Description

Technical Field

[0001] This utility model relates to the field of safety monitoring of coal storage yards, and in particular to an intelligent safety monitoring device for coal storage yards in storage and transportation stations. Background Technology

[0002] A coal storage yard safety monitoring device is a supporting equipment for monitoring coal storage in a coal storage yard. During coal storage, the following safety hazards exist:

[0003] In coal storage yards, the main transportation equipment for coal entering the base is the belt conveyor. Due to its simple structure, low operating noise, and suitability for both bulk material and packaged goods transportation, it has been widely used in industrial fields such as coal storage yards. However, belt conveyors often experience slippage, deviation, overload, and belt breakage, which can lead to localized overheating and pose fire safety hazards.

[0004] Because coal in coal storage yards is generally stacked at certain intervals, it is affected by external weather conditions. As the storage time increases, the coal is exposed to the atmosphere for a long time, which will continuously undergo oxidation reactions, causing the temperature inside the coal pile to rise and even triggering internal combustion, resulting in huge economic losses and serious environmental pollution.

[0005] Among the two safety hazards mentioned above, real-time monitoring and early detection of spontaneous combustion risks in coal piles during coal storage are the key and challenging aspects of safety supervision in coal storage yards. Currently, the monitoring of spontaneous combustion risks in coal piles is still in the research and exploration stage. To date, the methods considered truly successful for detecting spontaneous combustion sources in coal include thermometry and gas analysis. Given the frequent transportation of coal in coal storage yards and the fluctuating storage time of coal piles with market demand, contact thermometry using numerous temperature sensors inside the coal pile is not feasible for temperature monitoring. While gas analysis can predict the temperature of high-temperature areas, it cannot accurately determine the location and rate of change of these areas, nor can it simultaneously measure multiple coal piles, thus limiting its application in temperature monitoring of coal piles in coal storage yards. Therefore, in practice, manual handheld thermometers are often used to measure the internal temperature of coal piles, identifying piles with rising temperatures by measuring multiple points on each pile. Due to the large volume of coal piles in coal storage yards, only 5-8 locations can be selected for temperature measurement on each surface of a single pile, with each measurement taking approximately 5 minutes, requiring at least 1 hour to measure a single pile. It is evident that this manual method suffers from numerous problems, including high workload, low efficiency, limited temperature measurement range, poor coverage, and low repeatability. However, managing large coal storage yards requires comprehensive temperature monitoring of all coal piles. This necessitates not only real-time monitoring of temperature changes on all sides of the coal piles to promptly identify potential spontaneous combustion hazards and implement safety measures to suppress their development, but also a comprehensive understanding of the overall temperature changes across multiple coal piles in the yard. By comparing the temperature rise of each pile longitudinally, high-risk piles can be prioritized for handling and transportation, eliminating the risk of spontaneous combustion as early as possible. Therefore, researching large-scale, real-time, effective, online, and non-contact coal pile temperature monitoring methods using advanced technologies and equipment is a crucial and urgent issue in coal storage management. It is also key to ensuring coal storage safety, preventing high-temperature spontaneous combustion, protecting the interests of both supply and demand sides, and safeguarding coal energy. To this end, we propose an intelligent coal storage yard safety monitoring device. Utility Model Content

It also adds gas detection and temperature probes to monitor the temperature from multiple angles and links with the fire protection system.

[0028] System Composition

[0029] CO, CH4, temperature, dust concentration, and smoke sensors are installed within the enclosed coal storage yard. These sensors are mounted on gas monitoring support brackets, and maintenance platforms are designed for each sensor to monitor combustible gases within the enclosed coal yard. The main control cabinet of the safety monitoring system is installed inside the coal yard, while the host computer (host computer) is installed in the coal conveying control room. Audible and visual alarms are installed in the coal conveying control room area, activating when measured parameters reach alarm values. Dust concentration detection and smoke detection systems should be compatible with the dust removal system, fire protection system, and automatic locator fire suppression system to meet relevant safety, fire protection, and dust removal regulations and actual needs, avoiding redundant equipment placement. Maintenance platforms should be designed for all sensors.

[0030] The safety monitoring system management platform is located in the coal conveying control room. The platform interacts with various temperature monitoring systems, CO, CH4, dust concentration sensors, and smoke sensors through data interfaces, and performs data reporting, analysis, and decision support in the background. The coal yard fuel safety information system software has key functions such as real-time data status visualization, abnormal alarms, system user management, and historical record query.

[0031] An online temperature monitoring device is installed in the enclosed coal yard: an infrared thermal imager is used for temperature measurement. This allows for complete monitoring of coal temperature changes in the coal yard. When the monitored temperature reaches a preset temperature threshold, an alarm is issued through the coal storage spontaneous combustion monitoring system software. The system software also displays the alarm temperature and the spatial location of the high temperature, prompting operators to take timely measures to prevent fire accidents.

