[0054] It should be understood that Figure 3 The number of computing devices and alarm devices in the embodiment is merely illustrative. Any number of computing devices and alarm devices may be provided as required.

[0055] Continue to refer Figure 4 , showing a process 400 of some embodiments of the alarm device control method according to the present disclosure.

[0056] The alarm device control method comprises the following steps:

[0057] Step 401: Receive a set of infrared thermal image information in a three-color extrusion die.

[0058] In some embodiments, the execution subject of the alarm device control method (eg Figure 3The computing device 301 shown in the figure can receive a set of infrared thermal image information within a three-color extrusion die. The above-mentioned infrared thermal image information set can be a set of infrared thermal image information. The above-mentioned infrared thermal image information can be related information about the infrared thermal images of the flow channel holes within the three-color extrusion die. The above-mentioned infrared thermal image information can include flow channel hole identification and infrared thermal image. The above-mentioned infrared thermal image can be a temperature distribution image of the flow channel holes within the three-color extrusion die. In practice, the above-mentioned execution entity can receive a set of infrared thermal image information within the three-color extrusion die captured by an associated infrared thermal imager. For example, the above-mentioned execution entity can receive infrared thermal images of two-jet flow channel holes captured by an associated infrared thermal imager for detecting two-jet flow channel holes. The above-mentioned execution entity can also receive infrared thermal images of three-jet flow channel holes captured by an associated infrared thermal imager for detecting three-jet flow channel holes. The flow channel hole identification corresponds to the flow channel hole detected by the infrared thermal imager. Thus, the execution entity can receive a set of infrared thermal image information including the flow channel hole identification and infrared thermal image information of the two-jet flow channel hole, and the flow channel hole identification and infrared thermal image information of the three-jet flow channel hole. The received set of infrared thermal image information can thus provide data support for obtaining a temperature discrimination result.

[0059] Step 402: Input each infrared thermal image included in the infrared thermal image information set into a temperature discrimination model to obtain a temperature discrimination result set.

[0060] In some embodiments, the execution entity may input each infrared thermal image included in the infrared thermal image information set into a temperature discrimination model to obtain a set of temperature discrimination results. The temperature discrimination model may be a neural network model that uses infrared thermal images as input data and outputs temperature discrimination results. For example, the neural network model may be a convolutional neural network model. The temperature discrimination result set may be a set of temperature discrimination results. The temperature discrimination result may be a normal temperature, a first temperature abnormality result, or a second temperature abnormality result. The first temperature abnormality result may indicate that the temperature of a flow channel hole in a three-color extrusion die is below a minimum temperature threshold. The second temperature abnormality result may indicate that the temperature of a flow channel hole in a three-color extrusion die is above a maximum temperature threshold. The specific settings of the minimum and maximum temperature thresholds are not limited. For example, the execution entity may input each infrared thermal image included in the infrared thermal image information set into the temperature discrimination model. When the temperature of a second jet channel hole is below the minimum temperature threshold, the temperature discrimination result obtained using the infrared thermal images corresponding to the second jet channel hole and the temperature discrimination model is the first temperature abnormality result. Therefore, the obtained temperature discrimination result can provide data support for the alarm device to perform alarm operations.

[0061] Step 403: For each temperature discrimination result in the temperature discrimination result set, perform the following steps:

[0062] Step 4031 : In response to determining that the temperature discrimination result is a first temperature abnormality result, controlling the associated alarm device to perform a first alarm operation according to the flow channel hole identifier corresponding to the temperature discrimination result.

