Description

[Technical Field]

[0001] This disclosure relates to an information and communication type distributor and a monitoring system for pavement construction equipped with said distributor. [Background technology]

[0002] An asphalt distributor or distributor is a construction machine that spreads bituminous materials such as asphalt emulsion onto the road surface, and is widely used for spreading tack coat and prime coat. Since the amount of tack coat and prime coat spread affects the properties of the resulting pavement, a predetermined design value is set for the amount to be spread.

[0003] On the other hand, the amount of bituminous material such as asphalt emulsion sprayed by a distributor is usually determined by measuring the weight of the distributor on a weighbridge before and after construction, and calculating the amount based on the difference in weight of the distributor before and after construction. However, with this method based on the difference in weight of the distributor before and after construction, the amount sprayed cannot be known until the construction is completed and the weight of the distributor is measured again, and naturally, the amount sprayed cannot be confirmed during paving work. Currently, on site, the amount of asphalt emulsion sprayed is usually adjusted by the skill of the distributor operator, based on the travel speed of the distributor and the spraying speed of the asphalt emulsion.

[0004] Furthermore, the amount of sprayed using the above method, which calculates the amount based on the weight difference of the distributor before and after construction, is an average value for the entire construction area and does not allow for information on localized areas of excess spraying. Knowing information on localized areas of excess spraying would be extremely useful as a reference for predicting the need for repair work and determining whether inspection work is necessary. In particular, if localized areas of excess spraying could be known in real time, it would be possible to take appropriate measures at the right time, such as spraying additional amounts to compensate for any shortages.

[0005] While monitoring systems for pavement work exist, for example, a system for monitoring construction management parameters in the implementation of roadbed regeneration methods is known (Patent Document 1), no system capable of monitoring pavement work by distributors is known at all. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2022-28629 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] The present invention has been made in view of the problems of the prior art described above, and in one aspect aims to provide an information and communication type distributor capable of monitoring paving work in which bituminous material is sprayed by a distributor, and / or a monitoring system for paving work including the said distributor. [Means for solving the problem]

[0008] In paving work, areas where asphalt emulsion is sprayed include, for example, near the start and end points of the paving work, or near obstacles such as utility poles and manholes, where it is difficult to spray the emulsion using a distributor. In such areas, the asphalt emulsion is sprayed manually using a small spraying device such as a sprayer. From the perspective of monitoring paving work, it is desirable to be able to monitor areas where it is difficult to spray the emulsion using a distributor. However, developing a monitoring system that can simultaneously monitor both the spraying of asphalt emulsion by a distributor and the spraying of asphalt emulsion by manual means has not been easy.

[0009] As a result of intensive research efforts to solve the above problems, the inventors of the present invention have developed a distributor that can switch between a running spraying mode in which asphalt emulsion is sprayed from a spraying means for running spraying and a manual spraying mode in which asphalt emulsion is sprayed from a spraying means for manual spraying according to the construction target section, enabling the selection of a spraying mode for each construction target section, and transmitting monitoring information obtained according to the selected spraying mode to a server on the network, thereby enabling the collective monitoring of the spraying of asphalt emulsion by the distributor and the manual spraying of asphalt emulsion, and completing the present invention.

[0010] That is, in one aspect, the present invention is an information communication type distributor that transmits monitoring information of pavement construction to a server on the network, and a spraying means for asphalt materials for running spraying, a spraying means for asphalt materials for manual spraying, a means for measuring the spraying amount of asphalt materials by the spraying means for running spraying, a means for measuring the spraying amount of asphalt materials by the spraying means for manual spraying, a means for receiving a selection as to whether the construction target section is a running spraying section in which asphalt materials are sprayed by the spraying means for running spraying or a manual spraying section in which asphalt materials are sprayed by the spraying means for manual spraying, and comprises when the construction target section is a running spraying section, spraying asphalt materials from the spraying means for running spraying and transmitting monitoring information including the measured value of the spraying amount of asphalt materials by the spraying means for running spraying to the server, when the construction target section is a manual spraying section, spraying asphalt materials from the spraying means for manual spraying and transmitting monitoring information including the measured value of the spraying amount of asphalt materials by the spraying means for manual spraying to the server, thus solving the above problems by providing a distributor.

[0011] As mentioned above, the areas targeted for paving work involving the application of bituminous material include, for example, areas near the start and end points of the paving work, or near obstacles such as utility poles and manholes, where it is difficult to apply the bituminous material while driving the distributor. According to the distributor described above, which relates to one aspect of the present invention, for sections of the construction area included in the area to be paved, where it is possible to spray by the distributor while it is moving, the driving spraying mode is selected, and bituminous material is sprayed by the driving spraying means while monitoring the measured amount of bituminous material sprayed by the driving spraying means. On the other hand, for sections where it is difficult to spray bituminous material by the distributor while it is moving, the mode is switched to manual spraying mode, and bituminous material is sprayed by the manual spraying means while monitoring the measured amount of bituminous material sprayed by the manual spraying means. As a result, it becomes possible to spray bituminous material and monitor the spraying status all at once, including the parts where bituminous material has conventionally been sprayed manually.

[0012] Furthermore, in another aspect, the present invention solves the above problems by providing a monitoring system for paving work that includes a server and an information and communication type distributor according to one aspect of the present invention. [Effects of the Invention]

[0013] According to one aspect of the present invention, an information and communication type distributor or paving work monitoring system makes it possible to monitor the spraying of bituminous material and its spraying status in a single operation, including areas where it is difficult to spray bituminous material by driving a distributor and where the material has traditionally been sprayed manually.

[0015] The present invention will be described in more detail below with reference to specific examples, but it goes without saying that the present invention is not limited to those illustrated.

[0016] <Distributor> In this disclosure, the term "distributor" refers to an asphalt distributor unless otherwise specified. A distributor is a construction machine used to spread bituminous materials such as asphalt emulsion and cutback asphalt onto the road surface during paving work. Distributors are used, for example, to spread tack coat and prime coat.

[0017] The bituminous material sprayed by the distributor includes, for example, asphalt emulsion, cutback asphalt, and asphalt, but is typically asphalt emulsion. The asphalt emulsion can be any type of asphalt emulsion, including cationic, anionic, or nonionic asphalt emulsions. It may also be a modified asphalt emulsion containing appropriate modifying components.

[0018] Figure 1 is a schematic diagram showing a distributor 100 according to one embodiment of a distributor according to one aspect of the present invention.

[0019] As shown in Figure 1, the distributor 100 is a self-propelled work vehicle, and is equipped with a spray bar 101 at the rear of the vehicle as a means for spraying bituminous material while moving. The spraying means for moving means a means for spraying bituminous material while the distributor 100 is moving. In other words, the spraying means for moving is a means for spraying bituminous material used while the distributor 100 is moving.

