Foreword: Stepping motor technology development in high-speed ball, stepping motor is one of the key components of high-speed ball movement. High-speed ball manufacturers attach great importance to the process of stepping motor drive in the development of high-speed ball, using differential pulse technology to control rotation The angle and speed make the high-speed ball can be accurately positioned and has a good handling feeling. The best indicator of the performance of the stepper motor is the minimum speed control level and the preset point accuracy, as well as the birth history of the stability high-speed ball. It is not long, but it is favored by users because of its compact appearance, flexible control, and intelligence. Many of the dome manufacturers are also increasing their efforts in research and development of high-speed domes. Now, the basic control functions of high-speed domes have been implemented by various manufacturers. Pretty mature. The diversity of functions, networking, and intelligence can be said to be the main trend of current fastball product development.
Introduction to key components
Stepping motor is one of the key components of high-speed ball movement. High-speed ball manufacturers pay great attention to the process of stepping motor drive when developing high-speed ball. Differential pulse technology is used to control the rotation angle and speed so that high-speed ball can be accurately positioned. With a good control feel, the best indicator of the performance of a stepper motor is the lowest speed control level and preset point accuracy, as well as stability.
The third key component of high-speed dome cameras is the brush. It ensures that the integrated smart dome accurately transmits video signals and control signals when continuously rotating 360 degrees horizontally.
The horizontal and vertical motions of the high-speed ball are respectively performed by two stepping motors. Various motion commands issued to the high-speed ball are all achieved through a microprocessor-driven motor. The quality of the motor determines the speed of the high-speed ball. The parameters of the motion, such as high-speed scanning of preset points, low-speed capture of large magnification, cruise queues, pattern scanning, automatic tracking, and the accuracy of click-magnification, are all dependent on the processing and precise control of the motor. The degree of image jitter at the minimum speed control can reflect the performance of the high-speed ball; the precision of the preset point also depends on the precision of the mechanical structure and the performance and control level of the stepper motor. It can be said that the motor control level can be It truly reflects the level of high-speed production of the enterprise.
Diversification of functions
The functional diversity of high-speed dome cameras means that the product features will be more powerful, suitable for different environments, and have better compatibility. Click to enlarge and automatic tracking function are the two major technological breakthroughs of the recent high-speed ball. Click to enlarge means that in the monitoring process, when the monitoring target is found, the object is clicked with the mouse, and the high speed ball transfers the image to the center of the screen and intelligently enlarges according to the size of the clicked object. The automatic tracking function is based on the image processing technology to extract the motion vector in the image, and the high-speed ball moves according to the moving direction of the moving object in the image. This is also called an intelligent high-speed ball.
Lightning protection technology has always been the subject of high-speed ball research. In the past, lightning protection for control signals has only been adopted. In recent years, high-speed cameras have also made major breakthroughs in video lightning protection.
The emergence of network high-speed ball is the inevitable outcome of monitoring digital development. The use of now convenient and fast network technology to transmit video and control signals will greatly expand the application of high-speed ball in the monitoring industry, especially the highway and power industry.
Intelligentization is mainly reflected in the intelligent identification (Face Recognition Alarm, Abnormal Recognition Alarm, License Plate Recognition, etc.) that is composed of Speed ​​Dome and other devices, automatic tracking (moving object tracking), alarm linkage, and automatic alarm recording. The application is more familiar, smarter and humane.
In addition to intelligence and networking, the next-generation high-speed ball should also have better performance than ordinary high-speed ball in the following aspects.
1. Better concealment. That is, the concealment of the whole machine or the concealment of the direction of rotation of the lens is better. How to miniaturize the whole machine and how to embed it into the application environment effectively and harmoniously will be the focus of designers.
2, a simpler and more flexible installation. At present, the installation of high-speed balls by some manufacturers is complex, time-consuming and laborious, which greatly affects the market promotion of products.
3, easy to operate. The use of visual menu design makes the operation easier. The humanization and general design of operations will be an increasingly important factor influencing product marketing.
4, stable quality, reliable performance. This is the most fundamental and most important indicator of high-speed ball. Power stability, lightning protection and anti-surge capability, motor quality, main processing chip performance, slip ring quality, and all-in-one performance are all key factors that determine the stability and reliability of high-speed ball, and should be the focus of designers in the design process. problem.
5, effectively reduce the cost of the whole machine. The lower cost is an important factor that prompts the rapid expansion of demand in the high-speed ball market.
6, modular design. The various functional parts of the high-speed ball are designed in a modular manner so that they can be matched with each other, which improves the flexibility of sales and better meets the needs of users. Of course, the specific implementation of this work is not difficult, and it requires a thorough and careful consideration at the beginning of product planning.
7, the compatibility of a variety of protocols and automatic recognition of the movement and control protocol. At present, high-speed domes generally adopt the method of selecting protocols through dialing switches or menus. Automatic identification of movements and control protocols will bring more practical significance to product users or project installers or even manufacturers themselves.
With the increasing number and complexity of emergencies in social security, people's protection requirements for public safety are getting higher and higher. The integrated high-speed smart ball has gained popularity among consumers because of its own advantages, especially with the monitoring of urban security. The development of high-speed ball has received unprecedented attention. Since 2006, high-speed ball has made remarkable achievements in urban public roads, public security, public communities, large-scale public buildings of sea, air and seaports. With the development of economy, the speed of urban construction has been accelerating, the urban population has become more and more dense, and the population mobility has increased. This has led to problems in urban public security such as traffic, social security, and increased difficulty in prevention in key areas. High-speed ball has a wide range of monitoring. Easy to install and operate, it has become one of the fast-growing products in the security market in recent years, so it can be said that the construction of a safe city has promoted the rapid growth of high-speed ball speed.
In short, the technological development of the high-speed ball and the market need is a process of mutual influence and mutual promotion. On the one hand, there is a market need to promote the further development of technology and better application to the product; on the other hand, the development of technology will inspire more market demand. Digitalization is an important feature of the contemporary electronics industry. Relying on the networking and intelligent products of digital technology has become a basic direction for the development of many electronic products. The development of high-speed ball technology will also integrate three basic features of digitalization, networking, and intelligence. It will continue to appear more suitable and effective functions to meet market needs, and guide and stimulate more market demands, and finally build a good one. Social public security system.
