[Industrial application] The present invention relates to a gas-based fire extinguishing equipment for automatically or manually operating equipment for a fire extinguishing object or a fire extinguishing object, and extinguishing fire when starting the fire extinguishing equipment. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a starter having certainty of gas release and safety measures against fire gas release due to erroneous operation.

[0002]

2. Description of the Prior Art Matters Concerning the First Invention Fire extinguishing equipment is equipment that is rarely used on a daily basis, and most operators currently do not know how to operate a starter. is there. For this reason, it is legally obligatory to provide a section name / operation method description name plate, a handling caution name plate, or the like at or near the activation device. However, the situation in which the equipment is used is in a special situation such as a fire, and the psychology of the operator is not always maintained.In such a situation, correct operation can be performed according to the operation explanation name plate etc. It is difficult and has always been associated with the risk of incorrect operation. In order to solve such problems, if you try to express detailed operating instructions according to various situations with a caution name plate, etc., it will be a huge amount of explanation text and will be completely useful in the event of an emergency of fire. There is a problem that not only can it be hit, but on the contrary, it may hinder prompt fire fighting.

In order to solve these problems, an explanation of voice operation according to each situation has been devised.
Status of each compartment, status of equipment, etc. (sensor operating status,
Explaining the operation method together with the explanation of automatic and manual conditions of the equipment, manned in the compartment, unmanned etc. is time-consuming to explain, so it is against the purpose of extinguishing the fire early Moreover, the operator may operate the operation without waiting for the explanation to be finished, which may lead to an erroneous operation. Also, the audio explanation is transitive, and it is effective for short ones,
As mentioned above, if a large amount of information is explained, it is possible to make a mistake in listening. Further, even if the user tries to operate according to the description of the operation method by voice, the actual switch is not known, and thus there is a possibility that an erroneous operation is performed. In addition, many of the fire extinguishing equipment have a structure that delays the release of the extinguishing agent by 20 seconds or more after being activated by the operation of the activation device, and the activation is canceled within this delay time. An emergency stop switch is installed adjacent to the start switch so that you can operate the start switch by mistake, or operate the emergency stop switch normally. Regardless, since the fire extinguishing agent is not released during the delay time, it is possible that the operator mistakenly operates the operation method incorrectly and operates the nearest emergency stop switch, which may cause the equipment to be deactivated. there were. Furthermore, since it is a facility that is not generally known, if the startup device is operated by mistake with other general equipment, or if the startup device is operated by mischief, etc., as long as it is within the delay time as described above. Since there was no proper explanation of where the extinguishing agent could be stopped by the emergency stop switch, the extinguishing agent was released as it was, and there was a risk of injury.

For the above reasons, the situation of each compartment,
There has been a demand for a start-up device that has a display unit that displays the status of equipment and the like, and that also has a brief operation explanation according to each status. Also, in most gas fire extinguishing equipment, an automatic circuit that starts in conjunction with the operation of the fire detector,
A manual circuit to be activated can be selected by operating the discharge switch of the activation device, and the switching of these circuits cannot be easily performed without a key or the like. However, it may not be possible to switch due to the loss of the key, etc., and the key storage management state is bad, and it is not possible to switch quickly in an emergency, so if the equipment is in the automatic state at the time of fire, for example, it is easy to partition. There was a possibility that I could not confirm the condition inside. Also,
On the other hand, anyone with a key can switch between the automatic and manual circuits, so the person who switched can not be identified, and it is difficult to clarify the responsibility in the event of an accident. Furthermore, in the automatic circuit, the extinguishing agent is released in conjunction with the operation of the detector.For example, if the fire detector is operating for some reason in the manual circuit, the fire will be released in this state. Extinguishing media is released when switching from a manual circuit to an automatic circuit without restoring the sensor. Therefore,
In the case of assuming manual / automatic switching in such a state, there is a problem in that management with a key or the like is not sufficient and may lead to personal injury.

One of the major features of the gas-based fire extinguishing equipment is that there is no water loss or the like after the fire is extinguished in the fire section and the section can be quickly restored. Especially in computer rooms, electric rooms, etc., the longer the equipment is down, the greater the damage. Therefore, most of these compartments use gas fire extinguishing equipment which is characterized by quick recovery. However, even if the fire extinguishing equipment with such features is adopted, it will take time and effort to confirm extinguishing the fire or to confirm whether or not a person can enter the compartment after the extinguishant has been discharged. The current situation is that the features of are not utilized effectively.

