Technical Field

The invention provides an electric locomotive with a brake early warning function, and belongs to the field of speed measuring devices.

Background

The underground mining 10-ton trolley locomotive is not provided with an online detecting instrument for the speed and the mileage of the trolley locomotive. In actual use, because the weight of a 4-cubic-mine-car is large when the 4-cubic-mine-car is removed, 8 4-cubic-mine-car is dragged to carry out transportation operation downhill in the normal work of a 10-ton trolley locomotive, and personnel cannot make correct judgment on the running speed and the braking distance in the matching operation process, so that personnel accidents are very easily caused.

Disclosure of Invention

The invention aims to provide an electric locomotive with a brake early warning function, which can display the speed of the electric locomotive and give an alarm before reaching a brake point.

The invention relates to an electric locomotive with a brake early warning function, which comprises an electric locomotive, wherein a magnetic signal receiver is arranged at the bottom of the electric locomotive, magnets are arranged on a wheel axle of the electric locomotive, the output end of the magnetic signal receiver is connected to a counting device in a cab of the electric locomotive, the output end of the counting device is connected to a controller, a laser ranging device is arranged at the locomotive of the electric locomotive, the output end of the laser ranging device is connected to the controller, and the output end of the controller is connected to an alarm.

When a wheel shaft rotates, the magnet approaches the signal receiver once, the magnetic signal receiver can send a high-level pulse, the technical device can record the number of pulses, namely the number of rotating circles of the wheel and send the number to the controller, the controller can multiply the number of the circles by the circumference of the wheel and obtain the speed by using the time, the braking distance of each vehicle speed can be recorded in the controller, the laser speed measuring device can send an analog signal to the controller when detecting that an object appears in the front of the vehicle within 100 meters, the controller compares the analog signal with the amount which is 1.5 times of the braking distance of the real-time vehicle speed, when the analog signal is small, the controller controls the alarm to send an alarm sound to remind a worker to brake at the first time and compare the amount with the amount of 1.5, so as to leave the reaction time for the worker, the controller adopts the existing industrial intelligent controller, and applying the existing arithmetic program and comparison program; the invention effectively reminds the workers and avoids the occurrence of dangerous accidents.

The electric locomotive with the brake early warning function is characterized in that a strobe light is arranged at the head of the electric locomotive and connected to a controller. After the controller receives the signal that laser rangefinder sent, can control the work of stroboscopic lamp simultaneously, make it send the stroboscopic, if the obstacle is people, then can be timely remind.

The electric locomotive with the brake early warning function is provided with an electronic brake system, and the output end of a controller is connected to one end of the operating end of the electronic brake system in parallel. After the controller receives the signal that laser rangefinder sent, send the signal of telecommunication back to the operation end of electron braking system, make it brake, guaranteed to brake at the very first time, improved the security.

Compared with the prior art, the invention has the beneficial effects that:

when a wheel shaft rotates, the magnet approaches the signal receiver once, the magnetic signal receiver can send a high-level pulse, the technical device can record the number of pulses, namely the number of rotating circles of the wheel and send the number to the controller, the controller can multiply the number of the circles by the circumference of the wheel and obtain the speed by using the time, the braking distance of each vehicle speed can be recorded in the controller, the laser speed measuring device can send an analog signal to the controller when detecting that an object appears in the front of the vehicle within 100 meters, the controller compares the analog signal with the amount which is 1.5 times of the braking distance of the real-time vehicle speed, when the analog signal is small, the controller controls the alarm to send an alarm sound to remind a worker to brake at the first time and compare the amount with the amount of 1.5, so as to leave the reaction time for the worker, the controller adopts the existing industrial intelligent controller, and applying the existing arithmetic program and comparison program; the invention effectively reminds the workers and avoids the occurrence of dangerous accidents.

The stroboscopic lamp, after the signal that laser rangefinder sent is received to the controller, can control stroboscopic lamp work simultaneously, make it send the stroboscopic, if the obstacle is people, then can be timely remind.

The electronic brake system sends an electric signal back to the operating end of the electronic brake system after the controller receives the signal sent by the laser ranging device, so that the electronic brake system brakes, the brake is guaranteed to be carried out at the first time, and the safety is improved.
