Description

  The present invention relates to a meteorological station, a meteorological information receiving station, a control method, and a program for processing meteorological information transmitted and received by wireless communication.

  Patent Document 1 discloses that when an automatic weather observation device or the like at a remote location is in an abnormal state such as a fall, the abnormal state is transmitted to the center by Internet e-mail (0009 in Patent Document 1).

A conventional weather station includes a wireless device and a weather observation device attached to the wireless device, and the wireless device wirelessly transmits weather information observed by the weather observation device in a packet format. At the Meteorological Bureau, the user selects a predetermined setting screen from the menu, and sets a transmission time interval from a plurality of transmission time intervals (eg, 5 minutes, 10 minutes, and 30 minutes) on the setting screen. The weather station transmits weather information packets at the transmission time interval.
JP 2001-16343 A

  The weather information packet should be sent frequently when the weather conditions are bad, etc., but in order to change the transmission time interval to a short one, the user needs to call the menu screen one by one and change the setting. There is.

  In addition, when weather conditions are good, weather information does not change frequently, so it is desirable to reduce the air traffic by setting a longer transmission time interval. To change the settings.

  Furthermore, the weather observation apparatus is usually installed outdoors with a radio, and the radio station of the meteorological bureau is also installed in the vicinity of the weather observation apparatus, so that a person can quickly reach the radio. However, in most cases, the user is away from the radio. Therefore, it becomes complicated to switch the transmission time interval of the weather information packet in accordance with the weather change.

  On the other hand, since the weather information receiving station receives weather information packets from many weather stations, even if the weather information is received from a weather station near the local station, it is difficult for the user to notice it. Even when the weather conditions are getting worse or stable, the conventional weather information receiving station always has the same received sound and reception screen, so the user will not be able to check the weather conditions unless they check the received weather data. I can't figure out.

  Patent Document 1 does not mention anything about control of a weather information transmission time interval and improvement of reception processing of weather information.

  An object of the present invention is to provide a meteorological station, a meteorological information receiving station, a control method, and a program with improved processing for meteorological information.

The meteorological information radio system 10 includes a plurality of meteorological stations A, B, and C and a meteorological information receiving station 15 as its own station, and the meteorological stations A, B, C and the meteorological information receiving station are equipped with radios. . Meteorological stations A, B, and C have fixed locations and are unattended. On the other hand, the weather information receiving station 15 is not only installed at a predetermined place such as a home or office, but may be carried by a user or mounted on a moving body such as a taxi.

  The meteorological information receiving station 15 receives meteorological information observed by the meteorological stations A, B and C in a meteorological information packet. The area, reference value, warning, and the like described in FIG. 1 will be described later.

  FIG. 2 is a detailed configuration diagram of the weather station 20. The weather station 20 collectively refers to the weather stations A, B, and C. The configuration of the weather information receiving station 15 is simply the weather observation device 25 removed from the configuration of the weather station 20. The meteorological station 20 is usually installed in a place where a person can quickly get there, away from the place of the person.

  The weather station 20 includes a panel unit 21, a radio unit 22, and a weather observation device 25. The panel unit 21 and the radio unit 22 constitute one radio device, and the weather observation device 25 is externally attached to the radio device so as to be separable. The meteorological observation device 25 observes a plurality of meteorological items such as rainfall, temperature, wind direction, wind speed, atmospheric pressure, and humidity using a predetermined sensor. The panel unit 21 and the weather observation device 25 include RS232C connectors 27 and 28, respectively, and observation data of the weather observation device 25 is sent to the panel unit 21 through the connection between the RS232C connector 27 and the RS232C connector 28.

  In addition to the RS232C connector 27, the panel unit 21 includes a display unit 30, an operation unit 31, a main microcomputer 32, a modem 33, a TNC (Terminal Node Controller) microcomputer 34, an EEPROM (Electronically Erasable and Programmable Read Only Memory) 35, and an RJ. -45 connector 36 is provided. The RS232C connector 27 can be connected to a GPS receiver instead of the weather observation device 25. The panel unit 21 is also equipped with a 2.5 mm stereo plug terminal.

  The display unit 30 includes an LCD (Liquid Crystal Display) and performs various displays based on data from the main microcomputer 32. The operation unit 31 includes operation keys, a click encoder, and an analog volume, and information on user operations on the operation unit 31 is sent to the main microcomputer 32. The main microcomputer 32 transmits / receives data to / from the TNC microcomputer 34 and the EEPROM 35 and performs predetermined processing.

