Description

 ELECTRONIC CONTROL SYSTEM OF ELECTROCHEMICAL REACTORS FOR GAS PRODUCTION

OXY HYDROGEN

FIELD OF THE INVENTION

The present invention falls in the field of the production of alternative energies or clean energies, such as the production and generation of oxyhydrogen gas that is used as an alternative fuel, produced through electrochemical reactors (they produce a mixture of hydrogen gas and oxygen in a 2 to 1 ratio from water and electricity). More specifically it refers to a novel electronic control system of electrochemical reactors for the production of oxyhydrogen gas that will be used as fuel.

BACKGROUND OF THE INVENTION

The most used energy in the world is fossil energy. If all that is at stake is considered, it is of the utmost importance to measure accurately the fossil fuel reserves of the planet. The "identified reserves" and the "probable reserves", which could be discovered with future technologies, are distinguished. According to calculations, the planet can supply energy for 40 more years (if only oil is used) and more than 200 (if coal is still used). Fossil fuels can be used in solid form (coal), liquid (petroleum) or gas (natural gas). They are accumulations of living beings that lived millions of years ago and have fossilized forming coal or hydrocarbons. In the case of coal, these are forests in swampy areas, and in the case of oil and natural gas from large masses of marine plankton accumulated at the bottom of the sea. In both cases, the organic matter was partially decomposed due to lack of oxygen and the action of temperature, pressure and certain bacteria so that molecules with high energy bonds were stored.

Renewable energies have been an important part of the energy used by humans since ancient times, especially solar, wind and hydraulic. With the invention of the steam engine by James Watt, these forms of exploitation are being abandoned, because they are considered unstable in time and capricious and thermal and electric motors are increasingly used, at a time when the still relatively low consumption , there was no need to foresee a depletion of sources, or other environmental problems that later arose.

By the 1970s, renewable energy was considered an alternative to traditional energy, both because of its guaranteed present and future availability (unlike fossil fuels that require thousands of years to form) and because of its lower environmental impact on the case of energies clean, and for this reason they were called alternative energies. Currently many of these energies are a reality.

This is where the present invention falls, which derives from research, development, manufacture, promotion and use of oxyhydrogen gas generators, also called Brown gas in honor of its Yull Brown discoverer, used as fuel and that can be used in any application where replacement of this fuel is feasible, in exchange for fossil fuels.

In different countries there are many researchers trying to develop hydrogen generating models with characteristics of good efficiency and high gas production, there are different designs, shapes, materials, construction parameters, electrolyte concentrations and chemicals used as electrolyte, and with what Constant struggle is to maintain the efficiency of the equipment. However, these devices do not include electronic gas production control systems, or have poor systems that affect the production efficiency of oxyhydrogen gas.

An investigation was conducted to determine the state of the art and the following documents were found:

US Patent 6338786 B1 of Steven J. Thorpe et. to the. filed on July 16, 1999, which refers to a method Improved separation of hydrogen gas produced with a first aqueous electrolytic solution of a water electrolyzer for the production of said hydrogen and said oxygen gas entrained with a second aqueous electrolytic solution. The production of hydrogen gas comprises two phases in a first discharge of electrolyte solution flow; producing a second two phase flow discharge of said oxygen gas in said second solution; feeding said first discharge to a separation chamber having a first part defining a hydrogen chamber to effect the separation of said hydrogen gas from said first discharge; feeding said second discharge to a separation chamber having a second portion defining an oxygen chamber to effect the separation of said oxygen gas from the second discharge; collect hydrogen gas from the hydrogen chamber; collect the oxygen gas from the oxygen chamber; collect the gas from the first discharge; collect the gas from the second discharge. The improvement in which at least one of said first discharge is discharged into said hydrogen chamber and said discharge is discharged into said oxygen chamber.

It is detected that this device has the disadvantage that two electrolyte solution flows are required, one first to obtain hydrogen and a second to obtain oxygen.

Another disadvantage detected is that the apparatus requires two chambers, a first separation chamber having a part that defines a hydrogen chamber; a second chamber of separation that has a part that defines an oxygen chamber and means to collect the gases.

Another disadvantage detected is that it does not mention the optimal type of electrolyte for the generation of high quality oxyhydrogen.

There is no mention of the use of an electronic control system that allows to regulate the operating conditions, nor the volumes of gas production.

US Patent 20120103796 A1 of Kenji Taruya et. to the. filed on September 22, 2011, which refers to a water electrolysis system that includes a high pressure water electrolysis apparatus and a gas-liquid separation device. The gas-liquid separation device includes a blocking member that includes a gas-liquid separation opening and a water level detection opening. The gas-liquid separation opening and the water level detection opening extend vertically and include respective lower portions that communicate a single piece with a discharge tube.

The discharge tube is arranged in a lower side portion of the block element. The water level detection opening includes an upper part and an upper water level detection section. The block member further includes an inlet port in which hydrogen is introduced from the high pressure water electrolysis device. The entrance hole is disposed in an upper side portion of the block element.

The inlet hole is located above the upper water level detection section of the water level detection opening.

It is detected that this device has the disadvantage that it does not reveal the composition of the electrolyte. Another disadvantage detected is that the water electrolysis device in the production of hydrogen gas uses a solid polymer electrolyte membrane (ion exchange membrane), instead of a liquid electrolyte, to decompose the water. Another disadvantage detected is that the water electrolysis system comprises a substantially cylindrical glass body, which can be easily broken due to the type of material.

Another disadvantage detected is that the device has a metal block member having an opening that accommodates the glass body, the type of metal is highly corrosive and maintenance is required constantly.

There is no mention of the use of an electronic control system that allows to regulate the operating conditions, nor the volumes of gas production.

The international publication WO 2012056751 A1 by Toshiaki Suzuki was also found regarding the application filed on 08 April 2011, which refers to a water electrolysis device that has excellent water electrolysis treatment capacity without increasing the size of the device or incurring greater equipment cost, and to provide a fuel supply apparatus Economical, safe, and environmentally friendly by using the water electrolysis device, this water electrolysis device is configured to electrolyze water in an electrolytic bath in which a plurality of electrode plates is housed, producing a mixture of hydrogen and oxygen gas, and discharges the mixture of generated gas, in which the temperature of an electrolyte solution is detected by temperature of the electrolyte solution and the number of electrode plates that contribute to electrolysis between the plurality of electrode plates it increases or decreases depending on the temperature of the electrolyte solution detected by the temp Erature of the electrolyte solution.

It is detected that said device has a helical spring of elastic member that pushes the electrode plates that are at the inner ends of the plurality of electrodes, this causes said plates to be manufactured of a greater thickness so that they do not break, This push causes the plates to be constantly checked to see their functionality.

Another disadvantage detected is that in the cooling system it consists of cooling pipe and a cooling fan at both ends of the cooling pipe, this does more It takes time and therefore less efficient to cool the device, since it is cooled by air.

There is no mention of the use of an electronic control system that allows to regulate the operating conditions, nor the volumes of gas production.

