Description

  The present invention relates to an apparatus that can provide an operator with guidance on operation in a transmission / reception system for a construction machine.

  Construction machines such as hydraulic excavators vary greatly in fuel consumption due to differences in the operator's individual operation capabilities and skills.

  Also, the construction machine operates continuously for a long time once the engine is started by the operator. For example, when the engine is started in the morning, it runs continuously until the evening, except for a brief pause during the lunch break. In such usage peculiar to construction machines, the amount of fuel consumed per day varies greatly depending on the operator's ability and skill, and the fuel cost varies greatly. For this reason, as an administrator who manages the operator, it is an important issue to give guidance and guidance to the operator so as to keep the fuel consumption as small as possible whenever the operator operates the construction machine.

(Practical technique 1 in the past)
In the field of construction machinery, a transmission / reception system for transmitting / receiving data between a plurality of construction machinery and ground stations existing at various positions on the earth has already been introduced. In this transmission / reception system, the internal information captured from the in-vehicle controller is transmitted to the ground station via the in-vehicle network of each construction machine of the plurality of construction machines, and the internal information of the plurality of construction machines is received by the ground station. Then, data is transmitted from the ground station to each construction machine according to the processing result, and each construction machine performs processing based on the received data.

(Practical technique 2 in the past)
In the field of construction machinery, a single construction machine is operated by a plurality of operators, and conversely, a single operator operates a plurality of construction machines. Therefore, each operator often owns an engine key individually, and the engine key owned by the operator corresponds to the engine start of a plurality of construction machines.

(Prior art found in patent literature)
Patent Document 1 describes an invention of managing fuel consumption for the purpose of determining whether a vehicle is in good condition in the field of general automobiles. That is, in Patent Document 1, the fuel consumption amount is recorded for each user in one automobile, and the maintenance state of the automobile is compared with the past average fuel consumption of the user and the recent average fuel consumption each time the user drives. An invention for judging whether the quality is good or bad is described.
JP 2002-166999 A

  The invention described in Patent Document 1 manages the fuel consumption for the purpose of judging whether the maintenance state of the automobile is good or not. The fuel consumption of the individual operator is not necessarily the objective reference value. In comparison, it does not judge whether the operator's individual driving ability and skill are good or bad. In other words, in Patent Document 1, the comparison object compared with the recent fuel consumption amount of the user is the past fuel consumption amount of the user himself and not an objective reference value.

  Further, in Patent Document 1, it is assumed that a plurality of users drive and operate a single car, but it is assumed that a plurality of cars are driven and operated by a single key owned by the user. Not.

  In addition, existing transmission / reception systems in the field of construction machinery are premised on sending data from the ground station to the construction machinery by communication. Therefore, as an administrator, every time the operator operates the construction machine, the data for instructing and guiding the operator to minimize the fuel consumption is sent from the ground station side to the construction machine side by communication. Can be considered.

  However, if the operator sends necessary data to a large number of construction machines around the world each time the operation is changed, there is a possibility that a communication load increases. In addition, when the communication status is not good, it becomes difficult to send the data itself from the ground station to the construction machine.

a) The present invention has been made in view of such circumstances, and avoids an increase in communication load and reliably guides and guides an operator in the vehicle body of a construction machine even in a situation where the communication condition is not good. It is an object to be able to capture data for the purpose.

b) In addition, the present invention is to construct a system suitable for usage in which a plurality of operators operate a single construction machine and, conversely, a single operator operates a plurality of construction machines. Is an issue.

The second invention is the first invention,
The operation result is information on fuel consumption.

The third invention is

A fourth invention is the first invention,
The display is performed on a display screen of a portable terminal device.

The fifth invention is the second invention,
The display device displays the current fuel consumption information together.

In the first invention, as shown in FIG. 5, when the operator performs a key-on operation on the key means 50 (YES in Step 201), the key side communication unit 52 of the key means 50 and the vehicle body side communication part 22 of the in-vehicle controller 20. Can be transmitted / received to / from each other via the in-vehicle network 15.

