Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection domain of the present utility model.
First it should be noted that, the rubber roll operating pressure monitoring device that the utility model embodiment provides mainly is applicable to the rubber roller for industry that radius is 150 ~ 165mm.Mainly to be described the rubber roller for industry that paper carries out press polish process in paper technology in present specification, but this is not formed restriction of the present utility model.Below the rubber roll operating pressure monitoring device that the utility model embodiment provides is described in detail.
As shown in Figures 1 to 9, a kind of rubber roll operating pressure monitoring device, its concrete structure comprises: host computer 15, wireless receiving module 14, wireless transmitter module 13, single-chip microcomputer 12 and at least one group of pressure transducer 11; Outer surface or the inside covering glue-line 3 of rubber roll is located at by pressure transducer 11, and be electrically connected with single-chip microcomputer 12; Single-chip microcomputer 12 and wireless transmitter module 13 are all located on the roll neck 2 of rubber roll, and single-chip microcomputer 12 is electrically connected with wireless transmitter module 13; Wireless transmitter module 13 and wireless receiving module 14 carry out data transmission by radiowave; Wireless receiving module 14 is electrically connected with host computer 15;
Single-chip microcomputer 12 gathers the outer operating pressure data covering glue-line 3 of rubber roll by pressure transducer 11, and by wireless transmitter module 13, the operating pressure data covering glue-line 3 is outward sent to wireless receiving module 14; Wireless receiving module 14 receives the outer operating pressure data covering glue-line 3, and sends to host computer 15.
Wherein, this rubber roll operating pressure monitoring device can comprise following specific embodiments:
(1) often organize pressure transducer 11 and can comprise one for measuring the piezoelectric film sensor of the radial pressure of rubber roll and one for measuring the piezoresistive strain sheet of rubber roll circumference pressure; Rubber roll outer covers the surface of glue-line 3 or inside is provided with at least one pressure measurement point, and each pressure measurement point is provided with one group of pressure transducer 11, namely one for measuring the piezoelectric film sensor of the radial pressure of this pressure measurement point place rubber roll and one for measuring the piezoresistive strain sheet of this pressure measurement point place rubber roll circumference pressure.Piezoelectric film sensor and piezoresistive strain sheet are not be positioned over same pressure measurement point overlappingly, but take place side by side or leave the modes of emplacements such as certain interval.Size due to piezoelectric film sensor and piezoresistive strain sheet is far smaller than the size of rubber roller for industry, therefore for the volume of rubber roller for industry, the volume of piezoelectric film sensor and piezoresistive strain sheet is negligible, thus same pressure measurement point does not place a piezoelectric film sensor overlappingly and a piezoresistive strain sheet can be thought to carry out pressure detection to same pressure measurement point approx.
In actual applications, cover the surface of glue-line 3 or inside outward and can to distribute regularly N number of pressure measurement point, each pressure measurement point can be provided with one group of pressure transducer 11, i.e. total N group pressure transducer 11; And often organize pressure transducer 11 and can comprise a piezoelectric film sensor and a piezoresistive strain sheet, as long as therefore often organize in pressure transducer 11, gap and the modes of emplacement of piezoelectric film sensor and piezoresistive strain sheet are all consistent, piezoelectric film sensor and piezoresistive strain sheet so just can be made to form the array of pressure sensors of a rule distribution, and this contributes to monitoring more accurately the operating pressure of rubber roll diverse location and analyzing.
(2) when pressure transducer 11 be located at rubber roll outer cover the inside of glue-line 3 time, pressure transducer 11 is not more than 20mm apart from the surface covering glue-line 3 outward, if pressure transducer 11 is excessive with the surface distance covering glue-line 3 outward, so less pressure may can not be detected by pressure transducer 11, and this can be brought error to the monitoring of rubber roll operating pressure.
(3) roll neck 2 of rubber roll is provided with conducting ring 16; Pressure transducer 11 is electrically connected with single-chip microcomputer 12 by conducting ring 16.In actual applications, this conducting ring 16 can adopt model in prior art to be the conducting ring of SRM-12-06D.
(4) outside of single-chip microcomputer 12 is provided with metal explosion-proof shell; Single-chip microcomputer 12 is fixed on the roll neck 2 of rubber roll by this metal explosion-proof shell.Due to the working environment more complicated of rubber roller for industry, single-chip microcomputer 12 is arranged at the risk that the roll neck 2 of rubber roller for industry needs prevention work environment to bring, therefore single-chip microcomputer 12 is first fixed in metal explosion-proof shell, be fixed on the roll neck 2 of rubber roll by this metal explosion-proof shell again, this can improve the adaptive faculty of single-chip microcomputer 12 environment to external world.
(5) wireless transmitter module 13 and wireless receiving module 14 are the telecommunication circuits based on IEEE 802.15.4; In actual applications, wireless transmitter module 13 can adopt the radio transmitter based on nRF2401 rf chip in prior art; Wireless receiving module 14 can adopt the wireless receiving circuit based on nRF2401 rf chip in prior art.
(6) wireless receiving module 14 can be a wireless communication module independent of host computer 15, also can be the wireless communication module that host computer 15 inherently has.Wireless receiving module 14 can be connected by pci interface, PCI-E interface, USB interface or RS232 serial ports with host computer 15.
(7) single-chip microcomputer 12 preferably adopts intrinsic safety type STM32 single-chip microcomputer of the prior art; Intrinsic safety type is the abbreviation of essential safe type, it is the safest a kind of type of protection [of an electrical apparatus for explosive atmospheres of all type of protection [of an electrical apparatus for explosive atmospheres, no matter intrinsic safety type STM32 single-chip microcomputer is internal short-circuit or short circuit, the flammable explosive gas of surrounding environment all can not be caused to explode, this can make single-chip microcomputer 12 can adapt to the working environment of rubber roller for industry better, thus improves this rubber roll operating pressure monitoring device security of operation ability.
Particularly, because rubber roller for industry is in operational process, its radial direction and circumference are all under pressure, and therefore the course of work of this rubber roll operating pressure monitoring device is as follows: piezoelectric film sensor obtains the radial pressure value of rubber roll, and is converted into voltage value signal; Piezoresistive strain sheet obtains rubber roll circumference pressure value, is also converted into voltage value signal; These voltage value signals, after the process of single-chip microcomputer 12, send to wireless receiving module 14 by wireless transmitter module 13 with the form of radiowave; Wireless receiving module 14 receives these radiowaves, and parses the data of the radial pressure of rubber roll or the data of rubber roll circumference pressure, then sends to host computer 15, for monitoring, analysis, record, stores.
In addition, according to software programming technique of the prior art and mathematical modeling technology, specific program can be write on host computer 15, to realize carrying out automated data analysis to the data of the radial pressure of rubber roll and the data of rubber roll circumference pressure, and carry out different responses for different analysis results, such as: pressure inequality is reported to the police, data store the responses such as overflow alarm.
