Application of IoT Modules: Remote Monitoring via Mobile APPPLC Data Technical Solutions

Applications of IoT: Extensive, covering various fields such as smart transportation, environmental protection, government work, public safety, home security, smart firefighting, industrial monitoring, environmental monitoring, street lighting control, landscape lighting control, building lighting control, square lighting control, elderly care, personal health, flower cultivation, water system monitoring, food traceability, enemy reconnaissance, and intelligence gathering.

The IoT Module’s Industrial APP: It carries industrial knowledge and experience, meeting specific needs of industrial application software. It is an important outcome of the softwareization of industrial technology, promoting the modeling, modularization, softwareization, and standardization of industrial knowledge and experience, greatly enhancing the application and reuse of knowledge. It can be said that industrial APPs are defining a new way of production and management, even defining the ecosystem of products.

Industry 4.0: In this data-driven era, industrial information or product data is the greatest wealth of enterprises. Technological innovation cannot solely rely on customer satisfaction; it must also be informed by data feedback, such as whether programs run smoothly and the impact of application scenarios on equipment. End users’ demand for “Industry 4.0” is becoming increasingly urgent, requiring industrial equipment manufacturers to consider how to seamlessly integrate their equipment into “Industry 4.0”.

Practical Case of the IoT Module: Given the high development costs of industrial APPs and the lack of technical personnel, our company has launched the GRM552Y-CHE IoT module with WEB GUI-based APP application technology. You do not need to have a background in C++ or Java; you only need to know simple touchscreen applications or PLC applications to easily create beautiful APP process flow diagrams, GIF animations, and background images.

The entire solution includes sensors, contactors, variable frequency motors, etc. The equipment layer includes PLC monitoring systems, web and mobile terminals.

2. Introduction to the Industrial IoT Module

Smart Remote IoT Module GRM530 remote control terminal. GRM530 is a smart remote IoT module specifically designed for wireless communication for PLC remote monitoring and maintenance. With just one module, it enables remote downloading of touchscreen applications, remote debugging of PLCs, uploading and downloading ladder diagrams, remote monitoring of configuration software, SMS alarm notifications, and monitoring via computer web and mobile APP (current data and historical data, historical alarms). The GRM530 is the first in the industry to adopt a combination of 4G, SMS, and voice communication methods, completely solving the instability issues of traditional wireless modules, and through non-transparent transmission methods, it achieves multi-packet concurrent collection, intelligent data compression, and other advanced algorithms, greatly improving system response speed and reducing traffic costs by over 50%. The GRM530 also supports wired network or WIFI access without the need for a fixed IP or bound domain name.

The smart remote IoT module is the optimal solution for wireless communication.

1.1 The screen development is simple and aesthetically pleasing, as shown below, creating a flowchart for mobile and web monitoring (the software includes various libraries and allows adding background images, supporting JPG, PNG, etc.).

6. The smart remote IoT module supports WeChat push fault alarm functions, as well as SMS alarms.

1.1 As shown below, create a new SMS alarm function in the GRM530. When the first press machine overheats, an alarm SMS will be sent to the mobile phone.

1.2 As shown below, after following the WeChat account, an alert will be sent to the mobile phone, ensuring that customers do not miss equipment fault alarms.

7. Summary of the IoT Module.

The mobile industrial APP application, based on its high convenience, strong interactivity, precision, innovation, low cost, and strong user stickiness, enables manufacturing enterprises to shift from centralized management to distributed management, from a passive single-work mode to an interactive duplex work mode, from complex network wiring to plug-and-play wireless deployment, and from broadcast notifications to precise push notifications, thereby creating higher economic value for enterprises.
