Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Fig. 1-6 are schematic diagrams of an external structure and an internal connection of an agricultural greenhouse control cabinet according to an embodiment of the present application. The embodiment of the application provides an green house switch board, include:
a controller;
a mode switching knob capable of switching to an emergency mode;
one end of the emergency switch is connected with the power supply when the mode switching knob is switched to the emergency mode, and the other end of the emergency switch is electrically connected with one end of the emergency switch;
the control branch circuit comprises a contact coil and a normally closed switch which are connected in series, one end of the contact coil is electrically connected with the output end of the controller and the other end of the emergency switch, two ends of the normally closed switch are respectively electrically connected with the other end of the contact coil and execution equipment in the agricultural greenhouse, and the contact coil in one control branch circuit is used for controlling the on-off state of the normally closed switch in the other control branch circuit.
The control cabinet mainly comprises a cabinet body and a controller arranged in the cabinet body, wherein the cabinet body is provided with a cabinet door, the cabinet door is opened in a horizontal rotation mode, and a mode switching knob and an emergency switch are arranged on the cabinet door so as to be convenient for farmers to operate. Besides the mode switching knob and the emergency switch, a power button and a voltmeter are further arranged on the cabinet door, the power button is connected between the main power supply and the controller, and the voltmeter is used for detecting and indicating voltages between any two phases in the three-phase power supply respectively.
In the embodiment of the application, the emergency switches have 6 groups, each group having 2 emergency switches, so that the 6 groups of emergency switches are respectively used for controlling the operating states of the 6 execution devices. Specifically, the execution device is mainly divided into a roller shutter motor and a wind gap motor, wherein the roller shutter motor is a 220V or 380V alternating current motor, the wind gap motor is a 24V direct current motor, the number of the roller shutter motors is 2, the roller shutter motors are respectively controlled by 4 emergency switches SB1-SB4, the number of the wind gap motors is 4, and the wind gap motors are respectively controlled by 8 emergency switches S5-S12.
Further, each two control branches are electrically connected with the same executing device, and the two control branches electrically connected with the same executing device are respectively used for controlling the forward work and the reverse work of the executing device. For example, the two control branches 1 in fig. 2 are rolled up and 1 are laid out as a group, wherein after the contact coil KM1 in the rolling up of the control branch 1 is energized, the normally closed switch KM1 in the laying out of the control branch 1 can be controlled to be turned off, so that the two control branches controlling the same executing device cannot be simultaneously turned on, and therefore the executing device only works in the forward or reverse rotation mode at the same time.
When the mode switching knob is switched to the emergency mode, the controller works normally, and the output state of the output end is not changed. Thus, when the controller is normal, the executing device will operate normally under the control of the controller, whether or not to switch to the emergency mode. When an abnormality occurs in a certain output end of the controller, the farmer can switch to the emergency mode and press the corresponding emergency button. The emergency button in the application is a normally open button which is in an off state when not pressed, and when pressed, the emergency button is connected with the contact coil on the corresponding control branch, so that the contact coil is electrified and the normally closed switches in other control branches in the same group are controlled to be disconnected.
Taking the control branch 1 rolling up and 1 spreading as an example, in a normal state, when the 1 roller shutter motor does not need to work, the 05 pin of the controller does not output a signal, so that the contact coil KM1 is not electrified. When the 05 pins are abnormal, the output signal is used for electrifying the contact arm KM1, the roller shutter motor is controlled to work to roll up the sun-shading curtain, at the moment, a farmer can rotate the mode switching knob to an emergency mode and press the emergency switch SB2, at the moment, the contact arm KM2 in the process of controlling the branch 1 to be spread is switched on, and the normally closed switch KM2 in the process of controlling the branch 1 to roll up is switched off under the control of the contact arm KM2, so that the abnormal work of the roller shutter motor is finished. Moreover, the normal pins of the controller are not affected, so that all the execution devices are not powered off, and the execution devices under abnormal control are only disconnected.
