[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic fire extinguisher which detects a fire and automatically extinguishes it.

[0002]

2. Description of the Related Art Conventionally, as such an automatic fire extinguisher,
There is a fire extinguisher in the garbage pit. The garbage pit is
This is for temporarily storing the garbage before incineration at the garbage incinerator, and the garbage carried in by the garbage truck is once stored in the garbage pit, and the stored garbage is transported to the incinerator by the crane device etc. To incinerate. Various kinds of dust are mixed in the dust pit, and in some cases, dust that is easily ignited or dust that is a direct ignition source is mixed. In addition, a chemical reaction may occur in the dust pit, resulting in a high temperature, which may cause a sudden fire in the dust pit.

A fire extinguishing device for a dust pit detects the occurrence of a fire and the position of the fire in the dust pit with an infrared camera or the like, and extinguishes the detected fire by a water gun or other extinguishing means. is there. Specifically, for example, by using an infrared camera, the surface temperature of dust stored in the dust pit is detected for each predetermined region, and the temperature of the arbitrary region is set to the predetermined temperature based on the detected temperature distribution in the dust pit. If the above is the case, it is considered that a fire has occurred in the area, and fire is extinguished by spraying water to this area with a water gun.

FIG. 12 is a diagram showing an example of a water discharge pattern by a water discharge gun. FIG. 12 (a) shows an example of a water discharge pattern from the side surface, and FIG. 12 (b) shows an example of a water discharge pattern from a plane. Three patterns of water discharge are shown, one for near water, one for distant water, and one for water in the middle. This water gun has a water discharge pattern as shown in FIGS. 12 (a) and 12 (b), and if the fire is fired from just above the dust pit by a two-dimensional plane, the height of the dust will increase. It can be seen that the water discharge position and the amount of water discharge change depending on. Therefore, by using the above-mentioned two infrared cameras and detecting the fire occurrence position by performing calculation based on the angle at which these cameras face the fire occurrence position, the dust height position at the fire occurrence position can also be detected at the same time, which is correct. It was supposed to spray water at the location of the fire.

That is, in the above-described automatic fire extinguisher, the two infrared cameras are directed toward the fire occurrence position in order to detect the dust height position, and arithmetic processing is performed based on the angle formed by these cameras to perform the fire occurrence position. Since the dust height position in the above was detected, an arithmetic circuit for obtaining the dust height position is required, and since two infrared cameras are also required,
There is a problem that the cost becomes high. In addition, since it requires a calculation time for obtaining the dust height position,
There was a problem that the position control of the water gun was delayed. Further, when a fire or the like causes smoke or the like and the position where the fire is generated cannot be detected by the infrared camera, there is a problem that the dust height position at the position where the fire is generated cannot be obtained.

The display unit 8 visually notifies various information to the outside. It is a thing.

Next, the operation of this embodiment will be described. 6 and 7 are flowcharts of the automatic control process of this embodiment. In the following description, S indicates a processing step. First, the fire detection device 3 checks whether or not a fire has occurred (S1), and when a fire is detected, the fire prevention output from the disaster prevention system in the monitoring room S is performed, and the display 8 indicates that a fire has occurred. Is displayed (S2).
Then, it is checked whether or not the fire extinguishing pump P has started operating (S3), and when the start of the fire extinguishing pump P is confirmed, an operation command is output to the fire extinguishing pump P (S4).

Here, it is checked whether the operation mode in the disaster prevention system is the automatic mode or the manual mode (S5). If the operation mode is the manual mode, the manual control process described later is executed (S6), and the automatic mode is set. If there is, it is checked whether or not it is ready to receive the fire position and height data (S7). When ready to receive data, the water gun control unit 6 receives the data of the fire occurrence position (any one of the 98 regions described above) from the fire detection device 3. Then, the height data (any of the four blocks) corresponding to the data of the fire occurrence position is received from the data storage unit 5, and the fire position and the height data are displayed on the display unit 8 (S8).

