Advertising is a form of information service. The emergence of wireless car LED screens provides the possibility to deepen the advertising market and fully display the corporate elements. It has convenient placement (free movement), investment province (zero wiring project investment), large information capacity (the same carrier for multiple advertisements), efficient and fast (regardless of the vehicle media, no matter how many, several seconds of information can be sent. ), the carrier utilization rate is high (manpower and material cost of advertising change is almost zero), and the advantage of good night vision is unmatched by traditional wired screens.
The wireless LED information screen, with its advantages of wireless receiving, storing and displaying information, can only be set up in a fixed location and can not be widely used in the region. The single information service mode of the media is expanded into a comprehensive information service mode to make comprehensive information The direction of service development. The GPRS information screen uses the reliable GPRS/CDMA network and the perfect large-capacity data transmission platform to show the advantages that the traditional wired screen can't match. It can not only transmit text information, dynamic patterns, image information, but also realize remote full-function remote control, eliminating the huge engineering cost of breaking the trench. The application prospects are self-evident.
The taxi GPRS/CDMA wireless LED advertising system launched by Zhongshan Technology is specially designed from system software to terminal hardware equipment. It has advanced technology, more reliable performance, convenient installation and use.
Terminal product features
★ The information of the terminal screen is transmitted and received based on the GPRS/CDMA data mode. The use of the terminal media is not restricted by the region, and it is a mobile advertising carrier with excellent mobility.
★ Professional GPRS/CDMA communication protocol, long-term work is stable and reliable, and can display the display contents of tens of thousands of terminal screens within a few seconds.
★ The terminal can store the content of the advertisement information, and can be displayed for a long time with one update, without having to download from the center repeatedly.
★ The built-in font of the terminal does not require the dot matrix information of the central downlink font. The GPRS/CDMA communication traffic is extremely low, which is very suitable for wireless control.
★ Diversified carrier information. The memory can hold up to 10,000 lines of ad text.
★ The text display mode has a variety of effects such as left shift, down shift, scroll unfolding, etc. The speed is adjustable at 30 levels and the pause time is adjustable at 50 levels.
★ High contrast, it can be clearly displayed under direct sunlight, and it is fully adapted to outdoor light brightness.
★ Reserved interface: It can expand GPS positioning and vehicle alarm function, making full use of original equipment resources.
Management Center Software Features
Designed for GPRS/CDMA LED advertising, it supports tens of thousands of terminals online, and the advertising content is updated synchronously.
Support ADSL+ dynamic domain name to build a management platform, without renting fixed IP address lines, saving central investment.
It has the group management function of the car, which is convenient for the targeted release of advertisers.
Support single screen and group publishing, you can view the working status of each LED screen and the latest release content in real time.
Provide advertising plan management, you can create and manage multiple advertising plans.
Multiple sets of ad text content and text display effects can be set independently in each ad plan.
Reserved interface: an expandable electronic map showing the location of the vehicle and a central display of vehicle alarm information.
It can expand interfaces such as weather information and traffic condition information.
system structure
The entire taxi wireless LED advertising system consists of two parts: the car wireless LED display and the management center system.
2.1 Car LED display
The car LED display is placed in the rear window of the taxi (see Figure 1). It can display two rows of 12 words, or 192 dots x 32 dots, depending on the space. It can be displayed in monochrome, two-color or color. The display can store multiple texts or pictures, and store a program list, which can set the display time and entry effect for each screen advertisement, or continuously play the multi-screen picture to form an animation. In order to clearly see the display content during the daytime sunlight, the LED display must use high-brightness LEDs. The display power supply is provided by the car battery.
2.2 Management Center System
The management center system is mainly composed of advertising management software and network equipment, which is used to manage the customer's advertising content and broadcast plan, and realize the manual or automatic advertisement to the vehicle display screen. Due to the large number of advertisers, each customer's advertising is delivered. Both quantity and delivery area have requirements, so the software must be able to manage the vehicles in groups and deliver advertisements to individual vehicles or multiple vehicles according to customer requirements.
The overall structure of the system is shown below:
Comparative advantage of GPRS/CDMA wireless LED electronic screen
As a new kind of information media, wireless electronic display has attracted the attention of a wide range of social groups. Different from the traditional wired LED display, it can receive, store and display a large amount of text information wirelessly over long distances, and control the display mode of text and fonts and the timing display function through the built-in microprocessor. It completely got rid of the shackles of the traditional electronic screen "wired connection", making its application more market-oriented and wide-area. Its "flowing" display features are more admired by the advertising industry and are a brand new medium.
Traditional LED electronic screens obtain information by wire. The wired method (distance limited to 200 meters) shackles the wide range of applications of the screen, even if it is connected with a dedicated network, the huge engineering overhead is unbearable for investors. If screens are set up in multiple locations and multiple locations along highways, plazas, buildings, traffic intersections, dynamic carriers, etc., and simultaneous information is required, the use of wired screens is not economically feasible. As a wide-ranging application of electronic screens for information display terminals, the application of wireless technology is the only way out in terms of economy, effectiveness and convenience.
Compared with the previous GSM short message transmission advertising information, the transmission technology of GPRS/CDMA wireless LED screen has the advantages of strong real-time data, high reliability, large information capacity, strong function expansion, low transaction cost, etc., GPRS/CDMA data communication. The method has replaced the short message communication method and has become the preferred solution in the wireless remote transmission system of various industries.
The Copper cable Terminals are suitable for the connection of copper conductors (section 1.5mm2 - 1000mm2) in power cable with electronic equiment they are made of with higher 99.9 percent pure copper tube T2 and coated with tin. Working temperature:-55℃ - 150℃ .The Copper Cable Terminal Lug is a connecting terminal for electric power transmission and connection, which comprises an aluminum terminal body, one end of the terminal body is in the shape of a circular tube and the other end is a flat plate, on one surface of the flat body part of the terminal body is provided with a copper plate Layer, the copper layer and the corresponding plate portion is in close contact with the fusible connection into an integrated non-fiber structure. The terminal of the utility model is integrally welded and connected with the copper sheet layer on the integral aluminum terminal body, the connection is reliable and does not fall off, the integral strength of the terminal body is high and does not collide and break; the non- Low current loss, improve transmission efficiency and voltage transformers pressure, and the production of only a small amount of copper, drastically reducing the copper consumption and reduce costs
