On the other hand, one of the important issues in livestock farming is odor control (see Non-Patent Document 1). [Prior art documents] [Non-patent literature]

Summary of the Invention [Problem to be solved by the invention]

[0004] Due to the proximity of livestock farms to residential areas and the growing public awareness of environmental issues, complaints about odors at livestock farms are becoming more serious. Odor complaints from residents can make it difficult for a farm to continue operating, or the cost of dealing with complaints can put the farm under strain. Therefore, odor control is necessary as a management issue for livestock farms and a lifestyle issue for residents. In some cities and towns in Japan, tripartite councils consisting of producers, residents, and the government have been established, and efforts are being made to solve the problem. In response to this situation, a technical approach is needed to reduce the odors that spread around livestock farms in order to ensure the survival of livestock farms and the comfortable lives of local residents.

[0005] The disclosed technology has been developed in consideration of the above points, and aims to provide an odor improvement system, an odor improvement device, and an odor improvement program that can efficiently improve odors around a facility. [Means for solving the problem]

[0006] The first aspect of the present disclosure is an odor improvement system, which includes a spray device for spraying an effective agent for improving an odorous environment outside a facility, and a control device for controlling the execution of spraying the effective agent by the spray device, and the spray device is composed of at least a pump for storing the effective agent, and a nozzle installed so that the effective agent stored in the pump can be sprayed outside the facility. This makes it possible to efficiently improve the odor around the facility.

[0007] In addition, the odor improvement system may include a control device that includes a receiving unit that receives data related to spray conditions, a setting unit that sets spray conditions according to the conditions related to the data, and a control unit that uses the received data as input parameters and executes spraying of the efficacy agent outside the facility so as to satisfy the spray conditions. This makes it possible to control spraying according to conditions.

[0008] In addition, for the odor improvement system, the data may include at least one of observed weather data and work data related to work performed in the facility, and the conditions related to the data may include at least one of weather conditions related to the weather data and work conditions related to the work data. This makes it possible to control spraying according to the weather data and work data that change from time to time.

[0009] In addition, for the odor improvement system, the reception unit may further receive analysis data simulating the diffusion situation using at least one of the location conditions and weather forecasts related to the facility, and the setting unit may set the spray conditions according to the analysis data, the weather conditions, and the work conditions. This makes it possible to set spray conditions that enable more efficient spraying in terms of both odor improvement effect and cost, using analysis data that accurately estimates how much diffusion will occur around the facility.

[0010] In addition, in the odor improvement system, the setting unit can set a criterion that combines a plurality of conditions based on the analysis data, the weather conditions, and the work conditions as the judging criteria for the spray conditions, and set, as the implementation requirements for the spray conditions, the length of the required spray time according to at least one of the work type and the work time that are predetermined as the work conditions, and the spray stop time according to the stop time period that is predetermined as the work conditions. This makes it possible to perform precise spray control.

[0011] In addition, in the odor improvement system, the nozzle may be configured to include a plurality of nozzles, the setting unit may determine the amount of spray required according to the work conditions as the spray conditions, and the control unit may control the amount of spray by selecting the number of the nozzles that perform spraying. This allows the amount of spray to be controlled.

[0012] In addition, the odor improvement system may be configured such that the nozzle is composed of a plurality of nozzles with different opening sizes, the setting unit determines the necessary amount of spray according to the work conditions as the spray conditions, and the control unit controls the amount of spray by selecting the nozzle that will perform spraying according to the nozzle opening size and the necessary amount of spray. This makes it possible to control the amount of spray.

[0013] A second aspect of the present disclosure is an odor improvement device that includes a receiving unit that receives data related to spray conditions, a setting unit that sets the spray conditions according to the conditions related to the data, and a control unit that uses the received data as input parameters and executes spraying of an effective agent for improving an odorous environment outside a facility so as to satisfy the spray conditions. This makes it possible to control spraying according to weather data and work data that change from time to time.

