As preferably, described central processing unit (CPU) is also connected with display interface and keystroke interface, and described keystroke interface all realizes signal with described display interface and described central processing unit (CPU) and is connected.
As preferably, between described relay and sewage pump, be connected with A.C. contactor and hot protective relay in turn.
As preferably, also include power circuit, described power circuit includes+5V data acquisition unit control system working power and+24V ultrasonic wave sensor power supply
Pass through technique scheme, its working principle of the utility model is by installing intelligent control data acquisition unit, installing liquid level sensor, real-time level inside real-time detected set well, and the work of each pump is automatically controlled according to level condition, reach and ensure that the float switch position moment can be in harmonious proportion the object alleviating staff's work load.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is the schematic flow sheet of the sewage network pumping plant automatic controller disclosed in the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
The utility model provides sewage network pumping plant automatic controller, its working principle is by installing intelligent control data acquisition unit, installing liquid level sensor, real-time level inside real-time detected set well, and the work of each pump is automatically controlled according to level condition, reach and ensure that the float switch position moment can be in harmonious proportion the object alleviating staff's work load.
Below in conjunction with embodiment and embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of sewage network pumping plant automatic controller, include central processing unit (CPU), described central processing unit (CPU) is connected with analog quantity acquisition circuit and relay output control circuit, described analog quantity acquisition circuit and relay output control circuit realize signal with described central processing unit (CPU) respectively and are connected, described analog quantity acquisition circuit is connected with ultrasonic liquid level sensor, and described relay output control circuit is connected with several relay, and described relay is connected with sewage pump.
Described central processing unit (CPU) is also connected with display interface and keystroke interface, and described keystroke interface all realizes signal with described display interface and described central processing unit (CPU) and is connected.
A.C. contactor and hot protective relay is connected with in turn between described relay and sewage pump.
As preferably, also include power circuit, described power circuit includes+5V data acquisition unit control system working power and+24V ultrasonic wave sensor power supply
Concrete use step of the present utility model is as follows: more as shown in Figure 1, before sewage network pumping plant Intelligent auto-controller for vehicle carries out work, first set the sewage pump that will devote oneself to work, and the work liquid level of each sewage pump and to quit work liquid level.When ultrasonic sensor detects current level more than 2.000 meters, just control sewage pump 1 by relay output control circuit and devote oneself to work.At this moment may there are 2 kinds of situations in liquid level, and a kind is liquid level continuous decrease, and another a kind is that liquid level continues to raise.For the first situation when liquid level drops to 1.000 meters, central processing unit (CPU) detects that liquid level is lower than after 1.000 meters, controls sewage pump 1 quit work by relay output control circuit; For the 2nd kind of situation, when liquid level reaches 3.000 meters, central processing unit (CPU) controls sewage pump 2 and devotes oneself to work.At this moment should be continuous decrease according to design capacity liquid level, when liquid level is lower than 1.000 meters, central processing unit (CPU) controls sewage pump 1 simultaneously and sewage pump 2 quits work.
When the mud thickness in cesspool reaches 0.5 meter, the work liquid level of sewage pump 1 is set to 2.5 meters, and the liquid level that quits work is set to 1.5 meters; The work liquid level of sewage pump 2 is set to 3.5 meters, and the liquid level that quits work is set to 1.5 meters.So still can work on.
When mud thickness reaches the minimum altitude 1.0 meters of sewage pump installation, at this moment need to clear up mud, then amendment is devoted oneself to work after arranging again.
By above mode, sewage network pumping plant automatic controller provided by the utility model, its working principle is by installing intelligent control data acquisition unit, installing liquid level sensor, real-time level inside real-time detected set well, and the work of each pump is automatically controlled according to level condition, reach and ensure that the float switch position moment can be in harmonious proportion the object alleviating staff's work load.
Above-described is only the preferred implementation of sewage network pumping plant automatic controller disclosed in the utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
