Description

  The present invention relates to an environmental equipment control system that controls environmental equipment such as air conditioning equipment.

  In controlling environmental equipment such as air conditioning equipment installed in buildings, social demands for energy conservation due to global warming are increasing. In particular, the newly introduced Energy Saving Law requires the optimization of energy management using BEMS <Trademark of Energy Saving Center> and the like. However, in terms of the actual situation of building management, building managers have not always properly operated and managed environmental equipment from the viewpoint of comfort and energy saving. Especially for thermal management of living spaces where energy saving and comfort are intricately related, conventional set temperature (control target value) is used blindly for ease of management, and from residents (hereinafter referred to as users). It was common to change the set temperature according to the claim.

  In other words, because the thermal management is performed without fully considering the characteristics of the building and the user, the living space is not necessarily maintained in a state that the user feels comfortable, and there is a possibility that energy for operating the air conditioning equipment will be wasted. was there. In addition, the user is present in a thermal environment managed by the building manager, and it is considered that there is a considerable dissatisfaction with the inability to control the user's own environment.

  In response to such problems caused by thermal management, users' requests for thermal environment are collected in real time from various communication devices (hereinafter referred to as personal terminals) such as personal personal computer terminals, and the collected results are collected. The set temperature is determined based on this, and the user's desired thermal environment and the set temperature are correlated in real time, and the user characteristics that change from moment to moment and the building characteristics such as the temperature sensor detection value and the temperature difference in the living area There has been proposed a system that can control the thermal environment according to the above (for example, Patent Document 1).

  In the system disclosed in Patent Document 1, the control logic is configured on the assumption that the user is periodically prompted to request the environment and the environment request information can be collected.

  In addition, the present inventors have also proposed an environmental equipment control system in which an optimum environmental setting value of comfort and energy is determined by using a user's request for the environment.

JP 2004-205202 A (paragraph numbers 0067 to 0075)

  By the way, even in the case of a system using the above-mentioned environment requirements, there are the following disadvantages.

  In other words, for example, consider an area where air conditioning equipment is installed. As shown in FIG. 9A, the outlets A1, A2 and A3 arranged on the ceiling work normally, and the set temperature is set to 26 ° C., for example. If it is, the room temperature immediately below any of the outlets A1 to A3 is also maintained at 26 ° C. However, if the central outlet A2 fails for some reason, for example, the room temperature below the outlet A2 rises to 28 ° C., for example, as shown in FIG. 9B. Therefore, the person M2 directly under the outlet A2 feels hot and therefore makes a request for lowering the temperature. When this request is accepted and the set temperature is lowered to 24 ° C., the room temperature immediately below the malfunctioning outlet A2 is 26 ° C. as shown in FIG. 9C, but the normal outlet A1, The room temperature immediately below A3 is 24 ° C. as set, and people M1 and M3 feel cold under these air outlets A1 and A3. Therefore, a request to raise the temperature is made, so if one request is put in, the other causes inconvenience, and the request to eliminate this inconvenience is issued from the other, and the request is issued alternately. As a result, the frequency of requests increases and the system becomes unstable.

  The present invention has been made in view of the above-mentioned points, and the object is to determine that there is an abnormality when the frequency of reporting requests for the air-conditioning environment increases due to defects in the air-conditioning equipment, etc. It is to provide an environmental equipment control system capable of

  Embodiments of the present invention will be described below.

(Embodiment 1)
FIG. 2A shows a plan view of an example of an area in a building where the system of the present embodiment is installed. In this example, the area is divided into an east area EA and a west area WE. The environment is controlled by air-conditioning equipment installed in the machine room I, and in order to eliminate the uneven distribution of the thermal load existing in the air-conditioning target area and maintain a uniform thermal environment, a variable air volume method is adopted for the blowing. The thermal environment of the perimeter unit is controlled by air conditioning equipment such as an FCU (Fan Coil Unit).

  In this embodiment, a personal terminal 1 used by a person in the area is connected to a local network (hereinafter referred to as an in-house LAN) 2 as shown in FIG. 2B, and also connected to the Internet. In FIG. 2A, II indicates a conference room, III indicates a toilet, IV indicates an elevator hall, and V indicates a staircase.