Also found was US Patent 8168047 B1 by Jerry Smith, Littleton filed on October 29, 2008, which refers to an H2O electrolysis cell mounted on a hydrogen creation vehicle. Hydrogen is mixed with the fuel supply of a vehicle for greater fuel economy. The electrolysis cell includes a cell housing for water retention. A plurality of positive electrode plates mounted within the cell housing and is attached to a positive pole mounted on the top of the cell housing. The positive pole is adapted for connection to a vehicle's power source. A plurality of negative electrode plates are mounted inside the housing and indexed in a separation relationship between each of the positive electrode plates. Negative electrode plates are associated with a negative pole mounted on the top of the cell housing. The negative pole is also adapted for connection to a vehicle's power source. The negative electrode plates are attached to a moving plate rod mounted inside the cell housing. One end of the mobile bar is adapted for attachment to a joint assembly connected to the fuel system of a vehicle. As the vehicle accelerates, the rod moves the negative plates towards the positive plates, thus increasing the amount of water electrolysis in the cell housing and therefore increasing the amount of hydrogen generated therein. Hydrogen is discharged to a hydrogen fuel port on top of the cell housing for the fuel system.

This device has the disadvantage that a vehicle requires to be driven and cause a rotation that moves a bar that in turn moves the negative plates towards the positive plates, thus increasing the amount of water electrolysis in the cell housing and therefore the increase in the amount of hydrogen generated.

Another disadvantage detected is that as a rotary movement is required, constant supervision is required to perform preventive and corrective maintenance of the bar and the rotating plates, because they can suffer frequent deterioration in short times. Another disadvantage detected is that it is designed exclusively to be coupled to internal combustion vehicles in order to reduce their fuel consumption.

There is no mention of the use of an electronic control system that allows to regulate the operating conditions, nor the volumes of gas production. The publication of the international application WO 2012049689 A2 of Thakore Pratik filed on October 10, 2011 was also found, which proposes a controller for the regulation of the production of water detonating gas with the arrangement of electrodes with asymmetrically ventilated electrolyser modules . The electrolyser has electrodes with asymmetric or non-linear arrangement of water inlet ventilation for water flow at the lower level. The water intake vents are of a smaller proportion than the gas outlet diffusers. The gas outlet diffusers with an asymmetric or non-linear arrangement for the flow of gas at the upper level of the electrodes in the electrolysing cell unit arranged alternately in bipolar tube-shaped electrodes.

The asymmetric ventilation holes are arranged at the maximum distance between the (Gas Outlet Vent) GOV and the water inlet vent (WRV) in the same electrode tube or plate shape to prevent current leakage between the electrodes . The asymmetric arrangement does not allow the flow of water between the electrode plate in a single line and the non-linear asymmetric arrangement does not allow the flow of gas in a single line. Therefore increases overall efficiency and reduces heat losses. This eliminates the need for the temperature control system. The electrolyser is in modular form of the series and the combination in parallel with the electronic controller for the power supply with switching frequency of the power transistors to regulate the gas output to adapt to various Applications.

It is detected that this device has the disadvantage that it can only be powered by direct current so that it can perform its function.

There is no mention of the use of an electronic multi-variable integral control system that allows to regulate the operating conditions, nor the volumes of gas production.

The publication of patent application WO 2011158153 (A1), by Fong Sze Chun and Lam Chi Long Daniel of June 15, 2011, which basically consists of a system designed to make combustion of engines more efficient through four stages, the first consists of the acquisition of the data of the internal combustion engine of injection through at least one sensor, such as MAP / MAF / Oxygen / TPS, the second part transforms this data to finally in the third stage take control actions by modifying the injection of fuel into the engine and the injection of oxyhydrogen from a generating unit with stainless steel and electrolyte electrodes, where its temperature, pressure and liquid level are monitored and regulated. The information is transmitted to the user through indicators on the status of the system. On the other hand, the system is connected to a kind of computer or additional electronic system for the visualization of the parameters of the oxygen generator and the engine sensors and that the installer can manipulate the configuration of the control unit and the generator to establish the flow of oxyhydrogen.

The system sends a maintenance notice for gas leakage (detected by a sensor), because the cooling system does not work (consisting of a liquid recirculation pump and fans for a thermal radiator), due to out of range pressure levels or that the filling system does not work properly. Finally, this invention contemplates a method (algorithm) for optimizing combustion by modifying fuel injections based on the parameters of the engine sensors.

The electronic control system is complex and involves multiple components that must interact with the injection systems of the engine of the vehicle that is fed with the gas produced. Its installation and operation is complex.

It is important to note that this invention contemplates an invasive method for the engine, since the original engine injectors must be modified to enter the oxyhydrogen.

Unlike the aforementioned document, the present invention is not an invasive method with motors, since it does not require altering the motor in any fundamental aspect, and has many other applications thanks to its programmable electronic control.

In addition, the original signals of the sensors and the Combustion engine ECU injectors for system operation, the invention generates a much larger volume of oxyhydrogen gas. Given the need for a programmable electronic control system of electrochemical reactors for the production of highly efficient oxyhydrogen gas, with excellent performance, which allows the control of the production of high quality gas, it was that the present invention was developed, that achieves a large gas production of up to 12 LPM of good quality, that is, with a low water vapor content, this due to electronic control system that allows the production process to be efficient, control process variables and manages to keep operating to the reactor in optimal working parameters.

Another objective of the present invention is to offer a system electronic control of electrochemical reactors for the production of oxyhydrogen gas, which also allows to reduce operating costs, also reducing the consumption of traditional fossil fuels, and even in some applications replace them to 100%.

Another objective of the present invention is to optimize internal combustion in engines that use fossil fuels.

Another objective of the invention is to adapt the electronic electrochemical reactor control system for the production of oxyhydrogen gas to engines using any type of fossil fuel, converting it into a hybrid using oxyhydrogen, without making modifications to established systems. Another objective of the present invention is to offer an electronic electrochemical reactor control system for the production of oxyhydrogen gas that guarantees the production of a large flow of hydrogen gas at high efficiency, guaranteeing reliability and safety in the operation of the system.

And all those qualities and objectives that will become apparent when making a general and detailed description of the present invention supported by the illustrated modalities.

DETAILED DESCRIPTION OF THE INVENTION The characteristic details of the electronic control system of electrochemical reactors for the production of oxyhydrogen gas are clearly shown in the following description and in the accompanying illustrative drawings, serving the same reference signs to indicate the same parts .

Referring to Figure 1, the electronic control system of electrochemical reactors for gas production Oxyhydrogen in accordance with the present invention, consists in the association of a central control module 1 that performs the sensor readings, stores the configuration parameters, performs all the information processing and executes the control actions, and which It is interconnected with a power module 2 from where it is powered by electric current and to which it controls and monitors the supply current and voltage by at least one current sensor 3 and at least one voltage sensor 4 from the supply source 5 and the temperature of said power module is controlled by at least one temperature sensor 6 that measures the temperature of the power transistors that regulate the power supply of at least one reactor producing oxyhydrogen gas 7, thus avoiding overheating; said power module 2 regulates the electrical consumption of the oxyhydrogen gas production reactor 7, the generation of the gas and therefore the system pressure, and the temperature of the electrolyte, all by means of a PWM signal that comes from the central control module 1 , which also controls in said oxyhydrogen gas production reactor 7 the electrolyte level by a level 8 sensor, the electrolyte temperature by a temperature sensor 9 and the pressure by a pressure sensor 10.

