T unit.
Background technique
With wireless communication technique gradually be applied to industrial circle, using WiFi, Zigbee, LoRa, NB-IoT,
The radio network techniques such as WirelessHART, bluetooth acquire the vibration of rotating machinery and temperature data, Ke Yisui in factory
When understand equipment operating status, not only reduce the workload of manual inspection while reducing the maintenance cost of equipment.But
Existing wireless communications technology still has some shortcomings specifically in the application following four aspects:
One, battery explosion security risk
In petrochemical industry, the Flow Manufacturings such as coal chemical industry have the existing wireless vibration of strict requirements to sense for explosion-proof
Device is usually by accelerometer, wireless communication module, lithium battery, the composition such as shell.The vibrating sensor for including lithium battery passes through magnetic
It inhales or the mode of bolt is installed on rotating machinery.The operating temperature of lithium battery is generally in 0-40 degree, this is for some
The equipment for including high temperature liquid liquid, such as high-temperature heat-conductive oil pump or the equipment of failure, the temperature of sensor installation place
Up to a hundred degrees Celsius may be reached, temperature is transmitted to lithium battery by sensor outer housing, this is one for the stability of battery
Greatly test.Secondly percentage of batteries manufacturer is the energy density for promoting battery, relatively thin diaphragm has been used, so as to limited
More electric energy are stored in volume.The reduction of thickness increases the production difficulty of diaphragm, easily causes mass defect, prevents diaphragm from having
Effect isolation positive and negative anodes, and then cause the short circuit and explosion of battery.In the inflammable and explosive region of chemical industry, once battery catches fire or explosion
It will lead to the generation of accident or disaster, security risk caused by the intensive wireless sensor of quantity is ubiquitous.
Two, sensor battery capacity is less than normal
Since sensor is installed on mechanical equipment, volume is excessive to will increase installation difficulty and maintenance cost.So sensing
The size of device is usually the smaller the better, and lithium battery is in the limited space of sensor housing, can only select the lithium of smaller size smaller
Battery can also compress the capacity of battery in this way, although wireless sensor uses more energy-conservation of consumption reduction technology, hold after all
It measures limited.The battery of low capacity reduces the service life of wireless sensor, reduces the frequency of data acquisition, increases replacement
Battery or the workload of charging.
Since replacement battery is relatively complicated and sensor leakproofness is caused to decline, part manufacturer has developed disposal type and wirelessly passes
Sensor throws away the wireless sensor of only dead battery.Which increase the purchase cost of user, and practises strict economy with advocating
Theory is not inconsistent.
Three, sensor fault rate increases
Since to be internally integrated accelerometer, wireless communication module, lithium battery, vibration signal processing hard for wireless sensor
Part, the devices such as charging interface.This increases many components compared with common vibrating sensor, causes sensor internal electric
Road is complicated, and fault point is increased, and in duration high vibration, is easy to that circuit is caused to loosen, snaps even failure.
Four, received antenna signal is weak
It is too short for the transmission range of wireless signal since wireless sensor uses built-in antenna, increase gateway deployment
Quantity also increase the input cost of user.
