Description

Technical Field

[0001] The present invention relates to the technical field of engine cooling, and in particular to a method and system for reminding the maintenance of coolant in an agricultural machinery engine. Background Art

[0002] With the upgrade of emissions, the radiators of engines supporting medium and high horsepower products in non-road agricultural machinery (such as tractors, harvesters, harvesters, etc.) basically use antifreeze for cooling and heat dissipation. There are generally requirements for the use of antifreeze, which usually needs to be replaced every two years. At present, the replacement time of antifreeze in agricultural machinery mainly depends on the user. The replacement time cycle of users is long, and it is very likely to exceed the expiration date or even forget to replace it, which will affect the performance of the antifreeze and cause the performance of some engine parts to decrease or use.

[0003] In addition, non-road agricultural machinery products have complex operating conditions, harsh environments, and large vibrations of the entire machine. The radiator is currently an aluminum welded product. Some products may cause leakage at the welding parts due to welding defects, causing antifreeze leakage and causing high engine temperatures, affecting engine use. Long-term operation without timely discovery may cause engine failure. Summary of the invention

[0034] In order to solve the problem of engine failure caused by excessive use of coolant and coolant leakage from radiator, which reduces product reliability and working efficiency, the embodiments of the present application propose an agricultural machinery engine coolant maintenance reminder method, system, device and computer-readable storage medium, which mainly relate to the engine coolant maintenance technology of non-road agricultural machinery products included in the agricultural machinery maintenance technology. These embodiments will be described in detail below.

[0035] First see Figure 1 , Figure 1 The present invention is a flowchart of an exemplary embodiment of an agricultural machinery engine coolant maintenance reminder method. The method can be applied to agricultural machinery equipment equipped with an engine and a radiator, wherein the radiator stores coolant and is connected to the engine to cool and dissipate heat from the engine.

[0036] like Figure 1 As shown, in an exemplary embodiment, the agricultural machinery engine coolant maintenance reminder method may include steps S101 to S105, which are described in detail as follows:

[0037] Step S101, when the engine of the agricultural machinery equipment is in a running state, obtaining a first state information value of the engine coolant.

[0038] In this embodiment, a speed sensor can be used to obtain the engine operation signal of the agricultural machinery equipment. For example, the engine speed is obtained by a shaft crankshaft speed sensor. When the engine speed n is greater than the preset speed threshold nmax corresponding to the engine, it is determined that the engine is in a running state, otherwise it is in an off state.

[0039] Exemplarily, the preset speed threshold nmax is 600 rpm. When the engine speed n is greater than 600 rpm, it is determined that the engine is in a running state. When the engine speed n is less than or equal to 600 rpm, it is determined that the engine is in a flameout state.

[0040] Step S102: If the monitored first status information value is greater than or equal to a preset first status information threshold, a first prompt maintenance information is obtained.

[0041] Step S103: if it is detected that the first state information value is less than a preset first state information threshold, a second state information value of the engine coolant is obtained.

[0042] In this embodiment, while obtaining the real-time first state information value, the magnitude relationship between it and the preset first state information threshold is monitored, and the preset first state information threshold is the preset first state information value corresponding to the engine coolant in the highest limit state. The magnitude relationship can be characterized as the first state information value being greater than or equal to the preset first state information threshold, or can be characterized as the first state information value being less than the preset first state information threshold, and based on the magnitude relationship, the corresponding first prompt maintenance information or further detection action is obtained.

[0043] If the real-time first status information value monitored is greater than or equal to the preset first status information value, it means that the engine coolant is at the preset first status information threshold value under its maximum limit state, and the first prompt maintenance information is obtained; conversely, if the first status information value monitored is less than the preset first status information value, it means that the real-time state of the engine coolant has not reached the preset first status information threshold value under its maximum limit state, and detection is performed to obtain the second status information value of the engine coolant.

[0044] Step S104: if it is detected that the second state information value is less than or equal to a preset second state information threshold, a second prompt maintenance information is obtained, and the second state information value is the coolant level V.