Said central control module 1 being further connected to a user interface module 11 and a display interface module 12, in which a display screen 13 with brightness control 14 is connected which allows the display of sensor readings in real time and allows programming of the system through certain menus as it integrates the reception system for a remote control 15 of the user interface module 11; In addition, a voice reproduction system 16 with horn 17 is connected to allow the user to give important messages about the equipment. These messages include errors or special conditions that may occur during the operation of the reactor, for example, if it requires any service or maintenance. , the water level is low, etc.

Said central control module 1 comprises a removable memory system 18 for storing information as operating parameters and reporting of the operation history (measurements and reactor status); and a general switch 19 with a power signal 20 that allows the system to be turned off manually.

Said oxyhydrogen generating reactor 7 being connected to a pair of electrolyte filter safety systems 21, 22, and to a water and moisture filter 23 in the outlet duct 24 of the produced oxyhydrogen gas which leads it towards the combustion equipment ( not shown), where a duct integrity detector 25 controlled by said central control module 1 is connected. When the system is applied to an internal combustion vehicle, the central control module 1 is connected to a tachometer 26 which to its Once connected to an internal combustion engine component (not shown) that provides the information, which can be the Engine alternator or ECU (Engine Control Unit) of the vehicle (not shown).

Said oxyhydrogen generating reactor 7 is fed with water from a water supply source 27.

With reference to Figure 2, the symbology used in the subsequent figures of the flowcharts of the operation of the control unit of the electronic control system of electrochemical reactors for the production of oxyhydrogen gas is provided. The reference numbers for each symbol and their meaning are listed below: 28: start or end, 29: process, a series of steps are associated, 30: alternative process, can occur at any time with respect to the normal execution of the system, 31: subroutine, direct action, 32: decision, 33: display warning, 34: input signal, 35: input data (s), 36: event timeout by performing specific actions or time delay. Although in the subsequent figures the symbolism illustrated, enunciated and referenced in figure 2 are used; Other consecutive numerical references of each step will be used in each flowchart of subsequent figures to avoid confusion and duplication of reference numbers. It will be understood then that the symbol used will take actions according to the meaning of the form as described in Figure 2; but it will have a consecutive numbering for references the stages and the precise actions that are executed in these. With reference to Figure 3, this flowchart is where the operation of the system begins by receiving an ignition signal 94 that energizes the OCU (Oxyhydrogen Control Unit) and in turn generates another internal signal that allows it to itself it stays on even when the ignition signal is no longer present (start turns on electronic control 95), the latter because when the reactor is turned off when the ignition signal is turned off, the OCU still performs internal data storage processes and Once it is finished, you can proceed to completely shut down the system, including, this ignition signal will be constant as long as it is necessary to keep the Oxyhydrogen Reactor active, and it can come from different sources such as: in the case of application in engines of internal combustion of the engine oil pressure bulb, the general ignition switch of the vehicle, or the signal of the engine revolutions in where a certain threshold of RPM (Revolutions Per Minute) is detected that indicates that the engine is running; in other applications in general the signal may come from a PLC (Programmable Logic Controller) of an industrial system, for example as a boiler, or simply from a switch.

Next, the system initialization process 96 shown in Figure 4 is executed.

With reference to figure 4 which shows a flow diagram of the system initialization process, illustrating with numeral 37 the realization of a subroutine the internal configurations corresponding to the control module, these are: configure the processor clock frequency, configure the ports that will be input or output for the connection with the peripherals, configuration of the interruptions that can occur to attend the events that happen with some sensors and peripherals such as changes of state in a signal, also configures the communication port to transmit data to the user interface module which is the one that will display system information on the screen and will reproduce operation problems by voice of the equipment, on the other hand the analog channels are configured to make readings of the information that the sensors transmit in the form of voltage (current, pressure, temperature, RPM, voltage) by means of an ADC (Analog to Digital Converter), it is configured the internal stage of generating the PWM (Pulse Width Modulation) signal that will be in connected to the power module of the system, this PWM signal allows to regulate the energy consumption of the reactor, the gas flow produced by the reactor, the working temperatures of the equipment so that they do not exceed and the pressure of the gas generated, the above is achieved by varying the "duty cycle" or gain of the period of the signal, that is, the time it remains on and off in relation to the period of the signal (Figure 5); on the other hand initializes the temporary hour meter in zeros, this hour meter allows to time the system operating times of continuous hours of use, that is, for every time it is turned on until the system is turned off.

In the following subroutine 38 the "error flag" is reset, the which will be activated when an error occurs in the system (see table I, Error messages and error codes) and thus notify the user; the "first time" flag is also activated which allows the system to identify if it is the first iteration of the system status storage thread when an error is present, this with the objective of storing the error log in Flash memory that have occurred, especially in this initialization and startup process; the "no send" flag is also activated, which is associated with the subprocess of identifying changes in the system status and sending the update to the user interface module for display, if this flag is activated, as in this case, it is inhibited This update thread and the objective of activating it during this process is because readings of the system sensors will be made and at this point it is not desired that the updates be sent and that it will delay the startup.

Table I.- List of possible system error messages and their error code.

 Then, with the subroutine 39, the initialization of the counter 1 is executed in zero since this counter will be used to count minutes, so that when it reaches five the "5 minute timer" flag will be activated that will be used in the process PWM regulation to verify the status of the reactor electrolyte temperature.

In the following subroutine 40 initializes the PWM signal at 0%, that is, the reactor completely shut down (without electrical power). In subroutine 41, the flash memory (non-volatile) of the control module storage is initialized, in this memory all the system configuration parameters and a record or report of the system status are stored in a table format that is stored every determined time (timer 'Storage'), if the initialization of the memory fails, the error returns with priority level 1 illustrated with numeral 42, later it will be explained how the errors in the central program are treated. Next with numeral 43, verify the connection with the If the user interface module does not exist, the process is exited by returning the error with priority level 2 illustrated with numeral 44, otherwise it continues with the rest of the system initialization.

In this next subroutine 45 the user interface module is initialized, that is, its processor, the display screen, its memory system, the audio reproduction system for the messages, its communication port with the control module and the remote control sensor to receive the system programming and configuration commands, if the initialization of any of these parts fails, the error with priority level 1 illustrated with the same numeral 42 returns, otherwise the process flow continues.

In this following subroutine 46, the "system file ¹¹ of the Flash memory containing all the configuration parameters (table II) for the operation of the equipment and saves them in the RAM (Random Access Memory, volatile) is read for Its quick access and use.

With the numeral 47 the configuration parameters described in the following table II are entered.

 Table II.- System configuration parameters.

 subroutine 48 below, the ranges of some configuration parameters are validated so that they are within the physical limits of operation of the reactor itself, of the sensors or of the electronic system (Table III), these may be out of range (numeral 49) due, for example, to an error in reading the file, if there is any value out of range, a default value is set, see subroutine 50 (Table IV).

Table III.- Valid ranges of some system configuration parameters.

Table IV.- Default values of some system configuration parameters.

