Description

  The present invention relates to a spraying management system for spraying material on a road surface, and more particularly to a spraying management system for remotely managing spraying work information by a self-propelled working machine. In addition, the spraying material to a road surface as used in this application points out anti-skid materials, such as antifreezing agent (snow melting agent), sand, and crushed stone.

  In cold snowy areas, freezing on road surfaces in winter induces slip accidents, so anti-freezing measures and anti-slip measures are very important for ensuring traffic safety. As anti-freezing measures and anti-slip measures for road surfaces, a method of spraying anti-freezing agents such as sodium chloride and anti-slip materials such as sand and crushed stone is often used.

  Sprinkling materials such as the above-mentioned antifreezing agents and anti-slip materials are sprayed on intersections, road curve areas, bridges, etc. using a self-propelled working machine (spreading vehicle) dedicated to spraying. This spraying work needs to be completed before the commuting time when the traffic volume increases, so multiple work machines are dispatched all at once, and the spraying work is performed at each spraying place (where spraying material needs to be sprayed). Is going.

In addition, in order to perform effective and efficient spraying of antifreeze suitable for road conditions, weather conditions, etc., the working machine (dispersing vehicle) has a function of detecting the position of its own machine (own vehicle) using GPS. A memory card storing a road condition pattern database that holds road condition patterns and scatter condition data is loaded, and the scatter condition data set in the detected road pattern at the position of the aircraft is read from the memory card and read. A technique is known in which a spraying device is controlled by a controller in accordance with the spraying conditions and the antifreezing agent is sprayed automatically (see Patent Document 1).
JP 11-256542 A

  However, the technique shown in the above Patent Document 1 is a technique for each work machine to individually and effectively spray an antifreeze agent. It is not a technology that is centrally managed by a management center.

  Regarding grasping of spraying work of spraying materials such as anti-freezing agents and anti-slip materials, at present, the data (workers) of work machines (spraying vehicles) is recorded in the work diary, etc., and reports of workers Because it relied on the memory of the workers, it was difficult to know exactly when and where the antifreeze or antislip material was sprayed. It was. For this reason, there have been problems such as occurrence of places where the user has forgotten to spray or cases where the same places are scattered twice. In addition, in snowy cold areas, a technology that manages the work status of a large number of snowplows at a management center is known, but the work status with snowplows can be seen at a glance depending on whether or not snow is being removed, so the same It is impossible to remove snow twice in a place.

  Recently, non-chloride type anti-freezing agents have been put into practical use, but as anti-freezing agents, anti-freezing agents using chlorides are mainly used at present due to cost considerations. However, since chloride has problems such as plant depletion and concrete corrosion, it must be used in an appropriate amount.

  Furthermore, the cryoprotectant has a function duration that varies depending on the type of the cryoprotectant, such as those having a function duration of about 6 to 8 hours to about 10 days to 2 weeks. Depending on the situation, it is necessary to spray at an appropriate timing.

  The present invention has been made in view of the above points, and the object of the present invention is to make it possible to centrally and accurately manage the spraying work state by a plurality of work machines that spray the spraying material, and thus In addition, you can check the spray work history on the map, manage the amount of antifreezing agent used according to each spraying location, and manage the proper spraying timing according to the function duration of the antifreezing agent There is to do. Further, an object of the present invention is to make it possible to reliably collect the information on the scatter work from the work machine in real time without imposing a burden on the worker (driver) of the work machine. .

