Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging facilities technology, and in particular to a dot matrix parking lot fire protection system. Background Technology

[0002] With the rapid popularization of electric vehicles, the number of charging stations in parking lots has increased dramatically. Currently, parking lots generally have the following safety hazards: traditional smoke detectors are usually installed on the roof of the parking lot, but due to factors such as open space and air flow, they cannot detect early fires at individual charging stations in a timely and accurate manner; there is a lack of linkage and early warning mechanisms between various charging stations, making it impossible to achieve precise regional prevention and control; existing fire protection systems for charging stations only focus on their own protection and cannot provide comprehensive safety protection for the entire parking lot.

[0003] As shown in the existing patent document CN217598382U, it discloses an AC charging pile with smoke sensing safety protection, but it is limited to the protection of a single charging pile and cannot achieve regional collaborative early warning. Therefore, there is an urgent need for a charging pile fire prevention system that can achieve distributed sensing, regional linkage, and rapid response. Utility Model Content

The charging pile units 100 are connected via a network to form a distributed detection array; The regional control center 200 processes data uploaded by each charging pile unit 100 in real time to achieve regional fire identification and location.

[0023] Preferably, the smoke sensing module 3 is installed in a three-dimensional manner. The smoke sensing module 3 includes at least a first smoke sensor 31 installed on the top of the charging pile body 1 and a second smoke sensor 32 installed on the bottom of the charging pile body 1, thereby forming a dual detection method from top to bottom.

[0024] Preferably, each charging pile unit 100 further includes a power cable 8 and a charging gun 9 installed on the charging pile body 1 and electrically connected to the main controller 2. The power cable 8 is used for power input, and the charging gun 9 is used for power output.

The second smoke sensor 32 is an ionization smoke sensor located above the power cable 8 and is used to detect early smoke generated by cable overheating. Thus, the first smoke sensor 31 at the top and the second smoke sensor 32 at the bottom are of different types, respectively detecting smoke particles of different size ranges and at different locations.

When multiple charging pile units 100 in a certain area alarm simultaneously, the system automatically calculates the location of the fire source center, activates the corresponding fire extinguishing devices, and guides personnel to evacuate through an audio-visual system.

[0031] Through actual testing, this system was deployed with 36 charging pile units in a 2000-square-meter parking lot. It was able to detect and accurately locate the fire within 3 seconds, with a false alarm rate of less than 0.1%.

[0032] The regional control center 200 of this utility model, in conjunction with each charging pile unit 100, can realize a hierarchical early warning mechanism, wherein: Level 1 warning: An anomaly is detected in a single charging station, triggering a local alarm; Level 2 warning: When three or more adjacent charging piles detect anomalies simultaneously, regional linkage is activated; Level 3 warning: Fire confirmed, activate the entire site's emergency system.
