The estimation logic of the above water content information H will be described according to the flow of FIGS. 5 to 6.

In step S0 of FIGS. 5 to 6, information on the provided woody biomass F is registered in advance in the provided wood database Df by the provider or the like. For example, the provider accesses the registration screen (see FIG. 2A) via a communication network (not shown) such as the Internet, inputs necessary information on the registration screen, and then presses the registration button (DB registration in FIG. 2A). By clicking, the information on the provided woody biomass F may be registered.

In this step, for example, when an arbitrary provider obtains a new provided woody biomass F, or when a provider type A registers or updates a measurement result of a new water-containing information H, information on the provided woody biomass F is used. When it becomes necessary to register (renew) the information, it will be done by the provider as appropriate.

After that, the subsequent steps S1 to S7 are performed triggered by a request (search request) from the recipient or the like. However, the present invention is not limited to this embodiment. For example, the distribution support device 1 may periodically perform steps S1 to S7, and the information field for storing the estimated water content information E of the wood record Rf may be updated by the calculated estimated water content information E. .. It is possible to present the estimated water content information E with better response.

In step S1, the information of the provided woody biomass F, which is the estimation target of the water content information H, is acquired from the provided wood database Df in response to the input of the wood search condition Qf by the recipient or the like (estimation target information acquisition unit 21). .. Then, in step S2, the reference wood database Dp is searched by the past search condition Qp including the wood information B (fuel type Bt, tree species Bk) and the storage information S regarding the provided woody biomass F of the estimation target acquired in step S1. Based on the result of this search, the reference water-containing transition information Hr is acquired in step S3 (reference water-containing transition acquisition unit 22). Further, in steps S4 to S6, the calculation (estimation) of the estimated water content information E at the estimation target time te is performed based on the reference water content transition information Hr acquired in step S3 (water content information estimation unit 23).

As will be described later, as shown in FIGS. 5 to 6, the past search condition Qp for searching the reference wood database Dp includes the past environmental information (past environmental information Wp described later) in the storage location Sp. You may (see step S2a). Further, the estimation may be performed through the calculation of the decrease rate V of the water content (value of the water content information H) (see step S4). Further, in the embodiment shown in FIGS. 5 to 6, in step S7, the estimated value of the low calorific value (estimated low calorific value) is calculated by converting the estimated water content information E, and the provided wood is calculated based on the calculation result. It is configured to register and update information in an information field for storing the estimated low calorific value and the estimated water content information E in the database Df, respectively.

The transition of the water content information H updated by the execution of the estimation logic of the water content information H shown in FIGS. 5 to 6 described above will be specifically described with reference to FIGS. 7 to 9. 7 to 9 are diagrams showing the transition of the water content information H (measured water content information Hm) and the estimated water content information E registered in the provided wood database Df according to the embodiment of the present invention, and FIG. 7 is a diagram showing the transition of the estimated water content information E. In the case of type A (registering a plurality of measured water content information Hm), FIG. 8 shows the provider type B (registering one measured water content information Hm), and FIG. 9 shows the provider type C (registering the measured water content information Hm). The cases of are shown respectively.

In addition, although the information of the provided woody biomass F provided (sold) by one of the providers, XX wood sales company, is exemplified in FIGS. 7 to 9, the upper column shown in the figure is provided. The transition of the registered contents of the wood database Df is shown. On the other hand, the lower column shows the contents of each of the multiple registration operations of the information on the woody biomass F provided to the provided wood database Df performed by the person in charge of the provider, and the estimation of the water content (moisture content information H). The result is shown. At this time, for the sake of simplification of the explanation, it is assumed that the wood information B of the registered fuel is the same. Further, the wood weight in the following description is the total weight of the provided woody biomass F containing water. On the other hand, the fuel weight is the weight obtained by subtracting water from the wood weight, and is calculated by the formula of wood weight × (1-moisture content).

