Description

Agricultural machinery fuel cell gas filling device, gas filling system and gas filling method thereof

Technical Field

The invention relates to the field of energy supplement, in particular to an agricultural machinery fuel cell gas filling device, a gas filling system and a gas filling method thereof.

Background

Agricultural machinery is a general name of common machinery in agriculture at present, and can largely replace manual labor with mechanical labor, thereby greatly liberating productivity. The traditional agricultural machinery is powered by fuel oil, and the requirement on clean energy is increasingly urgent along with the development of times, because the traditional fuel oil agricultural machinery is noisy in the using process, and waste emissions of the traditional fuel oil agricultural machinery can be diffused into the air to cause air pollution and even induce diseases, such as respiratory diseases, cardiovascular diseases and the like to cause great harm to the bodies of agricultural machinery operators. In addition, the waste emissions from the conventional oil-burning agricultural machinery may cause damage to crops, especially when used in a sealed environment, because the waste emissions from the oil-burning agricultural machinery cannot be diffused quickly and remain in the sealed environment, so that the waste emissions may cause damage to crops in the sealed environment, such as a greenhouse environment. The fuel cell is a clean and efficient new energy source, and has a plurality of advantages, for example, the fuel cell provides power for agricultural machinery by converting chemical energy into electric energy, the fuel cell has almost no noise in the whole process, and meanwhile, most products are moisture and almost have no pollution to the environment, so the agricultural machinery with the fuel cell has a great development prospect.

However, there are also problems that limit the development of agricultural machinery with fuel cells. For example, compared with a conventional vehicle with a fuel cell, an agricultural machine is generally designed to be suitable for use in a farm field, that is, the traveling speed of the agricultural machine is slow, which causes a problem because for the fuel cell, a chemical reaction between fuel and reactant is required continuously to obtain chemical energy and then electric energy, once the fuel or reactant is consumed, the fuel cell stops supplying energy immediately, so that the agricultural machine with the fuel cell cannot work normally, and a user needs to supply energy to the fuel cell in time when the user wants to reuse the fuel cell. A typical vehicle with a fuel cell is powered by driving the vehicle to a stationary charging station before the energy is exhausted, and then re-using the vehicle for the user after the charging station is charged.

For agricultural machinery, charging in such a way may take a very long time and consume a large amount of electric energy on the way back, and it may be very difficult to charge agricultural machinery with a fuel cell in a large or remote area, thereby limiting the use of agricultural machinery with a fuel cell.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.

A fuel cell is a device for supplying power to other devices by converting chemical energy into electric energy, and thus the fuel cell can be installed in a plurality of devices requiring electric energy to supply power thereto. Such as vehicle-mounted fuel cells, fuel cell phones, etc. The fuel cell can provide electrical power to other devices on an ongoing basis as long as there is an uninterrupted supply of fuel and reactants, i.e., the fuel cell need only be fueled to generate electrical power, and for rechargeable batteries, it takes a waiting period to charge once the power is exhausted. In a word, the fuel cell has wide application prospect.

When fuel cells are used in agricultural machinery, air pollution of the agricultural machinery during use can be reduced because agricultural machinery generally has a large volume, requires a large amount of power, and a user may need to operate beside the agricultural machinery or monitor the use of the agricultural machinery during use, that is, the user is exposed to an environment in which the user is more likely to inhale exhaust gas generated by a conventional oil-fired agricultural machinery. On the other hand, the agricultural machine with the fuel cell also reduces the noise of the agricultural machine in the using process, and provides a clean and comfortable using environment for users.

However, for agricultural machinery with fuel cells, how to supplement energy after the energy in the fuel cells is exhausted is an urgent problem to be solved.

