Description of drawings
Fig. 1 is the structural representation of the motor monitoring system of three-roller tandem rolling tube machine of the present invention.
The specific embodiment
The exemplary embodiments that embodies characteristic of the present invention and advantage will be described in detail in following explanation.Be understood that the present invention can have various variations on various embodiment, its neither departing from the scope of the present invention, and explanation wherein and appended accompanying drawing be the usefulness of being used as explanation in itself, but not in order to restriction the present invention.
Referring to shown in Figure 1 be the structural representation of the motor monitoring system of three-roller tandem rolling tube machine provided by the invention; This system comprises: organize thermistor 2, temperature polling instrument 3, PLC (Programmable Logic Controller, programmable logic controller (PLC)) equipment 4 and master control host computer 5 more.
This three-roller tandem rolling tube machine comprises a plurality of motors 1, and monitoring location on each motor 1 such as motor windings and motor bearings place all bury thermistor underground; Monitoring location on the motor 1 can add according to concrete needs, as also burying thermistor underground in other positions beyond bearing and the winding, more comprehensively motor is monitored.Every group of thermistor 2 on the motor 1 comprises at least two thermistor monomers; To guarantee to motor 1 monitoring accuracy and validity; This thermistor monomer can adopt PT100; The thermistor of burying underground on each motor 2 is connected with a temperature polling instrument 3, and temperature polling instrument 3 is converted into temperature value to the resistance of thermistor 2, thereby obtains the temperature information of thermistor 2.
After master control host computer 5 has obtained the temperature information of thermistor 2 of each motor 1; Just can monitor processing accordingly according to the temperature information and the real work situation of thermistor 2; Analyze the security of the motor of three-roller tandem rolling tube machine and also carry out handled, as monitor motor 1 temperaturing lifting abnormality and then give a warning or report to the police.For example: master control host computer 5 gives a warning when monitoring the temperature drift of motor 1; Go on-the-spot to confirm with the notification technique personnel, then remind the attendant between turn(a)round, motor 1 to be carried out necessary maintenance and maintenance when having than the high trend of other motor like certain motor 1 temperature.When the temperature that master control host computer 5 monitors motor 1 is higher than a preset safety value; Judge that then this motor 1 is dangerous and send warning; Need rolling completion just behind rolling steel pipe during warning, shut down and carry out scene and confirm and handle, 1 shutdown when avoiding rolling and steel pipe still rolls card in milling train.
Technical scheme of the present invention; For guaranteeing motor 1 monitoring accuracy and reliability to three-roller tandem rolling tube machine; At the monitoring location such as all pre-buried at least two the thermistor monomers of bearing or winding place of each motor 1, to guarantee monitoring accuracy, if when monitoring, find that the temperature difference of one group of thermistor monomer in the thermistor is bigger; Then judge it to be that certain thermistor monomer breaks down; Then the staff can go to the scene of motor 1 to confirm, searches and thermistor monomer that replacement is in time broken down, to guarantee motor 1 monitoring accuracy.Avoid causing normal motor is judged as unusually, and shutting down maintenance normal work of influence and production because the measure error of fault thermistor causes wrong report information.
In addition; Because the resistance of thermistor is to change with temperature; If connection cable 7 length between thermistor 2 and the temperature polling instrument 3 are long, then may have influence on thermometric accuracy, in order to overcome because of the stube cable 7 long measurement accuracys reductions that cause; Among the present invention the temperature polling instrument 3 of each motor 1 all is arranged at motor 1 next door overcoming this problem, as the length of guaranteeing the stube cable between temperature polling instrument 3 and the connected thermistor 2 is less than 50 meters.
Among the present invention, through Ethernet 8 transmission data, Ethernet is ripe industrial communication network between PLC equipment 4 and the master control host computer 5, strong interference immunity, can realize that big data quantity communication, real-time are also relatively good.The temperature information of PLC equipment 4 through 9 pairs of temperature polling instruments 3 of MODBUS interface module carries out after the interface data conversion, and the temperature information data after will changing through Ethernet 8 are sent to master control host computer 5.Through adopting the data between Ethernet 8 transmission PLC equipment 4 and the master control host computer 5, real time of data transmission and reliability can be guaranteed.
The motor monitoring system of three-roller tandem rolling tube machine of the present invention, the hardware cost of its increase is lower.One group of thermistor of this system adopts a plurality of thermistor monomers to measure motor temperatures, and every group of thermistor comprise two thermistor monomers at least, has improved the reliability to the motor monitoring thus.PLC equipment and master control host computer transfer of data adopt Ethernet, can effectively guarantee the quick transmission and the safety of data transmission of data.This system has realized motor is monitored accurately and effectively, helps the motor of three-roller tandem rolling tube machine is carried out care and maintenance.
