Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in further detail below with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.
It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a schematic structural diagram of a heating element detection system according to an embodiment of the present invention, which is applicable to a situation of performing automatic detection on a heating element fault based on PID control, and the specific structure of the heating element detection system includes:
the heating system comprises a component heating module 110, a current transformer 120, a PLC control module 130 and a heating power supply control module 140; the element heating module 110 is electrically connected to the current transformer 120 and the heating power control module 130, respectively, and the PLC control module 130 is electrically connected to the current transformer 120 and the heating power control module 140, respectively;
the heating power supply control module 140 is configured to provide power to the element heating module 110 according to the received heating start signal output by the PLC control module 130 after the PLC control module 130 determines that the PID controller is turned off;
the current transformer 130 is configured to acquire a heating current value of the element heating module 110 in a heating state;
the PLC control module 130 is configured to determine a target current value based on the heating current value, and determine fault detection information corresponding to the heating element according to the target current value.
Wherein the element heating module 110 is used to provide a heating function for the heating element.
It should be noted that the PID controller is used for temperature adjustment, and the transient current of the heating element may be large due to too frequent on/off of the PID controller, so that the PID controller may be turned off for a short time to maintain the stability of the current, and the current is not affected by turning off the PID controller in a short time.
In this embodiment, after the PLC control module 130 determines that the PID controller is turned off, the heating power control module 140 provides power to the element heating module 110 within the preset time period of the turn-off of the PID controller, so that the element heating module 110 heats with the rated power as the heating element, and meanwhile, the problem of large current at the moment of starting the element heating module 110 is avoided.
It can be understood that, after the PID controller is turned off for a preset time period, the PLC control module 130 outputs a heating-off signal to the heating power control module 140 at the end time of the turn-off of the PID controller, so as to save cost.
After the element heating module 110 starts to heat the heating element, the current transformer 120 acquires an instantaneous current value of the element heating module 110, that is, a heating current value when the element heating module 110 is in a heating state, and the PLC control module 130 acquires the instantaneous current value of the element heating module 110 acquired by the current transformer 120.
The PLC control module 130 selects a more accurate current value as the target current value based on the instantaneous current value of the element heating module 110.
On the basis of the above embodiment, the PLC control module is further configured to output an alarm signal if it is determined that the heating element is in a fault state according to the fault detection information.
Specifically, the target current value is compared with the theoretical current value, when the difference value between the target current value and the theoretical current value is within a preset current difference value threshold range, the deviation between the target current value and the theoretical current value is not large, and the heating element is continuously monitored; when the difference value between the target current value and the theoretical current value exceeds the preset current difference value threshold range, the deviation between the target current value and the theoretical current value is determined to be large, the heating element is determined to have a fault, and the PLC control module 130 outputs an alarm signal so as to give an early warning to a person skilled in the art through the alarm signal.
The failure detection information may be heating element normal information or heating element failure information, and is specifically determined by the currently detected current value, and this embodiment is merely illustrative and not limited thereto.
For example, the PID controller is turned off for 3 seconds, and the PLC control module 130 outputs a heating on signal to the heating power control module 140 at the starting time of the turn-off of the PID controller, so as to control the heating power control module 140 to supply power to the element heating module 110, so that the element heating module 110 heats with the rated power as the heating element. The PLC control module 130 obtains an instantaneous current value of the element heating module 110 at the second collected by the current transformer 120 as a target current value, compares the instantaneous current value of the element heating module 110 at the second with a theoretical current value, and when the deviation between the instantaneous current value at the second and the theoretical current value is large, the PLC control module 130 outputs an alarm signal to warn a person skilled in the art through the alarm signal, and if the deviation between the instantaneous current value at the second and the theoretical current value is not large, the heating element detection is continued.
It should be noted that the heating element detection system provided in this embodiment may perform automatic detection once within a preset time length, that is, each time a preset time length passes through by the PLC control module, the PLC control module outputs a heating start signal to the heating power supply control module, controls the heating power supply control module to provide power for the element heating module, and then performs the operation of determining the fault detection information corresponding to the heating element as described above.

The PLC control module 130 outputs a heating off signal to the control terminal of the ac contactor 141 to turn off the ac contactor 141, and the heating power supply 142 stops supplying power to the element heating module 110.
The heating power source 142 may be a conventional heating element detection power source, and the embodiment is not limited to any particular type of the heating power source 142.
The ac contactor 141 may be a conventional ac contactor such as CJ10, CJ40, CJ12, CJ20 and CJX, 3TB, B series of ac contactors introduced, and the embodiment is not limited to any specific type of the ac contactor 141.
