Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster prevention / crime prevention system constructed such that a disaster prevention system and a crime prevention system are interlocked with each other.

[0002]

2. Description of the Related Art A disaster prevention / crime prevention system is a system for wide-area monitoring of a large-scale building such as a tenant building. The disaster prevention / crime prevention system is configured, for example, as shown in FIG. That is, the disaster prevention terminal 8 including a plurality of detectors such as smoke detectors and heat detectors, the crime prevention terminal 16 such as a crime prevention sensor, the lighting control panel 14 to which the lighting means 23 is connected, and the air conditioner 22 are provided. A partition facility 21 including the connected air conditioning control panel 13 and the like is installed in each partition in the building, and all of the partition facility 21 are the central monitoring device 2 in the monitoring room.
0 is connected to the signal line.

The disaster prevention terminal 8 is connected to the disaster prevention receiver 3 incorporated in the central monitoring device 20 by a signal line. Each sensor constituting the disaster prevention terminal 8 is
The environmental conditions such as the smoke density and the temperature change amount in the section where is installed are sensed, and the environmental condition data indicating the analog level of the environmental conditions is output as an encoded signal.
In the disaster prevention receiver 3, a fire occurrence reference value for judging a fire occurrence by comparison with the environmental condition data is set for each sensor, and a disaster prevention terminal 8 provided in each section is configured. The signal indicating the environmental condition data is sequentially received from each sensor, and the analog level of the environmental condition data obtained from a certain sensor exceeds the fire occurrence reference value set for the sensor. Sometimes, it is judged that there is a fire in that section. The fire occurrence reference values for all the detectors are set in the disaster prevention receiver 3, and the most appropriate values obtained by experimental simulation are set.

When the disaster prevention receiver 3 determines that a fire has occurred based on the environmental condition data from the disaster prevention terminal 8, it closes the fire doors and shutters and opens the emergency door. There is. The fireproof damper of the air conditioner 22 is closed to block the conditioned air, and the smoke exhaust port is opened to discharge fire smoke outside the building. In addition, fire extinguishing equipment may be activated, and guide lights installed in various parts of the building may be selectively turned on to guide the evacuation route according to the fire situation, depending on which section the fire is originating from. It is possible.

The crime prevention terminal 16 is connected to the crime prevention receiver 4 incorporated in the central monitoring device 20 by a signal line. The security terminal 16 is composed of an entrance / exit management device for centrally managing the locked / unlocked state of the doors of each section and the entry / exit status of a person entering / exiting each section, a security sensor for detecting an illegal intruder, and the like.

The security monitoring level for each section by the security terminal 16 and the security receiver 4 changes depending on whether a certain section is in normal business or closed. That is, when the compartment is closed due to a holiday or at night, and when the access door of the particular compartment is confirmed to be locked by the entrance / exit management device, the security receiver 4 detects the security sensor. The sensitivity is set to be more sensitive than that in normal business, and the crime prevention monitoring level is strengthened to put the section in a warning state.

Further, the crime prevention receiver 4 is adapted to interlock with the disaster prevention receiver 3. That is, when the disaster prevention receiver 3 determines that a fire has occurred, the crime prevention receiver 4
Various doors inside the building such as emergency doors are automatically unlocked so that they can be opened and closed.

[0008]

Generally, in a building such as a tenant building, at the time of normal business when people move actively, unlike the time when people are absent, the amount of dust and dirt in the air increases and air conditioning is performed. The temperature is different from that when the machine is closed because the machine 22 operates. Therefore, in the conventional configuration, for example, when the detection sensitivity of the disaster prevention terminal 16 is set according to the monitoring system at the time of holiday, dust, dust, cigarette smoke, warming of the temperature due to the operation of the air conditioner 22 and the like during normal business are performed. If the disaster prevention receiver 3 determines that a fire has occurred for a cause other than a fire, or conversely, if the detection sensitivity is set according to the monitoring system during normal business, the disaster prevention receiver will receive even if a small fire occurs during the holidays. No. 3 did not judge that a fire had occurred, and so-called fire misinformation was apt to occur.

