Description

ELECTRIC FIRES PREDICTION SYSTEM CAPABLE OF BREAKING STANDBY POWER FIELD OF THE INVENTION [0001]

The present invention relates to an electric fire prediction system, and more particularly, to an electric fire prediction system capable of automatically detecting and detecting an arc, a spark, an overload, a short circuit, The present invention relates to an electric fire prediction system including a standby power interruption function so as to prevent a fire from being detected before a fire occurs due to a predictive alarm through output or the like.

Electric fires are a total of 35% of movable electric heaters, 27% of electric wires and telephone wires, 14% of electric appliances and 9% of electric appliances. , 5% of wiring equipment, 5% of fixed electric heaters, and the occurrence rate of spark 24%, leakage 15%, contact 12%, insulation 11% and overcurrent 8% It is becoming a cause.

Looking at the electrical facilities of rural households and housing complexes, it is close to half of the pensioners / householders who have been left in the condition of aged electrical equipment for more than 10 years. Most of them use flammable building materials (vinyl, insulating cover, urethane, etc.) due to deterioration of housing facilities. In the case of poultry houses, the heat cover and winch type houses account for 68% have. There is also a lack of awareness of the manager's fire hazard. Overload and short-circuit exposure due to unreasonable expansion of electrical facilities that do not take account of electrical capacity are another major problem of electric fires. Excessive electricity usage due to the installation of equipment (hot air fan, warming lamp, ventilator) in the existing electric facility causes fire due to overload, and fire occurs due to overload caused by the artificial connection of the electric outlet.

Currently, electric fire detection systems are making a lot of progress. The purpose of the installation of the electric fire detection system is to detect and warn fire automatically, and to respond early to prevent the occurrence of electric fire. In case of a fire, not only the direct primary damage by the loss but also the secondary damage by the waterproofing in the fire suppression and the strength of the building by the flame cause very great property damage and sometimes it may take away valuable person. Predictive discovery is important to alleviate fire damage.

On the other hand, devices such as a multi-outlet which can interrupt the power supply have been actively studied for a method of blocking the standby power. Standby power is one of the main causes of power shortage due to the power that the electronic device consumes so that the user can sense the input even though the user does not use the electronic device. However, the existing electric fire detection system did not consider standby power as a subject of detection or interception. This is because it is not easy to cut off the electricity arbitrarily because electric fire monitoring system supplies electric power to a large number of electronic devices in contrast to a multi-outlet for controlling some electronic devices. In addition to the conventional electric fire detection system, even a multi-outlet that can block the standby power requires direct manipulation of the user in order to supply the interrupted power again. Especially, unlike the multi-outlet which is placed around the electronic equipment used by the user, the electric fire detection system is often arranged according to the structure of the building irrespective of the position of the electronic device. There is no case in which a shutdown function for standby power is added in addition to the power cutoff. Therefore, in order to cut off standby power, each of a plurality of electronic devices must be connected to a multi-outlet having a standby power cutoff function. In this case, in order to re-supply the cut-off power, Thereby causing inconvenience to the user.

4 shows a configuration of a standby power interruption circuit of the electric fire prediction system of FIG.

The electric fire prediction system of the present invention measures the load power of an electric device connected to a plurality of ports (PT) and, when it is determined that the electric device is in a standby state based on the measured load electric power, The relay (RL) blocks.

4, the standby power interruption circuit includes a first detection unit 211, a memory unit 220, an auxiliary control unit 230, a relay unit 270, an auxiliary power source PW, and a second detection unit 212 do.

In this case, the input power source IN is a power source input to the electric fire prediction system. For example, if the electric fire prediction system uses a domestic commercial power source, an AC power source of 220 V may be input.

The first detection unit 211 includes a plurality of first detectors included in the sensor unit 210 of FIG. The plurality of first detectors are provided corresponding to the number of the plurality of ports (PT), and each detects the load power of the corresponding port. That is, the voltage and the current.

When power is supplied through the corresponding port, the memory unit 220 stores the load power at which the corresponding first detector of the first detection unit 211 is initially detected as the reference standby power. At this time, the memory unit 220 separately stores the load power detected by each of the plurality of first detectors. That is, the memory unit 220 stores the number of reference standby powers corresponding to the number of currently connected electronic apparatuses. Here, the initial detected load power means a load power measured for a predetermined initial time (for example, 0.2 second) after the power is supplied to the corresponding port, and in some cases, have.

Also, the memory unit 220 can store the individual maximum reference power and the integrated maximum reference power usable in the corresponding port.

