Abstract
The invention discloses a fault analog signal generator for a gear box. The fault analog signal generator for the gear box is formed by a first microprocessor and a signal generation circuit; the first microprocessor and a second microprocessor of a remote control system of a marine main engine are in communication through a bus; the signal generation circuit is used for generating operative fault signals of the gear box to be sent to the second microprocessor through the first microprocessor and a gear box system is broke down if the second microprocessor does not receive the operative fault signals of the gear box within the predetermined time; a display unit of the remote control system of the main engine provides corresponding alarm display when the gear box is broke down; accordingly effective self-inspection can be performed on the gear box system to confirm whether operative faults and communication faults exist or not under the condition that the main engine is not started when vessels stop at ports or are anchored on the sea.
Description
Technical field
The present invention relates to a kind of gearbox fault analog signal generator, is a kind of operation troubles signal that main frame just can be simulated the marine main engine gear case that do not start specifically, and the signal generator that its communication and operation troubles are detected.
Background technology
Marine engine remote control system realizes that as boats and ships an important component part of " unmanned engine room " more and more is subject to people's attention.Yet under many circumstances, a lot of marine incidents in reality or the perils of the sea are all to be caused by the out of control of main engine remote control system.
Whether main frame, as the power source of boats and ships, is related to boats and ships to its effective control and can normally navigates by water.And, as the controlled device of marine engine remote control system, whether can carry out accurately associative operation according to operator's operational order, most important for the security of boats and ships.
Gearbox system is an important component part of host computer system.The oil system of gear case, commutation are controlled, the de-row of closing controls and is related to positive car, parking, the reversing whether operator can normally realize boats and ships, and this is for the normal navigation of boats and ships, especially under some dangerous situations, can accurately control be particularly important.
For deficiency of the prior art, design a kind of gearbox fault analog signal generator, for stopping port or sea at boats and ships while casting anchor, in the situation that whether whether unactual startup host computer system exist operation troubles and exist communication failure to carry out self check with main engine remote control system gearbox system.This is conducive to solve in time before breaking down, for boats and ships escort.
Summary of the invention
Goal of the invention: the invention provides a kind of gearbox fault analog signal generator, in the situation that do not start main frame, simulation gear case operation troubles signal, in order to the communication that detects main engine remote control system and gearbox system, whether whether normal and gearbox system exists operation troubles.
Technical scheme: a kind of gearbox fault analog signal generator comprises first microprocessor and signal generating circuit;
Described first microprocessor is connected by the second microprocessor of bus and main engine remote control system, and the first microprocessor per second sends the communication test frame by bus to the second microprocessor, after the second microprocessor receives, returns to the communication acknowledgement frame.If reply normally, show that communication is normal, first microprocessor continues to send; If answer failed, send warning, show that communication breaks down.
The signal that described signal generating circuit produces comprises misorientation signal and gear case lubricating oil pressure low signal, is used for simulating the operation troubles signal of gear case.
Described signal generating circuit sends to first microprocessor by the gear case operation troubles signal of generation; First microprocessor sends to the second microprocessor by gear case operation troubles signal, if the second microprocessor is not received gear case operation troubles signal within the default time, shows that gearbox system breaks down.
Beneficial effect: compared with prior art, gearbox fault analog signal generator provided by the invention, stop port or sea while casting anchor at boats and ships, in the situation that unactual startup host computer system, only need to start main engine remote control system, just can whether exist operation troubles and communication failure to carry out effective self check to gearbox system.
The accompanying drawing explanation
The system architecture schematic diagram that Fig. 1 is the embodiment of the present invention.
Embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment only is not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, the gearbox fault analog signal generator, comprise the signal generating circuit for detection of the whether normal microprocessor 1 of the communication of gearbox system and main engine remote control system and generation misorientation signal and gear case lubricating oil pressure low signal.
Microprocessor 1 is the microprocessor 2 transmission communication test frames to main engine remote control system by the bus per second, and microprocessor 2 receives the communication test frame and sends the communication acknowledgement frame later.If reply normally, show that communication is normal, microprocessor 1 continues to send.If answer failed, send warning, show that communication breaks down.Microprocessor 2 answer faileds refer to and in one second, do not send the communication acknowledgement frame as microprocessor 2, and after communication is broken down, the display unit of microprocessor 2 instruction main engine remote control systems gives corresponding alarm indication.
Signal generating circuit produces and comprises misorientation signal and gear case lubricating oil pressure low signal, is used for simulating gear case operation troubles signal.
In the fault simulation situation, send the test command frame to microprocessor 1 by microprocessor 2 by bus, after microprocessor 1 is received signal, trigger pip produces circuit and produces fault simulation signal, this fault simulation signal is given the microprocessor 2 of main engine remote control system through microprocessor 1, in one second, do not receive corresponding fault-signal as microprocessor 2, show that operation troubles appears in gearbox system, the display unit of microprocessor 2 instruction main engine remote control systems gives corresponding alarm indication.
