Compared with the prior art, the broadcasting upgrading method of the street lamp terminal comprises the following steps: the concentrator and the street lamp terminal establish broadband power line carrier communication connection; the concentrator sends out an upgrade notification, and the street lamp terminal performs upgrade condition check; the concentrator divides the upgrade package into N upgrade fragments, and numbers and sends out each upgrade fragment; the concentrator sends out a query instruction, and the street lamp terminal compares the received upgrade sheet number with all the numbers of the upgrade fragments to obtain the number lacking the upgrade fragment and sends out the number lacking the upgrade fragment; the concentrator sends out the received upgrade fragments corresponding to the numbers of the missing upgrade fragments; the street lamp terminals sequentially merge, check and start up upgrading, and the regenerated upgrading report is sent to the concentrator. According to the method, the upgrading package is segmented and numbered through the concentrator, and then the effect of upgrading all street lamp terminals simultaneously is achieved through the mode of inquiring the supplementary package for multiple times. In addition, the upgrade notification and the query instruction are sent in a unicast mode, the upgrade fragments are sent in a broadcast mode, and different contents are respectively sent in the unicast mode and the broadcast mode, so that the reliability of the street lamp terminal in the upgrade process is improved, the integral upgrade time is shortened, the use and occupation of the bandwidth of broadband power line carrier communication are reduced, and the upgrade success rate is improved. Therefore, the invention also provides a broadcasting upgrading system, broadcasting upgrading equipment and a computer readable storage medium for optimizing a unicast upgrading mode, and the situation that the communication quality of broadcasting upgrading is occasionally bad is improved, the reliability of the street lamp terminal in the upgrading process is improved, the integral upgrading time is shortened, and the use and occupation of the bandwidth of broadband power line carrier communication are reduced, so that the upgrading success rate is improved.
While the invention has been described with respect to the above embodiments, it should be noted that modifications can be made by those skilled in the art without departing from the inventive concept, and these are all within the scope of the invention.