  In the environmental equipment control system of this embodiment, as shown in FIG. 2B, the environmental control server 3 as the main device is connected to the above-mentioned personal terminal 1 through the in-house LAN 2, and each use from the personal terminal 1 is performed. The environmental request information sent by the person is collected, a control plan is determined based on the collected environmental request information, and the determined control plan is determined from the building equipment control communication line 4, the air conditioning subsystem (air conditioning Icont). 5. It has a function of reflecting through the local controller 6 to the control of the air conditioning equipment 7 as environmental equipment.

  FIG. 1 shows a functional configuration diagram of a computer system constituting the environment control server 3, and main means configured as functions are an environment information acquisition means 30 and presence information acquisition means constituting request information acquisition means. 34, equipment control plan setting means 31, area environment information acquisition means 32, equipment control means 33, and environmental abnormality judgment means 35, and comprises a main memory unit (not shown) and an external storage device (not shown). As a means for data storage and database storage.

  The environment information acquisition means 30 collects environmental requests (environment request information) to be transmitted to the environment control server 3 using dedicated software installed on the personal terminal 1 used by the user. Then, a process of writing to the environment information file Da in a predetermined area of the built-in main memory unit (not shown) is performed. As for information transmitted from the personal terminal 1 of the user through the in-house LAN 2, which user transmitted from which IP address of the personal terminal 1 is transmitted to which position in the area is stored in the external storage device. It is specified based on the stored personal information, the IP address, and the arrangement information of the personal terminal 1 associated with the IP address, and is associated with the above-described environmental request information in the environmental information file Da. Remembered.

  The presence information acquisition means 34 is assumed that the personal terminal 1 is given to everyone who enjoys the environment, and the IP address of each personal terminal 1 and the user and the use position on the floor in the area. If the IP address is received together with the activation information when each personal terminal 1 is activated, the personal information and the use position registered in the external storage device in advance in association with the IP address are stored. A process of reading from the file Dc, specifying who and where information is transmitted, and writing the specified result to the presence information file Dc as presence information is performed.

  In addition, it periodically inquires each personal terminal 1 via the in-house LAN 2 and writes the number of personal terminals 1 that have responses (≈ the number of attendees) in the presence information file Dc. The presence or absence and the total number of seats may be grasped.

  Accordingly, the presence information acquisition means 34 and the environment information acquisition means 30 fulfill the function of the request information acquisition means.

  The equipment control plan setting means 31 reads out the environment information file Da stored in the main memory unit and the judgment standard file Db in which the judgment standard rule as the control rule is written, and extracts information necessary for determining the control plan. Both the analysis information acquisition function to be performed and the ratio (hereinafter referred to as the request ratio) of the total number of users (referred to the presence information file Dc) of two environmental request information conflicting with the information obtained by the analysis information acquisition function. It corresponds to a control plan for controlling the air conditioning equipment 7 via the equipment control means 33 from the ratio of the demand rate obtained by the statistical information computation function and the percentage of the demand rate obtained by the statistical information computation function. And a function of setting the set temperature (control target value) and a function of outputting the set temperature as a control history file Dd to the external storage device. There.

  The area environment information acquisition means 32 is for acquiring the number of people in the area to be controlled (total number of users), the detection temperature of a temperature sensor (not shown) for detecting the outside temperature and room temperature, and the like. Yes, the total number of attendees (users) is obtained from the attendance information file Dc storing the information obtained by the attendance information obtaining means 34.

  The equipment control means 33 acquires the latest control history stored in the control history file Dd by polling, and based on the contents, the air conditioning equipment 7 that is a thermal environment equipment is connected to the communication line 4, the air conditioning subsystem 5, and the local Control data to be controlled through the controller 6 is generated.

  A communication format in which the equipment control means 33 exchanges control data with the air conditioning subsystem 5 via the communication line 4 may be any known format, and is not particularly limited, and thus description thereof is omitted here. . Similarly, the air-conditioning subsystem 5 controls the air-conditioning equipment 7 through the local controller 6 as long as it uses a well-known format and is not particularly limited.

