Specific implementation

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments only are a part of the embodiments of the utility model, not all the embodiments.

[0024] As shown in the accompanying drawings, Figure 1 to the accompanying drawings, Figure 5 As shown in the accompanying drawings,

[0025] An AC charging pile with a temperature monitoring and alarm mechanism includes an AC charging pile 1, a charging gun 2 is fixedly connected to the output end of the outer wall of the AC charging pile 1, a display screen 3 is fixedly installed on the outer wall of the AC charging pile 1, a button 4 is fixedly installed on the outer wall of the AC charging pile 1, a shell 5 is fixedly connected to the top of the AC charging pile 1, a mounting bracket 15 is fixedly installed on the upper surface of the shell 5, a camera 8 and a thermal imaging sensor 13 are fixedly installed on the top of the mounting bracket 15, a battery 20, a main controller 21 and a remote communication module 22 are fixedly installed inside the shell 5, the camera 8, the thermal imaging sensor 13, the main controller 21 and the remote communication module 22 are all electrically connected to the battery 20, and the camera 8, the thermal imaging sensor 13 and the remote communication module 22 are all electrically connected to the main controller 21.

[0026] It is worth mentioning that the camera 8, thermal imaging sensor 13, main controller 21, and remote communication module 22 can adopt conventional products in the existing technology, which have been fully disclosed and therefore will not be repeated in the specification. For example, the main controller 21 can adopt the MSC1211Y5 microprocessor of Texas Instruments [TI Company] of the United States, and the remote communication module 22 can adopt the MC39 I module of Siemens. When the user inserts the mobile phone SIM card into the card slot to provide the GSM network, the MC39 I module can perform remote data transmission.

[0027] In the above technical solution, the camera 8 and the thermal imaging sensor 13 are installed in parallel. When the camera 8 and the thermal imaging sensor 13 are working, the camera 8 separates the brightness information and color information in the real-time collected image and transmits it to the main controller 21. The thermal imaging sensor 13 transmits the collected infrared image to the main controller 21, so that the shooting range of the thermal imaging photo is consistent with that of the conventional photo. The image and the thermal imaging picture are overlapped, and the flame and smoke characteristics of the electric vehicle battery are respectively recognized through the image, and the temperature characteristics are recognized through thermal imaging, thereby improving the accuracy of fire identification and reducing the risks of false alarms and missed alarms.

[0028] When the flame area in the image captured by the camera 8 coincides with the abnormal high temperature area in the thermal image captured by the thermal imaging sensor 13, it is determined to be a fire. The main controller 21 controls the AC charging pile 1 to cut off power, and notifies the backstage staff through the remote communication module 22.

[0029] It is worth mentioning that the temperature monitoring alarm mechanism needs to establish a data set in the main controller 21 and store the data set in the background memory of the main controller 21. The data set contains typical fire pictures and manually marked fire pictures, including electric vehicle fires, lithium battery, lead storage battery, fuel cell and other battery fires, as well as cigarette butts, lighters and candle flames that do not pose a fire risk. Abnormal flames, normal flames and smoke in the pictures are marked by annotation software, and the data set is exported;

[0030] The camera 8 is mainly used as the visual recognition subject. The camera 8 separates the brightness information and color information in the real-time image and transmits it to the main controller 21. Based on the angle between the camera 8 and the electric vehicle parking space, the main controller 21 identifies the electric vehicle area, the chassis battery area, and human body recognition in the image. By analyzing the image and combining the data set, the main controller 21 identifies the smoke, flame and other conditions in the image.

[0031] The thermal imaging sensor 13 transmits the collected infrared image to the main controller 21. The main controller 21 detects the abnormal high temperature area through the image feature algorithm and determines whether the temperature and thermal pattern are consistent with the flame situation, further improving the fire identification accuracy and reducing the risks of false alarms and missed alarms.

An alarm light 9 and a horn 10 are fixedly installed on the top of the AC charging pile 1, and the alarm light 9 and the horn 10 are electrically connected to the main controller 21.

[0033] In the above technical solution, when it is determined that there is a fire, the main controller 21 triggers the speaker 10 to sound an alarm and the alarm light 9 to flash to alert nearby people. At the same time, the main controller 21 controls the AC charging pile 1 to cut off power and notifies the background staff through the remote communication module 22.

[0034] As attached Figure 2 To the attached Figure 7 As shown, an outer protective cover 6 is fixedly installed on the top outer wall of the AC charging pile 1. The outer protective cover 6 is C-shaped, and the top of the outer protective cover 6 is fixedly connected to the outer cover plate 12. The camera 8 is located inside the outer protective cover 6.

A slewing bearing 16 is fixedly installed on the outer wall of the outer shell 5. The gear 19 is engaged with the inner ring of the slewing bearing 16, and the outer wall of the inner ring of the slewing bearing 16 is fixedly connected to the inner protective cover 7. The outer protective cover 6 is C-shaped, and the inner protective cover 7 is located inside the outer protective cover 6. The top of the inner protective cover 7 is fixedly connected to the inner cover plate 11, and the reduction motor 17 is electrically connected to the main controller 21.
