Fig. 1 is a block diagram of a real-time fire monitoring system of a charging pile according to an embodiment of the present application, as shown in fig. 1: the real-time fire monitoring system of the charging pile of the embodiment may include:
a first obtaining module 110, configured to obtain, when the charging pile is in a working state, a current temperature of the charging pile and a vehicle battery temperature, where the vehicle battery temperature is obtained through a pre-established communication link;
in this application, fill electric pile between operating condition, fill electric pile's BMS (BATTERY MANAGEMENT SYSTEM ) and the BMS of vehicle and carry out handshake communication, after the message is received and sent, fill electric pile and begin work, then fill electric pile and last output current and charge the BATTERY among the new energy vehicle. In this process, the BMS of charging stake can gather and charge stake temperature, and the BMS in the vehicle can gather the temperature of vehicle battery.
The monitoring system in this application inserts the BMS who fills electric pile, directly acquires the battery temperature who fills electric pile. The monitoring system is further provided with a near field communication network covering the charging station, when the vehicle enters the charging station, the vehicle automatically accesses the near field communication network, and the battery temperature in the BMS is sent to the monitoring function system through the near field communication network. In addition, the vehicle can be connected with the vehicle through the mobile network, when the vehicle charges through the charging pile, the vehicle is positioned to enter the changed area, and the vehicle is connected with the monitoring system in a request mode. The above connection mode can be implemented in a pre-agreed manner.

In case that the temperature of the charging pile or the battery of the vehicle is too high, there is a possibility that there is a fire risk. At this time, video monitoring needs to be performed on the charging post and the charging cable (since the vehicle camera is called in the present application, there may be a case where the charging post has only one charging vehicle, and thus the self image cannot be captured, and thus the vehicle itself is not captured). At this time, the monitoring system transmits the request information to all vehicles establishing the connection, and the monitoring system sets a near field communication network or performs positioning through a mobile network. Thus, a request can be made for all vehicles of the charging station. The method comprises the steps of acquiring camera invoking permission of a target vehicle in a charging station, wherein the target vehicle refers to a vehicle with an external video shooting capability.
Specifically, transmitting the request information to the target vehicle includes:

After obtaining the use permission information from the target vehicle, the vehicle machine can obtain the environment image acquired by the external camera according to the shooting mode of the instruction by sending the instruction. Because not all environmental images can contain the charging piles in the working state, further screening is also needed, and the following steps are specifically performed:
in an embodiment of the present application, acquiring a target environment image acquired by an external camera from the target vehicle includes:
acquiring environment image data acquired from all target vehicles, wherein the environment image data comprises an environment image and a camera physical MAC for acquiring the environment image;

In this embodiment, the vehicle machine responds to the instruction sent by the monitoring system, firstly, collects a frame of image and returns the image to the monitoring system, the monitoring function system identifies the image based on the existing digital identification model, and if the image includes the number of the charging pile being charged, the corresponding camera can directly collect the image of the charging pile. Therefore, a corresponding camera is found based on the corresponding physical MAC, and then the environmental image collected by the camera is continuously requested, wherein the request frequency is 0.5s-1.5s, namely, one environmental image is collected every 0.5s-1.5 s. Thereby obtaining a target environment image.
And the monitoring module 140 is used for carrying out fire monitoring on the charging pile and the charging cable based on the target environment image.

and carrying out fire monitoring on the charging pile and the charging cable based on the identification result.
In this embodiment, since the number of the target environmental images is large, if the target environmental images are identified one by one, the calculation is very occupied, so in this embodiment, similarity comparison is performed on the outline features of the gray features of any two frames. If the similarity of the contour features of any two frames of gray features is smaller than a preset threshold value, the situation that dynamic changes exist in the two frames of images is indicated, and the dynamic changes caused by smoke and sparks are possibly generated, so that the two frames of images are further identified through an identification model. The above process can improve the monitoring efficiency.

converting the multi-frame environment image into a gray image;
extracting outline features in multi-frame gray level images;
comparing the similarity of the contour features of any two frames of gray features, and identifying the contour features based on a pre-established smoke and spark identification model to obtain an identification result when the similarity of the contour features of any two frames of gray features is smaller than a preset threshold;
and carrying out fire monitoring on the charging pile and the charging cable based on the identification result.
5. The real-time fire monitoring system of a charging pile according to claim 4, wherein the profile features are extracted by a CANNY operator.
6. The real-time fire monitoring system of a charging pile according to claim 4, wherein the similarity comparison of the profile features of any two frames of gray scale features comprises:
and calculating the Hamming distance of the contour features of the gray features of any two frames, and taking the Hamming distance as the similarity of the contour features of the gray features of any two frames.
7. The system for real-time fire monitoring of a charging pile according to claim 4, wherein the process of establishing the smoke and spark recognition model comprises:
acquiring a positive sample image and a negative sample image, wherein the positive sample image comprises smoke or sparks, and the negative sample image does not comprise smoke or sparks;
extracting outline features of the positive sample image and the negative sample image, and labeling the outline features of the positive sample image and the negative sample image to obtain training data;
and training the artificial neural network based on the training data to obtain a smoke and spark recognition model.
8. The real-time fire monitoring system of charging pile according to claim 4, wherein the acquisition time interval between any two frames of gray scale images is between 0.5s and 1.5 s.
9. The real-time fire monitoring system of a charging pile of claim 1, further comprising:
and when the use permission information from the target vehicle is not received, sending alarm information to a target object.
10. The real-time fire monitoring method of the charging pile is characterized by comprising the following steps:
when the charging pile is in a working state, acquiring the current temperature of the charging pile and the temperature of a vehicle battery, wherein the temperature of the vehicle battery is acquired through a pre-established communication link;
when the current temperature of the charging pile or the temperature of the battery of the vehicle is greater than a preset threshold value, sending request information to a target vehicle, wherein the request information is used for requesting the use authority of an external camera of the vehicle, and the target vehicle is connected with the monitoring system when entering a target place where the charging pile is positioned or being charged;
acquiring a charging pile image and a charging cable image acquired from an external camera of the target vehicle when use permission information from the target vehicle is received, wherein the use permission information is generated based on the request information;
and carrying out fire monitoring on the charging pile and the charging cable based on the charging pile image and the charging cable image.