In order to achieve the above-described object, the present invention is directed to a road surface including a self-propelled work machine that performs a work of spreading a spray material on a road surface, and a management device that manages a work state of the work machine. In the spraying management system for the spraying material, the work machine includes a positioning means for detecting the current position of the own machine, a work state detecting means for detecting whether or not the spraying work for spraying the spraying material, Spreading amount detection means for detecting the amount of sprayed material from the start of work to the present, communication means for transmitting information to the management device, identification code of own machine, current position of own machine and start of work at predetermined timing And control means for performing control for transmitting to the management device by means of the communication means spraying work information including the amount of sprayed material from the present to the present. The management device is transmitted from the work machine. Communication to receive information Work map information in which predetermined information is added to the map based on the stage, information storage means for sequentially storing the dispersion work information transmitted from the work machine, and the dispersion work information stored in the map information and the information storage means Control means having a function of creating a management device, the control means of the management device manages the application date and time, the application amount, etc. for each application location based on the application work information stored in the information storage means, at least a map It is configured to create work map information with the scatter work history information added thereto.
Further, the control means of the work machine recognizes that the work state detection means has shifted from the spraying work to the spraying work stop, and uses this recognition as a trigger to instruct the transmission of the spraying work information to the management device. Configured.
Further, the work machine has a spray material type input unit for specifying the type of the spray material, and the control unit of the work machine transmits the spray material type information included in the spray work information to the management device. The control means of the management device is configured to manage the spraying date and time, the type of spraying material, and the spraying amount for each spraying place.
In addition, the control means of the management device compares the spraying date and time for each spraying place with the function duration of the spraying material used for spraying based on the spraying work information stored in the information storage means, and the function duration has elapsed. When there is a spraying place, the work map information is created by adding data indicating that the place needs to be sprayed on the map.

According to the present invention, each work machine transmits, to the management device, spraying work information including the identification code of the own machine, the current position of the own machine, and the amount of sprayed material spread from the start of work to the present at a predetermined timing. Therefore, the management device side can accurately manage the spraying work status of each work machine in a lump sum, and therefore the spraying work history on the map shows whether or not the spraying work has been carried out at each spraying place. It is possible to reliably monitor by displaying the data. In addition, on the management device side, it is possible to appropriately instruct which place and when should be sprayed next, according to the spraying work history of which place, when and how much sprayed. The cumulative amount of spraying at each spraying location can also be grasped, so it is possible to manage the amount of cryoprotectant used appropriately for each spraying location, taking into account the environmental impact of cryoprotectants using chloride. Can be done.
Further, when the work machine control means recognizes that the work state detection means has shifted from the spray work to the spray work stop, the work machine control means transmits the work work information to the management device as a trigger. By simply switching the spraying lever from spraying to spraying stop, the worker (driver) automatically transmits the spraying work information, and there is no burden on the worker for the transmission of spraying work information. And when the spraying in a certain place is completed, it is possible to transmit the spraying work information in real time.
In addition, it is possible to specify the type of the spray material by the spray material type input means operated when the spray material is loaded on the work machine, and the control means of the work machine includes the type information of the spray material in the spray work information. Therefore, the management device can grasp and manage the application date and time, the type of application material, and the application amount for each application location. The next spraying instruction can be given at the timing.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIGS. 1-8 is related with the dispersion | distribution management system of the spreading material to the road surface by one Embodiment (henceforth this embodiment) of this invention, FIG. 1 is explanatory drawing which shows the outline | summary of the whole system.

  In FIG. 1, 1 is a self-propelled working machine (spreading vehicle) dedicated to spraying spray material (freezing agent or anti-slip material) on the road surface, and 2 is described later from a plurality of work implements 1. The management server 3 that collects and manages the distribution work information to be performed is a management terminal that exchanges information with the management server 2, and the management server 2 and the plurality of management terminals 3 constitute a management-side system A. Here, the management server 2 is provided in units of municipalities or wards, for example, and the management terminal 3 is provided in each work division area to which each work machine 1 belongs. Note that the administrative unit and the work division unit in which the management server 2 and the management terminal 3 are installed are arbitrary, and in some cases, a hardware configuration in which the functions of the management server 2 and the management terminal 3 are integrated may be used.

  The work machine 1 is equipped with a GPS (Giobal Positioning System) unit 11, a communication unit 12, a control unit 13, etc., and the GPS unit 11 receives a signal from the GPS satellite 4 under the control of the control unit 13. By doing so, the current position of the own device (own vehicle) is measured, and the communication unit 12 performs information communication with the management server 2 through the public wireless communication network 5. The management server 2 performs information communication with the management terminal 3 through the Internet 6. The communication between the management server 2 and the management terminal 3 may be performed using a dedicated communication line, the public wireless communication network 5 or the like.

