SMS backhaul processing method

The present invention relates to a method for processing a short message backhaul, which uses a transmitting device to transmit a short message to a receiving device. When the receiving device receives the short message, the second communication gate connected to the receiving device transmits a reply signal to the transmitting device. The first communication gate enables the transmitting device to confirm whether the receiving device accurately receives the newsletter, thereby reducing damage to the property and life caused by the loss of the newsletter to the enterprise and personnel.

According to the continuous development of communication technology, communication equipment has evolved from wired telephones and pagers to mobile phones of the first, second and third generations, and these communication devices have gradually changed the original analog signal transmission. The digital signal transmission method has been added, which has expanded the user's diversified communication style. Due to the advancement of mobile communication technology, the base station setting has become more and more popular, and industrial control equipment has begun to use the mobile communication network to execute the remote end.

In some areas, the technology is not open for public use. There are limitations, and whether it is the use of general wireless packet services or circuit-switched data services, the cost is relatively short, so the short-message service becomes the more commonly used digital transmission technology.

However, such a short message service technology does not have a security mechanism, that is to say, the transmitting device does not know whether the sent short message is successfully received by a specific receiving device. Thus, when the transmitting device sends an alert message, the receiving device does not go smoothly. When receiving the newsletter, it will cause considerable damage, such as monitoring of rainfall or water level. When the rainfall or water level is abnormal, the remote end can use the short message to transmit back to the internal control device of the enterprise to perform related actions.
