The so-called SMS cat is actually a device used to send and receive text messages. Like the mobile phones we use, it requires the support of a mobile phone card. When you need to send and receive text messages, insert a mobile phone card we usually use into the SMS modem, plug in the power, and connect it to the computer through the data cable (B or serial port, network port). This can be achieved in the computer's application management software. SMS sending and receiving function. Working Principle
The principle of SMS Cat sending and receiving text messages, the rate is the same as that of our usual mobile phones, but because SMS Cat focuses on SMS sending and receiving applications, compared to mobile phones, SMS Cat is faster in sending and receiving SMS messages. , higher reliability, real-time sending and other advantages, it is widely used in current enterprise text messages
Standard SMSCat SMSCat hardware + SMSCat secondary development kit. Standard SMS Modem is an organic combination of SMS Modem hardware and software.
- SMS Mode is a communication gateway device developed by China Mobile
Business Network based on wireless methods for sending and receiving text messages
. This device can easily be used to quickly send and receive mobile text messages through the local wireless network, thereby enabling users (enterprise systems) to dynamically send and receive text messages without accessing the Internet. Standard SMS Cat SMS Cat hardware + SMS Cat secondary development kit. This statement is not accurate. To be precise, SMS Cat hardware is a pure hardware and a non-intelligent device. The device communicates through the serial port of the computer and through instructions Take control. The SMS secondary development kit is designed to allow developers of upper-level languages, or programmers who are not familiar with low-level hardware instructions, to quickly develop applications and integrate the SMS mode into their own systems. interface method. There are many kinds of SMS secondary development interfaces, such as SMS secondary development controls, dynamic link library interfaces, and database interfaces that are encapsulated into middleware or encapsulated into an rr. The SMS module is the main electronic component that realizes the function of sending and receiving SMS. It is an industrial-grade accessory based on wireless technology. It is an embedded wireless communication module that is combined with peripheral circuits and circuit boards and inserted into the mobile operator's mobile phone. The card can establish a wireless connection with the mobile operator's SMS center, and the local computer-controlled application system can realize free sending and receiving of SMS through the connection with the mobile operator.
Development and Application
The commonly used core modules of SMS mode are: Siemens and. Among them, Siemens SMS modem is divided into two types: mobile phone version and industrial module version. The mobile phone board is mainly 3. Siemens industrial SMS modems are mainly divided into two types: original and original. There are mainly .3 types. The SMS modem is connected to the computer through the serial port R3, and can control the device for sending and receiving SMS messages through instructions.
<3>Application method
) Direct use of instructions: Use instructions to drive the SMS module to send and receive SMS messages through the serial port. This is the lowest development mode and requires familiarity with the instructions of the SMS module
/> ) SMS Cat Development Kit: A secondary development kit based on serial port command integration by SMS Cat manufacturers. Developers only need to directly call SMS sending and receiving
) SMS Cat Communication Middleware: Based on a database interface provided by SMS Cat manufacturers The SMS sending and receiving background
service software is a more advanced SMS development solution.
<3>Development Architecture
) When SMS-related applications need to send SMS messages, they need to submit the SMS recipients and content to the SMS sending queue and read the received SMS messages from the SMS receiving queue.
) Software developers need to develop independent SMS background services, read SMS messages from the SMS sending queue, call the SMS Cat development kit to send SMS messages, and at the same time read the SMS messages received by the device by calling the SMS Cat development kit, and put SMS receiving queue
) The SMS mode development kit is actually connected to the SMS mode through serial communication, and the SMS module is driven by instructions to send and receive SMS messages.
Because SMS Modem is a serial communication device, text messages must be submitted serially for sending, and after submission, you must wait until there is a response before submitting the next one, otherwise it will cause SMS Modem to crash. Especially now that most applications are multi-user applications, if there are multiple threads operating the SMS module concurrently, it will also cause SMS Mode to crash. Even for the sending and receiving of the same SMS module, it must be serialized one after the other and cannot be operated by sending and receiving two concurrent threads. Therefore, it is recommended to use SMS queues. The common way is to use database tables.

Composition
SMS Cat has two parts: software and hardware. Many businesses now provide software and hardware. First, install the drivers and software provided by the merchant. Put the mobile phone card into the SMS modem and then connect it to the computer. After making relevant settings on the software, the software prompts that it has been connected to an SMS sending and receiving device. At this time, you can enter the sending content and sending number on the software, click the send button, and the software will automatically work to send the text message.
SMS Cat can also carry out secondary development through a variety of development applications such as middleware, middleware, database interfaces, controls, etc. Make your system have SMS function and make it more convenient for your work needs
