For a die-casting workshop, configuring such a system for each die-casting machine results in repeated investment in the system master station and software, without obvious value generated. Moreover, the temperature measurement data can only be viewed on the master station beside the die-casting machine, which is not conducive to the on-site process and quality personnel to view and analyze the data. The computer in the master station is placed in the workshop site with a harsh environment, which also has a certain impact on its service life. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0024] For a more intuitive and complete understanding of the technical solution of the present invention, the non-limiting feature description is as follows in conjunction with the drawings of the present invention:

[0025] As Figure 1 — Figure 4 shown, the on-line temperature measurement system for multiple die-casting molds based on distributed cameras consists of a main station 1, multiple sub-stations 2 and multiple operation terminals 3;

[0026] The master station 1 is connected to the slave station 2 via the network, and it can obtain the infrared thermal images and real-time video streams sent by the slave station 2 in real time, calculate the temperature characteristic parameters (such as the highest temperature, the lowest temperature, the average temperature, etc.) of the key areas of the die-casting mold, and determine whether the temperature is normal;

[0027] Each slave station 2 includes an electric control cabinet 21 and multiple infrared camera modules 22;

[0028] The operation terminal 3 is connected to the master station 1 via the network;

[0029] The master station 1 summarizes, processes and stores the infrared temperature measurement data of multiple die-casting molds.

[0030] The master station 1 is a computer, which has a data processing module 11 and a data display module 12.

[0031] The data processing module 11 includes a data receiving unit 111, a data processing unit 112, a data storage module 113, a data interface 114 and a system setting module. The temperature measurement data is saved to a non-volatile storage medium through the data storage module 113. The data receiving unit 111 is connected to the slave station 2 via the network, and the data interface 114 is connected to the operation terminal 3 via the network; The data display module 12 includes a human-machine interface 121 and a data interface 122. The data interface 122 is used to connect to the data interface 114. The data interface 114 supports multiple protocols, which can be called by the data display module 12 and can also be called by the software in the operation terminal 3.

[0032] The data display module 12 of the master station 1 can obtain relevant data from the data interface 122 and display it on the human-machine interface 121 to interact with the user.

[0033] The master station 1 also has a system configuration module (not shown in the figure), which can configure the relevant parameters of the whole system and manage the system users.

[0034] Each slave station 2 corresponds to a die-casting machine. The infrared camera module 22 measures the temperature of the die-casting mold and sends the data to the master station 1. The electric control cabinet 21 contains modules such as power supply processing, air source processing, and PLC. The number of infrared camera modules 22 is determined by the project requirements and can be flexibly configured. Each infrared camera module 22 mainly includes components such as an infrared camera module, a protection cover plate, and a dust removal air curtain. The electric control cabinet 21 and the infrared camera module 22 are both connected to the master station 1 via the wired or wireless network on the workshop site. The slave station 2 establishes a connection with the die-casting machine control system, receives die-casting machine-related signals, and controls the infrared camera module 22 to measure the temperature. During a die-casting production cycle, there may be several temperature measurement moments. Each time the temperature is measured, the infrared camera module 22 sends the data to the master station 1 for processing.

[0035] The operation terminal 3 is a desktop computer, a laptop computer, a mobile phone, or a tablet. The operation terminal 3 is a broad concept. In theory, any hardware with a display screen and a human-computer interaction method, and installed with the interactive software of this system, can be considered as the operation terminal 3. As a supplement to the main station 1, the operation terminal 3 can be deployed in multiple locations, facilitating the simultaneous use of system functions in multiple user and multiple usage scenarios. The system supports flexible configuration of the number of operation terminals 3, and each operation terminal 3 is connected to the main station 1 through a wired or wireless network.

[0036] The present invention can reduce hardware and software costs; in the case of network coverage, users can view and analyze die temperature data at any location; the interactive software can be flexibly deployed on various operation terminals 3, making full use of existing hardware resources and reducing terminal hardware investment; the system main station 1 can be placed in a better environment to extend the lifespan of the main station 1.

[0037] Of course, the above are only the preferred embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any simple modifications and equivalent structural changes made by using the content of the specification and drawings of the present invention should be equally included in the patent protection scope of the present invention.
