Description

A beacon light information release system

technical field

The invention relates to a system for distributing information of navigation lights, which is used for distributing hydrological information to passing ships.

Background technique

Navigation light is a kind of traffic light installed on some navigation marks to ensure the safe navigation of ships at night. The fundamental purpose of the beacon light is to transmit hydrological information to passing ships. At present, there are two ways for the beacon light to transmit information. One is to emit light at night. This method will not cause signal interference, but the amount of information transmitted is less , can only send the geographic information of the navigation route to the surroundings, and cannot provide a large amount of hydrological information required by the ship; the other is to release the collected hydrological information to the surroundings using radio frequency signals. This method transmits a large amount of information, but For places that cannot be covered by wireless signals, it is difficult for ships to obtain relevant information, and the signals are easily interfered during transmission.

The light-emitting element has a certain flash frequency, that is, the light-emitting element has a light-emitting time zone and a non-light-emitting time zone. The modulation module is used to modulate the hydrological signal to the light-emitting time zone of the light-emitting element. After the hydrological signal is modulated The time series signal is converted into a time series signal, and the power amplifier module is used to amplify the time series signal.

The beneficial effects of the present invention are:

1) The hydrological information collected by the sensor is processed by the encoding module and the modulation module and then converted into a time series signal. After the time series signal is amplified by the power amplifier module, the light-emitting element is controlled to flash in a certain time sequence to transmit the hydrological information. Large capacity, strong anti-interference.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

An information release system for navigation lights, including sensors, encoding modules, modulation modules, power amplifier modules and light-emitting elements, the signal flow of the system is shown in Figure 1, the sensors are used to collect the required hydrological information (such as water depth, flow velocity, water temperature , wind speed, geographic coordinates, etc.), the encoding module is used to encode the collected hydrological information, and the hydrological information (digital signal) is encoded according to certain rules (such as Moore telegraph encoding and other encoding rules) and converted into hydrological signals (pulse signals), The light-emitting element has a certain flash frequency, that is, the light-emitting element has a light-emitting time zone and a non-light-emitting time zone, and the modulation module is used to modulate the hydrological signal to the light-emitting time zone of the light-emitting element, and the hydrological signal is converted into a timing signal (timing pulse signal) after modulation. ), the power amplifier module is used to amplify (amplify) the timing signal, and the timing signal after the power amplification controls the light-emitting element to flash in a certain timing to transmit the high-frequency optical signal containing hydrological information (the light-emitting time zone is the information transmission time zone).

The hydrological information collected by the sensor is processed by the encoding module and the modulating module and then converted into a time series signal. After the time series signal is amplified by the power amplifier module, the light-emitting element is controlled to flash in a certain time sequence so as to transmit the hydrological information to the surrounding ships (the surrounding ships obtain all information after decoding according to the message protocol. need hydrological information), the present invention transmits hydrological information through the flickering of light, with large amount of information and strong anti-interference.

In the present invention, the light-emitting element is a light-emitting diode. In order to be different from the general-purpose lighting lamp, the beacon light is not always on but flashing, and the flash frequency of the light-emitting diode is more than 20 times per minute and 70 times Below; the frequency of the hydrological signal is more than ten times the flash frequency of the light emitting diode; the effective light intensity of the light emitting diode is above 1600cd (the flash effect is brighter). In the present invention, the light-emitting diodes have multiple colors, and the light-emitting diodes of different colors release different hydrological information (more hydrological information can be transmitted within a limited time, and the efficiency of information transmission is improved).

As shown in Figure 2, it is the signal processing flow of the present invention. The hydrological information collected by the sensor is a digital signal, which is converted into a hydrological signal (pulse formation) after being processed by the encoding module (binary compilation), as shown in Figure 3, and finally modulated Under the processing of the module, the hydrological signal and the light-emitting diode flashing signal (controlling the light-emitting diode to flash at a certain frequency) are converted into timing signals by AND operation, and finally amplified by the power amplifier module.

When one luminous time zone cannot publish all the hydrological information (that is, the information transmission time zone is smaller than the hydrological signal time zone), the content of the hydrological information can be divided into two or more time zones for publication, and the contents of each time zone use connectors (such as "AND" )Link. Then in order, the send packet and the light-emitting diode flashing signal are ANDed to generate a corresponding timing signal, and finally all the information in the time zone of the hydrological signal can be sent out.
