Dynamic load balancing telemetering method based on tabular configuration

Abstract

A dynamic load balancing telemetering method based on tabular configuration is used for performing observation data telemetering after required necessary functions are completed in each period in periodic tasks. The method comprises the following steps: (1.1) defining all telemetry data to be sent as a table form to form a telemetry data configuration and operation table; (1.2) traversing each rowin the table by using a periodic telemetry task generator, preparing telemetry data according to static configuration information of each row of telemetry data, configuring telemetry task parametersaccording to dynamic runtime information, and generating a telemetry task; (1.3) putting each telemetry task into a priority queue to be executed, and waiting for being executed; (1.4) defining a periodic telemetry task actuator, and calculating the remaining time of the period and the bus load rate of the past ts in each period; (1.5) calculating the number of executable telemetry messages, and taking out a corresponding number of telemetry tasks from the queue for execution according to the priority; and 1.6) the telemetry receiver sets a receiving cache and balances the peak bus load.

Description

technical field [0001] The invention relates to a dynamic load balancing telemetry method based on tabular configuration, which can be used in the realization of periodic telemetry functions and belongs to the technical field of measurement, control and control systems. Background technique [0002] Industrial measurement and control systems often monitor the operating status of the system. In most cases, the monitored data cannot be transmitted by wire, so the monitoring equipment usually sends the data to the telemetry equipment periodically, and sends it wirelessly to the remote receiving end through the antenna system. Due to the bandwidth limitation of the telemetry antenna system, the telemetry equipment often limits the load rate of the bus to which the monitoring equipment sends telemetry information to prevent the telemetry data from being overwritten by new incoming data before it is sent through the antenna, resulting in data loss. resulting in incompleteness and...

Problems solved by technology

[0004] The technical problem solved by the present invention is: to overcome the deficiencies and difficulties of the prior art, and propose a dynamic load balancing telemetry method based on tabular configuration. It realizes the high scalability of the telemetry solution. At the same time, by dynamically calculating the bus load and implementing a load balancing strategy based on this, the utilization rate of bus resources is greatly improved under the condition of satisfying the constraints of the bus load rate.