In the embodiment shown in FIGS. 7 to 9, at time t0, the provided wood database Df does not have the registration (DB registration) of the provided woody biomass F provided by the XX wood sales company. As a result of the provider inputting the information of the first provided woody biomass Fa by executing the above-mentioned step S0 (1st) at an arbitrary time (11/10) thereafter, the information of the first provided woody biomass Fa is set at time t1. Is registered in the DB. In other words, the wood record Rf relating to the first provided woody biomass Fa has been added (created) to the provided wood database Df. More specifically, FIGS. 7 to 8 correspond to the cases of the donor types A to B, in which the donor sets the initial measurement moisture content information Hm of the first provided woody biomass Fa to 30% and the wood weight. As a result of inputting at 14t, the information of the first provided woody biomass Fa at time t1 is registered in the DB with a water content of 30% and a fuel weight of 10t (≈14t × {1-0.3}). On the other hand, FIG. 9 corresponds to the case of the provider type C in which the measured water content information Hm is not registered, and as a result of inputting the wood weight of the first donated woody biomass Fa at 14 tons, the first provided woody biomass Fa at time t1. The information is registered in the DB with a water content (estimated value) of 30% and a fuel weight of 10 tons.

The next day (11/11: between time t1 and time t2), as a result of the provider inputting the information of the second provided woody biomass Fb by executing the second step S0 (2nd), at time t2, the first Along with the information on the provided woody biomass Fa, the information on the second provided woody biomass Fb is also registered in the DB. More specifically, in the case of donor types A and B (FIGS. 7 to 8), the donor inputs the measured water content information Hm (first time) for the second donor woody biomass Fb at 20% and the wood weight at 6t. As a result, the information of the second provided woody biomass Fb at time t2 is registered in the DB with a water content of 20% and a fuel weight of 5t (≈6t × {1-0.2}). In the case of donor type C (FIG. 9), the result of inputting the wood weight of the second donated woody biomass Fb at 6 tons (no water content input), the information of the second provided woody biomass Fb at time t2 is the water content. (Estimated value) is 20%, fuel weight is 5t, and it is registered in the DB. On the other hand, as a result of updating the water content of the first provided woody biomass Fa with the estimated value in the donor types B and C, the water content (estimated value) was 27% (decreased by 3%) and the fuel weight was 27% (decreased by 3%) at time t2. It is registered in the DB at 10t.

Further, the next day (11/12: between time t2 and time t3), by executing the third step S0 (3rd), the provider inputs the information of the third provided woody biomass Fc, and as a result, the third provided woody material Biomass Fc has a moisture content of 24% and a wood weight of 6.5 tons and is registered in the DB (provider type C is an estimated value as described above). Therefore, for the third provided woody biomass Fc, the water content is 24% and the fuel weight is 5t (≈6.5t × {1-0.24}), which is registered in the DB. The moisture content of the provided woody biomass Fa is 24% by updating the measured value (FIG. 7) or the estimated value (FIGS. 8 to 9), which is the same as the moisture content of the third provided woody biomass Fc. .. Therefore, in the present embodiment, the information of the first provided woody biomass Fa and the information of the third provided woody biomass Fc are integrated, so that the information of the provided woody biomass F (Fac) after the integration contains water at time t3. The rate is 24% and the fuel weight is 15t. On the other hand, as a result of updating the estimated value of water content in the information of the second provided woody biomass Fb, the water content (estimated value) was 18% (2% decrease) and the fuel weight was registered in the DB at 5t at time t3. There is. In this way, by managing the wood information B and the water content information H together by integrating the same provided woody biomass, the total stock amount of equivalent (homogeneous) fuel becomes clear, and the amount requested by the recipient can be met. It will be possible to respond widely.

