Background
A traffic signal controller is a device for controlling traffic signal lights. The main controller is an important hardware component of the traffic signal controller, and can issue a control command according to a preset timing scheme by running a main control program to control the light color output of the signal lamp.
In order to repair errors or complete functions, the master control program in the traffic signal controller is often required to be upgraded. However, the upgrading process may cause a long unavailable time for the signal lamp, and therefore, a main controller and a standby main controller are usually provided in the traffic signal controller at the same time.
Specifically, the upgrading process of the traffic signal controller is shown in fig. 1: after receiving the upgrade instruction, the standby master 110 sends an instruction of stopping working and waiting for upgrade to the master 120; then, the standby main controller 110 receives the current light color output scheme and the execution state of the current light color output scheme sent by the main controller 120, takes over the control of the light color output of the signal lamp by the main controller 120, obtains an upgrading program, and stores the upgrading program in the memory 130 accessible to both the main controller 120 and the standby main controller 110; finally, standby master 110 sends a reset command to master 120, causing master 120 to read the upgrade program from memory 130 and restart.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problem that the traffic signal lamp cannot normally maintain the traffic order when the master control program is upgraded, the embodiment of the invention provides a master control program upgrading method of a traffic signal controller, which is applied to a master controller; the main controller runs a current main control program and a preset monitoring program. Specifically, as shown in fig. 2, the method includes:
s201, in the running process of the current main control program, if a preset monitoring program receives an upgrade package receiving completion instruction sent by the current main control program, starting to run a new main control program in the upgrade package.
In this step, after the preset monitoring program receives the update package reception completion instruction, the new main control program in the update package is started to be operated to initialize, and the initialization of the new main control program is a process of acquiring the execution state of the timing scheme before the current main control program is updated.
S202, the preset monitoring program receives an initialization completion instruction from the new main control program; the initialization completion instruction is used to indicate that the new master program has completed initialization.
And S203, after receiving the initialization completion instruction, the preset monitoring program sends an operation stop instruction to the current main control program and sends an operation continuing instruction to the new main control program.
Specifically, any one of the interprocess communication mechanisms may be adopted to implement communication between the current main control program and the monitor program and between the monitor program and the new main control program, for example: shared memory, sockets, message queues, semaphores or pipes, etc.
It can be seen that, in the method for upgrading the main control program of the traffic signal controller according to the embodiments of the present invention, the preset monitoring program is used to monitor the running states of the current main control program and the new main control program, so that the running of the current main control program and the initialization of the new main control program are executed in parallel, and after the initialization of the new main control program is completed, the current main control program is stopped and the new main control program is continuously run, thereby avoiding the yellow flashing problem of the signal lamp caused by the restart of the main controller, and enabling the traffic signal controller to still maintain the normal traffic order during the upgrading process.
The following describes a specific flow of the monitoring program in the embodiment shown in fig. 2 in detail by way of example.
Referring to fig. 3, fig. 3 is a schematic view of a specific flow of a monitoring program in a method for upgrading a master control program of a traffic signal controller according to an embodiment of the present invention, where the method includes:
s301, detecting whether a running current main control program exists; if not, executing step S302; if so, step S303 is performed.
S302, searching the main control program according to a preset path, taking the searched main control program as the current main control program, and starting to operate.
In a specific embodiment, the monitoring program may be started first, and after the monitoring program is started successfully, if there is no current main control program in the main controller, the main control program is started by the monitoring program.
S303, in the running process of the current main control program, detecting whether an upgrade package receiving completion instruction sent by the current main control program is received; if so, step S304 is performed.
And S304, starting and running the new main control program in the upgrade package so as to initialize the new main control program.
In this step, the monitoring program unpacks the new master control program in the upgrade package to a preset path, and then starts the new master control program to initialize. The initialization process of the new master program may be: initializing peripheral hardware, and detecting whether a specific memory area exists in a main controller; if yes, reading the operation information in the specific memory area; and if not, creating a specific memory area for storing the operation information. The running information in the specific memory area can be written in real time by the current main control program in the running process.
It can be understood that the specific memory area is used for temporarily storing the operation information of the current main control program, so that the new main control program can restore the operation state of the current main control program after acquiring the operation information and continuously control the light color output of the signal lamp.
S305, judging whether an initialization completion instruction sent by a new main control program is received; if so, step S306 is performed.
S306, sending an operation stopping instruction to the current main control program, and sending an operation continuing instruction to the new main control program.