Fuel cells come in many types, the most common of which is hydrogen fuel cells, because the end product of hydrogen fuel cells is water only, and certainly an ideal energy source. Hydrogen fuel cells require hydrogen gas as a fuel and then chemically react with oxygen in the air to provide electrical power. When the hydrogen is exhausted, the fuel cell stops working and cannot supply energy to the agricultural machinery. Therefore, the agricultural machine with the fuel cell has to pay attention to timely supplement of hydrogen during use so as to avoid influencing the normal operation of the agricultural machine.

It should be noted that, in the above description, the fuel cell aeration system is described by taking hydrogen as an example, but this does not limit the type of fuel, and other gases such as methane may be used.

Referring to fig. 1 and 2, a preferred embodiment of the present invention provides an agricultural fuel cell aeration system for charging an agricultural machine with a fuel cell.

In the following description, the agricultural fuel cell gas filling system is simply referred to as the gas filling system.

The gas filling system comprises a data acquisition unit 10 and a processing unit 20, wherein the data acquisition unit 10 is communicably connected to the processing unit 20, the data acquisition unit 10 acquires the state of a fuel cell of the agricultural machine with a fuel cell by externally connecting the agricultural machine with a fuel cell, and generates a gas filling signal according to the state of the fuel cell, and the processing unit 20 can receive the gas filling signal and generate a gas filling instruction according to the gas filling signal, so that gas can be supplied to the fuel cell when the gas filling instruction is executed subsequently.

Further, the gas filling system comprises a energy supply unit 30, wherein the energy supply unit 30 is communicably connected to the data acquisition unit 10 and the processing unit 20, respectively, so that the data acquisition unit 10 can acquire data from the energy supply unit 30, so that the processing unit 20 can process related information about the energy supply unit 30. The energy supply unit 30 comprises at least one gas filling device 31, wherein the gas filling device 31 can receive the signal from the processing unit 20 and then go to a position where gas filling is needed to provide gas filling service.

The data acquiring unit 10 further comprises a detecting module 11 and a positioning module 12, wherein the detecting module 11 is used for detecting the hydrogen gas remaining amount of the fuel cell, and the positioning module 12 is used for acquiring the position information between the gas adding device 31 and the fuel cell needing gas adding.

When the detection module 11 detects that the hydrogen content of the fuel cell in the agricultural machinery with the fuel cell is lower than a preset value, the gas filling signal is sent out, wherein after the processing unit 20 receives the gas filling signal, the processing unit 20 generates a route for the gas filling device 31 to go to the position of the fuel cell needing gas filling according to the position information between the gas filling device 31 and the fuel cell needing gas filling, which is acquired by the positioning module 12. That is, the gas adding device 31 is a mobile gas adding device, so that when the gas adding system determines that the agricultural machine with the fuel cell needs to add gas, the gas adding device 31 can go to the position of the agricultural machine with the fuel cell according to the route generated by the gas adding system and provide gas adding service for the fuel cell of the agricultural machine with the fuel cell. The gas charging means provided by the gas charging system of the present invention is unexpected in the case of the fixed gas charging devices of the prior art, and the means provided by the gas charging system of the present invention to go to the location of the fuel cell-equipped agricultural machine through the mobile gas charging device and supplement gas to the fuel cell of the fuel cell-equipped agricultural machine is particularly important for the fuel cell-equipped agricultural machine.

For example, when the remaining amount of hydrogen in the fuel cell of the agricultural machine with a fuel cell is insufficient for the agricultural machine with a fuel cell to normally work, or the remaining amount of hydrogen in the fuel cell is lower than the preset value, the detection module 11 for detecting the remaining amount of hydrogen in the fuel cell detects the state of the fuel cell and subsequently allows the data acquisition unit 10 to provide the gas filling signal so as to subsequently enable the corresponding fuel cell to obtain gas filling service. It should be understood that the detection module 11 can detect the hydrogen remaining amount of the fuel cell by externally connecting to the electrical system of the agricultural machinery with the fuel cell, for example, the agricultural machinery with the fuel cell is provided with a hydrogen remaining amount detector (such as, but not limited to, a liquid level sensor) for detecting and feeding back the hydrogen remaining amount of the fuel cell at any time, wherein the data fed back by the hydrogen remaining amount detector can be received by the detection module 11 through the electrical system of the agricultural machinery with the fuel cell. In other words, the detection module 11 can detect the hydrogen remaining amount of the fuel cell by externally connecting the hydrogen remaining amount detector of the agricultural machine with the fuel cell. Alternatively, in an embodiment of the present invention, the detecting module 11 may be a detector connected to the agricultural machine with the fuel cell to detect the remaining amount of gas.

