Description

Technology Field

[0001] The present invention relates to a building integrated control system having a function for providing real-time status information regarding facilities subject to inspection and maintenance. More specifically, the invention relates to a building integrated control system that enables inspection and maintenance work to be performed effectively by allowing not only maintenance experts but also maintenance personnel or on-site facility managers to identify status value information regarding various facilities installed throughout the building in real-time at the work site and perform inspection and maintenance work using only a personal mobile terminal, without the need for wired or wireless internet connections, built-in management programs, or separate support personnel. Background Technology

[0003] In large buildings such as office buildings and apartments, various facilities including HVAC, sanitation, power, lighting, security, fire prevention, and water treatment are complexly installed throughout the building, and various types of building integrated control systems are applied to monitor and control these facilities.

[0004] The building integrated control system consists of a central control unit that comprehensively manages and controls various facilities and systems installed in the building, and a remote control panel that controls the operation of field equipment, collects and analyzes information from field equipment to respond to issues, and transmits the collected and analyzed information to the central control unit.

[0005] While remote control panels control field facilities under the control of a central control unit, Direct Digital Controller (DDC) control panel units are generally applied to enable independent control of field equipment operations. Accordingly, the DDC control panel unit senses or measures various status information of the field and transmits information or data corresponding to request signals from management servers, such as control stations or control PCs of the central control unit.

[0006] The central control unit is a device deployed in a central control room (control room or disaster prevention room) and operated by an integrated management entity; it is equipped with HMI (Human Machine Interface) software to collect various status information from the site, output monitoring results, and perform control and management functions based on input from the manager.

[0007] In a central control room equipped with a central control device, a facility manager is typically stationed to inspect and manage various facilities. When an abnormality occurs, the manager either repairs the relevant equipment directly or requests repairs from maintenance personnel (experts) at the facility company or the integrated control system installation company. To ensure prompt notification of a breakdown, building integrated control systems are being applied in various forms, as disclosed in Registered Patent No. 10-0959099 or Published Patent No. 2011-0017979, which enable a rapid response to breakdowns by notifying the building manager or maintenance expert of the breakdown information via text message to their personal terminals.

[0008] In addition, the inventor's prior registered patent, Registered Patent No. 10-2044883, proposes a building integrated control system that performs an internal error correction function to ensure normal input / output signals are transmitted and received by automatically resetting the equipment through power control when there is an abnormal signal regarding a specific piece of equipment, and notifies an alarm message only when it is determined that there is an abnormality in the equipment by comparing the re-measurement information of the equipment after the equipment reset with the reference value of the equipment. This invention is a useful invention that can resolve basic failures by automatically resetting equipment or sensors on its own and notifies an alarm message only when necessary, thereby reducing the waste of time and manpower caused by unnecessary site visits by facility managers or maintenance personnel from service providers. Prior art literature

[0010] Korean Registered Patent No. 10-0959099 (Registered May 13, 2010) Korean Published Patent No. 2011-0017979 (Published February 23, 2011) Korean Registered Patent No. 10-2044883 (Registered November 8, 2019) The problem to be solved

[0011] As mentioned above, if it is determined that there is an abnormality in the equipment through alarm messages or the like, a facility manager or a maintenance representative from the service provider will move to the installation location of the equipment where the abnormality occurred to resolve the problem and inspect the equipment.

[0012] For the inspection or maintenance of equipment, work is performed by verifying whether various sensors installed in the equipment are functioning properly, whether instrument panel readings or measurements are accurately transmitted to the integrated management system without errors—in other words, whether there are any abnormalities in the signal transmission system for various status values—and how the equipment operates when specific parts are manipulated or replaced. Since the equipment subject to inspection is mostly installed in locations far removed from the central control room, such as machine rooms, pump rooms, and HVAC rooms, support personnel are generally stationed at the DDC control panel unit or the central control room. Workers then carry out inspection and maintenance tasks by verifying the status values ​​of various sensors through these support personnel via telephone or radio.