[0020] The spray bar 101 for mobile spraying is connected to a heat-insulated tank 103 containing bituminous material via a piping system including a connecting pipe 102, and the bituminous material is supplied from the heat-insulated tank 103 through the connecting pipe 102 to the spray bar 101. The spray bar 101 for mobile spraying is usually located at the rear of the distributor 100, and the spray bar 101 is equipped with a plurality of spray nozzles, which are spaced apart from each other in the width direction of the distributor 100. The bituminous material supplied to the spray bar 101 is discharged from the spray nozzles provided on the spray bar 101. Thus, in one preferred embodiment, a distributor according to one aspect of the present invention may be configured as a spraying means for mobile spraying, comprising a spray bar for mobile spraying, more specifically a spray bar equipped with spray nozzles for mobile spraying.

[0021] The distributor 100 is an air-pressurized distributor and is equipped with a compressor (not shown). That is, the distributor 100 is configured to spray the bituminous material using the air pressure of the compressor. However, the distributor according to one aspect of the present invention does not necessarily have to be an air-pressurized distributor; for example, it may be a gear pump type distributor.

[0022] Each spray nozzle may be equipped with a nozzle on / off valve, and the discharge of bituminous material from each spray nozzle may be changed by opening or closing the nozzle on / off valve. The nozzle on / off valve may be configured to be opened and closed manually, or it may be configured to be opened and closed remotely from the driver's seat of the distributor or the like. If each spray nozzle is equipped with a nozzle on / off valve, the spray width of the bituminous material can be appropriately changed by operating the nozzle on / off valve to adjust the number of spray nozzles that are in the open state.

[0023] Furthermore, in the distributor 100, a flow meter 104 is attached to a connecting pipe 102 provided in the piping that connects the spray bar 101 for mobile spraying and the insulated tank 103 in which the bituminous material is stored, so that the flow rate of the bituminous material passing through the connecting pipe 102 can be measured. Thus, in one preferred embodiment, the distributor according to one aspect of the present invention is equipped with means for measuring the amount of bituminous material sprayed from the spraying means for mobile spraying.

[0024] The bituminous material passing through the connecting pipe 102, which is installed in the piping connecting the mobile spraying sprayer 101 and the heat-insulating tank 103, is discharged from the mobile spraying sprayer 101 (more specifically, from the spraying nozzles of the mobile spraying sprayer 101). Therefore, the amount of bituminous material discharged from the mobile spraying sprayer 101, which is a mobile spraying means, can be measured based on the flow rate of the bituminous material measured by the flow meter 104 attached to the connecting pipe 102. The flow meter that may be provided in a distributor according to one aspect of the present invention can be basically any type as long as it can measure the flow rate of the bituminous material passing through the connecting pipe, but for example, it may be an electromagnetic flow meter.

[0025] Furthermore, the distributor 100 is equipped with a spray bar 105 for manual spraying on the rear side of the vehicle, as a means of manual spraying. The means of manual spraying refers to a means of spraying bituminous material when the distributor 100 is stopped. In other words, the means of manual spraying is a means of spraying bituminous material used when the operator manually sprays the bituminous material while the distributor 100 is stopped.

[0026] A spray bar 105 for manual spraying is connected to a heat-insulated tank 103 containing bituminous material via a piping system including a connecting pipe 106, and the bituminous material is supplied from the heat-insulated tank through the connecting pipe 106 to the spray bar 105. The spray bar 105 is provided with at least one spray nozzle, and the bituminous material supplied to the spray bar 105 is configured to be discharged from this spray nozzle. Thus, in one preferred embodiment, a distributor according to one aspect of the present invention may be configured as a spraying means for manual spraying, comprising a spray bar for manual spraying, more particularly a spray bar equipped with a spray nozzle for manual spraying.

[0027] There are no particular restrictions on the specific configuration of the spraying means for manual spraying, but it is preferable that it be configured to be portable around the distributor while connected to the distributor, so that the operator can manually spray the bituminous material when the distributor is stopped. For example, the piping connecting the spray bar 105 for manual spraying and the insulated tank 103 may be configured to include a hose 107, as in the distributor 100. When the piping connecting the spray bar for manual spraying and the insulated tank includes a hose, the operator can carry the spray bar for manual spraying around the distributor.

[0028] There are no particular restrictions on the number of spray nozzles that a spray bar for manual spraying can have, but typically there are one to two, or usually one. Each spray nozzle may be fitted with a nozzle on / off valve, and this nozzle on / off valve may be made open and / or remotely operated, as described for spray nozzles on a spray bar for mobile spraying.

[0029] Furthermore, in the distributor 100, a flow meter 108 is attached to a connecting pipe 106 provided in the piping that connects the spray bar 105 for manual spraying and the insulated tank 103 in which the bituminous material is stored, so that the flow rate of the bituminous material passing through the connecting pipe 106 can be measured. Thus, in one preferred embodiment, the distributor according to one aspect of the present invention is equipped with means for measuring the amount of bituminous material sprayed from the spraying means for manual spraying.

[0030] The bituminous material passing through the connecting pipe 106, which is installed in the piping connecting the manual spraying spray bar 105 and the heat-insulating tank 103, is discharged from the manual spraying spray bar 105 (more specifically, from the spraying nozzles of the manual spraying spray bar 105). Therefore, the amount of bituminous material discharged from the manual spraying means can be measured based on the flow rate of the bituminous material measured by the flow meter 108 attached to the connecting pipe 106. The flow meter can be basically any type as long as it can measure the flow rate of the bituminous material passing through the connecting pipe, but for example, it could be an electromagnetic flow meter.

[0031] Furthermore, the distributor 100 is equipped with a control computer 109, which includes a touch panel (not shown) as a display means for displaying a screen containing various information and an input receiving means for receiving input of various information.

[0032] In the distributor 100, for each section to be constructed, the system can accept a selection from an input screen displayed on the touch panel whether the section to be constructed is a mobile spraying section or a manual spraying section. In other words, in the distributor 100, the means for accepting a selection as to whether the section to be constructed is a mobile spraying section in which bituminous material is sprayed by a mobile spraying means, or a manual spraying section in which bituminous material is sprayed by a manual spraying means, includes a control computer 109 and a touch panel provided on the control computer 109.

[0033] Furthermore, the distributor 100 is configured such that, for example, when the area to be worked on is selected as either a mobile spraying area or a manual spraying area, the spraying mode of the distributor 100 is switched. For example, when the touch panel of the control computer 109 selects whether the area to be worked on is a mobile spraying area or a manual spraying area, the system may be configured such that, based on the signal input to the control computer 109 via the touch panel, solenoid valves and spray nozzles (not shown) provided in the piping of each spraying means open and close, and the spraying mode is switched to the selected spraying mode. However, the means for switching the spraying mode according to the selection of whether the area to be worked on is a mobile spraying area or a manual spraying area is not limited to the above. For example, the system may be configured such that the spraying mode is selected from a spraying mode switch provided in a predetermined part of the distributor, such as the driver's seat, and the spraying mode is switched based on an input signal corresponding to the selected spraying mode.

