Or it relates to a building facility control system capable of performing a central control.

In general, facilities are typically installed in various types of buildings in large commercial districts such as office buildings, factories, hotels, restaurants, hospitals, supermarkets, warehouses, department stores. Conventional air conditioning equipment typically includes an air conditioner heater / cooler unit, an air handling unit (AHU), a precooling air handler (PAH), and a fan coil unit (FCU). Basically, the air conditioning system not only adjusts the air temperature in a confined room to keep people comfortable inside, but also to prevent the inconvenience and health risks caused by the high carbon dioxide levels inside the building. Can supply fresh air outside.

The building's facilities operate for a long time or even 24 hours a day. For example, the energy consumed by the air conditioning system depends on many factors such as the size of the space to be controlled, external temperature, exposure to direct sunlight, occupancy rating, external door usage and other usage patterns.

 Therefore, in the case where the access monitoring device is provided in an environment in which the air conditioner is installed, energy is saved, especially when the access monitoring device includes an automatic door and a window-type ventilation fan for human access. However, there are many factors that allow the access monitoring device to allow the door to be opened, such as forgetting to close the door, not closing properly, or intentionally leaving the door open. According to the air conditioner design according to the prior art, in order to control the temperature of the environment in which the air conditioner is installed to a preset temperature, the air velocity or the speed when the access monitoring device keeps the door open and the hot air enter the inside The compressor use level must be increased. In essence, increasing the air speed or compressor load consumes more energy.

In particular, in some public places, such as office buildings, schools, and other buildings, air conditioning facilities sometimes remain operational even when no one is inside, resulting in unnecessary energy consumption.

The access monitoring device 102 is for measuring the time interval of opening / closing the monitored door 20 and the window 21, and this data on the air conditioning usage pattern is based on the detected opening / closing conditions, The data for the air conditioning usage pattern includes both the open state and the closed state of the door 20 and the window 21 and the time interval.

Specifically, the access monitoring device 102 mainly detects the use state of the door 20 and the window 21. The entrance monitoring device 102 also includes one or more sensors, such as a one-way infrared detection unit, a two-way infrared detection unit, an electromagnetic switch, an ultrasonic sensor unit, or a radio frequency identification (RFID) unit. Such a sensor is installed in each door 20 and window 21, and an open / closed state of each door 20 and window 21 is detected through at least one of the aforementioned units.

The air conditioning control device 104 includes a storage module 1042 for storing a set of preset control parameters corresponding to different data for the air conditioning usage pattern, wherein the air conditioning control device refers to the preset control parameters to determine the access monitoring device ( Control and control of the air conditioning installation 100 is executed based on the data on the air conditioning usage pattern generated by 102.

However, the above-described conventional facility control cannot be actively controlled due to the central control impossible, and the control by the wired method has a high construction cost and is vulnerable to rapid response due to user demand or physical change. The way is required.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, in the present invention, the facility of a building means a lighting facility, an air-conditioning facility, a crime prevention facility, a fire-fighting facility, etc., so that individual control or central control is possible based on the wireless network of the present invention. To this end, the type of transmission of the signal and data applied in the present invention implements a form of transmitting an event (sensing information, etc.) generated in the facility control terminal to the server terminal, or transmits a signal for controlling the individual facility control terminal from the server terminal. Take form.

Accordingly, in the present invention, as shown in FIG. 2, a data transmission node method is provided. The minimum distance between OPDs is obtained by using relative coordinates of a transmission source (O), a transit node (P _n ), and a transmission destination (D). OPD minimum distance algorithm is used to determine the priority of the transit node (P _n ) within the communication module transmission and reception radius.

That is, the building equipment has unique ID information (P1, P2, P3 ... Pn), and holds the coordinate information measured when the building equipment is installed. Therefore, the distance information between each building facility is recognized. The transmission node list information includes ID information of a building facility located within a radius in which communication is possible with respect to any one transmission node (O: Origin). Then, the distance to the destination coordinate is calculated based on the coordinate information corresponding to the ID information, and any building facility having the minimum distance to the destination is set as the highest priority.

