The monitoring system has the benefits that the original wired sensing system is replaced with a wireless radio-frequency technology, the cost and work quantity can be saved, faults are easy to be eliminated and checked, and the maintenance is simple; the information is acquired in time, and staffs monitor the dynamic state of the coal yard without needing to stay beside a computer; and the wireless safety monitoring system of the coal yard is integrated independently, and a large system is formed by expansion of wireless communication and other relevant systems.
Description
Technical field
The utility model relates to a kind of coal yard safety monitoring system, specifically is a kind of coal yard Internet of Things supervisory system.Utilize less radio-frequency transmission network technology in the Internet of Things and sensor technology to realize the transmission of data in the supervisory system.
Background technology
Internet of Things (The Internet of things) is by information sensing equipment such as radio-frequency (RF) identification (RFID), infrared inductor, GPS, laser scanners, agreement by agreement, any article and Internet connection are got up, carry out message exchange and communication, to realize a kind of network of intelligent identification, location, tracking, monitoring and management.Internet of Things can be subdivided into sign, perception, processing and information and transmit four processes, and the gordian technique of each link is respectively RFID, sensor, intelligent chip and wireless-transmission network.
Coal yard is as the important place of coal storage, because spontaneous combustion and personnel's poisoning of coal often take place in the coal storage process, so coal storage safety is very important, coal yard must be installed the safety that safety monitoring system is used for ensureing coal storage.The coal yard monitoring system mainly is at temperature, toxic gas (CO), and inflammable gas (CH4), several factors such as naked light are monitored, thereby guarantee the safety of coal storage.To so far, what domestic most of coal yard monitoring system adopted all is traditional wire transmission mode, the signals collecting, communication, the control that are the monitoring system various piece are all finished these functions by cable, and the site environment more complicated of coal yard, the transmission range of coal yard and Master Control Room is also distant, so there is following shortcoming in wire transmission mode:
1. on-the-spot installation wiring complexity; Workload is big, length consuming time; The cost height.
2. various device breaks down and is difficult for investigation, safeguards also quite difficulty after finding out fault.
3. traditional wired wire laying mode upgrading is inconvenience very.
4. information is obtained untimelyly, and staff's maneuverability is poor.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the utility model provides a kind of coal yard Internet of Things supervisory system, utilizes less radio-frequency transmission network technology in the Internet of Things and sensor technology to realize the transmission and the control of data in the supervisory system.
The utility model is realized with following technical scheme: a kind of coal yard Internet of Things supervisory system, comprise part of data acquisition to the various unsafe factor image data in the coal yard, be connected collection terminal processor to the data conversion treatment of gathering with part of data acquisition, digital data transmission after the conversion is given the signal hop of control end controller, handle and export the control end controller and the connected host computer of control signal, described signal hop comprises and is connected the less radio-frequency transmitter module that is used to send the coal yard digital signal on the collection terminal processor, the less radio-frequency receiver module that is used to receive the coal yard digital signal of less radio-frequency transmitter module emission and the coal yard digital data transmission is given the control end controller; The control end controller is passed to host computer to the output data of handling by com port again, enters internet system.
Principle of work is: collect various switching value signals and 4-20mA simulating signal in the coal yard by part of data acquisition, the above-mentioned signal that collects is converted to digital signal by the collection terminal processor pass to the less radio-frequency transmitter module, wireless transmitter module is passed to the less radio-frequency receiver module to signal by wireless transmission, the less radio-frequency receiver module is passed to the control end controller to signal again, the control end controller is passed to host computer to data by com port again, enters internet system.
The beneficial effects of the utility model are: substitute original wired sensor-based system with wireless radio-frequency, advantage is:
1) the less radio-frequency sensor-based system need not wiring, can save a large amount of costs and quantities, and fault easily investigates, and safeguards simply, and upgrading only need be changed the wireless module upgrade software and get final product, so has very strong application and operability.
2) wireless transmitting system has been realized promptness that information is obtained and personnel's maneuverability, the staff need not always to monitor the dynamic of coal yard on the computer side, the wireless transport module of this system configuration, in coal yard during each sensor emission wireless data signal, system can pass through wireless transport module automatically, data message is in time sent to the wireless portable receiver that the staff carries, make the staff can take corresponding measure timely.
3) coal yard wireless security monitoring system is not only had a style of one's own, and also can form a big system again by spread radio communication and other related systems, and it is just passable only to need to match each other on software in expansion.So just the system integration for whole coal works provides convenience, helps the formation of whole Internet of Things network.
