The CPU 31 of level detecting apparatus 30 by the testing result comprising vibrating detector 33 and determines when receiving confirmation signal
The information of cell voltage is replied as response signal.CPU 21 judges whether to receive response signal (S2).Receiving
(S2 before to response signal："No"), it is next standby that CPU 21 returns to S2.(the S2 when receiving response signal："Yes"), CPU
21 judge whether to detect the displacement (S3) of lathe 1 based on the response signal received.When detecting the displacement of lathe 1
(S3："Yes"), there is a possibility that a suspect is wrongly shifted to lathe 1, therefore CPU 21 limits lathe 1
Act (S7).The limitation of action for example refers to that the startup of lathe 1 stops, the driving of axle drive division stops, utilizing control panel 11
Operation stopping of progress etc..Therefore when wrongly having carried out displacement to lathe 1, lathe 1 can not be acted.CPU 21 will
The displacement detection mark stored in RAM 23 is set as 1 (S8) and terminates present treatment.When detecting the displacement of lathe 1, CPU
The action of 21 limitation lathes 1.CPU 21 is in the foremost of display part 12 display displacement warning picture 62 (reference picture 8).Therefore make
User can identify the reason for action of lathe 1 stops.
(the S3 when not detecting the displacement of lathe 1："No"), CPU 21 based on response signal judges whether that electricity occurs
Pond is used up (S4).Broken battery refer to cell voltage be can not drive the magnitude of voltage (Second Threshold) of shift detector 30 with
Under.(the S4 in no generation broken battery："No"), CPU 21 allows the action (S5) of lathe 1.Therefore user can be normal
Use lathe 1.The displacement detection mark stored in RAM 23 is set as 0 (S6) and terminates present treatment by CPU 21.
(the S4 in broken battery："Yes"), CPU 21 when detecting displacement in the same manner as limit the action (S7) of lathe 1.
If off power switch, then the power supply source of shift detector 30 switches to battery 34 from AC power 28.Work as generation
During broken battery, shift detector 30 can not drive, therefore can not detect the displacement of lathe 1.Therefore CPU 21 limits lathe 1
Action, to prevent lathe 1 from being acted in the state of shift detector 30 can not detect the displacement of lathe 1.CPU 21
The displacement detection mark stored in RAM 23 is set as 1 (S8) and terminates present treatment.
Reference picture 4 come illustrate releasing handle.(reference picture 3) is handled by action control in CPU 21 and has carried out lathe 1
During action limitation, lathe 1 is without action, therefore user can not use lathe 1.Therefore user entrusts Machine Manufacture business to come
Releasing action limitation.Machine Manufacture business notifies the releasing key needed for solution division operation to user.Carrying out the action of lathe 1
For example solution division operation is carried out in the state of limitation by inputting the releasing key of control panel 11.CPU 21 is receiving releasing
Removing program is read to perform present treatment from ROM 22 during the input of key.CPU 21 releases the action limitation (S11) of lathe 1.
The displacement detection mark stored in RAM 23 is initialized as 0 (S12) and terminates present treatment by CPU 21.
Reference picture 5, which carrys out account for voltage, reduces determination processing.Present treatment is the battery electricity for judging shift detector 30
The processing of the reduction of pressure.When switch on power switch when, CPU 21 every specified period from the read-out voltages of ROM 22 reduce judge journey
Sequence performs present treatment.The cycle for performing present treatment is, for example, 20msec, than the week for performing warning display control processing described later
Phase, (such as 30msec) was short.Whether CPU 21 judges cell voltage with reference to the response signal received from shift detector 30
For (S21) below first threshold.(the S21 when cell voltage is higher than first threshold："No"), broken battery occurs in a short time
Possibility it is low.Therefore the voltage stored in RAM 23 reduction mark is set as 0 (S22) and terminates present treatment by CPU 21.
(S21 when cell voltage is below first threshold："Yes"), cell voltage is in reduction state, therefore electricity occurs in a short time
The possibility that pond is used up is high.Therefore voltage reduction mark is set as 1 (S23) and terminates present treatment by CPU 21.
Reference picture 6 is handled to illustrate to alert display control.Present treatment is following processing：Detecting shift detector 30
Cell voltage reduction or lathe 1 displacement when, various warning pictures are shown in display part 12, thus notify user.
When switch on power switch when, CPU 21 every specified period (such as 30msec) from ROM 22 read warning display control program
Perform present treatment.