It is understood that, in an embodiment provided by the present invention, the detecting module 11 includes a remaining amount detecting module 111, a communication module 113 and a judging module 112, wherein the remaining amount detecting module 111 is communicably connected to the communication module 113, wherein the judging module 112 is communicably connected to the remaining amount detecting module 111 and the communication module 113, wherein the judging module 112 is communicably connected to the remaining amount detecting module 111, wherein the remaining amount detecting module 111 is used for detecting the remaining amount of hydrogen gas in the fuel cell and the remaining amount of fuel that can be provided by the gas adding device 31, when the remaining amount detecting module 111 detects the remaining amount of hydrogen gas in the fuel cell, the detected data is sent to the judging module 112, a judging result is obtained through the processing of the judging module 112, and the judging module 112 sends the judging result to the communication module 113, if the remaining amount of hydrogen in the fuel cell is lower than a threshold value, which makes the fuel cell unable to function normally, or lower than the preset value, which makes the fuel cell need to be charged in time, the communication module 113 transmits the gas filling signal to the processing unit 20 when receiving the determination result sent by the determination module 112, and if the remaining amount of hydrogen in the fuel cell is higher than or equal to the threshold value, which makes the fuel cell unable to work normally, or higher than or equal to a preset value, which makes the fuel cell need to be charged in time, the communication module 113 does not generate the gas filling signal to the processing unit 20. In other words, the remaining amount detecting module 111 may detect the remaining amount of hydrogen of the fuel cell by externally connecting a hydrogen remaining amount detector of the agricultural machinery with the fuel cell, and detect the remaining amount of hydrogen of the gas adding device 31 by externally connecting a hydrogen remaining amount detector of the gas adding device 31.

That is, when the agricultural machine with a fuel cell needs to be provided with gas filling service, the gas filling system can select the gas filling device 31 for providing gas filling service to the agricultural machine with a fuel cell, and one of the selected conditions is whether the type of gas provided by the gas filling device 31 matches the type of gas used by the agricultural machine with a fuel cell, and the other selected condition is that the gas filling device 31 has enough gas to provide gas filling service to the agricultural machine with a fuel cell. It will therefore be appreciated by those skilled in the art that if the gas-filling device 31 does not meet either of the above two conditions, the gas-filling device 31 cannot provide gas-filling service for the agricultural machine with the fuel cell, so that after the gas filling system detects that the agricultural machine with the fuel cell needs to be provided with gas filling service, it is first detected whether the type of gas that the gas-adding device 31 located in the vicinity of the fuel cell equipped agricultural machine can provide matches the gas used by the fuel cell equipped agricultural machine, if so, further determining whether the gas adding device 31 has enough gas to provide gas adding service for the agricultural machinery with the fuel cell, if so, the gas filling system provides the route for guiding the gas filling device 31 to provide gas filling service for the agricultural machine with the fuel cell.

It should be noted that the determination criteria of the determination module 112 can be set manually by the user, i.e. the gas filling system has a built-in determination criteria, for example, the gas filling signal is sent when the determination criteria is lower than a specific value. The user can also adjust the judgment standard according to the needs of the user, because for the agricultural machine with the fuel cell, the gas filling signal can be sent when the hydrogen of the fuel cell is about to be exhausted, so that the fuel cell cannot be normally used in the process of waiting for gas filling, the user can set a numerical value to ensure that the numerical value has certain working time when the numerical value is away from the condition that the agricultural machine with the fuel cell cannot completely normally work, the situation that the agricultural machine with the fuel cell is vacant is avoided, and the use efficiency of the agricultural machine with the fuel cell is improved as much as possible.

