Embodiment 1

[0034] as attached figure 1 As shown, the coal yard temperature monitoring system includes a temperature data acquisition module 2 for collecting coal pile temperature data, a data transmission and reception module 3 for wirelessly transmitting and receiving the collected data, and a data processing module 4 for processing the received data , a spontaneous combustion control module 5 that performs spontaneous combustion control on the coal pile according to the temperature data of the coal pile.

[0035] as attached figure 2 As shown, a plurality of temperature nodes 21 in the temperature data acquisition module 2 are connected to the main pipeline 23 through a tee 22. For the convenience of installation, the main pipeline 23 provided with sensors is connected through a flexible joint 25, and the top pipeline at the knuckle at the top of the retaining wall 11 24 (a metal hose) is connected with the main pipeline 23 through a self-fixing joint 26, and the multi-section main p...

Embodiment 2

[0038] Based on the method of the above-mentioned embodiment one monitoring system, the temperature data acquisition module 2 is used to detect the temperature information in the coal storage yard 1 in real time, and the data transmitting and receiving module 3 is based on ZigBee wireless communication technology, and the nodes communicating with each other send their own coordinate positions and temperature information Sent to the central node, the central node transmits the temperature data through the GPRS network to the remote server host computer software (data processing module 4) through the Zigbee to GPRS module, and the server-side host computer software processes the coal pile temperature data. The upper computer software has the overall layout of the coal yard and the layout of the measuring points, giving the operator an intuitive experience. The software can display the cloud map of the temperature of the entire coal yard in real time, and can also display the chang...

Abstract

The invention relates to a system and a method for monitoring the spontaneous combustion in a round coal yard. The system and the method involve a round enclosed type coal storage yard, and are characterized by comprising: temperature data acquisition modules uniformly installed along the height direction of the blocking walls of the coal storage yard; a data emitting-receiving module used to transmit data and instructions among the temperature data acquisition modules and a data processing module; the data processing module configured to process the received data and to monitor the temperature in the coal storage yard; and a spontaneous combustion control module configured to prevent the coal piles from spontaneous combustion. With the system and the method, it is possible to dynamically present the coal heat loss and to quantize the inventory coal's efficiency. The association of the temperature data with the spontaneous combustion control steps means that when the coal pile temperatures exceed a certain temperature, the spontaneous combustion control steps work automatically, therefore, making the operation people unnecessary.

Description

technical field [0001] The invention relates to a self-ignition monitoring system and method for a circular coal yard, which is a set of temperature monitoring system, which mainly monitors and controls the temperature of the coal pile in the circular coal yard to ensure that the temperature of the coal pile is at a safe and controllable level. Within the range, prevent spontaneous combustion in coal yards. Background technique [0002] With the improvement of environmental protection requirements, coal storage yards have gradually developed from open to closed. Especially for newly built large-scale thermal power plants, coal yards are mostly closed dry coal sheds and closed circular coal storage yards. The diameter of the circular closed coal storage yard is generally 80-120m, the height of the coal pile is 15-35m, the height of the coal retaining wall is 15-25m, and the coal shed is a steel frame structure. [0003] In order to ensure the continuous operation of the powe...
