Technical background of draft

As the standard of living improves and the leisure culture spreads, the population that enjoys rest and camping out of the city on a holiday or mountain or valley is rapidly increasing. In addition, according to this trend, the residential population managing the large and small amusement facilities dealing with the visitors coming to the place where the beautiful scenery of the valley is beautiful is increasing rapidly.

On the other hand, the weather in the mountainous regions is very variable, and it is very difficult to predict and alarm the weather by the usual weather observation method. This is because the mountain climate has the following characteristics.

First, it is unpredictable as a guerrilla heavy rain falling in mountainous areas in summer.

Second, guerrilla heavy rain falls locally, and in a short time, it is concentrated, so the amount of rainfall per unit area and unit time is very large.

Third, the valley of the mountainous area has a deep slope, so the flow velocity is very fast and the impact is large.

Fourth, because the valley of the mountainous area is short, unlike the general river, the upstream rainfall changes rapidly affect the downstream.

Due to the nature of the mountainous weather, flash floods in mountainous areas rapidly increase the amount of water in the valley in a short time, and the rapid mooring affects the downstream in a short time. Generates.

For this reason, the automatic rainwater warning system installed in the mountainous area breaks down the observation time and continuously observes the change of rainfall in the upstream area by the granular time unit, so that when a large amount of rain falls from the upstream of the valley, sudden flooding occurs. It must be designed to be detectable and, accordingly, promptly issue an emergency alert to induce a safe escape for holidaymakers and residents in downstream areas.

In addition, in order to issue an emergency alert, the situation on the site is very urgent, so the current weather situation and the site situation should be informed in detail considering that the residents do not have time to figure out the situation and find ways to deal with it. In addition, evacuation tips and evacuation sites should be more accurate and specific in order to ensure the safety of vacationers and residents.

To this end, the applicant has devised a patent for the automatic rain alarm system and alarm method for observing an unexpected flood in a mountain area and alarming it, and registered it (Registration No. 10-271534). The device has been installed in many mountainous areas and has contributed greatly to ensuring the safety of residents and tourists. The system has reached the present time with many improvements in the operation of the system after installation.

Conventional Technology

The automatic rainfall measuring system and its alarm method currently installed and operated in a mountainous area will be described with reference to FIG. 1 as follows.

The structure of the conventional automatic rain alarm system is large,

A superior station (100) installed at the upstream element of the valley and performing a function of observing the amount of rainfall generated upstream of the valley;

It is installed in a valley where water can be played, such as campsites, and the contents of alarms and evacuation orders are recorded in ADPCM method and stored in memory. An alarm station 200 for outputting a pre-recorded content according to a command;

Normally, observation information and equipment status information of superior station and control station are collected at regular time intervals, and when rain event is received from the superior station, it is determined whether or not an alarm will be issued and which type of alarm will be issued. After that, if it is determined that the alarm is required to issue a control station 300 for transmitting an alarm command to the alarm station;

A monitoring station 400 that collects and monitors all situations occurring at a remote control station or manually instructs alarms and announcements, while also generating processed data such as reports using the collected data; Consists of.

In addition, the superior station 100 receives power from the power supply device 150, and consists of a remote control unit (RTU) 111, a transceiver 112, an antenna 113 and an RF modem 114. It is provided with a data transmission device 110, consisting of a rain collecting device (120) consisting of a rain gauge (122) for measuring rainfall and a storage (Recorder) for storing data,

In addition, the alarm station 200 is supplied with power from the power supply device 250, and consists of a remote control unit (RTU) 211, a transceiver 213, an antenna 214 and the RF modem 212 Data transmission device 210 is provided, and is composed of a broadcast device 220 consisting of an amplifier 222, a message generator 221, a microphone 224 and a speaker 223,

In addition, the data processing unit 320 constituting the control station 300 is composed of a PC (322) and a printer 321 for inputting and displaying data, the remote control unit 310 is a control unit (RTU) ( 311), the transceiver 313, the RF modem 312 and the antenna 314, the data processing unit 320 and the remote control unit 310 is a power supply from the power supply unit 350 for supplying AC110 / 220V It is configured to receive.

Referring to the operation of the conventional automatic rainfall alarm system configured as described above,

The superior station 100 is installed in a number of places that need to observe the rainfall upstream of the valley, the rainfall observation in the area is carried out every 1 minute and once observed data is stored in its own storage device every 10 minutes When the data request from the empire 300 transmits the stored data. In addition, the superior station 100 calculates the sum of rainfall during the preset observation time using the data observed in 1 minute unit, compares this value with the preset rainfall value, and then needs to issue an alarm by its own judgment. If it is determined that this information (this information is referred to as rainfall event) is also informed to the control station 300.

