A Realization Method of Multi-channel Arbitrary Timer

Abstract

The invention relates to the field of network communication timing, in particular to an implementation method of a multi-channel random timer. The implementation method comprises the steps that a read-write control module controls reading of timing count data stored in a storage module and timing configuration data stored in a timing configuration module, and the timing count data are compared with the timing configuration data; an accumulation module adds one to the timing count data, and then the read-write control module rewrites the timing count data into the storage module to replace original timing count data; a timing judgment module outputs timing signals, the accumulation module conducts zero clearing on the timing count data at the same time, and then the timing count data are rewritten into the storage module again through the read-write control module and replace the original timing count data. By the adoption of the implementation method of the multi-channel random timer, when specific timing is needed in the communication process, random timing duration of any channel can be obtained just by adopting system configuration and modifying the timing configuration data in the timing configuration module, and therefore system debugging is facilitated; even if the design of a system is completed, flexible and convenient adjustment can be conducted, so that redesign of the system is avoided.

Description

technical field [0001] The invention relates to the field of network communication timing, in particular to a method for realizing a multi-channel arbitrary timer. Background technique [0002] In communication systems, a large number of timers are often required to complete multi-channel timeout alarms. For example, for multi-channel signaling monitoring, a series of messages are sent and received on the channel at regular intervals. If the message is sent and received normally, the channel is normal. If the message is abnormal, it needs to re-detect or send an alarm message. Depending on the channel, the signaling sending and receiving cycle is different. If the signaling sending and receiving time is too long, channel faults cannot be found in time, and channel protection processing is not timely, causing communication failures; if the signaling sending and receiving time is too short, the channel utilization rate will be greatly reduced. Sending and receiving signaling ...

Problems solved by technology

Depending on the channel, the signaling sending and receiving cycle is different. If the signaling sending and receiving time is too long, channel faults cannot be found in time, and the channel protection processing is not timely, causing communication failures; the signaling sending and receiving time is too short, and the channel utilization rate is greatly reduced. Sending and receiving signaling in a short time will occupy a large frequency bandwidth, and the efficiency of the communication system will be greatly reduced

[0003] In the communication system, the sending and receiving time of signaling is often fixed at several times, such as 3.3ms, 10ms, 1s, etc., but for some special signaling, this sending and receiving time is not suitable. When changing the sending and receiving time, it is difficult to change the system configuration parameters
