Description
Technical field
The present invention relates to lithium battery bin library field of storage, are based especially on the lithium battery bin storing temperature of distributed optical fiber temperature measurement
Monitoring system.
Background technique
With the continuous development of China's industry, lithium battery is one of the direction of Future New Energy Source development, is with mobile phone at present
All kinds of consumer electronics, mobile power source, the new-energy automobile etc. represented all uses lithium battery device, with usage amount it is continuous on
It rises, the producer for producing battery also increasingly rises, and lithium battery warehouse kindling at the same time, the accident of lithium battery warehouse explosion are also frequent
Occur.Lithium battery be melted into during production and partial volume after be required to the turnover and storage of batch, lithium battery is still during this
Completion is not produced, the state of lithium battery and its unstable is easy to happen internal short-circuit or leakage problem, eventually leads to lithium battery
Local temperature increases phenomenon, if discovery will cause fire not in time or the accident of explosion occurs.And in traditional lithium battery bin
Be negligent of monitoring and management to battery temperature during depositary management reason, some producers then use relatively common fire-fighting class cigarette sense,
Warming sensing equipment carries out detection more of poor quality, and common warming sensor can not obtain temperature letter in temperature ascent stage early period
Breath, the ability alert when reaching 70 DEG C or more, cigarette propagated sensation sensor then just issues warning information when smog occurs, such
Equipment is unable to reach the purpose of primary prevention fire generation.And some such as 433MHz, zigbee of the mode using wireless temperature measurement,
Lora etc. will finally generate serious co-channel interference and face frequency and interfere, cause wirelessly to supervise since battery storage point is large number of
Measurement equipment communication failure.The sensing point delay that timesharing is sent is very serious, and the temperature for making battery store in a warehouse can not accurate real-time monitoring.
Therefore it provides a kind of battery compartment storing temperature based on distributed optical fiber temperature measurement monitors systems technology, the lithium battery of its storage is found
Temperature change state and the serious turnover lithium battery of temperature rise seem particularly significant, can effectively reduce the hair of fire and explosive incident
It is raw, timely improvement of finding the problem, to ensure the safety and people's security of the lives and property in battery warehouse.
But have not yet to see relevant report.