  FIG. 2 is an explanatory diagram showing a configuration of the work machine 1, and the work machine 1 is, for example, a machine in which a truck bed is modified and provided with a spraying device. In this work machine 1, in addition to the GPS unit 11, the communication unit 12, and the control unit 13, a work state detection means 14 for detecting an operation state of a spraying operation lever (not shown) provided in the driver's seat, and a work state detection Based on the signal from the means 14 and the timing information, the spread amount detection means 15 for detecting the spread amount of the spread material from the start of the spreading work to the present time, and for example, a multi-position type rotation for specifying the type of the spread material Dispersing material type input means 16 such as a switch is provided.

  The spray material type input means 16 is switched in advance when the spray material is loaded on the work machine 1, and the switching state of the spray material type input means 16, that is, the type of the spray material is identified by the control unit 13. It has become. The work state detection means 14 controls a signal indicating that a spraying operation is being performed when a worker (driver) operates a spraying operation lever (not shown) provided in the driver's seat and starts spraying the sprayed material. When the operator operates the spraying operation lever to stop the spraying of the sprayed material, a signal indicating that the non-spraying work is being performed is output to the control unit 13. . When the spread amount detecting means 15 recognizes that the spread of the spread material has been started by the signal from the work state detecting means 14, it starts the measurement process of the spread amount, and the spread amount per unit time given in advance, Based on the timing information from the start of spraying to the present time, the spray amount of the spray material from the start of spraying to the present is calculated, and this is sequentially updated and stored. Sprinkling amount information is acquired. Further, when the spread amount detecting means 15 recognizes that the spraying of the spread material has been stopped by the signal from the work state detecting means 14, it stops the spread amount measuring process and receives a data transmission request from the control unit 13. When the spread amount information is transmitted, the contents of the memory are cleared.

  If the spraying lever (not shown) can be operated in multiple stages and the spraying amount per unit time varies depending on the switching position of the spraying lever, the spraying amount detection means 15 The spray amount measurement process is performed using the spray amount per unit time according to the switching position. It should be noted that the function of the spray amount detection means 15 may be assigned to the control unit 13. In addition, when an electric signal is directly output by operating a spraying operation lever (not shown), the function of the work state detection means 14 may be assigned to the control unit 13.

  In the work machine 1 described above, when a worker (driver) operates a spraying operation lever (not shown) to start spraying sprayed material (the lever operating state during spraying is hereinafter referred to as an ON state), the working state A signal indicating that the spraying lever is in the ON state is sent from the detecting means 14 to the control unit 13 and the spraying amount detecting means 15, respectively, and the control unit 13 recognizes that the spraying work has started, and sprays. The quantity detection means 15 starts the measurement process of the application quantity. While the spraying lever is in the ON state, the control unit 13 recognizes that the spraying operation is being performed, and the spraying amount detection means 15 continues the processing for measuring the spraying amount. When the spraying operation at a specific place, for example, at an intersection, is finished, the spraying operation lever (not shown) is operated by an operator (driver) to stop the spraying of the sprayed material (the lever operation at the time of stopping the spraying) The state is hereinafter referred to as an OFF state), and a signal indicating that the spraying lever is in the OFF state is sent from the work state detection unit 14 to the control unit 13 and the spraying amount detection unit 15, respectively. Recognizing that the spraying operation has been stopped, the spray amount detection means 15 stops the spray amount measurement process. The control unit 13 acquires the type information of the spray material from the spray material type input means 16 and the spray amount information from the spray quantity detection means 15 at the timing when it has been recognized that the spraying operation has been shifted to the stop of spraying, Further, the GPS unit 11 is operated to acquire current position information of the own device. Then, the control unit 13 creates spraying work information in which the identification code of the own machine and the current date / time information are added to the acquired type information, spread amount information, and current position information of the own machine. Then, the created scattering work information is transmitted to the management server 2 via the public wireless communication network 13 using the communication unit 12.

  FIG. 3 schematically shows the contents of the spraying work information created by the control unit 13 of the work machine 1, and the spraying work information includes own machine identification code D1, date / time information D2, position information D3, spraying material. Type information D4 and spread amount information D5. Regarding the date / time information D2 in the scattering work information, the management server 2 that has received the transmission of the scattering work information can also recognize the date / time at the reception timing of the scattering work information. -The time information D2 may be omitted.