The reference value of fire occurrence of the disaster prevention terminal 8 is
It is common to set a so-called general value obtained by simulating on the manufacturer side before the product of the disaster prevention terminal 8 is shipped, but since the environmental conditions of each section in the building are different in all of them, In order to perform accurate disaster prevention management and prompt response to a fire, it is necessary to install the disaster prevention terminal 8 in which the fire occurrence reference value suitable for each section is set. However,
Since it is very difficult to experimentally simulate each section and obtain the appropriate fire occurrence reference value for each section, accurate disaster management for each section and prompt response to a fire There was a certain limit to what I could do.

The present invention has been made to solve the above problems, and an object of the present invention is to provide prompt and reliable disaster prevention management in which a false alarm is unlikely to occur in a section in which a disaster prevention terminal is installed. In addition, it is possible to provide a disaster prevention / crime prevention system capable of creating an optimum disaster prevention management system for the division according to the environmental condition of the division and the crime prevention monitoring level.

[0011]

In order to solve the above-mentioned problems, the present invention provides a crime prevention means for crime prevention monitoring in a compartment, environmental condition data indicating an environmental condition in the compartment, and criteria for determining a fire occurrence in the compartment. In a disaster prevention / crime prevention system comprising a disaster prevention means for judging whether or not a fire has occurred by comparing it with a fire occurrence reference value, the fire occurrence reference value is used as a crime prevention monitoring level within a section in the crime prevention means, and the section. It is characterized in that the setting is changed based on the history of the environmental condition data of 1.

[0012]

According to the present invention, the fire occurrence reference value for the disaster prevention means is changed based on the crime prevention monitoring level in the compartment in the crime prevention means and the history of environmental condition data in the past detected by the disaster prevention means. It

The present invention will be described below with reference to the drawings showing its embodiments.

1 and 2 are block diagrams showing an embodiment according to the present invention. In FIG. 1, reference numeral 2 denotes a crime prevention means 2 for crime prevention management. The crime prevention means 2 includes a crime prevention terminal 16 including the entrance / exit management device 11 and the crime prevention sensor 9, a control unit 12 including an air conditioning control panel 13 and a lighting control panel 14, and the crime prevention module 12. The security receiver 4 is configured to receive and process information signals from the terminal 16 and the control unit 12. However, the security terminal 16 often includes a plurality of the entry / exit management devices 11 and a plurality of security sensors 9. The crime prevention terminal 16 is installed in each section of the building as in the conventional example.
Further, the control unit 12 may collectively control the entire building, or as shown in FIG. 2, it may be installed on each floor of the building and may control each floor.

In the security means 2 described above, when the entry / exit management device 11 confirms that the access door of the section in which the entry / exit management device 11 is installed is locked, the access door of the section is locked. Is sent to the security receiver 4. When the security receiver 4 receives the signal output indicating the locked state of the entry / exit management device 11, the security receiver 9 resets the sensitivity of the security sensor 9 to a sensitivity that is higher than before, and monitors the section. Strengthen the level and put the parcel in vigilance.
At the same time, the security receiver 4 sends a signal indicating the warning state of the section (hereinafter referred to as "warning signal") to the disaster prevention receiver 3. Further, on the contrary, when the entry / exit management device 11 is confirmed to unlock the common door of the compartment,
A signal indicating the unlocked state of the universal door of the section is sent to the security receiver 4. When the security receiver 4 receives a signal output indicating the unlocked state of the entrance / exit management device 11, the security sensor 9 resets the sensing sensitivity of the security sensor 9 to a sensitivity that is less sensitive than before, and the crime prevention for the section is performed. Decrease the surveillance level and leave the compartment in a non-warning state. At the same time, the security receiver 4 sends a signal indicating the non-warning state of the section (hereinafter referred to as "non-warning signal") to the disaster prevention receiver 3.

