  First, the configuration of the group management control system according to the first embodiment of the present invention will be described with reference to FIG.

  As shown in FIG. 1, a plurality of cars 1 are connected to a single control unit 2 that controls the operation of each car in a communicable manner. The single control unit 2 controls the operation of the car 1 corresponding to each by outputting signals such as acceleration, traveling, deceleration, and stop through a transmission path (not shown). The car 1 is provided with a car load detecting device (not shown), and the car load information detected is transmitted to the single controller 2 through the transmission path.

  Each single control unit 2 that controls the operation of each of the plurality of cars 1 is connected to a group management control device 3. The group management control device 3 controls each single unit control unit 2 to perform group management control of a plurality of cars 1.

  As will be described in detail later, the group management control device 3 includes a group management control unit 6 that outputs various commands to the single control unit 2, and a parameter setting unit 7 that holds a plurality of operation parameters.

  The group management control device 3 is connected to an external environment acquisition unit 5 that is installed independently. The external environment acquisition unit 5 is installed inside or outside the building where the elevator is installed, and includes a thermometer and a hygrometer (not shown), and measures external environment data such as temperature and humidity.

  In this embodiment, external environment data such as temperature and humidity is actually measured as described above. However, in addition to this, the weather on an arbitrary day can be obtained using a transmission line (not shown) such as an Internet line. It is also possible to acquire external environment data such as forecast weather for each hour. Moreover, it is good also as what combines those two or more.

  The external environment data acquired by the external environment acquisition unit 5 is set to be transmitted to the group management control device 3.

  Next, the configuration and operation of each unit provided in the group management control device 3 described above will be specifically described.

  As described above, the group management control device 3 includes the group management control unit 6 and the parameter setting unit 7. The parameter setting unit 7 holds an operation parameter used as default data and one or a plurality of operation parameters used according to the external environment as operation parameters used at the time of going to work or the like. The parameter setting unit 7 determines the status of the external environment from the information input from the external environment acquisition unit 5, and determines an elevator operation parameter according to the status of the external environment when it is determined to be necessary. The determined operation parameter is transmitted to the group management control unit 6, and the group management control unit 6 that has received the operation parameter performs group management control using the operation parameter.

  Next, the operation of the group management control system according to the present embodiment will be described using the flowchart of FIG.

  The group management control system according to the present embodiment changes operation parameters used for group management operations using external environment information such as temperature and humidity. In the present embodiment, as a specific example of the operation parameter to be changed, a case will be described in which the door opening restraint time due to driving at work and the door opening restraint time due to the load setting value are changed. Of course, not only the door opening restraint time and the like but also other set values such as a full load value can be changed according to the external environment information.

  In the present embodiment, the door opening restriction according to the load value in the car is performed on the reference floor based on the operation parameters as shown in FIG. And at the time of specification, as a special setting according to the external environment information, the operation parameter shown in FIG. 3 (a) is changed to the operation parameter shown in FIG. 3 (b), and based on the relationship shown in FIG. 3 (b). The door opening restraint according to the car load value shall be performed on the standard floor. That is, when the operation parameter is specially set, it is determined that the car is full or nearly full with a small car load. Therefore, even when the number of passengers in the car is small, the door opening restraint time can be shortened. This will be specifically described below.

  First, the group management control unit 6 determines whether or not to perform operation control using operation parameters according to external environment information (S1). The timing at which the group management control unit 6 performs the determination varies depending on the operation parameter for which the setting is changed. For example, a change in the setting value of a parameter that is always used in operation control, such as a parameter of a full load setting value that is used at the time of allocation, is performed by setting operation parameters according to external environment information constantly or periodically. In addition, parameter setting values used in a specific operation, such as a parameter indicating the relationship between the door opening restraint time and load setting value used during driving at work, can be changed according to external environment information at the start of the operation. Set the operation parameters. That is, in step 1 of this embodiment, it is determined whether or not to perform operation control using operation parameters according to external environment information depending on whether or not driving is performed at work.