The parameters of Tables III and IV can be changed according to the evaluation of the type of application, and the materials used in the construction of the reactor and the power stage, serve as a reference example for a better compression of the system operation .

Subsequently in subroutine 51 it is stored in a register additional (maximum programmed current 2) the maximum programmed current (Imax), this because the value of the maximum programmed current register 2 will be altered according to the PWM regulation algorithm and it is necessary to recover the original programmed value at a certain point in the process which will be explained in detail later.

Now in subroutine 52 the gas production constant (K) that represents the milliliters of oxyhydrogen per second that are produced for each Amper consumed by the reactor is calculated, this is done with the configuration parameter 'Efficiency (LPM vs Amps ) "according to the formula presented in the flowchart.

Consequently in subroutine 53 a conversion factor (F) is calculated to calculate the water consumption (mi) based on the constant K and the current consumed by the reactor, starting from the fact that 1000 mL of water produces approximately 1750 L of gas . Now in subroutine 54, the KF product is stored in RAM to simplify these calculations in the PWM regulation process. In subroutine 55, according to the configuration of the system read from the memory, the flags of the sensors that are going to be in operation are enabled and disabled of those that are not going to work because the particular application does not require it and It may not be connected or even not installed on the system.

At this point it enters another process of "sensor reading" 56 that it is illustrated in detail in figure 6 and for this we refer now to said figure 6, where in subroutine 57 the first sensor that is verified is the tachometer, it is evaluated if it is enabled according to the configuration of the "system file ", if it is not enabled, the following sensor would be read, if it is enabled it performs a reading of the RPM and saves the data in RAM illustrated with subroutine 58, now a current sensor reading that is illustrated with subroutine 59, in this case it is not a sensor that can be disabled so this step is always executed, based on the value of the sensor signal (before being converted into units of Amperes); with numeral 60, a decision is made and it is verified whether it is disconnected or not, if it is, an error is returned with priority level 2 see numeral 44, otherwise the operating range is validated according to table III; in the decision making illustrated with numeral 61, it is evaluated if it is out of range, if it is again, an error returns with priority level 2 see numeral 44, otherwise it proceeds to process 62 that performs the conversion of the value obtained in amperes , save the data in RAM and in the decision making illustrated with numeral 63 verify the following sensor that is the pressure one, performing the same protocol as with the current one: it obtains the value of the signal equivalent to the pressure (see numeral 64), check if the sensor is connected (numeral. 60, if connected it returns to a priority error 2, 44), if not, it is validated if it is within the functionality range (table III) numeral 61 (if it is in range it returns to error of priority 2, 44; if it does not obtain the pressure value and save it in RAM see numeral 65. Then continue with the determination of the enablement of the power temperature sensor, see numeral 66, if enabled it obtains the value e the signal equivalent to the temperature of the process stage, see numeral 67 and continues the same steps illustrated with numerals 60 for detection be the respective sensors; if it detects them it returns to the error of priority 2, numeral 44 and if it does not determine if it is within or outside the range 61, if it is returned to the error of priority 2, numeral 44; if not, it converts the value of the signal into units of temperature and saves the data in RAM, numeral 68. Subsequently, it obtains the value of the signal equivalent to the temperature of the reactor electrolyte, numeral 69 and evaluates the same decisions indicated with the numerals 44, 60, 61 and 68.

Subsequently, only the working voltage range of the power supply is read and validated depending on the voltage selector and is stored in RAM, see numeral 70, so that if it is set to 160 VDC the voltage must be between # Cells x 2 Volts and # Cells x 2.4 Volts, if the selector is in 12/24 VDC position, it is checked if it falls within the range <or> = at 18 Volts, see numeral 71, if it is in the lower range verify that the voltage is between 12 and 14.5 Volts, if it is in the upper range verify that it is between 24 and 29 Volts, if it is out of range the error with priority level 2, numeral 44 returns, otherwise the data is saved in RAM, finally the reactor liquid level is verified and the information (see numeral 72) of whether it is low or not is stored in RAM and returns (numeral 73) to the routine where this process was called, which according to this particular description, the numeral initialization process 56 of Figure 4 returns to finish.

Returning to Figure 4, if a priority error 2, numeral 44 due to connection problems or out of range, was returned in the reading process of sensors 56, now this initialization process in turn returns the same error in such a way that the indication should go to the central program and proceed according to the diagram (later on, the behavior of the central program will continue to be detailed).

Returning again to said figure 4 and continuing with the initialization, what follows is to perform a functional test to the power module, to do this the PWM signal is activated with a gain of 3%, see numeral 74, for a short period of time. time and a current sensor reading is made to verify that the power module is providing power to the reactor, see numeral 75, if there is no current consumption reading an error with priority level 1, numeral 42, of otherwise, the system status update that includes the sensor readings is sent to the user interface module, see numeral 76, by the process illustrated in figure 7. In said figure 7, the process is executed where send the data stored in RAM corresponding to: The user interface module 11 (see figure 1) via the communication port: voltage 77, current 78, reactor temperature 79, temperature of the power module 80, the electrical power consumed by calculating it by the formula P = VI (product of the voltage by the current) 81, the temporary hourometers 82 and global 83, the pressure of the oxyhydrogen 84, the percentage "Duty cycle" of the PWM 85, the RPM of the engine 86, the status of the liquid level in the reactor 87 and finally that of the pipelines that carry the hydrogen 88 (which are Integral), fits mention that if any sensor is disabled, its reading will not be transmitted. Later he returns (numeral 89 to the process of figure 4)

Returning to figure 4, to conclude with the initialization process of the system, with the numeral 90 the subroutine is shown where the 'Flag level' is loaded with zero, this flag allows that when the reactor liquid level is evaluated In the PWM Regulation process and if it is detected low for the first time, the corresponding warning that it needs to be filled with water is sent; the manual mode is also deactivated.If it is activated, it is used to set the "Duty cycle by means of the remote control. "of the PWM manually, using it from 0 to 100%, resets the flags of:" Update 'which indicates when the timer has reached the set time (table II) to update the sensor readings, send the status and regulate the PWM, "5 minutes" that is activated every 5 minutes (used in the PWM regulation process), and those of "Regulating temperature / temp. Power / pressure" that indicate to the system that a control is being carried out l about those parameters. In the following subroutine 91, two timers are configured with a time base of 1 second and 1 minute, which will be used to generate the interruptions of the "Update" and "Storage" timers, as well as of the minute timers for the hour meters. and 5 minutes for other functions of the "PWM Regulation" process, and your counting starts here.

To conclude this process of initiation with numeral 92, the subroutine with which the "No sent" flag that had been activated is deactivated, this is shown so that the update of the system status is sent to the interface module if it occurs A change in the system. Now return (see numeral 93) to the central program of figure 3.