  The modem 33 is interposed between the RJ-45 connector 36 and the TNC microcomputer 34 and transmits / receives data to / from the RJ-45 connector 36 at a communication speed of 1200 bps or 9600 bps. The main microcomputer 32 receives weather information from the weather observation device 25.

  The radio unit 22 includes a microcomputer main microcomputer 40, a transmission / reception unit 41, a built-in speaker 42, an antenna terminal 43, and RJ-45 connectors 44 and 45. The microcomputer main microcomputer 40 controls various elements in the radio unit 22. The transceiver 41 transmits and receives signals to and from the built-in speaker 42, the antenna terminal 43, and the RJ-45 connector 44. An antenna is connected to the antenna terminal 43, and a microphone (not shown) is connected to the RJ-45 connector 45.

  FIG. 3 is a setting screen for setting the transmission of the weather information packet in the weather station 20. The setting screen displays “WEATHER STATION” to indicate that it is a screen for setting transmission of a weather information packet. On the setting screen, the transmission (TX) setting is currently selected, and the setting value is OFF. The user can switch ON (transmit weather information packet) and OFF (do not transmit weather information packet) for transmission by operating a predetermined item value selection key of the operation unit 31. Further, the user operates the setting item selection key to switch from the transmission (TX) setting to the weather information packet transmission time interval (TX INTERVAL) setting. On the transmission time interval setting screen, the transmission time interval of the weather information packet is set to 10 minutes. The meteorological information packet transmission time interval is switched to three stages of 5 minutes, 10 minutes, and 30 minutes. This switching is also performed by operating the item value selection key of the operation unit 31.

  An outline of the processing of the weather station 20 will be described. More specific description will be given in the flowchart of FIG. In the weather station 20, weather information sent from the weather observation device 25 to the RS232C connector 27 of the panel unit 21 is sent to the TNC microcomputer 34. The TNC microcomputer 34 converts the weather information into a transmission format and passes it to the main microcomputer 32. The main microcomputer 32 performs predetermined processing on the meteorological information on the passed rainfall, temperature, wind direction, wind speed, pressure and humidity.

  FIG. 4 shows a reference value setting screen for each weather item included in the weather information. The setting screen of FIG. 4 is applied not only to the weather station 20 but also to the weather information receiving station 15.

  The reference value in the meteorological bureau 20 is when the transmission time interval of the meteorological information packet is set to the minimum value (10 minutes) of the above three steps when the observed value for each weather item is within a predetermined range. Means the upper limit or the lower limit of the predetermined range. Therefore, for each weather item, when the observed value is below the reference value (when the reference value is the upper limit) or above the reference value (when the reference value is the lower limit), the weather information packet transmission time interval is the minimum value Changed to (10 minutes). In the weather station 20, the predetermined range means a minimum transmission time interval setting range (or a maximum transmission frequency range).

  The reference value in the meteorological information receiving station 15 refers to the user of the meteorological information receiving station 15 when the observed value of each meteorological item received by the meteorological information receiving station 15 from the meteorological station 20 is within a predetermined range. When issuing a warning, it means the upper limit or the lower limit of the predetermined range. Therefore, for each weather item, when the received observation value is below the reference value (when the reference value is the upper limit. For example, in the temperature of FIG. 4, the reference value is −5 ° C. and the upper limit is −5 ° C. or less. In the range, when the reference value is −5 ° C. or less) or above the reference value (when the reference value is the lower limit. For example, in the air temperature of FIG. 4, 30 ° C. or more with the reference value 35 ° C. as the lower limit) When the reference value becomes 35 ° C. or more in the range of), a warning sound and highlighting of the corresponding data (described later with reference to FIG. 5) are performed when the observation place display screen is displayed at the weather information receiving station 15. The predetermined range means a warning range for the user at the weather information receiving station 15 for each weather item. In the weather information wireless system 10, the minimum transmission time interval setting range (or maximum transmission frequency range) in the weather station 20 and the warning range for the user in the weather information receiving station 15 are the same.

  The minimum transmission time interval setting range in the meteorological station 20 and the warning range in the meteorological information receiving station 15 are preferably set to be the same in the meteorological station 20 and the meteorological information receiving station 15, but the setting is the same. Since it is performed individually at the receiving station 15, different ones can be set for the meteorological station 20 and the meteorological information receiving station 15, or different ones can be set for each meteorological station 20. The reference value can be set in five types of rain, air temperature, wind speed, atmospheric pressure, and humidity, and is stored in the EEPROM 35.