  When it determines with not performing operation control by the operation parameter according to external environment information (NO of S1), the operation control based on the operation parameter in a standard setting is continued (S2). When it is determined that the operation control is performed with the operation parameter according to the external environment information (YES in S1), the group management control unit 6 instructs the parameter setting unit 7 to set the operation parameter according to the external environment information. Is output (S3).

The parameter setting unit 7 that has received the command acquires the external environment information measured and held by the external environment acquisition unit 5 (S4). The parameter setting unit 7 that has acquired the external environment information determines what state the current external environment is in based on the acquired external environment information (S5). The state of the external environment here refers to a state such as temperature and humidity. For example, the following membership function is used to determine the external environment state by the parameter setting unit 7.

In the above _equation 1, T ₀ , T ₁ , T ₂ , and T ₃ indicate the air temperature (° C.) and are values that can be arbitrarily changed. T ₀ and T ₁ are set values related to the temperature “high”, and T ₂ and T ₃ are set values related to the temperature “suitable”. Further, t represents the current temperature measured by the external environment acquisition unit 5.

In the above formula 2, H ₀ , H ₁ , H ₂ , and H ₃ indicate humidity (%) and are values that can be arbitrarily changed. H ₀ and H ₁ are set values relating to humidity “high”, and H ₂ and H ₃ are set values relating to humidity “low”. H indicates the current humidity measured by the external environment acquisition unit 5.

In this embodiment, as shown in FIGS. 4 (a) and 4 (b), predetermined temperature / humidity is determined as an operation parameter in the standard setting, T ₀ = 20 (° C.), T ₁ = 30 (° C.), T ₂ = 20 (° C.), T ₃ = 30 (° C.), H ₀ = 20 (%), H ₁ = 80 (%), H ₂ = 20 (%), and H ₃ = 80 (%).

  The membership function relating to the above equations 1 (1) to (3), that is, the temperature “high”, is a function shown in FIG. 5A, and the function shown in FIG. The function shown in FIG. 5B is a chart of membership functions related to “”. Then, FIG. 5C shows the entire expression 1.

  Further, the function shown in FIG. 6A is a graph of the membership function relating to the above formula 2 (1) to (3), that is, the humidity “high”, and the formula 2 (4) to (6), that is, the humidity. The function shown in FIG. 6B is a graph of the membership function relating to “low”. FIG. 6C shows the entire expression 2.

As shown in Equation 1 above, for example, in the membership function regarding the temperature “high”, when the temperature is lower than T _0, it is determined that the temperature is not high, and the calculated value of the function is 0. Then, assuming that when temperature than T ₁ is higher is determined to be high temperature, the calculated value of the function is 1. On the other hand, in the membership function regarding the temperature “appropriate”, when the temperature is lower than T ₂ , the calculated value of the function is 1 assuming that the temperature is moderate. Then, assuming that when temperature than T ₃ is higher, it is determined that there is no reasonable temperature, calculated values of the function is zero. That is, in FIG. 5C, when the current temperature t is substituted into the above equation 1, the case where the value calculated by each membership function becomes the largest is determined as the current external environment situation.

Similarly, in Equation 2, in the membership function relating to the humidity “high”, for example, when the humidity is lower than H _0, it is determined that the humidity is not high, and the calculated value of the function is 0. Then, assuming that when the humidity than H ₁ is high, it is determined that the humidity is high, the calculated value of the function is 1. On the other hand, in the membership function regarding the humidity “low”, when the humidity is lower than H _2, it is determined that the humidity is low, and the calculated value of the function is 1. When the humidity is higher than H ₃ , the calculated value of the function is 0, assuming that the humidity is not low. That is, in FIG. 6C, when the current humidity h is substituted into the above equation 2, a state where the calculated value is close to 1 is determined as the current external environment state.

  From the above, when the current temperature t is applied to the above equation 1 and the current humidity h is applied to the above equation 2, the value calculated by each membership function is the largest, that is, the calculated value is 1 A case close to is treated as the current situation.

  This will be described more specifically. Consider the case where the temperature and humidity values measured by the external environment acquisition unit 5 are 26 ° C. and 80%, respectively. First, since the temperature is 26 ° C., Equation 1 (2) and Equation 1 (5) are applied. When t = 26 is input to the function shown in Equation 1 (2), 0.6 is calculated, and when t = 26 is input into the function shown in Equation 1 (5), 0.4 is calculated. Here, as a precondition, among the calculated values, the largest value is treated as the current situation, so that the temperature is determined to be “high” when the temperature is 26 ° C.

