Embodiment Construction

[0017] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0018] figure 1 It is a flow chart of the method for improving communication efficiency by improving device polling in the present invention. figure 1 In, the realization process of the present invention is:

[0019] Step 1: Assign an address to each slave device for polling by the master device.

[0020] Step 2: The master device polls all slave devices connected to the master device within a polling cycle.

[0021] Step 3: During the polling period, determine whether there is a slave device not connected to the master device, if yes, perform step 4; otherwise, return to step 2 for the next round of polling.

[0022] Step 4: Poll the unconnected slave.

[0023] Step 5: Determine whether the master device has rece...

Abstract

The invention discloses a method for improving communication efficiency by improving an equipment polling mode, which belongs to the technical field of computers. The method comprises the following steps: allocating an address for each secondary equipment for the polling of the primary equipment; polling the secondary equipment connected with the primary equipment in a polling period by the primary equipment, judging whether secondary equipment is not connected with the primary equipment, and polling the unconnected secondary equipment if secondary equipment is not connected with the primary equipment; judging whether the primary equipment receives a response of the polled secondary equipment which is not connected, and marking the secondary equipment as the connected secondary equipment by the primary equipment if the response is received; and performing the next polling process after one polling process is finished. Through the method, the communication traffic occupied by the polled secondary equipment is improved, the waste of bandwidth is reduced and the communication efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method for improving communication efficiency by improving equipment polling mode. Background technique [0002] In the traditional point-to-multipoint communication process, the master device is usually used to poll all slave devices sequentially. When the number of slave devices managed by the master device is large and the number of slave devices mounted on the bus is relatively small, this polling method often causes the slave devices to wait for a long time; and each slave device occupies If the communication traffic is too low, bandwidth will be wasted. Therefore, the communication efficiency of the commonly used polling method is usually very low. Contents of the invention [0003] The object of the present invention is to propose an improved device polling method to improve the communication efficiency in the device polling process, aiming at the probl...
