximity module to detect people or objects approaching the hazard source materials, and promptly sends out early warning signals. When it detects that someone is approaching, it can issue an early warning through the alarm module to avoid potential safety hazards caused by random approaches.

As shown in Figure 2, in another preferred embodiment of the present application, in order to achieve better management and early warning of hazardous materials in the factory, an intelligent access control system is set up for the factory.

The detected information of the person who opened the access control will be uploaded to the PC for storage and monitoring.

The hazard source system of this application can realize two functional modules: hazard source management function and hazard source early warning function. It has already positioned the hazard source information in the factory area and automatically monitored various data indicators in real time. If the hazard source monitoring value exceeds the set alarm The threshold will trigger an alarm. If there is an unauthorized intrusion into a dangerous isolation area or abnormal high temperature, toxic gas, humidity, or pressure, the alarm can be issued.
