Abstract
The utility model relates to a magnetic control sensor for measuring position, which is mainly used for measuring the position of an electric locomotive in a coal mine. The utility model comprises a magnet, a magnetizer, Hall switching elements, and a switch amplifying circuit. The magnet is arranged under or above an electric locomotive. The magnetizer is arranged on the air space above a lane or a foundation under a rail level. One or two Hall switching elements are arranged in the gap of the magnetizer. The pin of the Hall switching elements is connected with the switch amplifying circuit. The Hall switching elements can send out signals caused by the magnetic field of magnets in an electric locomotive when the electric locomotive reaches the position of a magnetizer, and the signals are magnified to cause the motion of a relay to output the signals. The magnetic control sensor has high sensitivity and reliable motion, which can suit the bad environments in coal mines.
Description
The utility model is a kind of sensor that is mainly used in the position finding of coal mine underground electric locomotive by magnetic field control.
The sensor that is used for the position finding of coal mine underground electric locomotive at present, formal manufacturer production mainly contain two kinds: a kind of is auxiliary traverse formula sensor, and another kind is an infrared ray sensor.
With in parallel with capacitor again after relay is connected, the other end of resistance is connected with auxiliary traverse auxiliary traverse formula sensor by resistance, and the other end of relay is connected with rail.Auxiliary traverse is fixed by bolts on the support by the embowment of band steel, with insulating clamp support is installed on the osculatory of powering into electric locomotive again.Do not have electricity on the auxiliary traverse at ordinary times, when the electric locomotive pantograph contacted with it, the voltage on the osculatory promptly was added on the relay coil actuating of relay by pantograph, auxiliary traverse after the resistance step-down.Auxiliary traverse is when sending electricity to relay, also to the capacitor charging, when the electric locomotive pantograph was left auxiliary traverse, capacitor discharged to relay through resistance, makes its slow putting.The shortcoming of auxiliary traverse formula sensor is that sensitivity is low, and slow motion is when the electric locomotive travelling speed is too fast, the tripping situation can occur once in a while, reason is that used here relay all is 110 volts of direct currents or 220 volts of relays, and coil turn is many, inductance is big, and the starting time is long, and sensitivity is low; Another shortcoming is that used auxiliary traverse is not only grown but also heavy, and general length is 1.0 meters～1.3 meters.
Infrared ray sensor in type approval test, the not high problem of reliability also occurred recently, and analyzing its reason is that humidity height and trickle cause owing to coal dust under the coal mine is big.Coal dust, particularly Chao Shi coal dust, might luminophor photoreceptor covers or the part cover, water has absorption to infrared ray.
Above-mentioned two kinds of sensors all work at the electric locomotive both direction of making a return journey, and can not be limited to just to work inoperatively at other direction in a certain direction, and this needs are arranged in some control system.
The purpose of this utility model provides a kind of highly sensitive, and reliable in action can adapt to that coal dust is big under the coal mine, temperature is high and rugged surroundings such as trickle arranged and can adapt to the position transducer of above-mentioned electric locomotive traffic direction requirement.
The utility model is realized with following method: adorn a support of being made by nonmagnetic substance above or below the electric locomotive centre position, adorn a magnetic field intensity big yoke shape electromagnet or permanent magnet in the centre position of support, adorn the yoke shape magnetic conductor in a crack with seam of making by soft magnetic material below perpendicular to the sky, tunnel of orbit centre or track cross level, one or two Hall switch element is adorned to magnetic direction in the inside, slit at magnetic conductor, and their three pins connect by the positive-negative-positive transistor, resistance, electric capacity, the switch amplifying circuit with time-delay release performance of compositions such as relay.The switch amplifying circuit adopts 6 volts～24 volts D.C. regulated power supplies.Because when the electric locomotive traffic direction changes, the magnetic direction of the magnet of being adorned on it also changes, and the Hall switch element has requirement to the polarity in magnetic field, be that lettering just can send signal facing to the south pole orientation in magnetic field, for satisfying the needs that all work at two traffic directions, solution of the present utility model is: in the slit of magnetic conductor, lettering facing to the lettering face adorn two Hall switch elements, their 1,2,3 three pin connects one to one, and is connected with the switch amplifying circuit more afterwards.A certain traffic direction just works for requiring to be limited to, and the utility model is only to adorn a Hall switch element in the slit of magnetic conductor, its lettering face right direction determine by the traffic direction of electric locomotive.In moving to, electric locomotive adorns the position of the magnetic conductor of two Hall switch elements, no matter the traffic direction of electric locomotive why, magnetic field of the magnet of adorning all can make one in two Hall switch elements to send signal on it, this signal is after the switch amplifying circuit amplifies, make the conducting of positive-negative-positive triode, the actuating of relay.At this moment, can also can export noble potential from the relay tip output signal from the collector of positive-negative-positive triode.Move to the position of only adorning the magnetic conductor of a Hall switch element in the slit when electric locomotive, only the traffic direction at electric locomotive is identical with set direction, that is to say that the Hall switch element just can send signal when the magnetic direction of electric locomotive upper magnet meets the polar requirement of Hall switch element.
Because magnet that the utility model adopts and magnetic conductor all are yoke shapes, the magnetic resistance of magnetic circuit is little, and magnetic field intensity is big in addition, thus highly sensitive, reliable in action; Because coal dust, humidity and trickle do not influence magnetic field, so can adapt to the rugged surroundings under the coal mine; Because Hall switch number of elements difference is installed in the magnetic conductor slit, so alternative two kinds of performances are arranged: a kind of is that another kind is to be only limited to a certain traffic direction just to work no matter the electric locomotive operation is which direction all works.
Below, the utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 is embodiment scheme of installation of the utility model.
Fig. 2 is another embodiment scheme of installation.
Fig. 3 is an embodiment magnetic circuit and circuit theory diagrams.