[0014] In addition, for the odor improvement device, the data may include at least one of observed weather data and work data related to work to be performed in the facility, and the conditions related to the data may include at least one of weather conditions related to the weather data and work conditions related to the work data. This makes it possible to control spraying according to the weather data and work data that change from time to time.

[0015] In addition, for the odor improvement device, the reception unit may further receive analysis data that simulates the diffusion situation using at least one of the location conditions and weather conditions related to the facility, and the setting unit may set the spray conditions according to the analysis data, the weather conditions, and the work conditions. This makes it possible to set spray conditions that enable efficient spraying in terms of both odor improvement effect and cost, using analysis data that accurately estimates how much diffusion will occur around the facility.

[0016] A third aspect of the present disclosure is an odor improvement program that causes a computer to execute a process of receiving data related to spray conditions, setting spray conditions according to the conditions related to the data, and using the received data as input parameters to execute spraying of an effective agent for improving an odorous environment outside a facility so as to satisfy the spray conditions. This allows the spraying to be controlled according to weather data and work data that change from time to time.

[0017] In addition, in the odor improvement program, the data may include at least one of observed weather data and work data related to work performed in the facility, and the conditions related to the data may include at least one of weather conditions related to the weather data and work conditions related to the work data. This makes it possible to control spraying according to the weather data and work data that change from time to time.

[0018] The odor improvement program can also receive analysis data that simulates the diffusion situation using at least one of the location conditions and weather conditions related to the facility, and set the spray conditions according to the analysis data, the weather conditions, and the work conditions. This makes it possible to set spray conditions that enable efficient spraying in terms of both odor improvement effect and cost, using analysis data that accurately estimates how much the odor will diffuse around the facility.

[0019] According to the disclosed technology, odors around a facility can be efficiently improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, an example of an embodiment of the disclosed technology will be described with reference to the drawings. In each drawing, the same or equivalent components and parts are given the same reference numerals. In addition, the dimensional ratios of the drawings are exaggerated for the convenience of explanation and may differ from the actual ratios.

[0022] First, an overview of the present disclosure will be described. The odor improvement system according to the technology of the present disclosure aims to reduce odors around the facility. This technology is applicable not only to livestock farms but also to facilities that generate some kind of odor, and may be applied to other agricultural facilities and industrial facilities, for example. Conventionally, it was assumed that the agent would be sprayed inside the facility (see Non-Patent Document 1), but the feature of this technology is that the odor around the facility is reduced by spraying an effective agent that improves the odor environment outside the facility. As the effective agent, a masking agent (aromatic deodorizer), a deodorizer, a disinfectant, an odor control agent, and other agents that can improve the odor environment can be appropriately used. In Non-Patent Document 1, the odor improvement effect of a spray-type aromatic deodorizer has been confirmed, and the results of the "6-level odor intensity indication method" and the "9-level pleasantness / unpleasantness indication method" for the inside of the compost building and the downwind site boundary are shown.

[0023] FIG. 1 is an image diagram comparing the case where the efficacious agent is sprayed inside the facility by the conventional method with the case where the efficacious agent is sprayed outside the facility by the present method. In the example of FIG. 1, the efficacious agent can only be sprayed in a limited range indoors by the conventional method. On the other hand, when spraying outside the facility as in the present method, a nozzle 144 is installed on the roof of the facility and the outer wall surrounding the facility, and the efficacious agent is sprayed from the nozzle 144 to the outside. In this case, the efficacious agent is diffused around the facility by the outside wind, so odor improvement can be expected in a wider range around the facility than by spraying the efficacious agent in a limited range indoors. In this way, the odor improvement system of this embodiment efficiently improves odor by spraying the efficacious agent outside the facility while taking into account weather conditions, etc. In addition, since purchasing the efficacious agent requires cost, if the amount of the efficacious agent can be reduced, it can also contribute to reducing the cost of facility management.