[0013] However, making wired or wireless calls to ask, answer, and verify specific status values ​​during inspection and maintenance work was extremely cumbersome, and there was a problem in that it was difficult to effectively perform inspection and maintenance work in sites where there was a shortage of managers and it was difficult to assign work assistants.

[0014] On the other hand, there are cases where work is performed by carrying a laptop equipped with a remote control program to the work site and remotely operating the central control system's server to display necessary status values ​​on the central control system's monitor, while verifying them. Although utilizing such a program allows work to be done without separate support personnel, it is difficult to perform inspection and maintenance tasks efficiently because the laptop placed near the work site must be operated frequently. Furthermore, since most field facility managers and maintenance personnel, with the exception of a small number of experts, do not possess terminals equipped with remote control programs or are proficient in operating them, there was a problem in that this method is generally difficult to apply to equipment inspection and maintenance work.

[0015] In addition, when facility managers or maintenance personnel for a specific building are replaced, there was a problem in that it was difficult to quickly inspect or repair the facilities because they were unfamiliar with the building's structure, the location of the facilities, and the locations of inspection points, such as sensors related to the facilities.

[0016] The present invention aims to solve the various problems of conventional building integrated management systems as described above, and provides a building integrated management system that enables efficient inspection and maintenance of facilities by allowing a worker to perform inspection and maintenance work while checking the status information of various facilities installed throughout the building in real time at the work site using only a personal mobile terminal (mobile phone) without a separate wired or wireless internet connection, remote control program, or built-in installation program. means of solving the problem

[0018] A building integrated control system according to the present invention for achieving the above objective comprises: a central control device that manages and controls a plurality of field devices installed in a building, the central control device having a management server having a data storage unit, a processing unit, and a communication unit, an input means for inputting data to the management server, and a display means for displaying data output from the management server; and a direct digital controller (DDC) control panel unit that controls the operation of field devices under the control of the management server, collects and analyzes information of the field devices to respond, and transmits the collected and analyzed information to the central control device.

[0019] The above data storage unit stores a control point database comprising the names of field devices, the names of control points of each field device, and status information of each control point transmitted from the DDC controller; and the processing unit comprises: a transmission target phone number designation module that receives the operator's mobile terminal phone number and stores it in the storage unit; a transmission target control point selection module that receives the control point of the field device to be inspected / maintained and stores it in the storage unit; a transmission target control point status information reading module that reads the names and status information of the control points selected by the transmission target control point selection module from the control point database at preset time intervals; a character data conversion module that converts the names and status information of the control points read by the transmission target control point status information reading module into message character data; and a message transmission module that transmits the message character data to the transmission target phone number through the communication unit at the time intervals.

[0020] According to the building integrated control system of the present invention having such features, a worker can perform inspection and maintenance work on equipment by using only a personal mobile terminal to identify status information of essential control points of various equipment installed throughout the building in real time at the work site, without a separate wired or wireless internet connection, remote control program, or built-in installation program. This enables effective performance of equipment inspection and maintenance work, and allows not only maintenance experts but also maintenance personnel or on-site facility managers to easily check the status of equipment and perform inspection and maintenance work without the need for separate work assistants.

[0021] In the present invention, the time interval for transmitting messages may be uniformly determined, but it is preferable to allow the operator to input it before dispatching to the site, taking into consideration their proficiency or the type of equipment to be inspected or maintained. To this end, the processing unit preferably comprises a message transmission time interval designation module that receives the time interval for transmitting the message text data and stores it in the storage unit.

[0022] Meanwhile, since it takes some time from moving from the central control unit to the work site, preparing for the work, and starting the actual work, it is desirable to allow the worker to input the message transmission start time by considering the location of the work site, etc. To this end, it is desirable for the processing unit to be equipped with a message transmission start time designation module that receives the transmission start time of the message text data and stores it in the storage unit.

[0023] For the message transmission start time, you can enter the start time as 'hours and minutes' or the time interval as 'after a few minutes'.

