Description

  The present invention relates to a snow removal device driving method and a snow removal device control system for removing snow accumulated on a road.

  Groundwater is sprayed on the road during snowfall, and groundwater intake equipment such as wells or submersible pumps, and underground transmissions are used to prevent traffic congestion due to snow accumulation, industrial activity stagnation, or accidents caused by snow removal. A snow extinguishing equipment composed of watering equipment such as water pipes and sprinkling pipes, electric equipment such as a snowfall detector and a control panel is used.

  In order to save energy in such snow-dissipating equipment, the snowfall monitoring area is divided into a plurality of monitoring divided areas, and when snowfall is detected in the snowfall monitoring area, the pump devices in each monitoring divided area are sequentially turned on for a predetermined time. A snow-finging device monitoring control method for driving has been proposed (see Patent Document 1).

  In addition, an observation station such as a snow-melting equipment concentration station and a sluice monitoring station, a management terminal device for managing these observation stations, and a server having an ASP (Application Service Provider) function are connected to a public communication line. , A wide area integrated information collection control system that can collect information on various monitoring targets at low cost by separating the observation data sent from the observation station and sending it to the management terminal device corresponding to the type of observation data (See Patent Document 2).

  Also, a snow melting method is proposed in which a snow melting device that can be removed at a snow melting point is installed, the snow melting device and a management terminal are connected to a communication line, and the operation of the snow melting device is remotely controlled from the management terminal based on snow accumulation information. (See Patent Document 3).

  Also, it has a reception mode in which either a signal from a predetermined snow sensor as a dedicated product or a signal from a snow sensor other than the dedicated product (for example, a snow sensor originally owned by the user) can be switched. Therefore, a snow melting device excellent in flexibility has been proposed (see Patent Document 4).

In addition, in recent snow-melting equipment, a concentration station with one snowfall detector is installed in a relatively wide snow-melting area (melting snow area), and it is composed of a snow-discharging pump, a water pipe, and a water spray pipe. If the snow-breaking device is installed at a distance, and the central office, snow-melting device and monitoring device are connected via a communication line and snowfall is detected, the snow-melting devices in the snow-melting area are driven all at once, It tends to snow.

  When the control unit 42 detects snowfall (start of snowfall) in at least one of the meteorological station 10 or the sub-meteorological station 20 installed in the snow melting region, the control unit 42 detects it in the slave stations 30 installed in the snow melting region. It is determined whether or not the measured temperature (air temperature) is lower than the snowfall temperature, and a control signal is sent to the slave station 30 in order to start driving the snow-pumping pump facility 60 connected to the slave station 30 that detects the temperature lower than the snowfall temperature. Send. Further, in this case, the control unit 42 sends a control signal to the meteorological station 10 or the sub-meteorological station 20 in order to start driving the snow-pumping pump facility 60 connected to the meteorological station 10 or the sub-meteorological station 20 that detects snowfall. Send.

  When all the weather stations 10 and sub-meteorological stations 20 installed in the snow melting region detect snowfall, the control unit 42 is concerned with the temperature (air temperature) detected by the slave stations 30 installed in the snow melting region. First, a control signal is transmitted to all the slave stations 30,. Thereby, all the snow-pumping pump facilities 60 in the snow melting region are put into operation.

  When at least one of the meteorological station 10 or the sub-meteorological station 20 installed in the snow melting region detects the stop of snowfall, the control unit 42 determines whether the meteorological station 10 or the sub-meteorological station 20 is based on the watering plan information 443. A control signal is transmitted to the meteorological station 10 or the sub-meteorological station 20 to stop the corresponding snowpumping pump facility 60 after a predetermined time z has elapsed since the snow stopped.

  If the substation meteorological station 20 detects the stop of snowfall and the meteorological station 10 also detects the stop of snowfall, the control unit 42 obtains the snowfall time a obtained at the meteorological station 10 and the submeteorological station 20. The correction time y corresponding to the time difference (ab) with respect to the snowfall time b (for example, a> b) is calculated. Based on the watering plan information 443, the control unit 42 controls the snowpump pump facility 60 corresponding to the meteorological station 10 to stop after the total time (z + y) of the predetermined time z and the correction time y has elapsed since the snow stopped. Is transmitted to the weather station 10. The correction time y can be the same value as the time difference (ab), or a value obtained by integrating the time difference (ab) with a different required coefficient for each snow melting region can be used. .

  For example, the control unit 42 is a value obtained by dividing the calculated correction time y by N + 1, where N is the number of slave stations 30 installed between the weather station 10 and the sub-meteorological station 20 in the snow melting region. y / (N + 1) is calculated as the stop transition time ΔT of the snow-pumping pump facility 60 corresponding to each slave station 30. The control unit 42 determines a point of time shorter by ΔT from the stop point of the snowplow pump facility 60 corresponding to the meteorological station 10 as a stop point of the snowpump pump facility 60 corresponding to the slave station 30 closest to the meteorological station 10. Similarly, the control unit 42 stops the snow-discharging pump facility 60 corresponding to the second closest slave station 30 from the weather station 10 by a time shorter by 2ΔT from the stopping time of the snow-discharging pump facility 60 corresponding to the weather station 10. Determine as. Hereinafter, similarly, the stop point of the snow-pumping pump facility 60 corresponding to each slave station 30 is determined. When calculating the stop transition time ΔT, the correction time y is not only divided by N + 1, but may be divided by N or may be divided by another value.