[0024] (Configuration of odor improvement system) The configuration of this embodiment will be described below.

[0025] Fig. 2 is a diagram showing an example of the configuration of an odor improvement system. As shown in Fig. 2, in the odor improvement system 100, a control device 110, a meteorological observation device 120, a simulation environment 130, and a spray device 140 are connected via a network N.

[0026] The control device 110 controls the execution of spraying of the efficacy agent by the spray device 140. The control device 110 includes a receiving unit 112, a setting unit 114, and a control unit 116. The control device 110 is an example of an odor improving device of the technology of the present disclosure.

[0027] The weather observation device 120 is a device capable of observing the weather (whether it is raining, the amount of rain, etc.), wind direction, and wind speed around the facility. Instead of the weather observation device 120, an external weather information service that monitors the weather conditions around the facility may be used.

[0028] The simulation environment 130 is an environment for calculating analysis data obtained by simulating the diffusion state using the location conditions and weather forecast related to the facility by CFD (Computational Fluid Dynamics) or the like. For example, an environment in which analysis software can be executed in a cloud environment or the like is prepared, and the location conditions and weather forecast related to the facility are input into the analysis software for calculation, and the analysis data is output. The location conditions may be general map data including a predetermined range around the facility and an altitude. The weather forecast may be obtained from an external weather forecast service or from the weather observation device 120. FIG. 3 is a diagram showing an example of a simulation result of analysis data for each location. As shown in FIG. 3, it can be seen that the simulation results show different degrees of diffusion concentration depending on the location and altitude. In (a), the altitude is low at 26 m, and the diffusion concentration is high because it accumulates in a certain range, but on the other hand, it can be seen that the altitude is high in (b), (c), and (d), and the diffusion is widespread. It is assumed that diffusion over a wider range will be more effective in improving odors. By performing a simulation using the location conditions and weather forecast, it is possible to obtain analytical data that accurately estimates how much of the functional agent will spread around the facility when sprayed at the facility's location. Furthermore, a simulation may be performed using at least one of the location conditions and weather forecast. By using such analytical data, it is possible to easily understand how long it takes to spray the functional agent to achieve odor improvement effects. If an operator arbitrarily determines spray conditions without using analytical data, the spraying will be performed according to the operator's assumptions. On the other hand, by using analytical data from the simulation results, it is possible to set spray conditions that allow more efficient spraying in terms of both odor improvement effects and costs.

[0029] The spray device 140 is a device for spraying a functional agent for improving an odorous environment outside the facility. The spray device 140 includes a pump 142 and a plurality of nozzles 144. The functional agent is stored in the pump 142. The pump 142 is provided with a microcomputer or the like, and may have a mechanism for ejecting the functional agent to the nozzle 144 in response to an instruction from the control device 110 (not shown). The nozzle 144 is installed at a predetermined position in the facility so that the functional agent stored in the pump 142 can be sprayed outside the facility. The nozzle 144 may be installed at any position where the nozzle 144 can open so that the functional agent can be sprayed outside the facility, such as the rooftop of the facility or the outer wall surrounding the facility. The nozzle 144 may also be installed outside the facility (near the facility). Spraying by the spray device 140 can be performed by sucking up the functional agent from the pump 142 and ejecting it from the opening of the nozzle 144 outside the facility. Hoses (not shown) connecting the pump 142 and the nozzle 144 may be used as necessary.

[0030] (Hardware configuration of the control device 110) 4 is a block diagram showing a hardware configuration of the control device 110. As a hardware computer, for example, a Raspberry Pi can be used, which can be realized at low cost.

[0031] 4, the control device 110 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a storage 14, an input unit 15, a display unit 16, and a communication interface (I / F) 17. Each component is connected to each other via a bus 19 so as to be able to communicate with each other.