 Returning again to figure 3, where the treatment of the errors that the process of Initiating the system 96 returns, which other processes within the initialization could also have generated, will be made explicit:

First, the priority level of the error illustrated with numeral 97 is evaluated, if it is 1 or 2, a priority error 1, numeral 98 means that it is Critical, the system cannot continue in operation and the error will not change state depending on of time since it can be a fault for example of some component; if it is of priority 2, numeral 99, it means that it may not be so critical, and the error can change to a state without error, so it expects the change but stops the operation of the system, therefore if it is level 1, Numeral 98 keeps the reactor off without produce oxyhydrogen, sends the corresponding error indication for review and activates the error flag to stop timers and stopwatches without enabling their flags, at this point the system is inactive reporting only the error, if the power signal it turns off, when it is turned on again it will try to initialize the system and if the error was corrected then it will continue with the normal operation of the equipment; on the other hand if the error is level 2, numeral 99, it will verify if it is an error related to the communication connection with the interface module, if it is, it will activate an audible alarm that is illustrated with numeral 100 to indicate The error, if the error is not related to the communication, then sends the error indication to the interface module, marked with numeral 101, and in both previous cases it will proceed to: indicated with numeral 102, save the error code in the RAM, activate the error flag and monitor the error until there is a change of state in such a way that the error condition no longer exists, if it detects that there is no error, deactivate the error flag 103 and re-execute the process Initialization 96.

Once the initialization process 96 is executed satisfactorily, it enters the PWM Regulation 104 process whose steps are illustrated in Figure 8, which is one of the most important processes in the operation of the system since it is the process it takes in It counts the status of the system to regulate the power stage through the PWM signal, which finally provides power to the reactor, this in order to comply with the configuration / programming established for the system to operate according to certain parameters (current, temperatures, pressure, level, voltage, ... etc.).

With reference to Figure 8, the process begins with verification 105 if the "Duty cycle" of the PWM is greater than 0%, that is, if the reactor is on, if it is 0% it will continue with the program normally, as On the contrary, it will verify that the current is greater than 0 amperes, see numeral 106, that is, that there is an electrical consumption since if there is not it will indicate that there is a problem with the power module since it is not supplying power to the reactor and this will cause a error of priority level 1 and will exit this process, which is illustrated by numeral 107; If it detects that there is electricity consumption then it continues with the execution of the process. Then check the status of liquid level in subroutine 108, if the level is low then check the level flag (configured in the initialization process) see numeral 109, if this flag is at "0" will proceed to send the warning of low level in subroutine 110, since this flag indicates that it is the first cycle in which this condition is being detected, subsequently illustrated with numbers 111, 112, 113, 114 and 115 the number of cells that the reactor has is verified (<12, <24, <36, <48, <60 or> 60) and based on this information and according to the design of the oxygen generator gas reactor, the "remaining milliliters" (156 mi, 312 mi, 468 mi, 624 mi, 780 mi, 1000 mi) indicated with the numerals 116, 117, 118, 119, 120 and 121 in this variable, which corresponds to the remaining water so that the reactor reaches the minimum allowed level of liquid, this with the end to leave a margin of operation of the system even when the liquid is low; Now with numeral 122, set the level flag to "Γ, so that the next time the OCU enters this process and detects a low level, it no longer sends the warning or establishes the remaining milliliters of water, but rather by using a formula in the subroutine 123 subtracts the water that is consumed according to the current consumed by the reactor, the KF factor (described in the initialization process) and the "Efficiency" configuration, this allows verifying that when the variable "milliliters remaining "reaches zero (see numeral 124) means that the reactor reached the minimum level of water allowed and the system could be turned off by returning a" no water "error with priority level 2 shown with numeral 44, later described as errors in the central program are treated after the system initialization process, that is, when the equipment is already operating; if there is still water remaining the reactor operates normally following the flow of the diag branch In the event that the level of the reactor determined by subroutine 125 is fine, a zero is simply assigned to the level flag so that when it reaches a level below this flag it allows the low level warning to be sent to the system user.

The next step with numeral 126 of this process is to verify the voltage selector, so that it is known if the system is operating with low voltage (12 or 24 volt systems) or with high voltage (systems up to 160 volts ). If the system operates at low voltage it is first established if the voltage is greater than or less than 18 volts (numeral 127), which is the midpoint between 12 and 24 volt systems, if it is smaller it is known to be a 12 volt system, and if it is greater or equal it is known to be 24 volts (numeral 128), if it is greater than or equal to 129 volts (numeral 129) ; Now it is verified that if it is a 12-volt system, the voltage is between 12 and 14.5 volts, numerals 130 and 131, and if it is a 24-volt system, it is verified that it is in a range of 24 to 29 volts, if in any of the two cases the voltage exceeds the upper limit returns a "high voltage" error of priority 2, 44; if it is below the lower limit, a "low voltage" error of priority level 2, 44 also returns. On the contrary, if it is a high voltage system, the upper and lower limits are evaluated according to the number of reactor cells, parameter that was configured in the system file, setting the upper limit in #Cells x 2.4 volts numeral 132, and the lower limit in #Cells x 2 volts, numeral 133, and in any case out of range an error with level would also return Priority 2, number 44.

If the voltage is in a correct range, then it is evaluated if the system is in manual or automatic mode with the corresponding flag (see numeral 134), if it is in manual mode (activated by programming) the system in its routine 135 allows the PWM signal to be modified instantaneously through the remote control, in this way it would be "disabled" and the operation returns (numeral 136) the rest of the follow-up of this process, which has to do with the PWM setting depending on the sensors. If "Manual mode" is disabled, then continue with the process flow. Next, it is checked if the tachometer is enabled (numeral 137), if it is checked then in which of the four ranges are the engine RPM, if the engine is idling, that is, in the range 1 of RPM (numeral 138), activating the flag without sending with subroutine 139, then the OCU puts the PWM at 0% (numeral 140), turning off the reactor energy and proceeds to perform the sensor reading process (numeral 141) to update the sensor measurements and send to the interface module the new status of the system shown with numeral 142 to deactivate the flag without sending illustrated with numeral 143; ending this process of PWM regulation. If an error was found in the reading of the sensors, the error with priority level 2, 44 is returned. It should be mentioned that it is of great importance that the reactor be turned off when the application is in internal combustion engines and the engine is in Idle, this because it does not justify the injection of oxyhydrogen and the energy consumption that involves its production when no work is being done, since the efficiency in the burning of fuel is obtained in the changes of acceleration at the time of injecting more or Less fossil fuel

If the motor is in the second RPM range (numeral 144), proceed by subroutine 145 to assign that the maximum current with which the reactor will operate ("current B") will be A% of the maximum current programmed ( Maximum programmed current 2 of the initialization process), if it is in the third RPM range, numeral 146, will then be B%, numeral 147 and if it is in the fourth range, numeral 148, it will be 100% of the maximum current that was programmed, numeral 149. It should be mentioned that if the tachometer is disabled then the current will be programmed as in the fourth range, that is, 100% of the maximum current that was programmed.