[0024] In the building integrated control system according to the present invention, the control point database includes the location name, the name of the field device installed at each location, and the control point information of each field device. It is preferable that the transmission target control point selection module displays each field of the control point database on the display means to enable the selection of a control point to be inspected or maintained. According to this feature of the present invention, the transmission target control point can be easily selected by collectively selecting the control points by selecting a required control point among the control points listed on the display, or by selecting a work target location or device.

[0025] In addition, in the building integrated control system according to the present invention, the data storage unit stores an inspection / maintenance guidance information database containing field equipment image data that displays the images of the field equipment, along with the names and locations of the field equipment and the names and locations of control points associated with the field equipment; and the message transmission module transmits image data corresponding to the field equipment subject to inspection / maintenance selected by the transmission target control point selection module before sending the text data for the message. According to these features of the present invention, even a worker unfamiliar with the work site or equipment can easily identify and access the location of the equipment within the building and the location of control points, such as sensors installed on the equipment, through image messages, thereby enabling the smooth progress of the work. Effects of the invention

[0027] According to the building integrated control system of the present invention, a worker can perform inspection and maintenance work on equipment by using only a personal mobile terminal to identify status information of essential control points of various equipment installed throughout the building in real time at the work site, without a separate wired or wireless internet connection, remote control program, or built-in installation program. This enables effective inspection and maintenance work on equipment, and allows not only maintenance experts but also maintenance personnel or on-site facility managers to easily check the status of equipment and perform inspection and maintenance work without the need for separate support personnel.

[0028] In addition, even workers unfamiliar with the work site or equipment can easily identify the location of the equipment within the building and control points, such as sensors installed on the equipment, through image messages, thereby enabling them to proceed with the work.

[0031] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. Identical or similar components regardless of drawing symbols will be assigned the same reference number, and redundant descriptions thereof will be omitted. Furthermore, in describing the embodiments disclosed in this specification, if it is determined that a detailed description of related prior art may obscure the essence of the embodiments disclosed in this specification, such detailed description will be omitted. Additionally, the attached drawings are intended only to facilitate understanding of the embodiments disclosed in this specification, and the technical concept disclosed in this specification is not limited by the attached drawings; it should be understood that the drawings include all modifications, equivalents, and substitutions that fall within the spirit and technical scope of the present invention.

[0032] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0033] FIG. 1 is an overall configuration diagram of a building integrated control system according to an embodiment of the present invention. The building integrated control system is composed of a central control device (100) that manages and controls various facilities and systems installed in a building, and a remote control panel (210) that controls the operation of field devices (22), collects and analyzes information of field devices to respond to them, and transmits the collected and analyzed information to the central control device.

[0034] The remote control panel (210) controls the field equipment under the control of the central control device (10), but a direct digital controller (DDC) control panel unit is generally applied to enable independent control of the field equipment. The DDC control panel unit senses or measures various status information of the field and transmits information or data corresponding to a request signal from a management server, such as a control station or control PC of the central control device (100), through a wired or wireless network (230). As illustrated in FIG. 1, it is installed in the pump room, air conditioning machine room, geothermal machine room, electrical room, water tank room, etc., respectively, to control pumps, fans, water levels, etc.

[0035] The central control device (100) is a device that is placed in a central control room (110; control room or disaster prevention room) and operated by an integrated management entity. It is equipped with HMI (Human Machine Interface) software to collect various status information of the site, output monitoring results, and perform control and management functions based on the results. It is equipped with a management server (10) having a data storage unit (11), a processing unit (12), and a communication unit (13), an input means (20) such as a keyboard and mouse for inputting data into the management server, and a display means (30) for displaying data output from the management server, thereby managing and controlling a number of field devices (220) installed in a building through a DDC control panel unit.

[0036] FIG. 2 is a block diagram of a central control device (100) according to an embodiment of the present invention. In the data storage unit (11) of the management server (10) constituting the central control device (100), a control point database (11a) is stored, which includes the names of field devices, the names of control points of each field device, and status information of each control point transmitted from the DDC control panel unit. Additionally, as illustrated in FIG. 3, an inspection / maintenance guidance information database (11b) is stored, which includes image data displaying the names and locations of field devices and the names and locations of control points related to the field devices, along with drawings or photos of each field device.