  In FIG. 4, the minimum transmission time interval setting range in the meteorological station 20 and the warning range in the meteorological information receiving station 15 are 5 mm or more per hour for rainfall, −5 ° C. or less for air temperature, 35 ° C. or more, wind speed Is 20 m / h or more, the atmospheric pressure is 990 hPa or less, and the humidity is 10% or less and 80% or more. The minimum transmission time interval setting range in the meteorological station 20 and the warning range in the meteorological information receiving station 15 are set as value ranges when a bad change is expected for each weather item, that is, when a fast change is expected for the value of each weather item. . When the weather is good, the value of each weather item is stable and the change is expected to be sufficiently gradual.

  The “distance from own station” defined in FIG. 4 exists only in the warning range setting screen of the weather information receiving station 15, and is set to 10 km or less in FIG. That is, only the meteorological station 20 existing in a circular area having a radius of 10 km centering on the meteorological information receiving station 15 (corresponding to the area within the range in FIG. 1) becomes the warning target meteorological station. Specifically, in FIG. 2, weather stations B and C are warning target weather stations 20, and weather station A is a weather station that is not a warning target. Therefore, as shown in FIG. 1, for meteorological stations B and C, if the reference value is exceeded, a warning sound and a warning display are performed, and meteorological station A receives meteorological information out of range. Since it is transmitted to the station 15, the weather information from the weather station A does not shift to a warning sound or warning screen. The warning sound and warning display will be described later in detail.

  Returning to the description of the operation of the weather station 20, the weather information packet is transmitted from the main microcomputer 32 to the main microcomputer 40 of the radio unit 22 and transmitted as an electric wave from an antenna (not shown) connected to the antenna terminal 43. .

  An outline of the operation of the weather information receiving station 15 will be described. In the meteorological information receiving station 15, the transmission / reception unit 41 of the radio unit 22 sends the packet signal received by the antenna connected to the antenna terminal 43 to the panel unit 21. In the panel unit 21, the modem 33 receives the packet signal and decodes it. The decoded bit data string is processed by the TNC microcomputer 34 and the result is sent to the main microcomputer 32.

  Specific processing performed by the main microcomputer 32 of the weather information receiving station 15 on the bit data string will be described later with reference to the flowchart of FIG. An outline of the operation of the weather information receiving station 15 will be described.

  The weather information receiving station 15 determines whether or not the value of each weather item of the weather information received from the weather station 20 is included in the warning range of FIG. While displaying a weather warning sound from the built-in speaker 42, the display unit 30 displays a warning. The meteorological station 20 that has transmitted the meteorological information for operating the weather warning sound and the warning display function exists in a circular area centered on the own station and having a radius of the set value of the distance from the own station in FIG. It is limited to the weather station 20. In the example of FIG. 2, the weather station A is outside the warning area, and the weather stations B and C are within the warning area. Even if there is a weather item whose observed value is within the warning range, if it is from the weather station 20 in the predetermined area, the weather information receiving station 15 displays the weather warning sound and the warning screen. No action is taken.

  FIG. 5 shows a weather information confirmation screen displayed on the display unit 30 in the weather information receiving station 15. On the weather information confirmation screen, “MY WEATHER STATION” is displayed as a title, and items such as rainfall, temperature, wind direction, wind speed, air pressure, and humidity are displayed with icons and units below them. Then, for a value that is in the warning range, a display that emphasizes that the value is in the warning range, for example, blinking is performed. In FIG. 5, the temperature is within the warning range. On the conventional weather information confirmation screen, even if the temperature is in the warning range, it is continuously displayed as in the case of the rainfall outside the warning range.

  FIG. 6 is a flowchart of the weather information transmission routine 60. The weather information transmission routine 60 is executed in the main microcomputer 32 of the weather station 20. In S61, S62, S63, S64, and S65, the current rainfall, temperature, wind direction, wind speed, air pressure, and humidity observed by the weather observation device 25 are within a range corresponding to the shortest transmission time interval of the weather information packet. It is determined whether or not it is included. If all the determinations of S61, S62, S63, S64, and S65 are negative, the process proceeds to S66, and if at least one determination is positive, the process proceeds to S67. The range corresponding to the shortest transmission time interval of the weather information packet for the rainfall, temperature, wind direction, wind speed, pressure and humidity is the upper limit or lower limit of the reference value set by the user using the setting screen of FIG. The value range to be.

  In S66, the transmission time interval of the weather information packet is set to a value set by the user on the setting screen (FIG. 4) for the weather station 20, and the process proceeds to the next S68. In S67, the transmission time interval of the meteorological information packet is set to the shortest value (5 minutes out of the three steps of 5 minutes, 10 minutes and 30 minutes in the weather station 20), and the process proceeds to the next S68.

