[0001] The utility model relates to the technical field of aging cabinets, and more specifically, to an intelligent aging cabinet with temperature monitoring and automatic power-off. Background Art

[0002] So far, existing aging equipment has added a PLC controller, a temperature sensor, a turntable, an L-shaped telescopic rod, and a camera. The camera and the temperature sensor collect information inside the cabinet in real time and transmit it to the PLC controller. After being processed by the intelligent processing chip inside the PLC controller, it is transmitted to the data storage disk for storage, thus realizing data collection.

[0003] Regarding the existing technology, it can be seen that although relatively intelligent aging equipment can realize real-time collection and upload of information. However, when facing problems such as short circuits, too high cabinet temperature, and other potential problems during the aging process of products, it cannot automatically cut off the power, which may cause damage to products and other related equipment, and even lead to the loss of important data.

[0004] Therefore, it is necessary to propose an intelligent aging cabinet with temperature monitoring and automatic power-off to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-7 , an intelligent aging cabinet with temperature monitoring and automatic power-off, including an aging cabinet body 4. A power supply two 26 is arranged in the aging cabinet body 4. The power supply two 26 is used to supply power to the input ends of a power supply one 22 and a current-limiting circuit board 25. An air switch 21 is arranged between the power supply one 22 and the power supply two 26. The current-limiting circuit board 25 is electrically connected to a banana plug 2. An independent switch 12 is arranged between the current-limiting circuit board 25 and the banana plug 2. The power supply one 22 supplies power to a time control switch control panel 9, a temperature sensor 7, a temperature display meter 8, a smoke sensor 6, the power supply end of the current-limiting circuit board 25, and a voltage and ammeter 10. The temperature sensor 7 is communicatively connected to the time control switch control panel 9. The time control switch control panel 9 controls the opening and closing of the air switch 21. The smoke sensor 6 detects the real-time value of the gas concentration in the aging cabinet body 4 and judges whether the real-time value exceeds the range. After exceeding the range, the smoke sensor 6 emits an alarm sound for alarm. The current-limiting circuit board 25 is provided with a chip control circuit, an automatic power-off circuit, and a power supply circuit.

[0028] Specifically, there are multiple energized spaces on the left side of the aging cabinet body 4. Each energized space is equipped with an independent switch 12 and a voltage and current meter 10 for monitoring the input voltage and current of the monitoring current-limiting circuit board 25. The right side of the aging cabinet body 4 is the control side.

[0029] The multiple energized spaces are separated by a support mesh plate. Each energized space is used as a layer. The left-side energized space occupies 3 / 4 of the aging cabinet body 4. The right-side 1 / 4 part is used to install the voltage and current meter 10 and the independent switch 12 for easy real-time monitoring and operation. A temperature display meter 8 is set at a position slightly above the right-side 1 / 4 part to quickly view the current temperature. The time control switch control panel 9 is set at the junction of the first layer and the second layer. After installing the time control switch control panel, a 220V socket 15 is set on the left side of the aging cabinet body 4 to ensure that the aging cabinet body 4 can obtain a stable AC power supply when needed. At the same time, four pairs of red and black banana plugs 2 are installed in the energized space of the aging cabinet body 4 near the cabinet door 11. These banana plugs are designed specifically for 24V DC power supply.

[0030] Specifically, the control side is provided with a temperature display meter 8 for displaying the value of the temperature sensor 7, and the temperature display meter 8 is used to facilitate the staff to view.

[0031] Specifically, a mesh air outlet 14 and an exhaust fan 1 are provided on the aging cabinet body 4 of each energized space to facilitate the heat dissipation of the cabinet body.

[0032] Specifically, multiple groups of banana plugs 2 are provided in the energized space to increase the compatibility of the equipment.

[0033] Specifically, two cabinet doors 11 are symmetrically and rotatably provided on the front side of the aging cabinet body 4 of each energized space. The two cabinet doors 11 are symmetrically arranged and rotatably provided at the port of each energized space.

