In the technology-driven changes in the security industry, security inspection robots have jumped up as a key force for security. They tirelessly shuttle in factory parks, large warehouses, commercial complexes and residential neighborhoods and other corners, undertake the patrol, monitoring and other core tasks. The robot battery, as the security patrol robot“energy heart”, its performance is directly related to the robot can be stable and efficient to achieve all-weather operation, which in turn affects the reliability and integrity of the entire security system.
1. Security patrol robot special needs for batteries
1.1 High endurance
The characteristics of the security inspection work determines the robot needs to be a long time, uninterrupted continuous operation, covering a wide area. A medium-sized industrial park covering an area of 50,000 square meters, for example, security inspection robots to carry out comprehensive and detailed inspection of the park, its range usually needs to reach more than 30 kilometers. This means that the robot needs to be in a charge, can run continuously for several hours, to complete the park road, plant perimeter, warehouse area, such as a full range of inspections. In the commercial complex scene, each 10,000 square meters of area, all kinds of stores, passages, public space, the robot hourly patrol coverage is relatively limited. To realize 24-hour uninterrupted patrol, the battery life requirements are almost harsh. According to industry research data shows that more than 70% of the security inspection scene, the robot needs to work continuously for more than 8 hours, which fully highlights the importance of high endurance battery to protect the security inspection work coherence and efficiency.
1.2 Fast charging characteristics
In security patrol work, emergency situations occur from time to time. When unexpected security incidents at night, the security inspection robot urgently needs to replenish the power in a short period of time, and quickly go to the scene. At this time, the battery with fast charging characteristics is particularly critical. Ideally, the battery should be able to half an hour, from a low level of power to meet the degree of hours of work. For example, in a city’s smart security pilot project, the security patrol robot, with only 20% of its battery remaining, was charged to 60% in just 30 minutes with the help of fast-charging technology, allowing it to respond quickly to urgent tasks and effectively improve the efficiency of incident handling. Industry research shows that in more than 60% of security emergencies, if the robot can be recharged within one hour and put to work, the efficiency of the incident can be increased by 30% -50%, which further confirms the importance of fast charging characteristics to ensure the continuity of security inspection work.
1.3 Stability and Reliability
Security inspection work shoulders the important task of guarding the safety of life and property, and can not have the slightest error. As the power source of the robot, the battery must work stably and reliably in a variety of complex environments. In the hot summer, the outdoor temperature in some areas may soar to more than 40 degrees Celsius, while in the cold winter, the temperature in some northern regions will drop to minus ten degrees Celsius. Under such extreme temperature conditions, the performance of ordinary batteries will be seriously affected. According to the test data of professional organizations, in a high temperature environment of 40 ℃, the output voltage of ordinary batteries may drop 10% – 15%, current stability will also be interfered with, resulting in slower robot running speed, reduced precision; and in the -10 ℃ low-temperature environment, the battery capacity may be attenuated by 30% – 40%, and even can not be normal power supply situation. In addition, in a humid environment, the battery also faces the risk of short circuit. Therefore, the battery of the security patrol robot must have a strong ability to adapt to the environment, and always maintain a stable output voltage and current, to ensure the normal operation of the robot’s functions, to build a solid foundation for security work.
2 Problems faced by existing security patrol robot batteries
2.1 Limited range
Traditional lead-acid batteries and some early robot lithium battery, due to low energy density, have become the bottleneck of the security inspection robot range improvement. The use of lead-acid batteries for security inspection robots, the average range is only 10 – 15 kilometers, which means that in large areas of inspection tasks, the robot may need to return to recharge every hour, seriously affecting work efficiency. Earlier lipo robot battery have improved, but most of the range is only 20 – 30 kilometers. A large warehousing and logistics center, for example, the center covers an area of 80,000 square meters, if the use of early lithium battery robotics security inspection robot patrol, at least 4 – 5 times a day need to be charged, which not only increases labor costs, frequent interruptions of the patrol may also lead to security monitoring blank time, laying the groundwork for security risks.
