[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1 - Figure 4 The STM32-based mold quality monitoring system shown includes a transmitter 1, a transmission control unit, and a receiver 2. One side of the transmitter 1 integrates a probe detection module 101 and a transmission communication unit. The probe detection module 101 is used for contact detection, and the transmission communication unit is used for transmitting detection signals. The transmission control unit is integrated on the other side of the transmitter 1. The transmission control unit is used for detection signal processing and detection signal transmission control. The receiver 2 is wirelessly connected to the transmitter 1. The receiver 2 integrates a receiving communication unit and a receiving control unit. The receiving control unit is used for communication control of the receiver 2.

[0027] The transmission control unit includes a transmitter controller 102. The receiver of the transmitter controller 102 is electrically connected to the transmitter of the probe detection module 101. The output of the transmitter controller 102 is electrically connected to the receiver of the wireless communication transmission module 103. A transmitter power supply module 104 is also integrated on one side of the transmitter 1. The output of the transmitter power supply module 104 is electrically connected to the power input of the probe detection module 101, the transmitter controller 102 and the wireless communication transmission module 103.

[0028] It should be noted that the reference Figure 5 - Figure 8 As shown, the transmitter controller 102 adopts a transmitter control circuit, the probe detection module 101 adopts a probe detection circuit, the wireless communication transmission module 103 adopts a wireless communication transmission circuit, and the transmitter power supply module 104 adopts a transmitter power supply circuit. Among them, the transmitter controller 102 adopts an STM32L432KCU6 controller. The probe detection module 101 sends the level signal to the transmitter controller 102 through the GPIO pin. The probe detection module 101 determines whether the ejector pin is in contact with the object by detecting the high and low levels of the signal, thereby performing quality monitoring of the mold. The transmitter controller 102 sends the data to the 433MHz wireless communication transmission module 103 through the GPIO pin. The transmitter power supply module 104 uses two ER14250 lithium batteries connected in series for power supply, and uses an LDO to step down the voltage to 3.3V to power the transmitter 1.

[0029] The specific transmitting communication unit includes a wireless communication transmitting module 103, which is electrically connected to the transmitting control unit. The receiving communication unit includes a wireless communication receiving module 202, which is integrated on one side of the receiver 2. The wireless communication transmitting module 103 and the wireless communication receiving module 202 are wirelessly connected, and the wireless communication transmitting module 103 and the wireless communication receiving module 202 are used for data transmission via 433MHz wireless communication.

[0030] Furthermore, the receiving communication unit also includes a receiving external communication module 203, which is used to connect to external devices for data transmission. The receiver 2 also integrates a receiving controller 201 and a receiving power supply module 204. The input terminal of the receiving controller 201 is electrically connected to the output terminal of the wireless communication receiving module 202, and the output terminal of the receiving controller 201 is electrically connected to the input terminal of the receiving external communication module 203. The output terminal of the receiving power supply module 204 is electrically connected to the power supply terminals of the receiving controller 201, the wireless communication receiving module 202, and the receiving external communication module 203.

[0031] It should be noted that the reference Figure 9 - Figure 12As shown, the receiver controller 201 employs a receiver control circuit, the wireless communication receiver module 202 employs a wireless communication receiver circuit, the receiver external communication module 203 employs a receiver external communication circuit, and the receiver power supply module 204 employs a receiver power supply circuit. The receiver controller 201 uses an STM32F103C8T6 chip. The wireless communication receiver module 202 is a 433MHz wireless communication receiver circuit, which transmits data to the wireless communication transmitter module 103 via 433MHz wireless communication. The 433MHz wireless communication receiver circuit transmits the received data to the receiver controller 201 via GPIO pins. The receiver external communication module 203 communicates with external devices via serial port, RS485, and GPIO pins. The receiver power supply module 204 uses an externally input 12V DC power supply, which is converted from 5V to 3.3V via an LDDO converter to power the receiver 2.

[0032] The operating principle of this system is as follows: Transmitter 1 uses STM32L432KCU6 as the main controller, which can achieve low power consumption and extend the battery life of the transmitter. Detection is triggered by the probe touching an object. It uses LT4455 chip to communicate with the receiver at 433MHz. The 433MHz wireless communication with the receiver can achieve medium and long distance transmission, strong penetration, low power consumption, and can realize multiple transmitters 1 corresponding to one receiver 2. Receiver 2 uses an STM32F103C8T6 as the main controller and an LR690L chip for 433 communication with the transmitter. It also reserves serial port, RS485, and GPIO for external communication.

[0033] After the probe of transmitter 1 contacts the mold, the high-level signal output to transmitter 1 is pulled low by ground and sent to transmitter 1 through GPIO. Then, the information is transmitted to the 433MHz wireless communication transmitting section of receiver 2 through the 433MHz wireless communication receiving section of receiver 2. The information is then sent to the main controller of receiver 2 through GPIO for data processing.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