Now at this point 150 of the process the flag of the 'Timer 5 Minutes' is verified, to know if that time has elapsed, if the flag is active indicating it, then by subroutine 151 resets the flag and verifies if it is already in the process of regulation of the reactor temperature (electrolyte) numeral 152, if it is not yet regulating the temperature then check if the reactor temperature (electrolyte) is lower than the programmed maximum minus 1 degree centigrade (numeral 153), if the temperature is below, it will continue to the next stage of the process, if the temperature is equal or higher then by means of subroutine 154 it activates the "temperature regulation" flag, and now a new verification is made of whether the temperature is lower than the programmed maximum minus 5 degrees Celsius (numeral 155), this evaluation will make sense in subsequent verifications to this first one, since now the tempera regulation flag is activated ture through subroutine 154 and the program will immediately go to this evaluation that will let you know if the temperature has decreased, if it has not decreased, it will reduce the programmed maximum current 2 (numeral 156) by a percentage so that it decreases every 5 minutes the consumption of reactor energy, which will cause the electrolyte 8numeral 157 to cool down), if for some reason, this current that decreases reaches zero, then it would continue with the rest of the algorithm execution; if the temperature of the electrolyte decreased by 5 ° C with respect to the maximum programmed temperature then it would proceed to disable the temperature regulation flag (numeral 158) and resetting the maximum programmed current 2 with the current programmed in the system originally (initialization) numeral 159.

Now we proceed to verify if there is any other active regulation flag corresponding to the temperature of the power stage or pressure (numeral 160), if the sensors are enabled, if they are not, it will be taken as a negative condition (numeral 161), that is to say, that there are no active flags, and if this is the case, the "Duty cycle" of the PWM will be increased by 1%, each certain milliseconds, for example, can be 100 milliseconds to increase 10 times per second, 0% to 100% in 10 seconds, until the reading of the reactor current is greater than or equal to "current_B", or that the readings of the temperature of the power stage or the pressure have been after the maximum allowed range (if the last two are enabled), the previous procedure indicates that the system is designed to try to maintain the maximum current programmed in the system, but taking into account the state of the sensors and that the reactor work within the allowed ranges of operation. If the evaluation of the regulation flags detects that It is in a regulation cycle, or if in the process of increasing the "Duty cycle" it is detected that the PWM has reached 100%, it goes directly to the next stage which consists in ensuring that the current is lower than the established current ( "Corr¡ente_B"), because the regulation flags indicate that the "Duty cycle" should not be increased but instead that it is being reduced to make the corresponding regulation.

In this next stage, the "Duty cycle" of the PWM is reduced by 1%, each certain milliseconds, for example, it can be 50 milliseconds to decrease 20 times per second, 100% to 0% in 5 seconds, until the reactor current reading is less than the "Current_B"; on the other hand, if the "Current_B" is zero amperes, the conditional cycle is exited by setting the PWM to 0%. (See numerals 162 to 172 and 44).

Then it is validated if the temperature sensor of the power stage is enabled (numeral 173), if it is not checked, check the pressure sensor see numeral 174 (the routine will be detailed below), on the contrary if it is enabled it makes another reading of this temperature (numeral 175), apart from the one that was made in the initialization, in order to update the data since during the previous process the temperature value could have been modified, it is verified if It is regulating the temperature of the module (numeral 176), if it is not in the process of regulation it is verified if the temperature is higher than the maximum that was programmed (numeral 177), if it has not exceeded this continuous temperature at check the next sensor (pressure) numeral 174, but if it is equal to or greater than the programmed one then activate the regulation flag (numeral 178) and check if the temperature is lower than the maximum programmed minus 5 ° C (numeral 179), this The last conditional is evaluated since once the regulation flag is activated, the evaluation will be done in each iteration to ensure that the temperature decreases, if the temperature decreases until the condition is met, reset the temperature regulation flag of this stage of power (numeral 180) and continues to evaluate the next sensor (pressure) numeral 174; but as long as the temperature does not decrease, a decrease of the "Duty cycle" of the PWM (numeral 181) will be made in each iteration or regulation cycle of the PWM, if for some reason the PWM reaches 0% (numeral 182) it will go directly to the evaluation of pressure sensor 174.

First it is verified if the pressure sensor is enabled (numeral 174), if it is not, the PWM regulation process will end, activate the flag without sending, numeral 183 making a last reading of all the sensors (numeral 184) and if are out of range or offline, the error is returned to priority level 2 (numeral 44) and updating the system status by sending the system status to the interface module per communication port (see numeral 185) and with subroutine 186 deactivated flag without sending and returns to the process (see numeral 187), if the sensor is enabled it makes a reading of the pressure (numeral 188) and verifies if its regulation flag (numeral 189), if it is not, verify that the pressure is within the upper limit (numeral 190), if it is within range now check the lower limit (numeral 191), and if the pressure is very low send a low pressure warning (numeral 192), otherwise the process ends with the reading of the sensors mentioned above. Now, if the pressure is outside the upper limit, first proceed to save the pressure read in a temporary "Pressure_Temp" register (numeral 193), then activate the pressure regulation flag (numeral 194) and adjust the PWM to 50% of the The current "Duty cycle" (numeral 195), this last action is thus conceived because when the pressure sensor is enabled it is normally for applications where direct gas combustion is done and requires a pressure difference between the system and the outlet nozzle of either a burner or a torch for example, then in the event that a pressure is detected outside the programmed upper limit it can imply that the gas outlet valve is closed and by drastically reducing the "Duty cycle" PWM would reduce the rate of increase in system pressure instantaneously; now a 1.5 second wait is made (numeral 196) and the gas pressure is read again (numeral 197), and if the pressure has decreased to the maximum programmed pressure minus 1 PSI (numeral 198) resets the regulation flag ( numeral 1999 and would end with the reading of the sensors, but if the pressure has not been reduced then check if 0.15 PSI has been reduced with respect to the first reading (numeral 200), if it has not been reduced in this small proportion it would mean that in short the valve is closed and sets the duty cycle to 0% of the PWM (numeral 201), on the contrary if this small decrease in pressure has been detected, the process will end with the reading of the sensors without any additional action in the PWM, since it will wait for the next iteration to be evaluated directly if the pressure has decreased to the programmed maximum minus 1 PSI (due to the active pressure regulation flag), and so in next iterations adjust the reactor operating parameters once the pressure decreases.

Returning again to Figure 3, if an error occurs within the PWM regulation process and in other processes that are executed within it, the priority level is first verified (numeral 202), if the error is a priority level 1 then the PWM is set to 0%, that is, the reactor is turned off, then the error code is saved in RAM, the error indication is sent to the user interface module and finally the error flag is activated (numeral 203) to stop timers and stopwatches without enabling their flags, and the system is idle reporting only the error. If the error is of priority level 2, the reactor is shut down (PWM = 0%), saves the error code, sends the error indication, activates the error flag and finally remains monitoring the status of the error until this is corrected or corrected (numeral 204), the above may involve reading a sensor or peripheral, and once the error condition disappears, the error flag (205) is deactivated and the no-send flag is activated ( numeral 206) and the process of reading the sensors (numeral 207) and sending its corresponding status to the user interface module (numeral 208), finally returning to the PWM regulation process by deactivating the "no sent" flag (numeral 209). Each time an iteration of the PWM regulation process ends, it waits for the "Update" timer flag to be enabled once the programmed time elapses (Table II), once it happens it resets the flag (numeral 210) to that in the next cycle you can wait for it to be enabled again, and activate the “no send” flag (numeral 211) now carry out the process of reading the sensors (numeral 2012) saving the data in RAM and proceeding to send the update of the status of the system to the interface module (numeral 213), if an error is detected in the reading of the sensors, go to the stage of verification of the priority of the error (numeral 202) and the flow continues according to the diagram ( explanation in the previous paragraph), finally re-execute the PWM regulation process (numeral 210) when the flag without sending is deactivated (numeral 214) and again this cycle begins again.