  Similarly, Equation 2 (1) and Equation 2 (4) are applied when the humidity is 80%. That is, the calculated value of the function of Equation 2 (1) is 1, and the calculated value of the function of Equation 2 (4) is 0. In the same manner as described above, as the precondition, the largest value among the calculated values is treated as the current situation, and therefore, when the humidity is 80%, the humidity is determined to be “high”.

  As described above, the parameter setting unit 7 determines the state of the temperature “high” and the humidity “high” as the current external environment state.

  When the external environment state is determined, the parameter setting unit 7 determines whether or not to set the operation parameter in the special setting based on the determination result of the external environment state performed by itself (S6). In this embodiment, as shown in FIG. 7, the set value of the operation parameter of the load value in the car at the time of going to work and the door opening restraint time is determined from the relationship between the temperature and the humidity. Specifically, when it corresponds to a shaded part, it determines to change the set value of the operation parameter to the special setting. On the other hand, when it does not correspond to the shaded area, the set value of the operation parameter in the current standard setting is maintained. The relationship diagram shown in FIG. 7 specifically shows the following.

  (1) When the temperature is “high” or the humidity is “high”, the set value of the load value in the car and the door opening restraint time are set as special settings.

  (2) When the temperature is “appropriate” and the humidity is “appropriate”, the set values of the car load value and the door opening restraint time are set as standard settings.

  The above-mentioned rules are held in advance by the parameter setting unit 7, and in accordance with this rule, based on the determination result of its own external environmental state and the above rules, the operation of the load value in the car and the door opening restraint time in the operation at work Determines whether the parameter setting is a special setting.

  In the present embodiment, since the parameter setting unit 7 determines that the current external environment state is the temperature “high” and the humidity “high”, it corresponds to the shaded portion shown in FIG. The unit 7 decides to make a special setting.

  When the parameter setting unit 7 determines that the operation parameter for driving at work is not set as a special setting (NO in S6), the operation control based on the operation parameter in the standard setting is continued (S2).

  On the other hand, when the parameter setting unit 7 determines that the operation parameter for driving at work is set as a special setting (YES in S6), the operation parameter in the special setting is transmitted to the group management control unit 6 (S7). Then, the group management control unit 6 controls the operation of the elevator based on the received operation parameter (S8). Specifically, in the case of the present embodiment, the setting of the load value in the car and the door opening restraint time at the time of going to work is changed from the value shown in FIG. 3 (a) to the value shown in FIG. 3 (b). It is assumed that the operation is controlled using the operation parameters.

  However, based on the external environment information, when it is determined that the operation of the elevator is the operation control by the operation parameter in the special setting, and the operation parameter setting is determined not to be the special setting, the operation control by the special setting is changed to the standard setting. Change to operation control based on operation parameters.

  As described above, the parameter setting unit 7 determines the optimum operation parameter based on the external environment information, and the group management control unit 6 executes the operation based on the operation parameter, whereby the group management according to the present embodiment is performed. The control system can perform appropriate operation control according to the external environment.

  That is, in this embodiment, when the temperature and humidity are high, the setting of the car load value and the door opening restraint time on the reference floor is changed from the operation parameter shown in FIG. 3 (a) to the operation parameter shown in FIG. 3 (b). By changing, the convenience of the user can be improved. In other words, when the temperature and humidity are high, the relationship between the load setting value and the door opening restraint time is reset so that users in the car can start immediately even if there are fewer passengers than the rated number. Become. Thereby, the service time of the user in the car can be shortened, or the car rounding time can be shortened. In addition, the waiting time of the hall user can be shortened.

(Second Embodiment)
Next, a second embodiment will be described.