In another example, the determination module 112 can also provide a dynamic determination criterion to select the timing when the fuel cell of the farm machine with a fuel cell needs to be provided with gas filling service. For example, the detection module 11 is configured to detect a remaining amount of hydrogen in the fuel cell and an amount of hydrogen consumed by the agricultural machinery with a fuel cell in a unit time, and detect a position of the gas-filling device 31 capable of providing gas-filling service for the agricultural machinery with a fuel cell, and the gas-filling system is configured to select a timing at which the fuel cell of the agricultural machinery with a fuel cell needs to be provided with gas-filling service according to the remaining amount of hydrogen in the fuel cell, the amount of hydrogen consumed by the agricultural machinery with a fuel cell in a unit time, and the position of the gas-filling device 31. For example, in a specific example of the gas adding system of the present invention, even if the remaining amount of hydrogen gas of the fuel cell is small, if the amount of hydrogen gas consumed by the agricultural machine with a fuel cell per unit time is small and/or the gas adding device 31 is located close to the agricultural machine with a fuel cell, the gas adding system may maintain the agricultural machine with a fuel cell for a long operation time without sending the gas adding signal. In another specific example of the gas adding system of the present invention, even if the remaining amount of hydrogen of the fuel cell is relatively large, if the amount of hydrogen consumed by the agricultural machine with a fuel cell in a unit time is large and/or the gas adding device 31 is far away from the agricultural machine with a fuel cell, the gas adding system must send the gas adding signal to allow the gas adding device 31 to go to the location of the agricultural machine with a fuel cell to provide gas adding service for the fuel cell, otherwise the agricultural machine with a fuel cell cannot operate normally.

Specifically, the remaining amount detecting module 111 includes at least one to-be-charged device remaining amount detecting module 1111 and at least one to-be-charged device remaining amount detecting module 1112, wherein the to-be-charged device remaining amount detecting module 1111 is configured to detect a remaining amount of fuel of the fuel cell, wherein the to-be-charged device remaining amount detecting module 1112 is configured to detect a remaining amount of fuel that can be provided by the gas charging device 31, so that the gas charging system can schedule the gas charging device 31 according to the remaining amount of hydrogen of each gas charging device 31 to avoid that the remaining amount in the gas charging device 31 cannot provide a sufficient amount of gas for the fuel cell that needs to be charged, wherein the gas charging device remaining amount detecting module 1112 is communicably connected to the communication module 113 to allow the remaining amount of hydrogen of the gas charging device 31 to be transmitted to the processing unit 20.

The positioning module 12 is communicatively coupled to the processing unit 20 such that the processing unit 20 can receive the position information collected by the positioning module 12.

Specifically, the positioning module 12 includes a gas filling device positioning module 122 and a gas filling device positioning module 121, wherein the gas filling device positioning module 122 and the gas filling device positioning module 121 are respectively communicably connected to the processing unit 20, wherein the gas filling device positioning module 122 is used for positioning the position of the gas filling device 31 capable of providing gas filling service, and wherein the gas filling device positioning module 121 is used for positioning the position of the device to be provided with gas filling service, that is, the position of the agricultural machinery with fuel cell which needs to be filled with gas. It will be understood by those skilled in the art that the location of the to-be-aerated device positioning module 121 can be directly the location of the agricultural machinery with the fuel cell to be aerated, or can be a location preset by the user of the fuel cell, so that the aeration system can provide aeration service according to the user's needs.

When the processing unit 20 receives the air-entrapping signal sent by the detection module 11, the processing unit 20 processes the air-entrapping signal and the position information sent by the positioning module 12 to provide a reasonable air-entrapping scheme, so that the air-entrapping system can provide air-entrapping service for the fuel cell of the agricultural machinery with the fuel cell at the lowest cost and the fastest speed.