At this point we will proceed to explain the interruptions that are threads triggered by a particular event and that can occur at any time interrupting the normal execution of the program to be taken care of and perform a particular task.

Starting with the "Interruption due to gas pipeline cut" (numeral 215), this thread is executed when it is detected that the hose has been cut through which the oxygen gas flows, which can be very delicate since it is a fuel and must be handled with the necessary precautions, so If at this point of the program a priority level 1 error (numeral 216) is returned, proceeding as described above, remembering that at this point the system will stop operating until the problem is corrected, in this case restoring the damaged hose .

The next interruption that can occur is due to the physical disconnection of the user interface module (217), in which upon detecting the condition a priority level 2 error (numeral 218) is returned, proceeding as described above, waiting for that the error changes state, in this case when reconnecting the module.

The following interruption is executed when it detects that the ignition signal is turned off (numeral 219), indicating that the system must be turned off, firstly shutting down the reactor by setting the PWM to 0% (numeral 220), then proceeding to store it in FLASH memory (non-volatile) error codes that have been generated and still remain in RAM (numeral 221), the above because the storage thread stores the error codes every certain time ("storage" timer) and delete the error code once saved, however, if the present interruption occurs when there is an error and the storage time has not arrived, then it is in this point when the error report is saved; on the other hand, the remaining time for service and maintenance is also saved in Flash memory (numeral 222). Finally, the OCU itself is switched off, that is, all the modules of the electronic control (223), in such a way that there is no electricity consumption by the system, which is a point of relevant importance in mobile applications, where the system works with batteries for example of a vehicle. This is where the system flow diagram ends, and once it is turned back on due to the power on signal, the whole process begins again.

The next interruption corresponds to the system programming mechanism, when the programming button is pressed on the remote control the signal is received in the user interface module (number 224), and this module in turn sends commands to the control module that triggers the interruption of programming and in this way a communication is established in which the system is configured through the programming process (numeral 225); This programming process is widely described in the following figure 9.

With reference to Figure 9, this process begins by verifying the security PIN (numeral 226) to access the system, thus providing security, since in this process parameters that directly affect the operation of the reactor are configured, if the PIN is incorrect simply does not allow access to the system of configuration (numeral 226a). First, the selection of the parameter to be configured is verified (numeral 226b), which was made through the configuration menu, and the programming routine is executed:

• PWM manual mode:

When you want to set a percentage of PWM manually, that is, without the system calculating it automatically based on its operating parameters and sensor reading, this option is selected in the programming menu, and the first thing What happens is that an advanced status screen (numeral 227) of the system is displayed in which you can see each and every one of the monitored parameters (voltage, current, electrical power, voltage per cell, electrolyte and power temperatures, pressure , liquid level, percentage of PWM, motor RPMs and global hour meter), unlike the normal operating display screen in which only some of the most relevant parameters (voltage, current, electrolyte temperature, hour meter, level are displayed) of liquid, system pressure and PWM percentage), during the display of this advanced status screen it is possible to change the percentage of PWM by means of the control re motorcycle (numeral 228) and at the same time display the status of the system at a certain point of operation.

In order to have the PWM changed manually, the "manual mode" is enabled (numeral 229), which is verified in the PWM regulation process and in this way allows to change the "Duty Cycle" instantly, disabling the automatic adjustment of the PWM. The data is saved in RAM and transmits data (numeral 230), the action of if it is still configured (numeral 231) is executed if the manual mode is not deactivated in the reactor control (numeral 232), if you want to continue configuring it return to numeral 227.

Once this option to set the PWM manually is exited, then the "manual mode" (232) is disabled, so that the PWM regulation process executes its functions to establish this signal automatically.

• PWM frequency: In this configuration, the frequency of the PWM that is currently programmed is shown first (numeral 233), then a new PWM frequency 8numeral 234 is established, it is validated if it is within range (numeral 235) and if it is not, a valid frequency will have to be established again, if it is in range it is saved in RAM to be subsequently stored in Flash as a configuration parameter (numeral 236), finally it is evaluated if you want to configure again (numeral 237), if not, finish this configuration, if you want to continue configuring return to numeral 233.

Maximum current:

In this configuration you set the maximum current that can consume the reactor, first the currently configured (numeral 238) is displayed and then configured to establish the maximum operating current of the reactor (numeral 239), it is validated that it is within range (numeral 240), if it is not it will have to establish a current that is within range, otherwise it will save the new current in RAM in two registers: 'Maximum programmed current "and" Maximum programmed current 2 "so that the system can perform the algorithms established in the regulation process of PWM (numeral 241). Also at the end it is evaluated if you want to modify it again (numeral 242), if not, conclude this configuration.

• Electrolyte Temperatures and Power:

At this programming point both temperatures are first displayed (if power sensor enabled) see numeral 243, and the maximum reactor electrolyte temperature is first established during reactor operation (numeral 244), then it is validated that it is within of allowed range (numeral 245) to not generate water vapor, then it is verified that the power stage sensor is enabled (numeral 246), if it is not simply this parameter is not configured, if it is configured the maximum temperature that will be allowed in the heat dissipation system of the power transistors that will electrically control the reactor (numeral 247), will be validated if it is in range (numeral 248) and finally the data will be saved in RAM for the subsequent process of saved in non-volatile memory (Flash) see numeral 249. It is determined whether wants to continue configuring (number 250). • Gas pressure:

 First, it is verified that the sensor is enabled (numeral 251, if it is not, it will not be possible to configure this parameter, if it is enabled then the minimum and maximum operating pressures previously configured (numeral 252) will be displayed, then both will be configured (numeral 253) and then it will be verified that the maximum pressure is within the allowed range and that the minimum is less than the maximum (numeral 254), the latter in order for the algorithm to work properly and that the user who configure the system do not make a configuration error by accident, it should also be mentioned that the minimum pressure can be 0 PSI, which would indicate that there is no restriction on the minimum pressure.Finally save the information in RAM (numeral 255), and Determine if you want to continue configuring (numeral 256).

Enabled sensors:

In this configuration, a list of the sensors that are enabled (numeral 257) is first displayed, it is worth mentioning that not all sensors are configurable, which if they are pressure, ducts, power temperature and tachometer, the rest will always be present in the operation of the system. Next, what will be used according to the particular application is chosen to establish its configuration (numeral 258), and finally the ratio of sensors to be used to be stored directly in flash memory is temporarily saved. (numeral 259) and it is determined if you want to continue configuring (numeral 260).

Maintenance time:

Here, the operating time is set up after which a service, maintenance and review of the oxyhydrogen gas generation system should be given. First, the remaining time in which this service is required (numeral 261) is displayed, then it can be modified by setting the new time (numeral 262) and saving it in RAM (numeral 263) and it is determined if you want to continue configuring (264).

