Also have abnormal show pattern 11a in liquid crystal display part 11, this abnormal show pattern 11a word and code notify the exception occurred in body 1.When reality occurs abnormal, as shown in the figure, not only abnormal show pattern 11a glimmers, and light emitting diode 12 also glimmers.
Represent the control circuit of remote control 10 in figure 3.
Imput output circuit 21 is connected between the line of transmission line 2.This imput output circuit 21 is by the terminals P 1, the P2 that are connected with transmission line 2, terminal N1, N2 of being connected with following receiving and transmitting part 22, the diode bridge being each other connected to these terminals is formed, even and if terminals P 1, P2 to be connected up any state connected in positive and negative state relative to transmission line 2, from this terminal N1, N2 output, DC voltage Va, terminal N1 are always positive side, terminal N2 is always minus side.
Via receiving and transmitting part 22, stabilized power supply circuit 23 is connected with terminal N1, N2 of this imput output circuit 21.Receiving and transmitting part 22 comprises: the unit DC voltage Va inputted from imput output circuit 21 being supplied to as it is stabilized power supply circuit 23; Extract the small voltage fluctuation being overlapped in the DC voltage Va inputted from imput output circuit 21, and be supplied to the unit of following micro controller unit (MCU) 30; By the connection between the line of transmission line 2 with close the unit information supplied from MCU 30 being sent to body 1.
Stabilized power supply circuit 23 DC voltage supplied from imput output circuit 21 is converted to the level of the action being applicable to remote control 10, DC voltage Vd after stable exporting.
On the other hand, the base of liquid crystal display drive circuit 31, operating portion 13, indoor temperature transmitter 32, NPN transistor 25 is connected with the MCU (micro controller unit) 30 of the control part as remote control 10.
And, via resistance 24, the positive side terminal of light emitting diode 12 is connected with the positive side terminal N1 of imput output circuit 21, and the minus side terminal of this light emitting diode 12 via transistor 25 collector emitter between and ground connection.
Liquid crystal display drive circuit 31 shows the information supplied from MCU 30 with liquid crystal display part 11.Indoor temperature transmitter 32 detection is placed with the indoor temperature in the place of remote control 10 and inputs to MCU 30.
And as major function, MCU 30 possesses the unit of following (1) ~ (5).
(1) start with action, generate the unit of control clock signal.
(2) fluctuate the small voltage extracted by receiving and transmitting part 22 unit obtained as the transmission signal from body 1.
(3) main processing units, it monitors above-mentioned acquisition, and just perform the process based on the information of this acquisition once obtaining information, and in the interrupt timing of the regulation of the counting based on above-mentioned clock signal, by the detected temperatures information of indoor temperature transmitter 32 or depend on that the set information of operation of operating portion 13 is sent to body 1 via receiving and transmitting part 22.
(4) indicative control unit, when above-mentioned obtained transmission signal represent any abnormal time, make the abnormal show pattern 11a flickering display of liquid crystal display part 11, and make light emitting diode 12 flickering display.
(5) above-mentioned indicative control unit make abnormal show pattern 11a carry out flickering display and light emitting diode 12 carry out flickering display time, make the increase of the current sinking produced due to this flickering display and reduction be less than regulation.
Specifically, each flickering display is controlled to: when liquid crystal display part 11 carries out flickering display and light emitting diode 12 carries out flickering display, the abnormal show pattern 11a of liquid crystal display part 11 repeats lighting and light-off in cycle T 1, light emitting diode 12 repeat with in above-mentioned cycle T 1, lighting that the lighting of abnormal show pattern 11a starts to match start and with in cycle T 1, light-off that the light-off of abnormal show pattern 11a terminates to match starts.
Then, the change of the control of the MCU 30 when obviously showing exception with reference to Fig. 4 and the DC voltage Va with this control.In addition, although with the step-like change representing DC voltage Va, this change is actually level and smooth.
The flickering display of the abnormal show pattern 11a of liquid crystal display part 11 repeats following process: in order to carry out lighting to abnormal show pattern 11a, open the process of the access to liquid crystal display drive circuit 31; In order to turn off the light to abnormal show pattern 11a, open the process of the access to liquid crystal display drive circuit 31.Thus, abnormal show pattern 11a repeats lighting and light-off in cycle T 1.
The flickering display of light emitting diode 12 repeats following process: in order to carry out lighting to light emitting diode 12, make the process of transistor 25 conducting; In order to turn off the light to light emitting diode 12, make the process that transistor 25 ends.