Here, P1, P2, P3, P4 are located in the building equipment located within the radius of the communication smoothly around the transmission node (O), P2 node having a minimum distance to the building equipment (D: Destination) having the transmission destination coordinates Has the highest priority. As illustrated, P1 has a second priority and P3 has a third priority. The above priority is a priority for attempting communication. If communication with the ID of the corresponding rank is not possible due to a communication failure, the corresponding ID is reset to the lowest priority and communication with the ID having the second priority is performed. Try. In the present invention, such a prioritization algorithm will be referred to as a minimum distance algorithm.

Therefore, when a communication node is determined by the above-described transmission node list information, each node communicates between building facilities according to the communication node. However, if communication is not possible due to a communication failure in any one communication node, the communication module of the node attempts to communicate with any one communication module based on the priority set according to the minimum distance algorithm. The corresponding communication node notifies a higher node of a communication failure due to a communication failure.

In addition, the communication node communicates with any one communication module by repeating the above process, and the ID information having succeeded in the final communication is recognized by the communication node, and is reset to the highest priority.

Eventually, communication nodes of each building facility are set by the transmission node list information, but each communication node determines an arbitrary communication node based on the minimum distance algorithm according to the situation. This determination is set as the highest priority in the corresponding communication node, and the communication node which has successfully communicated is notified to the upper node. As such, the communication node information that has successfully communicated through the upper node is finally collected by the gateway, and the collected information is assumed to be a transmission success list.

3 is a block diagram showing a building facility control system. First, the server proposed in the present invention is interlocked with each building equipment control terminal provided in a plurality of buildings, each building equipment control terminal (O) controls the environment for the building equipment in the building.

That is, the building equipment control system according to the present invention, the building equipment is distributed a number of each building provided in a plurality of buildings, the short-range communication module is mounted; A building facility control terminal provided for each building to hold coordinate information on the building facilities distributed in the corresponding building, and to control each building facility; A gateway for receiving event information for each building facility and transmitting environmental control information according to a control control for each building facility required from the building facility control terminal; And receiving coordinates of the building facilities for each building by the building facility control terminal, and generating transmission coordinate information, next transmission coordinate list information, and transmission destination coordinate information for each building facility based on the coordinates of the building facilities. And constructing minimum distance information for the pass-through node within a transmission / reception radius of the short-range communication module, and holding the transmission node list information having priority determined for the communication order between building facilities based on the minimum distance information, and transmitting the node. It is made of a server for transmitting a control control signal for controlling the building equipment according to the priority by the list information to the building equipment control terminal.

Here, each building facility control terminal (O) has the last successful ID information that the communication was performed between each facility, and registered and stored as listed information. Therefore, each building facility control terminal O has a plurality of success ID information, and preferentially uses the latest success ID as the ID for connecting to the communication. Of course, when the communication is not performed by the latest successful ID information, the communication connection is performed using the success ID information registered subsequently.

As shown in the figure, if the building facility control terminal O wants to provide its event information to the gateway based on the latest success ID, the building facility control terminal O transmits the event information to P2 which is the latest success ID information.

And, after receiving the event information of the building equipment (P1), the building equipment (P2) performs communication based on the latest success ID information held by the building equipment (P2). If the last successful ID of the building equipment P2 is P4, the building equipment P2 transmits the cumulative event information to the building equipment P4.

The cumulative event information is event information transmitted from an upper node and information accumulated by own event information. The building facility P2 receives its event information and event information generated by the building facility control terminal O. It is. Therefore, the final building facility D transmitting the event information to the gateway transmits the event information transmitted from the upper node in a batch. The cumulative event information includes ID information of the building equipment which has passed along each path, and the status information of the building equipment, for example, the lighting state of the lighting equipment, the air conditioning state of the heating / cooling equipment, the human body control state of the security equipment, and the fire fighting equipment. Fire detection status information, and the like.

The event information is information stored in a memory provided in a control device interoperating with a communication module, and interlocked with a detection circuit for detecting a state of a building facility. The detection circuit includes various measuring sensors and detection sensors for building equipment, and includes, for example, a temperature sensor and a pressure sensor in an air conditioning system, an illuminance sensor in a lighting facility, a CCTV motion detection sensor in a crime prevention facility, and the like. Can be used. The above-described detection circuit is converted into a digital signal through a separate control device provided in each building facility and stored in the internal memory.

