[0002] When the PLC master station and the display terminal slave station communicate, if the communication resources are sufficient and the number of slave stations is small, a one-to-one communication method is usually adopted for the convenience of programming; if the communication resources are insufficient, a polling method is used for data communication.

[0003] In the process of polling communication, the more slave stations there are, the longer it takes to complete a round of polling, which will result in poorer timeliness of the data received by the slave stations. For some data with high timeliness requirements, this communication method cannot meet the timeliness requirements. Summary of the invention

[0023] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings.

[0024] Embodiment 1

[0025] Figure 1 This is a flow chart of the data fusion communication method of the display terminal provided in the first embodiment of the present application, such as Figure 1 As shown, the data fusion communication method for the display terminal provided in this embodiment can be applied to a data fusion communication platform of the display terminal mounted on a device with data processing capability such as a computer, and can be used in conjunction with some application software to achieve a better experience. Specifically, the method may include the following steps:

[0026] Step 101: The master station fuses the data required by each display terminal according to a preset data format to obtain fused data, and sends the fused data to each display terminal.

[0027] In this step, the master station may be a control device such as a PLC, and each display terminal is a slave station of the master station. The slave station may be connected to the communication bus of the master station to achieve communication connection with the master station.

[0028] The master station will merge the data required by each display terminal according to a preset data format. Specifically, the master station can obtain the data required to be sent to each display terminal and the address identification information of the corresponding display terminal.

[0029] For the data required by any display device, the data and the address identifier of the display device are used as the intermediate data body, and the data group identifier is added to the front end of the intermediate data body and the end identifier is added to the back end to obtain the data body corresponding to the display device; the data bodies of all display devices are merged into one piece of data to obtain fused data.

[0030] The data group identifier may be a pre-agreed first identifier character, and the end identifier may be a pre-agreed second identifier character. Figure 4 , Figure 4 A schematic diagram of a data format provided for Example 1 of the present application.

[0031] like Figure 4 As shown in FIG. 1 , a data stream is formed by data bodies of n display terminals. Each data body includes a data group identifier, a device address, a data intermediate body, and an end identifier in sequence. The data intermediate body includes data required by multiple display terminals.

[0032] In addition, when a new display terminal is added, the new display terminal sends an address allocation request to the main station, and the address allocation request includes the device identification code of the display terminal; the main station allocates an address to the new display terminal based on the address allocation request, and merges the device identification code and the allocated address information into an address allocation intermediate data body; the address allocation intermediate data body is used as the data required by the display terminal.

[0033] Adding a new display terminal means adding a display terminal as a new slave to the master station in the master-slave system. In order to simplify the configuration process, this embodiment automatically completes the addition of the slave station with the help of the device identification code of the display terminal. The addition process is mainly to assign an address to the display terminal, so an address allocation request can be sent to the master station.

[0034] In a specific embodiment, the address allocation request may include a slave request identifier, a device identification code, and an end identifier in sequence. Similarly, the slave request identifier may be a pre-determined third identification character. After receiving the address allocation request, the master station allocates a new device address for the device identification code.

[0035] It should be noted that the mapping relationship between the device identification code of each display terminal and the allocated address may be stored in the master station, so that the master station can add the corresponding device address information for each display terminal when generating fusion data.

[0036] Correspondingly, when fusion is performed, if there is an address allocation intermediate data body corresponding to the display terminal performing address allocation, an address allocation identifier is added to the front end of the address allocation intermediate data body and an end identifier is added to the back end to obtain the data body corresponding to the display terminal performing address allocation.

[0037] In a specific example, the aforementioned data body may exist in the data stream, and the data body includes an address allocation identifier, a device identification code, address information, and an end identifier in sequence.

[0038] When receiving the data stream, the slave station obtains the next field content of the data group identifier each time it traverses to an address allocation identifier; determines whether the device identification code in the next field content matches the current display terminal, and if so, extracts the field between the address allocation identifier and the nearest end identifier; and determines the address information in the extracted field as the device address of the current display terminal.

[0039] Based on this process, the newly added display terminal can obtain the device address assigned by the master station.

[0040] Step 102: For any display terminal, traverse each field in the received fused data, and obtain the next field content of each data group identifier when traversing to a data group identifier.

[0041] In this step, the data belonging to the current display terminal is extracted by traversal. This step is performed by any display terminal and the received fused data is traversed field by field.

[0042] Since the field immediately following the data group identifier is used to store the address identifier information, each time a data group identifier is traversed in this step, the next field content needs to be obtained. It should be noted that if an address allocation identifier is traversed, the next field content of the data group identifier also needs to be obtained.

[0043] Step 103: determine whether the address identification information in the next field content is consistent with the current display terminal. If it is consistent, extract the field between the data group identifier and the nearest end identifier.

[0044] In this step, the address information of the current display terminal may be obtained first, and it is determined whether the address identification information in the next field content contains the address information; if so, it is determined to be consistent with the current display terminal; if not, it is determined to be inconsistent.

[0045] It should be noted that, usually, the address information can be a type of characters and formats predetermined between the master station and the slave station, such as using numbers 1, 2, 3, etc. to represent the address. For some routine data that needs to be received, such as data that each display terminal needs to receive, when merging, the address information of multiple display terminals can be added to the device address field. Therefore, for the current display terminal, as long as it contains the address information of the display terminal, it can be determined to be consistent.

[0046] In addition, each time an address allocation identifier is traversed, the next field content of the data group identifier is obtained; it is determined whether the device identification code in the next field content matches the current display terminal. If it matches, the field between the address allocation identifier and the nearest end identifier is extracted; the address information in the extracted field is determined as the device address of the current display terminal.

[0047] That is to say, if the data group identifier is traversed, the consistency of the address information is determined, and if the address allocation identifier is traversed, the consistency of the device identification code is determined.

[0048] In this embodiment, the master station fuses the data required by each display terminal according to a preset data format to obtain fused data, and sends the fused data to each display terminal; for any display terminal, traverse each field in the received fused data, and obtain the next field content of the data group identifier each time a data group identifier is traversed; determine whether the address identifier information in the next field content matches the current display terminal, and if so, extract the field between the data group identifier and the nearest end identifier. Based on this, the data of each display terminal is fused into one piece of data for transmission, and the display terminal extracts the data segment belonging to itself according to the address identifier information, and the communication can be completed without polling, which effectively improves timeliness.
