Abstract

The utility model relates to a timing device specifically is steel ball roller -coaster time -recorder. The problem of current steel ball roller -coaster time -recorder is with high costs, the installation is inconvenient, the timing inaccuracy is solved. This steel ball roller -coaster time -recorder includes the casing, and including the singlechip, the signal input part of singlechip is connected with starting point switch and terminal switch in the casing, the starting point switch be two wires, the one end of these two wires links to each other with the singlechip, other end position relatively respectively the winding on two parallel single tracks of the steel ball starting point department of steel ball roller -coaster, terminal switch be two wires, the one end of these two wires links to each other with the singlechip, other end position relatively respectively the winding on two parallel single tracks of the steel ball terminal point department of steel ball roller -coaster, the singlechip still is connected with reset switch and charactron, and reset switch and charactron are placed in on the casing panel. The utility model discloses install simple, the easy accuracy that realizes, times, also be applicable to other devices of similar steel ball roller -coaster or the timing of product.

Description

Steel ball roller-coaster timer

Technical field

The utility model relates to a kind of time set, is specially steel ball roller-coaster timer.

Background technology

" steel ball roller-coaster " is one of competition project of middle school's Skill Competition, is called for short " roller-coaster ".Steel ball roller-coaster comprises bracing frame, the spiral track be made up of two parallel single tracks supporting or be fixed on bracing frame, steel ball is placed in (between two parallel single tracks) on track, and steel ball rolls down fast along track, realizes the simulate effect of true roller-coaster (the manned roller-coaster namely in recreation ground).The steel ball of steel ball roller-coaster under roll across in journey and need timing.Existing steel ball roller-coaster timer adopts infrared ray or magnetic induction, and install inconvenience, cost is higher, is not easy to popularize.Practise at ordinary times generally adopting manual time-keeping, out of true.Therefore, need to develop that a kind of cost is low, easy for installation, timing accurate steel ball roller-coaster timer.

Summary of the invention

The utility model solve existing steel ball roller-coaster timer cost high, install inconvenience, the coarse problem of timing, a kind of steel ball roller-coaster timer is provided.

The utility model adopts following technical scheme to realize: steel ball roller-coaster timer, comprises housing, comprise single-chip microcomputer in housing, and the signal input part of single-chip microcomputer is connected with starting point switch and limit switches; Described starting point switch is two wires, on two parallel single tracks at the steel ball starting point place that one end of these two wires is connected with single-chip microcomputer, other end position is relatively wrapped in steel ball roller-coaster respectively; Described limit switches are two wires, and one end of these two wires is connected with single-chip microcomputer, other end position is relatively wrapped on two parallel single tracks of the steel ball destination county of steel ball roller-coaster respectively; Single-chip microcomputer is also connected with reset switch and charactron, and reset switch and charactron are placed on case panel.During work, in steel ball drop process, successively contact with two wires be wrapped on two parallel single tracks of limit switches with starting point switch, each dropping process of steel ball, starting point switch and limit switches successively complete once process that is closed, that disconnect, thus transmit corresponding pulse signal to single-chip microcomputer, the time interval between two pulse signals is exactly time of steel ball drop.

The utility model make use of singlechip technology, have install simple, be easy to realize, the accurate feature of timing, timing can be accurate to after radix point 3; Numeral method is clear, clear, directly perceived, is conducive to the enjoyment that middle school student realize technical activity, strengthens competition confidence.This timer is also applicable to other device of similar steel ball roller-coaster or the timing of product.

Embodiment

Steel ball roller-coaster timer, comprises housing 1, comprises single-chip microcomputer in housing, and the signal input part of single-chip microcomputer is connected with starting point switch and limit switches; Described starting point switch is two wires 2, on two parallel single tracks at the steel ball starting point place that one end of these two wires is connected with single-chip microcomputer, other end position is relatively wrapped in steel ball roller-coaster respectively; Described limit switches are two wires, and one end of these two wires is connected with single-chip microcomputer, other end position is relatively wrapped on two parallel single tracks of the steel ball destination county of steel ball roller-coaster respectively; Single-chip microcomputer is also connected with reset switch and charactron, and reset switch and charactron are placed on case panel.During concrete enforcement, being provided with power supply (pond) in housing 1 for single-chip microcomputer powers, and the current supply circuit of power supply is serially connected with power switch.The following (see figure 4) of specific works process: closed electrical source switch, single-chip microcomputer powers on and brings into operation, and first carries out initialization, and then whether sweep starting point switch closes, receive closure signal, make numeral method zero, starting point switch is by the closed moment transferring disconnection and closure signal stopping to, and single-chip microcomputer starts timing and sweep stopping point switch, when single-chip microcomputer receives the closure signal of limit switches, timer expiration, and make numeral method timing time, complete timing course.Press reset switch, single-chip microcomputer, by initialization again, repeats said process, carries out timing course next time.As can be seen from above-mentioned specific works process, control software design needed for whole timing course single-chip microcomputer, be one simple, known by pulse and stop pulse as the timing program of external control signal, be that person of ordinary skill in the field is very easy to work out and obtains.The innovation of this timer focuses on the structure, textural of its hardware.

Claims
