Description

Technical Field

[0001] The present invention relates to the technical field of PLC module production, in particular to an HPLC upgrade base plate, a dual-mode upgrade system and an upgrade method for PLC module upgrade. Background Art

[0002] Driven by technologies such as big data, artificial intelligence, 5G, and the Internet of Things, PLC controllers are no longer simply digital systems and computing control units in the industrial control industry. PLC module products are mainly composed of five parts: central processing unit CPU, storage unit, basic I / O interface circuit, interface circuit expansion I / O and communication part. PLC module products have been widely used in power grids, automobiles, chemicals, petroleum, and other industrial fields. Among them, the demand for smart Internet of Things devices such as smart grids, IoT smart street lights, smart homes, smart parking, and central air conditioning is also exploding. With the rapid growth in demand for PLC modules, production capabilities such as embedded software implantation are also facing continuous optimization and improvement during the manufacturing process.

[0003] Conventional PLC module software upgrades, since most products are upgraded for the central controller CPU related processing functions, refer to Figure 1 As shown, during the manufacturing process, the module software needs to be connected through the serial port circuit, for example, using Figure 2 The USB serial port conversion chip in the module is used to burn the upgrade software to the built-in memory area of ​​the PC or NB using the serial port communication protocol. For this type of PLC module upgrade method, since the upgrade software burning is only a physical storage process of writing, it is impossible to control and monitor online. After the burning is completed, the performance and function of the product need to be retested on the production line to ensure that it meets the relevant quality standards and arrange the module packaging and shipment.

[0004] However, during the module software burning process, since the relevant serial port adapter chip is needed for data protocol transmission, and it is necessary to purchase test fixtures, upgrade the production line and build a test environment, etc., after the module upgrade is completed, all product performance and function production line links need to be tested, resulting in long production cycle, high loss and high cost. Summary of the invention

[0005] The purpose of the present invention is to provide an HPLC upgrade baseboard and a dual-mode upgrade method for PLC module upgrade, in view of the problem that in the prior art, the module software needs to be burned into the built-in memory area of ​​the module through a serial port circuit and a serial port communication protocol, resulting in the need for production line retesting of the produced modules, which in turn leads to the problems of long production cycle, large loss and high cost.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] An HPLC upgrade baseboard for PLC module upgrade, comprising: a signal interface connector, and a plurality of upgrade modules for installation in the PLC module; the signal interface connector is used for wired connection to an upgrade main control; a plurality of the upgrade modules are connected to the signal interface connector through a circuit layout;

[0008] The upgrade module includes: a module connection port, a signal transmission line, a wireless power supply interface and a signal isolation zone between modules; the module connection port is used to install the PLC module; the wireless power supply interface is used to wirelessly communicate with the upgrade main control; the isolation zone is used to isolate interference signals between modules.

[0009] The HPLC upgrade baseboard for PLC module upgrade described in the present invention is provided with a signal interface connector, and multiple upgrade modules are connected to the signal interface connector, each of the upgrade modules is provided with a module connection port, and the PLC module to be upgraded can be installed on the upgrade module through simple installation, and then the signal interface connector is wired to the upgrade main control, so that multiple upgrade modules can be wired to the control end through the HPLC upgrade baseboard at the same time, and upgraded at the same time, which plays an efficient role in the concurrent data transmission of PLC signals in the data processing process, on the one hand, improving the efficiency of module upgrade; on the other hand, in conjunction with the simultaneous upgrade, each of the upgrade modules is provided with a wireless power supply interface, and the PLC module The groups communicate with the upgrade master control through wireless signals respectively, for example, automatically networking and connecting with the upgrade master control, or the upgrade master control monitors the upgrade status of the PLC module through the wireless power supply interface, and can obtain the signal whether the PLC module has been successfully upgraded. If the upgrade is not completed, it will be installed again-upgraded until the upgrade is successful, and there is no need to perform upgrade retesting to verify whether the upgrade is successful, making the upgrade process of the PLC module more controllable, improving the quality of the PLC module upgrade, and reducing the loss and time cycle cost caused by retesting, thereby improving production efficiency; and by setting an isolation belt, the antenna isolation of the wireless signal communication can be increased, making the signal more stable, improving transmission efficiency, and reducing errors and failure rates.

[0010] A further improvement of the present invention is that the signal isolation zone includes: a signal clearance zone and an inter-module isolation zone; the signal clearance zone is arranged at the periphery of the signal transmission line; and the inter-module isolation zone is arranged at the periphery of the power connection port of the PLC upgrade module.

[0011] As a further improvement of the present invention, by setting a signal clearance area, signal interference between signal transmission lines can be avoided, and the radio frequency signal of the wireless signal antenna can also be avoided from interfering with the data transmission of the signal line, so that the isolation between the wired transmission and wireless communication of the dual-mode upgrade is stronger, further improving the transmission efficiency and reducing the probability of signal transmission interference interruption or error; and, by setting an inter-module isolation area on the periphery of the power connection port of the upgrade module, an inter-module isolation area can be formed between each of the upgrade modules, further reducing the radio frequency wireless signal interference between modules, further increasing the antenna isolation of the wireless signal communication, and making the signal more stable.

On the basis of having the ability of multi-module concurrent upgrade, if the upgrade module spacing is too small, signal interference is likely to occur; if the upgrade module spacing is too large, the arrangement of upgrade modules on the same HPLC upgrade base plate is even smaller, which affects the upgrade efficiency. A further scheme of the present invention sets the number of HPLC upgrade base plates to six to eight with a spacing of 5mm-10mm, which can take into account both upgrade transmission efficiency and anti-interference, optimize the setting of the HPLC upgrade base plate, and further enhance the module upgrade effect and upgrade production efficiency.

[0014] According to a further improvement of the present invention, a first mechanical positioning hole is provided in the middle of a side opposite to the power input port of the HPLC upgrade base plate, and mutually symmetrical second mechanical positioning holes are provided on two sides adjacent to the side with the first mechanical positioning hole.
