Definitions
- the present invention relates to link server web-based air-conditioning monitoring systems.
- Air-conditioning monitoring systems for centrally monitoring the operation of air-conditioning machines installed, for example, in buildings are conventionally known.
- the operation and the control of the air-conditioning machines provided in a building are performed by air-conditioning monitoring devices connected to the air-conditioning machines via networks.
- pull-based communication is carried out in such a manner that a client terminal sends a query about monitored items of the air-conditioning machines being monitored at predetermined time intervals to the air-conditioning monitoring devices to acquire data on the ever-changing operating states of those air-conditioning machines.
- the air-conditioning monitoring devices were provided in a distributed manner and pull-based communication was sent from the client terminal to each of the air-conditioning monitoring devices at predetermined time intervals, the client terminal was subjected to a processing load or it took a long time for the client terminal to receive a response to the query from each of the air-conditioning monitoring devices.
- the present invention has been conceived to solve the above-described problems, and an object thereof is to provide an air-conditioning monitoring system that is capable of reducing the load on the client terminal, notifying the client terminal of an event in an air-conditioning machine occurring in an air-conditioning monitoring device not being monitored, and allowing monitoring to be performed with a web browser.
- the present invention employs the following solutions.
- a first aspect according to the present invention is an air-conditioning monitoring system including a client terminal having a web browser; and an air-conditioning monitoring device subordinating a plurality of air-conditioning machines installed in a building to monitor operating states of these air-conditioning machines, wherein a plurality of the air-conditioning monitoring devices are connected via a network, the air-conditioning monitoring devices and the client terminal are connected via the network, and the air-conditioning monitoring devices provide the client terminal with information on the operating states, wherein each of the air-conditioning monitoring devices includes event information collecting means for collecting event information of the air-conditioning machines under control; event detecting means for, if being monitored from the client terminal, detecting and acquiring the event information from the event information collecting means of the other air-conditioning monitoring devices, which are the air-conditioning monitoring devices not being monitored; and first communication means for, if being monitored from the client terminal, sending the event information detected by the event detecting means to the client terminal, wherein the client terminal displays the event information acquired from the first communication means via the browser
- the air-conditioning monitoring device monitors operating states of the air-conditioning machines installed in the building and provides information on the operating states to the client terminal connected via the network.
- events in the air-conditioning machines under control are detected by the event information collecting means to collect event information.
- the event detecting means of an air-conditioning apparatus being monitored by the client terminal collects event information from the event information collecting means of other air-conditioning apparatuses not being monitored connected via the network. Furthermore, the collected event information is sent to the client terminal.
- the event information acquired by the client terminal is displayed via the web browser of the client terminal.
- the event detecting means of the air-conditioning monitoring device being monitored collects event information (e.g., a failure, abnormal non-operation, and recovery from abnormal non-operation of air-conditioning machines) about the air-conditioning machines under control with the other air-conditioning monitoring devices not being monitored and send the collected event information to the client terminal.
- event information e.g., a failure, abnormal non-operation, and recovery from abnormal non-operation of air-conditioning machines
- the client terminal also receives information from the air-conditioning monitoring devices not being monitored, it can be made to look like information is pushed in the client terminal from the other air-conditioning monitoring devices not being monitored.
- the information reported to the client terminal from the air-conditioning monitoring devices not being monitored is event information, the amount of information can be made smaller than when information about operation/non-operation or information about an operating state, such as cooling and heating, of the air-conditioning machines is reported. As a result, not only can the load upon the transmission media through which these data are sent/received be reduced, but the data processing load in the client terminal can be reduced.
- Such event information can be displayed on the client terminal via the web browser.
- freeware such as Internet Explorer (registered trademark)
- events in the air-conditioning machines under control with the air-conditioning monitoring system can be found easily.
- the client terminal of the air-conditioning monitoring system may notify the web browser upon receiving a response result to an acquisition request for the event information sent to the air-conditioning monitoring device, even though display of the web browser is not updated.
- a response result to an acquisition request for event information can be displayed, regardless of whether display update operation of the web browser of the user who uses the client terminal is performed or not.
- the air-conditioning monitoring system may include operating-state-information collecting means for collecting operating state information, which is information on operating states, of the air-conditioning machines under control, wherein the operating state information may be sent to the client terminal via the first communication means in a case of being monitored from the client terminal.
- the operating state information of the air-conditioning machines under control is collected by the operating-state-information collecting means and sent to the client terminal.
- the operating-state-information collecting means can collect operating state information and send it to the client terminal, despite such a delay.
- the times required to collect individual pieces of information or the timings to send them to the client terminal do not depend on each other, allowing independent performance.
- Processing in which the operating-state-information collecting means of the air-conditioning monitoring system collects the operating state information and sends the operating state information to the client terminal may be separated from processing in which the event detecting means collects the event information and sends the event information to the client terminal.
- the processing from collection of the operating state information by the operating-state-information collecting means to sending it to the client terminal is independent of the processing from collection of event information by the event detecting means to sending it to the client terminal, the processing time of the operating-state-information collecting means and the processing time of the event detecting means do not affect each other. For example, even if there is a delay etc. in the network between the air-conditioning monitoring device being monitored and another air-conditioning monitoring device to cause the event detecting means to take a long time in processing, the processing time by the operating-state-information collecting means is not affected. As a result, even in a case where event information cannot be acquired in the client terminal, operating state information can be displayed first, as long as the operating state information has been acquired.
