Description

Luminous label control system for controlling synchronous blinking status and confirming position by bidirectional communication method and onboard equipment used in such system

The present invention relates to a light emitting label control system capable of maintaining and managing a plurality of light emitting labels and controlling the flashing state synchronously. In particular, in an emergency, the asynchronous control of the flashing state is possible and the current position of each light emitting label. Label display system that can instantly detect the status of each component of the label and easily maintains and manages the best status by remote control. It relates to a payload device used in the system.

Ships that pass through ports for entry into ports or ships in low-depth specialty waterways generally must travel along narrow, meandering routes or waterways, and may be stranded at night. As the identification of the channel becomes more difficult, the risk increases. Moreover, nowadays, the urbanization of the port causes dazzling lights, such as neon signs, to obstruct the crew's sights, which hinders the identification of routes and waterways. Therefore, isolators are installed at regular intervals along such routes or waterways in order to facilitate the safe navigation of the ship by facilitating identification of such routes or waterways at night. Such lights are turned off during the day and then lit at night, and they are usually blinked periodically to increase their discretion, rather than staying lit at night. Such blinking state of the buoy is better to maintain the blinking synchronous blinking at the same time rather than each blinking in its own way.

The means that have been developed so far to control the flashing of such buoys are as follows.

First, there was a light sensing control device that provided a light sensor for each light buoy and automatically started blinking after sunset according to the illuminance detected by such light sensor. However, in the case of using such a photosensitive control device, not only the initial lighting time was different but also the control of the blinking time was not possible at all according to the sensitivity of the light sensor provided in each light buoy.

The first flashlight controller was developed to solve the problem of different timing of lighting, and is a synchronous flash control device named SCFM-1202, which is commercially available from CTK of Japan. It consists of a receiver unit and a clock unit with a PLL phase-locked loop, and receives the broadcast time signal of FM radio and uses it as a synchronization signal to synchronize the lighting time and the lighting time of the buoy. However, even in such a synchronous blink control device, only the lighting time and the lighting time are synchronized, and after the lighting, the lighting is blinking for a certain time, and the blinking time of each lighting is slightly changed, and eventually, the synchronization is distracted. .

In order to solve such a problem, the inventor of the present invention has developed a system for synchronizing a blinking synchronous flash by two-way radio data communication and filed it as a patent application No. 15153 dated September 13, 1991. Such an isochronous flashing system is installed in each isostat and functions as a station, and is controlled by communicating with the apparatus of the main station, which is a central processing station, using triple frequency. Such an isosynchronous synchronous flashing system enables not only to turn on and off all the lights at the same time, to maintain a synchronous flashing state during the lighting period, but also to determine the failure of each light bulb in the light bulb, and to provide a solar cell with each light. And can determine the failure of the battery and adjust the output voltage. However, such isosynchronous flashing systems are only lit, turned off and flashing in a manner that is synchronized by commands from the devices of the home country, so that the corresponding isomarks remain off when normal operation is impossible, such as causing the control center of the host to malfunction. Either lit or constantly lit.

In addition, the sea level on which the buoys are installed will always cause a storm, and such storms may cause the buoys to deviate from their original installation position. Such departures make it difficult or misleading for ships sailing by sea route or waterway, and, in the case of severe deviations, it may be impossible to retrieve them. Therefore, there is an urgent need for a means to easily identify the current position of each buoy in the home country and to send an immediate alert and take prompt action in the event of a departure from the home position. Could not be provided.

Therefore, according to the present invention, not only all the luminous labels can be turned on and off at the same time according to the instructions of the mother country, but also all the luminous labels can keep the synchronous flashing state after the light is turned on. If it is not possible to maintain the status, the corresponding flashing label flashes asynchronously, immediately identify the current position of each flashing label, and promptly and properly take action when the flashing label leaves the correct position. In the event that a lamp that is emitting light fails, it is to provide a light emitting label control system that can be quickly replaced with one of the spare lamps stored in the corresponding light emitting label by automatic control and remote control.

Referring now to FIG. 4, a description will be given of a method of managing and controlling a back mark using the light emitting label control system 100 according to the first and second embodiments of the present invention.

First, the process of controlling the operation of the register is described. As shown in the flowchart shown in FIG. 4, when the administrator of the central control station decides that the register should be flashed or when the preset time is reached, the mother station apparatus 110 receives the RF. Through the modem 162, the start signal of the register is sent to the mounting apparatus 150 of all the buoys (step 11), and the central processing unit 161 of the mounting apparatus 150 receiving the start signal receives the voltage checking means 192. Check whether the voltage is greater than the set voltage through (step 12), and if the check result is YES, turn on the power of the mounting apparatus 150 (step 13), and after the power is turned on (ON) Check the position of the book through the 180 (step 14), and check the state of the light emitting unit 170 through the status check means (173) (step 15), the positioning unit in the central processing unit 161 Processing information confirmed through the 180 and the status checking means 173 (step 16), and through the RF modem 162 Transmitting the processed information to the device 110 (step 17) and flashing the lamp of the lamp module 171 of the light emitting unit 170 through the synchronous flashing control means 164 according to the processed information (step 18). While the lamp is blinking, the mother station apparatus 110 periodically transmits a synchronization signal to the mounting apparatus 150 through the RF modem to maintain the synchronization state of the blinking time (step 19), and the central processing unit 161. Determines whether it is operating normally (step 20), and if the determination is YES, returns to step 14 to carry out the following steps to maintain the synchronous flashing control state, and if the determination result is NO, at step 21 The lamp asynchronously flashes by the asynchronous flash control means 165, and transmits an abnormal occurrence signal of the central processing unit 161 to the mother station apparatus 110 through the RF modem 162 (step 22). 110 restarts the central processing unit 161 with the mounting apparatus 150. (Step 23), the mounting apparatus 150 rechecks whether the voltage is equal to or higher than the set voltage (step 24), and if the check result is YES, determines whether the central processing unit 161 is operating normally (step 23). Step 25), if the judgment result is YES, terminate the asynchronous flashing state (step 26) and return to step 14 to return to the synchronous flashing control state while performing the following steps, and if the judgment result is no, return to step 21 and continue Maintain asynchronous flashing as you execute the steps. If the result of the check at step 12 and step 24 is no, at step 27, a signal indicating that the voltage is lower than the set voltage is transmitted to the mother station apparatus 110 through the RF modem 162, and at step 28, the power supply of the mounting apparatus 150 is applied. OFF. When the host station 110 receives the operation stop signal of the mounting apparatus 150 during any of the steps of the above control logic, the process immediately proceeds to step 28 to turn off the power of the mounting apparatus 150.

If either one is unable to maintain the synchronous flashing state, the corresponding register is flashed asynchronously, the current position of each register is immediately identified, and if the register is released from the correct position, prompt and appropriate action can be taken. If a lamp that is installed and emitting light fails, it can be quickly replaced with one of the spare lamps stored in the corresponding buoy by automatic control and remote control, so that the buoy can always be kept in the best state and operated.

According to the present invention, the synchronous flashing can be performed by using a central processing unit, and when the abnormality occurs in the central processing unit, the asynchronous flashing mode can be performed. In order to prevent failure due to the simple operation of the central processing unit, the mother station can send the reset signal to the central processing unit to restart the central processing unit, thereby improving the reliability of the system and making maintenance easier.