[0034] The distributor 100 measures the amount of bituminous material sprayed from the spraying means for mobile spraying when the construction target section is a mobile spraying section, in other words, when the spraying mode is mobile spraying mode, and transmits monitoring information including the obtained measurement value to a predetermined server. When the construction target section is a mobile spraying section, the distributor 100 may stop or continue measuring the amount of bituminous material sprayed from the spraying means for manual spraying. Also, when the construction target section is a mobile spraying section, the measurement value of the amount of bituminous material sprayed from the spraying means for manual spraying may or may not be included in the monitoring information. If the construction target section is a mobile spraying section, and the monitoring information transmitted to the server includes both the amount of bituminous material sprayed from a mobile spraying device and the amount of bituminous material sprayed from a manual spraying device, the server may distinguish between the amount of bituminous material sprayed from a mobile spraying device and the amount of bituminous material sprayed from a manual spraying device by, for example, associating the flow meter identification information with the amount of bituminous material sprayed measured by the flow meter.

[0035] On the other hand, if the construction target section is a manual spraying section, in other words, if the spraying mode is set to manual spraying mode, the distributor 100 measures the amount of bituminous material sprayed from the manual spraying means and transmits monitoring information including the obtained measurement value to a predetermined server. If the construction target section is a manual spraying section, the distributor 100 may stop or continue measuring the amount of bituminous material sprayed from the mobile spraying means. Also, if the construction target section is a manual spraying section, the measurement value of the amount of bituminous material sprayed from the mobile spraying means may or may not be included in the monitoring information. If the section to be constructed is a manually sprayed section, and the monitoring information transmitted to the server includes both the amount of bituminous material sprayed from a mobile spraying device and the amount of bituminous material sprayed from a manually spraying device, the server may distinguish between the amount of bituminous material sprayed from a mobile spraying device and the amount of bituminous material sprayed from a manually spraying device by, for example, associating the flow meter identification information with the amount of bituminous material sprayed measured by the flow meter.

[0036] In one preferred embodiment, the amount of bituminous material sprayed is preferably measured at predetermined time intervals, and more preferably at predetermined time intervals synchronized with location information, which will be described later. Here, the predetermined time interval synchronized with location information may mean the same time interval at which the location information is acquired. In other words, the location information and the amount of bituminous material sprayed can most preferably be measured simultaneously or substantially simultaneously. When the amount of bituminous material sprayed is measured at predetermined time intervals, it is very convenient because the change in the amount of bituminous material sprayed over time can be monitored. Furthermore, by summing the amount sprayed up to a certain point in time, the cumulative amount of bituminous material sprayed can also be determined. In addition, when the amount of bituminous material sprayed is measured at predetermined time intervals synchronized with location information, it is possible to understand when, where, and how much bituminous material was sprayed, so for example, it is possible to understand the amount of bituminous material sprayed per unit area at a certain location, or the spraying speed of the bituminous material.

[0037] Furthermore, the distributor 100 is equipped with a positioning antenna 110 that receives radio signals from a positioning system as a means of measuring the location information of the distributor 100. The positioning system used can be any system that can measure the current location of the distributor 100 at regular time intervals, and is not limited to any particular system, but for example, a Global Navigation Satellite System (GNSS) is preferably used, and among these, RTK-GNSS using the RTK method, which enables particularly high-precision positioning, can be preferably used. The positioning antenna may be attached to any position on the distributor 100, but for example, it may be attached to the rear of the vehicle of the distributor 100, close to the spray bar where the bituminous material is sprayed.

[0038] The positioning signal received by the positioning antenna 110 is transmitted to the control computer 109. Based on the received positioning signal, the control computer 109 acquires the position information of the positioning antenna 110, and more specifically, the latitude and longitude information of the positioning antenna 110. In the case of RTK-GNSS, positioning signals are transmitted at 1-second intervals, and by receiving these signals with the positioning antenna, the control computer 109 can acquire the position information of the positioning antenna 110, and more specifically, the longitude and latitude information, at 1-second intervals. For example, let t0 be the start time for acquiring latitude and longitude information, and t1, t2, t3, ... t be the time for each subsequent unit of time. n Therefore, the position information (longitude and latitude) of the positioning antenna 110 at each time point is P0, P1, P2, P3, ...P n This will be required. Thus, in one preferred embodiment, a distributor according to one aspect of the present invention may be equipped with means for measuring the location information of the distributor, more preferably means for measuring the location information of the distributor at predetermined time intervals.

[0039] Further, in a certain preferred aspect, the distributor according to one aspect of the present invention may include means for acquiring the speed of the distributor at a predetermined time interval. The speed of the distributor 100 at a predetermined time interval can be obtained, for example, based on position information measured at the predetermined time interval. Although merely an example, for instance, at times t0, t1, t2, t3, ··· t n the measured values of the position information of the distributor 100 at are taken as P0, P1, P2, P3, ··· P n Then, the speeds V1, V2, V3, ··· V n of the distributor 100 at times t0, t1, t2, t3, ··· t n can be estimated, for example, in the control computer 109 by executing the following calculation formula: V1 = |P1 - P0| / (t1 - t0) V2 = |P2 - P1| / (t2 - t1) ··· V n = |P n - P n-1 | / (t n - t n-1 ) However, the method for obtaining the speed of the distributor 100 is not limited to the above calculation formula, and an appropriate method can be used according to the accuracy of the required information, etc. Further, the distributor 100 may, if necessary, utilize a server described later to acquire the speed of the distributor 100 at a predetermined time interval. For example, by receiving the speed of the distributor 100 obtained, such as by executing the above calculation formula in the server, it may be provided with means for acquiring the speed of the distributor 100.

[0040] Furthermore, while the above specifically describes a means for acquiring the speed of the distributor 100 at predetermined time intervals based on the position information of the distributor 100 measured by RTK-GNSS, the method for acquiring the speed of the distributor 100 is not limited to this. For example, the distributor 100 may be equipped with a speed sensor, and the speed of the distributor 100 may be acquired at predetermined time intervals based on the signal acquired by the speed sensor. As a signal for measuring the speed of the distributor 100, for example, a pulse signal that can be converted to the speed of the distributor 100, such as a pulse signal proportional to the amount of rotation of the axle of the distributor 100, can be measured.

[0041] Furthermore, the distributor 100 is equipped with flow meters 104 and 106, and the control computer 109 receives measured values ​​of the flow rate of bituminous material per unit time from the flow meter 104 or 106 at predetermined time intervals synchronized with the positioning signal from RTK-GNSS, depending on the spraying mode, etc. That is, the control computer 109 receives the amount of bituminous material per unit time Q0, Q1, Q2, Q3, ... Q sprayed from the spraying means for mobile spraying and / or manual spraying at predetermined time intervals synchronized with the position information of the distributor 100. n Obtain the time t0, t1, t2, t3, ... t mentioned earlier. n The amount of bituminous material per unit time from a spraying means for mobile spraying and / or a spraying means for manual spraying in Q0, Q1, Q2, Q3, ...Q n This is obtained. Alternatively, the cumulative amount of bituminous material sprayed can be calculated by summing the amount of bituminous material sprayed per unit time obtained at predetermined time intervals.

