Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention. , not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

It should be noted that the terms "first", "second" and the like in the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific sequence or sequence.

FIG. 1 is one of the schematic flow charts of the method for reminding maintenance of a working machine provided by the present invention. As shown in FIG. 1 , the method includes step 110 , step 120 , step 130 and step 140 .

Step 110: Obtain the operation time of the working machine.

Specifically, the working machine may be a construction machine such as a crane, an excavator, and a pile driver, or a construction vehicle such as a climbing truck, a fire truck, and a mixer truck. The execution object of the working machine maintenance reminder method provided by the embodiment of the present invention may be a controller of the working machine or the like.

The controller of the work machine can communicate with the user terminal, the remote monitoring system of the work machine, the engineer terminal, etc. for data transmission.

Different from the existing road vehicles that use the mileage or a fixed time period as the maintenance basis, the maintenance basis of the work machine can be the operation time. The operation time is the length of time during which the user operates the working parts of the work machine to perform construction work.

The controller of the work machine can record and accumulate the operation time of the work machine to obtain the operation time.

Step 120: If the operation duration is greater than or equal to the operation duration threshold of the work machine at the current maintenance node, obtain a service order within the maintenance time period corresponding to the current maintenance node.

Specifically, the maintenance node of the work machine is a time node when the work machine is repaired and maintained. As the length of time a work machine is operated increases, so does the degree of equipment damage. Therefore, a plurality of maintenance nodes can be provided to the work machine, and consumable parts or damaged parts in the work machine can be repaired or replaced. The operation duration threshold of the current maintenance node is the required value of the operation duration of the work machine after completing the maintenance at the previous maintenance node before triggering the work machine to enter the current maintenance node for maintenance, and the unit can be hours.

For example, for an excavator, 5 maintenance nodes can be set, and the operation duration threshold corresponding to each maintenance node can be set to 100 hours. That is to say, when the total operation time of the work machine reaches 100 hours, the first maintenance node is triggered, and when the total operation time of the work machine reaches 200 hours, the second maintenance node is triggered, and when the total operation time of the work machine reaches 200 hours Trigger to enter the third maintenance node after 300 hours, trigger to enter the fourth maintenance node when the total operation time of the work machine reaches 400 hours, and trigger to enter the fifth maintenance node when the total operation time of the work machine reaches 500 hours.

To determine whether the operation time meets the operation time threshold of the work machine at the current maintenance node, it is necessary to count the operation time of the work machine after the maintenance is completed at the previous maintenance node, and compare the statistical result with the operation time threshold of the current maintenance node. The result determines whether it is satisfied. For example, if the current maintenance node of the excavator is the second maintenance node, it is necessary to count the operation time of the excavator after the maintenance is completed at the previous maintenance node (the first maintenance node). If the operation time is greater than or equal to 100 hours, it is determined that the operation time threshold of the excavator at the current maintenance node is met, and the second maintenance node can be triggered to determine whether to remind the user of the operation machine for maintenance; if the operation time is less than 100 hours , then it is determined that the operation duration threshold of the excavator at the current maintenance node is not met, and maintenance reminder is not required.

Since the operation machinery adopts a maintenance service model in which the customer makes an active appointment, issues a service order, and the service engineer provides on-site service according to the service order. A service order here is an order requesting maintenance service for a work machine. In the actual maintenance process of the working machine, in most cases, the customer requires the maintenance to be performed in advance before the arrival of the current maintenance node, or the maintenance is delayed after the arrival of the current maintenance node. Therefore, when the work machine enters the current maintenance node, how to judge whether to remind the user of the work machine for maintenance, you can obtain the service order in the maintenance time period corresponding to the current maintenance node, and determine whether to carry out the maintenance reminder according to the service order.

Considering that the execution time of the service order may appear before the arrival of the current maintenance node (corresponding to the service order that has been executed), it may also appear after the arrival of the current maintenance node (corresponding to the service order scheduled to be executed). The corresponding maintenance time period can be set for the current maintenance node, and the service orders whose execution time is within the maintenance time period can be obtained.