Therefore, the authentication control unit 23 of the in-vehicle controller 20 takes in and registers the operator identification ID stored in the operator identification ID storage unit 51 of the key means 50 via the vehicle body side communication unit 22 in response to a key-on operation. It is verified that the two match with the operator identification ID (step 202).

When authentication is performed by the authentication control unit 23, the first vehicle body side writing control unit 25 sends a construction machine identification ID for identifying its own construction machine 1 to the in-vehicle network 15 via the vehicle body side communication unit 22. . As a result, the key-side read control unit 54 of the key means 50 takes in the construction machine identification ID, reads the past operation result corresponding to the construction machine identification ID from the key-side operation result storage unit 53, and causes the key-side communication unit 52 to Via the network 15 in the vehicle body. As a result, the first vehicle body side write control unit 25 takes in the past operation results corresponding to the construction machine identification ID read by the key side read control unit 54, and the first vehicle body side operation result storage unit 24. Is written as a past operation result of its own construction machine 1 (step 203). Here, the “operation result” is the result of the operator operating the construction machine 1 such as information on the fuel consumption, the time and number of times the work machine has been operated, the engine rotation speed during work, and the engine use torque during work. Any information can be selected as long as the information is obtained. In the second invention, the operation result is information on the fuel consumption.

When the authentication control unit 23 authenticates, the engine control unit 26 permits the engine 3 to start. That is, when the key means 50 performs an engine start operation for starting the engine, the starter motor 4 is operated and the engine 3 is started on the condition that the authentication has been made (the determination of step 202 is YES) ( Step 204).

The first vehicle body side operation result storage unit 24 stores the past operation results of the construction machine stored in the key side operation result storage unit 53 and stores the ground station side operation result of the ground station 160. The past operation results of the plurality of construction machines 1, 1, 1,... Stored in the unit 61 are stored. Therefore, while the operator is operating the construction machine 1, the display control unit 27 causes the display device 40 to display past operation results in the construction machine 1 stored in the first vehicle body side operation result storage unit 24. Therefore, the operator can accurately determine whether the operator's individual driving operation ability and skill are good or bad by comparing the operator's individual driving operation result with an objective reference value. On the other hand, as an operator who manages the construction machine 1, every time the operator operates the construction machine 1, the operator can be instructed and guided accurately so as to keep the fuel consumption as small as possible. The display device 40 may also display current fuel consumption information (see FIG. 3; fifth invention).

The above-mentioned display may be performed on the display screen 40a of the display device 40 provided in the cab 2a of the construction machine 1 (see FIG. 1; the third invention), and the display screen of a portable terminal device (for example, a mobile phone) A similar display may be performed on the display screen (fourth invention) (step 207).

While the engine is running, the operation result measurement unit 21 measures the operation result. In the second vehicle body side operation result storage unit 28, the operation results measured by the operation result measuring unit 21 from when the engine 3 is started to when the operation of the engine 3 is stopped are newly stored in the construction machine 1 of its own. The operation result is stored in association with its own construction machine identification ID (steps 205 and 206).

In response to the key-off operation (step 208), the first vehicle body side readout control unit 29 reads out a new operation result in the own construction machine 1 stored in the second vehicle body side operation result storage unit 28. The operation result is sent to the in-vehicle network 15 via the vehicle body side communication unit 22 in association with the own construction machine identification ID. As a result, the key-side write control unit 55 of the key means 50 takes in a new operation result associated with the construction machine identification ID via the key-side communication unit 52, and based on the fetched new operation result, the key-side operation result. The operation result of the corresponding part of the storage unit 53 is updated. As described above, in the key means 50 owned by the operator, every time the construction machine 1 is operated, data on past operation results of the construction machine 1 is updated. The same applies when the same operator operates the other construction machines 1, 1,. In the key means 50 owned by the operator, the past operation result data is updated for each construction machine 1, 1, 1,... Each time the construction machine 1, 1, 1,. 4 (b); step 209).

