On GPRS connection, the connection is carried out when data sending is set, the connection is normally in a disconnected state, in the aspect of a main pressure acquisition sensor, a pressure sensor with low power consumption is selected, the condition that the sensor reaches 1.5mW under the lowest power consumption is met, and the data safety mainly comprises two aspects: firstly, a plurality of servers can be simultaneously selected when the acquired data is sent, the acquired data is simultaneously sent, meanwhile, the data is stored locally, the data is not lost under the condition that the data is not sent successfully, and when the GPRS is connected again until the data is successfully sent, the data which cannot be successfully uploaded last time is reissued; secondly, if the low-power consumption telemetering terminal can not send data to the server for a long time, the Bluetooth device can be used for locally reading the data to ensure the safety of the data, and the convenience of the low-power consumption telemetering terminal comprises two aspects of remote parameter setting and local wireless data reading. The low-power consumption telemetering terminal can set parameters such as uploading time, data holding time, server IP, alarm telephone, alarm threshold value and the like to the terminal in a short message or GPRS mode in a normal mode without cooperation of field workers; in the aspect of local data reading, the low-power consumption remote measuring terminal can read local data by remotely waking up the Bluetooth mode and holding the Bluetooth equipment by field personnel, so that the data acquisition of the low-power consumption remote measuring terminal under the condition that the field personnel are inconvenient to contact is avoided.