  The environmental abnormality determination means 35 determines that the environment is in an abnormal state when the frequency of reporting environmental requests from the personal terminal 1 satisfies the abnormality determination condition. A function for notifying the occurrence of an abnormality is provided from the notification means 8 provided in the above.

  When the dedicated software is launched, the personal terminal 1 displays a standby screen on which a taskbar and an icon (not shown) resident on the taskbar are displayed on the monitor screen. By clicking a predetermined icon, the input window of this system can be opened.

  The functions of each icon displayed here include a window for inputting a request for the air conditioning environment (environment information of the user), a window for displaying various sensory information, and feedback of information on the current situation to the user ( It is assumed that it has a function of opening a window for feedback information).

  As shown in FIG. 3, the window for inputting environmental information for acquiring a request for the personal environment of the present embodiment is “I want you to raise the temperature”, “I want you to lower the temperature”, and “Neither”. An input section for “request” having check columns C1, C2, and C3 that can be selected from three options is provided. By checking any one of these check columns C1 to C3, the user can indicate an environment related to the air conditioning environment. The request information can be sent to the environment control server 3. That is, the environment information is uploaded to the environment control server 3 as a specific user request at the time of the check. In addition, a comment input field CM is also provided so that a user's comment can also be entered. Since a request check and comment input can be performed in the same input window, it is easy to input.

  In actual operation, as described above, it is necessary to ask in detail how the user feels in order to analyze the state in more detail, as well as when it is appropriate for the user to raise the request arbitrarily. . In addition to the “request” described above, the input window in FIG. 3 collects information such as how to feel the temperature sensation (“warmth / warmth”) that is important for environmental adjustment and the comfort (“comfort”) that accompanies it. Check columns C10 to C16 and C20 to C26 are provided.

  Such information also has the location information of the caller (user) at the same time. For example, the position and direction of the balloon are appropriate for the individual as information on how they feel, even if they do not make a request. It is very useful for the purpose of performing detailed environmental analysis. Building managers can make adjustments based on this information.

  Here, when a dedicated personal terminal 1 is given to all users, the IP address of the user's personal terminal 1 and the user and their use on the floor are separately used as information for identifying individual users. The location information is used as a table. In the input window shown in FIG. 3, the IP address of the terminal 1 is displayed on the side of the button BT for closing the window at the center bottom.

  In addition, when the dedicated software is started up in each personal terminal 1, activation of each personal terminal 1 is notified to the environment control server 3 by a signal. Based on the confirmed signal, the acquisition unit 34 identifies who and where the information is transmitted, and performs the process of registering it in the presence information file Dc as presence information as described above. Each time the request information is transmitted from the personal terminal 1, when the environmental information acquisition unit 30 recognizes which personal terminal 1 is transmitted by the IP address, the environmental information acquisition unit 30 stores the information as described above. As described above, it is stored in the main memory unit and the external storage device.

  Next, the analysis information acquisition function, statistical information calculation function, equipment control determination function, and environmental abnormality determination means 35 of the equipment control plan setting means 31 will be described with reference to the flowchart of FIG.

  First, when the user voluntarily declares the environmental request information using the personal terminal 1, the agreement formation application is started (step S 1), and the environmental control server 3 receives the environmental request information acquired through the environmental information acquisition means 30. Write to the environment information file Da. That is, environmental request information is collected (step S2). The environmental request information acquired and written in the environmental information file Da is held for, for example, one hour from the time of reporting, and is reset after one hour has passed, and is in a non-declared state.

  In the analysis information acquisition function, the following processing is performed in order to use the collected environmental request information for determining the equipment control content (control plan). In other words, if there is no change in the content of the environmental request information, it will be handled until the user's declaration is changed or reset as a one-minute declaration, and a new one will be issued after the reset. Until there is a declaration, it is converted into information that is not declared and written to the analysis file. That is, information effective for control is extracted (step S3).

  Using the analysis information written in the analysis file, the statistical information calculation function calculates the request rate for the total number of users of conflicting environmental request information of “I want to raise the temperature” and “I want to lower the temperature”, Processing for obtaining the ratio of the request rate is performed.

