Description

Marine telegraph

Technical field

The utility model relates to ship electronic technical field, particularly relates to a kind of carriage clock that can control ship power.

Background technology

Marine telegraph as main body instrument, is the necessary equipment carrying out power control in ship's navigation process in marine navigator.Carriage clock function is sent out by certain protocol signal by the power notch that user handles.The carriage clock inner structure more complicated of producing both at home and abroad at present, generally take secondary gear to carry out transmission, requirement on machining accuracy is higher, therefore expensive, and safeguards inconvenient; In addition, interface not opening, if the various equipment that will be applied to domestic independent research, as Large-scale ships operation simulator etc., must follow the communication protocol of the other side, and the communication interface adopting the other side to provide, very inconvenience; Meanwhile, there is a lot of finished product carriage clock for car and complete car function without independent push-botton operation, do not meet the operating habit of real ship bridge.

Utility model content

The utility model overcomes above-mentioned technical deficiency, provides a kind of structure simple, easy to maintenance, and scalability enriches, and compact size, cheap, has standby car, complete car button separately, and can give the marine telegraph of alarm to invalid operation.

The technical scheme that the utility model adopts is:

The utility model is a kind of marine telegraph, comprises clock body, push rod, is arranged on the gear display disc on clock body, waver, separately standby car, complete car button, and is arranged on the control circuit board in clock body.Wherein, waver is fixed on clock body, and its axle is connected with push rod, also designing one piece of iron plate in clock body inside is fixed on waver behind, strengthen fastness and durability, promote the feel promoted, waver is connected with control circuit board by corresponding winding displacement.

Control circuit board comprises again single-chip microcomputer, gear value read module, key control module, brightness control module, level switch module and power module of voltage regulation.Need during use first by standby car button, carriage clock to be switched to standby car state, user's driving handle drives gear shifting device to rotate, gear shifting device one end is connected with AD sampling module by data line, AD sampling module reads gear value, and send gear value to single-chip microcomputer, effective gear value is sent to host computer by level shifting circuit after data are carried out filtering process by single-chip microcomputer.

Compared with prior art, the beneficial effects of the utility model are: not only structure is simple for it, drives waver to realize gear switch by operating rod, easy to maintenance, and abundant scalability is provided, different communication protocol can be set as required, and compact size, cheap, there is standby car, complete car button separately, and alarm can be given to invalid operation, be applicable to real ship or ship maneuvering simulator use, there are wide market outlook.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further illustrated from one-piece construction, inner structure and circuit.

As shown in Figure 1, this marine telegraph, comprises clock body 1, push rod 2, is arranged on the gear display disc 3 on clock body, waver 4, separately standby car, complete car button 5, and is arranged on the control circuit board 6 in clock body.

As shown in Figure 2, waver 2 is fixed on clock body 1, and push rod 1 is directly set on the axle of waver 2 by the corresponding perforate 5 of design, meanwhile, axle has dug aperture, directly axle and push rod has been fixed together by screw, reduces rocking when promoting; Meanwhile, for increasing damping, promoting the feel promoted, being fixed on the behind of waver 2 at the inner also design of clock body one piece of iron plate 3, and increasing a firm banking 4 between two waveres, strengthening fastness and durability, promote the feel of promotion greatly.

As shown in Figure 3, control circuit comprises single-chip microcomputer, AD sampling module, key control module, brightness control module, level switch module and power module of voltage regulation.

Single-chip microcomputer is connected with AD sampling module, key control module, brightness control module and level switch module by signal wire, and power module of voltage regulation is connected with single-chip microcomputer by electric power conductor, for single-chip microcomputer provides electric energy; Level switch module is mainly used in data message and exports, and has 485 or 232 communication interfaces available; On single-chip microcomputer RXD, TXD pin be connected with level switch module by signal wire, ADC0, ADC1 pin is connected with AD sampling module, and CCR0 pin is connected with brightness control module.

Namely the crucial problem of the utility model marine telegraph one of will solve is read gear value problem.Here the resistance in main continuous welding 9 10K Europe in waver, and add outside the voltage of+5V at resistance two ends, magnitude of voltage corresponding to current gear is read by AD sampling module, by 9 resistance, 0 ~ 5v average voltage is divided into 10 parts, every part of 0.5V, then just can determine current gear value by corresponding magnitude of voltage, thus realize the function reading gear value.

The using method of this device: faced up by marine telegraph and be arranged on Large-scale ships operation simulator or real ship, data line Access Control platform, can use after connecting 12V direct supply.

Claims (2)
