Description

  The present invention relates to an insect repellent design support system, and more particularly to an insect repellent design support system that is suitable when it is desired to quantitatively grasp the extent to which insects easily enter a room constituting a building.

  In a facility that processes or cooks food, careful management is necessary to ensure the hygiene of the processed or cooked food. One of the management items is insect control. Insufficient insect control measures may cause insects to enter the food during processing or cooking. It is unsanitary when foods with insects are on the market. Especially when insects are mixed in their natural form, they will be unpopular with the consumers and the trust of the companies that manage the facilities will be lost. For this reason, in this type of facility, in order to prevent insects from invading, contrivances have been made to the structure and management of doorways and openings, which are contact points with the outdoors.

In addition, in order to ensure adequate insect control measures, it is important to accurately obtain information such as insect ecology and occurrence status, and to establish an appropriate management system based on such information. Patent Document 1 discloses an information processing apparatus that can acquire various types of pest information from such a viewpoint and can search for necessary insect control measures. Patent Document 2 discloses a cooking hygiene management system that can quickly eliminate an abnormal state due to the occurrence of pests and maintain a high level of hygiene management.

  Hereinafter, a specific example of this embodiment will be described. FIG. 2 is a plan view illustrating the layout of a food processing plant building to which the present invention is applied. The building 20 is composed of a plurality of rooms including a raw material receiving room 22, a raw material storage room 24, a food processing room 26, a product storage room 28, and a product shipping room 30.

  The raw material receiving chamber 22 is provided with an entrance 32 that leads to the outdoors. This entrance / exit 32 is a shutter, has an opening area through which the material transport vehicle can enter and exit, and is opened only when the material transport vehicle enters / exits, and is closed at other times. An entrance / exit 34 is provided in the partition between the raw material receiving chamber 22 and the raw material storage chamber 24. The entrance / exit 34 is an air curtain, and has an opening area where the raw material received in the raw material receiving chamber 22 can be carried to the raw material storage chamber 24 by a forklift and is always open. An entrance 46 is provided in the partition between the raw material receiving chamber 22 and the product shipping chamber 30. The entrance 46 is a door through which an operator enters and exits the rooms as necessary, and is closed when not necessary.

  An entrance / exit 36 is provided in the partition between the raw material storage chamber 24 and the food processing chamber 26. In this entrance / exit 36, a flexible transparent sheet is hung down in order to convey the raw material, so that workers and carts can freely enter and exit at all times. An entrance 42 is provided in the partition between the raw material storage chamber 24 and the product storage chamber 28. This entrance / exit 42 is a door through which an operator enters and exits the rooms as necessary, and is closed except when necessary.

  The food processing chamber 26 is provided with an entrance 38 that leads to the outdoors. This entrance / exit 38 is a door through which workers enter and exit or carry in / out equipment, and is closed except when necessary.

  Entrances 40 and 41 are provided in the partition between the food processing chamber 26 and the product storage chamber 28. The doorway 40 is a door through which workers enter and exit, and is closed except when necessary. The entrance / exit 41 is an entrance / exit for conveying a product by the raw material conveyor 50 arrange | positioned through between both chambers, and the flexible sheet | seat is hung down. An entrance 44 is provided in the partition between the product storage room 28 and the product shipping room 30. This entrance / exit 44 is an air curtain, and has an opening area that allows the product stored in the product storage chamber 28 to be carried to the product shipping chamber 30 by a forklift, and is always open. The product shipping room 30 is provided with an entrance 48 leading to the outdoors. This doorway 48 is a shutter, has an opening area through which the product transport vehicle can enter and exit, and is opened only when the product transport vehicle enters and exits, and is closed at other times.

