Description
Technical field
The utility model belongs to automatic control technology field, in particular, provides a kind of contactor life monitoring device.
Background technology
In actual applications, contactor is the topworks of electrical system, and contactor has frequent movement, the characteristic of easily wearing and tearing, a lot of visual plant is not changed in time because of contactor device loss and great personal device damage is occurred, as the band-type brake contactor damage etc. of hoisting gear.
Therefore, we transform existing equipment, by the method to contactor action frequency record with add up serviceable life contactor under varying environment, in upper picture, display in real time also carries out the stable operation reminding support equipment after arrival replacing condition.
Summary of the invention
The purpose of this utility model is to provide a kind of contactor life monitoring device, before transformation, does not have the function of contactor service life supervision in system, changes the experience that contactor can only rely on maintainer.For the stable operation of support equipment, add contactor service life supervision function, evidence-based during to realize changing contactor.
The utility model comprises upper location supervisory HMI1, Siemens S7-400 PLC system 2, PLC digital output module 3, PLC digital quantity input module 4, contactor coil 5, contactor floating-point 6,24 volts of power supplys 7, ethernet line 8, core bus 9, signal wires 10.(Fig. 1).Core is Siemens S7-400 PLC system.Upper location supervisory HMI1 is connected by ethernet line with Siemens S7-400 PLC system 2, PLC digital output module 3 is connected with Siemens S7-400 PLC system 2 by core bus 9 with PLC digital quantity input module 4, and contactor coil 5 is connected with PLC digital output module 3 and PLC digital quantity input module 4 respectively by signal wire 10 with contactor floating-point 6.PLC digital output module 3 is connected with 24 volts of power supplys 7 by signal wire 10 with the power supply of PLC digital quantity input module 4.
The utility model has the advantage of, system is succinct, easy to use, safeguards simple, can accurately know the contactor life-span, can not have an impact to original system.
Accompanying drawing explanation
Fig. 1 is contactor service life supervision system connection layout.Wherein, upper location supervisory HMI1, Siemens S7-400 PLC system 2, PLC digital output module 3, PLC digital quantity input module 4, contactor coil 5, contactor floating-point 6,24 volts of power supplys 7, ethernet line 8, core bus 9, signal wire 10.
Fig. 2 is contactor service life supervision system process control flow chart.
Embodiment
The utility model comprises upper location supervisory HMI1, Siemens S7-400 PLC system 2, PLC digital output module 3, PLC digital quantity input module 4, contactor coil 5, contactor floating-point 6,24 volts of power supplys 7, ethernet line 8, core bus 9, signal wires 10.(Fig. 1).Core is Siemens S7-400 PLC system.Upper location supervisory HMI1 is connected by ethernet line with Siemens S7-400 PLC system 2, PLC digital output module 3 is connected with Siemens S7-400 PLC system 2 by core bus 9 with PLC digital quantity input module 4, and contactor coil 5 is connected with PLC digital output module 3 and PLC digital quantity input module 4 respectively by signal wire 10 with contactor floating-point 6.PLC digital output module 3 is connected with 24 volts of power supplys 7 by signal wire 10 with the power supply of PLC digital quantity input module 4.
Monitoring step of the present utility model is as follows:
1, the PLC system time is read;
2, contactor action is monitored;
3, judge that whether contactor action is normal;
If abnormal, record abnormal number of times, and determine whether caused by external condition, such as line virtual connection or contactor coil power supply disconnect, as then recovered outside for external cause and abnormal number of times being reset.
If the reason of contactor itself, then judge whether abnormal number of times reaches limits value, if reach limits value, report to the police and change contactor.
If 4 contactor actions are normal, then cycle count;
5, more whether reach this of value equipment life;
If reach life value, change, reset corresponding device access times also record replacing construction.
6, do not reach life value then to continue to perform tally function.
