Gas station security project market will reach several billion yuan
At present, gas stations generally need to set up 4-5 cameras in the station, and a few gas stations can be added to 8 cameras. The camera in the shelter area in the monitoring station needs to use a zoom lens, with the pan-tilt head for comprehensive inspection and monitoring. The fixed-focus lens is adopted in the business hall, the financial room and the warehouse area, and the entire scene is monitored under the jurisdiction of the jurisdiction. For aesthetic considerations, an integrated dome camera can be installed indoors. An embedded hard disk recorder is set up in the monitoring room, and the monitoring range of the remote camera is controlled by the button on the display layer. At the same time, an emergency button and an acousto-optic integrated alarm were designed in the monitoring room. In case of emergency, the emergency sound and light integrated alarm can be pressed to issue an alarm, and the alarm signal can be transmitted through the network to the sub-control center or the 110 alarm center (in the case of networking). Therefore, the composition of the gas station video surveillance system includes: network video server; central monitoring computer; central monitoring software; camera; PTZ (optional); PTZ decoder (optional) emergency button and sound and light alarm.
The monitoring point consists of high-definition cameras, PTZ (optional), and PTZ decoder (optional). The monitoring center is composed of high-performance PC and central monitoring software. It can realize the selection, switching of multi-channel video, real-time display of multi-channel video, PTZ control, alarm display, alarm linkage, and multi-channel video real-time storage and playback. Features.
At present, the remote centralized monitoring system of gas stations consists of two parts, each fueling front-end monitoring equipment and a remote monitoring center. Among them, each gas station connects each camera's image to a local recording device (ie, an embedded hard disk recorder), digitally compresses the analog image through an embedded hard disk recorder, and uploads it to a remote monitoring center via a dedicated line or ADSL network; a remote monitoring center. Equipped with a certain number of monitoring and management computers, perform monitoring, video, management and other functions.
The above-mentioned monitoring system adopts two-level management methods, namely, gas station monitoring host and remote central monitoring host. They adopt advanced digital compression monitoring system (computer monitoring) monitoring method, and the digital computer automatic monitoring program implements the target range in real time. Monitoring, recording and reproduction, the captured objects are saved on the system hard disk in the form of files, which can easily reproduce the monitored contents at any time.
For a single gas station, according to the actual conditions of the site and the needs of gas stations, a color intelligent low speed dome camera and several high-resolution color cameras are installed at important positions such as vehicle import and export, charge halls, and refueling areas at each gas station. Camera; Color smart low speed dome camera mainly monitors the entire gas station periphery, and high definition cameras can perform fixed-point high-definition video surveillance on key parts.
The overall system design can be divided into the following components: front-end camera system; video transmission system and wiring; video control system; video display and recording system;
In the monitoring center, real-time video monitoring and recording are performed on each front-end monitoring point, which not only realizes the recording of video signals, but also realizes video viewing and video storage. Therefore, the center must be equipped with an embedded hard disk recorder.
From the perspective of transmission equipment and lines, choosing which medium and equipment to transmit images and other control signals will directly affect the quality and reliability of the monitoring system. At present, the media used to transmit image signals in gas station monitoring systems mainly include coaxial cables, twisted pairs and optical fibers. The corresponding transmission devices are coaxial video amplifiers, twisted pair video transmission devices and optical transceivers, respectively. For gas station security project construction, to establish a high-quality monitoring network, we must find out the characteristics of these three major transmission methods and the use of the environment in order to take the appropriate transmission medium and equipment for the actual project needs:
Because of the limited transmission distance of the gas station, the coaxial cable has the advantages of cheaper price and convenient installation. The transmission of video signals generally uses coaxial cable transmission. The optical fiber transmission method is mainly used for networking between various gas stations and provincial monitoring centers.
In general, the gas station has 5-8 cameras, and its video signal is directly connected to the local embedded hard disk recorder to store it. In addition, the power supply system consists of two parts: the power supply of the equipment room: all the equipment in the equipment room is powered by 220V AC power, which is generally required by the UPS power supply; the camera is supplied by a 12V power supply, and the low speed ball is powered by an AC24V power supply.
From the above, we can see that the factors affecting the safety construction cost of a gas station include: number of cameras and their type selection (5-8 units); embedded hard disk recorders and their types (1); multiple input or single-channel video servers And its selection (5-8 units); transmission line selection (special network or shared network) and wiring; power system (1 set);
It is worth noting that, as the non-refueling business of the gas station gradually unfolds, the monitoring point may expand to the shopping mall of the gas station, which includes at least 2 firearms and at least 1 ball machine.