[0042] If the area to be treated is a mobile spraying area, in other words, if the spraying mode is mobile spraying mode, then the amount of bituminous material sprayed per unit time (L / m²) is determined based on the amount of bituminous material sprayed per unit area (L / m²) acquired at predetermined time intervals. 2) may be calculated. The amount of bituminous material scattered per unit area at predetermined time intervals (L / m 2 ) L1, L2, L3, ...L n For example, the amount of bituminous material sprayed per unit time (L / s) Q0, Q1, Q2, Q3, ... Q n Distributor speed (m / s) V1, V2, V3, ...V n Based on the spray width (m)W of the spraying means for mobile spraying, it can be calculated using the following formula: L1 = Q1 / (W × V1) L2 = Q2 / (W × V2) ... L n =Q n / (W×V n ) However, the method for determining the amount of bituminous material to be sprayed per unit area at predetermined time intervals is not limited to the above calculation formula, and an appropriate method can be used depending on the accuracy of the information to be obtained. In addition, the distributor 100 may, if necessary, use a server described later to obtain the amount of bituminous material to be sprayed per unit area at predetermined time intervals. For example, the amount of bituminous material to be sprayed per unit area may be obtained by receiving the amount of bituminous material to be sprayed per unit area obtained by executing the above calculation formula on the server.

[0043] In the above formula, W represents the spray width of the bituminous material by the mobile spraying means. For example, a preset value may be used as the spray width W of the bituminous material, but in one preferred embodiment, the distributor 100 may be configured to have means for acquiring the spray width W of the bituminous material by the mobile spraying means. There are no particular restrictions on the specific method for acquiring the spray width W of the bituminous material by the mobile spraying means in the distributor 100, but for example, the operator of the distributor 100 may accept input of the spray width W on an input screen displayed on the touch panel of the control computer 109. In this case, the operator only needs to input the spray width W on the input screen displayed on the touch panel of the control computer 109 each time the spray width W is changed before or after the start of construction. Alternatively, the spray width of the mobile sprayer 101 may be calculated based on the open / closed state of the nozzle on / off valves corresponding to each spray nozzle of the mobile sprayer 101, the spacing between each spray nozzle, the spray width of each spray nozzle, etc.

[0044] On the other hand, if the area to be constructed is a manually sprayed area, in other words, if the spraying mode is manual spraying mode, the cumulative amount of bitumen material sprayed on the area to be constructed (L) may be determined based on the amount of bitumen material sprayed per unit time acquired at predetermined time intervals. The cumulative amount of bitumen material sprayed on the area to be constructed (L) is, for example, the amount of bitumen material sprayed per unit time from the spraying means for manual spraying acquired at predetermined time intervals Q0, Q1, Q2, Q3, ... Q n This can be calculated by accumulating the time over a predetermined period.

[0045] In one preferred embodiment, the amount of bituminous material applied per unit area in the manually applied section of the construction target area may be determined based on the cumulative amount (L) of bituminous material applied to the manually applied section of the construction target area. 2) is, for example, the total amount of bituminous material scattered in the construction area (L) and the area of ​​the construction area (m²). 2 It can be calculated based on ).

[0046] Area (m²) of the aforementioned construction target section which is a manually sprayed section 2 For example, a pre-set value may be used, but the construction area requiring manual spraying, i.e., hand sowing, can change depending on the site conditions, and it is difficult to know in advance the placement of obstacles, etc. Therefore, it is preferable that the distributor 100 be equipped with means for acquiring the area of ​​the area where bituminous material is sprayed by the manual spraying means, i.e., the area of ​​the manual spraying section. There are no particular restrictions on the specific method for acquiring the area of ​​the manual spraying section where bituminous material is sprayed by the manual spraying means in the distributor 100, but for example, the distributor 100 may be configured to accept input of the area of ​​the manual spraying section on an input screen displayed on the touch panel of the control computer 109 from the operator. In this case, the operator may, for example, select the manual spraying section as the construction area, switch the spraying mode to manual spraying mode, or after manual spraying is completed, input the area of ​​the manual spraying section on the input screen displayed on the touch panel of the control computer 109 each time.

[0047] Furthermore, the distributor 100 is equipped with an anemometer 111 as a means for measuring wind direction and wind speed. The anemometer that may be provided in a distributor according to one aspect of the present invention may be basically any type, as long as it can measure wind speed and / or wind direction at predetermined time intervals. The anemometer may be mounted at any position on the distributor, but it is preferable to mount it in a position where it is not obstructed by wind from the surroundings, for example, on the top of the vehicle of the distributor. Needless to say, it is also preferable that the wind speed and / or wind direction be measured at predetermined time intervals synchronized with the position information.

[0048] A distributor according to one aspect of the present invention includes means for transmitting the monitoring information of paving work acquired in the manner described above to a server on a network. In this example, the monitoring information acquired by the distributor 100 is transmitted to the server via the control computer 109. That is, in the distributor 100, the means for transmitting the monitoring information of paving work to a server on a network includes the control computer 109.

[0049] The monitoring information transmitted to the server may include virtually any information, as long as it relates to the construction management parameters of the paving work, and may include appropriate information as monitoring information according to the requests of the construction contractor, client, operator, etc. Examples of information included in the monitoring information include, but are not limited to, the construction date and time, temperature, type of bituminous material, temperature of the bituminous material, wind direction and / or wind speed at predetermined time intervals, and information regarding the spraying mode. For example, information regarding the design values ​​of construction management parameters may be included as monitoring information. Examples of information regarding the design values ​​of construction management parameters may include, but are not limited to, the type of bituminous material to be sprayed, the target amount of bituminous material to be sprayed per unit area, the target total amount of bituminous material to be sprayed, and the target temperature of the bituminous material.

[0050] If the section to be constructed is a mobile spraying section, in other words, if the spraying mode is a mobile spraying mode, the monitoring information preferably includes measured values ​​of the amount of bituminous material sprayed from the mobile spraying means at predetermined time intervals, and more preferably includes one or more of the following at predetermined time intervals: the position information of the distributor, the amount of bituminous material sprayed per unit area at predetermined time intervals, the cumulative amount of bituminous material sprayed at predetermined time intervals, and the speed of the distributor at predetermined time intervals.

[0051] If the construction target section is a manually sprayed section, in other words, if the spraying mode is manual spraying mode, the monitoring information preferably includes measured values ​​of the amount of bituminous material sprayed from the spraying means for manual spraying at predetermined time intervals, and more preferably includes one or more of the following at predetermined time intervals: the location information of the distributor and the cumulative amount of bituminous material sprayed at predetermined time intervals.

[0052] Furthermore, as described above, the monitoring information is preferably monitoring information at predetermined time intervals, and more preferably monitoring information at predetermined time intervals synchronized with the distributor's location information. In this case, it is preferable that the monitoring information is acquired and measured at predetermined time intervals, for example, at predetermined time intervals synchronized with the distributor's location information, and transmitted to the server. This makes it possible to check the monitoring information in real time via the server.

[0053] Furthermore, in one preferred embodiment, it is preferable that the monitoring information is transmitted to the server in association with construction identification information that identifies the construction work. The construction identification number that identifies the construction work can be basically any insofar as it can identify the construction work that the distributor 100 is targeting, but for example it may be a construction number, order number, ordering party, road name, construction date, or a combination thereof.