  FIG. 8 is a block diagram showing the configuration of the group management control system according to the second embodiment of the present invention. FIG. 9 is a flowchart showing the control of the group management control system according to the second embodiment of the present invention. FIG. 10 is a diagram showing an example of a storage format in the database unit according to the second embodiment of the present invention. FIG. 11 is a flowchart showing processing in the learning unit according to the second embodiment of the present invention. As shown in FIG. 8, the present embodiment further includes a database unit 8 and a learning unit 9 in the group management control device 3 according to the first embodiment.

  This embodiment determines whether or not the elevator operation control by the operation parameters set by the parameter setting unit 7 according to the first embodiment described above using the external environment information is appropriate, and determines that it is not appropriate. In such a case, the purpose is to return the operation parameter to an existing set value that is determined in advance. Another object of the present invention is to change the parameters in the membership function to appropriate ones by learning so that the operation parameters in special settings are used appropriately. That is, the operation parameter is changed from the special setting to the standard setting in the first embodiment described above, or the parameter in the membership function is changed by learning.

  The database unit 8 is connected to the group management control unit 6 and the parameter setting unit 7, and when the parameter setting unit 7 determines an operation parameter according to the state of the external environment and transmits it to the group management control unit 6, the external environment The situation and the allocated service performance based on the transmitted operation parameter are stored in association with each other. For example, when the operation control by one operation parameter according to the external environment condition is performed under an external environment condition of a certain temperature and humidity, the allocated service performance by the operation control is stored. Allocated service performance refers to service performance such as passenger waiting time and boarding time.

  The learning unit 9 uses the assigned service performance based on the operation parameter corresponding to the external environment stored in the database unit 8 and the operation parameter used as default data when the operation is not performed based on the operation parameter corresponding to the external environment. Compare the performance of the assigned services. As a result of comparison, when the operation with the operation parameter according to the external environment is worse than the operation with the normal operation parameter, the service parameter determination method according to the external environment determined by the parameter setting unit 7 To correct. Details of the method for correcting the operation parameter determination method will be described later.

  That is, the learning unit 9 newly provided in the group management control device 3 sets the parameter setting value set in the parameter setting unit 7 when a situation in which the parameter setting by the parameter setting unit 7 is determined to be inappropriate continues. It is intended to be corrected. Hereinafter, a specific description will be given with reference to the flowchart of FIG.

  The flowchart shown in FIG. 9 shows performance evaluation of operation control using operation parameters set using external environment information and storage of evaluation data. This process is executed every certain time, for example, every 5 minutes.

  First, the group management control unit 6 determines whether or not the setting value of the operation parameter in the operation control currently being performed is due to the special setting (S1). When it is determined that the operation control based on the operation parameter in the special setting is not performed (NO in S1), the operation control based on the operation parameter in the standard setting is continued. When it is determined that the set value of the operation parameter is due to the special setting (YES in S1), the group management control unit 6 calculates the service performance of the operation control based on the operation parameter in the special setting (S2). The service performance calculation method is not particularly limited, but is calculated based on service time, non-response time, and the like. Since this process is executed at regular time intervals, the service performance is also calculated at an average value for a fixed time period, here 5 minutes.

  After calculating the service performance, the group management control unit 6 determines whether or not the service performance has been improved by operation control based on operation parameters set using external environment information, that is, operation control based on special settings (S3). The service performance improvement determination is performed by comparing the service performance of the operation control by special setting and the operation control by the parameter setting value set in the parameter setting unit 7 in advance, that is, the service performance of the operation control by standard setting. .

  The service performance of the operation control by the standard setting is periodically calculated when the operation control by the special setting is not performed, and the calculation results are stored in the database unit 8 in time series order. And the service performance of the operation control by the standard setting memorize | stored in the database part 8 is referred in order to compare with the service performance of the operation control by the special setting as needed. As a result of comparing the two service performances, the improvement degree of the service performance is determined in three stages of ○, Δ, and ×.

  Here, a procedure for determining the improvement degree of the service performance in three stages of ◯, Δ, and X will be described.

As a result of comparing the service performance of operation control with standard settings stored in the database unit 8 in advance with the service performance of operation control with special settings, it is determined that the service performance of operation control with special settings is good (time system Therefore, it is determined that there is an effect of improving service performance. In such a case, service performance (improvement of service time and non-response time) for the user is improved by performing operation control using external environment information. (Improvement level)
If the service performance is improved (YES in S3), the external environment information acquired by the parameter setting unit 7 in the database unit 8 and the degree of service improvement are assumed to be effective in improving the service by performing operation control with special settings. The information of ○ is transmitted (S4).

