Description

Auto-remote testing method and fire alarm device for detector of fire fighting system

The present invention relates to a method and apparatus for remotely checking a fire detector.

Due to the recent increase in the size and size of buildings, it can lead to enormous casualties in case of fire. Specific firefighting targets are to be operated at least once a year for functional function checks and comprehensive inspections. Recently, fire safety managers and related personnel are concerned about safety. In addition to a comprehensive overhaul, he is also watching to see if the fire protection system of the fire objects he manages is working properly.

As a fire-fighting facility, a fire detection system is established to detect fires and issue alarms. In order to prevent a great damage to the fire that can occur unexpectedly inside various buildings such as business, residential, etc., a fire detector is installed to detect whether a fire has occurred on the ceiling, and receives a fire detection signal from the fire detector. A fire receiver is provided which issues an alarm.

In general, a fire detector for detecting a fire includes a smoke detector for detecting smoke generated by a fire and a smoke detector for detecting heat. These fire detectors are usually located on the ceilings of living rooms / rooms or offices.In order to check whether the fire detectors are operating properly, individual inspections are performed by directly applying heat or smoke to each detector using an inspection mechanism. .

However, it is not only cumbersome to carry out the inspection by bringing the inspection equipment up to the ceiling, but dangerous situations can occur when the ceiling is high, and when inspecting the fire detector installed in the bedroom of the home, the inspector enters the bedroom and performs the inspection. This can lead to difficult situations due to privacy violations.

Although the description is omitted, it is obvious that a plurality of embodiments may be reimplemented into one integrated embodiment.

In addition, in the description with reference to the accompanying drawings, the same components regardless of reference numerals will be given the same or related reference numerals and redundant description thereof will be omitted. In the following description of the present invention, when it is determined that the detailed description of the related known technology may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a schematic view showing a general fire system.

The fire system includes a plurality of fire detectors (collectively referred to as 10-1, 10-2, ..., 10-n, hereinafter 10) such as smoke detectors and heat detectors, and a fire receiver 30 coupled through a network.

When the fire detector 10 detects smoke or heat generated by the fire, the fire detector 30 notifies the fire receiver 30, and the fire receiver 30 outputs an alarm indicating that a fire has occurred.

In such a fire system, according to an example of the present invention, the fire receiver 30 checks a fire detector 10 located remotely, and checks whether each fire detector 10 is normally measuring a smoke concentration or temperature. To do. The checking method will be described later in detail with reference to the accompanying drawings.

The fire receiver 30 has information on a communication address assigned to each of the fire detectors 10, so that the fire detector 10 and its address through a network such as the Internet network or its own local network (LAN). Communication can be performed using. Communication between the fire receiver 30 and the fire detector 10 using a network will be apparent to those skilled in the art, and thus, further description thereof will be omitted.

According to this embodiment, there is no need for the inspector to move directly to the location of the fire detector 10 in order to inspect the fire detector 10.

2 is a view illustrating a grouping concept of a fire detector according to an embodiment of the present invention, and FIG. 3 is a block diagram illustrating a configuration of a fire detector remote checking apparatus according to an embodiment of the present invention.

Referring to FIG. 2, the fire detectors 10 may be grouped and managed according to the installation location (or environment). As shown in the drawing, the first group is a fire detector of 10-1 to 10-9, and the second group is It may be a fire detector of 10-10 to 10-m. For example, the underground parking lot and the first floor lobby have different environments such as temperature, humidity, and dust, so that fire detectors can be managed by groups such as the underground parking group and the first floor lobby group.

The fire detectors of each group may have different inspection methods or inspection environments, which will be described later.

Also, as shown in FIG. 2, virtual fire detectors 11-a, 11-b, 11-c, and 11-d, hereinafter referred to as virtual detectors, among fire detectors are set. The virtual detectors 11-a, 11-b, 11-c, and 11-d are not physically present but are logical fire detectors operated virtually by the fire receiver 30 (ie, the fire detector check device).

The virtual detector receives and stores a sensing value from the actual fire detectors 10. In particular, the virtual sensor acquires the sensing values from the fire detectors in a sequential or random order at a predetermined time interval (for example, 1 hour interval, etc.) and stores only the highest sensing value or the lowest sensing value. The virtual sensor storing the highest sensing value is called the first virtual sensor, and the virtual sensor storing the lowest sensing value is called the second virtual sensor.

