In the prior art, the scheme that the unit replaces the filter at regular time does not consider that different water qualities have different losses to the filter, so that the time for replacing the filter cannot be accurately controlled to solve the problem, this embodiment provides a blockage determination method, and fig. 2 is a flowchart of the blockage determination method according to the embodiment of the present invention, and as shown in fig. 2, the method includes:
s101, after the unit is put into operation, acquiring a corresponding blockage judgment parameter when a blockage switch acts.
The working principle of the blocking switch is that when the water flow in a circulating system of the unit is lower than a fixed value, the blocking switch can be triggered to act, and during specific implementation, the water flow in the system is reduced step by controlling the gear of a water pump in the unit until the blocking switch is triggered to act; and acquiring a blockage judgment parameter at the action moment of the blockage switch.
And S102, judging whether the unit meets the blockage judgment condition according to the corresponding blockage judgment parameter when the blockage switch acts.
The clogging determination parameter includes at least one of: water pump gear, pressure at the water pump discharge end. Under the normal condition, when the gear of water pump or the pressure of water pump drainage end reduce to the certain extent, the jam switch will move, when the unit takes place to block up, the resistance in the circulation system of unit can increase, and then lead to the resistance increase that rivers need overcome, under the unchangeable circumstances of gear of water pump, the discharge in the circulation system can be compared and reduce when not taking place to block up, if guarantee discharge and do not take place to block up when keeping level, need improve the gear of water pump or the pressure of water pump drainage end, because the theory of operation of jam switch is when discharge in the circulation system of unit is less than a fixed value, will trigger the action, consequently, under the circumstances of taking place to block up, the gear of water pump or the pressure of water pump drainage end when the jam switch action will be higher than under the circumstances of not taking place to block up, consequently, can judge the parameter through the jam that corresponds when the jam switch takes place to move and judge that the unit satisfies the jam judgement condition.
According to the blockage judging method, after the unit is put into operation, the corresponding blockage judging parameter when the blockage switch acts is obtained, whether the unit meets the blockage judging condition or not is judged according to the corresponding blockage judging parameter when the blockage switch acts, whether the unit is blocked or not can be accurately judged according to the opportunity operation condition of the unit, the opportunity for replacing the filter is accurately controlled, and the problems that waste is caused in advance when the filter is replaced or the unit is stopped due to the fact that the filter is replaced later are solved.
According to the above, when the blockage occurs, the pressure at the gear of the water pump or the water discharge end of the water pump when the blockage switch operates is higher than that when the blockage does not occur, and when the pressure is higher to a certain degree, the blockage situation is serious, so that whether the unit meets the blockage judgment condition or not is judged according to the corresponding blockage judgment parameter when the blockage switch operates, and the method comprises the following steps: judging whether the difference value between the blockage judging parameter and the reference value of the blockage judging parameter is larger than a preset threshold value or not; if yes, judging that the unit meets the blockage judgment condition; if not, judging that the unit does not meet the blockage judgment condition, controlling the unit to normally operate under the condition that the blockage judgment condition is not met, waiting for receiving an instruction for stopping operation, judging whether the unit meets the blockage judgment condition or not according to the blockage judgment parameter corresponding to the action of the blockage switch and the reference value of the blockage judgment parameter again after the instruction for stopping operation is ended, or re-acquiring the blockage judgment parameter corresponding to the action of the blockage switch after the unit is put into operation for the next time, and judging whether the unit meets the blockage judgment condition or not. The reference value of the blockage judging parameter refers to the corresponding blockage judging parameter when the blockage switch is operated under the condition that the unit is not blocked.
In addition, under the general condition, what the jam switch took place to act corresponds, the gear of the water pump of unit and the maximum gear of water pump differed more, the pressure of water pump drainage end will be with the maximum value that the pressure of water pump drainage end can reach when unit operation differed also more, however, if take place to block up, the difference between the gear of the water pump of unit and the maximum gear of water pump will dwindle, the pressure of water pump drainage end will also dwindle with the maximum value difference that the pressure of water pump drainage end can reach when unit operation, consequently, whether the unit satisfies the jam judgement condition according to the jam judgement parameter that corresponds when the jam switch took place to act judges the condition, can also include: and judging whether the unit meets the blockage judgment condition or not according to the blockage judgment parameter corresponding to the action of the blockage switch and the maximum value of the blockage judgment parameter.
Specifically, judging whether the unit meets the blockage judgment condition according to the blockage judgment parameter corresponding to the action of the blockage switch and the maximum value of the blockage judgment parameter comprises the following steps: judging whether the difference value between the corresponding blockage judging parameter and the maximum value of the blockage judging parameter is smaller than a preset difference value when the blockage switch acts; if so, judging that the unit meets the blockage judgment condition; and if not, judging that the unit does not meet the blockage judgment condition.