  On the other hand, as a result of comparing the service performance of the operation control by the standard setting stored in the database unit 8 in advance with the service performance of the operation control by the special setting, it is not determined that the operation service performance by the special setting is good ( (NO in S3) (when the value of the service performance by the special setting is not small), the learning unit 9 determines whether or not the operation service performance by the special setting is deteriorated (S5). The determination of the deterioration of the operation service performance is made based on whether or not the difference between the service performance value of the operation control by the special setting and the service performance value of the operation control by the standard setting is equal to or greater than a predetermined value α.

  The predetermined value α indicates an allowable amount of so-called performance deterioration, and is a fixed value set in advance in the learning unit 9 or the like. If the difference between the service performance of the operation control by the special setting set by the parameter setting unit 7 based on the external environment information and the value of the service performance of the operation control by the standard setting is less than the predetermined value α, the parameter It is determined that the deterioration of the service performance of the operation control due to the special setting set by the setting unit 7 based on the external environment information is within the error range.

  When it is determined that it is within the error range (NO in S5), the parameter setting unit 7 acquires the database unit 8 as a service improvement level that cannot be said to have deteriorated by performing operation control with special settings. The external environment information and the service improvement degree Δ information are transmitted (S6).

  On the other hand, when the difference between the service performance of the operation control by the special setting set by the parameter setting unit 7 based on the external environment information and the value of the service performance of the operation control by the standard setting is equal to or greater than the predetermined value α. Then, it is determined that the service performance of the operation control by the special setting set by the parameter setting unit 7 based on the external environment information exceeds the allowable deterioration amount.

  When it is determined that the service performance of the operation control by special setting exceeds the allowable deterioration (YES in S5), the database unit 8 determines that the service improvement degree is deteriorated by performing the operation control by special setting. The external environment information and service improvement degree x information acquired by the parameter setting unit 7 is transmitted (S7).

  In such a case, the parameter setting unit 7 discards the operation parameter in the special setting (S8), assuming that there is a problem in the parameter setting itself, not the influence due to the usage situation of the user, and the parameter setting unit 7 in advance. The operation control is performed using the operation parameter according to the standard setting set in (S9). As a result, the operation control by the special setting in which the service performance is deteriorated is canceled and the service performance is improved.

  Further, it is assumed that the service performance improvement is not expected with the operation parameter in the special setting set by the parameter setting unit 7 based on the external environment information, and the external environment information and the service performance improvement acquired by the parameter setting unit 7 in the database unit 8 Send information that is not expected.

  As described above, whether the operation parameter in the special setting set by the parameter setting unit 7 based on the external environment information by the parameter determination performance determination using the external environment information shown in the flowchart of FIG. 9 has a service performance improvement effect. It is determined whether or not, and the determination result is stored in the database unit 8. The database unit 8 is stored in a format as shown in FIG. 10, and external environment information (in this embodiment, temperature / humidity), time data, and service improvement information at the time of measurement are stored in association with each other.

  The learning unit 9 in the group management control device 3 performs learning based on the aforementioned data stored in the database unit 8 and adjusts the parameters in the membership function stored in the parameter setting unit 7. This will be specifically described below with reference to the flowchart shown in FIG.

  First, from the membership function currently used, the threshold value that is a criterion for determining whether or not the parameter setting unit 7 performs the operation control in the special setting set based on the external environment information, that is, in the standard setting The temperature / humidity threshold value, which is a reference for determining that the operation control in the special setting is to be performed from the operation control, is calculated (S1). In the present embodiment, it is calculated from the above-described membership function that the temperature threshold is 25 ° C. and the humidity threshold is 50%.

  Next, it is determined whether each calculated threshold value is optimal for the current elevator operation. When it is determined to be optimal, elevator operation control is performed without changing the threshold value. On the other hand, when it is determined that it is not optimal, the threshold value is appropriately changed to optimize the membership function. Correct it. Hereinafter, a specific determination method regarding the membership function for temperature will be described.

