Referring to Figures 1 and 2, the water tank detection system of the processing machine can implement a water tank detection method of the processing machine, and the water tank detection method of the processing machine includes the following steps 61 to 66.

In step 61, the control unit 5 receives the pumping motor current signals.

In step 62, the control unit 5 receives the current signals of the chip removal machines.

In step 63, the original signal of the water level is received by the control unit 5 .

In step 64 , the original signal of the ambient temperature is received by the control unit 5 .

In step 65 , the original temperature signal of the machining fluid is received by the control unit 5 .

In step 66 , the control unit 5 outputs the analyzed results to the processing machine 91 and the tablet computer 4 .

The control unit 5 can respectively execute a zeroth program, a first program, a second program, and a third program.

In the zeroth procedure, the control unit 5 executes the step 66 after executing the step 61 , the step 62 , the step 63 , the step 64 and the step 65 .

Referring to FIGS. 1 and 3 , in the first procedure, the control unit 5 executes the step 66 after executing the step 61 and the step 62 .

Referring to FIGS. 1 and 4 , in the second program, the control unit 5 executes the step 66 after executing the step 61 , the step 62 , the step 63 and the step 64 .

Referring to FIGS. 1 and 5 , in the third procedure, the control unit 5 executes the step 66 after executing the step 61 , the step 62 and the step 65 .

During use, the control unit 5 starts counting after starting up, then executes the zeroth program, and then repeatedly executes the first program. During the repeated execution of the first program, the control unit 5 can also execute the second program after every first predetermined time, and can execute the third program after every second predetermined time greater than the first predetermined time. In this embodiment, the first predetermined time is 4 minutes, and the second predetermined time is 5 minutes.

After the aforementioned procedures are executed, the analysis results are explained as follows: when the current value of each water pumping motor signal is in a different range, relevant information is displayed on the processing machine 91 and the tablet computer 4, for example, when the current is greater than or equal to 5.0A, the current value is too high; when the current is greater than or equal to 4.0A and less than 5.0A, the current value is high; low, and when the current is equal to 0A, the current value is abnormal, and when the current value is low or the current value is abnormal, it can be controlled to no longer supply power to the pumping motor 3 .

When the current value of each chip remover current signal is in different intervals, relevant information is displayed on the processing machine 91 and the tablet computer 4, for example, when the current is greater than or equal to 1.6A, the current value is too high; when the current is greater than or equal to 1.1A and less than 1.6A, the current value is high; When the value is low or the current value is abnormal, it can be controlled to no longer supply power to the chip remover 92.

When a temperature difference obtained by subtracting the temperature corresponding to the ambient temperature original signal from the temperature corresponding to the original signal of the machining fluid temperature is in different ranges, relevant information is displayed on the processing machine 91 and the tablet computer 4 , for example, when the temperature difference is greater than or equal to 10 degrees, it shows that the temperature is abnormal; when the temperature difference is greater than or equal to 6 degrees and less than 10 degrees, it shows that the temperature is gradually increasing;

When the original water level signal is in different intervals, relevant information is displayed on the processing machine 91 and the tablet computer 4, for example, when the distance from the water corresponding to the original water level signal is greater than or equal to 232mm, it displays 0% water level; level, and when the distance between the original signal of the water level and the water is greater than or equal to 60mm and less than 120mm, it displays 75% of the water level, and when the water level is 0% of the water level or 25% of the water level, it can be controlled to stop and no longer supply power to the pumping motor 3.

Further, if the water level does not return to a standard height within a return time after the pumping motor 3 is started, the return speed is abnormal, and in the case of abnormal return speed, it can be further judged that if the current water level drops by 15% compared with the initial water level, the return water filter 22 is in a clean filter state, and an abnormal condition is triggered once when it does not return to the standard height within 4 minutes.

Referring to FIGS. 1 and 6, in addition, the aforementioned implementation of the zeroth program, the first program, the second program, and the third program is implemented after compiling the process in a programmed manner. Therefore, another implementation as shown in FIG.