- the client terminal of the air-conditioning monitoring system may notify the display unit of a change in the event information upon acquiring the event information via the first communication means.
- a change in the air-conditioning machines can be checked visually by displaying event information on the screen of the client terminal.
- methods of delivering notifications on the screen include, for example, changing the color of the tab indicating the air-conditioning apparatus including the air-conditioning machine in which an event has taken place, reporting that an event has taken place with a beep sound, and so forth.

- the second screen file 32 that reports event information of each of the air-conditioning monitoring devices is provided separately from the first screen file 31 indicating operating state information, acquisition of event information can be performed concurrently with acquisition of the operating state information of the air-conditioning monitoring device being monitored as separate processing.
- the web browser 42 Upon acquiring the first screen file 31, the web browser 42 analyzes and executes the Java (registered trademark) Script of the first screen file 31 and updates the screen at predetermined time intervals (e.g., 20 seconds) set in the first screen file 31 to acquire operating state information.
- the screen is updated using, for example, the refresh method.
- the web browser 42 analyzes and executes Java (registered trademark) Script of the second screen file 32. More specifically, at predetermined time intervals (e.g., 10 seconds) (the timing may differ from that of screen updating of the first screen file 31), the second screen file 32 queries the other air-conditioning monitoring devices 3b and 3c via the client terminal 2 as to whether an event occurs in the air conditioners 4 under control.
- Fig. 7 shows part of one example of request information sent from the client terminal 2 to the air-conditioning monitoring device 3a in this case.
- a predetermined script (e.g., getstatusofall.php) is read out ((a) in Fig. 7 ) from the application 33 of the air-conditioning monitoring device 3a, for example, by executing the Java (registered trademark) Script of the second screen file 32 at predetermined time intervals ((c) in Fig. 7 ).
- the predetermined script is, for example, a script for detecting event information of the event information collecting sections 12 of other air-conditioning monitoring devices 3b and 3c not being monitored.
- the above-described script is executed by a predetermined function (e.g., getstatus()) in the read-out script ((b) in Fig. 7 ).
- the above-described predetermined script (e.g., getstatusofall.php) is started by the XMLHttpRequest (asynchronous request processing) function, which is an asynchronization read-out function of the AJAX technology, to cause all air-conditioning monitoring devices to sequentially detect the presence of event information.
- the air-conditioning monitoring device 3a After the air-conditioning monitoring device 3a has sent a query to the air-conditioning monitoring device 3b about the presence of an event in the air conditioners 4, the air-conditioning monitoring device 3a proceeds to sending a query about the presence of an event in the air-conditioning monitoring device 3c, even though a response from the air-conditioning monitoring device 3b has not yet arrived and screen transition has not taken place on the client terminal 2.
- the AJAX technology is a known technology, and a detailed description thereof will be omitted.
- a query about the presence of an event in the other air-conditioning monitoring devices 3b and 3c not being monitored becomes possible asynchronously with screen display (screen updating) of the second screen file 32 in the web browser 42.
- screen display screen updating
- the user of the client terminal 2 is relieved of the need to be conscious of the wait time while a query about the presence of an event is in progress.
- a startup request of a predetermined script (getstatusofall.php) that checks for the presence of event information of the other air-conditioning monitoring devices 3b and 3c is acquired from the client terminal 2.
- a predetermined script startup request (getstatusofall.php) is acquired in the air-conditioning monitoring device 3a
- the predetermined script (getstatusofall.php) is started from the application 33.
- connectToURL() as a function for sending the HTTP GET request from the event detecting section 21 to each of the other air-conditioning monitoring devices 3b and 3c, is called from the application 33 ((b) in Fig. 8 ).
- the event detecting section 21 Upon receiving a response from a predetermined file (e.g., recentstatus.php) possessed by another air-conditioning monitoring device 3b or 3c that has received the HTTP GET request, the event detecting section 21 detects event information using this response.
- a predetermined file e.g., recentstatus.php
- the above-described predetermined function (connectToURL()) is communication in PHP on TCP/IP using, for example, the fsock function. By doing so, communication will be made possible because HTTP communication (a port number etc. used in HTTP communication) is permitted in many cases even in a case where a proxy server etc. limiting the port numbers etc. of an application exists on the network between, for example, the air-conditioning monitoring devices.
- the event detecting section 21 of the air-conditioning monitoring device 3a being monitored collects event information about the air conditioners 4 under control with the other air-conditioning monitoring devices 3b and 3c not being monitored and sends the collected event information to the client terminal 2.
- event information of the entire air-conditioning monitoring system 1 can be reliably detected via the event detecting section 21 of the air-conditioning monitoring devices being monitored.
- the amount of information becomes smaller than when information about operation/non-operation or information about an operating state, such as cooling and heating, of the air conditioners 4 is reported.
- the load applied to the network e.g., the Internet
- the load upon data processing of the client terminal 2 can be reduced.
- the content of the event information received by the client terminal 2 can be displayed via the web browser 42.
- freeware such as Internet Explorer (registered trademark)
- an event in the air conditioners 4 under control with the air-conditioning monitoring system can be captured easily.
- the connecting network is not limited to the Internet.
- a network standardized for building management or a LAN (Local Area Network) may be used.
