Description
A kind of temperature examining system
Technical field
The present invention relates to wireless sensor network monitoring technology field, more particularly to a kind of temperature monitoring system and method.Background of invention
In actual life, some objects are very sensitive to being raised and lowered for temperature such as dump, silo, brewery's fermentation vat, refuse landfill, petroleum storage tank.When the object temperature is too high or too low, it will cause larger environmental hazard and the loss of property.
For example, in the colliery place of production, power plant, steel plant, the place such as harbour, coal, which needs to concentrate, is deposited in special region storage.In stacking process, oxidation reaction occurs for coal and air contact in dump, and release heat.After occurring oxidation reaction, the temperature of dump will be raised.The rise of the temperature of dump accelerates the oxidation reaction speed of coal again.When temperature exceedes the self-ignition point of coal, spontaneous combustion will occur for dump.If self-ignition of coal pile can not be handled in time, it will produce serious fire, cause huge economic loss, simultaneously as burning is insufficient, the pernicious gas largely discharged can be polluted to environment.Particularly when spontaneous combustion occurs in transportation, it will jeopardize train, the means of transport such as steamer.
Thus need the temperature of thermally sensitive object to carry out effective monitoring, prevent because too high or too low for temperature cause damage.
By taking the temperature monitoring of dump as an example, there is following defect in existing temperature monitoring system：In the system that existing self-ignition of coal pile is monitored, the temperature monitoring point of monitoring dump temperature can pass through cable or optical fiber transmission of monitoring data.But because dump needs frequently to load and unload or mobile, monitoring point can not possibly immobilize, and the site operation difficulty of cable or optical fiber is big.In the system that existing self-ignition of coal pile is monitored, infrared thermal imaging probe or video probe can also be used to be monitored dump,
But it is due to that the probe can only monitor the surface temperature of dump, so when the surface temperature rise of discovery dump, or monitor smog, during the phenomenons such as flare, spontaneous combustion has occurred and that, can only just take the measures such as spontaneous combustion zone isolation, it is to avoid bigger loss.The content of the invention
In view of this, it is an object of the invention to provide a kind of system of temperature monitoring, it can realize and temperature monitoring is carried out to the diverse location of testee, the temperature change of testee is found in time.
To reach above-mentioned purpose, what technical scheme was specifically realized in：A kind of temperature monitoring system, the system is included：
One or more thermometric bar, the temperature value for measuring the position when being positioned over the relevant position of testee；
Temperature transmission node, the temperature value measured for one or more described thermometric bar of sampling, and the temperature value is sent to monitor terminal；
The monitor terminal, for managing the temperature value received, and is alerted when the temperature value reaches given threshold.
A kind of thermometric bar, including, body, one or more temperature-measuring parts；
The body, is cavity structure, and both sides set join domain respectively；
The join domain, for the thermometric bar to be connected with the second thermometric bar, forms the stock of an interior location for reaching the testee；
One or more of temperature-measuring parts are arranged in the cavity of the body, are respectively used to measure the temperature of the temperature-measuring part placement location testee.
As seen from the above technical solutions, the invention provides a kind of system of temperature monitoring, one or more temperature-measuring parts are all included in every thermometric bar, temperature survey can be carried out to the diverse location for being monitored object.It is possible to further which many thermometric bars are connected, the stock of a relevant position for reaching the testee is formed, can thus realize and solid is carried out to whole testee
Matrix form is monitored.In addition, as a result of wireless sensor network technology, the transmission of temperature value that need not be measured by temperature-measuring part is connected up, each monitoring point is independent, only connected by wireless sensor network mechanics of communication, conveniently monitoring point can be moved, increased, reduced.Brief Description Of Drawings