[0054] When monitoring information is transmitted to the server in association with construction identification information, the distributor 100 may be equipped with means for acquiring construction identification information to identify the construction. There are no particular restrictions on the means, but for example, the distributor 100 may be configured to acquire construction identification information by having the operator of the distributor 100 input construction identification information to identify the construction on an input screen displayed on the touch panel of the control computer 109. In this case, the distributor 100 transmits the monitoring information to the server in association with the construction identification information entered on the input screen displayed on the display screen of the control computer 109. The input screen displayed on the touch panel of the control computer 109 may be generated on the server. In this case, the input screen generated on the server is transmitted to the control computer 109 and displayed on the touch panel, which is the display unit of the control computer 109.

[0055] When transmitting monitoring information and construction identification information in association, it is not always necessary for the monitoring information and construction identification information to be transmitted simultaneously. For example, the distribution 100 may transmit the construction identification information to the server first, and then transmit the monitoring information. In this case, the server will associate the distribution 100 with the construction identification information, and then the monitoring information will be transmitted from the distribution 100 that has been associated with the construction identification information, making it possible to associate the transmitted monitoring information with the construction identification information.

[0056] Furthermore, in one preferred embodiment, it is preferable that monitoring information is transmitted to the server in association with section identification information that identifies the construction target section. The section identification information can be basically any information as long as it can identify one or more construction target sections included in the target construction, but for example, it may be the order in which the construction target sections were constructed, such as 1, 2, 3. When monitoring information is transmitted in association with section identification information, the server stores the section identification information and monitoring information in association. This makes it possible to manage monitoring information for each construction target section.

[0057] In one preferred embodiment, the monitoring information is preferably transmitted in association with distributor identification information that identifies the distributor. The distributor identification number that identifies the distributor can be basically anything insofar as it can identify the distributor, but for example, it may be a machine number assigned to an individual distributor.

[0058] When monitoring information is transmitted to the server in association with distributor identification information, the distributor may have means to obtain distributor identification information that identifies the distributor. There are no particular restrictions on the means, but for example, the distributor 100 may obtain the distributor identification information by having the operator of the distributor 100 input distributor identification information that identifies the distributor 100 on an input screen displayed on the touch panel of the control computer 109. In this case, the distributor 100 transmits the monitoring information to the server in association with the distributor identification number entered on the input screen displayed on the touch panel of the control computer 109. The input screen displayed on the touch panel of the control computer 109 may be generated on the server, transmitted to the control computer 109, and displayed on the touch panel, which is the display unit of the control computer 109.

[0059] When monitoring information is transmitted in association with project identification information and / or distributor identification information, the monitoring information for individual projects can be managed in association with the distributor identification information. For example, it becomes possible to centrally manage which distributor is in charge of which project, and / or was in charge of which project. Since the location information and project progress information of individual distributors can be checked as needed, distributor dispatchers, for example, can efficiently assign distributors to each scheduled project.

[0060] <Monitoring System> Next, a monitoring system for pavement construction including a distributor according to one aspect of the present invention will be described. Figure 2 is a conceptual diagram showing an example of a monitoring system for pavement construction including a distributor according to one aspect of the present invention. In Figure 2, 100A to C are distributors (hereinafter sometimes collectively referred to as "distributor 100"), 200 is a server, and 300A to C are terminal devices (hereinafter sometimes collectively referred to as "terminal device 300"). Server 200 can communicate with distributors 100A to C and terminal devices 300A to C via a network N including the internet.

[0061] <server> Server 200 is a cloud server distributed across the network and receives monitoring information transmitted from distributors 100A to C. When Server 200 receives monitoring information from each distributor, it stores the received monitoring information in cloud storage (not shown). In other words, Server 200 is equipped with means for receiving monitoring information from distributors and means for storing the received monitoring information in an appropriate storage unit (cloud storage in this example).

[0062] In this example, server 200 is a cloud server distributed across the network, but it does not necessarily have to be a cloud server; for example, it could be a single physical server device. Also, in this example, server 200 stores monitoring information in cloud storage distributed across the network, but the storage unit where the monitoring information is stored does not necessarily have to be cloud storage; for example, it could be a single physical storage device. Furthermore, if server 200 is a server device equipped with a storage unit such as an HDD or SSD, server 200 may store the monitoring information in that storage unit.

[0063] In one preferred embodiment, the server includes means for receiving project identification information and / or distributor identification information along with monitoring information from a distributor, and means for associating the received monitoring information with the project identification information and / or distributor identification information and storing it in an appropriate storage unit. This makes it possible to check the monitoring information for paving work for each project and / or for each distributor.

[0064] In one preferred embodiment, the server is provided with means for receiving paving work monitoring requests from terminal devices. Here, a paving work monitoring request may mean a request for the distribution of a monitoring screen for viewing the progress of the paving work.

[0065] In one preferred embodiment, the monitoring request for paving work transmitted from the terminal device is preferably a monitoring request that specifies a work. A monitoring request that specifies a work is not particularly limited as long as the work specified in the monitoring request can be identified, but for example, it may be a monitoring request that includes work identification information that identifies the work. The work identification information transmitted from terminal devices 300A~C and the work identification information transmitted from distributors 100A~C do not necessarily have to be the same, as long as the server can associate the two. For example, it is optional to use the client's order number as the work identification information transmitted from terminal devices 300A~C and the contractor's work number as the work identification information transmitted from distributors 100A~C. In such a case, the server may associate the two by referring to a storage unit or memory device that stores the work identification information transmitted from terminal devices 300A~C and the work identification information transmitted from distributors 100A~C in association with each other. Furthermore, if the project identification information transmitted from terminal devices 300A-C and the project identification information transmitted from the distributor are not identical, they do not necessarily have to correspond one-to-one. For example, multiple project numbers may be associated with a single order number. In this case, multiple projects may be designated simultaneously under a single order number.

[0066] When server 200 receives a monitoring request specifying a construction project from terminal devices 300A to C, it generates a monitoring screen that allows users to view the construction status of the specified project, and sends the generated monitoring screen to the terminal device that sent the monitoring request. The monitoring screen that allows users to view the construction status of the specified project may, for example, be a display screen that includes monitoring information for the specified project and / or information regarding the construction status based on the monitoring information for the specified project.

[0067] <Monitoring System Operation 1> Next, the operation of the monitoring system according to one aspect of the present invention will be explained with reference to the operations performed in the distributor 100 when paving work is carried out.

[0068] When performing paving work using the distributor 100, first, the operator of the distributor 100 or other authorized construction personnel starts the control computer 109 installed in the distributor 100 and displays the initial screen 400, for example, as shown in Figure 3, on the touch panel of the control computer 109.

[0069] As shown in the diagram, the initial screen 400 displays three menus: "Planning Data Input," "Start Measurement," and "End." When the operator selects "Planning Data Input" to begin construction work, the touch panel of the control computer 109 displays the planning data input screen 401, as shown in Figure 4. The operator simply needs to input the necessary information while looking at the planning data input screen 401.

[0070] Figure 5 shows the planning data input screen 402 after the operator has completed the input. In the measurement data input screen 402 shown in Figure 5, the following information is entered: "Construction number," "Construction name," "Construction location," "Client," "Type of work," "Emulsion type," "Vehicle number," and as design value information, the design value, upper limit, and lower limit of the "Emulsion spraying amount," as well as the design value of the spraying area.