^• Timers Configuration:

 At this point in the programming the "Update" and "Storage" timers are configured, the first is the one that dictates when the system status will be updated on the screen and in turn allows the execution of the PWM regulation process; the second timer is the one that establishes the time in which a report of the system status must be stored in memory. First the system displays its previous values (numeral 265), and then allows them to be configured (numeral 266), then it is validated that they are within the range 8numeral 267), once the ranges are validated the data is prepared to be stored in memory Flash (numeral 268) and it is determined if you want to continue configuring (269).

* No. of Cells and Efficiency:

First, the previously configured data (numeral 270) is displayed, then the number of reactor cells is configured that the OCU is governing (numeral 271), it is verified that it is within range (numeral 272) and the data is stored in RAM (numeral 273), then the efficiency parameter is established (numeral 274), which requires the relationship of the gas flow that is produced at a certain electric current (used to calculate the water consumption), the data is finally prepared to be stored in Flash memory (numeral 275) and it is determined if you want to continue configuring (numeral 276).

• Security PIN:

In this configuration option it is possible to modify the access PIN to the programming function of all system configurations, for this it is requested to enter the new security PIN (numeral 277) and confirm it by entering it again 8numeral 278), which allows verifying that they are the same (numeral 279) and that the user has not made an error, in this way the new security password (numeral 280) is saved in RAM and it is determined if you want to continue configuring (281).

RPM ranges:

Finally, the four speed ranges at which the reactor will work at a certain percentage of its capacity are established. For the above, it is first verified that this functionality is enabled (numeral 282), that is, that the tachometer is enabled in the sensor list, and for this it is required that the particular application be in an internal combustion engine. The previous configuration of the speed ranges and their current% of maximum current are displayed below allowed (numeral 283) and subsequently each range is configured, starting with 1 (numeral 284), in which the RPM threshold is established as the reactor begins to produce oxyhydrogen, that is, below this threshold it will be maintained shut down the reactor (PWM = 0%), then set the range 2 in which another maximum limit of RPMs is set in which the reactor will work at A% of its capacity, that is, A% of the current parameter programmed maximum 2 (numeral 285), which will be the same as the programmed maximum as long as the system is not regulating the temperature of the electrolyte inside the reactor, since at this time this current parameter is decreased, as described in the PWM regulation process. Then the range 3 (numeral 286) is established with another speed limit and in this range the reactor is programmed to operate at B% of its capacity (measured in the same terms described in the range 2), and finally automatically configured range 4 (numeral 287), in which the reactor will work at 100% of its capacity when the revolutions exceed the threshold of RPMs of range 3; to conclude this configuration process it is validated that the programmed revolutions do not exceed a maximum limit established (Table III), and that they are progressive, that is, that the first revolution threshold is less than the second, and that the second is less than the third , in order for the algorithm to execute properly (numeral 288), once the above is validated, the configurations are saved in RAM (numeral 289) and it is determined whether it is desired to continue configuring (290).

At the end of each of the configuration options, it is displayed the advanced status screen (numeral 291) to know the sensor values (Voltage, Current, Power, Voltage per cell, Electrolyte Temp, Power Temp, Pressure, Water Level, PWM, RPM, Global Hour Meter), step followed it is determined if you want to exit the programming mode (numeral 292), if not, you return to numeral 226b, and if you are not going to continue configuring the equipment, the new configuration parameters are saved in flash memory (numeral 293 ), so that the changes take effect permanently until a new programming is made, and the process is returned.

While in this programming mode the device continues to regulate the reactor and monitor the sensors and peripherals of the system.

In manual mode it does not regulate with the sensors but if measurements are taken for the status. On the other hand, it will start changing the PWM instantaneously until the update time has elapsed.

Changes in the parameter of Efficiency of the reactor, Enabled and Disabled of sensors, and change in the times of the timers requires to restart the system so that the changes take effect.

It is important to note that during this system programming process the reactor operation continues to be regulated in function to the measurements of the sensors, and as the configuration parameters are changed they take effect immediately except for the efficiency parameters, enabled / disabled sensors and the times assigned to the "Update" and "Storage" timers , until the system restarts.

Finally, if the user does not choose to exit the programming mode, the system will automatically exit this mode after a certain time, the above for security if the user forgets to exit this configuration mode, since there are delicate configurations that affect all operation of the system.

Returning again to figure 3, the interruption of the "Update" timer (numeral 294) consists primarily of checking if the error flag is active (numeral 295) so as not to activate the timer flag, if the error flag is not active then activate the update timer flag (numeral 296) for the main program to detect and perform the programmed functions.

In the interruption of the 1 minute timer (numeral 297) the error flag (numeral 298) is also verified, if this is active then it leaves the interruption without performing any other task, otherwise it increases both global horometers ( numeral 299) as temporary (numeral 300), it also increases the M counter that allows counting minutes (numeral 301), then it is verified if it reached 5 minutes (numeral 302) and activates the 5 minute flag (numeral 303) used in the PWM regulation process by also resetting the M counter to zero (numeral 304) to repeat this last process, finally it is verified if it has reached the service and maintenance time (numeral 305), if it has done so, the corresponding notice is sent to the interface module (numeral 306), otherwise the service and maintenance time is decremented (numeral 307). In the interruption of the "storage" timer (numeral 308), it is first validated if the error flag is active (numeral 309), if it is, then it is checked whether the first time flag is active (numeral 310), if it is not so it means that the error has already been detected and the interruption is exited, otherwise if it is the first time the error is detected the first time flag is deactivated (numeral 311) proceeds to store the monitoring parameters of the reactor in flash memory (numeral 312) through the corresponding process and finally exits the interruption; on the other hand, if there is no error condition, it enables the first time flag (numeral 313) and also stores the monitoring parameters in Flash memory (312). The difference when there is or there is no error is that the error code appears in the report and on the other hand the sensor reading will vary since when the error condition exists the reactor is turned off and the sensor readings change, unlike when the reactor is operating normally. With reference to figure 10, this process is verified First, if the file corresponding to the system status report (numeral 314) exists, if it does not exist, it creates it and formats it for future viewing on a computer (numeral 315). Then proceed to calculate the electrical power consumed by the reactor by multiplying the values that have been measured for current and voltage (W = Vxl), and save the data in RAM (numeral 316), now proceed to calculate and save the voltage in RAM per reactor cell by dividing the total voltage by the number of cells (numeral 317).

Then proceed to write the following system status parameters to the file (numeral 318):

Finally, the generated error codes are deleted from memory RAM (numeral 319) in order not to write the same error several times in the report file. And this way concludes this process. Finally, back to Figure 3, the last interruption corresponds to the mechanism for detecting changes in the status of the system (numeral 320), that is, by sensors and peripherals, for example when updating some value, this in order to update its display in the user interface module. The first thing that is done in this interruption is to verify if the flag "without sending" is active (numeral 321), and if it is, it leaves the interruption since it is the objective of the flag, to inhibit the sending of this update, otherwise, check if it is a change in the voltage or current reading (numeral 322), if it is, proceed to calculate the electrical power consumed by the reactor and save the data in RAM (numeral 323); then it sends to the interface module through the communication port the status of the system parameters that have changed (numeral 324) to update the status of the system in real time, if it were not a change in current or voltage, proceed directly to send the parameters that were detected that were modified. Finally return to normal program execution.