[0063] In some embodiments, the execution entity may, in response to determining that the temperature determination result is a first temperature anomaly, control an associated alarm device to perform a first alarm operation based on the runner hole identifier corresponding to the temperature determination result. The alarm device may be a device with an alarm function. The first alarm operation may include the alarm device emitting a first alarm sound and flashing a light corresponding to the runner hole identifier. The first alarm sound may be an alarm sound indicating that the temperature within the mold is too low. The light flashing corresponding to the runner hole identifier may flash a light of the color corresponding to the runner hole identifier. In practice, the execution entity may, in response to determining that the temperature determination result is a first temperature anomaly, control an associated alarm device to perform the first alarm operation based on the runner hole identifier corresponding to the temperature determination result via a wired connection. For example, in response to determining that the temperature determination result for the second fluidic channel hole is a first temperature anomaly, the associated audible and visual alarm may be controlled to emit a "temperature too low" alarm sound and flash a red light. In response to determining that the temperature determination result for the third fluidic channel hole is a first temperature anomaly, the associated audible and visual alarm may be controlled to emit a "temperature too low" alarm sound and flash a blue light. Thus, when the temperature inside the three-color extrusion die is too low, the alarm device can be caused to perform the first alarm operation, so that the operator can be informed of the location and situation of the temperature anomaly in a timely manner.

[0064] Step 4032: In response to determining that the temperature discrimination result is a second temperature abnormality result, the alarm device is controlled to perform a second alarm operation according to the flow channel hole identifier corresponding to the temperature discrimination result.

[0065] In some embodiments, the execution entity may, in response to determining that the temperature determination result is a second temperature anomaly, control the alarm device to perform a second alarm operation based on the runner hole identifier corresponding to the temperature determination result. The second alarm operation may include causing the alarm device to emit a second alarm sound and flash a light corresponding to the runner hole identifier. The second alarm sound is an alarm sound when the temperature within the mold is too high. In practice, the execution entity may, in response to determining that the temperature determination result is a second temperature anomaly, control the alarm device to perform the second alarm operation based on the runner hole identifier corresponding to the temperature determination result. For example, in response to determining that the temperature determination result for the second fluidic channel hole is a second temperature anomaly, the associated sound and light alarm may be controlled to emit a "temperature too high" alarm sound and flash a red light. In response to determining that the temperature determination result for the third fluidic channel hole is a second temperature anomaly, the associated sound and light alarm may be controlled to emit a "temperature too high" alarm sound and flash a blue light. Thus, when the temperature within the three-color extrusion mold is too high, the alarm device may perform the second alarm operation, allowing the operator to promptly notify the location and condition of the temperature anomaly.

[0066] The above-described embodiments of the present disclosure have the following advantageous effects: Through the alarm device control methods of some embodiments of the present disclosure, the temperature within the mold can be monitored, and an alarm can be promptly issued when the temperature within the mold is too high or too low, thereby preventing mold damage. Specifically, mold damage is caused by failure to monitor the temperature within the mold, resulting in failure to issue an alarm when the temperature within the mold is too high or too low. The alarm device control methods of some embodiments of the present disclosure can receive a set of infrared thermal image information within a three-color extrusion mold, wherein the infrared thermal image information in the set includes runner hole identification and infrared thermal images. Thus, the received set of infrared thermal image information can provide data support for obtaining a temperature discrimination result. Each infrared thermal image included in the set of infrared thermal image information is input into a temperature discrimination model to obtain a set of temperature discrimination results, wherein the temperature discrimination results in the set of temperature discrimination results are normal temperature, a first temperature abnormality result, or a second temperature abnormality result. Thus, the obtained set of temperature discrimination results can provide data support for the alarm device to execute an alarm operation. For each temperature discrimination result in the temperature discrimination result set, the following steps are performed: in response to determining that the temperature discrimination result is a first temperature anomaly result, the associated alarm device is controlled to perform a first alarm operation based on the flow channel hole identifier corresponding to the temperature discrimination result. Thus, when the temperature inside the three-color extrusion mold is too low, the alarm device can be caused to perform the first alarm operation so that the operator can promptly know the location and situation of the temperature anomaly. In response to determining that the temperature discrimination result is a second temperature anomaly result, the alarm device is controlled to perform a second alarm operation based on the flow channel hole identifier corresponding to the temperature discrimination result. Thus, when the temperature inside the three-color extrusion mold is too high, the alarm device can be caused to perform a second alarm operation so that the operator can promptly know the location and situation of the temperature anomaly. Furthermore, the temperature inside the mold can be monitored. When the temperature inside the mold is too high or too low, an alarm can be executed in a timely manner, thereby preventing damage to the mold.