  FIG. 3 shows the floor area and the entrance / exit of each room. In the description of the position of the entrance / exit, the numerical value on the left side of / is the sign of the entrance / exit shown in FIG. 2, and the right side of / means the sign of the other party's chamber. For example, the raw material receiving chamber 22 has a total of three inlets / outlets, that is, an inlet / outlet 32 leading to the outdoors, an inlet / outlet 34 leading to the raw material storage chamber 24, and an inlet / outlet 46 leading to the product shipping chamber 30.

FIG. 4 shows the specifications of each doorway. For example, the type of the entrance / exit 32 is a shutter, the opening area when fully opened is 8.0 m ² , the door is opened at an average frequency of 50 times a day, and the opening time per time is an average of 100 seconds. Show. Further, the type of the entrance / exit 34 is an air curtain, and the opening area is 4.0 m ² , indicating that it is always open.

  In the input unit 10 shown in FIG. 1, as the facility specifications of each room, the floor area and the position of the entrance / exit shown in FIG. 3, the structure of the entrance / exit shown in FIG. 4 (model and opening area), and its opening information (Opening frequency and opening time per time) are input. In addition, as shown in FIG. 5, the insect passage coefficient corresponding to the entrance / exit model is stored in the storage unit 16 shown in FIG. 1 in advance as a database. This insect passage coefficient is based on the degree to which flying insects such as moths, mosquitoes, planthoppers, moths, cockroaches, etc. pass easily through the doorway and enter the room. It is a value obtained empirically with the fully opened state as the reference (1.0). Based on the facility specifications of each room input to the input unit 10 and the data stored in the storage unit 16, the calculation unit 12 calculates the insect passage coefficient, the opening rate, and the opening time rate at each doorway as shown in FIG. Calculate.

That is, the doorway model is input as shown in FIG. 4, and the insect passage coefficient for the doorway type is stored as shown in FIG. Can be specified. The opening ratio is a ratio of the opening area of the entrance to the floor area of each room. Since the floor area of each room is found from FIG. 3 and the opening area of each doorway is found from FIG. 4, the calculation unit 12 can immediately calculate the opening ratio of each doorway. For example, the entrance / exit 32 is provided in the raw material receiving chamber 22, and the floor area of the raw material receiving chamber 22 is 100 m ² and the opening area of the inlet / outlet 32 is 8.0 m ^2. 0.0 / 100 = 0.080. Further, the entrance / exit 34 is provided between the raw material receiving chamber 22 and the raw material storage chamber 24, and the floor area of the raw material receiving chamber 22 is 100 m ² , the floor area of the raw material storage chamber 24 is 300 m ² , and the opening area of the entrance / exit 34 is 4. 0.0 m ² . Therefore, the opening ratio of the entrance / exit 32 to the raw material receiving chamber 22 is 4.0 / 100 = 0.040, and the opening ratio of the entrance / exit 32 to the raw material storage chamber 24 is 4.0 / 300 = 0.013.

  The open time rate is the ratio of the time at which each doorway is opened to the standard time when the factory is active. Since the opening time of each doorway per day can be obtained by multiplying the opening frequency shown in FIG. 4 by the opening time per time, the calculation unit 12 can immediately calculate the opening time rate of each doorway. For example, since the opening frequency of the doorway 32 is 50 times / day and the opening time per time is 100 seconds, the opening time of the doorway per day is calculated as 50 × 100 / 3,600 = 1.4 hours. Is done. Therefore, if the standard time during which the factory is active is 10 hours, for example, the opening time rate of the entrance 32 is 1.4 / 10 = 0.14. On the other hand, since the entrance / exit 34 is always open, the opening time rate is 1.0.

  When the insect passage coefficient, opening ratio, and opening time ratio of each doorway are obtained as shown in FIG. 6 in the above-described manner, the calculation unit 12 calculates the degree to which an insect easily enters the room next as the insect intrusion level. The insect invasion level is a value obtained by indexing the possibility of insects entering the room from the entrance / exit of each room, and specifically, by multiplying the insect passage coefficient, opening rate, and opening time rate of each entrance / exit. Desired. When a room has a plurality of doorways, the insect intrusion level of the entire room is obtained by adding the insect intrusion levels from the doorways. In addition, between the multiple rooms that make up a building, the insect intrusion level of each room can be determined by multiplying the insect intrusion level of the adjacent room by the insect passage coefficient, opening rate, and opening time rate of each doorway. Desired.