[0034] The principle of the present utility model is described in five parts:

[0035] 1. Power supply part design: The present utility model uses the mains 220V as the main power supply. At the same time, a 220V socket 15 is adhered to the right side wall of the bottom layer of the aging cabinet body 4, and the wire is led from the bottom of the cabinet to the mains 220V, so as to realize the 220V AC power supply. Further, the 220v mains is converted into 24V DC power through the power supply unit two 26 to realize the 24V DC power supply.

[0036] 2. Protection and display part design: In this utility model, the power supply terminal of the voltage and current meter 10 is connected to the first power supply 22, and the detection terminal of the voltage and current meter 10 is connected to the power supply to be measured on each layer. At this time, as long as a certain layer is powered on, the voltage and current meter 10 on that layer will display the current voltage and current values of that layer. Further, the current threshold is set internally in the current limiting circuit board 25 through programming. At the same time, the user can adjust the current threshold through the button on the current limiting circuit board 25. When the chip control circuit of the current limiting circuit board 25 detects that the value exceeds the threshold, the current limiting circuit board 25 will cut off the output 24V to achieve the automatic power-off function. Further, a smoke sensor is also provided inside the aging cabinet body 4. The smoke sensor is installed on the upper wall of the aging cabinet body 4. After being powered by the first power supply 22, it can detect the gas value. When the threshold is reached, the smoke sensor will emit an alarm sound. In addition, similarly, the temperature display meter 8 is connected to both ends of the temperature sensor 7. As long as the temperature sensor 7 is working, the temperature display meter 8 will display the current temperature value in real time. Once the value monitored by the temperature display meter 8 exceeds the threshold, the time control switch control panel 9 will control the air switch 21 to automatically cut off the power.

[0037] 3. Data acquisition and monitoring part design: In this utility model, the PLC controller 19 and the product module are configured. Data acquisition and storage are enabled in the PLC control software, and then the program is downloaded into the PLC controller 19. When aging, the PLC controller 19 and the product are placed in the intelligent aging cabinet at the same time, powered on, the product and the PLC controller 19 complete the configuration, start running the program, conduct aging and data acquisition, and finally store the data in the PLC controller 19. The operator only needs to view the data on the computer.

[0038] 4. Time control switch control part design: The time parameter setting is controlled by the time control switch control panel 9 of the KG316T model. Buttons are provided on the panel, and the operator can set the current time, the time required for aging, the automatic or manual mode, and the on and off of the main power supply.

[0039] 5. Internal circuit control part design: Please refer to Figures 4 to 7 , the circuit design part of the current limiting circuit board 25 in this utility model includes a chip control circuit, an automatic power-off circuit, and a power supply circuit part. Among them, the power sensor in the power supply circuit detects the input voltage and current. By setting the threshold independently, once the preset threshold is exceeded, the automatic power-off circuit will automatically disconnect the relay in the current limiting circuit board 25, thereby ensuring the safety of the circuit and achieving the automatic power-off function.

[0040] Power supply circuit: The first power supply 22 supplies power to the power supply terminal of the current limiting circuit board 25. The 24V power supply terminal enters the current limiting circuit board 25 and is stepped down by the 78L05 chip to supply power to other components of the current limiting circuit board 25. The input end of the current limiting board is input with 24V voltage from the second power supply 26.

[0041] Chip control circuit: The single-chip microcomputer judges the threshold value of the current set by the user by detecting the presses of the setting button, the increasing button, and the decreasing button on the single-chip microcomputer. The set current threshold value is stored in the memory of the single-chip microcomputer. The single-chip microcomputer compares the threshold value with the input current value to judge whether it exceeds the threshold value. If it exceeds, the single-chip microcomputer sends a cut-off signal, and there is no 24V voltage output at the output end of the current-limiting circuit board 25. Thus, there is no current in the banana plug 2, and there is no current in the device connected to the banana plug 2.

