Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit indication of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.
With the rapid development of urban construction and traffic industry, the technical requirements on the traffic safety information display system are higher and higher. Most of the current traffic information display systems are fixedly arranged. Because no traffic command easily causes traffic accidents on road sections with traffic accidents or road finishing, the movable traffic signal lamp appears and can be temporarily applied to road sections needing traffic command.
After the lamp heads of the traffic lights are turned on, the traffic lights are matched with the handheld controller for controlling the lamp heads of the traffic lights, and because the handheld controller can only receive the information of one traffic light lamp head at the same time, when the two traffic light lamp heads simultaneously send signals to the handheld controller, signal collision is easily caused.
The following detailed description is provided to the technical solutions of the present application and how to solve the above technical problems with the technical solutions of the present application in combination with specific embodiments, and the following embodiments may be combined with each other, and are not repeated in some embodiments for the same or similar probabilities or processes, and the embodiments of the present application will be described below with reference to the accompanying drawings.
In one embodiment, as shown in fig. 1, a flow chart of a computing method for resolving parallel code sending collision by using a random number is specifically provided. The method is mainly applied to traffic light heads, and the specific method comprises the following steps:
step 101: and reading the ID of the lamp cap of the traffic light, and storing the ID into an ID array.
In the embodiment of the application, the traffic light head can be a movable traffic signal light. When the traffic light head is produced, production equipment personnel write the ID of each traffic light head into the traffic light head, wherein the ID can be the ID which only represents the traffic light head and can be composed of a plurality of characters.
Specifically, the traffic light head reads the ID information of the traffic light head and stores the ID information of the traffic light head into an ID array. The ID of the traffic light head can be set according to specific conditions during production, for example, the ID can be composed of 12 characters, an array is generated by the characters, and the array is stored in the ID array.
Step 102: and generating a check value according to the ID array.
Specifically, the check value is obtained through a certain operation to check the correctness of the group of data, in the embodiment of the application, the check value corresponding to the traffic light head ID is generated according to CRC-16, and CRC-16 is a cyclic redundancy check and is a hash function for generating a short fixed-number check code according to data.
Step 103: and obtaining the interval time of the traffic light head according to the verification value.
Specifically, the verification value is divided by 100, and then 500 is added to obtain the interval time of the lamp cap of the traffic light. The time interval of the traffic light head in the embodiment of the application is one time interval in milliseconds. Because the IDs set during production of each traffic light head are different, the obtained ID arrays are also different, and the check values generated according to the ID arrays are different, so that the interval time of each traffic light head calculated according to the check values of each traffic light head is also different.
Step 104: and sending the ID to the handheld controller according to the interval time.
Specifically, the handheld controller is a controller capable of controlling the lamp head of the traffic light within a certain range. And after the interval time of each traffic light head is calculated, each traffic light head sends an ID to the handheld controller according to each interval time and establishes connection with the handheld controller. Because the calculated interval time of each traffic light head is different, the interval time of all traffic light heads in a certain range transmitting IDs to the handheld controller is different. In the embodiment of the application, the handheld controller can control the traffic light head connected with the handheld controller within 1.6 kilometers. By calculating the time interval of each traffic light head and staggering the time of sending the ID to the handheld controller by all the traffic light heads in a millisecond interval time intervention mode, the signal blockage caused when a plurality of traffic light heads send signals to the handheld controller at the same time can be effectively prevented.
Referring to fig. 2, on the basis of the foregoing embodiments, as an optional embodiment, a method for calculating a random number solution for a parallel code sending collision further includes:
step 201: and sending the ID to the handheld controller according to the interval time, and judging whether the response to the handheld controller is received or not in the interval time.
Specifically, after each traffic light head is turned on, the traffic light head starts to be paired with the handheld controller, and the specific pairing process refers to the steps 101 to 105, and sends the ID to the handheld controller according to the calculated interval time of each traffic light head. A determination is made during the interval as to whether a response, which may be in the form of a signal, is received to the handheld controller.
Step 202: if a response to the handheld controller is received, the ID is no longer sent to the handheld controller.