[0045] In this embodiment, while obtaining the real-time second state information value, the magnitude relationship between it and the preset second state information threshold is monitored, and the preset second state information threshold is the preset first state information value Vmin corresponding to the engine coolant level in the lowest limit state. This magnitude relationship can be characterized as the second state information value being less than or equal to the preset second state information threshold, or as the second state information value being greater than the preset second state information threshold, and based on this magnitude relationship, the corresponding second prompt maintenance information is obtained.

[0046] If the real-time second status information value (i.e., coolant level V) monitored is less than or equal to the preset second status information threshold value Vmin, it means that the engine coolant level is at the preset second status information threshold value Vmin under its lowest limit state, and the second prompt maintenance information is obtained; conversely, if the second status information value (i.e., coolant level V) monitored is greater than the preset second status information threshold value Vmin, it means that the real-time state of the engine coolant level has not reached the preset first status information threshold value Vmin under its lowest limit state, and the real-time level V is higher than the preset level Vmin, and there is no need to display the prompt maintenance information.

[0047] Step S105: issuing corresponding warning information based on the first maintenance reminder information or the second maintenance reminder information.

[0048] In this embodiment, when the first status information value is greater than or equal to the preset first status information threshold, the first prompt maintenance information is obtained, and a warning message is issued that the engine coolant is at or exceeds its maximum limit state; or when the first status information value is less than the preset first status information threshold, a warning message is issued that the engine coolant has not reached its maximum limit state, and a message that the coolant is in good condition is issued.

[0049] Furthermore, when the second status information value (i.e., the coolant level V) is less than or equal to the preset second status information threshold value Vmin, the second prompt maintenance information is obtained, and a warning message is issued that the engine coolant level is at its lowest limit state or lower than its lowest level limit state; or when the second status information value (i.e., the coolant level V) is greater than the preset second status information threshold value Vmin, a warning message is issued that the engine coolant has not reached its lowest limit state, and a message that the coolant is in good condition is issued.

[0050] As can be seen from the above, in the method provided in this embodiment, when the engine of the agricultural machinery equipment is in operation, the real-time first status information value of the engine coolant is monitored in real time, and the magnitude relationship between the first status information value and the preset first status information threshold is judged, and the judgment result is used to prompt maintenance and operation through the corresponding first display maintenance information.

[0051] If the real-time first status information value monitored is greater than or equal to the preset first status information value, it means that the engine coolant is at the preset first status information threshold value under its maximum limit state, and the first prompt maintenance information is obtained; conversely, if the first status information value monitored is less than the preset first status information value, it means that the real-time state of the engine coolant has not reached the preset first status information threshold value under its maximum limit state, and detection is performed to obtain the second status information value of the engine coolant.

[0052] From the above, it can be seen that in the method provided in this embodiment, when the engine of the agricultural machinery equipment is in operation, when the real-time first state information value is greater than or equal to the preset first state information threshold, a warning message corresponding to the first prompt maintenance information is output, or when the second state information value (i.e., the coolant level V) is less than or equal to the preset second state information threshold Vmin, the second prompt maintenance information is obtained, and a warning message corresponding to the second prompt maintenance information is output, and the warning message includes a warning message that the coolant is insufficient and maintenance needs to be stopped, that is, coolant needs to be added.

[0053] Through the above technical scheme, the operating status of the engine coolant can be monitored in a hierarchical manner, and the first status and the second status can be monitored successively, and the corresponding first status information value and the second status information value can be obtained respectively, and the first status information value is compared with the preset first status information threshold, and the second status information value is compared with the preset first status information threshold, to obtain the corresponding first prompt maintenance information or the second prompt maintenance information, and issue the corresponding warning information in time, effectively avoiding the occurrence of engine failure caused by overdue use of coolant and coolant leakage from the radiator, and effectively improving product reliability and work efficiency.

[0054] In an exemplary embodiment provided by the present application, the first state information value further includes the coolant temperature t of the engine;

[0055] The preset first state information threshold includes a first threshold Tmax corresponding to the usage time value T and a second threshold tmax corresponding to the coolant temperature t;

[0056] If it is detected that the second state information value is less than or equal to the preset second state information threshold, a second prompt maintenance information is obtained, including:

[0057] If the coolant usage time value T is less than the first threshold value Tmax, determine whether the coolant temperature t is less than the second threshold value tmax;

[0058] If the coolant temperature t is less than the second threshold tmax, a second state information value of the engine coolant is obtained.