Then, on the next day (11/13), the provider or the like executes the fourth step S0 (4th), so that the information of the fourth provided woody biomass Fd (moisture content 10%, wood weight 10t) is input. Will be done. Although the illustration corresponding to this is omitted, the DB is registered in the same manner as described above, and the water content of the already registered provided woody biomass F is updated. In the above-described embodiment, the provider type A (measurement of the water content multiple times) manages only the measured value of the water content, but the estimated value is calculated and managed among the measured values of the plurality of times. You may. Further, although an example in which the fuel weight is used as the weight information stored in the provided wood database Df is shown, the wood weight input by the provider may be used as it is as the weight information.

For example, when the amount of water contained in woody biomass is large, the proportion of the part that functions as fuel in the whole wood is relatively small. Although it has a great influence on the combustion capacity of biomass, it has the property of changing from moment to moment depending on the storage method and the number of storage days.
According to the above configuration, the distribution support device 1 is the provided woody biomass F stored (stored) in the provided wood database Df for provision to the recipient (for example, sold to the purchaser of the woody biomass). The water content information H (for example, water content) is estimated using the reference wood database Dp. This makes it possible for the recipient of the woody biomass or the like to timely grasp the water content information H of the woody biomass, which changes from moment to moment depending on the storage method, the number of storage days, and the like. In this way, by being able to grasp the water content information H in a timely manner, it is also possible to grasp the combustion capacity and amount of fuel, which is an important factor for the stable and efficient operation of the woody biomass utilization plant. It becomes. Furthermore, since fuel costs generally account for most of the operating costs of woody biomass utilization plants, it is possible for recipients who operate the plant to properly assess the value of woody biomass as fuel before procuring it. , It has a great effect of stabilizing plant operation.

Further, when the information of the provided woody biomass F stored in the provided wood database Df is displayed and output on a display or the like in response to the request of the recipient, for example, the estimated water content information E is also output to the recipient. On the other hand, it is configured to present the water content information H. Therefore, by confirming the output information of the distribution support device 1, the recipient can quickly know whether or not it is possible to receive the provision of woody biomass having a desired water content. , It is possible to select woody biomass based on the water content. Therefore, even when sudden procurement is required due to an increase in heat demand, it is possible to easily procure appropriate woody biomass by checking the output information of the distribution support device 1. Further, the provider of woody biomass registers the information of the woody biomass fuel provided by himself / herself in the provided wood database Df, so that the wood information B including the water content information H will be presented to the recipient. It is possible to increase the possibility of provision to recipients who have not been provided. Therefore, it is possible to promote the distribution of woody biomass.

In some embodiments, as shown in FIG. 2A, the wood information B further includes a place of acquisition of the donated woody biomass F. On the registration screen of the embodiment shown in FIG. 2A, it is possible to input an address such as a logging area as an acquisition place.
According to the above configuration, it is possible to refer to the provided woody biomass F having a similar acquisition location such as the logging area of the provided woody biomass F. Since woody biomass has regional differences in properties such as different specific gravities depending on the growing area even for the same tree species Bk, it is possible to estimate the water content information H with higher accuracy by referring to woody biomass having closer properties.

Next, the calculation (estimation) method of the estimated water content information E will be described more specifically.
In some embodiments, as shown in FIGS. 5 to 6, the water content information estimation unit 23 includes a decrease rate calculation unit 24 (step S4), a starting point water content information acquisition unit 25 (step S5), and an estimation execution unit. 26 (step S6), and as will be described later, the estimated water content information E at the estimation target time te is calculated assuming that the water content information H decreases at the decrease rate V from the starting point water content information Ho. Since the water content is expected to increase depending on the environment, the decrease rate V may be a negative value. Each of the above functional parts will be described.