[0042] Automatic power-off circuit: When the set threshold value is exceeded, the single-chip microcomputer sends a cut-off signal to control the relay on the current-limiting circuit board 25 to disconnect. After the relay disconnects, the circuit forms an open circuit and there is no voltage output. When the set threshold value is not exceeded, the single-chip microcomputer sends an on signal to control the suction of the relay. After the relay sucks, a closed circuit is formed and the voltage is normally output at 24V.

[0043] Usage method: Plug in the power supply of the aging cabinet body 4, and then press the switch button on the time control switch control panel 9. The air switch 21 is sucked in, and the smoke sensor 6, the current-limiting circuit board 25, the temperature sensor 7, the temperature display meter 8, and the voltage and ammeter 10 are powered on. Then turn on the independent switch 12, and turn on the independent switch 12 of the layer that needs to be aged.

[0044] If the PLC controller and the product are 220V alternating current, insert the positive and negative poles of the power supply of the PLC controller and the product into the 220V socket strip 15, and then turn on the switch of the 220V socket strip 15;

[0045] If the PLC controller and the product are 24V direct current, connect the PLC controller or the product to the banana plug 2 respectively, where the red is the positive pole and the black is the negative pole. After connecting, close the sealing door and turn on the right independent switch 12;

[0046] If the PLC controller is 220V alternating current and the product is 24V direct current, insert the PLC controller into the 220V socket strip 15, connect the product to the banana plug 2 respectively with red + and black -, and then turn on the switch of the 220V socket strip 15 and the independent switch 12;

[0047] Finally, when the product starts to age, the voltage and ammeter 10 will display the current voltage and current.

[0048] When it is necessary to configure the aging timing time, the operator needs to continuously press the corresponding button four times on the time control switch control panel 9 to start the setting mode. Subsequently, enter the clock setting interface by pressing the clock button, and use the hour adjustment, minute adjustment, and week adjustment buttons to accurately set the current time. After the setting is completed, press the clock button again to save the current time setting. Next, the user needs to click the timing button to enter the timing setting interface, and repeat the above steps to set the required aging time. Finally, press the timing button to save the current timing setting.

[0049] When setting the power-off threshold, the operator needs to press the setting key on the current-limiting circuit board 25 once to enter the protection current setting state. The decimal point of the digital tube starts to flash, indicating that the protection current setting state has been entered. Then, press the increase and decrease keys to modify the protection current. The protection current ranges from 0.1A to 30A. After the current setting is completed, press the setting key twice, and the digital tube stops flashing. The protection current is automatically stored in the single-chip microcomputer EEPROM.

[0050] When the aging cabinet body 4 is working, after the independent switch 12 on each layer is turned on, the 220V power supply first passes through the power supply unit two 26 and is converted into a 24V power supply. The 24V power supply is respectively supplied to the input ends of the power supply unit one 22 and the current-limiting circuit board 25. The current-limiting circuit board 25 corresponding to the energized space on each layer will monitor the magnitude of the voltage and current. When the corresponding monitored value exceeds the set threshold, the current-limiting circuit board 25 will disconnect its own relay, thereby disconnecting the power supply to the banana plug 2. Among them, the power supply unit one 22 will supply power to the time control switch control panel 9, the temperature sensor 7, the temperature display meter 8, the smoke sensor, the input end of the current-limiting circuit board 25, and the voltage and current meter 10. During the operation of the aging cabinet body 4, the temperature sensor 7 will continuously monitor the internal value of the aging cabinet body 4 and display the value on the temperature display meter 8, and at the same time feedback it to the time control switch control panel 9. When the monitored value exceeds the set threshold, at this time, the time control switch control panel 9 controls the air switch 21 to close, disconnecting the power supply to the aging cabinet body 4. At the same time, when the value monitored by the smoke sensor 6 exceeds the range, it will emit an alarm sound by itself.

[0051] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention is subject to the claims. All equivalent structural changes made by using the description and drawings of the present invention should be included in the protection scope of the present invention by the same token.