[0032] The CPU 11 is a central processing unit, and executes various programs and controls each part. That is, the CPU 11 reads a program from the ROM 12 or the storage 14, and executes the program using the RAM 13 as a working area. The CPU 11 controls each of the above components and performs various arithmetic processing according to the program stored in the ROM 12 or the storage 14. In this embodiment, a control program is stored in the ROM 12 or the storage 14.

[0033] The ROM 12 stores various programs and various data. The RAM 13 temporarily stores programs or data as a working area. The storage 14 is configured with a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and stores various programs including an operating system, and various data.

[0034] The input unit 15 includes a pointing device such as a mouse, and a keyboard, and is used to perform various input operations.

[0035] The display unit 16 is, for example, a liquid crystal display, and displays various information. The display unit 16 may function as the input unit 15 by adopting a touch panel system.

[0036] The communication interface 17 is an interface for communicating with other devices such as terminals. For this communication, for example, a wired communication standard such as Ethernet (registered trademark) or FDDI, or a wireless communication standard such as 4G, 5G, or Wi-Fi (registered trademark) is used. This concludes the description of the hardware configuration of the control device 110.

[0037] Next, a description will be given of each functional configuration of the control device 110. Each functional configuration is realized by the CPU 11 reading out a control program stored in the ROM 12 or the storage 14, expanding it in the RAM 13, and executing it.

[0038] The reception unit 112 receives weather data, work data, and analysis data as inputs at an appropriate timing. The weather data is meteorological information including weather, wind direction, and wind speed observed by the weather observation device 120. The work data is data related to work performed at the facility input by the worker from the input unit 15 or the like. For example, the work type and work time are received as the work data. The analysis data is a simulation result for the facility analyzed in the simulation environment 130. The weather data and work data are used as input parameters for condition determination by the control unit 116. The analysis data is used for setting the spray conditions of the setting unit 114. Note that, although the manner of receiving the weather data and work data as input parameters will be described below, this is not limiting. For example, at least one of the weather data and the work data, or data related to other spray conditions, may be received as input parameters. As data related to other spray conditions, events at the facility or around the facility may be used. By using the event data, it is possible to adjust the presence or absence of spray during the event, the spray time, and the like.

[0039] The setting unit 114 sets the spray conditions according to the analysis data, weather conditions, and work conditions. Here, the spray conditions can be determined by dividing them into a judgment criterion and an implementation requirement. The judgment criterion is a criterion for determining whether or not to perform spraying for each time period. The implementation requirement is various settings for performing spraying. The various settings are settings such as the time period for spraying, which nozzle 144 is used for spraying, and in what weather data the spraying is stopped when the weather data is updated. The weather conditions and work conditions are conditions that are the basis for setting the judgment criterion and the implementation requirement (examples are described below). The weather conditions and work conditions may be determined in advance, may be input by the worker, and may be changed as appropriate.

[0040] The judgment criteria can be determined by appropriately selecting a plurality of conditions that allow spraying from the analysis data, weather conditions, and work conditions, and combining the conditions. For example, a condition that the planned work is a specific work type may be set as a work condition. The conditions used in the combination will be described. A condition based on the analysis data that allows spraying to be performed when the analysis data is dispersed over a relatively wide range toward the direction of the surrounding facilities due to the location of the facility may be used. A weather condition that allows spraying to be performed when the wind direction in the weather data is toward the surrounding facilities and the wind speed is equal to or higher than a certain speed may be used. A weather condition that allows spraying to be performed when the weather in the weather data is other than rain may be used. A work condition that allows spraying to be performed when the work type scheduled in the work data is expected to have a large amount of odor (the level of odor amount is set in advance for the work type) may be used. In addition to the above, other conditions that can be set from a combination of the analysis data, weather conditions, and work conditions may be determined. In addition, a stepwise determination criterion may be used in which a determination is made as to whether or not to spray depending on the type of work as a first determination criterion, and a criterion combining the above conditions is set as a second determination criterion, and a determination is made according to the second determination criterion when the first determination criterion is satisfied. As described above, in the setting unit 114, the determination criterion for the spray condition may be set by appropriately combining these conditions. The setting may be automatic, or the operator may set the criterion based on an automatically generated determination criterion. When the operator sets the criterion, the display unit 16 may display a simulation result of the analysis data, for example.

