Problems solved by technology

The above-mentioned communication methods have their own advantages and disadvantages. For example, the wired network has low communication cost and strong ability but high construction cost; although the ground cellular network is mature in technology, it cannot achieve seamless coverage due to the high construction cost for sparsely populated or wild areas; the local area network has strong transmission capacity and low tariff. Small coverage area cannot achieve long-distance transmission; although satellite network has large coverage area, it is expensive to use
To sum up, there are some power equipment in areas where the signal of the above-mentioned communication methods is not covered or the signal is weak. If the satellite communication method with the largest coverage is used, the communication cost will be high.

Embodiment 1

[0027] see figure 1 , an ad hoc network transmission device, comprising: a control module, an ad hoc network module, a cellular mobile module, a satellite module, and an I / O interface;

[0028] The ad hoc network module uses the ad hoc antenna to receive or send data to other ad hoc network modules;

[0029] The cellular mobile module (specifically the 4G module in this embodiment) utilizes the 4G antenna to receive or send data to the grid monitoring platform;

[0030] The satellite module uses the satellite antenna to receive or send data to the grid monitoring platform;

[0031] The I / O interface is electrically connected to various sensors (such as temperature sensors, humidity sensors, and wind speed sensors) to receive sensor data; the control module communicates with the ad hoc network through the I / O data line and the I / O control line, and the I / O The O interface is electrically connected, respectively communicated with the cellular mobile module and the satellite mo...

Embodiment 2

[0035] Assuming that the ad hoc network module is receiving data and the device is within the range of 4G network and satellite network signals, then the control module controls the array switch to communicate with the 4G communication module through the I / O control signal, and transmits data through the 4G network; if the 4G network is lost, then the control module The module further detects the size of the I / O data. If the I / O data is large data (such as video, pictures), the control module will cache the data locally and transmit it after the 4G network is restored. If the I / O data is small Data, then the control module will control the switch array through the I / O control signal to connect the satellite module, and transmit the small data of the Internet of Things to the power grid monitoring platform through the satellite network.

Embodiment 3

[0037] Different devices in the power system have different requirements for real-time data. For example, the monitoring equipment that detects the installation status of the line collects pictures of the line at regular intervals; Then, the priority order of the Internet of Things devices connected to the I / O interface is preset in the control module, and the data from the Internet of Things devices are sent according to the priority order.

[0038] The beneficial effect of this embodiment is that the data of devices requiring real-time data is sent preferentially, and the high requirements of some devices for real-time performance are met without additional communication cost.

Description

technical field [0001] The invention relates to an ad hoc network transmission device, which belongs to the field of power grid communication terminals. Background technique [0002] Power equipment is widely distributed, some of which are distributed in places where human eyes are scarce and maintenance personnel are difficult to reach. The device status data needs to be transmitted regularly or in real time through the communication terminal. At present, most communication terminals on the market have one to three communication methods, such as wired communication for wide area network, 4G\5G for terrestrial cellular network, wifi\Bluetooth\lora for LAN communication, KA\KU\Tiantong for satellite network and other satellite links. The above-mentioned communication methods have their own advantages and disadvantages. For example, the wired network has low communication cost and strong ability but high construction cost; although the ground cellular network is mature in te...
