Presentation of Performance ofcell phone jammer
By the computer system hardware, cell phone module, power adapter and serial port lines. In order to improve the system's versatility as well as to take account of concurrent users to send text messages and unexpected, the software part of the front desk by the back-end database and application components. In order to facilitate the management of messages, using the back-end database to store the user's outgoing text messages and received messages, the messages can be complicated when large buffer, but also store cell phone numbers and other contact information. The performance of cell phone jammer will be presented in the video.
Also facilitates with other enterprise information system integration, and other systems simply operate on the database can be completed to send and receive SMS functionality. Foreground program first complete system initialization, set the serial communication baud rate, and short message service center number. Outgoing messages from the database to read through the code (using PDU mode, all use UCS2 encoding, up to 70 half-angle / full-width characters) along with the AT commands sent through the serial port to the GSM MODEM, and to detect sent successfully or not, the timeout retransmission ; read from the SIM card inserted into the incoming SMS database, and remove it from the SIM card. While the foreground program also provides: SMS group sending, support groups defined using this system to send text messages, you can choose to send objects into several groups. The manager will perform the presentation of performance of cellualr phone jammer in the form of the video.
Can also be a few people, but also issued a notice for corporate internal and external advertising; No. segment mass; regularly sent; cell phone book management, users can maintain contact from the contacts; common message management, users can maintain some common short message, to add, delete, modify, etc, these messages can be sent directly to select the send and other functions. Workflow system shown in Figure 1. As the strong real-time messaging, the program opened a separate thread using the timer cycle control messaging, the main thread to complete the database interface and other related support functions. Patients are sent to the cell phone number 13712345678 reads "Hello, Hello!" SMS, SMS center number is 13800551500. The customer wanna the copy of the presentation ofcell phone jammer.
Which 1683108501505F0 is encoded message center number, 11 - header bytes, 00 - the type of information, 0D-called number length, 91 - called number type, 683117325476F8 for the called number, 4F60597DFF0C00480065006C006C006F0021 is encoded after the actual content of as: "Hello, Hello!" information content. Note that the low front, high in the post, "F" to fill the whole. Control serial port are generally three kinds, MSCOMM, API, third-party class, in this way using the API system, the following code demonstrates the open serial port, send text messages, close the serial port of the whole process. In a real system, as long as the appropriate control to the serial port to accept AT commands can be achieved SMS, delete messages and other related functions, while the above code needs to be packaged for multiple functions, in order to improve code reusability and maintainability. SMS-based mobile platform using VC module implemented using a database interface, the great news of the cache, in the face of the impact of large flow of work and still get smooth, stable running platform, use in good condition. The intelligent mobile phone jammer system needs the further enhancement.
Performance in the 19200B / S communication rate, the average message transmission up to 800 / h or more (the number is correct, a good signal), the module can use multiple cell phones or GSM MODEM pool to enhance the system capacity. When using multiple GSM MODEM, when a MODEM for each open a separate thread, each thread in parallel send and receive text messages without disturbing each other, the majority of computers currently only two COM interfaces, so if you need to greatly enhance the system capacity can be considered Usb interface 4/6/8 way using GSM modem pool, doubling the data transmission efficiency. The intelligentcell phone jammersystem is well welcomed in the market.