[0059] In this embodiment, a temperature sensor can be used to obtain the coolant temperature of the engine of the agricultural machinery equipment. For example, the engine speed is obtained by using a shaft crankshaft speed sensor. If the real-time coolant temperature t is monitored to be greater than or equal to the preset coolant temperature threshold tmax, it means that the engine coolant is at or exceeds the preset coolant usage temperature threshold tmax under its maximum limit state, and the first prompt maintenance information is obtained; conversely, if the real-time coolant temperature t is monitored to be less than the preset coolant temperature threshold tmax, further detection is performed to obtain the second state information value of the engine coolant.

[0060] In another exemplary embodiment, the first reminder maintenance information includes third reminder maintenance information;

[0061] If the coolant usage time value T is greater than or equal to the first threshold value Tmax (preset coolant usage time threshold value Tmax), a third maintenance reminder message is obtained;

[0062] The warning information corresponding to the third maintenance prompt information includes warning information that the coolant needs to be replaced.

[0063] In this embodiment, a speed sensor can be used to obtain the engine operation signal of the agricultural machinery equipment. For example, the engine speed is obtained by a shaft crankshaft speed sensor. When the engine speed n is greater than the preset speed threshold nmax corresponding to the engine, it is determined that the engine is in a running state, otherwise it is in an off state.

[0064] Exemplarily, the preset speed threshold nmax is 600 rpm. When the engine speed n is greater than 600 rpm, it is determined that the engine is in a running state. When the engine speed n is less than or equal to 600 rpm, it is determined that the engine is in a flameout state.

[0065] If it is monitored that the real-time coolant usage time value T is greater than or equal to the first threshold value Tmax, it means that the engine coolant usage time is at or exceeds the first threshold value Tmax under its maximum limit state, and the third prompt maintenance information is obtained; conversely, if it is monitored that the first state information value T is less than the first threshold value Tmax, it means that the engine coolant usage time is shorter than the first threshold value Tmax, and further detection is performed to obtain the second state information value of the engine coolant.

[0066] As a parallel solution of the above embodiment, the use time of the engine can also be monitored directly to indirectly determine the use time of the coolant.

[0067] In this embodiment, the warning information corresponding to the third maintenance prompt information includes warning information that the coolant needs to be replaced.

[0068] That is, if it is monitored that the real-time coolant usage time value T is greater than or equal to the first threshold value Tmax, the third prompt maintenance information is obtained, and at this time, a warning message that the coolant needs to be replaced is issued.

[0069] In another exemplary embodiment, the first reminder maintenance information further includes fourth reminder maintenance information;

[0070] If the coolant temperature t is greater than or equal to the second threshold tmax (preset coolant temperature threshold tmax), a fourth maintenance prompt information is obtained;

[0071] The warning information corresponding to the fourth prompt maintenance information includes engine high temperature warning information.

[0072] In this embodiment, if the real-time coolant temperature t is monitored to be greater than or equal to the second threshold tmax, a fourth maintenance prompt information is obtained. At this time, an engine high temperature warning information is issued, and further cooling is required.

[0073] If the real-time coolant level value V is monitored to be less than or equal to the preset coolant level threshold value Vmin, a second maintenance prompt message is obtained. At this time, a warning message is issued that the coolant is insufficient and maintenance is required.

[0074] In another exemplary embodiment, the method further includes obtaining maintenance confirmation information corresponding to the target prompt maintenance information, and updating the target prompt maintenance information of the engine coolant based on the maintenance confirmation information, wherein the target prompt maintenance information is the first prompt maintenance information or the second prompt maintenance information.

[0075] After the agricultural machinery equipment displays the prompt maintenance information, it can receive the maintenance confirmation information corresponding to the prompt maintenance information. In order to timely and accurately maintain the engine coolant, the engine cooling maintenance information is updated based on the maintenance confirmation information to realize the circulation monitoring and prompt operation of the coolant.