The maintenance time interval can be set to determine the maintenance time period corresponding to the current maintenance node. For example, if the operation duration threshold between the last maintenance node and the current maintenance node is 100 hours, the maintenance interval can be set to 50 hours, and the maintenance time period corresponding to the current maintenance node is [operation time corresponding to the current maintenance node- 50 hours, the operation time corresponding to the current maintenance node is +50 hours].

Step 130: Based on the order type and service item of the service order, determine whether the service order meets the maintenance requirements of the work machine at the current maintenance node.

Specifically, the service order may be actively submitted by the user through the user terminal, or may be automatically generated by the work machine remote monitoring system after monitoring the operation time of the work machine.

Service orders include three types of service orders, namely repair, maintenance and inspection. Among them, the service order of the maintenance type is generally issued by the user through the user terminal, and is used to repair or replace the parts in the working machine. Maintenance-type service orders are generally automatically generated by the user through the user terminal or by the remote monitoring system of the work machine after monitoring the operation time of the work machine, and are used to provide maintenance services for the work machine. Service orders of the inspection type are generally issued by the inspection personnel through the inspection client when the inspection personnel conduct inspections of the operation machinery, and are used to perform irregular maintenance inspections on the parts in the operation machinery.

The service items of the work machine during maintenance at the current maintenance node can include two categories: maintenance inspection items and parts replacement items. These service items can appear in maintenance-type service orders, and may also appear scattered in maintenance-type and inspection-type service orders. For example, when the excavator enters the current maintenance node, the service items that it needs to complete are all completed in the recent maintenance and inspection, it can be determined that the excavator does not need to be maintained at the current maintenance node, nor does it need to be reminded of maintenance.

Therefore, when considering whether to perform maintenance reminders, it is necessary to comprehensively consider the order types and service items of each service order in the maintenance time period corresponding to the current maintenance node.

Determining whether the service order meets the maintenance requirements of the work machine at the current maintenance node is to determine whether the service items of each service order include all the service items when the work machine is maintained at the current maintenance node.

Step 140: If the service order meets the maintenance requirement, set the maintenance status of the work machine based on the execution time of the service order; if the service order does not meet the maintenance requirement, push maintenance reminder information.

Specifically, if the service order meets the maintenance requirements, it indicates that all the service items that the operation machine needs to perform at the current maintenance node have been performed or are waiting to be performed, and there is no need to remind the user of maintenance. to set the maintenance status. For example, if the execution time of the service order is before the current maintenance node, the maintenance status of the work machine can be set as maintained; if the execution time of the service order is after the current maintenance node, the maintenance status of the work machine can be set as pending maintainance. In this process, there is no need to remind users of maintenance, so as to avoid interference to users during construction operations.

If the service order does not meet the maintenance requirements, it means that the service items that the operation machine needs to perform at the current maintenance node have not been considered by the user and have not been generated in the remote monitoring system. The display screen of the center console pushes and displays maintenance reminder information, and can also push maintenance reminder information to the user's mobile terminal.

In the work machine maintenance reminder method provided by the embodiment of the present invention, if the operation time of the work machine is greater than or equal to the operation time threshold of the work machine at the current maintenance node, the service order in the maintenance time period corresponding to the current maintenance node is obtained, and according to the service order If the service order meets the maintenance requirements, the maintenance status of the operation machine will be set according to the execution time of the service order; if the service order does not meet the maintenance requirements If the maintenance needs are met, the maintenance reminder information will be pushed. Since the maintenance time node of the work machine itself and the actual maintenance situation of the work machine are considered, it can accurately judge whether to remind the user for maintenance, which reduces the information caused to the operator. Interference, improve the maintenance reminder effect of the working machine, and improve the working efficiency of the working machine.

