Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment provides an automatic control method for an agricultural terminal, which is characterized in that the method carries out the operation of an execution module by collecting data acquired on an agricultural site, and the operation of the execution module at least meets the following priority:
a. the execution module conforms to the security setting;
b. the execution module acts according to a preset delay interval; the execution module comprises a plurality of execution terminals, and when one of the execution terminals with mutually exclusive functions acts, the execution terminal with mutually exclusive function stops;
c. the execution module comprises a plurality of execution terminals, and when one of the execution terminals with the functions linked acts, the execution terminal acts in linkage with the execution terminal;
d. comparing the deviation of the acquired data with a preset value, executing module action when the deviation value exceeds a preset range, and stopping the execution module when the deviation is recovered to the preset range and the deviation from the preset value is greater than a drop value;
e. the execution module is controlled through a remote network.
The safety setting comprises one or more of switch control, voltage detection, phase sequence detection and triggering thermal protection. For example, when the switch control (emergency stop switch) is turned off, the whole machine control is completely turned off, when the voltage is too high or too low, the power is cut off, when the phase sequence is wrong, the whole machine control is completely turned off, or the whole machine is not operated when the phase is lost, and the triggering thermal protection can be used for performing cutting-off control on the part where the triggering thermal protection occurs.
As shown in fig. 1, the execution module is controlled by a relay. The delay interval comprises a relay pre-working interval T1, a working process interval T2 and a working post interval T3, the relay waits for the action after the completion of the pre-working interval T1 after receiving the trigger signal, if a stop signal is not received all the time, the relay automatically stops after the completion of the working process interval T2, and when the action stops and receives the action signal, the relay completes the action after the working post interval T3.
Some execution terminals and other execution terminals cannot be started at the same time, for example, if the execution terminal a and the execution terminal B are set to be mutually exclusive, the execution terminal B will be automatically closed when the execution terminal a is started, and the channel of the execution terminal a will be automatically executed when the execution terminal B is started. And the execution terminal mutual exclusion can be applied to controlling the positive and negative rotation of the motor. For example, if the motor is controlled by the execution terminal a to rotate forward and the motor is controlled by the execution terminal B to rotate backward, a mutual exclusion logic must be set, otherwise, the execution terminal a and the execution terminal B may trigger a short circuit due to simultaneous operation caused by misoperation, resulting in loss.
Execution terminal linkage refers to a logic that when execution terminal a is working, execution terminal B and execution terminal C are to work together, but execution terminal B and execution terminal C can work independently. The logic of executing the terminal linkage can be applied to a main switch and a branch switch, for example, if the executing terminal a-the executing terminal D are four-way lights, and if the executing terminal E is set to simultaneously turn on or off the four-way lights, the executing terminal E is set to execute the executing terminal a-the executing terminal D in linkage.
The system can be used as an automatic control system according to the numerical value of the sensor, the automatic control system consists of a plurality of alarm values, the alarm values comprise an alarm upper limit and an alarm lower limit, and when the reading of the sensor is less than or equal to the alarm lower limit or the reading of the sensor is more than or equal to the alarm upper limit, the two conditions meet the alarm condition, and an alarm is triggered.
And comparing the deviation of the acquired data and a preset value to be a drop value which can be set by the equipment, wherein the drop value refers to triggering an alarm action after exceeding the upper alarm limit and eliminating the alarm after the reading of the sensor falls back to a drop area behind the upper alarm limit and the lower alarm limit. For example: setting an alarm upper limit to be 100ppm, setting a drop value to be 10ppm, and triggering an alarm when the reading value is increased to exceed 100 ppm; when the reading falls back to 99ppm from 105ppm, and the reading is less than the upper alarm limit but does not exceed the falling area, the deviation of the reading from the preset value is 1ppm and less than 10ppm of the preset value, so the alarm is still continued until the reading falls back to below 90ppm, and the alarm is not eliminated.
In an automatic temperature control process as shown in fig. 2, when the air temperature is abnormal, the control module performs a logic judgment. When the temperature is too high, the side fan exhausting air outwards is opened to discharge the heat in the environment outwards, and when the temperature is too low, the hot air fan supplying air inwards is opened to raise the temperature in the environment, and the corresponding fan is closed after the temperature returns to normal. And the process can be remotely operated through the cloud platform.
As shown in fig. 3 and 4, the automatic control device for the agricultural terminal comprises a control module, a data acquisition module, an execution module and a power supply module, wherein the data acquisition module and the execution module are in signal connection with the control module, and the power supply module is electrically connected with the execution module.
The data acquisition module comprises various sensors such as an air temperature sensor, an air humidity sensor, a light intensity sensor, a carbon dioxide sensor, a soil temperature sensor and a soil humidity sensor and is used for acquiring physical quantity information. The control module can use a single chip microcomputer or a PLC and the like and is used for realizing the control of various priority judging and executing modules in the control method. The power supply module is provided with an emergency stop switch and an open-phase sequence protection relay. The execution module comprises a plurality of execution terminals, and each execution terminal is connected with one thermal overload relay.