[0032] The coal yard safety monitoring main control cabinet adopts a modular design, and can be equipped with communication cards, channel modules, relay modules, power supply modules, etc., as needed. It can monitor the system's concentration, alarms, faults, and other conditions in real time, and can use dedicated software to set and query various system parameters: setting system time, range (%LEL, PPM, %VOL), alarm type, and alarm concentration. The controller has an event logging function, recording alarms, faults, calibrations, warnings, etc. The channel modules can receive RS485 signals and can be connected to various devices such as combustible gas detectors, flame detectors, and smoke detectors. The channel modules can monitor the concentration, alarms, faults, and other conditions of external devices in real time and communicate with the communication card. The various output types of the channel modules can link multiple field external control devices, facilitating integration with the upper-level control system. Each channel module is relatively independent and can be locked individually; locking a specific area will not affect the normal operation of other areas. The power module can accept 24VDC and 220VAC external power and provide 24VDC power to external equipment in the field. The power module is equipped with a fuse and should also have a backup battery to maintain continuous system monitoring in the event of a power outage (depending on whether a UPS power supply is provided). Operating voltage: AC176V~AC264V (50Hz±1%). The explosion-proof rating of the coal yard safety monitoring main control cabinet should be no lower than ExdⅡCT6.

[0038] Ring Network Layout: The system ring network serves as the "highway" for all data transmission within the entire coal storage yard's spontaneous combustion environmental monitoring system. Therefore, the selection and topology of the ring network equipment are crucial. Ring network equipment mainly includes core switches, node switches, isolation gateways, firewalls, and fiber optic links. The network topology uses a gigabit ring topology for the backbone and a star topology for the branch networks.

[0039] Overall Layout: The overall system layout is to communicate with each monitoring point in the screening coal storage yard and the dome coal storage yard through the network, and transmit the on-site monitoring data to the dispatch control room in real time, so as to realize the dynamic monitoring of the system by personnel and the autonomous early warning of the system.

[0041] Design and implementation of the main interface

[0042] Upon entering the coal pile spontaneous combustion prevention monitoring system, the main interface is displayed. This interface primarily monitors the communication status between the system and the hardware, checks for data transmission failures from each temperature sensor, provides audible alarms, and accesses menu modules for different sub-interfaces (user login, real-time data query, historical data query for coal piles 1 / 2, real-time alarm, historical alarm, SMS alarm, and system exit). Clicking the menu module buttons on the main interface leads to different sub-interfaces, enabling various functions of the monitoring system. For example, clicking the real-time data query button accesses the real-time data query interface, allowing users to check the current temperature inside the coal pile.

[0043] User Login Module Design and Implementation

[0044] Click the "User Login" button on the main interface to enter the user login interface, as shown in the image below. User login involves three steps: identity verification, permission acquisition, and access control. This effectively ensures the safe operation of the low-power coal pile monitoring system. Identity verification guarantees the user's legitimate permissions. Different users obtain role information and corresponding permissions based on their identity identifiers. These permissions are pre-assigned by the administrator, resulting in different access permissions for different users after entering the system. The engineer station has full permissions and can perform secondary development of the system, such as adding temperature acquisition nodes. The operator station has partial permissions and cannot perform secondary development. Different operators are given different operating permissions, priority levels, and security zones.

[0045] Design and Implementation of Data Query Module

[0047] Real-time data query module

[0048] Clicking the "Real-time Data Query" button on the main interface will take you to the real-time data display interface, which reflects the temperature field inside the coal pile in real time, as shown in the image below. This interface enables real-time display and storage of data, allowing for real-time querying and tracking of the actual temperature inside the coal pile. It continuously monitors abnormal temperatures within the coal pile and immediately triggers an alarm upon detection. The real-time data query interface displays the temperature changes inside the coal pile monitored at each monitoring point, the power supply voltage of the temperature measuring device, and the strength of the signal emitted by the device. When the temperature measuring device malfunctions or the power supply voltage is too low or too high, the monitored data will flash continuously to facilitate maintenance. Clicking the "Temperature Correction" button corrects temperature errors, and clicking the "Upper Limit" or "Lower Limit" buttons sets the upper and lower alarm limits for the temperature.

[0049] Historical records query

[0050] Clicking the "Historical Records Query" button for either Coal Pile No. 1 or Coal Pile No. 2 on the main interface will take you to the historical data query interface for Coal Pile No. 1 / No. 2. This allows you to perform operations on the historical data of the coal piles. You can query historical data records for different dates for Coal Pile No. 1 / No. 2 as needed, and the historical data for the current day can be dynamically refreshed. Clicking different buttons on this interface allows you to operate on the data in the historical database.

You can also save and print the current historical data.

[0051] Design and implementation of alarm module

[0052] The design and implementation of the alarm module in the data monitoring center system is one of the core components of the entire system. The alarm module includes a real-time alarm module, an alarm query module, an SMS alarm module, and an audible alarm module. The real-time alarm module can display alarm information in real time and store it in the database; the alarm query interface allows users to query historical alarm information, facilitating the handling of coal with low calorific value due to repeated alarms; the SMS alarm can send alarm information to on-site personnel, reminding them to promptly handle coal with a tendency to spontaneous combustion; the audible alarm module complements the SMS alarm module, reducing the probability of spontaneous combustion in coal piles and minimizing the loss of coal calorific value.