Based on the above embodiment, step 130 includes:

If there is a service order whose order type meets the preset order type, and the service items in the service order include the maintenance inspection items and/or parts replacement items of the current maintenance node, it is determined that the service order meets the maintenance requirements;

Wherein, the preset order type includes at least one of maintenance, repair and inspection.

Specifically, generally speaking, a service order that includes maintenance inspection items and/or parts replacement items generally includes three categories: maintenance, repair, and inspection. Therefore, the above three order types can be used as preset order types to determine whether the service orders existing in the maintenance time period meet the maintenance requirements of the current node. As long as the service items in the orders of at least one type of the preset order types include the maintenance inspection items and the parts replacement items of the current maintenance node, it is determined that the service order meets the maintenance requirements.

For example, if there is a first service order with an order type of maintenance in the maintenance time period corresponding to the current maintenance node, the service items in the first service order can be matched with the maintenance inspection items and parts replacement items of the current maintenance node. If the service items in the first service order include maintenance inspection items and parts replacement items of the current maintenance node, it indicates that the first service order can meet the maintenance requirements of the current maintenance node.

For another example, if there is no first service order whose order type is maintenance within the maintenance time period corresponding to the current maintenance node, but there is a second service order whose order type is maintenance. Then, the service items in the second service order can be matched with the maintenance inspection items and parts replacement items of the current maintenance node. If the service items in the second service order include maintenance inspection items and parts replacement items of the current maintenance node, it indicates that the second service order can meet the maintenance requirements of the current maintenance node.

For another example, if there is no first service order whose order type is maintenance within the maintenance time period corresponding to the current maintenance node, but there is a third service order whose order type is patrol inspection. Then, the service items in the third service order can be matched with the maintenance inspection items and parts replacement items of the current maintenance node. If the service items in the third service order include the maintenance inspection items and parts replacement items of the current maintenance node, it indicates that the third service order can meet the maintenance requirements of the current maintenance node.

Based on any of the above embodiments, after step 140, the method further includes:

receive message elimination instructions;

In response to the message elimination instruction, push the warning information corresponding to the maintenance reminder information;

Receive message clearing confirmation instruction;

Eliminate the confirmation instruction based on the message, and eliminate the maintenance reminder message.

Specifically, the working machine maintenance reminder method provided by the embodiment of the present invention can also be applied to the situation where the user forcibly removes the maintenance reminder information.

When the displayed maintenance reminder information causes information interference to the user, the user can issue a message elimination instruction through the user terminal. After the controller of the work machine receives the message elimination instruction, it can send the warning information corresponding to the maintenance reminder information to the user terminal, which is used to warn the user of risks and remind the user of the possible consequences of forcibly eliminating the maintenance reminder information. The user can input feedback information in the user terminal after reading the warning information. The user terminal generates a message cancellation confirmation instruction according to the feedback information.

The controller of the work machine can clear the maintenance reminder message after receiving the message clearing confirmation command.

Based on any of the above embodiments, step 120 includes:

Obtain the time point corresponding to the operation duration threshold of the current maintenance node;

Based on the time point and the preset time interval threshold, the maintenance time period corresponding to the current maintenance node is determined, and the service order within the maintenance time period is obtained.

Specifically, the preset time interval threshold may be set according to the type of the maintenance node. For work machines, maintenance nodes can be classified according to the number or difficulty of service items during maintenance. For example, it can be divided into small maintenance nodes (non-essential maintenance nodes) and large maintenance nodes (essential maintenance nodes). The service items of the large maintenance node are different from those of the small maintenance node.

小时；如果当前保养节点为小保养节点，则当前保养节点对应的预设时间间隔阈值可以为

小时。Taking the small maintenance node and the large maintenance node as an example, the operation duration threshold of the large maintenance node is T hours, and the operation duration threshold of the small maintenance node is t hours, where T>t. If the current maintenance node is a large maintenance node, the preset time interval threshold corresponding to the current maintenance node can be

hour; if the current maintenance node is a small maintenance node, the preset time interval threshold corresponding to the current maintenance node can be

Hour.