  FIG. 4 is a flowchart showing the flow of processing by the control unit 13 of the work machine 1 and the like. First, it is determined whether or not a spray operation lever (not shown) is in an ON state (step S1), and when the spray operation lever is in an ON state (YES determination in step S1), a spray amount measurement process is started ( Step S2) While the spraying lever is in the ON state (during NO determination in Step S3), the spraying amount measurement process is continued, and when the spraying control lever shifts to the OFF state (YES in Step S3) Then, the process proceeds to step S4. In step S4, as described above, the type information of the spread material, the spread amount information, and the current position information of the own machine are acquired, and the process proceeds to step S5. In step S5, the spraying work information is created by adding the identification code of the own machine and the current date / time information to the acquired type information, spread amount information, and current position information of the own machine. The scattering work information is transmitted to the management server 2.

  FIG. 5 is a block diagram showing the configuration of the management server 2. The management server 2 includes a control device 21 that controls the overall management server 2, a communication control unit 22 that performs data communication with the communication unit 12 and the management terminal 3 of the work machine 1 through the public wireless communication network 5 and the Internet 6. A database 23 for storing various data, an input device 24 such as a keyboard and a mouse, and a display device 25 such as a liquid crystal display are included. The control device 21 actually performs various arithmetic processes, search processes, display control processes, and the like based on various programs and instruction inputs that are developed and executed in an appropriate work area. For convenience of explanation, it is assumed that a work map information creation unit 21a, a scatter history search unit 21b, and a scatter required place search unit 21c are provided. The database 23 is composed of a large-capacity storage device, and a scattered work information database 23a that sequentially stores the scattered work information transmitted from each work machine 1, and a map of an area in which at least the management server 2 is in charge. The map information database 23b that stores the detailed data and the spray material information database 23c that stores the function duration for each of the various spray materials are provided.

  FIG. 6 is a diagram schematically showing an example of the stored contents of the scattering work information database 23 a of the database 23. As shown in FIG. 6, in the scatter work information database 23a, the work position D12 indicated by latitude / longitude and the year / month / day / hour / minute are shown in association with the vehicle NoD11 corresponding to the identification code of the work machine 1. The spraying date and time D13, the type name D14 of the spraying material, and the spraying amount D15 are sequentially stored.

  In the present embodiment, the control device 21 of the management server 2 refers to the contents of the database 23, performs various calculations and search processes, and creates work map information to which information on the distribution history is added on the map. Then, work map information to which information indicating a necessary spray location is added is created on the map, and the created work map information is displayed on the display device 25 of the management server 2 or transferred to the management terminal 3. The creation of the work map information is performed by a request from the management terminal 3, or the management server 2 is automatically executed at a predetermined timing according to a predetermined algorithm.

  FIG. 7 shows a display example on the display of the management terminal 3. When the operator of the management terminal 3 desires to search the distribution history of the spray material in the work division area in charge, first, the history search sub-screen Rs1 is called on the display of the management terminal 3, and in the history search sub-screen Rs1, Enter the type of material and the period you want to display and instruct the search. This search instruction is transmitted to the management server 2 through the Internet 6. In response to this, the management server 2 specifies the work division area handled by the terminal device 3 from the URL (Uniform Resource Locator) of the management terminal 3 that has instructed the search request, and the scatter history search unit 21b is specified. In the work division area, data corresponding to the spray history according to the search instruction content (spray material type, search period) from the management terminal 3 is searched from the spray work information database 23a. The distribution history information searched in the scatter work information database 23a is transferred to the work map information creation unit 21a. The work map information creation unit 21a reads the map information of the identified work division area from the map information database 23b, The work map information is created by adding the distribution history information searched by the distribution history search unit 21b to the read work division area map. The created work map information is transmitted from the communication control unit 22 to the management terminal 3 that has instructed the search request via the Internet 6. In response, the work map information indicated by M1 is displayed on the display of the management terminal 3. The work map information M1 shown in FIG. 7 shows an example in which 10 places P1 to P10 are displayed as places where the scattering has been performed.

  By the search instruction using the history search sub-screen Rs1 as described above, the place where the spraying has been performed in the past predetermined period can be surely displayed on the map, and the spraying material can be specified. By displaying the spraying history of a specific spraying material and the spraying history of all types of spraying material on a map, the spraying history of a desired form can be easily and reliably grasped. Therefore, for example, if the application status of all application materials from the present to 6 days ago is searched and the location where the application material is applied is displayed on the map between the present and 6 days before, once every 6 days In addition, it is possible to grasp a place where spraying is not performed, and to issue an instruction so as to focus on the place where spraying is not performed.