If the unit is judged to meet the blockage judgment condition only once, the unit is considered to be blocked, and the judgment is inaccurate, so that in order to ensure the judgment accuracy, after the unit is judged to meet the blockage judgment condition, the method further comprises the following steps of: judging whether the accumulated times of the unit meeting the blockage judgment condition is greater than the preset times or not; if yes, the control unit sends out a blockage prompt to prompt a user to replace the filter.
In order to find out the condition of unit blockage in time, the method further comprises the following steps: and after the unit receives the instruction of stopping running, judging whether the unit meets the blockage judgment condition again according to the corresponding blockage judgment parameter when the blockage switch acts and the reference value of the blockage judgment parameter.
According to the foregoing, it is necessary to judge whether the blockage judging condition is satisfied by comparing the blockage judging parameter when the blockage switch is triggered to operate in the unit operation process with the blockage judging parameter corresponding to the unit when the unit is not blocked, and therefore, when the unit is not blocked, the blockage judging parameter corresponding to the unit when the blockage switch operates, that is, the reference value of the blockage judging parameter, is required to be obtained, the unit undergoes a debugging process of automatic evacuation of the whole unit in each installation and debugging process, and the unit which has just been debugged cannot be blocked, and the reference value of the blockage judging parameter can be obtained just after the system finishes evacuation, and therefore, before the unit is put into operation, the method further includes: and after the unit is debugged and emptied, determining a reference value of a blockage judgment parameter of the unit. The method specifically comprises the following steps: the gear of a water pump in the control unit is gradually reduced, for example, the gear of the water pump is controlled to be reduced by one gear every 30s until the action of a blocking switch is triggered; and acquiring a blockage judgment parameter at the action time of the blockage switch as a reference value of the blockage judgment parameter.

And S4, receiving the normal startup operation system hardware initialization of the startup instruction set, and simultaneously performing blockage detection.
And S5, judging whether the unit meets the blockage judgment condition, if so, executing the step S6, and if not, executing the step S11.
And S6, storing the blocking mark value B = B +1 by the unit, and normally operating the unit. And the blockage mark value B is used for representing the times of judging that the unit meets the blockage judging condition.
And S7, after the unit finishes running and receives a shutdown instruction, the water pump is turned off in a delayed mode and blockage detection is carried out.
And S8, judging whether the unit meets the blockage judgment condition, if so, executing the step S9, and if not, executing the step S10.
And S9, storing the new blockage mark value, normally shutting down the computer, and directly executing the step S4 after next startup, wherein the blockage mark value B = B + 1.
And S10, resetting the blockage mark value B to be 0, normally shutting down the unit after storing the blockage mark value, and directly executing the step S4 after starting up the unit next time.
And S11, after resetting the blocking mark value B to 0, the unit continues to normally operate, and then the step S7 is executed.
When the unit receives a starting instruction, the unit carries out initialization action, all water valves are opened, after the initialization of free running of the water pump is completed, the unit is operated to the highest gear and then is adjusted down every 30s, until a water pump gear Dp2 is recorded after the action of a blocking switch, dp1 is compared with Dp2, if the gear difference Dp2-Dp1 is larger than 3 or the Dp2 is less than 3 from the maximum gear of the water pump, the blocking judgment condition is met, a blocking mark value B = B +1, the unit normally operates at the moment, the operation judgment is carried out when the unit is shut down, the unit is shut down in a delaying mode, the unit is subjected to blocking detection judgment after the water temperature reaches the temperature close to the indoor environment temperature, if the blocking judgment condition is met, the blocking mark value B = B +1 is reset to 0, namely B =0, the system normally waits for next starting up, and a display of the unit prompts a filter replacing code when the system normally waits for next starting up and the system detects that B =3 (can be set) after the blocking judgment of the blocking of the unit is completed, and a client is informed to contact with a filter replacing in advance.
In practical application, in order to ensure the safe and stable operation of the unit and prevent the fault shutdown caused by the false alarm of the unit, the idling of the water pump or the cavitation influence on the service life caused by the operation of a circulating system of the unit with air, the unit can experience the whole automatic debugging and emptying process of the unit in the installation and debugging process every time, the embodiment just utilizes the point, and the gear of the water pump is controlled to descend step by step after the system finishes emptying until the action of a blocking switch is triggered. When a user starts the machine each time, a blockage judging program is operated, a blockage mark value is stored in a database and is compared according to the action condition of the hardware, a blockage judging parameter and a reference value of the blockage judging parameter at this time, blockage judgment is carried out, a judging result is recorded, judgment is carried out after the operation is finished, and when the blockage judgment is detected three times (a set value can be set) continuously, a machine set sends a system prompt to the user and reminds the user to replace a filter.
The control method of the embodiment can realize that the unit autonomously finishes the work of judging whether the unit is blocked, informs a user through the prompt code, and enables the user to contact service personnel in advance for maintenance, thereby avoiding the problems of machine halt and downtime caused by blockage in advance, avoiding the problem of blockage-free filtration, and reducing and improving the utilization rate of the service personnel and the operation cost.