  First, the learning unit 9 calculates the service performance deterioration rate within the vicinity of the current threshold (25 ° C.) for the external environment information stored in the database unit 8 and the service improvement result associated with the external environment information ( S2). Here, the neighborhood range is, for example, a range of ± 2 ° C. with the current threshold as a boundary, and the learning unit 9 acquires a service improvement result within this range.

  The service performance deterioration rate is divided into two with the current threshold as a boundary, and the number of improvements x of the total number of measurements in each range is calculated, and the degree of improvement x of the total number of measurements in the range x The service performance deterioration rate can be calculated by calculating the ratio. Then, based on the service deterioration rate, it is determined whether or not to modify the membership function (S3). At this time, if there is no significant difference in the service performance deterioration rate in each range (NO in S3), for example, if the difference is within 5%, there is no problem in the membership function currently used, and parameter setting The processing is terminated on the assumption that the unit 7 has properly determined the external environment information and the learning unit 9 does not need to modify the membership function.

  On the other hand, when the learning unit 9 determines that the membership function needs to be corrected (YES in S3), an appropriate threshold value is calculated and changed from the conventional threshold value to the corrected threshold value (S4). Then, the membership function is corrected (S5).

Here, as shown in FIG. 12, it is assumed that the service performance deterioration rate a ₁ = 50% in the range of 23 to 25 ° C. and the service performance deterioration rate a ₂ in the range of 25 to 27 ° C. = 10%.

The threshold value changing direction is assumed to move to the lower service performance deterioration rate described above, and the corrected threshold value x ′ is expressed by Equation 3 below.

In the above formula, a ₁ and a ₂ indicate the service performance deterioration rate in each range, b indicates a division range based on the threshold, and x indicates a threshold before correction. In this embodiment, since a ₁ = 0.5, a ₂ = 0.1, b = 2, and x = 25, the respective values are substituted into the above Equation 3. As a result, x ′ = 25.4 ° C.

  After the corrected threshold value x ′ is calculated, the learning unit 9 changes the membership function shown in the above equations 1 and 2.

In the present embodiment, in order to change the membership functions to be simplified, and intended to correct T ₀ which is one of the set value. The corrected T ₀ is determined by the following equation, for example.

  The above Equation 4 is a function that can be derived by using the functions shown in Equation 1 and Equation 2. That is, Equation 4 is derived as Equation 1 = Equation 2 and t = x ′ = 25.4.

From Equation 4, T ₀ ≈21.5, and by substituting this value into Equation 1 and Equation 2, the process of changing the membership function for determining the external environment information is completed. When the membership function has been changed, the learning unit 9 transmits the changed membership function to the parameter setting unit 7 (S6). This process is corrected for each threshold value that is set. That is, in the present embodiment, a threshold value correction process for humidity is performed in addition to temperature.

  Moreover, the said process is performed regularly and correction is repeated until an appropriate threshold value is determined by learning by the learning unit 9. If the correction processing is not performed regularly, the reason why the appropriate threshold value is not determined is that, as shown in FIG. This is because even if it is necessary to change the value, only one division range (= b) based on the threshold value is changed in one process. However, since the threshold value itself is changed by repeatedly executing the process, the threshold value gradually approaches the appropriate threshold value, and finally the appropriate threshold value is determined.

  As described above, according to the present embodiment, the service improvement degree is determined when the operation control is performed using the operation parameter in the special setting set by the parameter setting unit 7 based on the external environment information, and the operation control based on the special setting is performed. If the service performance has deteriorated as a result of performing the operation, the operation parameter by special setting is discarded, and the operation control by the standard setting stored in the database unit 8 in advance is performed, thereby affecting the influence of the service performance deterioration. Can be minimized.

  Further, the external environment information and the service improvement information at that time when the operation control in the special setting is performed are stored in the database unit 8 and used for learning, so that the parameters of the membership function used in the parameter setting unit 7 can be set. Can be adjusted. Accordingly, the parameter setting unit 7 can perform operation control using parameters suitable for the acquired external environment information.