The decrease rate calculation unit 24 is a functional unit that calculates the decrease rate V of the value of the water content information H based on the reference water content transition information Hr acquired by the reference water content transition acquisition unit 22, and is a functional unit that calculates the decrease rate V of the value of the water content information H. Executes the processing of. In some embodiments, the rate of decline calculation unit 24 predicts the water content transition information Ht of the provided woody biomass F, which is the estimation target of the water content information H, by performing regression analysis on the reference water content transition information Hr described above. In addition to obtaining the regression line to be, the rate of change (slope) of the obtained regression line may be calculated as the rate of decrease V. As described above, the reference water content transition information Hr is the water content transition information Ht (past data) of one or more reference woody biomass Fr whose water content transition information Ht is expected to be similar to the provided woody biomass F which is the estimation target of the water content information H. ). Therefore, for example, when the reference water content transition information Hr is plotted on a graph in which the horizontal axis is the time axis and the vertical axis is the measured value of the water content, the error between the regression line to be obtained and each plot point is minimized. To determine the regression line (least squares method). In some other embodiments, the decrease rate calculation unit 24 may calculate statistical values such as the average and the mode of the decrease rate V in each of the plurality of reference water-containing transition information Hr as the decrease rate V to be obtained. good. In some other embodiments, when the water content transition information Ht (reference water content transition information Hr) of 1 is acquired from the reference wood database Dp as the one having the highest similarity described above, the water content transition information Ht of 1 is obtained. The above-mentioned decrease rate V may be calculated based on the water content transition information Ht, such as calculating the statistical value of.

The starting point water-containing information acquisition unit 25 is a functional unit that acquires the starting point water-containing information Ho, which is the water-containing information H at the estimated starting point time to, which is a predetermined time before the estimation target time te. Execute the process. In some embodiments, as shown in FIG. 5, the starting point water containing information acquisition unit 25 may acquire the starting point water containing information Ho from the provided wood database Df. In some other embodiments, as shown in FIG. 6, the starting point water containing information acquisition unit 25 may acquire the starting point water containing information Ho by estimation. Details of these will be described later.

Further, the estimation execution unit 26 is a functional unit that calculates the estimated water content information E at the estimation target time te based on the starting point water content information Ho and the decrease speed V, and executes the process of step S6 of FIGS. 5 to 6. do. Specifically, the calculation is performed on the assumption that the value of the water-containing information H decreases at the decrease rate V from the estimated starting point time to of the starting point water-containing information Ho. For example, assuming that the rate of decrease V is the rate of decrease in the water content per unit time (% / hour), the water content after an arbitrary time x has elapsed from the estimated starting time to is Ho (1-V × x). Can be calculated. Therefore, the estimation execution unit 26 calculates the calculation formula of the estimated water content information E = Ho (1-V × x) assuming that the estimation target time te has elapsed by the time x from the estimated starting point time to.

According to the above configuration, for example, regression analysis is performed on the reference water content transition information Hr of the reference woody biomass Fr acquired from the reference wood database Dp based on the wood information B and the storage information S of the provided woody biomass F. The decrease rate V is calculated by. Further, the estimated water content information E at the estimation target time te is calculated assuming that the value of the water content information H (water content, etc.) decreases at the decrease rate V from the starting point water content information Ho obtained by, for example, measurement or estimation. By using the reference water content transition information Hr in this way, the estimated water content information E can be calculated.

As described above, in some embodiments, as shown in FIG. 5, the starting point water containing information acquisition unit 25 acquires the starting point water containing information Ho from the provided wood database Df. In the embodiment shown in FIG. 5, the provided wood database Df further stores the measured water-containing information Hm, which is the measured water-containing information H of the provided woody biomass F. That is, the wood record Rf has an information field for storing the measured water content information Hm and the measured time tm. Information is registered in advance in these information fields by providers (types A and B) who are supposed to register the measured water content information Hm. Then, the starting point water-containing information acquisition unit 25 sets the latest measured water-containing information Hm acquired from the provided wood database Df as the above-mentioned starting point water-containing information Ho, and sets the measurement time tm as the estimated starting time to.

