Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit, and in particular to a broadcast system control method, device, equipment and storage medium. BACKGROUND

[0002] The rail transit line usually uses an integrated dispatching system to monitor the device state of each subsystem and issue corresponding remote control, telemetry and other control instructions. The control of the broadcast system (PAS) is mainly realized through an integrated dispatching broadcast module, such as issuing pre-recorded broadcast, oral broadcast, monitoring and other instructions, so as to realize real-time broadcasting and intercom for the platform or train. After issuing the corresponding instructions, the broadcast system should feed back the execution state of the corresponding broadcast partition. However, the integrated dispatching broadcast module can only feed back whether the instruction is executed, and cannot accurately and specifically feed back the execution state of a specific partition. Therefore, using the current feedback mechanism has the following disadvantages:

[0003] 1. The feedback result of instruction execution is not accurate. Although multiple broadcast partitions are selected to issue instructions, the final feedback is only whether the instruction is executed, and cannot be specific to which broadcast partitions have been executed. The feedback message is too vague, which can easily cause confusion to the operation personnel and affect the normal judgment of the operation personnel.

[0004] 2. The feedback timeliness of instruction execution is poor. Since the existing mechanism only reports to the integrated dispatching that the state is executed as long as one partition is successfully executed, the remaining partitions may not be executed or are being executed. At this time, the state is directly reported as executed, and the actual state feedback is not accurate.

[0005] 3. The working state of the broadcast device cannot be accurately obtained. The broadcast instruction task is finally executed on the partition device terminal. Since the state message of the existing feedback mechanism cannot be specific to each partition, it is impossible to accurately know whether the current partition device is working normally, and the self-checking ability of the system device working state is poor. SUMMARY

[0006] The embodiments of the present application provide a broadcast system control method, device, equipment and storage medium to solve the problems of inaccurate feedback result of instruction execution, poor feedback timeliness and inability to accurately obtain the working state of the broadcast device in the prior art.

[0009] According to the partition set, polling check is performed on the database, and the check data is stored in a partition state set;

[0010] The execution result of the broadcast partition is obtained by converting the data in the partition state set and is displayed.

[0011] The second aspect of the present application provides a broadcast system control device, characterized in that the broadcast system control device comprises:

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0024] A broadcast system control method provided by the embodiments of the present application, as shown in Figure 1 The broadcast system control method comprises the following steps.

[0025] Step S101. Obtain a broadcast partition corresponding to a broadcast instruction, send the broadcast instruction, store the broadcast partition in a partition set, and trigger a feedback data check in a database.

[0026] Among them, the broadcast partition that needs to be broadcast is obtained, and the broadcast partition affected by the current instruction is stored in the partition set. The partition set is set to store the broadcast partition affected by the current instruction, so as to facilitate the data check module to process and reduce the redundancy of full partition check. When the broadcast is played in the broadcast partition, the state feedback point corresponding to each broadcast partition is received and stored in the database, and the feedback data check in the database is triggered.

[0027] Among them, the step of storing the broadcast partition in the partition set in step S101 further comprises:

[0028] Receiving the state feedback message of each broadcast partition and storing in the corresponding state feedback point of each broadcast partition in the database.

[0029] Wherein, in the broadcast interface service increases the broadcast partition group, while increasing the corresponding state feedback point of each broadcast partition in the database, the TCP / UDP format state feedback message reported by the broadcast interface service is stored in the corresponding state feedback point of each broadcast partition after parsing according to the specified format.

[0030] Wherein, the trigger feedback data verification in step S101 comprises:

[0031] Start checking the feedback data and start timing.

[0032] Wherein, the verification timeout time is set when starting to check the feedback data, and the verification is stopped when the verification timeout time is reached.

[0033] Step S102. According to the partition set, the database is polled and verified, and the verification data is stored in the partition state set.

[0034] Wherein, step S102 comprises:

[0035] The state feedback point corresponding to the broadcast partition in the database is periodically polled and verified, and the verification result is stored in the partition state set when the verification timeout time is reached.

[0036] Wherein, the partition state set is a cache area, which is mainly set for the storage and state transition of the actual result after data verification. Within the set time range, the execution state of the broadcast partition is periodically obtained from the database according to the partition set; after timeout, the partition state set is updated to record the final result of this verification.