On the other hand, as shown in FIG. 6, the second vehicle body side writing control unit 30 transmits / receives to / from the ground station 160 (step 301), thereby a plurality of construction machines stored in the ground station side operation result storage unit 61. The past operation results of 1, 1, 1,... Are taken into the vehicle body 2 and written into the first operation result storage unit 24 (step 302).

In addition, the second vehicle body side read control unit 31 transmits and receives to / from the ground station 160 (step 301), so that a new operation result in the own construction machine stored in the second vehicle body side operation result storage unit 28 is stored. Is transmitted to the ground station side operation result storage unit 61 by transmitting / receiving to / from the ground station 160 (step 304). As a result, the past operation result data of the plurality of construction machines 1, 1, 1... Stored in the individual construction machines 1 is the latest data acquired by many construction machines 1, 1, 1. Data of past operation results of a plurality of construction machines 1, 1, 1,... Stored in the ground station side operation result storage unit 61 of the ground station 160 is also acquired by each construction machine 1 while being updated by data. Updated with the latest data.

As described above, according to the present invention, the following effects can be obtained.

a) By transmitting and receiving between the key means 50 and the vehicle body 2 of the construction machine 1, data for guiding and guiding the operator can be taken into the vehicle body 2 of the construction machine 1. Therefore, it is not always necessary to transmit / receive data between the construction machine 1 and the ground station 160 to take in the data in the ground station 160 to the construction machine 1 side every time the operator operates.

Therefore, transmission / reception between the ground station 160 and the construction machine 1 is avoided every time the operator performs a driving operation, thereby preventing an increase in communication load. In addition, even in a situation where the communication status is not good, it is possible to reliably capture data for instructing and guiding the operator in the vehicle body 2 of the construction machine 1.

b) Each time the operator operates each construction machine 1, 1, 1... in the key means 50 owned by each individual operator, data of past operation results is updated for each type of construction machine 1. For this reason, a system suitable for usage is constructed in which a plurality of operators operate one construction machine 1, and conversely, one operator operates a plurality of construction machines 1, 1, 1,. can do.

c) The operator's individual driving results (eg average fuel consumption) can be compared with objective reference values (average fuel consumption obtained by a large number of construction machines 1, 1, 1,... around the world). It becomes possible to accurately determine whether the operator's individual driving operation ability and skill are good or bad.

d) On the ground station 160 side, information on fuel consumption for each user is stored together with information on fuel consumption for the entire world and information on fuel consumption for each country (FIG. 4). (Refer to (a)), by accessing the server 161 of the ground station 160 from the terminal 80, the fuel consumption information can be displayed on the screen of the terminal 80. For this reason, the president of the user's manager can compare, for example, the average fuel consumption of construction machinery owned by his company with the average fuel consumption of the world or the average fuel consumption of Japan. As a result, it is possible to accurately instruct all operators under the user's control to improve fuel consumption. Note that the fuel consumption information may be classified and stored for each operator on the ground station 160 side. As a result, the president of the user's manager can compare, for example, the average fuel consumption of construction machinery owned by his company with the average fuel consumption of the world and the average fuel consumption of Japan for each individual operator. Can do. As a result, it is possible to accurately provide guidance for improving the fuel efficiency for each operator under the control of the user.

First, the consumption amount ΔL (unit: liter L) of fuel injected into the cylinder of the engine 3 is measured per unit time ΔT. The unit time ΔT is, for example, 1 second. The fuel consumption amount ΔL per unit time ΔT is referred to as an instantaneous fuel consumption amount ΔL / ΔT. Further, the cumulative value of the fuel consumption amount ΔL per unit time ΔT is referred to as a cumulative fuel consumption amount SL (unit is liter L). The accumulated fuel consumption SL is obtained by multiplying the integrated value of the instantaneous fuel consumption ΔL / ΔT by the time T required for the fuel consumption, as in the following equation.