As a current method for confirming extinguishing, a method in which a person attaches an air respirator to the room and directly confirms it, or a method of confirming by restoring the fire detector is adopted.
If a person enters the room and confirms it directly, it is very dangerous because smoke from a fire causes poor visibility, and when confirming by restoring the fire sensor, the fire sensor may have failed due to the heat of the fire. Yes, the reliability of the equipment is low, and it is extremely difficult to use in any case, so it is most certain to enter the room and check the fire extinguishing after exhausting smoke, fire extinguishing agents, etc. in the compartment. In the case of gas-based fire extinguishing equipment, discharging the extinguishing agent in a non-extinguishing state can cause a fire to spread and is extremely dangerous. Therefore, it is necessary to leave it for a while. Such leaving for a long time not only delays the restoration of the equipment, but also decomposed products at the time of a fire may adversely affect even equipment that is not directly damaged by the fire due to corrosion or the like. Furthermore, even if the fire is extinguished by some method and smoke, fire extinguishing agents, etc. in the compartment are discharged, in order to confirm whether a person can enter the compartment,
Special equipment such as temperature sensor, gas sensor, oxygen concentration sensor is required, and these are generally not prepared and it takes time to prepare, or temperature distribution, gas concentration distribution, oxygen Since the concentration distributions are different, it is still necessary for a person to attach an air respirator or the like to measure each point in the compartment, which poses a problem such as danger.

Matters relating to the second invention Most gas-based fire extinguishing equipment is constructed so that the fire extinguishing agent container is shared and a fire extinguishing agent is selected and the fire extinguishing agent is released. Despite that the compartment nameplate is attached to the compartment, both compartments will operate if the fire compartment starter is operated again after operating the starter in another compartment by mistake. The fire extinguishing agent was not supplied to the fire compartment and there was a risk of extinguishing the fire. In addition, the fire extinguisher equipment,
It has a structure that delays 20 seconds or more until the fire extinguishing agent is released after starting by operating the starter.
Within this time, the activation can be stopped by operating the emergency stop switch built into the operated activation device. However, in the above example, after operating the starter of another compartment by mistake, even if you notice an error when operating the starter of the fire compartment, in order to stop the startup,
There was a problem in that it had to be returned to the position of the starting device that was operated first, which was virtually impossible, resulting in erroneous discharge.

Items Concerning the Third Invention Although the gas-based fire extinguishing agent facility has an advantage that there is no water loss after extinguishing fire, for example, in the case of carbon dioxide, if the fire extinguishing agent is released to a section where a person is present, it will cause oxygen deficiency. There is a possibility of personal injury, and in the case of halogen powder, the sound of fire extinguishing agent may make you surprised and may flood into the emergency exit. In order to solve this problem, there is a device that manages the entry / exit of a person to / from a compartment (by a person sensor, a bar switch, etc.) and does not start even if an activation device is operated. If it is judged to be manned, the structure is such that not only the automatic circuit but also the manual circuit is prohibited. Therefore, it is premised that there is no malfunction or failure of the human body sensor, etc.
As long as there are malfunctions and failures in human body sensors, there is a problem that fire extinguishing activities cannot be performed by the fire extinguishing equipment. In addition, even when a person is present in the compartment, when the human body sensor or the like determines that the person is unattended (for example, when the human body sensor is in the shadow of the person, the human body sensor is not sensed, the bar switch can simultaneously enter two persons, etc.), There is a problem that the extinguishing agent may be released.

[0009]

[Means for Solving the Problems] The first invention of the present application is
Operation until the fire extinguishing equipment is operated by configuring the operating part of the starter in the gas fire extinguishing equipment with a display device with a switch function that makes the display screen of the display device multi-layered and interactive by microcomputer control. The procedure of is specified by microcomputer control. In the second invention of the present application, the operating unit is configured by a display device with a switch function that multi-layers the display screen of the display device by a microcomputer control and makes it interactive, and operates the activation device of any target section. If the startup device of another target compartment is operated before the extinguishing agent is released, the fact that there is an already operating fire extinguishing compartment on the display screen of the display device is displayed by the microcomputer control. At the same time, an emergency stop switch for stopping the operation of all circuits in response to a malfunction is displayed on the display screen of the display device. In the third invention of the present application, the presence of a person on the screen is displayed on the display screen in conjunction with the operation of the sensor that recognizes the presence of a person in the fire extinguishing compartment, and the activation circuit is linked with the fire detector. In the case of the automatic release that operates in the above manner, the manual release is forcibly switched to and the manual release is displayed on the screen on the display screen of the display device.