The flow of processing during to detecting that cell voltage reduces illustrates.CPU 21 judges the electricity stored in RAM 23
Whether the low mark of pressure drop is 1 (S31).(the S31 when voltage reduction is masked as 1："Yes"), cell voltage is in reduction state, because
This CPU 21 is being carried out for example " during shift detector battery altering in the column 40 (reference picture 7) on the top of display part 12
Phase ", such warning showed (S33).Displacement detection system 100 to user notice be shift detector 30 battery 34
Replacing period.
CPU 21 judges whether user operates control panel 11 (hereinafter referred to as panel operation) (S34).Without panel
(S34 during operation："No"), CPU 21 judges whether the state of no panel operation continue for more than ten minutes (S35).Without panel
The state of operation continue for (S35 at more than ten minutes："Yes"), CPU 21 observably shows in the central foremost of display part 12
Show warnings picture 61 (S37).Fig. 7 shows the dispaly state of display part 12, and warnings picture 61 is to cover manual bar
The mode of the front side of part setting screen 51 is shown up front.Manual condition setting screen 51 is the hand for setting each drive shaft
The picture of dynamic condition.Warnings picture 61 for example shows the warning of following (1)~(4).
(1) be shift detector 30 battery 34 replacing period.
(2) cell voltage of shift detector 30 is in reduction state.
(3) promptly the dry cell of the battery case of control cabinet side is all changed in the state of power switch connection.
(4) then it is possible to detect displacement if off power switch.
If user's disconnecting power switch under the lowered state of cell voltage, power supply source is from AC power
28 switch to battery 34, and broken battery easily occurs in a short time.When there occurs during broken battery, CPU 21 passes through above-mentioned dynamic
Make control process (reference picture 3) to limit the action of lathe 1 in the same manner as when detecting displacement.User has to entrust lathe
Manufacturer limits to release action, so as to labor intensive and time.Therefore CPU 21 shows (4) in warnings picture 61
Warning, thus, it is possible to prevent user's disconnecting power switch under the lowered state of cell voltage.The energy of displacement detection system 100
Enough actions for preventing from unnecessarily limiting lathe 1 in advance.CPU 21 terminates present treatment.
Such as 1 (S31 is masked as even if voltage drop is low："Yes") but state without panel operation be less than ten minutes (S34：
"No", S35："No") when, user is also possible to carry out panel operation again.Therefore CPU 21 eliminates warnings picture 61
(S36) and present treatment is terminated.In the present treatment performed after the next cycle, ten minutes are continue in the state without panel operation
(the S35 during above："Yes"), the possibility that user carries out panel operation at once is low, therefore CPU 21 is by warnings picture 61
It is shown in the foremost (S37) of display part 12.Therefore displacement detection system 100 can reliably notify displacement detection to user
The reduction of the cell voltage of device 30.
In the state of warnings picture 61 is shown, only the cell voltage of shift detector 30, which is in, reduces
State, therefore the use of the various settings of control panel 11 is effective.Such as in the reduction due to cell voltage and to hide
When covering the mode of manual condition setting screen 51 and showing warnings picture 61, user occasionally wants to set in manual condition
Manual condition is set in picture 51.In the present treatment performed after the next cycle, when having carried out panel operation by user
(S34："Yes"), CPU 21 eliminates warnings picture 61 (S36).Therefore CPU 21 shows whole manual bar in display part 12
Part setting screen 51, therefore user can set manual condition in manual condition setting screen 51.CPU 21 terminates this place
Reason.
Such as sometimes after warnings picture 61 has been eliminated due to panel operation user leaves very from lathe 1
It is more than clock.User is likely due to lathe 1 away from keyboard and forgets cell voltage and be in reduction state.Without panel operation
State continue for (S35 at more than ten minutes："Yes"), CPU 21 shows warnings picture 61 again in display part 12
(S37).User can reaffirm the warnings picture 61 shown in display part 12, therefore energy after returning to Work places
Enough avoid carrying out battery altering with forgeing.That is, when cell voltage is in reduction state, whenever the state without panel operation continues
More than ten minutes, CPU 21 just showed warnings picture 61 repeatedly in display part 12, therefore can be to user reliably
Notify the reduction of cell voltage.CPU 21 terminates present treatment.
(the S31 when voltage reduction is masked as 0："No"), cell voltage is sufficient, therefore CPU 21 judges displacement detection mark
Whether it is 1 (S32).(the S32 when displacement detection is masked as 1："Yes"), due to detecting the displacement of lathe 1, therefore CPU 21 exists
Carry out for example " detecting displacement " that such warning shows (S38) in the column 40 on the top of display part 12, to user
Notice detects the displacement (reference picture 8) of lathe 1.