SL = (ΔL / ΔT + ΔL / ΔT + ΔL / ΔT +...) × T (1)
In addition, the time average value of the accumulated fuel consumption SL and the value converted to the unit of liter L / hour H is referred to as an average fuel consumption ΔLa.

  FIG. 4A shows the contents of data stored in the ground station side operation result storage unit 61.

As shown in FIG. 4A, the ground station side operation result storage unit 61 is created based on the internal information DT of the plurality of construction machines 1, 1, 1,. The ground station side operation result storage unit 61 stores data of an average fuel consumption ΔLa (unit: liter L / hour H) of a plurality of construction machines 1, 1, 1,.

The average fuel consumption ΔLa is classified and stored for each type (model, model) of the construction machine 1. Further, the average fuel consumption ΔLa is calculated for each type of construction machine 1 in the world, for each type of construction machine 1 in each country (Japan, USA, etc.), and for each type of construction machine 1 owned by each user. Are classified and stored. The type of construction machine 1 is specified by the model and type. For example, the excavator can specify the type of the construction machine 1 by the combination of the model “PC200” and the model “8”, that is, the content of data “PC200-8”. Similarly, the type of the construction machine 1 is specified by combining each model and model of “PC220-8”, “PC400-7”, “D155-5”, “LW250M-5”, “WA380-5”. Is done. “The average fuel consumption ΔLa for each type of construction machine 1 in the world” is, for example, “PC200-8” in the world of the same type (“PC200-8”) if the construction machine 1 is “PC200-8”. It is the average fuel consumption ΔLa (for example, 11.3 (L / H)) for a large number of construction machines 1, 1, 1,. Similarly, the “average fuel consumption ΔLa for each type of construction machine 1 in each country” is, for example, the construction machine 1 “PC200-8”. If the country is Japan, the same type (“PC200-8”) Is the average fuel consumption ΔLa (for example, 11.7 (L / H)) for a large number of construction machines 1, 1, 1,. Similarly, the “average fuel consumption ΔLa for each type of construction machine 1 owned by each user” is, for example, the construction machine 1 “PC200-8”, and the user is “CDE Civil Engineering Co., Ltd.” An average fuel consumption ΔLa (for example, 12.8 (L / H) when each operator operates the construction machine 1 of the same type (“PC200-8”) owned by the user (“CDE Civil Engineering Co., Ltd.”)). )).

Each construction machine 1 is specified by a combination of the type of construction machine 1 and the production number. For example, if the type of the construction machine 1 is “PC200-8” and the production number is “123”, the construction machine 1 can be specified by the data “PC200-8-123” of the combination thereof. In this specification, a code that is composed of a combination of the type and serial number of the construction machine 1 and that can identify each construction machine 1 and identify it from other construction machines 1 is called a construction machine identification ID in this specification. To do. For example, if the construction machine 1 is “PC200-8-123”, the contents of the construction machine identification ID of the construction machine 1 will be described as “PC200-8-123”.

Further, in the present specification, it is assumed that each operator owns the key means 50 individually. Therefore, a code that identifies the individual operator and the key means 50 themselves and can be identified from the other operators and the other key means 50 is referred to as an operator identification ID. For example, if the operator is “A mountain B Taro”, the operator and the operator identification ID of the key means 50 owned by the operator will be described as “A mountain B Taro”. In the following, the operator “A mountain B Taro” is an operator under the control of the user “CDE Civil Engineering Co., Ltd.”, and the construction machine 1 “PC200-8-123” is set to “X month Y day”. A description will be given assuming that the vehicle is operated.

On the other hand, FIG. 4B shows the contents of data stored in the key side operation result storage unit 53 of the key means 50.

