Description

REMOTE FACILITY MANAGEMENT USING LOW-POWER BRODBAND NETWORK}

The present invention relates to remote facility management, and more particularly, to remote facility management using a low power broadband communication network.

In general, management systems for comprehensive monitoring and control in various fields such as air conditioning, lighting, power, water, and fire surveillance are being installed in various facilities including large buildings, and recently, with the development of IT technology, a wide range of personnel is being developed. A PLC (Programmable Logic Controller) has been actively introduced in the management system to enable management.

These PLCs are devices that enable program control by replacing the functions of conventional relays, timers, counters, etc. with semiconductor devices, and provide special functions such as logic, sequencing, timing, counting, and calculation through digital or analog input/output modules. It is defined as an electronic device of digital operation that uses programmable memory to perform and controls various types of machines or processors.

These PLCs have manufacturer-specific protocols such as Profibus, DeviceNet, Modbus, MelsecNet, Interbus, AS-I, Foundation, Fieldbus, LonWorks, and Vendor-dependant, so they can integrate and control various types of PLC equipment installed in industrial sites. Technology is required.

In the integrated management of various PLCs, a means capable of preventing damage to electronic and communication components due to power imbalance or surge inflow is required for stable monitoring as well as protocol conversion between communication units. In particular, in situations where damage from lightning strikes or ground potential rises (thunder strikes caused by reverse surges) often occurs, a management system composed of a large number of electrical appliances, electronic circuits, and communication devices uses low-power, high-density integrated circuits, resulting in low surges. Voltage can also be fatal.

To this end, it primarily communicates with power lines connected to power lines, communication lines, data networks, CCTV circuits, and electronic equipment through various protection devices composed mainly of nonlinear elements such as MOV (Mental Oxide Varistor), fatigue tubes, and semiconductor devices.

Attenuation of dangerous over-voltage and over-current at very short moments appearing on lines, etc., but when surge is not blocked due to various accidents in facilities, it can lead to major accidents such as expensive equipment damage and fire, as well as situational propagation. This led to disturbing problems.

In the present invention, the compartments may be divided into structural partition walls of a facility or divided into compartments through setting according to administrative needs, and elements for intensive monitoring and management are usually different depending on the use of the space.

The detection unit 10 is composed of a plurality of detection means for performing image collection, fire detection, flood detection, and air conditioning detection from the compartment according to such a setting to collect monitoring information. Due to the characteristics of the compartment, various sensing means can be provided in one compartment to perform comprehensive monitoring and management, but it is desirable to perform intensive monitoring and management of factors that are relatively low in probability of accident occurrence.

For example, in the compartment for storing or using flammable materials, the fire will be naturally monitored, and since the possibility of fire is relatively small in a compartment such as a passage through a person, it is more important to monitor the number of people using fire rather than fire. Will be done. In addition, in the compartment where the pipeline for supply of water passes, such as a water tank or a water tank, monitoring of immersion will be performed. Air-conditioning detection will occur in the compartment where this difficult object is stored.

As mentioned, the camera unit 11 is mainly used for monitoring the entrance and exit of personnel, but in some cases, it can also be used for monitoring fire.

The fire detector 13 detects smoke or gas generated during a fire or a fire in accordance with a possible cause of fire, and the flood detector 14 induces discharge of water when flooded or at the bottom of a compartment located mainly underground. It is installed in waterways and wells.

In addition, the water storage unit 10 is installed in a storage means for supply of water required in a facility such as a water tank to monitor the storage amount. The temperature/humidity detection unit 10 is a sensor that detects general temperature and humidity, and is installed in a space where a person is active, as well as in a section requiring temperature and humidity management due to the characteristics of equipment or items, and the gas detector 17 monitors fire. It is also possible, but it is equipped with an appropriate sensor so that it can check whether the substance leaks when handling a specific substance in the compartment, including fine or ultra-fine particles, which are a recent problem. This is a configuration for air conditioning management together with the temperature and humidity detection unit 10, and is used to maintain conditions such as temperature, humidity, bacteria, odor, and airflow in the room in a state suitable for the purpose of use of the place.

In addition, the weather information collection unit 18 may measure the current weather conditions by temperature/humidity and rainfall installed outdoors, but collect weather information of the region from various webs that provide weather information.

The counterpart 20 is composed of a plurality of countermeasures that perform an operation in response to the monitoring information collected from the detection section 10, that is, various detection means. In the present invention, the countermeasure is basically set to Fire extinguishers that supply fire extinguishing water to the intellectual compartment by operating in response to a fire such as a sprinkler, as well as a composite door (21) that performs security and fire protection functions through opening and closing, although movement of people and cargo is made between each compartment along A pump 22, a drainage pump 23 that transfers water in the compartment to a specific place when flooding occurs, a cooling and heating unit 24 for heating and cooling the compartment, and a ventilation fan 25 for discharging the air in the compartment to the outside, It consists of a power circuit breaker (26) to cut off the power supplied to the compartment, and a general lighting (27) and emergency lighting (28) provided in the compartment.