Specifically, if the traffic light head receives a response to the handheld controller, that is, the traffic light head and the handheld controller are successfully paired, the handheld controller does not send the ID to the handheld controller any more. And the traffic light head which is successfully paired at each time does not send the ID to the handheld controller any more, so that the sending amount of the ID sent by the traffic light head to the handheld controller is less and less, and the probability of collision is further reduced.
Step 203: and if the response to the handheld controller is not received, updating the check value, and executing the step of obtaining the interval time of the traffic light head according to the check value until the response to the handheld controller is determined to be received in the interval time.
Specifically, if no response to the handheld controller is received, adding the last two bytes of the ID array of the traffic light head to the upper 8 bits and the lower 8 bits of the check value to generate a new ID array, generating a new check value corresponding to the new ID array according to the CRC-16 algorithm, replacing the previous check value with the new check value, dividing the new check value by 100, adding 500 to obtain a new time interval of the traffic light head, and continuing to judge whether to receive the response to the handheld controller by the traffic light head until the response to the handheld controller is determined within the interval time, i.e., all traffic light heads within a certain range can be completely paired one by one. In the embodiment of the application, the traffic light head successfully matched first can be used as a master, the traffic light head successfully matched subsequently can be used as a slave, and in other feasible embodiments, the master and the slave can be selected by a user.
On the basis of the foregoing embodiments, as an optional embodiment, a method for calculating a random number solution to a parallel code-sending collision further includes:
in one possible embodiment, the traffic light head is in wireless communication with the manager terminal device. And if the traffic light head is not successfully matched within the preset times, indicating that the traffic light head is possible to have a fault, and sending the ID of the traffic light head to the terminal equipment of a manager so that a professional can carry out maintenance. The traffic light head is provided with a camera which can be used for monitoring the traffic flow of the road section and the running condition of vehicles on the road surface. The general traffic light lamp heads are arranged at the crossroad, if the first traffic light lamp head corresponds to a first road and the second traffic light lamp head corresponds to a second road, if the traffic flow of the first road is monitored to be far greater than the traffic flow of the second road in a certain time period, the duration of increasing the green light of the first traffic light lamp head can be prolonged, and therefore the duration of corresponding to the green light of the second traffic light lamp head can be correspondingly reduced. For example, at an intersection of two roads, in a certain time period every day, the traffic flow of the first road is always far greater than the traffic flow of the second road, and then the time lengths of the traffic lights of the first traffic light head and the second traffic light head can be adjusted to increase the traffic efficiency of vehicles at the intersection.
Fig. 3 is a schematic flowchart illustrating an exemplary process of a method for calculating a solution to a parallel code-sending conflict by using a random number according to an embodiment of the present application. The implementation principle of the exemplary embodiment is as follows: and when the traffic light lamp cap receives and reads the ID written in the traffic light lamp cap during production, the ID is stored in a corresponding PL-ID-crc array, the ID of each traffic light lamp cap is different, a crc check value is generated according to the number of the ID groups of each traffic light lamp cap, the crc check value is divided by 100, and the interval time is obtained by adding 500, and the traffic light lamp cap judges whether the response of the handheld controller is received. If the response to the handheld controller is received within the interval time, the self ID is not sent to the handheld controller any more, and the traffic light head and the handheld controller are successfully matched; if no response to the handheld controller is received in the interval time, after the interval time, adding the last two bytes of the PL-ID-crc array to the upper 8 bits and the lower 8 bits of the crc value to generate a new array, generating a new crc value according to the new array, returning to continuously execute the step of dividing the new crc value by 100 and adding 500 to obtain the interval time, and judging whether the response to the handheld controller is received by the traffic light head until the response to the handheld controller is received in the interval time. According to the embodiment of the application, the interval time of sending the ID to the handheld controller by the traffic light lamp cap is calculated and controlled, the time of sending the ID to the handheld controller by the traffic light lamp caps is staggered, namely the code sending time of the traffic light lamp caps is automatically adjusted to stagger the matching time point with the handheld controller, and signal blockage is effectively prevented when the traffic light lamp caps send signals to the handheld controller simultaneously.
