Example Embodiment
[0042] Embodiment 1: A DTU data transmission system, such as figure 1 Shown, including DTU and data acquisition equipment. DTU is connected with data acquisition equipment. The DTU includes a control module, and the control module has a pre-stored instruction set. When the control module runs the instruction set, it actively sends instructions to the data acquisition device, so that the data acquisition device transmits the collected data to the DTU. DTU sends the received data to the virtual IP server, and the virtual IP server transmits the data to the master station. DTU also includes enabling switches and clock circuits. The enable switch is connected with the control module, and the enable and disable of the instruction set is controlled by the enable switch. The clock circuit is also connected with the control module, and the cycle of the instruction set operation is controlled by the clock circuit. The DTU also includes a wireless module, which is respectively connect...
Example Embodiment
[0046] Embodiment 2: A method of using the above-mentioned DTU data transmission system to transmit data, the flow chart of the method is as follows image 3 As shown, the method includes the following steps:
[0047] In step A1, the instruction set is pre-stored in the control module, so that the instruction can be run through the control module when in use;
[0048] In step A2, start the control module and run the instruction set to facilitate the control of DTU to send instructions;
[0049] In step A3, the control module controls the DTU to send instructions to the data acquisition device so that the data acquisition device receives the instruction and performs data acquisition;
[0050] In step A4, the data acquisition device sends data to the DTU, and the data is converted and wirelessly transmitted through the DTU;
[0051] In step A5, DTU sends data to the virtual IP server;
[0052] In step A6, the virtual IP server sends data to the master station;
[0053] In step A7, if you w...