The alarm station 300 is usually installed in a valley, such as camping, can play in the water. The alarm station 200 records the contents of the broadcast to be alarmed in advance in the ADPCM method and is stored in the memory, and according to the broadcast command received from the control station 300 (usually the control station is recorded when the broadcast command is transmitted to the alarm station). It transmits along with the memory number.) The message (prerecorded content) is output from the memory and broadcasted. The alarm station 200 sets the observation time and the rainfall value in the rainwater station 100 due to the flooding of the valley according to the rainfall observed in the rainwater station 100 and the rainwater value in three steps (boundary, Evacuation, severe evacuation).

The control station 300 normally collects observation information and equipment state information of the superior station 100 and the control station 300 at regular time intervals and receives an alarm event when a rainfall event is received from the superior station 100. Will be judged. There are three levels of alarm in the alarm command, which are divided into alert alarm, evacuation alarm, and severe evacuation alarm, and when the rainfall event is transmitted from the superior station 100 and the rainfall event of the upper level compared with the information stored in the memory. Only to selectively send the corresponding alarm command to the alarm station (200).

The monitoring station 400 collects and monitors or analyzes all situations occurring at the control station 300 at a remote location to manually instruct or supervise or manage an alarm and announcement command and also use the collected data. It also generates processed data such as reports.

<Problems with Prior Art>

In the conventional automatic rain alarm system, continuous technological development has been promoted, but the technology development mainly measures rainfall in the superior countries more precisely, while the control stations more accurately predict the variation of rainfall based on the measurement information of the superior stations. (For example, the measurement of the rainfall at the first 30 minutes to 1 hour interval is measured by analyzing the cumulative rainfall amount of 10 minutes in 1 minute unit), and accordingly, the variation of rainfall or sudden flood Predictive technology has made significant progress.

However, in the conventional automatic rain alarm system, when an emergency occurs and an emergency alarm is to be issued, only the contents recorded in advance by the ADPCM method can be repeatedly broadcast to the alarm station 200 under the control station 300's instruction. As a result, it was not possible to broadcast alarms appropriate to changing weather conditions.

Therefore, in a real situation, residents or resorters are only informed of the order of evacuation and only the usual evacuation instructions and evacuation sites. I could not hear the broadcast.

This is because the conventional alarm system is configured to broadcast only the message suitable for the situation from about 20 alarm messages recorded and stored in the alarm station 200 in the ADPCM method.

However, the actual alarm broadcast needs to contain as much detail as possible such as weather conditions at the time, rainfall, emergency status of emergency, evacuation tips and evacuation sites. And since such weather information is not always the same, it is necessary to change the alert message immediately to the appropriate contents for the changing situation from time to time.

However, in the related art, it is difficult not only to change the situation information at any time as described above due to the configuration of the system, but also to store various situation information because the capacity of the message is limited.

As a way to solve this problem,

First, it is possible to consider the problem of changing the stored alarm message from time to time.

However, it is practically impossible to record and save new evacuation tips every time according to the extremely variable weather conditions.

To do this, the operator who manages the device must raise his / her own voice or voice actor to record the alarm message for the expected situation in advance and store it in the memory of alarm station equipment from time to time. Capacity is not a fundamental solution because of its limited storage capacity.

Second, when the operator who manages the device in accordance with the generated situation inputs information and evacuation instructions through the microphone directly through the microphone, the voice signal is put on the VHF network and transmitted to the alarm station for broadcasting. The method can be considered.

However, this method has a problem that the contents of the alarm cannot be properly delivered because the noise mixed in the transmission also amplifies the broadcast voice signal due to the characteristics of the speaker device that broadcasts the alarm through the loudspeaker. In addition, in order to solve this problem, if the radio wave state between the control station 300 and the alarm station 200 is not smooth, it may be provided with a relay station to supplement the transmission of information. However, in this case, two frequencies should be used, which is a problem that it is practically impossible to obtain a radio wave use permit under the very difficult current radio management regulations.

Third, a case of converting a voice signal into a digital signal and transmitting the same may also be considered.

However, when the voice signal is converted into a digital signal, the size of the data is very large, which makes it difficult to apply it in a low speed communication network such as a VHF.

For example, assuming that 1 second of voice is sampled at 16 KHz, the PCM method has a capacity of 16 Kbytes, and when compressed with the ADPCM method, the capacity is about 4 Kbytes. When transmitting this to a narrowband VHF network, the transmission speed is about 1,200bps, that is, 150bytes / second. Therefore, it takes almost 27 seconds to 107 seconds to transmit 1 second of voice. do. Therefore, this cannot improve the urgency (rapidity) which is the life of the alarm device.

