Detailed Description
An induction water control device with master-slave double induction units is structurally shown in figure 1, and comprises a master induction unit 4, a slave induction unit 5, a pulse electromagnetic valve 3, a pulse electromagnetic valve driving unit 2, a central control module 1, a display unit 6 and a power supply 7, wherein the output end of the power supply is connected with the input end of the central control module and is used for directly or indirectly providing working power supply for the central control module and other units; the output end of the central control module is respectively connected with the display unit and the controlled end of the pulse electromagnetic valve driving unit, and the output end of the pulse electromagnetic valve driving unit is connected with the controlled end of the pulse electromagnetic valve; the central control module is respectively connected with the main sensing unit and the auxiliary sensing unit, and is not only used for receiving signals of whether the main sensing unit and the auxiliary sensing unit sense objects or not, but also used for controlling working devices of the main sensing unit and the auxiliary sensing unit. The main sensing unit and the auxiliary sensing unit in the invention are one of a mechanical sensor, a photoelectric sensor, an ultrasonic sensor and a capacitance sensor.
In the invention, the main sensing unit can control the on or off of the pulse electromagnetic valve through the central control module after sensing that an object exists; the sensing function of the slave sensing unit to the object can be started through the central control module.
The sensing function of the slave sensing unit to the object is started or closed under the instruction of the central control module through the motion condition of the master sensing unit when the object exists. When the pulse electromagnetic valve is in a turn-off state and the main sensing unit senses that an object exists, the central control module controls the pulse electromagnetic valve and the auxiliary sensing unit to work in one of the following three working modes: 1) opening the pulse electromagnetic valve and not starting the induction function of the slave induction unit to the object, 2) not opening the pulse electromagnetic valve but starting the induction function of the slave induction unit to the object, and 3) opening the pulse electromagnetic valve and starting the induction function of the slave induction unit to the object.
The secondary sensing unit can control the pulse electromagnetic valve to be switched on or switched off through the central control module according to whether the secondary sensing unit senses the existence condition of an object or not only after the sensing function is switched on; in the case where it is not turned on for the object sensing function, the slave sensing unit has no influence on the turn-on and turn-off of the pulse solenoid valve.
The specific working flow of the present invention is shown in fig. 2 and described in detail below.
The pulse electromagnetic valves in the induction water control device have only two working states, and are switched on or switched off.
Under the state that pulse solenoid valve is in opening, will close pulse solenoid valve when main response unit senses the object existence once more, when the object existence is not sensed to the follow response unit, also can close pulse solenoid valve.
Under the state that the pulse electromagnetic valve is in turn-off, whether the main sensing unit senses the existence of the object is firstly judged, and when the object is sensed, the time for the sensed object to continuously exist is judged.
When the sensed object continuously exists for more than 5 seconds and disappears, the pulse electromagnetic valve enters a long-opening state until the main sensing unit senses the existence of the object again and then is turned off.
When the time of the sensed object continuously existing is less than 5 seconds, the pulse electromagnetic valve is switched on or off by whether the sensing unit senses the object or not. That is, when the presence of an object is sensed from the sensing unit, the pulse solenoid valve is turned on, and when the presence of an object is not sensed from the sensing unit, the pulse solenoid valve is turned off.
The above simple flow analysis illustrates the master-slave relationship between the master sensing unit and the slave sensing unit: the main induction unit can independently and directly close or open the pulse electromagnetic valve, and the slave induction unit can open the pulse electromagnetic valve only after the main induction unit induces an object.
The present invention will be described in further detail with reference to specific examples.
In this embodiment, the following four motion states of the object can be set: the sensed object exists continuously for a long time, intermittently for a certain period of time, briefly for a short time, or continuously for a slightly longer brief period of time. When the pulse electromagnetic valve is in a turn-off state and the main sensing unit senses the existence of an object, the central control module controls the pulse electromagnetic valve and the slave sensing unit to work in the following modes corresponding to the three motion states.
When the main sensing unit senses that the object continuously exists for a long time, for example, the object exists for more than 5 seconds, the central control module opens the pulse electromagnetic valve and does not start the sensing function of the slave sensing unit on the object. In this state, the central control module turns off the pulsed solenoid valve according to one of the preset modes: when the main sensing unit senses the existence of the object again or arrives at the preset time.
When the main sensing unit senses that the object intermittently exists within a certain time, for example, the object intermittently appears for more than 3 times within 2 seconds, the pulse electromagnetic valve is not opened, and the sensing function of the slave sensing unit on the object is started. In this state, the central control module controls the pulse solenoid valve to be turned on and off according to a preset pattern according to whether the sensing unit senses the existence of the object, for example, when the sensing unit senses the existence of the object, the pulse solenoid valve is turned on and off according to a preset time period.
When the main sensing unit senses that the object exists for a short time, for example, the object exists for less than 1 second, the pulse electromagnetic valve is not opened, and the sensing function of the slave sensing unit on the object is started. In this state, the central control module opens the pulse electromagnetic valve according to the sensing of the object from the sensing unit, and closes the pulse electromagnetic valve when the object is not sensed. Meanwhile, no matter whether the slave sensing unit senses the object or not, as long as the master sensing unit senses the object again, the central control module closes the pulse electromagnetic valve immediately, and the object sensing function of the slave sensing unit is closed.
When the main sensing unit senses that the object continuously exists for a short time, for example, the continuous existence time of the object is 2 seconds to 4 seconds, the pulse electromagnetic valve is opened, and meanwhile, the sensing function of the slave sensing unit to the object is started. In this state, the central control module turns off the pulse electromagnetic valve after the preset time is reached, but does not turn off the induction function of the slave induction unit to the object; when the sensing unit senses the existence of the object again, the central control module turns on the pulse electromagnetic valve again, turns off the pulse electromagnetic valve again after the preset time is up, and does not close the sensing function of the sensing unit to the object. The above steps are repeated in a circulating mode until the main sensing unit senses the object again, the central control module immediately closes the pulse electromagnetic valve, and simultaneously closes the object sensing function of the auxiliary sensing unit.
After the induction function of the slave induction unit to the object is started, under the state that the pulse electromagnetic valve is switched on, when the master induction unit induces the existence of the object again, the central control module closes the induction function of the slave induction unit to the object and switches off the pulse electromagnetic valve; or the main sensing unit does not sense the existence of the object within a preset time, the central control module closes the sensing function of the auxiliary sensing unit to the object and turns off the pulse electromagnetic valve. After the sensing function of the slave sensing unit to the object is started, the slave sensing unit does not sense the existence of the object within a preset time period under the state that the pulse electromagnetic valve is turned off, and the central control module closes the sensing function of the slave sensing unit to the object.
The above embodiments are only used to illustrate the working principle of the present invention, and the present invention is not limited to the operation of setting the master-slave sensing units and the pulse solenoid valves according to the motion state of the object proposed in the embodiments in practical application, but all the embodiments fall within the scope of the claims of the present application, that is, the sensing water control device adopts the master-slave dual sensing units to control the water flow, and all the embodiments fall within the scope of the present invention.
