Embodiment Construction

[0046] The present application is described in detail below in conjunction with the examples, but the present application is not limited to these examples.

[0047] see figure 1 , the embodiment of the present invention provides an industrial wireless network scheduling method based on loop power acquisition, the method includes:

[0048] 101. Determine the current working status of the node, and the working status includes sending status and receiving status;

[0049] Specifically, when there is no data packet to be forwarded in the node, it is determined that the current working state of the node is the receiving state; if there is a data packet to be forwarded in the node, it is determined that the current working state of the node is the sending state.

[0050] 102. Determine whether the remaining power of the node meets the energy consumption requirement according to the current working state of the node, if not, perform step 103; if yes, perform step 104;

Abstract

The application discloses an industrial wireless network scheduling method based on loop power supply. The method comprises the following steps: determining the current working state of a node, wherein the working state includes the sending state and the receiving state; judging whether the remaining capacity of the node meets the energy consumption demands according to the current working state of the node, and if not, continuously charging the node in the loop; if yes, awakening the node, and when the working state of the node is the receiving state, receiving a data packet at the preset receiving time slot; and when the working state of the node is the sending state, sending the data packet at the preset sending time slot. According to the embodiment of the invention, the problem of insufficient node power can be fundamentally solved by using the loop power supply mode, the life time of long-period industrial wireless networks can be prolonged, the loop power supply mode has high reliability, and thus the reliability of data transmission in the wireless networks can be improved.

Description

technical field [0001] The present application relates to an industrial wireless network scheduling method and device based on loop power acquisition, which belongs to the field of industrial wireless network scheduling. Background technique [0002] The industrial wireless network is a wireless network structure integrating detection and control composed of gateways, network controllers, and a large number of wireless sensor nodes. Compared with traditional control systems, industrial wireless networks have high reliability, flexible deployment, and low cost, so they are widely used. [0003] At present, the wireless sensor nodes in the industrial wireless network are mainly powered by their own batteries. When the power is sufficient, the industrial network can achieve high real-time transmission. However, due to the small size of sensor nodes, the amount of power they carry is very limited. As the number of nodes in the network run out of power increases, or the power of...
