Abstract
An AIS pilot interface data transmission device with a pilot interface wiring testing function and a wiring error correcting function is capable of automatically testing whether interface wiring is correct or not, and indicating whether an interface wiring situation is normal or not through an LED indicator lamp, and has the wiring error correcting function by being provided with a circuit switching device for switching reversely connected wires.
Description
Affiliated technical field
The utility model relates to the data transmission device of a kind of AIS of connection pilot interface and computer or other data processing equipments.
Background technology
At present, known AIS pilot's interface data line is that simple the utilization has the data transmission device formation that cylindrical connector and RS232 serial ports commentaries on classics USB or RS232 serial ports change Bluetooth circuit; Its advantage is: simple to operate, reliable; Shortcoming is: in the wiring error or disconnection (this is recurrent thing at watercraft AIS) of AIS pilot's interface, the pilot can't judge it is that oneself computer is out of joint, or circuit question.Therefore this tends to bring poverty-stricken situation to the pilot.
Summary of the invention
In order to overcome the above-mentioned defective of existing AIS pilot's interface data line, the utility model provides a kind of AIS pilot's interface data transmission device of the pilot's of having interface distribution test function, whether this device test interface distribution automatically is correct, and indicate the interface circuit situation whether normal by a pilot lamp, exchange but also can will connect anti-distribution, correct function thereby have wrong line by a circuit switched device.
The technical scheme that its technical matters that solves the utility model adopts is: between the data input signal line and ground wire (the TX A of AIS pilot's interface and TX B line) of AIS pilot's interface data transmission device, light emitting diode of cross-over connection utilizes the characteristic of light emitting diode itself and the wiring correctness that duty detected and indicated AIS pilot's interface.And can adjust light emitting diode and make it be in suitable duty by being connected in series a resistance.This device has utilized the characteristic of light emitting diode cleverly, when having data-signal to pass through in the circuit, and the in running order lumination of light emitting diode that the change in voltage that causes makes, thus reflect the state of circuit.
Product can further be equipped with a circuit switched device, connects inverse time when detecting AIS pilot's interface distribution, can exchange by TX A and the TX B circuit of this circuit switched device with AIS pilot's interface, thereby solve the wiring error problem.
The beneficial effects of the utility model are: correct and when data output is arranged when the wiring of AIS pilot's interface, light emitting diode is glittering, when AIS pilot's interface circuit connects inverse time, light emitting diode Chang Liang, when wiring disconnects or does not have output signal, light emitting diode does not work, and the user can judge whether clearly that thus wiring is out of joint, and whether pilot's interface distribution is normal.And when finding wiring error, can the TX A and the TX B wiring of AIS pilot's interface be exchanged by being equipped with a circuit switched device, a method of dealing with problems is provided.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is one of the present utility model and implements illustration.
The 1.RS232 serial ports changes the USB/ Bluetooth circuit among the figure, 2. connects the TX A and the TX B circuit of AIS interface circuit end, 3.LED light emitting diode lamp, 4. circuit switched switch, 5. cylindrical connector, 6. shell.
Embodiment
In Fig. 1, comprise the RS232 serial port and changeed USB/ Bluetooth circuit (1) part, a LED light emitting diode (3) is connected across in the data input and ground wire (2) of RS232 serial port circuit end, select the TX A of AIS interface circuit and the connected mode of TX B circuit by a toggle switch (4), when switch pushes normal connection one end, TX A presses with TX B circuit and normally is connected, and when switch pushes the other end, TX A is connected with TX B circuit switched.
In embodiment illustrated in fig. 2, this device is connected with pilot's interface of AIS equipment by a special-purpose circular connector (5), the main circuit part all is encapsulated in the shell (6), indicate wire connection state by a LED light emitting diode (3), carry out line errors by a toggle switch (4) and correct.
Claims (2)
1. AIS pilot's interface data transmission device with interface distribution test function and distribution error correction, it is characterized in that: between the data input signal line and ground wire of this device, light emitting diode of cross-over connection, utilize the characteristic and the duty of light emitting diode itself, detect and indicate the wiring correctness of AIS pilot's interface.And can adjust light emitting diode and make it be in suitable duty by being connected in series a resistance.
2. AIS pilot's interface data transmission device according to claim 1 is characterized in that: by a circuit switched device distribution of AIS pilot's interface is changed.
