The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to solve the problem that traffic signal lamps cannot normally maintain traffic order when a main control program is upgraded, the embodiment of the invention provides a main control program upgrading method of a traffic signal controller, which is applied to a main controller; the main controller is internally operated with 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 receiving the instruction of receiving the upgrade package, the preset monitor program starts to run the new main control program in the upgrade package to initialize the new main control program, where the initialization of the new main control program is a process of obtaining the execution state of the timing scheme of the current main control program before upgrading.
S202, a preset monitoring program receives an initialization completion instruction from a new main control program; the initialization completion instruction is used to indicate that the new main control program has completed initialization.
S203, after receiving the initialization completion instruction, the preset monitoring program sends an operation stopping instruction to the current main control program and sends an operation continuing instruction to the new main control program.
Specifically, any communication mechanism between the current main control program and the monitor program and between the monitor program and the new main control program can be adopted to realize communication, such as: shared memory, socket, message queue, semaphore or pipe, etc.
Therefore, according to the method for upgrading the main control program of the traffic signal controller, the running states of the current main control program and the new main control program are monitored through the preset monitoring program, so that the running of the current main control program and the initialization of the new main control program are executed in parallel, the current main control program is stopped to run after the initialization of the new main control program is completed, the new main control program is continued to run, the problem of yellow flashing of the signal lamp caused by restarting of the main control is avoided, and the traffic signal controller can still maintain normal traffic order in the upgrading process.
The specific flow of the monitoring program in the embodiment shown in fig. 2 will be described in detail by way of example.
Referring to fig. 3, fig. 3 is a specific flow chart of a monitor program in a method for upgrading a main control program of a traffic signal controller according to an embodiment of the present invention, where the specific flow chart includes:
s301, detecting whether a current running main control program exists; if not, executing step S302; if so, step S303 is performed.
S302, searching a main control program according to a preset path, taking the searched main control program as a current main control program, and starting operation.
In a specific embodiment, the monitoring program may be started first, and after the monitoring program is started successfully, if the current master control program running in the master controller is not available, the master control program is started by the monitoring program.
S303, detecting whether an upgrade package receiving completion instruction sent by the current main control program is received or not in the running process of the current main control program; if so, step S304 is performed.
S304, starting and running a new main control program in the upgrade package so as to initialize the new main control program.
In this step, the monitor program unpacks the new main control program in the upgrade package to the preset path, and then starts the new main control program to initialize it. The initialization process of the new master control program may be: initializing peripheral hardware, and detecting whether a specific memory area exists in a main controller; if yes, the operation information in the specific memory area is read; if not, a specific memory area for storing the operation information is created. 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 obtaining the operation information, and continuously control the color output of the signal lamp.
S305, judging whether an initialization completion instruction sent by a new main control program is received or not; 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, the embodiment of the invention provides a method for upgrading a main control program of a traffic signal controller, which is applied to a current main control program running in a main controller; the main controller also runs a preset monitoring program. Specifically, the method comprises the following steps:
s401, if an upgrade package is received in the running process, sending an upgrade package receiving completion instruction to a preset monitoring program; the upgrade package receives a completion instruction, and the completion instruction is used for indicating a preset monitoring program to start and run 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 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, any inter-process communication mechanism may be used to implement communication between the current main control program and the monitor program and between the monitor program and the new main control program.
Fig. 5 is a schematic flow chart of a main control procedure in the embodiment shown in fig. 4, including:
s501, initializing the peripheral.
After the main control program starts to run, the peripheral is initialized, and the parameters of the hardware are configured.
S502, detecting whether a specific memory area exists; if not, then step S503 is performed; if so, step S504 is performed.
S503, creating a specific memory area for storing the operation information, and then executing step S507.
In an application scenario, if no other main control program is running, that is, when the main control program is started for the first time, then there is no specific memory area in the main controller for storing running information, and at this time, the main control program may first create a specific memory area, such as a shared memory, for writing running information in a subsequent running process.
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 real time by the previous current main control program in the running process; and 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 scene, considering the variation of the 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 master control program to start running, the light color output of the signal lamp can be continuously controlled according to the timing scheme, and the running information includes but is not limited to: timing scheme number, timing scheme running state and phase number of signal lamp.
Specifically, the timing scheme refers to the output sequence and duration of each lamp color of the signal lamp in one signal period; the phase refers to the combination of lights and colors in several directions with right of way at the intersection in one signal period; the number for 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 lamplight color output sequence and the lamplight color output duration of the east-west signal lamp of the intersection are as follows: green light display 20s, yellow light flashing 3s, red light display 25s; the light color output in the north-south direction of the intersection and the duration are as follows: red light display 23s, green light display 22s, yellow light flashing 3s; the first phase is a lamp color combination with right of way and straight running in the east-west direction at the intersection, and the second phase is a lamp color combination with right of way and straight running in the north-south direction; the timing scheme running state refers to the position of the signal period in the timing scheme at the current moment.
Therefore, the main control program can continuously control the signal lamp according to the established timing scheme only according to the necessary operation information such as the timing scheme number, the timing scheme operation state and the phase number of the signal lamp, so that the availability and the continuity of the signal lamp are ensured.
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 or not; if so, step S507 is performed.
S507, normal operation is performed, and operation information is written into a specific memory area in real time.
S508, judging whether an upgrade package sent by the upper computer is received or not; if so, step S409 is performed.
S509, storing the upgrade package, and sending an upgrade package receiving completion instruction to a preset monitoring program.
S510, continuing normal operation.
S511, judging whether a stop operation instruction sent by the monitoring program is received; if so, step S512 is performed.
S512, releasing the resources and stopping the operation.
It should be noted that, in the master controller, both the current master control program to be upgraded and the new master control program in the upgrade package may start to operate according to the steps shown in fig. 5.
Obviously, compared with the related art, the method for upgrading the main control program of the traffic signal controller provided by the embodiment of the invention does not need to arrange two main controllers in the traffic signal controller, and can ensure that the main controllers can still normally maintain the traffic order during upgrading on the premise of not increasing the cost.