Such a countermeasure means is a basic configuration for managing facilities and responding to various accidents and abnormal conditions. In addition, various countermeasures may be provided.

The relay unit 30 collects the monitoring information collected from the detection means to integrate and manage various detection means as different communication protocols are applied to each manufacturer, but is easily managed by the common protocol, that is, the control unit 40 It is a configuration that is converted to a designated protocol and relayed. Algorithms for conversion of various protocols can be applied, but as the detection means for facility management are many based on lonworks, it is possible to apply a batch conversion method based on a modbus that is easy to process. have.

In the present invention, the relay unit 30 has a very important configuration, and thus, when damage occurs, the operation of the entire system may be paralyzed, so that it is installed so as not to be exposed to the outside as much as possible. It is protected by being covered with a protective material with heat resistance. Preferred examples of the protective material may be realized by combining a fumed silica, a WDS high temperature insulating material formed by compressing a micro porous material and a metal thin film to protect the relay unit 30 through a stable heat insulation effect even at high temperatures. In particular, such a high-temperature insulating material has extremely low thermal conductivity and can be used up to 1100°C, so that it is possible to ensure stable relaying and operation of the information even in a fire situation.

The control unit 40 is configured to manage by collecting monitoring information and controlling countermeasures in response thereto, and includes an interface 41, a determination unit 43, and an alarm unit 44.

The interface 41, as an input/output means, basically classifies the monitoring information transmitted from the relay unit 30 into sections and outputs it to the manager, so that the manager can check the situation of each section at a glance, as well as classification by section. Various sorting of collected surveillance information is possible, including classification according to surveillance information.

The judging unit 43 is configured to classify and analyze the collected monitoring information to determine an abnormal condition. In addition, whether there is a fire or flood, a short circuit or a short circuit, abnormal high and low temperatures, high and low humidity, insufficient water storage, and unauthorized The invasion of a person and the situation in which the amount of a specific substance in the air is excessive are comprehensively determined, and a reference value for determining this is set in advance.

The alarm unit 44 is configured to transmit the corresponding section and status information to the designated terminal when the determination unit 43 determines an abnormal condition. By transmitting an alarm so that the situation is recognized and action is taken, information on the terminal to which the alarm is delivered is set in advance for each person in charge or for each person in charge.

The emergency power unit 50 is basically a state in which charging is performed through commercial power supplied at all times, and when commercial power is not supplied smoothly due to an accident, it is replaced with a configuration to supply power for a certain period of time. A portion 51, a storage battery 52, and a switching portion 53 are provided.

The conversion unit 51 is a configuration that converts commercial power into a power source suitable for charging the storage battery 52. Since commercial power is AC power, it is converted to DC power of a set voltage to charge the storage battery 52. do.

The switching unit 53 is a switching circuit for switching the power supplied to the control unit and the corresponding unit and the relay unit or the storage battery 52 according to the determination of the determination unit. When commercial power is not used for maintenance or other reasons, the commercial power supply to the control unit 40 and the counterpart 20, the relay unit 30, and the conversion unit 51 is cut off, and the storage battery 52 The power supply is made through, and in a normal state, commercial power is supplied from the power line H to the conversion unit 51, including the control unit 40, the corresponding unit 20, the relay unit 30, and the above. Charge the storage battery 52 to be made.

Likewise, in the present invention, the emergency power unit 50 has a very important configuration, and thus, when an emergency occurs, the operation of the entire system may be paralyzed. Therefore, it is installed so as not to be exposed to the outside as much as possible. It is desirable to be protected by being covered with the above-mentioned protective material, which is shielded and heat resistant.

2 is a block diagram showing a configuration and connection relationship according to another embodiment of the present invention. Here, as the basic configuration of the preferred embodiment described above, configurations for more efficient management and response when an abnormal situation occurs are added. In another embodiment of the present invention, the control unit 40 includes an input unit 42 and a storage unit ( 45), the position setting section 46, the communication section 47, and the configuration of the authentication section 48 are added.

The input unit 42 is configured to receive partition information and utilization information from a manager or an operator, and may input information in conjunction with the interface. In other words, it can be used as a criterion for determining which elements should be intensively monitored depending on which compartment is used for what purpose or what work is being performed. For example, if access is controlled by raising the security level during a certain period of time in a specific compartment, intensive monitoring of personnel access should be performed, and if work is carried out with flammable materials or storage of flammable materials is performed, intensive monitoring of fires can be performed. Since there will be a need, the manager or the operator inputs the section information and the utilization information including such contents through the input unit 42 in advance.