The present application was devised to solve the above problems,

The present application, in transmitting an emergency alarm message from the control station 300 to the alarm station 200, converts the contents of the alarm broadcast into text characters by using text / voice conversion technology (TTS), and then converts the contents of the alarm broadcast into text characters. When an emergency situation occurs, the operator of the control station inputs the situation and evacuation instructions of the site through the operator's input device of the data processing unit as text. The purpose of the present invention is to convert the received text information into a voice signal using the TTS module and output it, so that specific alarm information suitable for the situation of the site can be promptly issued.

In addition, by using the above text information as a medium for transmitting an alarm, the amount of data is minimized, thereby increasing the transmission speed recursively, and greatly improving the quality of alarm broadcasting by minimizing the noise introduced during the communication process. Another purpose.

Currently, TTS text transmission technology using a mobile phone is popular. The present proposal is to introduce the TTS type text transmission technology into the automatic rain alarm system. As described above, if the maximum data rate is set to 1,200bps in the VHF network, this means that two-byte Korean characters can be transmitted by 75 characters per second. This theory is already universal. Therefore, the technical gist of the present application is not in the new formulation of such a theory itself, but in adopting and using it in the automatic rain alarm system.

Applicant has already developed an emergency disaster / disaster alarm message transmission system using TTS. This system adds a text message transmission function using TTS technology to emergency disaster / disaster broadcasting networks installed in each town and village, and enables communication of emergency disasters / disasters through low-orbit satellites without interruption of communication under any circumstances. It is a device to make it. However, this system is different from the automatic rain alarm system to prepare for sudden flooding in the mountainous area in terms of communication system, so this principle is introduced into the automatic rain alarm system without specific design changes to the new system. You can't.

Therefore, the technical feature of the present application is to change the hardware / software configuration of the existing automatic rain warning system to enable the TTS type of text transmission.

The components of the present application are largely composed of the superior station 100, the alarm station 200, the control station 300, the monitoring station 400 is the same as the conventional technology. This is because the four components are the basic configuration of the automatic rain alarm.

Therefore, the specific technology of the automatic rain alarm device is greatly changed in its function by each detailed component, the superior station 100, the alarm station 200, the control station 300, the monitoring station 400, superior The configuration of the station 100 and the monitoring station 400 is almost similar to the prior art of the present application. However, the configuration of the alarm station 200 and the control station 300 is different from the prior art.

That is, the characteristics of the hardware / software configuration of the present application is in the detailed configuration and operating method of the alarm station 200 and the control station 300.

Referring to the operation of the present application configured as described above are as follows.

First, the rainfall sensor 140 of the superior station 100 installed in the elemental element upstream of the valley observes rainfall in the corresponding area every 1 minute, and then transmits the observed result to the RTU 130. The RTU 130 calculates the accumulated rainfall amount for 10 minutes every minute by using the received observation result and stores the accumulated rainfall amount in its own recorder 150 while analyzing the variation of rainfall. Meanwhile, the RTU 130 controls the observation result of the superior station 100 through the RF modem 120, the transceiver 110, and the antenna 160 in units of 1 hour at the request of the control station 300. To send. In addition, the RTU 130 of the superior station 100 analyzes the change trend by integrating the rainfall for 10 minutes measured in the above minute unit, and then the cumulative rainfall per unit time exceeds the value previously input to the recorder 150. If so, the result (event rainfall) is immediately transmitted to the control station 300 via the RF modem 120 and the transceiver 110.

Meanwhile, the RTU 330 of the control station 300 periodically requests the rainfall measurement result to the superior station 100 through the RF modem 320, the transceiver 310, and the antenna 360, and receives the received rainfall measurement result. Transfer to the data processing unit 300b. In addition, while monitoring the information transmitted from the superior station 100, when a sudden rainfall change occurs in the upstream region and the event rainfall is transmitted from the superior station 100, it is immediately transmitted to the data processing unit (300b).

The monitoring PC 390 of the data processing unit 300b, which receives the rainfall measurement value from the remote control unit 300a via the external communication device 384, analyzes the rainfall value by the monitoring software 392 mounted thereon. The analysis result is stored in the database 393, and determines whether an alarm is issued and the stage of the alarm (boundary, evacuation, serious evacuation). Subsequently, if it is determined that an alarm is required, the remote control unit 300a and the monitoring station 400 are notified.