  In S68, it is determined whether or not the time has elapsed since the previous transmission time of the weather information packet. If the determination is positive, the process proceeds to S69. If not, the weather information transmission routine 60 is executed. finish. In S69, a weather information packet is transmitted. Thus, if at least one of the current rainfall, temperature, wind direction, wind speed, atmospheric pressure and humidity is included in the range set as the range corresponding to the shortest transmission time interval of the weather information packet for each weather item. The transmission time interval of the weather information packet is made the shortest, and the weather station 20 transmits the weather information packet at the shortest time interval.

  FIG. 7 is a flowchart of the weather information display routine 80. The weather information display routine 80 is executed in the main microcomputer 32 of the weather information receiving station 15. In S81, S82, S83, S84, and S85, it is determined whether or not the latest rainfall, temperature, wind direction, wind speed, pressure, and humidity received from the weather station 20 are included in the warning range. If all the determinations of S81, S82, S83, S84, and S85 are negative, the process proceeds to S86, and if at least one determination is positive, the process proceeds to S87. The warning range for the rainfall, temperature, wind direction, wind speed, atmospheric pressure and humidity is a value range in which the reference value set by the user using the setting screen of FIG.

  In S86, a beep sound is generated as a normal interrupt sound, and the values of the meteorological items such as rainfall, temperature, wind direction, wind speed, pressure and humidity received from the weather station 20 are interrupted and displayed on the display unit 30. In S87, a warning sound clearly different from the beep sound is generated, and the weather item in the warning range is blinked as shown in FIG. 5 to display each weather item value.

  Thus, the meteorological information receiving station 15 displays the weather data interrupt screen on the display unit 30 of the meteorological information receiving station 15 together with the reception of the meteorological information of the meteorological station 20, on which the rainfall, temperature, wind direction, wind speed, atmospheric pressure are displayed. For each value of humidity and humidity, if it is included in the range set in the weather information receiving station 15 as its warning range, the value is displayed blinking. When the interrupt screen starts to be displayed, a predetermined warning sound is output from the built-in speaker 42 for a certain period of time or for the entire period of display of the interrupt screen.

  FIG. 8 is a block diagram of the weather station 100. An example of the weather station 100 is the weather station 20 (FIG. 2). The weather station 100 includes a weather information acquisition unit 101, a transmission time interval setting unit 102, and a weather information transmission unit 103.

  The weather information acquisition unit 101 acquires the current weather information of the area from the weather observation device 108. The transmission time interval setting means 102 sets a weather beacon transmission time interval based on weather information. The weather information transmitting means 103 wirelessly transmits a weather beacon related to current weather information at transmission time intervals.

  A specific example of the weather observation apparatus 108 is the weather observation apparatus 25 (FIG. 2). The weather information includes, for example, rainfall, temperature, wind direction, wind speed, atmospheric pressure, and / or humidity as the weather items. Weather beacons are typically transmitted in packet form. The weather beacon typically includes the weather station 100 ID and / or current location information in addition to the weather information.

  By adjusting the transmission time interval of the weather beacon according to the weather information, that is, according to the weather situation, the weather beacon receiving side can accurately grasp the change of the weather situation in the weather station 100 and can control the air traffic. Can be reduced.

  Preferably, the transmission time interval setting means 102 sets a weather beacon transmission time interval based on the value of the weather item included in the weather information. The weather items used for setting the transmission time interval of the weather beacon need not be all weather items included in the weather information.

  Preferably, the transmission time interval setting means 102 sets the transmission time interval to be shorter when it is determined that the change in the value of a predetermined weather item is fast than when it is determined that the value is late. This is because it is desired to observe the weather item more frequently and report the observed value to the weather information receiving station 120 (FIG. 9), which will be described later, as the value changes more severely. In FIG. 4, the transmission time interval is switched based on the reference value for all weather items. For example, in the range of −5 ° C <air temperature <35 ° C., the transmission time interval is minimized. Have not switched to the ones. “The transmission time interval setting unit 102 sets the transmission time interval to be shorter when it is determined that the change in the value of a predetermined weather item is faster than when it is determined to be late”. As for air pressure and humidity, regardless of the range in FIG. 4, that is, even if the range is −5 ° C <temperature <35 ° C. It is.

