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 period.

[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.

Abstract

The invention discloses a method for improving communication efficiency by improving equipment polling mode in the technical field of computers. The method includes: assigning an address to each slave device for use when the master device polls; the master device polls all slave devices connected to the master device within a round of polling period, and judges whether there is any slave device not connected to the master device. The connected slave device, if it is, polls the unconnected slave device; then judges whether the master device receives the response from the polled unconnected slave device, if so, the master device marks the slave device as connected Slave device; after one poll is completed, the next poll is performed. The invention improves the communication flow occupied by polled slave devices, reduces the waste of bandwidth and improves the communication efficiency.

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...