In one possible embodiment, the mode switching knob is also capable of switching to a local mode in which the emergency switch is electrically connected to the input of the controller.
As shown in fig. 5 and 6, the emergency switches SB1-SB12 are normally open buttons, so when pressed, they will send a high level signal to the corresponding input terminal pin of the controller, and after detecting the high level signal, the controller will control the corresponding output terminal pin to output a signal, thereby controlling the corresponding control branch to be turned on, and finally controlling the corresponding execution device to work.
In one possible embodiment, the mode switch knob is further capable of switching to a remote mode in which the controller receives a remote control signal.
Illustratively, as shown in fig. 6, the mode switching knob SA1 will be connected to the input of the controller when switching between the local and remote modes, except that the connection is made to a different input pin of the controller, and when the mode switching knob SA1 is switched to the local mode or the remote mode, a continuous high level signal will be received at the corresponding input pin of the controller, and the corresponding mode of the controller will be activated under the continuous input of the high level signal. In the local mode, the controller receives the high-level signal input by the input end pin, then switches on the corresponding control branch circuit and shields the remote control signal, and in the remote mode, the controller shields the high-level signal input by the input end pin and receives the remote control signal.
In one possible embodiment, an auxiliary switch is electrically connected to the input of the controller, the auxiliary switch changing the on-off state under control of the contact coil.
The auxiliary switches are illustratively normally open switches. As shown in fig. 5, the auxiliary switches KM1-KM4 are turned on and off under the control of the contact lines KM1-KM4, respectively, specifically, when one of the contact lines KM1-KM4 is turned on, the corresponding one of the auxiliary switches KM1-KM4 is also turned on.
Further, the auxiliary switch in the application works in both the local mode and the emergency mode, taking the auxiliary switch KM1 as an example, after the emergency switch SB1 is pressed briefly in the local mode, the 10 pin at the input end of the controller receives a high-level pulse signal, and in the high-level duration of the pulse signal, the 05 pin at the output end of the controller outputs a signal, at this time, the control branch 1 is turned on, the contact coil KM1 is also electrified, and then the normally closed switch KM1 is opened, and meanwhile, the auxiliary switch KM1 is also closed. When the auxiliary switch KM1 is continuously closed, the control branch 1 is continuously turned on, the self-locking function is realized, and a farmer does not need to continuously press the emergency switch.
In the emergency mode, when the emergency switch SB1 is pressed down briefly, the control branch 1 is turned on, the contact coil KM1 is also energized, and the normally closed switch KM1 is further opened, and the auxiliary switch KM1 is also closed. When the auxiliary switch KM1 is continuously closed, the control branch 1 is continuously turned on, the self-locking function is realized, and a farmer does not need to continuously press the emergency switch.
In one possible embodiment, a plurality of sensors are also electrically connected to the output of the controller.
For example, as shown in fig. 2, the above-mentioned sensors may be sensors capable of collecting environmental data in the greenhouse, such as temperature, humidity, illumination, etc., and sequentially connected to pins 01-04 of the output end of the controller, where the sensors are connected to the output end of the controller to obtain power.
In one possible embodiment, the input of the controller is also electrically connected to a limiter.
As shown in fig. 5, the number of limiters in the present application is 4, namely, 1 roller shutter upper limiter SQ1, 1 roller shutter lower limiter SQ2, 2 roller shutter upper limiter SQ3 and 2 roller shutter lower limiter SQ4, and these limiters are respectively used for detecting the positions of 2 roller shutters after rolling or spreading, when the roller shutters are rolled or spread to the positions, the limiters will contact with the limiters in the corresponding positions, at this time, the limiters are disconnected, the input pins corresponding to the controller will receive a low level signal, and under the control of the low level signal, the controller will end the working state of the corresponding roller shutter motor, so as to avoid the damage of the roller shutters caused by the excessive rotation of the roller shutter motor.
While preferred embodiments of the present application have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the application.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present application without departing from the spirit or scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims and the equivalents thereof, the present application is intended to cover such modifications and variations.