[0037] The processing unit (12) of the central control device (100) is equipped with a transmission target phone number designation module (12a) that receives a worker's mobile terminal phone number and stores it in a storage unit (11), a transmission target control point selection module (12b) that receives a control point of a field device to be inspected / maintained and stores it in a storage unit (11), a transmission target control point status information reading module (12c) that reads the name and status information of the control points selected by the transmission target control point selection module from the control point database (11a) at preset time intervals, a text data conversion module (12d) that converts the name and status information of the control points read by the transmission target control point status information reading module into text data for messages, and a message transmission module (12e) that transmits the text data for messages to the transmission target phone number through a communication unit (13) at preset time intervals.

[0038] The transmission target phone number designation module (12a) can display a phone number input box to receive the current worker's mobile phone number when the inspection mode button displayed on the display means (30) is clicked, as exemplified in FIG. 4, or display a list box of pre-registered phone numbers to select a phone number.

[0039] The transmission target control point selection module (12b) displays a location list box on the display means (30) as exemplified in FIG. 5, and when a location is clicked, the equipment and control points of that location are displayed, and the required control point can be selected. Additionally, when a control point is right-clicked, image information of the sensor corresponding to that control point is read from the inspection / maintenance guide information database (11b) and displayed.

[0040] The transmission target control point status information reading module (12c) reads the names and status information of the control points selected by the transmission target control point selection module (12b) from the control point database (11a) at preset time intervals, and the name and status information data of the control points read in this way is converted into message text data by the character data conversion module (12d) and transmitted to the transmission target phone number through the communication unit by the message transmission module (12e).

[0041] Figure 6 is a diagram showing an example of a message transmitted to a worker's mobile terminal, showing an example where a location, device name, control point name, and status information of the control point are transmitted. This allows the worker to perform work while simply checking via a mobile phone whether various sensors installed in the equipment are functioning properly, whether the indicator values ​​or measurement values ​​of the sensors are accurately transmitted to the integrated management system without errors, in other words, whether there are any abnormalities in the signal transmission system such as various status values, and how the equipment operates when operating or replacing specific parts of the equipment.

[0042] Although the time interval for transmitting messages may be uniformly determined, it is desirable to allow the operator to input it before dispatching to the site, taking into account their proficiency or the type of equipment to be inspected or maintained. To this end, the processing unit is provided with a message transmission time interval designation module (not shown) that receives the time interval for transmitting the message text data and stores it in the storage unit.

[0043] According to the test results, a message transmission time interval of about 30 seconds to 1 minute was appropriate, but an appropriate value is selected depending on the operator's skill level or the type of device.

[0044] Meanwhile, since it takes some time from moving from the central control unit to the work site, preparing for the work, and starting the actual work, it is desirable to allow the worker to input the message transmission start time by considering the location of the work site, etc. To this end, the processing unit is equipped with a message transmission start time designation module (not shown) that receives the transmission start time of the message text data and stores it in the storage unit.

[0045] For the message transmission start time, you can enter the start time as 'hours and minutes' or the time interval as 'after a few minutes'.

[0046] The termination of message transmission may be achieved by having the operator return to the control room after completing the task and click the termination button, or by instructing an assistant operator in the control room to click the termination button via telephone. Additionally, similar to the aforementioned start time, a method is possible in which a message transmission end time designation module (not shown) is provided in the processing unit to input the end time or time interval.

[0047] FIG. 7 illustrates an embodiment in which, prior to the transmission of a text message, image data corresponding to a field device for inspection / maintenance selected by a transmission target control point selection module, i.e., inspection / maintenance guidance information, is transmitted. According to this embodiment, even a worker who is not familiar with the work site or the device can easily identify and access the location of the device within the building and the location of control points, such as sensors installed on the device, through the image message, thereby enabling the work to proceed smoothly.

[0048] Although the present invention has been described above with reference to specific examples for convenience of explanation, the above-described embodiments are merely exemplary embodiments of the present invention, and various modifications or changes are possible within the spirit and scope of the present invention as specified in the claims.