Next, based on the input data of the fire occurrence position, it is checked whether or not the fire occurrence position is the water discharge target section by the B water gun (S9), and if it is not the water discharge target section by the B water gun. Determines that it is the water discharge target section by the A water spray gun, and controls the aiming of the A water spray gun by the aiming control unit 6a (S10). On the other hand, in the determination process of S9, when the fire occurrence position is the water spray target section by the B water spray gun, an instruction to open the door provided in front of the B water spray gun is issued (S11), and aiming control is performed when the door is completely opened. Aiming control of the B water spray gun is performed by the unit 6a (S12, S13). Then, during the aiming control by the aiming control unit 6a, a display indicating that the aiming is being performed is displayed on the display unit 8 (S14).

When the aiming is completed (S15), the display unit 8 becomes a water discharge standby display (S16), and the time counting by the timer unit 6c is started (S17). Then, the timer unit 6c checks whether or not the time measurement for 5 minutes has ended (S1).
8) When finished, a time-up signal is output to the main controller 6d. Also, it is checked whether or not there is an evacuation completion signal that informs the evacuation completion of the crane device T from the crane control unit 4 (S
19) When the evacuation completion signal is input from the crane control unit 4 to the main control unit 6d, the display unit 8 displays that water is being prepared (S20). Next, it is checked whether the water gun 2 to be used is an A water gun or a B water gun (S2
1) When using the A water spray gun, the automatic valve of the A water spray gun is opened (S22), and when using the B water spray gun, the automatic valve of the B water spray gun is opened (S23). When the automatic valve is opened, it is checked whether or not the pressure switch is turned on (S24), and if it is turned on, it is determined that the water discharge by the water spray gun 2 has started, and the display section 8 indicates that the water is being automatically discharged. A message to that effect is displayed (S25), and the process waits for interrupt processing.

FIG. 8 is a flowchart of the manual control process of this embodiment. In the manual control process, first, the automatic aiming control of the water spray gun 2 is stopped (S31), and the three water spray guns A to C are stopped.
Select which water gun 2 to use (S)
32). Here, it is checked whether or not the B water spray gun is selected (S33), and if the B water spray gun is selected in this determination process, whether or not the door provided on the front surface of the B water spray gun is opened. A check is performed (S34), and when the door is not open, a door opening command is issued to open the door (S35,
S36).

Next, a manual operation is selected (S37),
Here, when the joystick operation is selected, a message indicating that the aim is being made is displayed on the display unit 8 (S38),
By operating the joystick 7b corresponding to the selected water spray gun 2, aiming control of the water spray gun 2 selected in the process of S32 is performed (S39). Then, the manual control process is executed again (S40). Further, in the selection process of S37, when the water discharge operation is selected, the display unit 8 displays that the water discharge is being prepared (S41) and opens the automatic valve of the water discharge gun 2 selected in the process of S32. (S42). When the automatic valve is opened, it is checked whether or not the pressure switch is turned on (S43), and if it is turned on, it is considered that the water discharge by the water spray gun 2 has started, and the display unit 8 is manually discharged. A message to that effect is displayed (S44), and the manual control process is executed again (S45). Further, in the selection process of S37, when the water discharge stopping operation is selected, the automatic valve of the target water gun 2 is closed (S46), and the manual control process is executed again (S47). When exiting this processing, the operation mode is switched to the automatic mode by executing the automatic / manual switching interrupt processing described later.

FIG. 9 is a flow chart of the automatic / manual switching interrupt processing of this embodiment. The automatic / manual switching interrupt process switches a preset operation mode by an interrupt process. When the operation mode is switched, it is determined whether the switched current operation mode is the automatic mode or the manual mode. If it is checked (S51), it is in the manual mode, the above-mentioned manual control process is executed (S52), and if it is in the automatic mode, the fire detection device 3 checks whether or not a fire has occurred (S53), and a fire has occurred. 6 is detected in order to perform aiming control,
On the other hand, when the fire does not occur, the process waits for interrupt processing.

FIG. 10 and FIG. 11 are flowcharts of the restoration interrupt processing of this embodiment. In the recovery interrupt processing,
First, it is checked whether the current operation mode is the automatic mode or the manual mode (S61). If the current operation mode is the manual mode, the above-mentioned manual control process is executed and the recovery process is not executed (S62). That is, this restoration process is a process performed on the A water spray gun and the B water spray gun.
A process of storing the water spray gun and the B water spray gun in predetermined positions and a process of closing the door of the B water spray gun are performed. Further, since the C water spray gun operates manually, the water discharge stop, that is, the recovery operation is also manually performed.