Specifically, the processing unit 20 includes a data processing module 21 and a data generating module 22, wherein the data processing module 21 is used for processing the data acquired by the data acquiring unit 10, and wherein the data generating module 22 is communicatively connected to the data processing module 21 for generating the air filling instruction. In other words, the data processing module 21 is communicably connected to the data acquiring unit 10, so that the data processing module 21 can receive and process the gas filling signal provided by the data acquiring unit 10, and the data generating module 22 can generate the gas filling command according to the processing result of the data processing module 21, so that subsequently, when the gas filling device 31 receives and executes the gas filling command from the data generating module 22, the gas filling device 31 can provide gas filling service for the fuel cell of the agricultural machinery with fuel cell.

It will be appreciated that the processing unit 20 may be implemented as a processor, such as a CPU, wherein the processor may be connected to the aeration device or to the fuel cell equipped agricultural machinery or to a central service processor.

When the processing unit 20 receives the gas filling signal from the data acquiring unit 10, the data processing module 21 processes the hydrogen remaining amount data detected by the remaining amount detecting module 11 of the data acquiring unit 10 and the position information acquired by the positioning module 12. For example, the data processing module 21 first searches for the gas filling device 31 according to the position information acquired by the positioning module 12, searches for the gas filling device 31 near the fuel cell that needs to be filled with gas so as to provide gas filling service in time, selects the gas filling device 31 that saves the most time for providing gas filling service to the user according to a preset program, and compares the hydrogen remaining amount of the selected gas filling device 31 with the required hydrogen amount through the detection module 11, if the gas filling device 31 also has sufficient hydrogen remaining amount to provide service for the fuel cell, then selects the gas filling device 31 as a gas filling service provider. If the selected gas adding device 31 does not have enough hydrogen allowance, the gas adding device 31 is removed, then the selection and the judgment are carried out again according to the information of the positioning module 12, and a target gas adding device 31 is selected for adding gas to the fuel cell to be added through the processing of the data processing module 21.

It will be understood by those skilled in the art that the above-described data processing procedure of the data processing module 21 is only an example, and may be the above-described procedure but is not limited thereto. The data processing module 21 may also be configured to remove the gas adding device 31 that cannot meet the demand by using the hydrogen remaining amount detected by the detecting module 11, and then select the gas adding device 31 by using the position information acquired by the positioning module 12.

The gas filling system further comprises an interaction unit 40, wherein the interaction unit 40 is used for interaction between a user of the fuel cell to be filled and the gas filling system, wherein the interaction unit 40 is communicatively connected to the processing unit 20. Specifically, when the data processing module 21 obtains a proposed gas dispensing device 31 according to a preset program, the interaction unit 40 may feed back the result to the user, and the user may determine whether to approve according to his/her needs, and if so, perform the following steps. If the user disagrees, the user can select the gas adding device 31 according to the requirement by operating the interaction unit 40, and the selection result is recorded by the processing unit 20.

After the above operations are completed, the data processing module 21 sends a selection result to the data generating module 22 after processing the data, and the data generating module 22 plans a reasonable route between the selected gas filling device 31 and the destination according to the selection result so that the gas filling device 31 can reach the destination to provide gas filling service.

In the present invention, the gas filling device 31 refers to a movable device carrying hydrogen, and may be a vehicle, an airplane, a ship, or the like, and the gas filling device 31 may be operated by an operator, such as a driver, or may be automatic, such as unmanned aerial vehicle delivery.

It is understood that the gas filling device 31 may also communicate with customers, i.e. gas filling service consumers, via the interaction unit 40, either automatically or by an operator of the gas filling device 31. For example, when a vehicle type gas filling device encounters a sudden accident such as traffic jam, storm, snow and the like during operation and cannot reach a predetermined destination, the interaction unit 40 can notify a customer in time, and adjust a gas filling process in time according to the customer's requirement, for example, a new gas filling device 31 is dispatched to provide services for the customer from other ways. At the same time, the operator can also actively transmit this information to the filling system via the interactive unit 40, so that the filling system can in time rearrange the filling device 31 for the customer to fill.