  Preferably, the transmission time interval setting means 102 sets the transmission time interval to be shorter when it is determined that the value of the predetermined weather item is within the caution range than when it is determined as the non-caution range. The attention range corresponds to the range shown in FIG. 4 (for example, 5 mm or more for rainfall and −5 ° C. or less or 35 ° C. or more for temperature). The attention range generally corresponds to a value range in bad weather. This is because even if the change in the value is small, it is meaningful to observe the observation value finely and report it to the meteorological information receiving station 120 (FIG. 9) described later in bad weather. If the instantaneous rainfall does not change, but continues a large value of 20 mm / h, for example, it is desirable to shorten the transmission time interval and report this to the post-meteorological information receiving station 120.

  In the meteorological station 20 as a specific example of the meteorological station 100, if at least one of a plurality of weather items included in the meteorological information is in a range corresponding to the shortest transmission time interval, the weather information packet transmission time interval is uniformly shortened. However, the Meteorological Bureau 100 is not limited to this, and the values of all the predetermined weather items among all the weather items included in the weather information are included in the corresponding range of each weather item. If so, the weather beacon transmission time interval may be shortened.

  In the meteorological station 20 as a specific example of the meteorological station 100, the transmission time interval of the meteorological information packet is selected from three items of 5 minutes, 10 minutes, and 30 minutes. The transmission time interval may be changed at a stage different from the three stages, or may be changed continuously instead of stepwise.

  FIG. 9 is a block diagram of the weather information receiving station 120. A specific example of the weather information receiving station 120 is the weather information receiving station 15. The weather information receiving station 120 includes a weather beacon receiving unit 121, a determining unit 122, and a warning unit 123. The weather beacon receiving unit 121 wirelessly receives a weather beacon from the weather station. The determination unit 122 determines whether the value of the weather item included in the weather beacon is within the warning range. The warning unit 123 issues a warning when the determination by the determination unit 122 is positive.

  Warnings include visual and audible ones. Typically, the weather beacon receiving means 121 receives the weather beacon in the weather information packet format. A specific example of the warning range is the warning range described in FIG. 4 regarding the rainfall, temperature, wind direction, wind speed, atmospheric pressure, and humidity.

  Thus, in the weather information receiving station 120, the user can smoothly notice important weather information by warning.

  Preferably, the warning means 123 is more emphasized when the weather item value is in the warning range on the weather information interrupt screen displayed on the display unit when the weather information is received from the weather station than when the weather item value is out of the warning range. The weather item value is displayed. A specific example of the highlight display is the blinking display for the temperature in FIG. The highlighting includes, in addition, bold text, color change, size increase, arrowed display, and / or specific display location.

  When the determination by the determination unit 122 is positive, the warning unit 123 outputs a sound different from the normal interrupt sound when the weather information interrupt screen is displayed. In the weather information receiving station 15 as a specific example of the weather information receiving station 120, the normal interrupt sound when the weather information interrupt screen is displayed is the beep sound described in S86 of the weather information display routine 80 of FIG. The sound different from the normal interruption sound may be a sound larger than a normal beam sound, a high sound, a sound of a different tone, or a performance sound.

  The determination means 122 sets only the value of the weather item of the weather information from the weather station in a predetermined area as a determination target. The specific area is a specific example of the meteorological information receiving station 120, and the meteorological information receiving station 15 is an area within 10 km from the own station. The predetermined area in the weather information receiving station 120 is not limited to this, and may be, for example, an area range in which the user of the weather information receiving station 120 is interested.

  FIG. 10 is a flowchart of the weather station control method 130. In S131, the current weather information of the area is acquired from the weather observation apparatus 108. In S132, a weather beacon transmission time interval is set based on the weather information. In S133, the weather beacon according to the current weather information is transmitted wirelessly at every transmission time interval.

  The processes of S131 to S133 correspond to the functions of the weather information acquisition unit 101 to the weather information transmission unit 103 of the weather station 100 (FIG. 8), respectively. Therefore, the specific aspect described about the function of the weather information acquisition means 101-the weather information transmission means 103 is applicable also as a specific aspect about the process of S131-S133.

  FIG. 11 is a flowchart of the weather information receiving station control method 140. In S141, weather information is received wirelessly from the weather station. In S142, it is determined whether or not the value of the weather item included in the weather information is within the warning range. If the determination is positive, the process proceeds to S143. If not, the weather information receiving station control method 140 is set. finish. In S143, a warning is given.

  The processes of S141 to S143 correspond to the functions of the weather beacon receiving unit 121 to the warning unit 123 of the weather information receiving station 120 (FIG. 8), respectively. Therefore, the specific mode described for the functions of the weather beacon receiving unit 121 to the warning unit 123 can be applied as a specific mode for the processing of S141 to S143.