Next, the fire detection device 3 checks whether or not a fire has occurred (S63). If a fire is detected, it is determined that the fire is continuing and recovery processing is not performed. Proceed to the process of S7 to read the fire position / height data again and continue water discharge. This is because a fire may have occurred at a position different from the previous fire occurrence position. When the fire is extinguished in the determination process of S63, whether the water spray gun 2 used for water spray is the A water spray gun, the B water spray gun, or the A water spray gun and the B water spray gun.
It is checked whether or not both are water spray guns (S64), and the corresponding automatic valve of the water spray gun 2 is closed (S65, S6).
6, S67), and the display 8 indicates that the recovery is in progress (S68).

When the automatic valve is closed, it is checked whether or not the pressure switch is off (S69). If it is off, it is assumed that the water discharge by the water spray gun 2 has been stopped, and it is used again for water discharge. Whether the water gun 2 is an A water gun,
It is checked whether it is the B water spray gun or both the A water spray gun and the B water spray gun (S70), and the corresponding water spray gun 2 is stored (S71, S72, S73). Then, it is checked whether or not the water gun 2 is completely stored (S7).
4) After confirming the storage completion, it is then checked whether or not the B water spray gun is used (S75). Here, when the B water spray gun is used, a closing command is issued to the front door of the B water spray gun to close the door (S76, S77). That is, when a fire occurrence signal indicating that a fire has occurred in the dust pit 10 is input to the water gun control unit 6 from the fire detection device 3, the water gun control unit 6 stores height data for the fire occurrence position in the data storage unit. It is possible to read from 5 and aim the water gun 2 at the correct fire occurrence position.

As described above, in the present embodiment, it is possible to monitor fire with one infrared sensor 3a, and to detect the loading height of dust with high accuracy using the crane device T provided in advance. You can Furthermore, since a calculation circuit for specifying the fire occurrence position when a fire occurs is not necessary, the system can be constructed at low cost. In the above-described embodiment, the inside of the dust pit 10 is 98 × 7 × 14.
Further, the height direction is divided into four steps and managed, but the number of divisions can be arbitrarily set according to the accuracy of the fire detection device 3, the water discharge pattern of the water gun 2, and the like.

Further, in the above embodiment, as a method for detecting the height of the dust loaded in the dust pit 10, the gripping portion of the crane device T is lowered to the dust upper surface for each area divided into 98, and the gripping portion at that time is Based on position, in other words,
Although the stacking height of dust is detected based on the length of the wound wire cable, for example, the following method may be adopted. That is, since the dust thrown into the dust pit 10 from the throwing stage 11 is brought to the incinerator 13 side by the crane device T and then thrown into the throw-in hopper 12, when the crane device T grips the dust. Based on the height position of the grip portion, specifically, the winding amount of the wire cable (the length calculated from the motor speed of the winding machine), the height of dust near the lower position of the loading stage 11 is detected, while For the area of, the height of the dust may be detected based on the number of times the crane device T has dropped the dust and the height position of the gripping portion when the dust is gripped.

In this case, for example, when the dust is dropped in the same area after the dust is gripped and conveyed, based on the height position of the gripping portion holding the dust and the number of subsequent drops of dust, then The height position of the dust is required. Further, in the present embodiment, the stacking height of dust may be obtained by using the above method together. In addition, in the present embodiment, the height of dust as a deposit is detected by using the crane device T, but the present invention is not limited to this.
For example, a laser rangefinder or a zoom camera is used to calculate the height based on the focus point on the target image and the zoom ratio when the target image has a predetermined image size,
This calculated value may be stored in a data storage means such as a RAM.

In the above embodiment, the fire detection device 3
Although the infrared sensor 3a has been described as an example, the present invention is not limited to this, and a sensor such as a photoelectric separation type sensor may be arranged on a matrix to detect a fire.

[0033]

As is apparent from the above description, according to the present invention, the loading height data of dust in the dust pit can be surely grasped, and when a fire occurs, the height data at the fire occurrence point can be obtained. Can be identified quickly. Therefore, when water is discharged by the fire extinguishing nozzle, it is possible to accurately aim at the fire source position, water can be accurately discharged to the fire source position, and efficient fire extinguishing can be performed.
