Description

Description: TECHNICAL FIELD The present invention relates to a gas station that supplies fuel such as gasoline to automobiles and the like.

[Conventional technology]

Since such gas stations handle highly flammable hazardous materials such as gasoline, it is necessary to give due consideration to fire safety measures. Therefore, it is necessary to give due consideration to the occurrence of disasters such as earthquakes.

Therefore, as a gas station equipped with disaster prevention equipment for these disasters, for example, a gas station disclosed in Japanese Patent Application Laid-Open No. 59-15097 has been proposed, in which a sensor is provided for each device of the gas station and the output is introduced into a computer. The output is used to operate disaster prevention equipment.Sensors include image sensors that detect fire and illegal intruders, earthquake sensors that detect earthquakes, leak sensors that detect oil leaks in the piping, etc. Using the output of each of these sensors, the computer works to notify the fire department, police, security company, or responsible person of the occurrence of a fire or illegal intrusion, activate a fire extinguisher, or refuel in the event of an earthquake. Is in a state of being unable to refuel.

On the other hand, in the urban area, buildings such as buildings are built on the premises in order to make effective use of land, the ground floor of this building is used as a gas station, and the upper floor is used as offices and houses. In such a case, especially in the event of a fire, there is a great risk of catastrophic failure, so complete fire prevention equipment is required. For example, as shown in JP-A-61-60495, a fire detector and a fire detector A gas station has been proposed that has a power-operated shielding device at the entrance and exit of the vehicle.

This means that when a fire occurs, the power supply of the refueling device is shut off to prevent oil spillage, an alarm is activated and an alarm is activated, a fire extinguisher is activated, and the doorway of the car is blocked by a water curtain with a shielding device. It shields.

[Problems to be solved by the invention]

However, in the prior art described above, Japanese Patent Application Laid-Open No. 59-15097 reports, displays, reports, and activates a fire extinguishing system for fires and other disasters, but does not shut off the power of the refueling system. In the event of a disaster, highly flammable hazardous materials such as gasoline were handled and the lubrication system, which could easily cause a major danger, was left untouched, which was not sufficient as a disaster prevention measure.

On the other hand, Japanese Unexamined Patent Publication (Kokai) No. 61-60495 shuts off the power supply of the refueling system, but this is limited to the time of a fire and requires no consideration for other disasters such as earthquakes and oil leaks. They have not been paid, and this is not enough as a disaster prevention measure.

Further, both JP-A-59-15097 and JP-A-61-60495 deal with the danger of the entire fueling station such as the occurrence of a fire, for example, when an automobile collides with an individual fueling device. No consideration has been given to the occurrence of dangers specific to such refueling equipment, and the safety of the refueling station has not been sufficiently ensured.

An object of the present invention is to solve the above-mentioned disadvantages of the conventional example, and to deal with fires, earthquakes and other general disasters at a fueling station, as well as disasters specific to a fueling apparatus such as a collision of a car with a fueling apparatus. In addition to avoiding the occurrence of disasters, such as shutting off the power to the refueling equipment, this can be dealt with by leaving it inside or outside the refueling station. It is an object of the present invention to provide a fueling station that can return to the present condition and that can secure sufficient safety especially when it is installed on the ground floor of a building.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a control system in which a plurality of refueling devices are provided on a ground floor of a building surrounded on three or two sides by walls and installed on an island, and the refueling devices are controlled. In a gas station where the devices are installed in the office, the control device shuts off the power of all of the plurality of fuel devices by an output from a fire sensor provided at a key point on the ceiling of the building, and the controller installed in the office. The output from the sensor shuts off the power supply of all the plurality of lubrication units, the output from the vapor sensor provided on the island shuts off the power supply of all the plurality of lubrication units, and the collision sensor provided for each individual lubrication unit A power supply shutoff means for shutting off the power of the corresponding refueling device according to the output from the power supply, and for starting the energization of the refueling device by the output from the power supply return switch provided in the office. The distant reporting means is controlled to transmit wirelessly based on the output from the satellite sensor, the notifying means is controlled so as to report the occurrence of an earthquake based on the output from the seismic sensor, and the notification is made to report the occurrence of a collision based on the output from the collision sensor. The gist of the invention is to provide a control means for controlling the means, and a control means for controlling the notification means to stop the notification by an output signal from a stop switch.
