Abstract

The invention relates to synchronous bus communication and discloses a synchronous communication network terminal address searching method. The method comprises the concrete steps that: a synchronous communication network system is built, wherein the synchronous communication network system comprises a communication host machine and a communication terminal, and the communication host machine and the communication terminal are connected through a synchronous communication bus; the communication host machine sends broadcast commands, the communication terminal carries out self address conversion and then sends the conversion codes to the communication host machine, the communication host machine receives the overlapping of all communication terminal conversion codes, the addresses of all communication terminals are obtained after the analysis, in addition, the addresses are verified with the communication terminals one by one, when one address is the same as the communication terminal address, the address is stored as the communication terminal address, and otherwise, the address is abandoned. After the adoption of the searching scheme provided by the invention, the communication host machine can fast search all equipment in the network no matter how big the communication terminal equipment address is, and the system can enter the normal operation state as fast as possible.

Example Embodiment

[0023] Specific embodiment 1: If there is only one communication terminal device on the synchronous communication network, the address of the device is 10000001 (0x989681 in hexadecimal). First, the communication host sends a broadcast command. After receiving the command, the communication terminal calculates its own address conversion code as (0x02, 0x00, 0x01, 0x00, 0x02, 0x00, 0x00, 0x40, 0x01, 0x00, 0x00, 0x02), And send the conversion code to the communication bus. The communication host receives the conversion code and restores it to a hexadecimal address of 0x989681, then the communication host sends the address to the communication terminal, and the communication terminal responds to the address, then the communication host records the address of the communication terminal. The entire communication search process only needs to send two communication commands, which is very fast.

Example Embodiment

[0024] Embodiment 2: If there are two communication terminal devices on the synchronous communication network, the addresses of the two communication terminal devices are 10000001 (0x989681 in hexadecimal) and 10000002 (0x989682 in hexadecimal). First, the communication host sends a broadcast command. After receiving the command, the two communication terminals calculate their address conversion codes as (0x02, 0x00, 0x01, 0x00, 0x02, 0x00, 0x00, 0x40, 0x01, 0x00, 0x00, 0x02 ) and (0x02, 0x00, 0x01, 0x00, 0x02, 0x00, 0x00, 0x40, 0x01, 0x00, 0x00, 0x04), they send their own address conversion codes to the communication bus at the same time, and the communication host receives the two communications The superposition of terminal address conversion codes is (0x02, 0x00, 0x01, 0x00, 0x02, 0x00, 0x00, 0x40, 0x01, 0x00, 0x00, 0x06), and then parses and restores two communication terminal device addresses, which are 0x989681 and 0x989682 respectively . Then the communication host sends two addresses to the communication terminal equipment respectively, and the communication terminal equipment responds accordingly. During the entire communication search process, only 3 communication commands need to be sent.
[0025] After building a communication network system, the communication host cannot know what communication terminal equipment is connected to the entire communication network. At present, the search efficiency of the two common methods is very low, but all communication terminal devices in the communication network can be quickly searched out by adopting the method of the present invention.
[0026] We use 3 bytes to represent the communication address, that is, the address range is 0x000001-0XFFFFFF. Let's take 1000 communication terminals as an example, and these 1000 communication terminals are serial numbers. The communication host does not know the address information of these 1,000 communication terminals (including the start number and end number, and information such as whether the numbers are consecutive) before searching.
[0027] 1. The debugger enters the serial numbers of all communication terminal devices in the network in the communication host, and then confirms the communication address with the communication terminal one by one according to the address entered by the debugger. This method mainly costs the debugging personnel to record the addresses of all 1,000 communication terminals and the time overhead for inputting the communication terminal addresses. The specific efficiency depends on the efficiency of the debugging personnel.
[0028] 2. The communication host searches according to the default communication address range, where the default address range is 0x000001-0xFFFFFF. That is, the communication host needs to send 16777215 (that is, 0xFFFFFF) communication addresses to inquire and confirm with the communication terminal. If each inquiry time is 10ms, it will take a total of 167772 seconds, about 46.6 hours.
[0029] 3. The communication host detects one by one according to a certain combination. Since these combinations are the default of the communication host, basically all address ranges need to be traversed, so the time is very long. This depends on the selected combination mode. .
[0030]4. If the method among the present invention is used, the communication host sends the broadcast command for the first time, and the communication terminal responds to the communication host with all address conversion codes simultaneously, because the addresses of the communication terminals are consecutive numbers. Therefore, the communication host only needs to send the broadcast address once and address confirmation 1000 times, that is, it needs to send 10001 times, and each inquiry time is 10ms, and it takes a total of 10 seconds to complete the search.