As shown in fig. 4, an embodiment of the present invention provides a method for upgrading a master control program of a traffic signal controller, which is applied to a current master control program running in a master controller; the main controller is also internally provided with a preset monitoring program. Specifically, the method comprises the following steps:
s401, if an upgrade package is received in the operation process, sending an upgrade package receiving completion instruction to a preset monitoring program; the upgrade package receives a completion instruction for instructing a preset monitoring program to start and operate a new main control program in the upgrade package.
S402, receiving a stop operation instruction sent by a preset monitoring program, and stopping operation; the stop operation instruction is used for indicating that the preset monitoring program has received the initialization completion instruction from the new main control program.
In this embodiment, communication between the current main control program and the monitoring program and between the monitoring program and the new main control program may also be implemented by using any communication mechanism between processes.
Fig. 5 is a schematic flowchart of a specific flow of the main control program in the embodiment shown in fig. 4, including:
s501, initializing the peripheral.
After the master control program is started to run, the peripheral equipment is initialized, and parameters of used hardware are configured.
S502, detecting whether a specific memory area exists or not; if not, go to step S503; if so, step S504 is performed.
S503, a specific memory area for storing the operation information is created, and then step S507 is performed.
In an application scenario, if no other main control program runs, that is, when the main control program is started for the first time, a specific memory area for storing running information does not exist in the main control program, and at this time, the main control program may create a specific memory area, such as a shared memory, for writing the running information in the subsequent running.
S504, the operation information in the specific memory area is read.
Here, when the main control program is the current main control program to be upgraded, the running information in the specific memory area may be written in by the last current main control program in real time during the running process; when the main control program is a new main control program in the upgrade package, the running information in the specific memory area may be written in real time by the current main control program to be upgraded.
In an actual application scenario, in consideration of the change of traffic flow in different time periods, a plurality of timing schemes are often designed even for the same intersection. Therefore, in order to enable the main control program to continue to control the light color output of the signal lamp according to the timing scheme after starting operation, the operation information includes but is not limited to: the timing scheme number, the timing scheme running state and the phase number of the signal lamp.
Specifically, the timing scheme refers to the output sequence and duration of each light color of the signal lamp in one signal period; the phase refers to the combination of the light colors in several directions with the right of way at the intersection in one signal period; the numbering of these combinations is the phase number.
Fig. 6 is an exemplary diagram of a traffic signal timing scheme according to an embodiment of the present invention. As shown in the figure, the signal period of the timing scheme is 48s, and in one signal period, the light color output sequence and the time length of the east-west directional signal lights at the intersection are as follows: green light display for 20s, yellow light flashing for 3s, and red light display for 25 s; the color output and the time length of the lights in the south and north directions of the intersection are as follows: red light display 23s, green light display 22s, yellow light flashing 3 s; the first phase is the light color combination of the straight going in the east-west direction with the traffic right at the intersection, and the second phase is the light color combination of the straight going in the north-south direction with the traffic right; the timing scheme operation state refers to the position of the current time in the signal period of the timing scheme.
Therefore, the main control program can continuously control the signal lamp according to the set timing scheme as long as necessary operation information such as the timing scheme number, the timing scheme operation state and the phase number of the signal lamp is required, and the availability and the continuity of the signal lamp are ensured.
And S505, sending an initialization completion message to a preset monitoring program.
S506, judging whether a continuous operation instruction sent by the monitoring program is received; if so, step S507 is executed.
And S507, normally operating, and writing the operation information into the specific memory area in real time.
S508, judging whether an upgrade package sent by an upper computer is received; if so, step S409 is performed.
S509, storing the upgrade package, and sending an upgrade package receiving completion instruction to a preset monitoring program.
And S510, continuing normal operation.
S511, judging whether an operation stopping instruction sent by the monitoring program is received; if so, step S512 is performed.
S512, releasing the resources and stopping running.
It should be noted that, in the master controller, whether the current master control program to be upgraded or the new master control program in the upgrade package may be started and operated according to the steps shown in fig. 5.
Obviously, compared with the related art, the method for upgrading the master control program of the traffic signal controller provided by the embodiment of the invention does not need to arrange two master controllers in the traffic signal controller, and can enable the master controllers to still normally maintain the traffic order during upgrading on the premise of not increasing the cost.

Firstly, in the running process of a current main control program, if a preset monitoring program receives an upgrade package receiving completion instruction sent by the current main control program, starting to run a new main control program in an upgrade package; then, the preset monitoring program receives an initialization completion instruction from the new main control program; the initialization completion instruction is used for indicating that the new main control program is initialized; and after receiving the initialization completion instruction, the preset monitoring program sends a stop operation instruction to the current main control program and sends a continuous operation instruction to the new main control program.