[0041] The implementation requirements can be set and adjusted according to the analysis data, weather conditions, and work conditions. For example, as work conditions, the length of the required spray time is set according to the work type and work time of the scheduled work data. If the work time of a certain work type (e.g., turning compost) is one hour, the spray time is set according to the required amount of sprayed functional agent, such as one hour of spraying or two hours of spraying based on the start point of the work. The spray time may also be determined from at least one of the work type and work time. The spray amount can be adjusted according to the spray time. In addition, since the degree of diffusion differs depending on the location conditions and weather forecast data even in the analysis data, the spray time may be adjusted according to the degree of diffusion. For example, the spray time may be shortened when the degree of diffusion is wide, and lengthened when the degree of diffusion is narrow. In addition, adjustments may be made according to the wind direction and wind speed of the observed weather data without using the analysis data. This allows the functional agent to be sprayed in the required amount, thereby realizing cost savings.

[0042] In addition, the implementation requirements are set with a priority in consideration of the case where the spray time and the stop time zone overlap. For example, if the stop time zone is set as a work condition such that the spray is stopped from 9 p.m. to 6 a.m. from night to early morning, the priority is set so that the spray is always stopped during the stop time zone. If the priority of the stop time zone is set higher than the spray time related to the work, spraying can be stopped at 9 p.m. if work is also performed during this time and the spray time overlaps with the stop time zone. In this way, the forced stop time of spraying according to the stop time zone is set. In addition, the implementation requirements may be selectively set to the nozzle 144 that performs spraying in order to adjust the spray amount. For example, the spray amount may be controlled by determining the required spray amount according to the work conditions and selecting the number of nozzles 144 that perform spraying. Alternatively, the system may be configured with multiple nozzles 144 with different opening sizes, and the spray amount may be controlled by selecting the nozzle that performs spraying according to the nozzle opening size and the required spray amount. As described above, the setting unit 114 may set the implementation requirements of the spray conditions appropriately according to the analysis data, weather conditions, and work conditions.

[0043] The control unit 116 determines whether or not the judgment criteria of the spray conditions are met using the weather data and work data received by the reception unit 112 as input parameters. If it is determined that the judgment criteria are met, spraying of the functional agent from the nozzle 144 to the outside of the facility is performed so as to satisfy the implementation requirements of the spray conditions. If it is determined that the judgment criteria are not met, the control process is repeated every time input parameters (analysis data, or weather data and work data) are received.

[0044] (Effects of odor improvement system) Next, the operation of the odor improvement system 100 will be described.

[0045] FIG. 5 is a sequence diagram showing the flow of processing by the odor improvement system 100. In this processing, the control device 110 performs control processing by having the CPU 11 read out a control program from the ROM 12 or storage 14, expand it in the RAM 13, and execute it. The CPU 11 of the control device 110 executes each process as each processing unit. This processing may be executed as a routine every time a certain amount of time has elapsed. It may also be executed each time an analysis of the simulation environment 130 is generated. It may also be executed from an intermediate step, such as the reception of weather data and work data, and can be executed with appropriate modifications. The control program is an example of an odor improvement program of the technology of the present disclosure.

[0046] In step S100, the simulation environment 130 executes a simulation of the diffusion state of the facility using the location conditions and weather forecast related to the facility, and generates analysis data.

[0047] In step S102, the simulation environment 130 transmits the generated analysis data to the control device 110. The reception unit 112 of the control device 110 receives the analysis data.

[0048] In step S104, the setting unit 114 sets the spray conditions according to the analysis data, the weather conditions, and the work conditions. The spray conditions are the above-mentioned judgment criteria and implementation requirements. In this process, the setting may be adjusted by appropriately accepting the input of the operator.

