Abstract

The utility model relates to an electrical fault dynamic testing and recording instrument for a diesel locomotive and comprises a shell body. The electrical fault dynamic testing and recording instrument for a diesel locomotive is characterized in that a monitoring circuit, a voltage reducing circuit, a holding circuit, an arithmetic circuit, a flip-flop circuit, an alarm circuit and a reserved circuit are arranged in the shell body. Because the utility model adopts the intelligent instrument to test the fault, the electrical fault dynamic testing and recording instrument for a diesel locomotive can precisely and efficiently find out the fault section. The utility model also uses the voice and a digital pipe to alarm a driver by using the voice processing technique and the digital display technique and prompts the emergency processing method. The driver is caused to be capable of testing and removing the fault point in the short time when the fault occurs suddenly. The electrical fault dynamic testing and recording instrument for a diesel locomotive saves the time and guarantees the unobstructed state of the entire circuit furthest.

Description

Diesel locomotive electrical accident detection of dynamic recording instrument

The utility model relates to a kind of diesel locomotive failure detector, specifically relates to a kind of diesel locomotive electrical accident detection of dynamic recording instrument.

Diesel locomotive is in the high-speed cruising process, and logic functions such as its startup, acceleration, permanent power traction, deceleration, rheostatic brake are to rely on tens electric link cooperation, finish jointly.If wherein any electric link breaks down, all can directly influence the realization of whole locomotive logic function, make the driver can't normal running, even cause interval the parking, can't continue operation.In the control circuit of present homemade series internal combustion locomotive, still the good intelligent check implement of neither one, in case driving electrical accident occurred in the way, only reliable driver's hand inspection, the failure judgement link, owing to do not allow interval mal to stop and plugged line on the transportation route, so the driver is under nervous irritable state, search position of fault and often need spend the plenty of time, even search less than position of fault and ask to rescue, cause the transportation fine not only for the driving unit, main is the obstruction that has caused the whole piece transportation route, makes the transportation-production of the overall situation sink into confusion, brings bigger economic loss.

The purpose of this utility model just is to provide a kind of diesel locomotive electrical accident detection of dynamic recording instrument that can detect the electrical accident position quickly and effectively.

The purpose of this utility model can realize by following measure:

The utility model comprises housing, in housing, be provided with supervisory circuit, reduction voltage circuit, lock-out circuit, arithmetical circuit, trigger circuit, warning circuit and reserved circuit, wherein supervisory circuit is connected with train signal line and breakdown signal line, and export reduction voltage circuit to, reduction voltage circuit is connected to lock-out circuit and warning circuit respectively, lock-out circuit exports arithmetical circuit to, arithmetical circuit exports trigger circuit to, trigger circuit export warning circuit to, and reserved circuit exports lock-out circuit, arithmetical circuit, trigger circuit and warning circuit respectively to.

Because the utility model adopts Artificial Intelligence Instrument that fault is detected, can find out failsafe link accurately, effectively, and utilize voice processing technology and digital technique of display to use voice and charactron to alarm driver, and prompting emergency processing method, make the driver when breaking down suddenly, can detect and get rid of the trouble point at short notice, save the time, also guaranteed the unobstructed of whole circuit to greatest extent.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1 is a schematic block circuit diagram of the present utility model.

Fig. 2 is schematic circuit diagram of the present utility model.

Fig. 3 is a shape assumption diagram of the present utility model.

The utility model is done explanation in further detail below in conjunction with drawings and Examples:

As shown in the figure: the utility model comprises housing, in housing, be provided with supervisory circuit, reduction voltage circuit, lock-out circuit, arithmetical circuit, trigger circuit, warning circuit and reserved circuit, wherein supervisory circuit is connected with train signal line and breakdown signal line, and export reduction voltage circuit to, reduction voltage circuit is connected to lock-out circuit and warning circuit respectively, lock-out circuit exports arithmetical circuit to, arithmetical circuit exports trigger circuit to, trigger circuit export warning circuit to, and reserved circuit exports lock-out circuit, arithmetical circuit, trigger circuit and warning circuit respectively to.Specifically: supervisory circuit is made up of 15 tunnel sampled signals and two-way subsidiary signal, and corresponding sampled signal becomes high level when locomotive breaks down.Reduction voltage circuit is made up of diode D1, stabilivolt DW1, auxiliary resistance, electric capacity and 4N35 photoelectricity isolated tube, is responsible for the sampled signal of 110V is depressurized to the 5V low-voltage signal and carries out the photoelectricity isolation.Reserved circuit is by 555 time base circuits, and counting machine 4017 is formed jointly, and being responsible for provides the cycle checkout signal to the logical operation circuit of detection record instrument, and whether the control detection recording instrument devotes oneself to work.Lock-out circuit is made up of 1413 darlington array pipes, and the alerting signal that its charge capture is less also makes it to amplify, and to guarantee energizing signal enough triggering power is arranged, and energizing signal is remained to reports to the police simultaneously finishes.Arithmetical circuit is made up of 4081 AND gate and 4011 NOT gate logic circuits, after sampling point captures breakdown signal, discern by above-mentioned decision circuit, whether really be failure condition, whether satisfy the fault alarm condition fully, only when satisfying the fault alarm condition fully, just trigger warning, otherwise, lock-out circuit is blocked, in case wrong report.Trigger circuit are made up of diode matrix circuit and switch AN, send into charactron actuator 4511 by diode matrix on the one hand through the energizing signal that excess current is amplified, make charactron demonstrate corresponding fault numbering, send into the voice integrated package by switch AN on the other hand, trigger out the audio alert content.Warning circuit rings producer 4017 by news, charactron LED and block of speech 5024 are formed, at first ring producer and send the caution sound equipment by news, charactron demonstrates the fault numbering simultaneously, certain fault has taken place in prompting driver locomotive circuit, if the driver does not know fault content and processing method, can be by the AN button, then voice 5024 send audio alert prompting processing method.

Principle of work of the present utility model is as follows: when fault occurs, be locked by lock-out circuit, and remain to and report to the police to finish, guaranteeing provides breakdown signal to arithmetical circuit all the time during reporting to the police, after arithmetical circuit receives breakdown signal, promptly in conjunction with the current potential situation of two-way from the subsidiary signal A and the B of driver controller handle position, carry out the logic analysis computing of fault, after being defined as true faucet, promptly report to the police by warning circuit, can voice or digital the demonstration report to the police.