The control station 300 collects observation information and equipment status information of the superior station 100 and the control station 300 at an interval of time, and immediately receives an alarm when a rain event is received from the superior station 100. You will be judged. There are three levels of alarm in the alarm command, which are divided into alert alarm, evacuation alarm, and critical evacuation alarm. The alarm stage is determined by comparing the rainfall event transmitted from the superior station 100 with the information stored in the memory. At this time, if a rain event of a lower stage is received, the alarm is omitted, and a duplicate alarm is prevented by selectively transmitting a corresponding alarm command to the alarm station 200 only in the case of a rain event of a higher stage.

On the other hand, the RTU 330 of the remote control unit 300a that has received the information for requesting the alarm from the data processing unit 300b is connected to the alarm station 200 through the RF modem 320, the transceiver 310, and the antenna 360. Notify the alarm command.

In addition, the control station personnel, if necessary, enters the new emergency alarm message information through the operator input device 385 of the control station 300 data processing unit 300b in text. This emergency alarm message is prepared to utilize all the situation information acquired by the operator to the maximum possible weather conditions and evacuation instructions. In this case, the text message input by the operator is output as text through the monitor 381 and the printer 383, and the voice information obtained by converting the text message into voice by the TTS engine 391 according to the operator's instruction is converted into a speaker ( 382) to allow the operator to confirm this directly. This is to prevent the error of syntax interpretation that can occur during parsing process and to ensure the accuracy of alarm contents by allowing the operator to check the contents to be alarmed. If the result of the check is satisfactory, the operator stores the data in the database 393 and simultaneously codes them by the monitoring software 392, and then outputs the result to the alarm station 200 through the remote control unit 300a. ).

In this case, the alarm command transmitted from the control station 300 to the alarm station 200 is transmitted through the VHF network via the antenna 360.

On the other hand, the RTU 230 of the alarm station 200 installed in an area in which tourists or residents are concentrated is the content of the alarm broadcast received from the control station 300 through the transceiver 210, the RF modem 22, and the antenna 260. It is stored in advance in the ADPCM unit 240 in the ADPCM method or stored in the TTS module 250 in the form of text information.

Subsequently, when it is determined that an alarm is required, if the memory number is received from the control station 300 together with the alarm broadcast command, the RTU 230 analyzes the contents of the command, and if the ADPCM broadcast command is received, the ADPCM unit 240. After the alarm message is stored and reproduced, the alarm message is output to the speaker 284 through the pre-amp 281, the power amp 282, and the speaker detector 283. At the same time, the alarm broadcast of the same content is output from the speaker 352 of the control station 300.

In addition, if the alarm broadcast command received from the control station 300 and the number of the memory number is a text information message, the RTU 230 analyzes the contents of the command, and then stores the transmitted message in the TTS unit 250 once and transmits the voice signal. After conversion to the output, the output via the pre-amp (281), power amp (282) and speaker detector (283) to the speaker 284. At the same time, the alarm broadcast of the same content is output from the speaker 352 of the control station 300.

Through this process, the alarm command issued by the control station 300 is transmitted to the alarm station 200 within a short time, and is a clean sound quality with almost no noise mixed, and the downstream state contains more detailed weather situation information and evacuation tips. Emergency warning messages will be given to local vacationers and residents.

However, the alarm station 200 or the control station 300 analyzes and predicts the situation of sudden flood based on the rainfall value observed by the superior station 100, and accordingly, triggers three warning stages (boundary, evacuation, and severe evacuation). The process of analyzing and determining where is applicable is the same as in the related art.

3 to 5 are signal flow diagrams illustrating in detail the signal processing of the alarm station 200 and the control station 300 described above.

1) First, the signal flow of the control station will be described in more detail with reference to FIGS. 4A and 4B.

First, the control station 300 initializes environment variables and communication ports of the remote control unit 300a and waits for reception of information.

Subsequently, when the Dow information is received from the superior station 100 through the antenna 360, the transceiver 310, and the RF module 320, the controller 330 first receives the latest Dow information and then determines whether a predetermined time has elapsed. Check it.

If the specified time has elapsed, go to the step of checking whether it is the regular data collection time, and if the specified time has not elapsed, check whether the received Dow information is higher than the recently received Dow information.

Subsequently, if the received Dow information is not the Dow information for the upper level, the process moves to the step of checking whether the regular data collection time is determined. If the Dow information for the upper level, the step of the alert corresponding to the received Dow information is determined.

Then, check whether the regular data collection time has arrived, and if the regular data collection time is not reached, go to the step of checking the manual guide broadcast request.If the regular data collection time is reached, call each excellent station and alarm station regularly to collect the data. Collect.

Subsequently, after checking whether or not manual announcement is requested, if a manual announcement is not requested, the predetermined alarm issuance command is transmitted to the alarm station, the Dow information is received, and if the announcement is requested, the ADPCM Check whether the command is a broadcast command or a TTS broadcast command.

