With the rapid development of economic level and science and technology, industrial enterprises, as the main body of social and economic operation, have higher and higher requirements for safety prevention, and the monitoring system plays an increasingly important role. The factory has a large scale, complex production and management departments, and high safety requirements. The combination of field monitoring and production command and dispatch in numerous production workshops, special outdoor places and functional departments will greatly improve the level of intelligent management of factories. If any mishap occurs, it will bring great pressure to the society and employees, and even serious consequences.
2. Project Overview
2.1 Project Introduction
A new energy power system company, as a benchmark enterprise of new energy vehicles in China, provides battery systems for the global new energy vehicle market. Due to the need of business expansion, there is a temporary workshop with an area close to 9000 square meters for the storage of new energy batteries. Due to the storage of electric energy in the battery, a long time of concentrated stacking may cause battery heating, fire and other conditions. An effective on-site monitoring solution is now needed to ensure the personal and property safety of the storage space and the factory.
2.2 Project environment
In the workshop, the batteries are stored by means of shelves. Each shelf is 6.5m high, and each shelf is divided into 7 layers for goods storage, with an interval of 3.5m. The top view of the factory after the goods are stored is shown in the following figure:

3. Program overview
3.1. Scheme ideas
Both the abnormal heating of the battery in the factory and the potential fire risk are accompanied by the temperature change of the goods. Compared with the traditional manual inspection scheme, the monitoring scheme of the infrared thermal camera can effectively monitor the temperature change of the goods, and can also liberate people. Therefore, this scheme adopts the infrared thermal camera to monitor the temperature of the workshop to ensure the safety of the workshop and the goods. The most prominent feature of this scheme is all digitization. The front end USES infrared thermal camera to store video images and display them in real time through a display.
3.2. Scheme considerations
In view of the different ways of stacking cargo space in the workshop, generally speaking, we have two ways of installation, namely fixed installation and mobile rail installation.
Considering the actual situation of the project, we should also take the following considerations into account:
Reliability: The reliability of scheme design is the root of the feasibility of scheme.
Economy: The economic solution is consistent with the solution pursued by customers;
Fixed installation method can meet the demand of the reliability of project design, the shelf is too high, but because of the plant by monitoring the lens choice of the type and quantity can really solve the factory monitoring comprehensive, do no dead Angle of stacking battery monitoring will be numerous monitoring camera that will inevitably lead to significantly enhance the cost of the project. For the sake of economical completion of the project, no fixed installation method is adopted.
3.3 Project plan
Based on the consideration of various factors and the combination of the current emerging technologies, the construction of this project is finally completed by means of wireless private network transmission with infrared thermal camera as the core and patrol inspection robot as the carrier.
Actual application scenario diagram
Due to the large size of the battery and its placement on the shelf in a layered manner, in order for the robot to efficiently complete the inspection of the workshop, 7 thermal camera lenses will be attached to the inspection robot for the inspection of the shelf according to the height of the shelf.
4. Detailed design of project scheme
This monitoring system is mainly responsible for all-weather monitoring of the batteries stored in the workshop. When the temperature exceeds the set value, it will send an alarm to ensure safety.
4.1 Product selection
Each shelf is 6.5 meters high and 3.5 meters apart. There are 7 layers of batteries stacked on each shelf. It is required to comprehensively monitor the stored batteries.
