Problems solved by technology
[0003] However, the reliability of remote upgrade is not high, and it is prone to failure, which will cause the traffic signal controller to fail to control traffic normally, and may even cause traffic accidents
If an abnormality occurs during the upgrade process and the upgrade fails, it will be difficult for the traffic signal controller to re-upgrade again, and maintenance personnel must go to the site to solve the problem
The above two types of problems seriously limit the application and implementation of remote program upgrades for traffic signal controllers

The invention discloses a method and device for remotely upgrading a traffic signal controlling machine. The method comprises the steps of obtaining an upgrade instruction, sending a first instructionto a second master controller and replacing the second master controller to control the light color output of signal lamps by a first master controller, wherein the first instruction is used for instructing the second master controller to stop working and wait for program upgrade; obtaining an upgrade program sent by a control center, storing the upgrade program in a first program memory and notifying the second master controller to restart, wherein the first program memory is a memory which can be accessed by both the first master controller and the second master controller; and when determining that the second master controller is successfully started, notifying the second master controller to control the light color output of the signal lamps. According to the method, a standby mastercontroller is used to replace a main master controller to control the light color output of the signal lamps in the program upgrading process, so that the situation that a traffic signal controller cannot work in the program upgrading process can be avoided.
Description
technical field [0001] The embodiments of the present invention relate to the field of traffic technology, and in particular to a method and device for remotely upgrading a traffic signal controller. Background technique [0002] Since the installation locations of the traffic signal controllers are dispersed and spread all over the city, if the software program of the traffic signal controllers needs to be changed, the maintenance personnel go to the site to upgrade the traffic signal controllers one by one, which takes a lot of time and effort. The upgrade program is sent remotely to each traffic signal controller to be upgraded, and the way of automatic upgrade by the traffic signal controller is the most ideal. [0003] However, the reliability of remote upgrade is not high, and it is prone to failure, which will cause the traffic signal controller to fail to control traffic normally, and may even cause traffic accidents. If an abnormality occurs during the upgrade proc...
