Description

Technical Field

[0001] The present invention relates to the field of industrial Internet of Things communications, and in particular to a method and a terminal for implementing dynamic configuration based on the Modbus protocol. Background Art

[0002] Modbus protocol is a universal communication protocol that has been widely used in today's industrial control field. With the rise of Internet of Things technology, the demand for data acquisition functions is getting higher and higher. How to adapt to the ever-changing data needs and respond to the remote maintenance needs of industrial and commercial systems has become an increasingly important topic. At present, most industrial equipment data acquisition uses Modbus protocol to transmit data with acquisition equipment. There are many existing industrial equipment models. Different models of the same manufacturer may use different data addresses and command addresses. The data addresses and command addresses of products from different manufacturers are more different.

[0003] Therefore, due to these differences, the following questions arise:

[0004] 1. The compatibility of data acquisition equipment with industrial equipment is relatively poor. At present, data acquisition equipment encodes the required data address and command address into the firmware of the acquisition equipment. Each industrial equipment has different data address and command address, which leads to low versatility of data acquisition equipment and troublesome production and maintenance.

[0005] 2. Data protocol upgrades and maintenance are difficult. After industrial equipment upgrades its firmware, the data addresses and command addresses in some of the original data protocols may change and no longer apply. Therefore, the data acquisition equipment needs to be upgraded and updated synchronously. Since the data addresses and command addresses are encoded in the data acquisition equipment firmware, the only option is to recycle the data acquisition equipment or go to the site to update the equipment one by one, which is cumbersome and increases maintenance costs. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a method and a terminal for realizing dynamic configuration based on Modbus protocol, so as to overcome the defects and shortcomings in the prior art and solve the problem of poor compatibility of the existing data acquisition center with industrial equipment.

[0011] S3. Update the Modbus protocol of the corresponding industrial equipment stored in the acquisition device according to the changed configuration information issued by the data acquisition center, and perform data acquisition on the industrial equipment based on the updated Modbus protocol.

[0012] In order to solve the above technical problems, another technical solution adopted by the present invention is:

[0016] S3. Update the Modbus protocol of the corresponding industrial equipment stored in the acquisition device according to the changed configuration information issued by the data acquisition center, and perform data acquisition on the industrial equipment based on the updated Modbus protocol.

[0017] The beneficial effects of the present invention are as follows: a dynamic configuration implementation method and terminal based on the Modbus protocol of the present invention stores the Modbus protocol configuration of the equipment in the data acquisition center, and when the Modbus protocol of the industrial equipment is changed, the Modbus configuration information in the data acquisition center is changed accordingly, and the configuration information is sent to the acquisition equipment to complete the update of the Modbus protocol stored on the acquisition equipment, so that when the industrial equipment protocol is changed, there is no need to recycle the acquisition equipment and update the firmware of the acquisition equipment one by one, thereby overcoming the defect of poor compatibility of the existing data acquisition center with industrial equipment; at the same time, in the case of the same equipment and the same protocol, only the configuration needs to be copied for reuse without updating the firmware of the acquisition equipment, and at the same time, the operation is simple and easy to use, which greatly improves the versatility and flexibility of the data acquisition module, greatly reduces the maintenance time and workload, and reduces the operating cost.