For example, when the heat detectors 1 to 5 sense 20 degrees, 21 degrees, 22 degrees, 19 degrees, and 20 degrees, respectively, and are sequentially provided to the virtual sensors, the first virtual sensor has the highest values of 22 degrees and the second. The virtual sensor stores a very low value of 19 degrees. That is, in the case of the first virtual sensor, a value of 20 degrees is first received and stored from the heat sensor 1, and when a sensing value is received from the heat sensor 2, it is higher than the stored value (that is, 21 degrees is higher). This is a method of changing the received value to 21 degrees and storing it.

Therefore, even if the administrator checks only the stored value of the virtual detector, the administrator can recognize the overall range of sensing values of the fire detectors (difference between the highest and lowest virtual detectors).

Such a virtual sensor may be set by one pair (first and second virtual sensors) for each group as shown in the figure.

Referring to FIG. 3, which shows a configuration of a fire receiver 30 that performs a remote check for a fire detector, the fire receiver 30 includes an information acquisition unit 310, a storage unit 320, an output unit 330, and a fire receiver 30. Including the control unit 340, the control unit 340 may include a check performing unit 341 and the interface unit 342 according to the function.

The information acquisition unit 310 is for acquiring a sensing value from each fire detector. For example, when the information acquisition unit 310 is combined with a fire detector through a wired or wireless network, the information acquisition unit 310 may receive a sensing value through network communication. According to an example, the information acquisition unit 310 requests the sensing value to the fire detector 10, the fire detector 10 is the current sensing value (temperature value in the case of heat detector, smoke detector in response to the request) The smoke value (eg, a percentage value) is provided to the information acquisition unit 310 of the fire receiver 30.

The storage unit 320 is a physical storage medium that stores the sensing values of the fire detectors acquired by the information acquisition unit 310, and stores related information necessary for driving each functional unit of the control unit 340. In addition, the storage unit 320 stores the information value 311 (the highest value / lowest value among the values sequentially obtained from the fire detectors) by the virtual detector.

The output unit 330 outputs a result report for the remote check. The result report may be in the form of printed output or may be in the form of a document file such as an image or PDF. It also outputs an alarm if there is a problem fire detector as a result of the check. The alarm may be an alarm sound, or may be processed by transmitting a notification message to a manager terminal (not shown, but a mobile device or a PC held by the manager).

The control unit 340 performs overall control of each component, and performs a check by checking whether the acquired sensing value of each fire detector 10 is out of a set normal range.

The inspecting unit 341 of the controller 340 selects a fire detector having a sensing value outside the normal range as the abnormality detector. For example, in the case of a heat detector, if the normal range is 5 to 30 degrees, a fire detector having a sensing value of 35 degrees is selected as an abnormality detector. The controller 340 outputs an alarm through the output unit 330 when the abnormality detector is confirmed.

The interface unit 342 of the controller 340 provides an interface for allowing an administrator to set a regular inspection date.

According to the laws related to firefighting, regular inspections of fire-fighting facilities have to be carried out. In some cases, the manager unintentionally misses the inspection period. To solve this problem, according to the present embodiment, the manager may perform a regular inspection. If the date (date and time) is entered in advance, the fire receiver will automatically perform the regular inspection on the regular inspection date.

In addition to the regular inspection, the administrator may perform a self-test from time to time, and may set in advance a time point to perform the self-test also in a reservation scheme, and the interface unit 342 provides an interface for setting such a check schedule. Such an interface may be provided through a communication network through a web method or an application program method. Since this will be used in various fields will be apparent to those skilled in the art, more detailed description will be omitted.

The interface unit 342 may provide an interface for confirming the information value of the virtual sensor, which will be described later with reference to FIG. 7.

Hereinafter, the remote check method in the fire receiver will be described in detail.

4 is a flowchart illustrating a process of remotely detecting a fire detector according to an embodiment of the present invention, and FIG. 5 is a flowchart illustrating an occasional inspection process of a fire detector according to an embodiment of the present invention.

First, referring to FIG. 4, which shows a basic periodic inspection process, when the fire receiver recognizes that the set inspection date is set (S410), each sensing value of all fire detectors is acquired (S420).

Then, by selecting a fire detector having a sensing value that is outside the set normal range as an abnormality detector, the remote inspection is performed (S430).

While outputting a result report for the remote check, if there is an abnormality detection, the alarm process is performed so that the administrator recognizes for a detailed check (for example, on-site check, etc.) (S440).