Reference numeral 1 is a disaster prevention means 1 for disaster prevention management.
Is. The disaster prevention means 1 comprises a disaster prevention terminal including various sensors 6 such as smoke detectors and heat detectors, and a disaster prevention receiver 3 for receiving and processing information from the disaster prevention terminal 8.
As shown in FIG. 2, the disaster prevention terminal 8 is installed in each section of the building.

The disaster prevention terminal 8 senses environmental conditions such as smoke density and temperature change in a certain section in which the disaster prevention terminal 8 is installed, and encodes environmental condition data indicating an analog level of the environmental condition as a coded signal. Is output as. In the present specification, the "smoke concentration" refers to not only the concentration of fire smoke in the air, but also the concentration of air such as dust, dust, and cigarette smoke. In addition, the disaster prevention terminal 8 often includes a plurality of each of the sensors 6 described above. In this case, a plurality of sensors 6 each having a unique address are fed and wired by two wires, and an addressing signal is sent from the disaster prevention receiver 3 to each of the sensors 6 via the wires, At that time, only the sensor 6 having the address designated by the address designation signal sends the signal indicating the environmental condition data to the disaster prevention receiver 3.

In the disaster prevention receiver 3, a fire occurrence reference value for judging a fire occurrence by comparing with the environmental condition data is individually set for each of the plurality of detectors 6, and further, each detection is performed. Different fire occurrence reference values are received for each device 6 when the warning signal output from the security receiver 4 is received and when the non-warning signal output from the security receiver 4 is received. Is set to. Normally, the fire occurrence reference value for when the warning signal is received is set to a lower value. The disaster prevention receiver 3 receives a signal indicating the environmental condition data from the sensor 6 of the disaster prevention terminal 8 installed in the section, and further receives the crime prevention from the two fire occurrence reference values given to the sensor 6. One fire outbreak reference value is selected depending on whether a warning signal or a non-warning signal is received from the machine 4, and when the analog level of the environmental condition data exceeds the fire outbreak reference value, the section Judge that a fire has occurred. The process is sequentially performed for each sensor 6 of the disaster prevention terminal 8.

The disaster prevention receiver 3 receives the warning signal for the environmental condition data read from a certain sensor 6, and thereafter receives the environmental condition data (hereinafter, referred to as "warning environmental condition data") and the environmental condition data. The non-warning signal is received and classified into subsequent environmental condition data (hereinafter referred to as "non-warning environmental condition data") to be accumulated for a certain period of time. The group of environmental condition data at the time of warning and the group of environmental condition data at the time of non-warning are separately analyzed by taking into account the previous environmental condition data, respectively, and the environmental condition at the time of the warning within the next fixed period. The fire occurrence reference value for the data and the fire occurrence reference value for the non-warning time environmental condition data within the next fixed period are reset. The disaster prevention receiver 3 sequentially performs this process for each sensor 6.

Further, the disaster prevention receiver 3 is designed to work with the crime prevention receiver 4 and the air conditioning control panel 13 as in the conventional case. That is, when the disaster prevention receiver 3 determines that a fire has occurred in a certain section based on the environmental condition data from the disaster prevention terminal 8, it closes the fire doors and shutters of the section and opens the emergency door. It is designed to open the door.
In addition, the fire damper of the air conditioner 22 is closed to block the conditioned air, and the smoke outlet is opened to discharge the fire smoke to the outside of the building. In addition, fire extinguishing equipment may be activated, and guide lights installed in various parts of the building may be selectively turned on to guide the evacuation route according to the fire situation, depending on which section the fire is originating from. It is possible.

Next, the operating state of the disaster prevention / crime prevention system will be described. FIG. 3 is a diagram showing an operating state of the disaster prevention / crime prevention system in the embodiment of the present invention. As an example, FIG. 3 is a graph of the smoke detection status of the smoke detector, in which the vertical axis represents smoke concentration and fire occurrence reference value, and the horizontal axis represents time. The same applies to the heat sensor.