[0071] In Figure 5, the vehicle number "DSB2024" is the machine number of distributor 100 and functions as distributor identification information. The distributor identification information only needs to be information that allows individual distributors to be identified by other distributors, and its format is arbitrary and not limited to that shown.

[0072] On the other hand, the construction number "12X345" in Figure 5 corresponds to the construction project entered into the planning data input screen 402, and is construction identification information that distinguishes the construction project to be carried out from other projects. The format of the construction identification information is arbitrary and not limited to that shown in the figure, as long as it can distinguish individual projects from other projects. If necessary, information other than the "construction number" may be used as construction identification information, such as "construction name," "construction location," "client," "type of work," "amount of emulsion sprayed," "vehicle number," or combinations thereof.

[0073] Furthermore, in the planning data input screen 402 shown in Figure 5, along with the type of asphalt emulsion to be sprayed (in Figure 5, "Asphalt Emulsion ABC"), information regarding its design value is provided, including the design value of the amount of asphalt emulsion to be sprayed per unit area (0.4 L / m²). 2 ) and the design value for the total spraying area (360m 2 The following values ​​have also been entered: Furthermore, the design values ​​for the amount of asphalt emulsion to be applied per unit area are the upper limit (5%) and lower limit (5%) permitted by internal standards, etc. In other words, for this project, the permissible range for the amount of asphalt emulsion to be applied per unit area is 0.38 L / m². 2 ~0.42 L / m 2 That is the case.

[0074] On the planning data input screen 402, once the necessary information has been entered, the operator clicks the "Save Settings" button displayed in the lower left corner of the planning data input screen 402 to store the entered planning data in the memory unit of the control computer 109, or in a suitable storage device accessible to the control computer 109. This operation returns the display screen on the touch panel of the control computer 109 to the initial screen 400 shown in Figure 3. Incidentally, the "Load Settings" button displayed in the lower left corner of the planning data input screen shown in Figures 4 and 5 is used to load planning data stored in the memory unit of the control computer 109, or in a suitable storage device accessible to the control computer.

[0075] Next, when the operator clicks "Start Measurement" on the initial screen shown in Figure 3, the control computer 109 sends the construction plan data, which was entered on the plan data input screen earlier and stored in the control computer's memory or an appropriate storage device accessible by the control computer, to the server 200. The construction plan data is usually the most recently saved construction plan data in the control computer, but it is also possible to allow the operator to select from already saved plan data on the control computer 109's screen before clicking "Start Measurement".

[0076] In this example, the planning data transmitted from the control computer 109 to the server 200 includes design value information such as the type of asphalt emulsion, the amount of asphalt emulsion to be sprayed, and the spraying area, which are construction management parameters, along with construction identification information. This design value information for construction management parameters, along with the location information of the distributor at predetermined time intervals, and the measured values ​​of the amount of bituminous material sprayed from the spraying means for mobile or manual spraying at predetermined time intervals synchronized with the location information, constitutes monitoring information for the construction project.

[0077] When "Start Measurement" is clicked on the initial screen shown in Figure 3, the control computer 109's touch panel displays the monitoring screen 403 as shown in Figure 6. As shown in Figure 6, the monitoring screen 403 displays the current values ​​for "Spraying Mode," "Nozzle Open / Close Status," "Spraying Width," "Emulsion Temperature," "Emulsion Specific Gravity," "Travel Speed," "Current Spraying Amount," "Cumulative Spraying Amount," "Temperature," "Humidity," "Wind Speed ​​and Direction," and "Elapsed Time." In this example, the "Travel Speed" column, which represents the speed of the distributor 100, shows "0.0 km / h," and the "Current Spraying Amount" column, which represents the amount of bituminous material sprayed per unit area, shows "0.00 L / m." 2In the "Total Amount Spread" column, which represents the total amount of bituminous material spread, "0.0L" is displayed, and in the "Elapsed Time" column, which represents the elapsed time since the start of spraying, "0:00:00" is displayed. These values ​​correspond to the fact that in this example, distributor 100 has not yet started spraying the bituminous material. On the other hand, in the "Emulsion Temperature" column, which represents the temperature of the bituminous material (asphalt emulsion in this example), "65.87℃" is displayed, showing the temperature of the asphalt emulsion in the insulated tank measured by the temperature sensor in the insulated tank. In addition, in the "Nozzle Open / Close Status" column, the open / close status of the spray nozzles equipped on the spray bar for mobile spraying is displayed using the symbols "●" (closed) and "〇" (open), and the spray width of "2.00m" in this state is displayed. By clicking the "Change Spray Width" button, the open / close status of the spray nozzles and the spray width can be changed. Furthermore, the "Wind Speed / Direction" column displays "2.0 m / s, Wind Direction: East-Northeast," showing the wind speed and direction measured by the anemometer. From these values, the operator of Distributor 100 can understand that the conditions are met to begin spraying the bituminous material.

[0078] In one preferred embodiment, the system may be configured to alert the operator if the wind speed measured by the anemometer exceeds a predetermined value. For example, the color of the wind speed display field on the measurement screen displayed on the touch panel of the control computer 109 may be changed, or a warning sound may be emitted. Multiple predetermined values ​​may be set, and in this case, different warning methods may be used in stages depending on the magnitude of the predetermined value. Thus, in one preferred embodiment, the distributor according to one aspect of the present invention may be equipped with a warning means that alerts the operator when the wind speed exceeds a predetermined value. Since the bituminous material is scattered from the distributor as fine particles, there is a possibility that the bituminous material may be scattered into the surroundings depending on the wind speed and wind direction. When the distributor according to one aspect of the present invention is equipped with the above configuration, the risk of scattering of the bituminous material can be detected quickly.

[0079] Furthermore, the monitoring screen 403 displays a "Spray Mode Switching" button, and clicking this button allows you to switch the spray mode. In this example, as indicated by "Moving Spray Mode" in the "Spray Mode" field, "Moving Spray Mode" is selected. In other words, the type of section to be treated is a moving spray section.

[0080] In this state, clicking the "Start Measurement" button in the lower left of the monitoring screen 403 causes the distributor 100 to begin acquiring measurement data from various measuring instruments and to begin transmitting the acquired data to the server. Specifically, the control computer 109 uses the reception time of the earliest received positioning signal from the time "Start Measurement" is clicked on the monitoring screen 403 as the start time t0, and acquires the latitude and longitude information of the distributor 100 at predetermined time intervals from there, and begins transmitting this as position information to the server 200. At the same time, the control computer 109 acquires various measurement values ​​from other measuring instruments connected to the distributor 100 at a timing synchronized with the location information of the distributor 100, and transmits them to the server 200 in association with the acquisition time of the aforementioned position information.