  In this way, the statistical information calculation function is based on the information obtained by converting the environmental request information reported every minute by the analysis information acquisition function for analysis. And the process which calculates | requires the ratio is performed. Based on this ratio, the facility control decision function performs decision (setting) of the control plan in step S4 as will be described later.

  In the facility control determination function, the request rate “I want to increase the temperature” and the request rate “I want to decrease the temperature” obtained by the statistical information calculation function as described above are taken in, and the area environment information acquisition means 32 Capture the number of people (total number of users) in the target area that is being acquired. On the other hand, the judgment standard value is set by taking the judgment standard rule information of the judgment standard file Db.

  In the present embodiment, the determination criterion rule is read from the determination criterion file Db for each operation condition (cooling or heating) of the air conditioning equipment 7. Here, as a criterion rule for determining the equipment control content (control plan), there are “comfort priority control” shown in FIG. 5A and “energy saving priority control” shown in FIG. Whether to select one of these is set in advance based on an operation judgment by the building manager.

  For example, in the “comfort priority control” decision criterion rule, the vertical axis is the request rate for “I want to raise the temperature”, and the horizontal axis is the request rate for “I want to lower the temperature”. The line connecting the points, the line connecting the 0 points from the point where "I want to increase the temperature" is 65% and "I want to decrease the temperature" is 35%, and the vertical axis where "I want to decrease the temperature" is surrounded by 0% Set the temperature increase range to “▲”, and connect the points where both desired rates are 100%, “I want to increase the temperature” to 35%, and “I want to decrease the temperature” from 65% to 0 points. The area surrounded by the connecting line and the horizontal axis where “I want to increase the temperature” is 0% is the set temperature decrease area “▼”. The set temperature increase area “▲” and the set temperature decrease area “▼” The sandwiched area is set as the set temperature maintenance area “■”. However, if the number of declarations is small, it is assumed that the user is not dissatisfied with the environment, and the area where the request rate is 10% or less for both the number of attendees is also set as the set temperature maintenance area “□”. Yes.

  On the other hand, in the criterion rule of “energy saving priority control”, a line connecting both points where the request rate is 100%, a line connecting both the points where the request rate is 50% and both points where the request rate is 5% and “temperature” ”I want to lower” is the area surrounded by the vertical axis of 0% and “I want to lower the temperature” is the area where the request rate is 5% or less. Connected line, 20% request rate for "I want to raise temperature", 80% request rate for "I want to lower temperature", 5% request rate for "I want to raise temperature", "I want to lower temperature" request The area surrounded by the line connecting the point where the rate is 20% and the horizontal axis where the desired rate is 0% is the set temperature drop area “▼”, and these set temperature rise areas “▲” And the set temperature drop area “▼” is set as the set temperature maintaining area “■”. A feature of this criterion rule is that the set temperature is automatically raised when the request rate of “I want to lower the temperature” is 5% or less.

  Therefore, in step S4, the position determined by the ratio of each request rate obtained by the statistical information calculation function is plotted on the determination reference rule to perform the area determination process, and the set temperature maintenance area “■” (or □) is determined. Based on (determination of set temperature decrease region “▼”, determination of set temperature increase region “▲”), temperature ΔT to be changed with respect to the current set temperature is determined. Then, the set temperature at the previous determination is acquired from the control history file Dd, and a new set temperature is obtained from ΔT determined as described above and the acquired set temperature, and is written in the control history file Dd.

  Then, the facility control means 33 that has acquired the latest set temperature written in the control history file Dd by polling generates control data for applying this set temperature to the air conditioning equipment 7 and sends the air conditioning equipment 7 to the air conditioning subsystem, Control is performed through the local controller to decrease, increase or maintain the set temperature of the environment (step S5). Thereafter, the processing from step S2 to step S5 is repeated until the end time of environmental control is determined in step S6.

  Now, when it is time to schedule the environmental control, the environmental abnormality determination means 35 operates to extract the environmental request information of the day from the environmental information file Da, process it, and perform the processing after step S10.

  It is assumed that the environment control server 3 of this embodiment has the following report acceptance rule.

  That is, processing for not accepting the user's signal is performed for a certain time (for example, 5 minutes) after the personal terminal 1 is started up. This is because the psychophysiology of the user is in an unsteady state, and it is considered that the objectivity with respect to the information on the environment is lost.

