Description

Technical Field

[0001] This invention belongs to the field of transportation equipment technology, specifically relating to a broadcast ID configuration method for a communication-based countdown. Background Technology

[0002] The current method for implementing traffic light countdowns is to install first and then debug. Installers first install the countdown timers and traffic signals for all four directions at the intersection, connecting the wiring and ensuring they are powered on. Then, debugging personnel disconnect the countdown timers from the other intersections, leaving only the countdown timer for the direction requiring debugging connected. Using an ID debugger via RS-485 or other communication methods, they communicate with the countdown timer, assigning it a unique ID. Then, they disconnect the wire of the assigned countdown timer and connect it to the next countdown timer requiring debugging, repeating the same method to set the IDs for the countdown timers in other directions. Once all countdown timers have their IDs set, they reconnect all the countdown timer wires.

[0003] The existing ID setting method is too cumbersome and time-consuming. When debugging a countdown, it is necessary to disconnect the wires of other countdowns and set them one by one using RS-485 or other communication methods. Since the equipment has been installed, it may be necessary to use a high-lift vehicle or other lifting equipment to raise people to work during the debugging process, which is costly and inconvenient. Summary of the Invention

[0004] The technical problem solved by this invention is the cumbersome and time-consuming setup of countdown IDs and the high debugging costs.

[0005] Technical Solution: To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A broadcast ID configuration method for a communication-based countdown includes the following steps:

[0007] S1: Assign a unique SN serial number to the countdown motherboard;

[0008] S2: The host computer software reads the SN serial numbers of the countdown motherboards installed at each intersection and sorts them automatically;

[0009] S3: The host computer software uses broadcast communication to send the serial number to the countdown motherboard and display it;

[0010] S4: Observe the serial number displayed on the countdown motherboards in each direction of the intersection, and manually assign IDs to the countdown motherboards in each direction on the host computer software;

[0011] S5: After the ID allocation is completed, the set ID is sent to the countdown motherboard of each intersection. After receiving its own ID, the countdown motherboard of each intersection turns off the previously displayed serial number. At this time, the ID setting of the countdown motherboard of each intersection is completed.

[0012] Preferably, in step S1, during production testing, the host computer software assigns a unique SN serial number to the countdown motherboard via RS-485 communication, and each countdown motherboard saves these unique SN serial numbers to its own MCU's EEPROM.

[0013] Preferably, in step s2, after the countdown motherboard is installed and wired at the intersection, the host computer software reads the SN serial number of the countdown motherboard installed at each intersection and automatically sorts the SN serial numbers according to the order in which they are read.

[0014] As a preferred option, in step S4, the first step is to observe the countdown display sequence number for each direction at the intersection, and then manually assign IDs to the countdowns for each direction on the host computer software according to the fixed direction ID of the traffic signal or user habits.

[0015] As a preferred option, before configuring the ID, connect the RS-485 communication cable of the countdown motherboard to a 485 to USB converter. Connect the 485 to USB converter to a computer and you can use the host computer software for debugging. The countdown motherboards at the four intersections can be debugged simultaneously.

[0016] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0017] The broadcast ID configuration method for the communication countdown of the present invention does not require disconnecting other connection lines. Simply connect the RS-485 communication line of the countdown to the 485 to USB converter, and then connect the 485 to USB converter to a computer to use the host computer software for debugging. The wiring is convenient, and the countdown at four intersections can be debugged simultaneously and quickly. The setup process does not require the use of high-lift vehicles or other lifting equipment, saving debugging costs.

[0018] When setting the ID in this invention, the countdown does not require disconnecting other connection lines, reducing the workload of debugging; the use of a 485 to USB converter simplifies the debugging tools; the debugging operation using the host computer software is simple and clear, with well-defined steps; the countdown of four intersections can be debugged simultaneously through the host computer, resulting in shorter debugging time, saving time and improving debugging efficiency.

[0026] The present invention will be further illustrated below with reference to specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0027] Before configuring the ID, connect the hardware. Connect the RS-485 communication cable of the countdown motherboard to the 485 to USB converter, and then connect the 485 to USB converter to the PC to use the host computer software.

