Short message returning processing method

Abstract

The invention relates to a short message returning processing method for a remote control system. The remote control system comprises a sending device, a first communication gateway, a second communication gateway and a receiving device, wherein the sending device is connected with the first communication gateway; and the receiving device is connected with the second communication gateway. When the sending device transmits the short message to a far-end receiving device through a mobile communication network, the second communication gateway transmits a reply signal to the sending device after the receiving device receives the short message; if the sending device does not receive the reply signal within predetermined time, the receiving device is judged not to smoothly receive the replay signal, and the second communication gateway can transmit the replay signal again at the time or notify a manager; when the second communication gateway receives the short message, whether the short message is effective or not is judged; and if the short message is ineffective, the short message is stopped being transmitted to the receiving device. The invention can reduce the property and life injury of enterprises and personnel due to short message loss; and in addition, the gateways can prevent the conditions that repeated packets are continuously sent due to the failure of the sending device or the receiving device is occupied in bandwidth by an unknown short message due to hacker invasion.

Description

technical field [0001] The present invention relates to a short message return processing method for a remote control system, which uses a sending device to transmit a short message to a receiving device, and when the receiving device receives the short message, the second communication gateway connected to the receiving device transmits a reply signal To the first communication gateway connected to the sending device, this method can make the sending device confirm whether the receiving device has received the short message accurately, so as to reduce the damage to property and life caused by the loss of the short message to the enterprise and personnel. Background technique [0002] With the continuous development of communication technology, communication equipment has progressed from wired telephones and pagers to first-generation, second-generation and third-generation mobile phones, and these communication equipment have gradually changed from purely analog signal voice...

Problems solved by technology

[0003] The above-mentioned digital signal transmission methods include circuit switched data service (Circuit Swichted Data, CSD), short message service (Short Message Service, SMS) and general packet radio service (General Packet Radio Service, GPRS), etc. When using digital signals, it will occupy the resources of the voice channel, resulting in the situation that the digital signal cannot be transmitted online when making a phone call, or the phone cannot be made when the digital signal is transmitted online, and in some areas, this technology is not open for public use and has limitations. , regardless of whether it is using general wireless packet service or circuit switched data service, its cost is higher than that of short message service, so short message service has become a more commonly used digital transmission technology at present

[0004] However, this short message service technology does not have a security mechanism, that is to say, the sending device does not know whether the sent short message is successfully received by the specific receiving device. When the text message is received, it will cause quite serious damage, for example, it is used to monitor the rainfall or water level. When the rainfall or water level is abnormal, the remote end can use the text message to transmit back to the main control device inside the enterprise to perform relevant actions. If the main control equipment does not receive the signal due to busy lines or other reasons at this time, and the sending device does not know that the receiving device has not received the signal, this will prevent the enterprise from responding immediately, and the delay of this response will be It will cause serious casualties due to flooding. On the other hand, the monitoring of landslides used in mountainous areas may also cause the above irreparable damage because the sending device cannot know whether the receiving device has successfully received important information.