Subsequently, if the requested command is an ADPCM broadcast command, the ADPCM broadcast command is transmitted to the alarm station. If the command is a TTS broadcast command, the TTS broadcast command is transmitted to the alarm station, and then the control proceeds to receiving Dow information.

Here, the selection of the broadcast command from the ADPCM broadcast command and the TTS broadcast command is a decision of the operator of the control station, and the operator of the control station determines and transmits it through the operator input device 385.

In addition, if the operator wants to select a command for TTS broadcasting, the operator should immediately input text information to be broadcasted through the operator input device 385 according to the process of FIG. By editing the information in the most appropriate form in consideration of the sudden flood situation and then transmitting it, the necessary information can be quickly and accurately delivered to the tourists or residents.

In addition, when the broadcast command is transmitted to the alarm station, the broadcast can be delivered to all alarm stations, and the broadcast can be selectively transmitted to individual alarm stations, and the command is transmitted to the alarm station by discriminating according to an external input according to a user's request. .

In addition, the broadcast command requested by the user can be received using various types of communication methods such as CDMA (SMS), wired communication, and wireless communication.

2) The flow of the next alarm station will be described with reference to FIG.

When the alarm command is received from the control station through the above process, the signal is received by the RTU 230 via the antenna 260, the transceiver 210, and the RF modem 220 of the alarm station.

At this time, the RTU 230 of the alarm station checks whether a broadcast command from the control station is received while initializing the environment variable and the communication port of the alarm station.

Subsequently, when a broadcast command is received from the control station, it is checked whether there is a manual announcement request.

If the command from the control station is not a request for manual announcement, a sound source is generated according to a predetermined procedure to perform an alarm broadcast, and the result is transmitted to the remote control.If the command from the manual control station is a request for manual announcement, the requested command It is checked whether it is an ADPCM broadcast command or a TTS broadcast command.

Subsequently, if the requested command is an ADPCM broadcast command, a sound source is generated through the ADPCM module 240 and output to the pre-amp 281. If the requested command is a TTS broadcast command, the data received through the TTS module 250 is written. After converting by voice conversion, the converted voice signal is output to the pre-amp 281. The signal output from the pre-amp 281 is output through the power amplifier 282, the speaker detector 283, and the speaker 284 to the broadcast broadcast.

Subsequently, when the broadcast ends, the RTU 230 transmits the result data to the remote controller.

Here, if the command received from the control station is an ADPCM broadcast command, the content of the received command will be the broadcast number of the message. If the received command is a TTS broadcast command, the content of the command will be the character information to be broadcast.

The remote control unit then checks whether there is a separate data request (this is a regular data request).

If there is no separate request for data, the check goes to the step of checking whether or not to receive the broadcast command. If there is a separate request for data, the remote control unit transmits the requested data and then moves to the step of checking whether to receive the broadcast command.

3) Next, the process of inputting the character information in the data processing unit will be described with reference to FIG.

If the operator of the control station decides that it is inappropriate to automatically send an alarm message, and wants to input the text alarm message manually, the operator operates the operator input device 385 to select the input of the emergency text alarm message, and the emergency text alarm message. Enter your message.

Then, when the input is complete, check the contents of the input and select whether to modify it. This means correction on the screen.

If the modification is selected, go to the step of inputting the emergency text alarm message again, and if not, confirm the output of the input.

If you do not need the output of the input (if it is confirmed enough on the screen), go directly to the step of transmission, and select the output if you want the output to confirm the input.

Then, when the means to output is selected, the result input through the means is output. This output means is the voice output through the speaker, the text output through the printer, the voice and the simultaneous output through the printer through which the operator listens or sees the content to broadcast in advance to prevent the occurrence of syntax errors during the parsing It is possible to prevent in advance and to review the adequacy of the entire broadcasting content in advance.

After checking whether or not to correct the modification, if you wish to modify, go to the step of entering the emergency text alert message, if you do not want to correct the transfer to the step of determining whether to send.

Then, if the transmission is not desired, the situation is terminated. If the transmission is desired, the text information is transmitted to the remote control unit via the external communication network, and this information is finally transmitted to the alarm station.

After the transmission is completed, the text information is saved in the DB and the input is terminated.

On the other hand, the monitoring station 400 collects and monitors or analyzes all the situation occurring in the control station 300 in the remote place to manually instruct the alarm and announcement command, and manages and supervises the management and also collected data You can also use it to generate processed data such as reports.

The function of the monitoring station is similar to that of the prior art.

Here, an embodiment of the communication protocol applied between the control station and the alarm station is shown in the following table.
