[0155] Simulation Example 1: Performance Enhancement in LTE-M

[0156] 1) Source model: the state change of the controlled equipment is provided by x(n+1)=Ax(n)+Bu(n)+w(n), n≥0, x(0)=0, where, x( n)∈R 4×1 , is the state processing of the controlled device, u(n)∈R 4×1 , is the control operation of the controlled device, and w(n)∈R 4×1 , is the Gaussian distribution of IID (independently distributed, independent identical distribution) with zero mean value and unit variance of the noise of the controlled equipment. We consider two cases. In Example A, the open-loop response of the dynamically controlled device is at (A,B)=(1.1I 4×4 ,I 4×4 ) is unstable, where, I 4×4 is a 4*4 identity matrix, such as figure 1 As shown in , the sensing device periodically senses the current state data x(n) and transmits it to the control device through LTE-M and NB LTE-M to form a stable closed-loop feedback. In Example B, the open-loop response of the dynamically controlled device stabiliz...

Abstract

The application discloses a transmission method of equipment status data, a sensing equipment and a control equipment. The transmission method includes: the sensing device acquires the current state data of the controlled device; determining the transmission mode of the current state data according to the control target of the controlled device; and using the transmission mode to control the controlled device The control device wirelessly sends or does not send each current status data. Through the above method, resource occupation and power consumption of the sensing device can be reduced.

Description

technical field [0001] The present application relates to the technical field of information transmission, especially the transmission method of equipment state data, sensing equipment and control equipment. Background technique [0002] Networked control system (Networked control system, NCS) is a fully distributed, networked real-time feedback control system, which is a collection of unstable controlled equipment and its sensing equipment, control equipment and communication network in a certain area. The sensing device detects the state information of the controlled device, and transmits the state information to the control device, so that the control device sends instructions to the controlled device according to the state information of the controlled device, so that the unstable controlled device can be stabilized. At present, NCS has been widely used in various fields such as industrial automation, intelligent transportation, remote robots and other fields. [0003] ...
