Description

TECHNICAL FIELD

[0001] The utility model relates to a field of shunting locomotive technology, especially a locomotive anti-collision earth bank information control device. BACKGROUND

[0002] At present, the passive point type information mode is adopted for the control of the anti-collision earth bank device of the shunting locomotive in China. The magnetic field pulse signal is generated by the magnetic field of the permanent magnet on the ground through the installation of the machine sensing coil on the locomotive according to the speed of the locomotive, the signal is sent into the locomotive monitor through the information conversion, thereby controlling the locomotive and preventing the locomotive from colliding with the earth bank of the terminal line.

[0003] The above technology utilizes the magnetic force lines generated by the receiving coil cutting the ground point type device (ferrite permanent magnet magnetic steel) to form a voltage pulse signal, the signal is processed through the conversion device to be converted into a signal that can be received by the locomotive monitoring device, thereby realizing the monitoring of the running state of the locomotive. When the receiving coil on the locomotive passes above the ground point type device (such as ferrite permanent magnet magnetic steel), the receiving coil will cut the magnetic force lines generated by the magnetic steel. This process will form a voltage pulse signal, the voltage amplitude of the pulse signal is proportional to the speed of the receiving coil cutting the magnetic force lines (i.e. the speed of the vehicle), and the width of the pulse signal is inversely proportional to the speed of the vehicle. Subsequently, the pulse signal will be converted through the information conversion device (box) to be converted into a signal that can be received by the locomotive monitoring device. The LKJ locomotive monitoring device (after software and hardware modification) can identify the information, thereby realizing the monitoring of the running state of the locomotive and the corresponding anti-collision earth bank control.

[0004] Since the pulse width and amplitude of the pulse signal are controlled by the speed of the locomotive, when the speed is high, the pulse width is too narrow, and under the condition of the frequency response lag of the point type information converter, the signal transmitted to the locomotive monitor is too weak and the locomotive monitor cannot be started and controlled; when the speed is too low, the amplitude is not enough, the point type information converter has no signal sent to the locomotive monitor, causing the failure of the control.

[0005] The current solution: first, the driver is required to control the speed (13-18 Km / h) to pass through the "ground sensor" to ensure the pulse width of the pulse signal to start and control the monitor. Second, the minimum height of the locomotive machine sensing coil and the "ground sensor" is adjusted as much as possible to obtain the amplitude of the pulse signal to ensure the control and parking of the monitor. The first point is not realistic in the actual shunting work, and the second point is limited by the height of the locomotive obstacle remover, the minimum height of the machine sensing coil and the "ground sensor" can only be adjusted to 110mm, and the effect is not good.

[0054] The output pin of the first voltage comparator 61 is provided with a first pull-up resistor 641, and the output pin of the second voltage comparator 62 is provided with a second pull-up resistor 642.

[0055] The first input pin of the first voltage comparator 61 is connected to GND through a third resistor 633, and the first input pin of the second voltage comparator 62 is connected to GND through a fourth resistor 634.

[0056] The first voltage comparator 61 and the second voltage comparator 62 constitute two-way voltage signal comparison amplification circuits, the first voltage comparator 61 is forward, and the second voltage comparator 62 is backward, wherein the first resistor 631 and the second resistor 632 divide the voltage and input the reference voltage to the second input pins of the first voltage comparator 61 and the second voltage comparator 62 in opposite phases, and the sensitivity of the magnetic induction of the inductor coil is determined by adjusting the second resistor 632.

[0058] As shown in Figure 3 The output control circuit 5 includes a double time base integrated chip 51, a first time base module and a second time base module, and the double time base integrated chip 51 is an NE556 chip.

[0060] The emitter of the second triode 522 is connected to GND, the collector of the second triode 522 is electrically connected to the sixth pin of the double time base integrated chip 51, and the collector of the second triode 522 is connected to VCC through a sixth resistor 542, the base of the second triode 522 is connected to GND through a third capacitor 533, and the base of the second triode 522 is electrically connected to the logic output controller 3;

[0061] The positive pole of the first capacitor 531 is electrically connected to the first pin and the second pin of the double time base integrated chip 51, and the positive pole of the first capacitor 531 is connected to VCC through a seventh resistor 543, and the negative pole of the first capacitor 531 is connected to GND;

[0062] One end of the second capacitor 532 is electrically connected with the third pin of the double time base integrated chip 51, and the other end is connected with GND.

