Abstract
The utility model discloses an electric locomotive speed measuring and alarming device. At least a magnet is uniformly arranged on the axle surface of an electric locomotive or on the inner side of a wheel hub, a transducer is arranged on the lower side of the electric locomotive, and each magnet is enabled to correspond to the transducer during the motion of the electric locomotive; a controller is arranged in the shed of the electric locomotive, and the lead wire of the transducer is connected to the corresponding interface of the controller. Speed signals are input during the operation of the electric locomotive, and the functions of speed display, mileage display, overspeed alarm, overspeed protection, voice alarm, etc. can be realized through the internal arithmetic of the controller, thereby a driver can master the real-time travel rate of the electric locomotive through the speed display of the speed measuring and alarming device, and can properly adjust the speed according to the speed, so as to know fairly well what to do. When the speed of the electric locomotive exceeds the set alarm value, the speed measuring and alarming device sends out an voice alarm to remind the driver to slow down; when the speed exceeds the set protective value, the protecting output node of the speed measuring and alarming device is cut off, so as to lower the speed of the electric locomotive, and then the original state can be recovered automatically.
Description
One, technical field
The utility model relates to a kind of test of mine electric locomotive travel speed, and sends the device of reporting to the police or protecting when reaching its setting speed.
Two, background technology
At present; the electric locomotive that under coal mine, uses; because of working environment special; all do not have the installation rate display device when dispatching from the factory, therefore, the travelling speed of electric locomotive can not directly show; the electric locomotive driver does not just hold accurately to the actual travel speed of locomotive yet; fully with own experience with feel to control the speed of a motor vehicle, like this, even at locomotive speed comparatively fast or under the situation of driving over the speed limit; also without any prompting and protection; bring threat to locomotive brake, cause braking distance longer, even surpass the requirement of " safety regulations in coal mine "; therefore; can not effectively guarantee transportation safety, cause some shipping accidents, even personal injury.
Three, summary of the invention
The technical problems to be solved in the utility model is: testing the speed to apply to install and putting of a kind of coal mine underground electric locomotive special use is provided; the travelling speed that can show locomotive in real time; show for the speed of a motor vehicle of an intuition of trainman; and when speed meets or exceeds its setting speed value; give a warning or protect; remind driver's Reduced Speed Now, guarantee traffic safety.
Solve the technical scheme that the utility model technical matters is adopted: on electric locomotive wheel shaft surface or inboard at least one magnetic patch of evenly installing of wheel hub, sensor is installed in below the locomotive, and makes locomotive each magnetic patch when motion all corresponding with sensor; Controller is installed in the bicycle shed of locomotive, and the lead-in wire of sensor is received on controller the corresponding interface.During the electric locomotive operation, the input speed signal by the controller internal arithmetic, realizes that the speed of a motor vehicle shows, mileage shows, overspeed alarming, overspeed protection, functions such as language alarm.Control circuit colleague technician all can design voluntarily, does not do detailed description at this.
Good effect of the present utility model is: the driver can show the travelling speed of grasping locomotive in real time by the speed of the alarm that tests the speed, and suitably regulates the speed of a motor vehicle according to the speed of a motor vehicle, accomplishes really to know what's what.When locomotive speed surpassed the alarming value of setting, the alarm that tests the speed just sent language alarm, and the prompting driver is slowed down; When the protection value of speed above setting, the protection output point of the alarm that tests the speed disconnects, and locomotive speed is descended, and then recovers original state automatically.
Four, description of drawings
Fig. 1: the scheme of installation of the utility model embodiment.
Five, embodiment
As shown in Figure 1, two magnetic patch 3 symmetries are embedded on the axletree 2, and sensor 4 adopts Hall elements, and sensor 4 is faced on the car body that magnetic patch 3 is fixed on the axletree top, at a distance of 4mm, the lead-in wire 5 of sensor 4 is received on the lead-in wire interface of controller between sensor 4 and the magnetic patch 3.
The wheel 1 of electric locomotive drives axletree 2 when moving and rotates, the moving magnetic patch 3 on all axletrees 2 of axletree 2 revolutions below sensor 4 through twice, sensor 4 is just delivered to rate signal controller and is carried out the circuit internal arithmetic, and the speed of a motor vehicle shows on display board simultaneously.When normal the driving, alarm is not reported to the police, when speed of displaying value during greater than the overspeed alarming value set, the utility model sends audio alert signal " hypervelocity " by loudspeaker, and alarm lamp is lighted simultaneously, reminds the driver to slow down, when speed is lower than alarming value, automatically terminate warning, alarm lamp goes out; When locomotive speed still increases, when surpassing the overspeed protection value, utility model is sent voice " overspeed protection " by loudspeaker; simultaneously, guard lamp is lighted, and the protection output contact disconnects (control end of the IGBT module of gating pulse speed governing locomotive); speed is recovered original state after reducing automatically.