  Further, if a certain time (for example, 3 minutes) has not passed since the previous report, a process for not accepting the next report is performed. This is because, when the environmental abnormality determination means 35 determines an environmental abnormality based on the reporting frequency, even a short time continuous reporting may be erroneously determined as an environmental abnormality.

  Here, the east area EA shown in FIG. 2 is divided into zones EA1 to EA3 as shown in FIG. 6A, and the users of the zones EA1 to EA3 are shown in FIGS. , F, G to I, for example, the states and reporting states of the personal terminals 1 of the users A to D in the zone EA1 in a certain time zone 9: 0 to 9:08 (FIG. 7A). ) Is used as an example to explain environmental abnormality determination. In FIG. 7A, the personal terminal 1 of the user A is started at 9:03, and a request for lowering the set temperature (DOWN) is made at 9:03 and 9:05. It is not accepted according to the rules of the environment control server 3 described above. User B has made a request to lower the temperature (DOWN) between 9:01 and 9:03 three times, but this report is not accepted according to the rules of the environmental control server 3 described above.

  On the other hand, a user who has returned from the outside and is not accustomed to the environment frequently submits a request report. If an abnormality is determined based on the request report, a false report is generated. Therefore, misinformation is avoided by handling only the request information after having been present for a predetermined time as a report. The environmental abnormality determination means 35 performs information removal processing that becomes noise during the determination processing based on the environmental information and presence information. That is, in the request declaration content of FIG. 7A corresponding to the control, the request declaration at the time of rising of the personal terminal 1 (in the case of the user A, (DOWN) at time 9:03 or 9:05 is reflected in the control). However, the abnormality determination does not use the request declaration until a certain time (for example, 5 minutes) from the rise of the personal terminal 1. FIG.7 (b) is "1" for the declaration adopted at the time of the abnormality determination. In addition, a non-recruitment report, that is, a report regarded as noise is indicated with “0.” Note that OFF indicates the off state of the personal terminal 1.

  In this way, the information removal process that causes noise is performed, and the reporting frequency of each person is obtained. At the same time, the effective attendance ratio of each person is obtained from the ratio of the on-time of the personal terminal 1 to the working hours, and the reporting frequency is corrected based on the effective attendance ratio.

  Table 1 shows the reporting frequency and the effective attendance rate of users A to D on a certain day after information removal processing that causes noise. Table 2 shows an example of the report frequency after correction of the users A to G.

  A user with a low effective attendance rate (for example, 10% or less) is excluded from an abnormality determination target.

  After the above correction process, the average reporting frequency is calculated for each target zone for environmental control. In addition, when there are extremely many reports of the user G like zone EA3 of FIG.6 (b), this is considered to be an individual characteristic. Therefore, users who have extremely high reporting frequency in the zone are excluded using a statistical method. For example, the average reporting frequency for users G, H, and I who perform processing that omits values greater than (average reporting frequency + standard deviation) in the zone is 15.7 times / day, because the standard deviation is 15 times / day. The user G with 33 times of reporting frequency is omitted.

  As a result of the above calculation, the average reporting frequency of the zone EA1 is 7 times / day, the zone EA2 is 27.5 times / day, and the zone EA3 is 7 times / day by excluding the user G.

  As described above, processing for removing information that causes noise, correction, and calculation of the average reporting frequency is performed (step S10), and then a determination criterion is statistically calculated from the value of the average reporting frequency between zones, and the calculated determination Detect zones with a high average reporting frequency that exceed the standard. For example, the abnormality determination standard is determined to be 24.0 times / day from the value of the average reporting frequency of zone EA1 to zone EA3 in FIG. 6 (a) 13.2 times / day + standard deviation 10.8. It is determined that there is an environmental abnormality in the zone 2 that exceeds the abnormality determination criterion, and the determination result is notified from the notification means 4 based on this determination result to notify the building manager that an environmental abnormality has occurred.