That is, the periodic inspection is to check whether the sensing value is out of the normal range by obtaining each sensing value for all the fire detectors, and as described above, the fire detectors are managed in groups according to the installation location / environment, and each group The normal range of is set. For example, for heat detectors, the parking range can range from 3 to 20 degrees and the lobby group can range from 10 to 25 degrees.

In addition to the periodic inspections, the on-site inspections may be carried out only on some fire detectors in order to reduce the processing load.

Referring to FIG. 5, which illustrates a check process, when a fire receiver recognizes an execution time for an occasional inspection according to a preset standard (S510), a part of each group of managed fire detectors is selected as a population (S520). ). For example, two heat detectors and two smoke detectors are selected in the first group, three detectors are selected in the second group, and one detector is selected in the second group as the population.

The sensor detects a sensing value of the selected population as a target for inspection, and compares the sensing values of the acquired population with the normal range of the population (S530) to determine whether there is an abnormal value outside the normal range of the population (S540). . The population normal range is similar to the normal range of FIG. 4, but the range value may be different. For example, the normal range of the population used in the occasional inspection may be set to a smaller range than the normal range of the periodic inspection. The reason for this is that only a part of the fire detectors are inspected, so if a small population normal range is satisfied, the probability that a fire detector is actually broken may be lower.

If there is no outlier, success processing (that is, all fire detectors are processed normally) as a result of the occasional inspection, and the results of the occasional inspection (e.g., population information (detector identification information, etc.), sensing value information, execution date, etc.). ) And waits for the next occasional check (S550).

 On the contrary, if an abnormal value exists as a result of the determination in S540, a remote inspection of the entire fire detector is performed as in the regular inspection (S560). Here, according to an example, when the entire inspection is performed according to the occasional inspection result, the change of the currently set periodic inspection date is processed together. For example, if the regular inspection date is set every six months, and the entire inspection is performed with the current three months remaining, the next regular inspection date is changed to be delayed six months later.

6 is a flowchart illustrating an inspection process using a virtual sensor according to an embodiment of the present invention, and FIG. 7 is an exemplary view showing an interface screen on which virtual sensor information is displayed on a manager terminal according to an embodiment of the present invention. to be.

Referring to FIG. 6, the fire receiver drives the virtual detectors (S610). That is, the virtual detector acquires sensing values sequentially by sequentially or randomly selecting from the managed fire detectors at regular time intervals such as one day or one hour, and stores the largest value or the smallest value.

In this case, the fire receiver may provide a real time value of the virtual detector to the manager terminal, and the manager may check the value 700 of each virtual detector on an interface screen displayed on the manager terminal as shown in FIG. 7. It can be checked for each group (using the reference numeral 710 button), or can be checked at any time as desired (using the reference numeral 720 button).

Referring back to FIG. 6, the fire receiver 30 compares the values of the first virtual detector and the second virtual detector periodically or whenever a change of the values of the virtual detector occurs (S620), and the difference is a threshold value. It is determined whether or not it is abnormal (S630). That is, it is determined whether the difference between the highest sensing value and the lowest sensing value is greater than or equal to a preset threshold.

If the difference is greater than or equal to the threshold value, an on-the-spot check is performed immediately (S640). In other words, as a condition for performing the occasional inspection, the value of the virtual detector is used, that is, the difference in sensing values of the fire detectors is used. If the difference is large, then there is a high probability that there is an abnormal fire detector.

On the contrary, if it is less than the threshold value, S620 may be performed again when a preset time elapses or there is a change in the value of the virtual sensors. Alternatively, if the virtual detector sequentially receives sensing values from all the fire detectors and completes one cycle, the virtual detector is reset (S650) and proceeds to S610 to perform the next cycle. That is, the process of receiving the sensing values from the fire detectors sequentially and storing the maximum / minimum value again).

Here, although not shown in the drawing, if any of the virtual detectors having a value outside the normal range exists, regular inspection for all fire detectors may be performed immediately.

According to the present embodiment, using the virtual detector, the sensing values of a large number of managed fire detectors are acquired at a time interval sequentially one by one without acquiring at the same time, and the processing load is reduced by using only one sensing value. The storage space can also be significantly reduced, allowing you to perform periodic and continuous checks rather than checking more efficiently and on specific days. Accordingly, when a failure occurs in any of the fire detectors, it is possible to sort out the broken fire detectors more quickly even before performing a regular inspection.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art to which the present invention pertains without departing from the spirit and scope of the present invention as set forth in the claims below It will be appreciated that modifications and variations can be made.
