[0112] When a host computer is provided, the information from the data acquisition and processing device can be displayed remotely on the host computer, making it more convenient to obtain information.

[0113] Based on the above embodiments, it should be noted that the outgoing terminals include fan outgoing terminals 105, frequency converter outgoing terminals 107, drive outgoing terminals 106, DC power supply outgoing terminals, and single-phase AC outgoing terminals 108, all of which are disposed on the housing.

[0114] The input terminal 104 is connected to the main power supply module 2, and the main acquisition unit 21 is set on the power supply line connected to the input terminal 104 and the main power supply module 2.

[0115] The stop and reset button 102 is connected to the microcontroller through a reset circuit. The reset circuit includes a VCC_5V voltage, a resistor, and a capacitor connected in sequence. The connection point of the resistor and capacitor is connected to the reset pin of the microcontroller. The connection point of the resistor and capacitor is also grounded through the stop and reset button.

[0116] In some embodiments, the data acquisition and processing device is further provided with a cooling fan and a temperature sensor, the temperature sensor and the cooling fan being connected to the control module respectively;

[0117] The control module controls the operation of the cooling fan based on the temperature detected by the temperature sensor. When the temperature exceeds the warning threshold, the control module automatically shuts down and disconnects all power supply lines. The microcontroller input port is also connected to a temperature sensor. Here, a Pt100 is used to collect temperature signals. The collected temperature signals are processed through A / D conversion and compared with a preset threshold. If the temperature exceeds the threshold, the microcontroller outputs a temperature alarm signal to alert the device to overheating. The collected temperature signal is also output to the display module for display.

[0118] In some embodiments, such as Figure 1 and 2 As shown, a mounting plate 20 is provided on the back of the housing corresponding to the front, and the mounting plate 20 is provided with mounting holes 201;

[0119] The housing 10 has heat dissipation holes 103 on its side and top surfaces.

[0120] The housing material includes, but is not limited to, aluminum. By setting corresponding input terminals, output terminals, display modules, stop and reset buttons on the housing, the complex wiring of the electrical control cabinet can be reduced, enabling modular wiring and systematic wiring. Wiring is more convenient, occupies less space, and has a higher degree of integration.

[0121] The device also includes a communication module connected to the control module, the communication module having a communication interface 112 for connecting to external devices. The communication interface 112 is located on the front of the housing 10.

[0122] The control module communicates with the host computer via a communication interface to display the output information.

[0123] The control module, acquisition unit, communication module, and various switch units are all mounted on the PCB board; the wiring connections are all made inside the PCB through copper plating or jumpers to achieve an overall closed-loop feedback system.

[0124] This system enables stable 380V, 220V, 24V, and 12V voltage outputs. The integrated internal modules allow for comprehensive control of the external circuitry. With a switching current capacity of up to 40A, the highly integrated multi-circuit switching design allows for simultaneous operation of fans, frequency converters, and drivers used in laser equipment. Compared to existing technologies, the independently designed voltage and current detection module can autonomously detect phase loss in the entire circuit. Furthermore, it eliminates the need for external meters to display the current, voltage, and power consumption of each branch.

[0125] like Figure 4 As shown in the figure, this embodiment of the invention also provides a laser device integrated strong and weak current data processing method, applied to the system described in the above embodiment, the method comprising the following steps:

[0126] Step 1: Read the data collected by each acquisition unit;

[0127] Step 2: After the data is successfully read, compare the read data with the preset value to determine if it exceeds the range;

[0128] If the data exceeds the range, proceed to step 3; if the data does not exceed the range, continue to step 1 to read the data collected by each acquisition unit.

[0129] Step 3: Output feedback value.

[0130] Step 4: Read the feedback value;

[0131] Step 5: Determine whether the read feedback value is a fault value;

[0132] If yes, proceed to step 6; if no, proceed to step 7.

[0133] Step 6: Disconnect all power supply lines and output fault values ​​to the display module for display;

[0134] Step 7: Read the data collected by each acquisition unit; proceed to step 8;

[0135] Step 8: Once the data is successfully read, the read voltage, current, and temperature values ​​will be output and displayed;

[0136] Step 9: Calculate the actual power consumption based on the read voltage and current, and display the calculated power consumption.

[0137] It should be further explained that the steps for determining whether the read feedback value is a fault value include:

[0138] Step 81: Determine whether the read feedback value can be reset;

[0139] If yes, proceed to step 82; if no, proceed to step 83.

[0140] Step 82: Feedback the fault value and output a prompt message indicating that a reset operation is possible;

[0141] Step 83: Determine if the read feedback value is a fault value, and display the fault value.

[0142] In some embodiments, when the display module is an industrial control display screen, the method further includes:

[0143] Read the external mapping table;

[0144] Determine whether the laser device connected to the data acquisition and processing device is authorized;

[0145] If not, disconnect all power supply lines and output an "unauthorized" message to the display interface.

[0146] If so, the steps are as follows: Read the data collected by each acquisition unit.

[0147] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, the invention is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the invention by those skilled in the art without departing from the spirit and essence of the invention, and such modifications or substitutions should all be within the scope of the invention.