作业机械的控制器获取执行时间在该保养时间段内的服务订单，判断这些服务订单是否满足当前保养节点的保养需求。Taking the current maintenance node as a large maintenance node as an example, after determining that the current time point T ₀ is the time point corresponding to the operation duration threshold of the current maintenance node, it can be determined that the maintenance time period corresponding to the current maintenance node is:

The controller of the work machine acquires service orders whose execution time is within the maintenance time period, and determines whether these service orders meet the maintenance requirements of the current maintenance node.

Based on any of the above embodiments, the operation duration threshold of the current maintenance node is determined based on the following steps:

Obtain the current operating conditions of the operating machine and the standard required operating time of the current maintenance node;

Determine the operating time adjustment factor corresponding to the current operating condition;

Based on the operation duration adjustment coefficient and the standard required operation duration of the current maintenance node, the operation duration threshold of the current maintenance node is determined.

Specifically, the maintenance nodes of the work machine can also be dynamically changed as the working conditions of the work machine change. For example, for an excavator, the high oil temperature, high water temperature, high load and strong vibration of the crushing operation cause more serious losses to the excavator body than the excavation operation. Therefore, the current maintenance node can be shortened. The operating time threshold is adjusted accordingly, and the maintenance service items are adjusted according to the actual situation.

The standard required operating time of the operating machine at each maintenance node, and the operating time adjustment coefficient corresponding to each operating condition can be pre-stored in the controller of the operating machine. The standard required operation duration and the operation duration adjustment coefficient can also be obtained by manual input by the user. The controller of the working machine can obtain the current working condition through the user's manual input or sensor perception, and then determine the operation time adjustment coefficient corresponding to the current working condition. Adjust to obtain the operation duration threshold of the current maintenance node.

For example, 5 maintenance nodes can be set up for the excavator, and the standard required operation time of each maintenance node is 100 hours. The working conditions of the excavator include excavation working conditions, crushing working conditions, and leveling working conditions. Among them, the adjustment factor of the operation time corresponding to the excavation operation condition is 1, the adjustment factor of the operation time corresponding to the crushing operation condition is 0.8, and the adjustment factor of the operation time corresponding to the leveling operation condition is 1.2. When the excavator is in the crushing operation condition, the standard required operation duration of the current maintenance node can be multiplied by the operation duration adjustment coefficient corresponding to the crushing operation condition, and the operation duration threshold of the current maintenance node can be obtained as 80 hours.

Based on any of the above-mentioned embodiments, FIG. 2 is the second schematic flow chart of the method for reminding maintenance of a work machine provided by the present invention. As shown in FIG. 2 , the execution subject in the figure includes a controller of the work machine, an engineer terminal, a user terminal, and a work machine. Mechanical remote monitoring system. The main body that executes the working machine maintenance reminder method is the controller of the working machine.

After the controller of the work machine determines that the operation duration is greater than or equal to the operation duration threshold of the work machine at the current maintenance node, it triggers to enter the current maintenance node. If there is a service order that meets the maintenance requirements of the current maintenance node within the maintenance time period corresponding to the current maintenance node, there is no need to display the maintenance reminder information on the central control screen of the work machine; if there is no service that meets the maintenance requirements of the current maintenance node order, the maintenance reminder information will be displayed on the central control screen of the work machine.

The controller of the work machine sends maintenance requirements to the work machine remote monitoring system, and the work machine remote monitoring system generates a service order and assigns it to the engineer terminal. After the service engineer accepts the order, fills in the execution time and sends the service order to the work machine. Mechanical controller.

The user terminal can also create a service order by itself and send it to the engineer terminal. After the service engineer accepts the order, fill in the execution time and send the service order to the controller of the operating machine.

During construction work, the user terminal can also forcibly remove and display maintenance reminder information by sending a message removal instruction.

In particular, if the user is unwilling to perform maintenance on the work machine, the user terminal can also send a maintenance cancellation command to the engineer terminal, and after the service engineer confirms, the maintenance reminder message can be cleared and displayed.