FIG. 7 shows the insect invasion level of each room obtained by the above concept. For example, the insect intrusion level of the raw material arrival chamber 22 is 0.8 × 0.080 × 0.14 = 9.0 × 10 ⁻³ by multiplying the insect passage coefficient, the opening rate, and the opening time rate at the entrance 32. Become. The insect intrusion level from the doorway 48 of the product shipping room 30 is 0.8 × 0.080 × 0.08 = 5.1 × 10 ⁻³ by multiplying the insect passage coefficient, the opening ratio, and the opening time ratio. . In addition, there is a possibility that insects may enter the product shipping room 30 from the entrance / exit 46 based on the difference from the insect entry level of the raw material arrival room 22. The insect passage coefficient at 46, the aperture ratio, and the open time ratio are multiplied to be 9.0 × 10 ⁻³ × 1.0 × 0.018 × 0.01 = 1.6 × 10 ⁻⁶ . As described above, when there are a plurality of doorways in the room, the insect intrusion level from each doorway is added. However, in this product shipping room 30, the insect intrusion level from the entrance / exit 48 is overwhelmingly large, and the insect invasion level from the entrance / exit 46 is a negligible value and can be made substantially zero. Therefore, in the product shipping room 30, the insect intrusion level from the doorway 48 is set to 5.1 × 10 ⁻³ .

The insect invasion level of the raw material storage chamber 24 is 9.0 × 10 ⁻³ × 0.5 × 0 by multiplying the insect invasion level of the raw material receiving chamber 22 by the insect passage coefficient, the opening rate, and the opening time rate at the entrance / exit 34. .013 × 1.00 = 5.9 × 10 ⁻⁵ . Further, although there are four entrances / exits in the food processing chamber 26, the insect intrusion level from the entrances 36, 40, 41 is a negligible value and can be substantially zero. For this reason, the insect intrusion level of the food processing chamber 26 is aggregated to the value from the entrance / exit 38, and the insect passage coefficient, the opening ratio, and the opening time ratio are multiplied by 1.0 × 0.002 × 0.03 = It becomes 6.0 × 10 ⁻⁵ . The product storage room 28 also has four entrances, but the insect intrusion level from the entrances 40, 41, and 42 is a negligible value and can be substantially zero. For this reason, the insect intrusion level in the product storage room 28 is integrated into the value from the entrance 44. Therefore, the insect intrusion level in the product storage room 28 is 5.1 × 10 ⁻³ × 0.5 by multiplying the insect intrusion level in the product shipping chamber 30 by the insect passage coefficient, the opening rate, and the opening time rate at the entrance / exit 44. × 0.013 × 1.00 = 3.3 × 10 ⁻⁵

  The calculation results as described above are output as a diagram or a table from the output unit 14 of FIG. As a result, it is possible to determine whether the output level of the insect invasion in each room is good or bad. The storage unit 16 may store the standard insect intrusion level of the room for each application, and display a warning when the calculated insect intrusion level of the room exceeds the standard value. If there is a room with an inappropriate insect intrusion level, the user of the system may change at least a part of the facility specifications and re-enter it. In other words, it is possible to repeat the calculation until a satisfactory output is obtained by reexamining the structure of the doorway and the open state, changing the facility specifications in a direction to improve the insect intrusion level, and re-inputting.

