Description

Communication optimization method and device of GPRS code scanning device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a communication optimization method and apparatus for a GPRS code scanning apparatus.

Background

In the prior art, the conventional communication technology generally has the problem of co-frequency interference, that is, when communication is performed on the same frequency band channel (channel) and signals are transmitted simultaneously, a receiver often causes the received signals to be interfered, or causes communication data to be blocked/queued, or even does not receive any signal. In order to solve such problems, some manufacturers currently adopt a coordinator solution, i.e., a coordinator is used to allocate timing transmission or reception, which results in a significant increase in cost.

Another solution in the market is to distinguish information of the same communication frequency band by means of coding addresses, and then load data information to be communicated, so as to realize marking and identification of the data information. However, the communication speed of this solution is relatively slow, mainly because when multiple devices communicate, the communication data may be blocked/queued, and the receiver may be interfered or may not receive any signal. In addition, the information of the same communication frequency band is distinguished in an address coding mode, and the receiving address mark is easy to change or fail along with the time, so that the signal cannot be received or the equipment loses contact.

Therefore, the effectiveness of prompting that the GPRS code scanning device can work normally is improved.

And step 104, establishing a communication channel with the base station according to the communication connection threshold value and the base station connection success rate which are acquired in advance.

And step 106, if the connection power of the GPRS code scanning device and a communication connection threshold of a base station and the base station is higher than a preset threshold, dividing the communication frequency band into at least two narrow-band communication frequency bands for communication.

Wherein, the calculation of the GPRS code scanning device and a base station communication connection threshold value comprises the following steps: acquiring the electricity utilization habit of the GPRS code scanning device, and acquiring a first compensation value according to the electricity utilization habit; and calculating to obtain a communication connection threshold value according to the first compensation value, the GPRS current electric quantity value and the received communication signal value.