According to the above configuration, the starting point water content information Ho is the measured water content information Hm measured before the estimation, and the estimated water content information E is the value of the water content information H at the decrease rate V from the measured water content information Hm. Is calculated as decreasing. By calculating the estimated water content information E at the estimation target time te from the measured value in this way, the estimation accuracy can be improved.

In some other embodiments, as shown in FIG. 6, the starting point water containing information acquisition unit 25 acquires the starting point water containing information Ho by estimation. More specifically, the wood information B further includes a raw material-derived Bd which is information on the origin of the raw material of the provided woody biomass F processed according to the fuel type Bt (see FIG. 4 (A)). That is, the wood record Rf has an information field for storing the raw material-derived Bd, and the raw material-derived Bd is registered by the provider or the like. Therefore, by adding the raw material-derived Bd to the wood search condition Qf, the reference water-containing transition acquisition unit 22 refers to the water-containing transition information Ht in which the wood information B including the raw material-derived Bd and the storage information S match (same or similar). Obtained from database Dp. Further, as shown in FIG. 6, the distribution support device 1 has the water content information H at the estimated starting point time to of the provided woody biomass F to be estimated based on the first measured value of the water content information H possessed by the reference water content transition information Hr. Further, a starting point water containing information estimation unit 27 for calculating the estimated starting point water containing information Eo, which is an estimated value of the above, is provided. Then, the above-mentioned starting point water-containing information acquisition unit 25 acquires the estimated starting point water-containing information Eo calculated by the starting point water-containing information estimation unit 27 as the starting point water-containing information Ho. For example, the starting point water content information estimation unit 27 calculates the average value of the first measured values in one or more water content transition information Ht (past data) constituting the reference water content transition information Hr, obtains the mode, and the like. , The estimated starting point water content information Eo is calculated by calculating the statistical value.

In the embodiment shown in FIG. 6, the time corresponding to the starting point water-containing information Ho is the acquisition date and time of the registration screen (see FIG. 2A). The storage destination of the estimated starting point water-containing information Eo and its corresponding time (acquisition date and time) may be an information field for storing the measured water-containing information Hm and the measured time tm possessed by the wood record Rf. If it is necessary to indicate whether the stored information is a measured value or an estimated value, an information field for storing a flag for that purpose may be provided in. Alternatively, a dedicated information field for storing such information may be provided and stored. Further, the calculation by the starting point water content information estimation unit 27 is executed when the information of the provided woody biomass F is registered in the provided wood database Df and there is no information of the measured water content information Hm. Therefore, as shown in FIG. 6, when the water content information H is updated with an estimated value after that (second time or later), the previous origin water content information Ho and the corresponding time stored in the provided wood database Df and the corresponding time, and step S4 The estimated water content information E is calculated based on the decrease rate V calculated in.

According to the above configuration, the starting point water content information Ho used to calculate the estimated water content information E using the decrease rate V is, for example, the estimated value of the water content information H when the provided woody biomass F or the like is obtained, or , It is an estimated value such as the last time stored in the reference wood database Dp. That is, the calculation of the estimated water content information E is performed from the reference wood database Dp to the reference water content transition information Hr acquired from the reference wood database Dp based on the wood information B including the raw material-derived Bd of the provided woody biomass F and the storage information S. Do it based on. In this way, by acquiring the reference water content transition information Hr in consideration of the raw material-derived Bd, even when there is no measured value of the water content information H (provider type C), the water content information H of the provided woody biomass F is obtained. Can be estimated appropriately.

Next, some embodiments relating to the reference water-containing transition acquisition unit 22 will be described.

For example, the estimated arrival water content information H1 is calculated by calculating statistical values such as calculating the average value of one or more arrival water content record information Hd constituting the reference arrival water content information Hdr or obtaining the mode value. May be calculated. In addition, the similarity of all the various elements including the wood information B associated with each arrival water content record information Hd was determined by a known method such as cluster analysis, and the most similar result was obtained at the arrival water content record. The information Hd may be the estimated arrival water content information H1.