[0049] In step S106, the reception unit 112 transmits the weather data observed by the weather observation device 120 to the control device 110. The reception unit 112 of the control device 110 receives the weather data.

[0050] In step S108, the accepting unit 112 accepts input of task data from the worker.

[0051] In step S110, the control unit 116 determines whether or not the judgment criteria for the spray conditions set in step S104 are met, using the weather data and work data received in steps S106 and S108 as input parameters. If it is determined that the judgment criteria are met, the process proceeds to step S112. If it is determined that the judgment criteria are not met, the process ends without performing spraying. At this time, the judgment may be made using a plurality of judgment criteria, the first judgment criterion and the second judgment criterion.

[0052] In step S112, the control unit 116 creates spray execution information using the weather data and work data received in steps S106 and S108 as input parameters to satisfy the implementation requirements of the spray conditions set in step S104. The spray execution information is information that defines the start time and stop time of spraying.

[0053] In step S114, the control unit 116 transmits a spray start instruction to the spray device 140 based on the spray execution information.

[0054] In step S116, the spray device 140 sprays the active agent stored in the pump 142 from the nozzle 144 based on the received start command.

[0055] In step S118, the control unit 116 determines whether it is the stop time of spraying according to the spray execution information. If it is the stop time, the process proceeds to step S120, and if it is not the stop time, this step is repeated at regular intervals.

[0056] In step S120, the control unit 116 transmits an instruction to stop spraying to the spray device 140 based on the spray execution information.

[0057] In step S122, the spray device 140 stops spraying the functional agent based on the received stop instruction. In this manner, spraying of the functional agent outside the facility in the odor improvement system 100 is performed.

[0058] In addition, when the spray conditions are updated in real time according to the analysis data, the control device 110 may periodically execute the above processing sequence, receive the analysis data, weather data, and work data, and appropriately update the spray conditions and spray execution information. Also, the process may be executed from an intermediate processing step according to the input data.

[0059] As described above, the odor abatement system 100 of this embodiment can efficiently reduce odors around a facility.

[0060] In the above embodiment, the control device 110 receives analysis data, weather conditions, and work conditions as inputs, and sets parameters for the spray conditions in the setting unit 114. However, the present invention is not limited to this. For example, the control device 110 may have a simple function of simply controlling the ON / OFF of spraying in response to inputs. In this case, the odor improvement system 100 may be configured to include only the control device 110, which is the control unit 116, and the spray device 140.

[0061] Also, the spray conditions may be determined using the weather conditions and work conditions input by the worker without using the analysis data. In this case, the odor improvement system 100 may be configured with a control device 110, a weather observation device 120 (or an external weather information service), and a spray device 140.

[0062] In the above embodiment, the control process executed by the CPU after reading the software (program) may be executed by various processors other than the CPU. In this case, examples of the processor include a PLD (Programmable Logic Device) such as an FPGA (Field-Programmable Gate Array) whose circuit configuration can be changed after manufacture, and a dedicated electric circuit such as an ASIC (Application Specific Integrated Circuit) which is a processor having a circuit configuration designed exclusively for executing a specific process. The control process may be executed by one of these various processors, or may be executed by a combination of two or more processors of the same or different types (for example, a plurality of FPGAs, a combination of a CPU and an FPGA, etc.). The hardware structure of these various processors is, more specifically, an electric circuit that combines circuit elements such as semiconductor elements.

[0063] In the above embodiment, the control program is pre-stored (installed) in the storage 14, but the present invention is not limited to this. The program may be provided in a form stored in a non-transitory storage medium such as a CD-ROM (Compact Disk Read Only Memory), a DVD-ROM (Digital Versatile Disk Read Only Memory), or a USB (Universal Serial Bus) memory. The program may be downloaded from an external device via a network. [Explanation of symbols]