CPU 21 judges whether user has carried out panel operation (S39) to control panel 11.When without panel operation
(S39："No"), CPU 21 judges whether the state of no panel operation continue for more than ten minutes (S40).Without panel operation
State continue for (S40 at more than ten minutes："Yes"), foremost display displacement warning pictures of the CPU 21 in the center of display part 12
62 (S41) simultaneously terminate present treatment.Fig. 8 shows the dispaly state of display part 12, and displacement alerts picture 62 to cover manual condition
The mode of the front side of setting screen 51 is shown.Displacement warning picture 62 for example shows the warning of following (1) and (2).
(1) shift detector 30 detects the displacement of lathe 1.
(2) in order to release action limitation, lathe manufacturer is got in touch with.
CPU 21 reliably notifies user to detect the displacement of lathe 1, therefore user can readily recognize machine
The reason for bed 1 is acted by limitation.
Such as it is masked as 1 (S32 in displacement detection："Yes") and after having carried out in the column 40 of display part 12 warning display
(S38) (the S39 when state without panel operation is less than ten minutes："No", S40："No"), CPU 21 eliminates displacement warning picture 62
(S42) and present treatment is terminated.In the present treatment performed after the next cycle, ten minutes are continue in the state without panel operation
(the S39 during above："No", S40："Yes"), CPU 21 shows displacement warning picture 62 (S41) in display part 12.Therefore shift
Detecting system 100 can reliably notify user to detect the displacement of lathe 1.
The use of the various settings of control panel 11 is effective in the state of displacement warning picture 62 is shown.When
Show (S39 when having carried out panel operation by user in the state of displacement warning picture 62："Yes"), CPU 21 eliminates displacement
Alert picture 62 (S42).CPU 21 shows whole manual condition setting screen 51, therefore user can set in manual condition
Manual condition is set in picture 51.CPU 21 terminates present treatment.
Such as sometimes eliminated due to panel operation displacement warning picture 62 after user left very from lathe 1
It is more than clock.User is likely due to lathe 1 away from keyboard and forgets to detect the displacement of lathe 1.When the shape without panel operation
State continue for (S40 at more than ten minutes："Yes"), CPU 21 shows displacement warning picture 62 (S41) again in display part 12.
User can reaffirm the displacement warning picture 62 shown in display part 12 after returning to Work places.Therefore user's energy
Enough carry out getting in touch with the rapidly reply such as lathe manufacturer, to release the action of lathe 1 limitation.CPU 21 terminates present treatment.
As described above, in the warning display control processing shown in Fig. 6, CPU 21 is judging whether voltage reduces mark
After 1 (S31), judge whether displacement detection mark is 1 (S32).That is, CPU 21 is first true before the displacement of lathe 1 is confirmed
Recognize the reduction of cell voltage.Therefore when the displacement and the reduction of the cell voltage of shift detector 30 that are detected simultaneously by lathe 1
When, CPU 21 limits the action of lathe 1, and is reduced based on voltage and be masked as 1 to show that warnings are drawn in display part 12
Face 61.
Displacement detection system 100 can reliably promote user to carry out battery altering, therefore can prevent in releasing machine
Broken battery occurs so as to limit the situation of the action of lathe 1 again after the action limitation of bed 1.
Machine Manufacture business is entrusted in user to have carried out the battery of shift detector 30 more before releasing action limitation
When changing, in the voltage shown in Fig. 5 reduces determination processing, cell voltage exceedes first threshold (S21："No"), therefore CPU 21
Voltage reduction mark is set as 0 (S22).In the warning display control processing shown in Fig. 6, voltage reduces and is masked as 0 (S31：
"No"), but displacement detection is masked as 1 (S32："Yes").Therefore CPU 21 carries out " detecting shifting in the column 40 of display part 12
The such warning in position " shows (S38), (S40 when the state without panel operation continue for more than ten minutes："Yes"), display moves
Position warning picture 62 (S41).Therefore user can identify the reason for lathe 1 is acted by limitation.Due to shift detector 30
Cell voltage it is sufficient, therefore displacement detection system 100 can prevent that displacement detection fills after the action limitation of lathe 1 is released
30 generation broken batteries are put so as to limit the situation of the action of lathe 1 again.
In the above description, Fig. 1 shift detector 30 is one of displacement detection portion of the present invention.Lathe 1 is this
Mechanical one of invention.The CPU 21 for performing S3 judgement processing is one of the displacement determination unit of the present invention.Perform S4's