The storage unit 45 includes the use and utilization information of each section input through the input unit 42, the corresponding sensing means and code for the corresponding sensing means, the sensing means and the corresponding means and the emergency power unit ( 50) is a configuration in which the operation information is stored in advance.

That is, as an example, if the utilization information is related to a fire, the corresponding detection means will be the fire detector 13 and the response means will be the fire extinguishing pump. That is, as an abnormal situation is determined through various detection means and detection means corresponding to a possible occurrence situation according to various utilization information, response means that needs to be acted upon is stored as a code.

As the use and utilization information of these compartments are received, it is necessary to monitor the compartments at a higher level than usual. In some cases, it is possible to monitor the empty compartments and reduce the fatigue of the system. As the compartment is used for a specific purpose, a situation may arise, such as being assigned a surveillance level. In the present invention, such a monitoring level is managed as a posture. Stability can be managed in various ways and levels for management efficiency.For example, 1 for an empty compartment for fire surveillance, 2 for a general use compartment with a slightly lower fire risk, and 3 for a compartment with fire risk work In the case of position 1, there is no monitoring, and in case of position 2, regular monitoring through a fire detector, in case of position 3, the monitoring cycle is increased or monitoring is performed even when adjacent sections are empty. Efficient monitoring and management can be achieved by enabling differential monitoring and preparation according to the situation, such as maintaining the stand-by state of the fire pump and maintaining the automatic closing state of the fire door.

The posture setting unit 46 sets a posture based on the utilization information input through the input unit and the criteria set according to the determination result of the determination unit 43 and calls the corresponding operation information from the storage unit 45 Indentation control means and control means.

As mentioned, the stance designation is made by reflecting the utilization information and the result of the judgment, and by reflecting this, the monitoring cycle of the designated monitoring means or the operation or non-operation of the monitoring means for the adjacent compartments and the corresponding countermeasures will operate at any time. In order to be able to stand by, control is made to take place. If it is determined that the determination unit 43 is in an abnormal state, the operation of the countermeasure means can be performed immediately according to the setting.

The posture setting unit 46 determines the possibility of a lightning that is a major cause of surge and classifies the boundary level into a normal state with a small lightning probability and a boundary state with a large lightning probability, and the weather information collecting unit 18 ) Receives weather information, including weather, from which the boundary level is determined.

That is, access to the Korea Meteorological Administration or weather-related granular weather information can be obtained through various apps or sites related to the weather, and the posture setting unit 46 analyzes the transmitted weather information and strikes according to the set criteria. The possibility of occurrence is judged. For example, when the weather is clear and the probability of precipitation is low, it is determined as a normal state, when it rains or when the precipitation probability is high, it is determined as a boundary state. In particular, when a lightning warning is in effect in the area, it can also be determined as a boundary state. At this time, as mentioned above, as the weather information is subdivided by time, it is possible to calculate the end time of the poised to switch from the alert state to the normal state.

The communication unit 47 is a communication unit for communication with the external terminal 60, and is a communication module that can connect to a commercial mobile communication network and communicate with a designated terminal.

The authentication unit 48 basically transmits the monitoring information transmitted to the control unit 40 through the relay unit 30 to the terminal 60, that is, a designated terminal 60 of the person in charge or the entire manager, It is configured to control the corresponding means and the emergency power unit 50, that is, the switching unit 53 according to the control signal transmitted from the terminal 60. At this time, by sequentially granting control authority in accordance with the currently set posture, the holder of the terminal 60 is prevented from arbitrarily controlling the countermeasure means and the switching unit 53 to prevent secondary accidents due to incorrect control.

In addition, in another embodiment of the present invention, the emergency power unit 50 includes a current measurement unit 54 and a power management unit 55.

The current measuring unit 54 is configured to measure the current of the storage battery, that is, the remaining amount of power stored in the storage battery, and the power management unit 55 is configured to control the power use of the storage battery to the switching unit 53 Power saving measures to control the power consumption of the storage battery 52 step by step according to the operation information of the emergency power supply unit 50 of the storage unit from the time when the power of the storage battery is used to the termination setting time according to the posture are made. to be. To this end, the operation information of the emergency power unit 50 includes information about a priority order in which power is supplied and cut off in response to the poised and poised maintenance time and the remaining power of the battery by hour. For example, the general lighting 27 has a higher power interruption priority than the emergency lighting 28, and the emergency lighting has a very low blocking priority.

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.