[0081] Measurements from other connected measuring instruments include, for example, the flow rate of bituminous material per unit time (L / s) measured by the flow meter 104, the speed of the distributor 100 (km / h) determined based on the position information of the distributor 100 at predetermined time intervals or measured by the speedometer, and the amount of bituminous material sprayed per unit area (L / m) from the spraying means for mobile spraying. 2 The monitoring information may include one or more of the following: the cumulative amount of bituminous material sprayed (L), the temperature of the bituminous material (°C), the remaining amount of bituminous material in the insulated tank, wind direction, wind speed (km / h), the type of section to be constructed, the spraying mode, and construction area identification information to identify the construction area. Of this monitoring information, those that can be calculated by the server 200 may be configured to be calculated by the server 200.

[0082] Figure 7 shows an example of a monitoring screen displayed during mobile spraying. In the monitoring screen 404 shown in Figure 7, the "Driving Speed" column displays "27.8 km / h," and the "Current Spraying Amount" column displays "0.42 L / m." 2 The "Cumulative Spray Amount" column displays "129.4L," and the "Elapsed Time" column displays "0:00:20," showing the latest monitoring information acquired at predetermined time intervals, allowing the operator of Distributor 100 to check the application status in real time.

[0083] In one preferred embodiment, if the area to be constructed is a mobile spraying area, the system may be configured to alert the operator if the amount of bituminous material sprayed per unit area, obtained at predetermined time intervals, is not within a predetermined range. As mentioned above, in this example, the design value for the amount of asphalt emulsion sprayed per unit area is "0.4 L / m 2 Regarding the amount of asphalt emulsion sprayed per unit area, the company's internal standards allow an upper limit of "+5%" and a lower limit of "-5%", therefore the permissible range for the amount of asphalt emulsion sprayed per unit area is "0.38 L / m²". 2 ~0.42 L / m 2 In other words, the distributor 100 distributes the bituminous material per unit area within the above range (0.38 L / m²) at predetermined time intervals. 2 ~0.42 L / m 2 The system may be configured to determine whether or not the amount of bituminous material sprayed per unit area is within the above range, and if it is determined that the amount of bituminous material sprayed per unit area is not within the above range, a warning signal may be issued to alert the operator. In the monitoring screen 404 shown in Figure 7, the amount of bituminous material sprayed per unit area is shown in the "Current spraying amount" column as "0.42 L / m 2。 English: Since this amount of spraying is within the above range, the distributor 100 does not emit a warning signal. On the other hand, if the amount of bituminous material sprayed per unit area deviates from the above range due to changes in the speed of the distributor 100, the distributor emits a warning signal to alert the operator. There are no particular restrictions on the specific form of the warning signal, but since the warning is issued while the operator is driving, it is preferable that it be an audio signal that can be easily recognized even while driving. For example, if the amount of bituminous material sprayed per unit area at predetermined time intervals is less than the above range, the distributor may emit an audio guidance saying, "Less than the design spraying amount. Slow down the speed." If it is greater than the above range, it may emit an audio guidance saying, "Exceeding the design spraying amount. Speed ​​up the speed."

[0084] Note that monitoring screen 404 is merely one example of a monitoring screen displayed during mobile spraying; other information may be included or the display method may be changed as needed.

[0085] Figure 8 shows another example of a monitoring screen displayed during mobile spraying. In addition to the monitoring screen 404 shown in Figure 7, the monitoring screen 405 in Figure 8 also displays the elapsed time from the start of measurement (t0) and the amount of asphalt emulsion sprayed per unit area (L / m²). 2 A graph showing the correspondence between the two is displayed. Thus, in one preferred embodiment, the monitoring screen displayed during mobile spraying may be a display screen that includes a correspondence between the distance traveled by the distributor from an arbitrary origin or the elapsed time from an arbitrary disclosure time, which is determined based on the distributor's position information measured at predetermined time intervals, and the amount of bituminous material sprayed per unit area and / or the amount of bituminous material sprayed.

[0086] Meanwhile, the server 200, which receives monitoring information from the control computer 109, stores the received monitoring information in cloud storage, associating it with the distributor identification information of the distributor that sent the monitoring information and the construction identification information of the construction project that the distributor is working on. If necessary, it may also store the information as associated with section identification information that identifies the sections to be constructed, such as lane 1, lane 2, lane 3, etc.

[0087] Once the application of asphalt emulsion to the designated construction area is complete, the operator should click the "Stop Measurement" button on the monitoring screen. This will interrupt the acquisition of various measurement data that make up the monitoring information, and the transmission of monitoring information to the server 200. However, the acquisition of measurement data by various measuring instruments may be continued.

[0088] By clicking the "Next Lane" button, the construction target section switches to the next section, and the monitoring screen 403 shown in Figure 6 is displayed again. If the next construction target section is, for example, a manual spraying section where asphalt emulsion needs to be sprayed manually, to switch the spraying mode, click the "Spraying Mode Switching" button on the displayed monitoring screen and select manual spraying mode on the displayed screen (not shown). When manual spraying mode is selected as the spraying mode, that is, when a manual spraying section is selected as the type of construction target section, for example, the manual spraying monitoring screen 406 shown in Figure 9 is displayed. In the manual spraying monitoring screen 406 shown in Figure 9, "Manual Spraying" is displayed in the "Spraying Mode" field. This indicates that manual spraying mode is selected as the spraying mode, in other words, this construction target section is a manual spraying section. Furthermore, the monitoring screen 406 for manual spraying shown in Figure 9 is provided with a data input field for the "spraying area" of the manual spraying section where asphalt emulsion is manually sprayed. The operator simply needs to input the necessary information (area of ​​the manual spraying section) here.

[0089] After entering the spraying area, clicking the "Start Measurement" button causes the distributor 100 to begin acquiring data from various measuring instruments and to begin sending monitoring information, including the acquired data, to the server. The operator simply needs to use the manual spray bar attached to the distributor 100 to spray the asphalt emulsion over the designated area. Figure 10 shows an example of the monitoring screen during manual spraying, specifically the monitoring screen 407. The monitoring screen shown in Figure 10 displays monitoring information including the "elapsed time" since the start of spraying and the "cumulative amount of asphalt emulsion sprayed." Once the manual spraying is complete, the operator should click the "Stop Measurement" button on the monitoring screen 407. This will end the transmission of various measurement data to the server 200.

[0090] Once all work is complete, the operator simply clicks the "End Measurement" button displayed in the lower right corner of the monitoring screen.

[0091] In the above explanation, the control computer 109 is operated by an operator, but it goes without saying that it may also be operated by a site supervisor or other authorized construction personnel. Furthermore, instead of the control computer 109, the above operations may be performed on a terminal device owned by, for example, a site supervisor or other authorized construction personnel.

[0092] <Monitoring System Operation 2> Next, we will explain how the operation of terminal devices 300A-C (hereinafter sometimes simply referred to as "terminal device 300") can be used by the client or other parties involved in the construction to monitor the progress of the paving work. Note that terminal devices 300A-C may be, but are not limited to, personal computer terminals, smartphone terminals, or tablet terminals.

[0093] When the client or construction personnel access the site provided by the server 200 of the monitoring system in this example from the terminal device 300, a login screen 408, such as the one shown in Figure 11, is displayed on the display units of the terminal devices 300A to C.

