Abstract
The utility aims to solve the technical problem of providing a graduated scale unloading vehicle displacement recognition system, thereby realizing real-time position detection of three unloading vehicles. The graduated scale unloading vehicle displacement recognition system comprises a ground subsystem, a vehicle-mounted subsystem and a graduated scale subsystem. During the process of unloading materials on a loading belt conveyor to a storage bin, the special graduated scale detects the displacement of a mobile device by adopting an electromagnetic induction principle, carries out precise positioning on the unloading vehicles, and transmits position signals to the ground subsystem; the ground subsystem transmits the position signals to a field upper computer; the field upper computer gives out relevant moving, stopping and unloading instructions to the vehicle-mounted subsystem according to the current positions of the unloading vehicles; and the requirement of mixing different materials in pre-ironmaking process of steel production is satisfied through reciprocating motion of the unloading vehicles in the track direction.
Description
Technical field
The utility model relates to a kind of conveying of loose unpacked material, relates in particular to a kind of graduated scale dummy car displacement recognition system.
Background technology
Mine before iron in system, raw material, sintering, pelletizing, coking, ironmaking and port and pier all can be used dump car and carry out discharging, and dummy car is realized the Multipoint Uniform cloth by Accurate Position Control, improves thus capacity, create economic benefit.In steel manufacture process, the iron prosomite need to be mixed difference material kind, the degree of accuracy of feed bin cloth affects steel quality and benefit, control and can science to reach product quality requirement before iron by the efficiently and accurately robotization to dummy car, and can improve productivity effect, improve operating personnel's working environment.
The most original control at present is that operating personnel move with dolly, with manually controlling dump car, realizes the discharging to feed bin, and the post operation personnel observe the material level of each feed bin by human eye, as required dolly is reached to rational feed bin discharging.Secondly to control of dump car, be by each feed bin place mounting limit switch mostly, the position signalling of the several points that utilize it to provide carries out Long-distance Control in operation room; Dolly arrival target position in storehouse and the judgement of changing storehouse are based on to the indicator signal of the position in storehouse signal lamp on operator's console: for example 1#-12# just arranges 12 corresponding position indicators in totally 12 storehouses on the operator's console panel.The signal of pilot lamp is that each side, storehouse by the scene fills one or more approach switchs (or limit switch) and obtains.When dolly during through the approach switch at position in storehouse place or limit switch, inductive switching to one signal, give Central Control Room, thereby the pilot lamp in corresponding storehouse is bright, operating personnel just know that dolly has arrived the target storehouse, by stopping knob, carry out discharging, when the material level signal designation storehouse of Central Control Room completely after operating personnel control dolly and continue operation to the left or to the right, until arrive corresponding target storehouse, the cloth that stops again after signal lamp is bright, reach the purpose of changing storehouse with this.
The limit switch that traditional this mode is used there will be following problem: first is easily malfunctioning, and the principle of work of approach switch or limit switch has determined that its reliability is not good.Secondly while brake due to dolly, " slip car " phenomenon of generation, stop being forbidden.So once dolly can not accurately be parked in installed limit switch scope (slip car), none brightens all signal lamps on the operator's console of Central Control Room, so also just occurred we said " dolly position loss ", middle control personnel do not know where dolly is on earth, at this moment just need to confirm to inform middle control behind little truck position in the scene of sending someone, middle control could continue the operation trolley travelling and arrive target location.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of graduated scale dummy car displacement recognition system, solves the real time position detection that three dummy cars move simultaneously.This utility model comprises ground subsystem, onboard subsystem, graduated scale subsystem.At the material by the charging belt machine, be discharged in the process in feed bin, special-purpose graduated scale adopts electromagnetic induction principle to detect the displacement of mobile device, dummy car is accurately located, and send position signalling to ground subsystem, ground subsystem is passed to position signalling on-the-spot host computer again, on-the-spot host computer sends to onboard subsystem according to the dummy car current location and relevantly moves, stops, the instruction of discharging, to-and-fro movement by dump car in orbital direction, realize the needs that in iron and steel production iron prosomite, difference material kind are mixed.
The technical solution of the utility model is: described ground subsystem comprises Switching Power Supply, scale analyser, lead-in wire converter, gateway, described onboard subsystem comprises scale instrument for generating, vernier pointer, and the scale instrument for generating is connected and gives vernier pointer generation electromagnetic signal with the outer vernier pointer of car body; The noncontact parallel with graduated scale of described vernier pointer installed, and determines the positional value of current indication by the mode with the graduated scale electromagnetic coupled; Described graduated scale subsystem comprises special-purpose graduated scale, CN case, EN case, automatic regulator; Described special-purpose graduated scale consists of flexible rubber sheathing material and the inner heart yearn of working out according to the Gray code rule of flat, be arranged on along mobile vehicle orbit single side, perhaps along running orbit, lay on the ground, or install on fence column in orbit.Graduated scale is connected with ground regulator cubicle input end, receives the electromagnetic signal of graduated scale, and output terminal is connected with on-the-spot host computer; Described graduated scale automatic regulator provides precompression, pre-pressure of the spring to be used for making up the stroke caused by the material temperature coefficient when being used for the tensioning steel wire, reach the purpose that improves positioning precision.
The beneficial effects of the utility model are.
1, detect in real time the dummy car current location, i.e. position in storehouse of living in (groove position) identification.
2, Multipoint Uniform cloth (blanking), improve the capacity utilization factor.
3, accurately operation, Optimizing Flow, reduce the probability of manually makeing mistakes.
4, prevent wrong storehouse batch mixing, depart from the generation of discharge port accident.
5, coordinate with level-sensing device according to technique, realize Long-distance Control, semi-automatic, full automatic working.
6, realize the computer management of production run, remote monitoring, production status storage inquiry.
7, the healthy and personal safety of protection workman, increase work efficiency and production management level.
8, extend the serviceable life of dummy car.
9, position interlocking is controlled and is prevented that blanking from falling through or the position that oversteps the extreme limit bumps, derailment accident.
