Monitor the low state with heat controller of oil temperature.
The information of control device 42 is obtained as operation information, deck crane system by operation conditions detection device 44
100 are not provided with new sensor, so that it may obtain the information that can more accurately grasp the operation conditions of deck crane 1.This
Outside, acquisition of information that unit detects will test as operation information, deck crane system by operation conditions detection device 44
The information for the 100 available operation conditions that can more accurately grasp deck crane 1 of uniting.
Particularly, deck crane system 100 can detecte electronic by the current value of acquisition main motor by acquisition
Whether machine is in the working condition of the main motor of overload, and can detecte the starting point of trouble hunting, (whether motor itself
Fault-free).By obtain alarm buzzer movement, can remotely be monitored in fault state confirmation.Pass through detection
Input operation to operating unit, can grasp the cargo handling period.The temperature in the hydraulic oil of hydraulic circuit is flowed by detection
Degree, can grasp the associated safety device fault state of oil temperature.
Then, using Fig. 5 to Fig. 8, illustrate the movement of deck crane system.Fig. 5 indicates deck crane system
The flow chart of an example of control.Fig. 5 indicates the processing of the record of the operation information detected by operation conditions detection device 44
An example.Operation conditions detection device 44 executes processing shown in fig. 5 repeatedly.
Operation conditions detection device 44 obtains health data (various operation informations) (step S12).Operation conditions inspection
Device 44 is surveyed to be stored in health data as the 1st data in storage device 46 (step S14).Storing the 1st data
Afterwards, whether operation conditions detection device 44 determines the data volume of the 1st data more than threshold value (step S16).Here, pair of judgement
The data volume of elephant is the amount for last time generating the data accumulated after the 2nd data.It is set as data volume in the present embodiment, but can also be with
Determined based on the time.In the case where being determined as the data volume of the 1st data not more than threshold value (being "No" in step S16),
Operation conditions detection device 44 proceeds to step S20.(the step in the case where being determined as that the data volume of the 1st data is threshold value or more
It is "Yes" in S16), operation conditions detection device 44 handles health data, generates the 2nd data, stores it in
In storage device (step S18), step S20 is proceeded to.
Then, operation conditions detection device 44 determines whether output data (step S20).Such as detecting the defeated of data
In the case where indicating out, or meets preset condition (the case where accumulation of data has been more than threshold value generates number every time
According to) in the case where, operation conditions detection device 44 is determined as output data.(the step in the case where being determined as not output data
It is "No" in S20), operation conditions detection device 44 terminates present treatment.
In the case where being determined as output data (being "Yes" in step S20), operation conditions detection device 44 is filled from storage
The 1st data of 46 reading are set, are written in the recording medium of recording medium processing unit (step S22), are read from storage device 46
2nd data export (step S24) by communication unit.Furthermore operation conditions detection device 44 also can be made whether to execute step
Each step of S22 and step S24 only carries out the processing of a side based on judgement result.
As shown in figure 5, the 1st more data of information content are recorded in record and are situated between by generating the 1st data and the 2nd data
In matter, 2nd data less from communication unit output information amount, deck crane system 100 can inhibit to increase the negative of communication
It carries, and information is sent to processing unit 106, but also the information for being able to carry out analysis with high accuracy can be accumulated.
Fig. 6 is the flow chart for indicating an example of control of deck crane system.Fig. 6 is indicated by operation conditions detection device
The processing that 44 self diagnosis processing unit 64 executes.Self diagnosis processing unit 64 determines whether there is the finger of self diagnosis mode
Show (step S30).The instruction of self diagnosis mode can be inputted from operating unit, can be based on preset condition from control
Device 42 exports, and can also export from the other parts of operation conditions detection device 44.
In the case where being determined as instruction (being "No" in step S30) of no self diagnosis mode, self diagnosis processing
Unit 64 returns to step S30.In the case where being judged to having the instruction of self diagnosis mode (being "Yes" in step S30), from
Body diagnostic process unit 64 notifies the processing (step S32) executed based on self diagnosis mode.Information of the driver based on notice
Operating unit 28 is operated, deck crane 1 is run.Self diagnosis processing unit 64 detects the first executed by driver
Movement (operation information) (step S34) in the self diagnosis mode of plate crane 1.
Then, self diagnosis processing unit 64 determines whether the movement of self diagnosis mode terminates (step S36).Determining
For (being "No" in step S36) in the unclosed situation of movement of self diagnosis mode, self diagnosis processing unit 64 is returned to
Step S32 executes the processing of step S32, step S34.That is, the movement of notice self diagnosis mode is repeated, acquisition passes through
Execute the processing for the movement operation information detected being performed.In the case where being determined as that the movement of self diagnosis mode terminates

It is enough that the service life is determined with higher precision.
Fig. 8 is the flow chart for indicating an example of control of deck crane system.Fig. 8 shows the long-range of processing unit 106
An example of the processing of monitoring unit 126.
Remote monitoring unit 126 obtains health data (step S62).Remote monitoring unit 126 is from operation conditions number
According to the data (step S64) of middle extraction and analysis object.Remote monitoring unit 126 is set the fault message with deck crane 1
The type of the corresponding operation information used.Based on setting, the extraction and analysis object from health data of remote monitoring unit 126
Data.Remote monitoring unit 126 can be from operation direction, raising driving pressure, pitching and the situation for rotating driving pressure, prison
Decline situation depending on pump performance.In addition, remote monitoring unit 126 can be from the operation direction of each movement, driving pressure, speed
Degree, the performance decline of monitoring motor and the setting value of overflow valve are qualified or not.In addition, remote monitoring unit 126 can from oil temperature,
Pitching and rotation driving pressure, the low state with heat controller of monitoring oil temperature.Remote monitoring unit 126 is after extracting data, base
Data (step S66) in the data extracted, when data and failure when more usual.Remote monitoring unit 126 be based on than
Compared with as a result, carrying out the estimation (step S68) of trouble location.Remote monitoring unit 126 is led to after the estimation for carrying out trouble location
Know estimated result (step S70).Remote monitoring unit 126 can notify the driver of deck crane 1 by communication unit,
It can be with the operator of notifier processes device 106.
Deck crane system 100 is by estimating failure portion based on the information detected by operation conditions detection device 44
Position, can with higher precision determine failure the reason of.