[0094] The login screen 408 shown in Figure 11 has input fields for the project number and the password. When the client or project personnel enter the project number of the project they wish to monitor and the corresponding password on this login screen and click the "Login" button, the project number and the corresponding password are sent to the server 200. In this way, the terminal device 300 sends a monitoring request specifying the project to the server 200. In other words, in this example, the project that is the target of the monitoring request is specified by the project number. The server 200 receives the monitoring request from the terminal device 300, generates a monitoring screen that allows viewing of monitoring information for the project identified by the project number included in the received monitoring request, and sends it to the terminal device 300. The terminal device 300 receives this, and the generated monitoring screen is displayed on the terminal device 300's display screen.

[0095] In this example, the combination of the project identification number, which identifies the project, and the password assigned to the project in question functions as authentication information for viewing the monitoring information of that project. Specifically, the server 200 determines whether the combination of project identification information and password received from the terminal device 300 matches any previously stored combinations of project identification information and password. If it determines that they match, the server 200 authenticates the terminal device 300 as belonging to a person authorized to monitor the project identified by the project identification information, and transmits a display screen to the terminal device that allows it to view the monitoring information.

[0096] However, the above authentication method is merely an example, and other authentication information besides the combination of project identification information and password may be used as authentication information. For example, a combination of user identification information, such as a user number, and a password; a combination of project identification information, such as a project order number, and a password; or a combination of a distributor identification number and a password may be used as authentication information.

[0097] Authentication information can be provided to the user in advance, for example, by sending it from the server 200 to the registered user's terminal device beforehand. The authentication information may also be provided to the user in the form of a two-dimensional code such as a barcode or a three-dimensional code such as a QR code (registered trademark).

[0098] Figure 12 shows an example of a monitoring screen displayed on the display screen of the terminal device 300. The monitoring screen 409 shown in Figure 12 is a monitoring screen that allows users to view monitoring information for each construction target section for the construction project specified by the construction number entered on the login screen 408.

[0099] The monitoring screen 409 shown in Figure 12 displays a map showing a total of five construction target sections included in the specified construction project. On the map, rectangular bands represent individual construction target sections, with sections filled in with a dotted pattern indicating unconstructed sections and sections filled in black indicating completed sections. Arrows on the map indicate the construction target section selected for viewing. The monitoring screen 409 is configured so that the user of the terminal device 300 can select the construction target section for which they want to view monitoring information from the displayed sections. In this example, lane 2, which is currently under construction, is selected as the construction target section. To check the construction status of other lanes, simply click on the other lane on the map.

[0100] Meanwhile, on the map, the location indicated by a callout containing the distributor's machine number shows the distributor's current location. During construction, the server 200 acquires monitoring information, including location information, from the distributor 100 at predetermined time intervals and records it in cloud storage. Accordingly, the distributor's location, the display of unconstructed sections, and the display of completed sections on the diagram are gradually updated, allowing the user of the terminal device 300 to grasp the progress of the construction in real time and intuitively via the monitoring screen 409.

[0101] In the upper title field of the monitoring screen shown in Figure 12, the "Project Name," "Construction Location," "Date," and "Time" are displayed. Below that, on the right, a project information field is displayed, showing some project identification information such as "Contractor," "Type of Work," and "Vehicle," as well as design values ​​for construction management parameters such as "Design Emulsion Application Rate." This information constitutes part of the monitoring information transmitted from the control computer 109 installed in the distributor 100 to the server 200. The server 200 stores this information in cloud storage, associating it with distributor identification information that identifies the distributor who sent the monitoring information and project identification information that identifies the project targeted by that distributor. The server 200 can read information already stored in cloud storage and information stored over time as needed and use it to generate the monitoring screen.

[0102] Furthermore, the lower part of the monitoring screen 409 shown in Figure 12 displays the amount of asphalt emulsion sprayed per unit time (L / m²) by the distributor, starting from the start time of construction (t0). 2 A graph showing the time-dependent changes in the cumulative amount of splatter (L) is displayed. Also, to the right of each graph, the current time (t n The amount of asphalt emulsion sprayed per unit time (L / m²) 2The measured values ​​of the amount of asphalt emulsion (L / m³) and the cumulative amount of asphalt emulsion (L / m³) are displayed. In the example shown, the elapsed time from the start time of the construction (t0) is plotted on the horizontal axis to show the change in each measured value over time as a graph, but the method of displaying each measured value is not limited to this. For example, as shown in the monitoring screen 410 in Figure 13, the distance traveled by the distributor from the start point of the construction (m) is plotted on the horizontal axis, and the amount of asphalt emulsion (L / m³) per unit time that changes with the distance traveled is also displayed. 2 ) and the measured value of the cumulative amount of sprayed (L) may also be displayed. In any case, the monitoring screen 409 displays the measured values ​​of the construction management parameters plotted in correspondence with the distance traveled from the starting point of the construction and / or the elapsed time since the start of the construction, so that the client or construction personnel can monitor the progress of the construction in real time with a sense of presence, even from a location far from the site.

[0103] The monitoring screen may include other information as needed. For example, it may display the construction area and the type of spraying mode, or it may display indicators of the design values ​​of construction management parameters on the graph of the asphalt emulsion spraying amount. As an indicator of the design values ​​of construction management parameters, for example, a baseline indicator of the design value may be displayed on the vertical axis of the graph of the asphalt emulsion spraying amount at a position corresponding to the design value of the construction management parameter, or tolerance lines indicating the tolerance may be displayed on the vertical axis at positions corresponding to the upper and lower tolerance limits of the deviation from the design value. By displaying information that indicates the design values ​​of construction management parameters in this way, the client or construction personnel can intuitively grasp the degree of agreement between the measured values ​​and the design values, and the degree of deviation between the measured values ​​and the design values. Needless to say, the monitoring screen including these displays may also be displayed on the display unit (touch panel) of the control computer of the distributor 100, which can be viewed by the operator.

[0104] On the other hand, Figure 14 shows an example of the monitoring screen when lane 1, which is a construction target section (manually sprayed section) that has already been constructed by manual spraying, is selected. The display contents of monitoring screen 411 shown in Figure 14 are basically the same as monitoring screen 409, but instead of displaying the amount of asphalt emulsion sprayed per unit area and the cumulative amount of asphalt emulsion sprayed, which are plotted in relation to the distance traveled from the origin of the construction start and / or the elapsed time since the start of construction, the amount of asphalt emulsion sprayed per unit area, the cumulative amount of asphalt emulsion sprayed, and the sprayed area for the entire lane 1 are displayed.

[0105] It goes without saying that the monitoring screen, which allows users to view monitoring information for manually sprayed sections, may also include other information as needed. Furthermore, the display method is not limited to that exemplified in monitoring screen 411; it may be presented in a way that is easy to understand visually, such as by graphing, as needed. [Industrial applicability]

[0106] As described above, according to one aspect of the present invention, the distributor and / or monitoring system makes it possible to monitor the progress of asphalt emulsion application in real time, even in applications where manual application by hand and application by a distributor are mixed. By making the progress of the paving work visible to all those involved in the paving work, including the person in charge of the paving work, the supervisor, and the client, it becomes possible to perform higher quality paving work, more detailed maintenance, and better quality assurance of the pavement.