2.2 Long charging time
The charging speed of some common batteries is slow, and a complete charging may take 4-6 hours, some even up to 8 hours. In today’s world of growing security needs, such long charging wait times greatly limit the robot’s work frequency and coverage. For example, in a commercial plaza equipped with 10 security inspection robots, each robot loses an average of 3 – 4 hours of work time per day due to charging, reducing overall work efficiency by about 25% – 30%. Long waiting time for charging, so that the robot can not give full play to its due role, it is difficult to meet the needs of high-intensity security patrol.
2.3 Poor environmental adaptability
The performance of ordinary batteries decreases dramatically in extreme temperature environments. At high temperatures, the internal chemical reaction of the battery is intensified, which is prone to overheating and even the risk of explosion. According to statistics, in a high-temperature environment, the probability of failure caused by overheating of the battery is 20% – 30% higher than that of a normal temperature environment. At low temperatures, the activity of the electrolyte inside the battery decreases, and the capacity of the battery decreases dramatically, so it cannot provide enough power for the robot. For example, during outdoor security patrols in the northern winter, a robot with a normal battery may only be able to operate for half the normal time or even less. In the low temperature – 10 ℃ environment, the battery capacity decline of up to 50% – 60%, which makes the robot in the cold season inspection work is facing a huge challenge, seriously affecting the effective implementation of security inspection work.
3.Innovative Battery Solutions
3.1 High energy density lithium battery
The use of new materials and manufacturing process of high energy density lithium batteries for security inspection robot range improvement has brought the dawn. Lithium iron phosphate batteries, for example, has a high energy density, compared with traditional lead-acid batteries, in the same volume and weight, energy storage can be increased 1 – 2 times. In practice, equipped with lithium iron phosphate battery security inspection robot, range can be increased by more than 50% on the basis of the original. The original range of 20 kilometers of the robot, replacement of lithium iron phosphate battery, the range can easily reach 30 – 40 kilometers, the number of times a day from 3 – 4 times to 1 – 2 times. This not only effectively reduces the number of charging times, but also significantly extends the patrol time of the robot, providing a more reliable guarantee for security patrol work.
3.2 Fast charging technology
At present, advanced fast charging technology has been gradually applied to the field of security inspection robot batteries. Through the use of high-power charging modules and special battery management systems, rapid battery charging can be realized. Under the premise of ensuring battery safety, the optimized charging algorithm can significantly reduce the charging time to 1 – 2 hours. For example, a security inspection robot equipped with fast charging technology only takes about 1.5 hours to charge up to 80% of its capacity from the exhaustion of its power, which is 60% – 70% shorter than the traditional charging method. The application of this technology greatly improves the use of robot efficiency, so that it can respond to security tasks in a more timely manner, effectively enhancing the timeliness and effectiveness of security inspection work.
3.3 Intelligent Battery Management System
Intelligent battery management system is like an intelligent housekeeper, which can monitor the battery’s power, temperature, voltage and other parameters in real time, and intelligently adjust them according to the robot’s working status and environmental conditions. When the temperature of the battery is too high, the system automatically starts the cooling device to ensure that the battery works at a suitable temperature and prolongs the life of the battery. When the power is low, the system will reasonably adjust the robot’s working mode to reduce energy consumption and prioritize the execution of key security tasks. At the same time, through the in-depth analysis of battery data, the system is able to predict battery life and potential failures in advance, facilitating timely maintenance and replacement, ensuring that the battery always maintains stable and reliable operation in complex environments. According to relevant industry statistics, the application of intelligent battery management system, the battery life can be extended by an average of 20% – 30%, the failure rate is reduced by 30% – 40%, for the stable operation of the security inspection robot provides a strong support.
As the security industry’s demand for intelligent and efficient continues to rise, the optimization of battery solutions for security inspection robots has become a top priority. Through the use of high energy density lithium batteries, fast charging technology and intelligent battery management system and other innovative solutions, can accurately crack the existing battery faced with short range, slow charging, poor environmental adaptability and other problems, to effectively protect the security inspection robot all-weather stable operation. These innovative solutions not only for the construction of a safer, more reliable security environment provides a strong support, but also will promote the security inspection robot industry towards a new stage of development, laying a solid foundation for the future of the security field of intelligent upgrading.