[0063] The double time base integrated chip 51, the sixth resistor 542, the first capacitor 531 and the second capacitor 532 form a monostable mode, and the delay time of the circuit is determined by the sixth resistor 542 and the first capacitor 531. The second transistor 522, the sixth pin of the double time base integrated chip 51, the sixth resistor 542 and the second capacitor 532 form a trigger end. The fifth pin of the double time base integrated chip 51 and the fifth resistor 541 form a delay-off output, which drives the relay. When there is no trigger signal input to the second transistor 522, the fifth pin of the double time base integrated chip 51 outputs a low level, and the relay K1 does not work. When the pulse signal from the sensor is injected into the base of the second transistor 522 through the logic output controller 3, the fifth pin of the double time base integrated chip 51 changes from "0" to "1", the coil of the relay is powered, the relay outputs a rising edge voltage, and after about 1.1 times the resistance value of the sixth resistor 542 times the capacitance value of the first capacitor 531, the output end changes from "1" to "0", and a stable pulse voltage signal is transmitted to the locomotive monitor 4.

[0064] The second time base module includes a fourth capacitor 534, a fifth capacitor 535 and a third transistor 523,

[0065] The positive electrode of the fourth capacitor 534 is connected with VCC, the negative electrode of the fourth capacitor 534 is electrically connected with the twelfth pin and the eighth pin of the double time base integrated chip 51, and the negative electrode of the fourth capacitor 534 is connected with GND through the eighth resistor 544, the eighth resistor 544 is connected in parallel with a diode 55, the positive electrode of the diode 55 is electrically connected with the end of the eighth resistor 544 close to GND, and the negative electrode of the diode 55 is electrically connected with the end of the eighth resistor 544 close to VCC;

[0066] One end of the fifth capacitor 535 is electrically connected with the eleventh pin of the double time base integrated chip 51, and the other end is connected with GND.

Since the fourth capacitor 534 cannot be charged in time, the eighth pin and the twelfth pin of the double time base integrated chip 51 are at high level, the ninth pin of the double time base integrated chip 51 outputs low level, the third triode 523 is turned on, and the high level output from the fifth pin of the double time base integrated chip 51 caused by the first capacitor 531 which also cannot be charged in time is forcibly pulled down, thereby preventing the misoperation of the relay. With the continuous charging of the fourth capacitor 534, the eighth pin and the twelfth pin of the double time base integrated chip 51 are lowered, and when the eighth pin of the double time base integrated chip 51 is lower than 1 / 3 Vcc, the circuit state is reversed, the ninth pin of the double time base integrated chip 51 changes from "0" to "1", Q2 is cut off, and the power-on reset is completed. In the circuit, the start-up delay time tw=1.1×R eighth resistor 544 resistance×fourth capacitor 534 capacitance, and the diode 55 is used for discharging the fourth capacitor 534 after power-off, so as to prepare for the next power-on reset.

[0069] The mobile signal shaping module 7 and the voltage stabilizing circuit 8 are further included.

[0071] The locomotive I end unlocking button 711 is electrically connected with the locomotive mobile signal shaping circuit 74 through an I end unlocking signal shaping circuit 712.

[0072] The locomotive II end unlocking button 721 is electrically connected with the locomotive mobile signal shaping circuit 74 through an II end unlocking signal shaping circuit 722.

[0073] The locomotive reversing handle 73 is electrically connected with the locomotive mobile signal shaping circuit 74.

The circuit diagram of the voltage stabilizing circuit 8 is shown in Figure 4 .

[0076] The old anti-collision earth controller is powered by DC 110V through resistance step-down, due to the voltage difference from 110V to 12V is too large, the resistance generates a lot of heat, and a large amount of energy is consumed on the resistance. When the circuit drives 12V relay to act, the voltage is insufficient (10.4V in actual measurement), which causes the contact pressure to be insufficient, and the signal sent to the operation monitor is too weak, which is one of the reasons why the locomotive monitor 4 does not start control.

[0077] The embodiment adopts DC / DC power conversion technology to improve the use efficiency of electric energy, and through the DC / DC conversion module to ensure that the 12V relay has sufficient action time voltage, to enhance the signal sent to the locomotive monitor 4, and to ensure that the operation monitor can be reliably started. Moreover, the scheme is also suitable for power supply of different types of locomotives.