[0037] Since the actual execution of each broadcast partition lags behind the instruction sending time, therefore, reasonable setting of data verification timeout time can take into account timeliness and accuracy, and achieve the best effect. Through test, the timeout time is defined as 10s, which is more reasonable.

[0038] Step S103. The data in the partition state set is converted to obtain the execution result of the broadcast partition and displayed.

[0039] Wherein, step S103 comprises:

[0040] According to the preset broadcast state set, the value state of the data in the partition state set is converted to obtain the final state string of the broadcast partition, and displayed through HMI.

[0041] Among them, HMI (Human Machine Interface), MVB bus (Multifunction Vehicle Bus), and RIOM (Remote Input Output Module) of each carriage. Among them, HMI is set in the front carriage of the train, and RIOM and HMI are both connected to the MVB bus.

[0042] In actual applications, HMIs are installed in the leading cars at both ends of the train. The driver can select the currently working HMI according to the direction of the train. RIOM is connected to the control devices in this car through the IO interface to collect control parameter information of the control devices in this car and send it to the HMI. In actual applications, each control device can correspond to multiple control parameters, and each control parameter corresponds to an IO interface. RIOM can obtain each control parameter through the IO interface corresponding to the control parameter, perform value-state conversion on the data in the partition status set to obtain the final status string of the broadcast partition, and display it through the HMI.

[0043] An embodiment of the present application provides a broadcast system control method that obtains the broadcast partition corresponding to a broadcast instruction, sends the broadcast instruction and stores the broadcast partition in a partition set, simultaneously triggers verification of feedback data in a database, performs polling verification on the database according to the partition set, stores the verification data in a partition status set, converts the data in the partition status set, obtains the execution result of the broadcast partition, and displays it. The present application can provide specific feedback on the actual execution status of the broadcast partition, improves the accuracy of the broadcast partition feedback, avoids feedback blind spots, and achieves one broadcast partition corresponding to one feedback, making it easier for users to understand the partition of the actual device failure, facilitating problem troubleshooting and equipment maintenance.

[0044] The present application is described below through a specific example, and its structural diagram is as follows: Figure 2 As shown, the broadcast interface service includes multiple partitions, and the integrated scheduling system includes a database, a business processing module, and an HMI. The flow chart is as follows Figure 3 As shown, the specific process of this new broadcast feedback mechanism is as follows:

[0045] After selecting the corresponding partition through the integrated scheduling system broadcast module interface, the broadcast instruction is issued.

[0046] When a broadcast instruction is issued, the broadcast partition affected by this instruction is stored in the partition set, a broadcast partition group is added to the broadcast interface service, and status feedback points of each corresponding broadcast partition are added to the database. The status feedback message in TCP / UDP format reported by the broadcast interface service is parsed according to the established format and stored in the status feedback point corresponding to each broadcast partition.

[0047] When the broadcast instruction is issued, the data checking module is triggered to perform polling checking.

[0048] If the timeout is not reached, periodic checking is performed; according to the results in the partition set, only the partition affected by the current instruction is polled, so as to avoid the complexity of checking all the partitions each time.

[0049] If the defined checking timeout time limit of 10 seconds is reached, the results are recorded to the partition state set.

[0050] According to the broadcast state set defined in advance and the final results in the partition state set, the value / state conversion final state string is realized and displayed on the HMI.

[0051] Another embodiment of the present application provides a broadcast system control device, as shown in the accompanying drawings, the broadcast system control device comprises: Figure 4 A broadcast instruction control module 21 is configured to obtain broadcast partitions corresponding to a broadcast instruction, send the broadcast instruction and store the broadcast partitions in a partition set;

[0052] A service processing module 22 is configured to trigger checking of feedback data in a database, perform polling checking of the database according to the partition set, store the checking data in a partition state set, and display the execution results of the broadcast partitions after conversion of the data in the partition state set.

[0053] Further, the broadcast instruction control module 21 is further configured to:

[0054] Receive state feedback messages of each broadcast partition and store the state feedback messages in state feedback points corresponding to each broadcast partition in the database.

[0055] Further, the broadcast instruction control module 21 is configured to:

[0056] Start checking the feedback data and start timing, periodically poll the state feedback points in the database corresponding to the broadcast partitions in the partition set, and store the checking results in the partition state set when the timeout time is reached.
