Abstract
The utility model discloses a two bus address coding modules, including control treater, coding disc and power module, the control treater passes through connection cable and outer locator and links to each other, and the coding disc changes epaxial chief editor code wheel and one from coding disc including setting up at meter pointer, chief editor's code wheel and all be provided with the count hole from the coding disc, the count hole be cyclic annular or trapezoidal, count hole around the centre of a circle evenly distributed of coding disc, the coaxial master gear that is provided with on chief editor's code wheel, the master gear and follow the coding disc on meshing from gear correspondence. The utility model discloses accessible control treater judges whether the two bus detector addresses of connecting designate the address unanimous with the coding disc, then carry out the addressing operation to it like the nonconformity, later get into the low -power consumption mode, do not influence the access control of host computer to two bus detectors. Lead, be provided with from the coding disc and count the hole, count the number of teeth that the pore pair should be suitable, can improve reading accuracy very evidently.
Description
Technical field
The utility model relates to a kind of coding module, particularly relates to a kind of double bus geocoding module.
Background technology
In the fire protection work of prior art, double bus detector adopts the mode of electronic code or mechanical coding to carry out the change write of address code to it, need during onsite application to do encoding operation respectively to the detector of different address, bring some inconvenience to real work, can not meet the requirement of people.
Utility model content
The purpose of this utility model is to provide a kind of double bus geocoding module, solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of double bus geocoding module, it is characterized in that, comprise control processor, code-wheel and power module, described control processor is connected with outer locator by connection cable, described code-wheel comprises and is arranged on chief editor's code-disc in gauge pointer rotating shaft and one from code-wheel, described chief editor's code-disc and be provided with counting hole from code-wheel, described counting hole is ring-type or trapezoidal, counting hole is uniformly distributed around the center of circle of code-wheel, chief editor code-disc on be coaxially arranged with main drive gear, described main drive gear with from should engage from gear mesh on code-wheel.
Further, the diameter of described chief editor's code-disc is 42mm-45mm.
Advantageous Effects of the present utility model is: core of the present utility model is embedded MCU control processor in module and connects into a total system with all parts.After complete machine energising enters duty, MCU control processor judges that whether the double bus probe address connected is consistent with code-wheel assigned address, as inconsistent, addressing operation carried out to it, enters low-power consumption mode afterwards, do not affect the access control of host computer to double bus detector.Master and slave code-wheel is provided with counting hole, the number of teeth that counting hole is corresponding suitable, clearly can improves reading accuracy.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is the schematic diagram of code-wheel gear structure.
Embodiment
By below to the description of embodiment; to more contribute to public understanding the utility model; but the restriction that the specific embodiment given by applicant can't be considered as technical solutions of the utility model, any definition to parts or technical characteristic change and/or to one-piece construction do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
Double bus geocoding module as depicted in figs. 1 and 2, comprise control processor, code-wheel and power module, control processor is connected with outer locator by connection cable, code-wheel comprises and is arranged on chief editor's code-disc 2 in gauge pointer rotating shaft 1 and one from code-wheel 3, also comprise the first annular counting hole 4 and the second ring counting hole 5, edit code-disc 2 and be provided with counting hole 6 from code-wheel 3, counting hole 6 is ring-type or trapezoidal, counting hole 6 is uniformly distributed around the center of circle of code-wheel, chief editor's code-disc 2 is coaxially arranged with main drive gear 7, main drive gear 7 with from engaging from gear 8 is corresponding on code-wheel 3, the diameter editing code-disc 2 is in the present embodiment 42mm-45mm, edit code-disc 2 in other embodiments and/or can be designed as other sizes from the diameter of code-wheel 3, the special value enumerated in embodiment is just in order to description technique scheme better, do not form the restriction to claims.Further improvement can also be made: inside the body of gear, be symmetrical arranged two draw-in grooves on the basis of above-described embodiment, make center of gravity and the axis coinciding of gear, centrifugal force can not be produced when High Rotation Speed, relative displacement is there is not between gear and axle, thus the wearing and tearing reduced between draw-in groove and axle, jump-ring slot inside gear installs jump ring, to gear play the role of positioning prevent work time gear produce skew.Embedded Control processor MCU is comprised in detector, code-wheel and power module, power module interconnects with above control processor MCU and code-wheel respectively and powers, and connection cable carries out as with host computer the connection device that communicates and power, and length freely can control according to rig-site utilization.
Principle of work of the present utility model is as follows: its major function of double bus protocol conversion module of the present utility model is completed by control processor MCU.Control processor MCU is an embedded computer control processor, be connected with double bus detector by peripheral interface, the address of double bus detector is read after entering mode of operation, and compare with the address that code-wheel is specified, as difference then addressing operation is carried out to detector after enter low-power consumption mode.Arrange the technology general knowledge that the peripheral interface of control processor and circuit belong to this area to those skilled in the art, those skilled in the art implement has no difficulty, therefore is not repeated herein.
Certainly; the utility model can also have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