The key-side operation result storage unit 53 stores information on past fuel consumption of each construction machine 1, 1, 1,... Operated by an operator (“A mountain B Taro”) specified by the operator identification ID. ing. Each construction machine 1, 1, 1,... Is a construction machine 1, 1, 1,... ("PC200-8-123", "PC220-8-124", "PC400" owned by the user "CDE Civil Engineering Co., Ltd."). -7-125 "," D155-5-126 "," LW250M-5-127 "," WA380-5-128 "). The information on the fuel consumption is the cumulative engine operation time SMR (unit H) and the cumulative fuel consumption SL (unit L). For example, the operator (“A mountain B Taro”) identified by the operator identification ID has been on the construction machine 1 “PC200-8-123” in the past for “230” hours, and the accumulated fuel in that boarding time. Data indicating that the consumption SL is “2346” liters is stored. Hereinafter, the cumulative engine operating time SMR and the cumulative fuel consumption SL stored on the key means 50 side will be described as “Skey” and “Nkey” for convenience of explanation of the control algorithm described later.

Hereinafter, the processing procedure in the present embodiment will be described with reference to the flowcharts shown in FIGS.

As shown in FIG. 5, when the operator performs a key-on operation on the key means 50 (see FIG. 2, determination of step 201), the key side communication unit 52 of the key means 50 and the vehicle body side communication part 22 of the engine controller 20A are connected. A state in which transmission and reception are possible via the in-vehicle network 15 is established.

Therefore, the authentication control unit 23 of the in-vehicle controller 20 responds to the key-on operation by using the operator identification ID (“A mountain B Taro” stored in the operator identification ID storage unit 51 of the key means 50 via the vehicle body side communication unit 22. ”) And is compared with the operator identification ID (“ A mountain B Taro ”) registered on the vehicle body 2 side to authenticate that they match (step 202).

When authentication is performed by the authentication control unit 23 (YES in Step 202), the first vehicle body side writing control unit 25 identifies the construction machine identification ID ("PC200-8-123") that identifies the construction machine 1 of its own. Is transmitted to the in-vehicle network 15 via the vehicle body side communication unit 22. As a result, the key-side read control unit 54 of the key means 50 takes in the construction machine identification ID, and stores the past accumulated engine operating time Skey and the accumulated fuel consumption Nkey corresponding to the construction machine identification ID on the key-side operation result storage unit 53. (See FIG. 4B) and sent to the in-vehicle network 15 via the key side communication unit 52.

(See FIG. 2; YES in Step 204).

While the engine is running, the operation result measuring unit 21 measures the instantaneous fuel consumption ΔL / ΔT. Then, the arithmetic processing of the above equation (1) is performed every unit time ΔT. Thereby, the content of the new accumulated fuel consumption amount Ntmp is updated every unit time ΔT as shown in the following equation (2).

Ntmp + (ΔL / ΔT × ΔT) → Ntmp (2)

-Average fuel consumption ΔLa (“Average fuel consumption in Japan”; for example, 11.7 L / H) of construction machinery 1 in Japan (“PC200-8”)
-Past average charge consumption ΔLa (“average fuel consumption so far”; for example, 10.2 L / H) of construction machine 1 (“PC200-8-123”) operated by “A mountain B Taro”
This is obtained by dividing the past cumulative fuel consumption Nkey by the past cumulative engine operating time Skey.

-Past cumulative engine operation time Skey of construction machine 1 ("PC200-8-123") operated by "A mountain B Taro"("cumulative operation time so far": 230H)
On the other hand, in the second vehicle body side operation result storage unit 28, the new accumulated fuel consumption amount Ntmp after the engine 3 is started, and the new accumulated engine operating time Ctmp after the engine 3 is started (2 ) And (3) are obtained by calculation and stored. As shown below, fuel consumption information is obtained from the data stored in the second vehicle body side operation result storage unit 28.

Then, as shown in the following equation (4), by performing an addition operation, based on the new accumulated engine operating time Ctmp and the new accumulated fuel consumption amount Ntmp that have been taken in, the fuel consumption at the corresponding location in the key-side operation result storage unit 53 is calculated. Quantity information, that is, “PC200-8-123” operated by “A mountain B Taro”
The past accumulated engine operating time Skey and the past accumulated fuel consumption Nkey (see FIG. 4B) are updated.

Nkey + Ntmp → Nkey
Sky + Ctmp → Sky (4)
