Described cutter sweep 1 further comprises described processor 11, memory storage 12 and display screen 14.Described processor 11 is for carrying out other function softwares of described tension force early warning system 10 and the 1 interior installation of described cutter sweep.Described memory storage 12 can be the devices such as flash memory.Described memory storage 12 is for storing Various types of data, for example, and the information such as data of utilizing described tension force early warning system 10 to arrange, obtain.Described processor 11 can embed or be integrated in the PLC16 of described cutter sweep 1 with memory storage 12.
Described display screen 14 is for showing various information, for example, and early warning information, the visual informations such as tension value of detecting.Described display screen 14 can be the man-machine interface (HMI) on described cutter sweep 1.
In this better embodiment, described tension force early warning system 10 comprises a plurality of functional modules, respectively: module 100, signal acquisition module 101, computing module 102, comparison module 103 and warning module 104 are set.
The described module 100 that arranges, for standard tension value is set, and the default ratio based on this standard tension value in order to judge that whether tension force abnormal.Described standard tension value can carry out different settings and modification according to cut object.Described pre-set ratio is for judging that whether the tension signal of reception is abnormal, and for example, this pre-set ratio can be 5%, or adjusts according to different early warning demands.
As described above, when standard tension value after accomplishing the setting up, described tension controller 17 according to based on this standard tension value, calculate control parameter regulate the output parameter of described proportioning valve 18, make described proportioning valve 18 control described brake flange 19 according to the output parameter after this adjusting.Tension force by can change cut object to the control of described brake flange 19 is to reach default standard tension value.
The described module 100 that arranges, also for a plurality of Exception Types are set, and arranges the alarm mode of the different Exception Types of a plurality of correspondences.For example, described Exception Type can include, but are not limited to: tension force is bigger than normal and tension force is less than normal.
Described alarm mode includes, but are not limited to: the display screen 14 at described cutter sweep 1 shows default early warning information and/or utilizes this early warning information of loudspeaker (not being shown in Fig. 1) speech play on described cutter sweep 1 to realize early warning.Described early warning information, according to different Exception Types, includes, but are not limited to: when tension force is bigger than normal, point out this material to be cut to know from experience and rupture, when tension force is less than normal, prompting can produce the deviation that cuts to this cut object.
Described signal acquisition module 101, for gathering the tension signal of described a plurality of tension pick-up 13 detectings.
Described computing module 102, for the tension signal receiving is converted to digital signal, and determines corresponding tension value.For example, determined tension value can be the tension force sum that a plurality of tension pick-ups 13 detect, and can to the setting of tension pick-up 13, carry out different determining according to reality.
Described computing module 102, is further used for calculating the difference between this definite tension value and described standard tension value.
Described comparison module 103, for judging that when this difference is greater than or less than the pre-set ratio of this standard tension value tension force is abnormal, and definite Exception Type.When this difference is greater than the pre-set ratio of this standard tension value, described comparison module 103 determines that tension force is bigger than normal.When this difference is less than the pre-set ratio of this standard tension value, described comparison module 103 determines that tension force is less than normal.
As described above, when the every software and hardware in described cutter sweep 1 normally moves, the elements such as described tension controller 17, proportioning valve 18 and brake flange 19 can be realized the tension force of cut object is controlled according to default standard value.After said elements breaks down, can make tension force control cannot normally carry out, and therefore can cause tension force abnormal.
Described warning module 104, for utilizing with the corresponding alarm mode of determined Exception Type and carry out early warning when tension force is abnormal.As mentioned above, described warning module 104 can be by showing default early warning information and/or utilizing this early warning information of loudspeaker speech play on described cutter sweep 1 to realize relevant early warning on the display screen 14 at described cutter sweep 1.
For example, at Exception Type, be tension force when bigger than normal, described early warning information is pointed out this material to be cut to know from experience to rupture.At Exception Type, be tension force when less than normal, described early warning information prompting can produce the deviation that cuts to this cut object.
As shown in Figure 3, be the process flow diagram of the better embodiment of tension force method for early warning of the present invention.First, step S2, the described module 100 that arranges arranges standard tension value, and the default ratio based on this standard tension value in order to judge that whether tension force is abnormal.In addition, the described module 100 that arranges also arranges a plurality of Exception Types, and the alarm mode of the different Exception Types of a plurality of correspondences is set.For example, described Exception Type can include, but are not limited to: tension force is bigger than normal and tension force is less than normal.
Step S4, described signal acquisition module 101 gathers the tension signal of described a plurality of tension pick-up 13 detectings.
Step S6, described computing module 102 is converted to digital signal by the tension signal receiving, and determines corresponding tension value.
Step S8, the difference that described computing module 102 calculates between this definite tension value and described standard tension value.
Step S10, described comparison module 103 judges whether this difference is greater than or less than the pre-set ratio of this standard tension value.If this difference is not greater than or less than the pre-set ratio of this standard tension value, determine that tension force is normal, flow process is back to step S4.
If this difference is greater than or less than the pre-set ratio of this standard tension value, in step S12, described comparison module 103 judgement tension force are abnormal and determine Exception Type, and described warning module 104 utilizes with the corresponding alarm mode of determined Exception Type and carries out early warning, then, process ends.Described warning module 104 can be by showing default early warning information and/or utilizing this early warning information of loudspeaker speech play on described cutter sweep 1 to realize relevant early warning on the display screen 14 at described cutter sweep 1.
Above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to above better embodiment, those of ordinary skill in the art should be appreciated that to modify or to be equal to replacement technical scheme of the present invention and should not depart from the spirit and scope of technical solution of the present invention.