For a certain section, the normal business state in which human movement is active is shown in FIG. 3 as periods 30b, 30d, 30.
f. At this time, the entry / exit management device 11 confirms that the universal door of the section is unlocked. In addition, the control unit 12 confirms the ON state of lighting and air conditioning. From the above data, the security receiver 4 determines that the section is normally open.

Further, the closed state in which no person is present in the section is periods 40b and 40d in FIG. At this time, the entry / exit management device 11 confirms that the universal door of the section is locked. Further, the control unit 12 confirms the off state of the lighting and air conditioning. From the above data, the security receiver 4 determines that the section is closed.

The fire occurrence reference value set in the disaster prevention receiver 3 is reset when the section shifts from the normal business state to the closed business state and when the section shifts from the closed business state to the normal business state.

First, FIG. 3 shows the operating state during normal business.
It will be explained based on. The fire occurrence reference value 30a in the period 30b is a level set based on the accumulated amount of smoke density data during normal business before the period 30b. First, in the period 30b, the security receiver 3 intermittently inputs the smoke density data indicating the smoke density of the section from the smoke sensor, and accumulates the smoke density data. And the period 3
Smoke density data 50a obtained at 0b (the smoke concentration data 50a, 50b, ... In FIG. 3 indicate the analog levels of a large number of smoke concentration data obtained over time as a graph curve) and before that. The fire occurrence reference value 30c in the period 30d, which is the next normal business time, is reset based on the smoke density data at the normal business time. Similarly, based on the smoke concentration data 50c in the period 30d and the smoke concentration data in the normal business before that, the fire occurrence reference value 30e in the period 30f, which is the next normal business, is generated.
Has been reset. Also, the period 30g in the period 30f
Is a period during which the level of the smoke density data 50e exceeds the level of the fire occurrence reference value of 30 g, and the period of 30 g
In the above, the disaster prevention receiver 3 determines that a fire has occurred in the section.

Next, the operating state during the holiday will be described with reference to FIG. Fire occurrence standard value 4 in period 40b
0a is a level set based on the accumulated amount of smoke density data at the time of suspension of work before the period 40b. First, in the period 40b, the security receiver 3 constantly inputs the smoke density data indicating the smoke density of the section from the smoke sensor, and accumulates the smoke density data. Then, based on the smoke concentration data 50b obtained during the period 40b and the smoke concentration data at the time of the holiday before that, the fire occurrence reference value 30c in the period 40d which is the next holiday is reset.

In addition to the fire occurrence reference value, which is the criterion for fire occurrence, the fire prediction reference value, which is the criterion for fire prediction, may be set lower than the fire occurrence reference value. By comparing the fire forecast reference value with the environmental condition data, it is possible to give a forecast about the fire. The fire forecast reference value can be set and changed in the same manner as the fire occurrence reference value.

[0028]

As described above, according to the present invention, the crime prevention means for crime prevention monitoring in the compartment, the environmental condition data indicating the environmental condition in the compartment and the fire occurrence reference value which is the criterion for the fire occurrence in the compartment are provided. In a disaster prevention / crime prevention system comprising a disaster prevention means for judging whether or not a fire has occurred by comparison, in the fire occurrence reference value, the crime prevention monitoring level in the compartment in the crime prevention means and the environmental condition data of the compartment The setting is changed based on the history, and the disaster prevention is based on the crime prevention monitoring level in the section in the crime prevention means and the history of environmental condition data in the past of the section detected by the disaster prevention means. Since the fire occurrence reference value for the means is set and changed, quick and reliable disaster prevention management that is unlikely to cause false alarms can be performed for the section where the disaster prevention terminal is installed. Also, depending on environmental conditions and security monitoring level of installed are partitioned disaster prevention terminal, it is possible to produce optimal disaster management system in the compartment.
