Embodiment Construction

[0017] A locomotive microcomputer control system with integrated vigilance functions, such as figure 1 As shown, it includes: the locomotive microcomputer and the controller connected to the locomotive microcomputer, speed sensor, answering pedal, alarm answering box, locomotive display screen, exciter and braking system, etc., among which:

[0018] The locomotive microcomputer and the controller are hard-wired, and the controller transmits the gear position signal to the locomotive computer in the form of 4-bit binary code representing 0 to 15 gears.

[0019] The locomotive speed sensor is installed on the locomotive wheel set to collect the rotational speed of the locomotive wheel set. The speed sensor transmits the pulse signal to the locomotive microcomputer through the hard wire, and the locomotive microcomputer calculates the real-time speed of the locomotive through the pulse signal.

[0020] Both the response pedal and the alarm response box have the function of receiv...

Abstract

The invention discloses a control system integrated with a precaution function for a locomotive microcomputer control system and a control method. Various switching quantity and analog quantity information of a whole locomotive can be integrated by a locomotive microcomputer; the precaution function is integrated to the inner part of a microcomputer system to facilitate the locomotive microcomputer in judging various movements of a driver according to the actual conditions, responding relative responds of the driver, prompting and warning the driver, and recording a precaution alarming event in real time; the locomotive microcomputer can automatically judge the movement direction of the locomotive according to two groups of independent pulse arrays with a phase difference of 90 degrees, which are output according to a speed sensor, so as to carry out reverse current protection on the locomotive; and after the locomotive microcomputer is integrated with the precaution function, a precaution device does not need to be additionally arranged, so that the hardware cost is saved, the extra wiring procedure and mounting space are reduced, and the difficulty of overhauling and maintaining the system is reduced.

Description

technical field [0001] The invention relates to a locomotive microcomputer control system and a control method with integrated vigilance functions. Background technique [0002] In order to prevent the locomotive driver from dozing off or leaving work when the locomotive is running; or when the driver suffers an emergency injury or loses the ability to control the car, the locomotive can actively unload and stop. Therefore, it is usually necessary to add a vigilance function to the locomotive. Existing locomotive all adopts to install the vigilant device that has vigilant function to realize additionally. The existing vigilance device has hardware equipment such as a main box, an alarm response box, a response pedal, a speed sensor, a pressure sensor, and a brake mechanism. The vigilance function is realized through complex transformations on the original locomotive electrical system and braking system. This method not only increases the hardware cost of the locomotive, but...