  As described above, according to the present embodiment, it is possible to detect environmental anomalies by comparing the frequency of reporting the user's request for the environment with a certain criterion, and further, the environmental request information can be found in other zones. Compared to the environmental request information, it is possible to reliably detect environmental anomalies. In particular, when calculating the average value of the reporting frequency in the zone, a special feeling of warmth and cooling can be achieved by omitting extremely frequent requests. It is possible to avoid misjudgment under the influence of users. Further, by limiting to only the request information after having been present for a predetermined time, an abnormality determination is made based on the request information of a user who is not used to the environment, and misinformation is avoided.

(Embodiment 2)
In the first embodiment, the abnormality determination standard is determined every day, but this embodiment is characterized in that it is determined based on the past reporting frequency and the relationship between the past reporting frequency and the indoor set temperature. Since the hardware configuration is the same as that of the first embodiment, illustration and description are omitted here.

  For example, as shown in FIG. 8, it is assumed that there is a relationship between the set room temperature and the average reporting frequency, and the abnormality determination criterion a is obtained from the average value and standard deviation of past reporting frequencies. In the figure, b indicates an environmental abnormality range exceeding the abnormality determination standard a.

  For example, in the above-mentioned zone EA1, for example, when the average reporting frequency of each day for a certain four days is 7 times / 1 day, 5 times / day, 8 times / 1 day, 25 times / day, the past 4 days The average value of the reporting frequency is 10.8 times / day, and its standard deviation is 8.2 times / day. Therefore, as described above, when the abnormality judgment standard is determined from the average reporting frequency + standard judgment standard, it is 19 times / day, and it can be judged that there has been an environmental abnormality on the last day of the past four days by this abnormality judgment standard.

  Thus, in the present embodiment, by using the above-described configuration, for example, an air conditioning facility in which the control target value changes frequently every moment in response to a signal from the human sensor system, the desired report frequency affects the control target value. Even in the receiving system, it is possible to accurately determine the abnormality by eliminating the influence of the control target value by changing the abnormality determination standard according to the set temperature and the frequency of reporting the past request information.

(Embodiment 3)
In the above-described embodiment, the abnormality determination is performed based on the request frequency of “I want you to raise the temperature” or “I want you to lower it”. However, there are cases where the environmental abnormality determination means 35 makes an abnormality determination even though the abnormality does not feel much abnormality with respect to the environment. Therefore, in this embodiment, when you want to raise the temperature, determine the degree of request for “I want you to raise the temperature” or “I want you to lower” from the declaration information about “Comfort”. There is a feature in the point which was made to perform.

  In other words, an abnormality is determined by detecting the above-mentioned problem, for example, by determining the degree of request of “I want you to lower the temperature” or “I want you to lower” from the declaration information on “Comfort” in the input window of FIG. I do.

  In this case, for example, weighting as shown in Table 3 is performed.

  Here, if the weight of each item is W and the number of people is X, the degree Y of the environmental improvement request can be calculated as follows.

Y = Σ (W × X)
Thus, when the value of Y exceeds a predetermined threshold, it can be determined that there is an abnormality.

  As described above, in the present embodiment, since human sense information is used in addition to the reporting frequency, it is possible to determine whether it is comfortable or uncomfortable, and therefore it is possible to accurately determine an environmental abnormality.

(Embodiment 4)
In the present embodiment, for example, a column for inputting an arbitrary phrase (for example, a comment input column CM) is provided in the input window shown in FIG. 3, and various data mining such as text mining is performed on the phrase input to the comment column CM. It is characterized in that the environmental abnormality determination means 35 has a function of using and detecting abnormal equipment. Further, in the present embodiment, abnormal expression information that associates words and phrases that are likely to be used when expressing an abnormal state correspondingly, an abnormal state expression, and an abnormal state corresponding thereto is stored in an external storage device (not shown) as a database. Register.

  In addition, since the structure for performing the abnormality determination by report frequency may be any structure of Embodiment 1-3, it abbreviate | omits about a structure and its determination process here.

  Thus, in this embodiment, when an arbitrary phrase is sent from the personal terminal 1, the environment information acquisition unit 30 stores it in the environment information file Da.

On the other hand, the environmental abnormality determination means 35 reads an arbitrary phrase stored in the environment information file Da during the abnormality determination process. For example, when the arbitrary phrase matches the following logical operation expression, the environmental abnormality determination is performed as described above.