Meanwhile, the building facility P2 communicates with P4, which is a recent success ID, and transmits cumulative event information therefrom. At this time, the building facility P2 notifies the building facility control terminal O that communication with the building facility P4 was successful. Therefore, the building facility control terminal O maintains communication with the building facility P2 which is the current successful ID. In addition, the building facility (P4) attempts to transmit the cumulative event information to the gateway.

If, when the communication between the building equipment (P4) and the gateway is not made, that is, a communication failure occurs, the building equipment (P4) has not been communicated due to a communication failure to the building equipment (P2), the upper node. Notify. At this time, the building equipment (P4) notifies the communication failure to the building equipment (P2), the upper node, and also transmits its own event information. Accordingly, the building facility P2 generates cumulative event information including event information of the building facility P4 and resets its latest success ID information to the lowest rank.

That is, the building facility P2 changes the priority of a plurality of successful ID information. The ID information that fails to communicate currently is set as the lowest priority, and the ID set as the second priority is set as the highest priority. Here, when the ID set as the second priority is P5, the building facility P2 transmits the cumulative event information to the building facility P5. If the building equipment P2 does not communicate with the building equipment P5, the latest success ID information of the building equipment P2 is changed again, and the building equipment P1 is notified to the building equipment P1. The node path from the building equipment P1 is reset again.

However, when the communication between the building equipment P2 and the building equipment P5 is made, and the communication between the building equipment P5 and the gateway is successful, the building equipment P5 is used as the latest success ID of the building equipment P2. Register. The gateway receives cumulative event information through the building facility P5.

As described above, the cumulative event information includes event information for each building facility, and route information including ID information for the transit node exists, and the gateway can determine an optimal communication path based on the route information. do. That is, the gateway secures a transmission success list. Here, the cumulative event information provided to the gateway is not provided only in one building facility, but cumulative event information may be provided from the two or more building facilities to the gateway according to the path of each building facility.

Meanwhile, as another embodiment of the present invention, a broadcast method that may be used when the server terminal sends the same data or control signal to all the facility control terminals may be applied.

That is, as shown in FIG. 4, the gateway transmits reverse list information and control information for the current successful transmission list information to the adjacent building facility. Here, the adjacent building equipment is at least one building equipment as the last ID of the transmission success list, that is, the highest ID of the reverse list.

The building facility corresponding to the highest ID of the reverse list receives the reverse list information currently received, and then changes data, for example, air conditioning control, lighting control, and room temperature control, according to the control information. The reverse list information and the control information are transmitted to at least one building facility according to the reverse list.

Since the reverse list information is a list of the latest successful IDs, communication is attempted based on the node where communication was recently performed. Therefore, the communication connection probability is very high, and the transmission speed for control information for each building facility is very fast. That is, when the same information is to be transmitted to each building facility, the gateway broadcasting shown in FIG. 5 is used, thereby increasing the efficiency of data transmission.

In this embodiment, each building facility continuously updates the latest success ID information, and the route information thereof is fed back to the gateway 213 to modify the transmission success list information.

According to the method, the building equipment broadcasting method of the broadcast mode of the present invention is implemented in the same manner, the building equipment broadcasting can be used when transferring information for the purpose of linkage between the building equipment and building equipment. That is, it is applied to control the lighting of a plurality of building equipment located in a category set in an arbitrary group, and controls the environment for the building equipment in the group with respect to any one specific building equipment. Therefore, any one specific building equipment is to perform broadcasting to building equipment in the group.

On the other hand, in the broadcast mode proposed in the present invention, the communication of the mobile unit is also possible, which attempts the omnidirectional radiation communication in the terminal attached to the mobile unit, the position is detected by the communication terminals around it is connected to the server can be controlled To do so.

As described above, the environmental control of the building equipment according to the present invention may take a method of placing gateways by dividing the area into Z layers by floors or by zones, as shown in FIG. 6. This is due to the fact that most communication signals do not pass through the slab between floors because the general building is composed of several floors.

In addition, the newly installed facility control terminal receives the node ID and coordinate values within the transmission / reception distance from the server by communicating with the communication module of the nearby terminal. Update the transmission list of the transit nodes around the equipment control terminal so that it can be expanded and become a member of the network.
