The presented agricultural invention and apparatus here shown and disclosed was developed for peoples in undeveloped countries, peoples affected by the changing climates to reduce water usage and reduce electricity usage, bringing more water retention in the soils used for growing food all year round, for heating and cooling purposes of food and peoples living areas. The invention presented here is an apparatus used with a generation of electricity apparatus that utilizes a plurality of solar photo voltaic panels in a rack mounting structure utilizing various apparatus for increasing water irrigation, reduce water usages, and reduce electricity usage costs and supply at a specific spatial point area. The invention was developed to help people in rural un developed areas as well as cities and industrial growing areas. Also included is an autonomous Virtual Currency related split payments apparatus for a mining aspect of rewarded distributions to poverty, animal, wildlife and environment beneficiaries.

Examples described herein provide a method for overspeed protection of a motor of a gate crossing mechanism. The method includes monitoring, by an overspeed protection circuit, a voltage across a first Zener diode and a second Zener diode. An anode of the first Zener diode is connected to an anode of the second Zener diode. The method further includes, responsive to determining that a Zener voltage threshold is exceeded, allowing a current to flow into a gate pin of a triac. The triac controls the motor of the gate crossing mechanism.

A motor fault detection system is based on coupling injection of high-frequency signal. An input end of the motor is connected with the high-frequency detection signal source circuit through the coupling circuit to inject a high-frequency detection signal into the motor winding; an input end of the high-frequency detection signal source circuit is connected with an output end of the controller to control the output of the high-frequency detection signal; an output end of the response signal processing circuit is connected with an input end of the controller to send the received voltage or current response signal to the controller; and the controller judges whether the motor has a fault and the degree of the fault by analyzing the response signal after applying an excitation.
