Abstract
The utility model discloses a locomotive microprocessor control system integrated with an alarm function. The locomotive microprocessor control system comprises a locomotive microprocessor and a driver controller, a speed sensor, a response pedal, an alarm response box, a locomotive display screen, an exciter and a brake system that are connected with the locomotive microprocessor. The locomotive microprocessor control system is characterized in that the locomotive microprocessor is connected with the driver controller through a rigid wire, the speed sensor is arranged on a locomotive wheel set, and a pulse signal is transmitted to the locomotive microprocessor through a rigid wire; the response pedal and the alarm response box are connected with the locomotive microprocessor through a rigid wire; the locomotive microprocessor is connected with the exciter through a main contact of an excitation contactor; the locomotive microprocessor is conducted with a parking electromagnetic valve inside the brake system through a contact of a parking relay; and the locomotive microprocessor is in communication connection with the locomotive display screen. The locomotive microprocessor control system has the advantages that as no alarm devices are additionally arranged, the hardware cost is lowered, the extra wiring procedures and mounting spaces are reduced, and the difficulty in overhaul and maintenance of the system is also reduced.
Description
Technical field
The utility model relates to a kind of Locomotive Microcomputer Control System of integrated vigilant function.
Background technology
When locomotive is driven a vehicle for preventing the behaviors such as dozing off, leave the post appears in the trainman; Or when sick and wounded, forfeiture car controlling ability occured promptly the driver, locomotive can initiatively unload, stop, and therefore, usually need to increase vigilant function at locomotive.Existing locomotive all adopts and installs the vigilance device with vigilant function additional and realize.Existing vigilance device has mainframe box, report to the police reply box, reply pedal, the hardware devices such as speed sensor, pressure sensor, stop mechanism, by realizing vigilant function in original locomotive electric cad system system and brake system through complicated transformation.This kind mode has not only increased the hardware cost of locomotive, but also needs to increase extra wiring and installing space, is unfavorable for repair and maintenance.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of Locomotive Microcomputer Control System of integrated vigilant function is provided.
The technical solution of the utility model is: a kind of Locomotive Microcomputer Control System of integrated vigilant function comprises locomotive microcomputer and the controller that links to each other with locomotive microcomputer respectively, speed sensor, replys pedal, reports to the police and reply box, exciting dynamo and brake system; Described locomotive microcomputer is connected rigid line to connect with controller; Described speed sensor is installed on the train wheel, sends impulse singla to locomotive microcomputer by rigid line; The described pedal of replying is replied box with warning and is linked to each other with locomotive microcomputer by rigid line; Described locomotive microcomputer is connected with exciting dynamo by the main contact of excitation contactor; Described locomotive microcomputer is by the electromagnetic valve for braking of the contacting brake system inside of shut down relay.
Described locomotive microcomputer also is connected with the communication of locomotive read-out.
Described locomotive microcomputer adopts the RS485 mode to be connected with the communication of locomotive read-out.
Compared with prior art, the utility model has the advantages that:
1, locomotive microcomputer itself has been integrated the various switching values of whole locomotive and analog quantity information, to watch out for function and be integrated into microcomputer system inside, be more conducive to locomotive microcomputer according to actual conditions, judge driver's exercises, response driver's associated responses, the driver is pointed out and reports to the police, and can the vigilant alert event of real time recording.
2, the phase difference according to speed sensor output is two groups of independence spike trains of 90 degree, and the opposite characteristic of lead lag relationship of two-way pulse when traction electric machine rotates and reverse, and locomotive microcomputer is to locomotive operation direction automatic decision.
3, after the vigilant function that locomotive microcomputer is integrated, do not need newly-increased vigilance device, saved hardware cost, reduced extra cloth line procedures and installing space, alleviated the difficulty that system overhaul is safeguarded.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is system architecture schematic diagram of the present utility model.
The specific embodiment
A kind of Locomotive Microcomputer Control System of integrated vigilant function, as shown in Figure 1, comprise: locomotive microcomputer and the controller that links to each other with locomotive microcomputer respectively, speed sensor, reply pedal, report to the police and reply box, locomotive read-out, exciting dynamo and brake system etc., wherein:
Locomotive microcomputer is connected rigid line to connect with controller, controller sends gear signal to locomotive microcomputer by representing 4 binary encoding forms of 0～15 grade.
Locomotive speed sensor is installed on the train wheel, is used for gathering the train wheel rotating speed, and speed sensor sends impulse singla to locomotive microcomputer by rigid line, and locomotive microcomputer calculates the real-time speed of locomotive by impulse singla.
Reply pedal and warning and reply the function that box all has reception driver acknowledge signal, in the locomotive operation process, in the every 60s of driver, step on and reply pedal, or the answer button of replying on the box that pushes for emergency all can produce acknowledge signal, locomotive microcomputer collects this switching value acknowledge signal by rigid line, judge that then the driver replys, operation is normal, not output alarm.If nonreply in the 60s, locomotive microcomputer with output signal, are replied box by rigid line control warning and are reported to the police.
Locomotive microcomputer is by the control excitation contactor, and the main contact of excitation contactor is connected with exciting dynamo.When locomotive microcomputer control excitation contactor was connected, the main contact of excitation contactor was closed, so that exciting dynamo gets is electric.Locomotive begins to load.
Locomotive microcomputer control shut down relay, the electromagnetic valve for braking of shut down relay contacting brake system inside, thus produce brake action.Make the locomotive unloading, and out of service.
Locomotive microcomputer and locomotive read-out adopt the communication of RS485 mode, and locomotive microcomputer transmits vigilant response message and shows in real time to the locomotive read-out.
Claims (3)
1. the Locomotive Microcomputer Control System of an integrated vigilant function, comprise locomotive microcomputer and the controller that links to each other with locomotive microcomputer respectively, speed sensor, reply pedal, report to the police and reply box, exciting dynamo and brake system, it is characterized in that: described locomotive microcomputer is connected the rigid line connection with controller; Described speed sensor is installed on the train wheel, sends impulse singla to locomotive microcomputer by rigid line; The described pedal of replying is replied box with warning and is linked to each other with locomotive microcomputer by rigid line; Described locomotive microcomputer is connected with exciting dynamo by the main contact of excitation contactor; Described locomotive microcomputer is by the electromagnetic valve for braking of the contacting brake system inside of shut down relay.