FIG. 8 is an explanatory diagram when the facility specifications are changed. That is, FIG. 7 assumes that the insect intrusion level of each food room 26 is high at the obtained insect intrusion level of each room and needs to be improved. Therefore, in FIG. 8, a front chamber 60 (floor area 4 m ² ) is attached to the entrance / exit 38 which is a main path for insect invasion, and an entrance / exit 62 is provided in the front chamber 60. The specification of the entrance / exit 62 is the same as that of the entrance / exit 38. Then, the insect passage coefficient of the entrance / exit 62 is 1.0, the opening ratio is 1.8 / 4.0 = 0.45, the opening time ratio is 0.03, and the insect intrusion level of the front chamber 60 is multiplied by these values. It becomes 1.4 × 10 ⁻² . Then, the insect intrusion level from the entrance / exit 38 of the food processing chamber 26 is 1.4 × 10 ⁻² × by multiplying the insect intrusion level of the front chamber 60 by the insect passage coefficient, the opening rate, and the opening time rate at the entrance 38. 1.0 × 0.002 × 0.03 = 8.4 × 10 ⁻⁷ . This result shows that the insect invasion level is reduced by five orders of magnitude compared to before the improvement, which shows a satisfactory improvement effect. In addition, if the insect intrusion level from the entrance / exit 38 of the food processing chamber 26 is thus reduced, the insect intrusion level from the other entrance / exit of the food processing chamber 26 cannot be ignored. The calculation result shows that the insect intrusion level from the entrance / exit 36 is 0.9 × 10 ⁻⁷ , and the insect intrusion level from the entrance / exit 40, 41 is substantially zero. Therefore, the calculation result that the total insect invasion level of the entire food processing chamber 26 is 9.3 × 10 ⁻⁷ is obtained.

  As described above, according to the insect repellent design support system of this embodiment, when a facility specification of a room constituting a building, for example, an entrance / exit specification is input to the input unit 10, the calculation unit 12 converts the facility specification to the input facility specification. Based on this, the insect penetration level of each room is calculated. The output unit 14 outputs the calculation result of the calculation unit. As a result, it is possible to quantitatively grasp the extent to which insects easily enter the room. In addition, since the target building is usually composed of a plurality of rooms, it is possible to quantitatively grasp the degree to which insects easily enter the room for each room. Therefore, this insect repellent design support system is very effective as a tool for determining an appropriate facility specification for insect repellent.

  In the above-described embodiment, the case has been described in which the entrance structure and the opening information thereof are input as facility specifications of each room, and the insect intrusion level of each room is calculated. However, the facility specifications of the room according to the present invention are not limited to the specifications of the entrance / exit. For example, when a window or a ventilation opening to be opened is provided, a more precise insect intrusion level can be calculated by taking these specifications into consideration. Insects gather and change according to the light source. Therefore, if an illumination light source is input as the facility specification of each room and the insect invasion level is corrected according to the type of light source, a more precise insect invasion level can be calculated. FIG. 9 illustrates the insect passage coefficient for the light source of illumination. By storing such data in the storage unit 16 in advance and inputting the illumination light source of each room, the calculation unit 12 can immediately calculate the insect invasion level taking into account the illumination light source. In addition, insects are said to gather and change with room temperature. It is said that insects dislike areas where the room temperature is controlled to 10 ° C. or less, such as a refrigerator, and insects are likely to gather as the temperature rises to about 30 ° C. Therefore, if the management temperature of the room is input as the facility specification of each room and the insect intrusion level is corrected by the room temperature, a more precise insect intrusion level can be calculated. In addition, how insects gather is greatly affected by the location of the target building. Therefore, if the location conditions of the target building are input and the insect intrusion level is corrected, the insect intrusion level can be calculated more appropriately.

  In the present embodiment, the food processing plant building has been described as the application destination of the insect repellent design support system. However, the insect repellent design support system according to the present invention is not limited to food processing plant buildings, and can be used as a tool for grasping the insect repellent levels of various buildings. For example, it is also effective for diagnosis of buildings that handle food such as restaurants, department store food departments, and kitchen facilities. In addition, it can be used for diagnosis of buildings where many people gather, such as general offices and theaters.