It is worth mentioning that the customer can also request a gas filling service according to his or her needs through the interaction unit 40, for example, select a gas filling place and time, this makes it possible for the customer to choose when and where to fill the gas, exactly as he/she needs, the interaction unit 40 sending this filling demand of the customer to the processing unit 20, the processing unit 20 may perform data processing according to the data acquired by the data acquiring unit 10, first search for the gas adding device 31 that is idle for a specified period of time, then, a recommendation result is obtained according to the hydrogen surplus and the demand quantity and the positions of the gas adding device 31 and the fuel cell and is fed back to the user, the user confirms the recommendation result and then the user is equivalent to the reservation of gas adding service, the gas filling system will arrange for the selected gas filling device 31 to serve the user in a timely manner.

That is, the gas filling system can provide gas filling service for the fuel cell to be filled in an active manner, that is, the data acquisition unit 10 feeds back corresponding data to the processing unit 20. The gas filling system can also request a gas filling service for the fuel cell to be filled in a passive manner, i.e. the user contacts the processing unit 20 directly via the interaction unit 40.

It should be noted that the data acquiring unit 10 can acquire the instant location information of the gas filling device positioning module 122 and the gas filling device positioning module 121, and transmit the location information to the processing unit 20, so that the gas filling system can change the route or the gas filling time in time according to the location change.

For example, when the gas filling device 31 receives a gas filling command transmitted by the processing unit 20, the gas filling device 31 goes to a designated gas filling position according to a route planned by the gas filling system, but it is understood that a user of the gas filling device 31 can adjust the route according to his or her own needs. For example, the road condition changes, the influence of weather, some accidents, etc., and the data obtaining unit 10 feeds back the information to the processing unit 20 through the position information obtained by the positioning module 12, and the route change of the processing unit 20 is fed back to the user of the gas filling device 31 or the user of the fuel cell to be filled in time. For example, the filling time is delayed so that a user of the fuel cell to be filled can arrange the device to be filled in advance. Conversely, the gas filling system may also adjust the gas filling device 31 in time according to the change of the position to be filled or the change of the demand fed back by the user needing gas filling through the interaction unit 40.

The gas filling device 31 can store hydrogen and transport the hydrogen to a designated place to provide convenient gas filling service for use. That is, the position of the gas adding device 31 is not fixed, and the position of the gas adding device 31 can be changed according to different requirements of users. For example, in a relatively remote area, it is difficult for a user to transport an agricultural machine to be aerated or to directly drive the agricultural machine to a fixed aeration point in an urban area, and then the user can aerate the agricultural machine by the mobile aeration device 31. Alternatively, for users, some of the fuel cells installed on the farm machinery with fuel cells are bulky in the past, or even cannot be detached from the farm machinery with fuel cells and transported to a fixed gas filling point for gas filling, the mobile gas filling device 31 relieves the dilemma and it is worth mentioning that the users do not need to spend much time and energy for gas filling, such as carrying the fuel cells back and forth or running the farm machinery with fuel cells, but can wait for the gas filling device 31 to serve at the door, which undoubtedly greatly facilitates the use of the farm machinery with fuel cells and facilitates the popularization of the fuel cells. This makes it increasingly desirable to use the agricultural machine with a fuel cell, especially for the agricultural farmers who have many agricultural machines.

When the gas dispensing device 31 is about to reach a designated location, i.e. a destination, the interaction unit 40 will send a prompt signal to the user to prompt the user to enjoy gas dispensing services at the location appointed by the user. The gas filling system fills gas for the fuel cell to be filled and a user needs to pay a certain fee for gas filling service.