The auxiliary controller 230 receives the load power of each of the electronic apparatuses detected by the plurality of first detectors of the first detector 211, If the load power detected by the first detector is less than or equal to the corresponding reference standby power for a preset time (for example, 1 to 10 seconds), the relay blocking signal is transmitted to the relay unit 270 To the corresponding relays among the plurality of relays RL. That is, if it is determined that the load power detected by the first detector is equal to or less than the reference standby power stored in the memory unit 220, the auxiliary controller 230 determines that the connected electronic device is in the standby state. Therefore, it is possible to determine that the power consumed by the electronic apparatus is the standby power, so that the power supplied to the electronic apparatus can be cut off by transmitting the relay cutoff signal to the corresponding relay.

If the individual maximum reference power and the integrated maximum reference power are stored in the memory 220, the auxiliary controller 230 determines whether each of the load powers detected by the plurality of first detectors exceeds the individual maximum reference power, Even when the load power exceeds the individual maximum reference power, the power supply to the electronic device can be cut off by transmitting the relay cutoff signal to the corresponding relay. That is, the overcurrent and the overvoltage are prevented from being applied. If the total sum of the load powers detected by the plurality of first detectors exceeds the integrated maximum reference power, and if the sum of the load powers exceeds the integrated maximum reference power, at least one of the plurality of relays outputs the relay cut- So that the power supplied to the electronic device can be cut off. That is, it is possible to prevent an electric fire from occurring due to occurrence of an overcurrent, a short circuit, a spark, a short circuit, and the like.

Then, the auxiliary controller 230 transmits the load detection signal periodically (for example, 1 second) to the second detector corresponding to the relay to which the relay shutoff signal has been transmitted.

The relay unit 50 includes a plurality of relays RL and each of the plurality of relays RL responds to a relay shutoff signal applied from the auxiliary control unit 230 to an input power Thereby blocking the application to the corresponding electronic device LD.

The plurality of relays RL are connected in response to a reset signal output from a corresponding one of the plurality of second detectors so that the input power can be applied to the corresponding electronic device LD.

That is, each of the plurality of relays RL blocks the input power applied to the electronic device in response to the relay cutoff signal, and applies the input power cut off in response to the reset signal to the electronic device.

The second detection unit 212 is provided in the sensor unit 210 of FIG. 1 as well as the first detection unit 211 and includes a plurality of second detectors. Each of the plurality of second detectors 212 transmits And when the measured load resistance value is equal to or greater than a predetermined reference load resistance value, the reset signal is outputted to the corresponding relay (RL) To the electronic device.

Here, the reference load resistance value may be stored in each of the plurality of second detectors, or may be stored in the memory unit 220. In the above description, the second detector stores the reference load resistance value having a fixed resistance value. However, the reference load resistance value may also be calculated by the auxiliary controller 230 using the load power detected by the first detector, 220). In the present invention, the auxiliary controller 230 determines whether the electronic device is in the standby state or in the operating state, and the first detector measures the load power of the electronic device, The load resistance value can be calculated. Therefore, when the auxiliary controller 230 calculates the load resistance in the operating state of the electronic apparatus and stores the load resistance in the memory unit 220 as the reference load resistance, the reference load resistance variable that varies depending on the type and state of the connected electronic device .

Each of the plurality of second detectors may further include a switch for outputting a reset signal and at the same time for interrupting an electrical connection with the electronic device and then electrically connecting the electronic device when the corresponding relay is shut off again have. That is, each of the plurality of second detectors is electrically connected to the electronic device when the corresponding relay is turned on, and is electrically connected to the electronic device when the corresponding relay is turned off. This is because the second detector performs the operation only while the input power is not applied to the electronic device.

The auxiliary power source PW is a power source used by the plurality of second detectors of the second detection unit 212 to sense the load resistance value of the electronic device. In the present invention, the second detector measures the load resistance value of the electronic device in a state in which the relay is shut off, i.e., the input power source IN is not supplied to the electronic device. Therefore, in order to measure the load resistance value of the electronic device, a separate power source to be supplied to the electronic device is required. Since it is a power source for simply measuring the magnitude of the load resistance value, applying a high voltage power source is a waste of power because it generates unnecessary power consumption. Therefore, in the present invention, the electric fire prediction system includes an auxiliary power source PW having a voltage level (for example, 5V) lower than the input power source IN so that the second detector can measure the magnitude of the load resistance of the electronic device. do. The auxiliary power source PW may be implemented as a battery or may be implemented as a transformer that receives the input power source IN to lower the voltage level.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.

Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