For a region--provincial-gas station network security monitoring system construction, the cost of building a provincial monitoring and management center must also be taken into account. The main factors affecting the cost include: monitoring and management center host, large screen, supporting software systems and interface design with other systems.
According to the latest data released by the two giants of China National Petroleum and China Petrochemical, the total number of gas stations owned by the two companies (including self-operated and franchised operations) was 17,456 and 29,484 respectively, which accounted for the total number of gas stations in the country. 51%. Based on this analysis, the total number of gas stations in the country is approximately 92,000. Based on the above data analysis, industry experts believe that the monitoring system for a gas station costs about 5,000 yuan. According to our analysis, the cost of the monitoring system for each gas station is estimated to be around 10,000 yuan, based on the calculation of 5-8 cameras per station and the supporting systems. Therefore, the scale of equipment required for construction of gas station security projects nationwide is approximately (10,000 yuan x 92,000 yuan) 1 billion yuan. This does not include the cost of building a private network or a shared service bearer network.
In addition, the construction of the gas station security monitoring system is characterized by multiple points and decentralization, taking into account engineering design, installation, system integration, provincial monitoring and management centers (including the construction of dedicated transmission networks and the construction of large-screen displays), and supporting facilities. With the cost of software and after-sales services, it is estimated that the whole gas station security project will be built—the market scale of the complete industrial chain from front-end to back-end will be more than 2 billion yuan.
Estimated by the total number of current gas stations, the demand for cameras (bolt and dome) for the entire gas station security project is expected to reach more than 450,000 units and 100,000 units respectively; if analog cameras + video servers are used, digital video is required. The demand for servers is expected to reach more than 550,000 units, and the demand for DVRs will be around 100,000 units. According to the requirement of 500 meters of coaxial cable for each gas station, the demand for wiring is more than 46,000 meters. Figure 1 shows the demand for major equipment in the gas station security engineering construction market.
From the cost point of view, the main solution for gas station security monitoring system is analog cameras and video servers to achieve cross-regional network monitoring of gas stations. At present, the large-scale installation of new or replacement IP cameras in gas station security projects is driven by the market. The force is not obvious. Therefore, with the popularization of remote centralized monitoring systems for gas stations, video servers that convert from analog to IP may become one of the fastest growing areas in the gas station security engineering construction market.
However, will IP cameras be used on a large scale in new gas stations? We believe that the key is to look at the non-refueling business of gas stations, such as whether the integration with intelligent transportation systems will generate new monitoring needs. At the same time, we must also look at the process of China's security industry moving from analog to IP.
Finally, it is worth mentioning that according to the data provided by the Ministry of Communications, China will build 50,000-5.5 million km of expressways in 2010, and by 2030 the national highway will reach 85,000 kilometers, that is, in the next 20 years. The number of gas stations required for highways alone will be - Fan, a conservative estimate. The total number of gas stations in China is expected to reach 150,000 to 200,000. The construction of new gas station security projects will be at least 6 billion yuan.
In the construction of gas station security projects, an unavoidable problem is that the integrated integration of the four systems of security monitoring, alarm, fire control, and business management will also have a significant impact on the project cost.

Tell you the truth at the end
Some famous Led sellers announced that they are USA OEM, which is clearly a lie. 90% of led grow lights are made in China, even though you don't want to believe, but it is true. They stock larger amount of led lights from Chinese factory, then sell them online by sticking with their own logo. So don't be fooled by the so-called US OEM.
Truth 2
Some famous led sellers exaggerated the function of Led grow lights. We just want to inform you that if you did not change the traditional growing method, you would not get the high yield. Because the led grow light can not play the full role during the traditional growing method. So communicating with growers who have experienced this then you can try it yourself. Please remember that the growing method is the key point for the high yield.
Truth 3
Do not buy cheap led grow lights any more or some which looks like our lights. The lamp will be put on the market to be designed and tested, and this period is at least six-months or more, what are the details what you won't see. Furthermore, the materials we use are not cheap, such as "Cree" chip and Led Lens. Those two parts can be able to ensure the high output. So do not believe that such $xx.99 can buy led grow lights. It's unbelievable.
