Problems solved by technology

The transmission method of this scheme adds Beidou short messages on the basis of the ground communication network. However, the acquisition of high-precision position information still relies on the ground communication network to achieve dynamic differential technology, so it is still not suitable for natural disasters, frequent occurrences, and public networks. Areas with unstable signals have greater limitations
[0004] In summary, the tower tilt monitoring terminal in the prior art relies on the ground communication network, and is not suitable for areas where natural disasters are prone to occur frequently and public network signals are unstable

Embodiment 1

[0040] Such as Figure 1 to Figure 3 As shown, the tower status monitoring terminal based on Tiantong link and 4G network dual-mode communication includes: a main processor integrated on the main control board, an inclination sensor, a power conversion module, and a high-precision positioning system electrically connected to the main control board Module, 4G communication module, Tiantong module, lithium battery, solar panel (both lithium battery and solar panel are electrically connected to the main control board through the power supply interface), the Beidou antenna electrically connected to the high-precision positioning module, and electrically connected to the 4G communication module The 4G antenna is the Tiantong antenna that is electrically connected to the Tiantong module. There is also a debugging interface on the main control board.

[0041] In this embodiment, the main control board, high-precision positioning module, 4G communication module, Tiantong module and l...

Embodiment 2

[0051] Further, the main processor analyzes the state of the tower according to the following formula according to the tilt angle data and high-precision position data:

[0052] T3=(A>A3)||(B>B3);

[0053] T2=(!T3)&&((A>A2)||(B>B2));

[0054] T1=((!T2)||(!T3))&&(A>A1)||(B>B1);

[0055] T0=(0

[0056] Among them, A is the tangent value of the inclination angle of the tower, A1, A2, and A3 are the three preset inclination angle thresholds; B is the displacement value of the tower, and B1, B2, and B3 are the three preset displacement thresholds; when T0=1, The state of the tower is a safe state; when T1=1, the state of the tower is a normal state; when T2=1, the state of the tower is a serious state; when T3=1, the state of the tower is an emergency state.

[0057] In this embodiment: A1=0.02; A2=0.06; A3=0.1; B1=12.7mm; B2=19.05mm; B3=25.4mm.

[0058] Assume that the current state of the tower is a safe state, and the data return cycle is set to 1h in the ma...

Embodiment 3

[0063] Further, within the data sending cycle, the Tiantong module sends the tilt angle data to the remote monitoring platform for 5 consecutive times; the remote monitoring platform returns the handshake message after receiving it 3 times or more; if the Tiantong module receives the handshake message , then stop the data sending in this period, otherwise, the Tiantong module will continue to send data after an interval of 30s.

[0064] When Tiantong Satellite transmits data, there are problems such as data transmission delay and data packet loss. The improvement of this embodiment is that, by setting the handshake mechanism, the remote monitoring platform can know in time whether the data is successfully delivered. At the same time, the Tiantong module sends the tilt angle data 5 times in a row, and the remote monitoring platform sends a handshake message after receiving it 3 times, which can prevent data loss and cause errors, and improve the communication efficiency and acc...