  In addition, stop transition time (DELTA) T adds an appropriate coefficient (weight) according to the length of the distance to the weather station 10 or the sub-meteorological station 20 of each slave station 30, and stops transition between the adjacent slave stations 30 It is also possible to determine the time ΔT to a different value. In addition, by determining the same stop transition time ΔT for a plurality of slave stations 30, it is also possible to stop the snow-pumping pump equipment 60 corresponding to the plurality of slave stations 30 at the same time. The stop transition time ΔT can be appropriately determined according to, for example, the weather condition in the snow melting region.

  When receiving an abnormal signal from any of the slave stations 30, the control unit 42 excludes the slave station 30 from the control target. As a result, the central processing unit 40 does not need to communicate with the excluded slave stations 30 and can transmit a control signal only to the slave stations 30 that are operating normally. Can be quickly communicated, and the operation of the snow-melting device can be quickly performed.

  Next, the operation of the snow removal device control system of the present invention will be described. FIG. 5 is a time chart showing an example of the start of operation of the snow removal device. As shown in FIG. 5, it is assumed that a meteorological station, a sub-meteorological station, and slave stations 1, 2, 3, 4 are installed in an arbitrary snow melting region. When snow is detected at the meteorological station, the central processing unit 40 starts the operation of the snow removing device (snow pumping equipment 60) corresponding to the meteorological station.

  The central processing unit 40 determines whether or not the temperature detected at each of the slave stations 1, 2, 3, and 4 is lower than the snowfall temperature. After detecting the snowfall at the Meteorological Bureau, if the temperature detected at the slave station 1 becomes lower than the snowfall temperature (snowfall temperature detection), the operation of the snow removal device (snow pumping equipment 60) corresponding to the slave station 1 is operated. To start. When further time elapses and the temperature detected by the central processing unit 40 at the slave station 2 becomes lower than the snowfall temperature (snowfall temperature detection), the snow removal device (snow pumping equipment 60) corresponding to the slave station 2 is used. Start driving. At this time, the snow temperature is not detected in the slave stations 3 and 4. When further time passes and snow is detected in the sub-meteorological station, the central processing unit 40 is connected to the snow-removing device (snow pump unit 60) corresponding to the sub-meteorological station, and the slave station that has not yet started operation. The operation of the snow removal device (snow removal pump facility 60) corresponding to 3, 4 is started. Note that the example of FIG. 5 is an example, and the method of starting the operation of the snow removal device is not limited to this.

  This makes it possible to start the operation of individual snow-melting devices according to the weather conditions in the snow-melting region, as compared with the case where the snow-melting devices in the snow melting region are started all at once. Therefore, it is possible to economically operate the snow squeezing apparatus by preventing the situation where the ground water and the power are wasted.

  FIG. 6 is a time chart showing an example of the operation stop of the snow removal device. As shown in FIG. 6, it is assumed that a meteorological station, a sub-meteorological station, and slave stations 1, 2, 3, 4 are installed in an arbitrary snow melting region. When the stop of snowing is detected at the sub-meteorological station at time t1 (in this case, the snowing time observed at the sub-meteorological station is b), the central processing unit 40 starts from the time t1 when the stop of snowing is detected. After the predetermined time z has elapsed, the operation of the snow removal device (snow removal pump facility 60) corresponding to the sub-meteorological station is stopped.

  Next, when the stop of snow is detected by the weather station at time t2 (in this case, the snowing time observed by the weather station is a, where a> b), the central processing unit 40 The operation of the snow removal device (snow pumping equipment 60) corresponding to the meteorological bureau is stopped at the time t3 after the total time (z + y) of the predetermined time z and the correction time y has elapsed from the time t2 when the stop of snowfall is detected. To do.

  The central processing unit 40 determines the stop transition time ΔT (in this case, for example, ΔT = y / 5), and the snow removal device (snow removal pump facility 60) corresponding to the slave station 1 at a time earlier by Δt than the time t3. Is stopped, the operation of the snow removal device (snow pumping equipment 60) corresponding to the slave station 2 is stopped at a time that is 2Δt earlier than the time t3, and the slave station 3 is supported at a time that is 3Δt earlier than the time t3. The operation of the snow removal device (the snow removal pump facility 60) is stopped, and the operation of the snow removal device (the snow removal pump facility 60) corresponding to the slave station 4 is stopped at a time earlier by 4Δt than the time t3. Note that the example of FIG. 6 is an example, and the method of stopping the operation of the snow removal device is not limited to this. For example, the value of ΔT can be determined so as to be different between adjacent slave stations depending on the distance of each slave station to the weather station or the sub-meteorological station.

  This makes it possible to stop the operation of individual snow-melting devices in accordance with the weather conditions in the snow-melting region, compared to when the snow-melting devices in the snow-melting region are stopped all at once. Therefore, it is possible to economically operate the snow squeezing apparatus by preventing the situation where the ground water and the power are wasted.

As shown in FIG. 7, a plurality of slave stations 30,..., And a snow extinguishing device are installed at required positions in the snow melting area A so as to surround the snow melting area A (for example, at an appropriate distance). And the meteorological station 10 is installed in three places. Of the three weather stations 10, each set of two weather stations 10 controls the slave stations 30 installed in the areas A <b> 1, A <b> 2, A <b> 3 sandwiched between the two weather stations 10. In addition, the operation start and operation stop methods of the snow removal device in each of the areas A1, A2, and A3 are the same as those in the first embodiment. Thereby, it is possible to carry out snow removal in a wide range of snow melting regions without limiting the arrangement of the snow removal device to a substantially linear shape. Further, the number of weather stations 10 in the snow melting region may be four or more.