[0076] For example, when the coolant usage time value T is greater than or equal to the first threshold value Tmax, a warning message indicating that the coolant needs to be replaced is issued. After the coolant is replaced, the operator enters maintenance confirmation information to automatically monitor the usage time of the newly replaced engine coolant and record the operating time.

[0077] On the basis of the above embodiment, obtaining maintenance confirmation information corresponding to the target prompt maintenance information, and updating the target prompt maintenance information of the engine coolant based on the maintenance confirmation information, includes:

[0078] Sending the target prompt maintenance information to the operator so that the operator performs corresponding maintenance operations based on the target prompt maintenance information;

[0079] The maintenance confirmation information corresponding to the maintenance operation sent by the operator is received, and the target prompt maintenance information of the engine coolant is updated based on the maintenance confirmation information.

[0080] In this embodiment, when the real-time coolant usage time value T is greater than or equal to the first threshold value Tmax, or the coolant temperature value t is greater than or equal to the second threshold value tmax, the first prompt maintenance information is displayed and the corresponding warning information is issued. The content of the warning information corresponding to the first prompt maintenance information can be: a coolant replacement warning information or an engine high temperature warning information. After receiving the first prompt maintenance, the operator stops the engine for inspection and completes the corresponding maintenance operation, such as replacing the coolant, stopping the engine for cooling, and other maintenance operations. After completion, the maintenance confirmation information is confirmed to update the engine coolant prompt maintenance information and perform a new round of coolant maintenance prompt monitoring operations.

[0081] When the real-time coolant level value V is less than or equal to the preset coolant level threshold value Vmin, the second maintenance reminder information is displayed, and the content of the second maintenance reminder information can be: a warning message that the coolant is insufficient and the machine needs to be shut down for maintenance. After receiving the second maintenance reminder information, the operator shuts down the machine to perform corresponding maintenance operations, such as adding coolant. After completion, the maintenance confirmation information is confirmed to update the engine coolant maintenance reminder information and perform a new round of coolant maintenance reminder monitoring operations.

[0082] The embodiment provided by the present application updates the engine coolant maintenance reminder information based on the maintenance confirmation information by the operator, so as to facilitate automatic monitoring and processing of the coolant again, perform maintenance in time, and improve equipment reliability.

[0083] See also Figure 2 , Figure 3 as well as Figure 4 , Figure 2 is a schematic diagram of an agricultural machinery engine coolant maintenance reminder system shown in an exemplary embodiment of the present application, Figure 3 is a partial installation diagram of an agricultural machinery engine coolant maintenance reminder system shown in an exemplary embodiment of the present application, Figure 4 FIG. 1 is a block diagram of an agricultural machinery engine coolant maintenance reminder system shown in an exemplary embodiment of the present application. Figure 2 , Figure 3 as well as Figure 4 As shown, the schematic diagram of the agricultural machinery engine coolant maintenance reminder system includes:

[0084] The acquisition unit 2 is used to acquire a first state information value of the engine coolant when the engine of the agricultural machinery equipment is in a running state, and acquire a second state information value of the engine coolant when the first state information value is less than a preset first state information threshold;

[0085] The control and processing unit 3 is used to receive the first status information value or the second status information value, and send out the corresponding first reminder maintenance information or the second reminder maintenance information;

[0086] And the display unit 4 is used to receive the first reminder maintenance information or the second reminder maintenance information and issue corresponding warning information.

[0087] It can be seen that the agricultural machinery equipment provided by the above embodiment of the present application implements the agricultural machinery engine coolant maintenance reminder method provided by the present application, which can effectively avoid the initial use of the coolant and the occurrence of engine failure caused by coolant leakage from the radiator, effectively improve product reliability, and improve work efficiency.

[0088] The acquisition unit 2 includes a crankshaft speed sensor 201 , a coolant temperature sensor 202 and a coolant level sensor 203 .