  In addition, there are anti-freezing agents and anti-slip materials in the spray material, and the spray material is generally used properly depending on the temperature and road surface conditions. Specifically, the antifreezing agent is effective at -8 degrees or more, and the anti-slip material is effective at -8 degrees or less. Therefore, in the history search sub-screen Rs1, by selecting the type of the spraying material and performing the search, the spraying history for each spraying material can be grasped when the spraying material is properly used depending on the temperature and the road surface condition during the spraying work. It becomes possible to give a spraying work instruction.

  Although not shown, in the display state of the work map information to which the information of the scatter history is added, for example, by specifying an arbitrary scatter location and calling detailed information, It is possible to display the type of spraying material for this season and the cumulative spraying amount for each type in a window so that the type of spraying material for each spraying location and the total amount of spraying for each type can be grasped. It has become. Therefore, for example, in areas where the cumulative amount of chloride antifreeze is applied, an instruction to switch to non-chloride type antifreeze or to reduce the amount of chloride antifreeze applied It is possible to give appropriate spraying work instructions in consideration of the environmental impact.

  FIG. 8 shows another display example on the display of the management terminal 3, and FIG. 8 is an example in which a place where the spraying material needs to be scattered is searched and displayed. When the operator of the management terminal 3 wants to search for a place where the spraying material needs to be sprayed because the function duration of the spraying material sprayed last time has expired in the work division area in charge, first, on the display of the management terminal 3 A necessary spraying place search subscreen Rs2 is called, and on this necessary spraying place search subscreen Rs2, it is selected whether to display only the place, or to display the place / spreading material type / necessary spraying amount, and instruct the search. This search instruction is transmitted to the management server 2 through the Internet 6. In response to this, the management server 2 specifies the work division area handled by the terminal device 3 from the URL of the management terminal 3 that has instructed the search request, and the necessary spray location search unit 21c specifies the work division specified. In the area, a place where the function duration of the sprayed material sprayed last time is exceeded is searched with reference to the contents of the spray work information database 23a and the contents of the spray material information database 23c. When the location where spraying is necessary is not found by the search by the spraying required location searching unit 21c, the control device 21 sends a message indicating that to the management requesting the search request from the communication control unit 22 via the Internet 6. Transmit to terminal 3. If a place where spraying is necessary is found by the search by the spraying place search unit 21c, the spraying place search unit 21c displays the display instruction content from the management terminal 3 (displays only the place or places / scatters). In accordance with the display of the material type and the required spray amount, the calculation of the spray material type and the required spray amount is performed as necessary, and the search place data and the calculation result data are passed to the work map information creating unit 21a. The work map information creation unit 21a reads the map information of the specified work division area from the map information database 23b, and adds the information passed from the necessary distribution place search unit 21c on the read map of the work division area. Create work map information. The created work map information is transmitted from the communication control unit 22 to the management terminal 3 that has instructed the search request via the Internet 6. In response to this, work map information indicated by M2 is displayed on the display of the management terminal 3. The work map information M2 shown in FIG. 8 shows an example in which two locations P5 and P6, and the type of spray material and the required spray amount there are displayed as locations where spraying is necessary.

  In the above-described example, the management server 2 performs a search in response to a request from the management terminal 3 and transmits work map information based on the search result to the management terminal 3. For example, the automatic search may be periodically performed based on the search algorithm, and work map information based on the search result may be generated and periodically transmitted to the management terminal 3.

  In the above-described example, the work machine 1 transmits the scatter work information to the management server 2 when the scatter operation lever is changed from the ON state to the OFF state. Besides, when spraying work is continuing (spraying control lever is in the ON state), when a predetermined time has elapsed since the start of the spraying work, or when a predetermined time has passed since the last transmission of the spraying work information In addition, transmission work information may be transmitted from the work machine 1. Alternatively, when the work machine 1 is moved a predetermined distance from the start of the spraying work or moved a predetermined distance from the previous transmission work information transmission while the spraying work is being continued (spraying operation lever is in the ON state) In addition, transmission work information may be transmitted from the work machine 1.