[0028] The broadcast ID configuration method for a communicative countdown in this application includes the following steps:

[0029] S1: Assign a unique serial number (SN) to the countdown motherboard.

[0030] During production testing, the countdown motherboard is assigned a unique serial number (SN) by the host computer software via RS-485 communication, such as... Figure 1 As shown, the first motherboard is assigned CD22000001, the second motherboard is assigned CD22000002, the third motherboard is assigned CD22000003, and the fourth motherboard is assigned CD22000004. Each countdown motherboard saves these unique serial numbers to the EEPROM of its respective countdown motherboard's MCU.

[0031] The prerequisite for implementing this invention is to have a unique serial number (SN), or identification number, for identification during broadcast communication; this unique SN can be set by hardware circuitry, such as by using a DIP switch, in addition to the methods described above.

[0032] S2: The host computer software reads the serial numbers of the countdown motherboards installed at each intersection and automatically sorts them.

[0033] Install a countdown timer motherboard at the intersection, such as Figure 2As shown, after the countdown motherboard is installed and wired at the intersection, the debugging personnel use the host computer software to read the SN serial numbers of the countdown devices installed at each intersection. The host computer software automatically sorts the SN serial numbers according to the order in which they are read, such as... Figure 3 As shown, for example: the first SN serial number read is CD22000003, row 01; the second SN serial number read is CD22000002, row 02; the third SN serial number read is CD22000004, row 03; and the fourth SN serial number read is CD22000001, row 04.

[0034] S3: Use broadcast communication on the host computer software to send the serial number to the countdown motherboard and display it.

[0035] like Figure 4 As shown, the debugging personnel then send the sequence number arranged by the SN serial number to the countdown motherboard at each intersection via broadcast communication, and send instructions to the countdown motherboard at each intersection to display the received sequence number.

[0036] S4: Observe the serial numbers displayed on the countdown mainboards for each direction at each intersection, and manually assign IDs to the countdown mainboards for each direction on the host computer software according to the fixed direction IDs of the traffic signals or user habits.

[0037] The debugging personnel observed the countdown display numbers for each intersection direction, such as... Figure 4 As shown, for example, the countdown timer for the east direction displays 04, the countdown timer for the south direction displays 01, the countdown timer for the west direction displays 03, and the countdown timer for the north direction displays 02. Then, the debugging personnel manually assign IDs to the countdown timers for each direction in the host computer software according to the fixed direction IDs of the signal lights or user habits. This example uses the customary setting of east, south, west, and north directions, such as... Figure 5 As shown, for example: countdown 04 in the east direction is assigned to 001, countdown 01 in the south direction is assigned to 002, countdown 03 in the west direction is assigned to 003, and countdown 02 in the north direction is assigned to 004.

[0038] S5: After ID allocation is complete, the configured IDs are sent to the countdown mainboards at each intersection. Upon receiving their own IDs, each intersection's countdown mainboard turns off the previously displayed sequence number.

[0039] After the allocation is completed, the debugging personnel will use the broadcast communication method on the host computer software to send the configured IDs to the countdown motherboards at each intersection, such as... Figure 6 As shown. After receiving its own ID, the countdown motherboard at each intersection turns off the previously displayed sequence number. At this point, the ID setting for each countdown motherboard at each intersection is complete.

[0040] The advantages of this invention are that the countdown motherboard does not need to disconnect other connection lines. Simply connect the RS-485 communication line of the countdown motherboard to the 485 to USB converter, and connect the 485 to USB converter to the computer to use the host computer software for debugging. The wiring is convenient, and the countdown motherboards at four intersections can be debugged simultaneously and quickly. No high-rise vehicle or other lifting equipment is needed during the setup process, saving debugging costs.

[0041] When setting the ID, the countdown does not require disconnecting other connection cables, reducing the workload of debugging; using a 485 to USB converter, the debugging tools are simple; using the host computer software for debugging is simple and clear, with well-defined steps; the countdown of four intersections can be debugged simultaneously through the host computer, resulting in short debugging time, saving time and improving debugging efficiency.

[0042] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