[0089] The crankshaft speed sensor 201 is one of the most important sensors in the control system of the engine 1. It is used to detect the signals of the top dead center of the engine piston and the crankshaft angle and input them into the control and processing unit 3 for controlling the ignition timing and injection timing. It is also a signal source for measuring the speed of the engine 1. The speed of the engine 1 is transmitted to the control and processing unit 3 in real time through the crankshaft speed sensor 201 to determine whether the engine 1 is running.

[0090] The coolant temperature sensor 202 is installed on the engine 1 to detect the coolant temperature of the engine 1. In order to protect the engine 1, the engine 1 sets a coolant maximum temperature threshold tmax. When the temperature value t detected by the coolant temperature sensor 202 is less than tmax, the engine 1 operates normally. When t≥tmax, the engine 1 will operate with limited performance, the engine power will be reduced, and a warning message of engine high temperature will be displayed.

[0091] The coolant level sensor 203 is installed on the upper water chamber of the radiator 101 or the radiator expansion water chamber, and is used to measure the coolant level. In order to protect the heat dissipation of the engine 1, it is ensured that the coolant capacity meets the requirements of the heat dissipation system, and to avoid the lack of coolant causing the coolant temperature to be high and easily generate high-temperature steam, causing damage to the engine. The coolant level sensor 203 detects the calibrated coolant level lower limit position when the liquid level is Vmin. When the liquid level V≤Vmin, it means that the liquid level is lower than the required liquid level height. At this time, the processor 110 will send a message to the display unit 4 to prompt the coolant to be insufficient and shut down for maintenance. When V>Vmin, the coolant level is normal, the engine runs normally, and no information prompt is required.

[0092] The control and processing unit 3 includes an engine control unit ECU 301 and a processor 302. The engine control unit ECU 301 is used to collect engine operation signals and control processing instructions, to receive data values ​​measured by the crankshaft speed sensor 201 and the coolant temperature sensor 202, and to send corresponding data values ​​to the processor 302, which processes the information and sends corresponding first prompt maintenance information or second prompt maintenance information.

[0093] The processor 302 is a whole machine processing unit, which reads the crankshaft speed sensor 201 in the ECU 301, performs comprehensive analysis and judgment based on the data of the coolant temperature sensor 202 and the coolant level sensor 203, and outputs a signal to the display unit 4.

[0094] The engine control unit ECU 301 is connected to an ECU working hours module 303. The ECU working hours module 303 measures the working hours of the ECU 301 when it is running, and is recorded and stored by the ECU 301, and communicates with the processor 302, so that the processor 302 can analyze and determine the running time T of the coolant added to the engine 1. The coolant system sets the usage time to Tmax. When the whole machine reaches Tmax, a prompt message is given that the coolant needs to be replaced.

[0095] The display unit 4 includes a display 401 and a maintenance confirmation information module. The display 401 can receive information from the processor 302 and display it. The maintenance confirmation information module and the processor 302 can perform information maintenance operations to confirm the replacement of the coolant of the engine 1, so that the processor 302 can calculate the usage time of the newly replaced coolant.

[0096] Based on the above embodiment, the agricultural machinery engine coolant maintenance reminder system also includes an update unit 5, which is used to obtain maintenance confirmation information corresponding to the reminder maintenance information, and update the engine coolant reminder maintenance information based on the maintenance confirmation information. The reminder maintenance information is the first reminder maintenance information or the second reminder maintenance information.

[0097] In another exemplary embodiment, the updating unit 5 sends the prompt maintenance information to the operator, so that the operator performs a corresponding maintenance operation based on the prompt maintenance information;

[0098] The maintenance confirmation information corresponding to the maintenance operation sent by the operator is received, and the prompt maintenance information of the coolant of the engine is updated based on the maintenance confirmation information.

[0099] It should be noted that the agricultural machinery engine coolant maintenance reminder system provided in the above embodiment and the agricultural machinery engine coolant maintenance reminder method provided in the above embodiment belong to the same concept, wherein the specific manner in which each module and unit performs the operation has been described in detail in the method embodiment, and will not be repeated here. In actual application, the agricultural machinery engine coolant maintenance reminder system provided in the above embodiment can allocate the above functions to different functional modules as needed, that is, divide the internal structure of the device into different functional modules to complete all or part of the functions described above, and this is not limited here.