Thus, light emitting diode 12 repeat with in cycle T 1, lighting that the lighting of abnormal show pattern 11a starts to match starts (to liquid crystal drive portion 31 during lighting open access), and with in cycle T 1, the light-off of abnormal show pattern 11a terminates the light-off that (accessing the closedown of liquid crystal display drive circuit 31 during light-off) match and starts.This repetition period, T2 was identical with cycle T 1.
In addition, when for for carrying out lighting to abnormal show pattern 11a, the access of liquid crystal display drive circuit 31 of light-off be opened time, normal main process is closed, and when the access for liquid crystal display drive circuit 31 is closed, this mainly processes and is opened.
Owing to being opened the access of liquid crystal display drive circuit 31, electric current is consumed, but to be closed and compared with the current segment saved, this current sinking is less with because mainly processing.
The current sinking that produces because access is opened now is closed and the difference of current segment of saving with because mainly processing, about the same compared with the lighting because of light emitting diode 12 and the electric current that consumes.
Thus, even if light emitting diode 12 starts to match with the lighting of abnormal show pattern 11a and carries out lighting and starts, the increase of current sinking now and reduction, also in predetermined scope, are namely fully less than regulation, can not apply unwanted fluctuation to the DC voltage Va on transmission line 2.
To the access of the liquid crystal display drive circuit 31 for carrying out lighting to abnormal show pattern 11a open end after, light emitting diode 12 maintains lighting state, although now add current sinking owing to adding main to be processed opening, this increase part is in preset range (being less than regulation).
Now, the DC voltage Va on transmission line 2 reduces Δ V1, but this reduction part is than little for extracting the threshold value sending signal, and sending signal to extraction does not affect.
When opening for access to the liquid crystal display drive circuit 64 that abnormal show pattern 11a turns off the light in cycle T 1, light emitting diode 12 maintains lighting state, but main process is closed herein, therefore same as abovely, increase and the reduction of current sinking are fully less than regulation.Thus, unwanted fluctuation can not be applied to the DC voltage Va on transmission line 2.
Then, when the access to liquid crystal display drive circuit 31 when light emitting diode 12 is turned off the light with abnormal show pattern 11a is closed and is matched and turn off the light, current sinking only have main process, current sinking is to the change of reduction direction, but same as abovely, this reduction part is less than regulation, and the above-mentioned reduction part Δ V1 of the DC voltage Va in transmission line 2 is eliminated.
As mentioned above, even if carry out the flickering display of abnormal show pattern 11a and the flickering display of light emitting diode 12, also can not apply unwanted fluctuation to the DC voltage Va on transmission line 2, the transmission signal from body 1 can be obtained thus exactly.
In addition, the example that the increase of the current sinking produced by flickering display and reduction are not less than regulation is shown in Figure 5 as a reference.That is, light emitting diode 12 repeat with in cycle T 1, lighting that the lighting of abnormal show pattern 11a terminates to match starts, and with in cycle T 1, light-off that the light-off of abnormal show pattern 11a terminates to match starts.
In this case, owing to being opened the access of liquid crystal display drive circuit 31 when the 11a lighting of abnormal show pattern, electric current is consumed, but to be closed and compared with the current segment saved, this current sinking is less with because mainly processing.
Now, because light emitting diode 12 is in light-off state, therefore current sinking reduces, but this reduction part is less than regulation.With this reduction, the DC voltage Va on transmission line 2 increases Δ V1, but this increase part Δ V1 is than little for extracting the threshold value sending signal, and sending signal to extraction does not affect.
But when light emitting diode 12 terminates to match with the lighting of abnormal show pattern 11a and carries out lighting, main current drain to be processed is added to this lighting part, and therefore current sinking is to the change of increase direction.
It is the Δ V2 of 2 times of Δ V1 that the reduction part of DC voltage Va now becomes, and fluctuation is comparatively large, and this reduction part Δ V2 is than large for extracting the threshold value sending signal.Because this reduction part Δ V2 is acquired mistakenly as transmission signal, can the extraction sending signal be had an impact.
But, when the first embodiment, this problem can not be there is.
(the second embodiment)
In this second embodiment, in the major function of MCU 30, above-mentioned (5) abnormal show pattern 11a carries out flickering display and light emitting diode 12 when carrying out flickering display, and the control module making the increase of the current sinking produced due to this flickering display and reduction be less than regulation has following difference.
Specifically, difference is, when liquid crystal display part 11 carries out flickering display and light emitting diode 12 carries out flickering display, the abnormal show pattern 11a of liquid crystal display part 11 repeats lighting and light-off in cycle T 1, and in cycle T 1, being closed to the access of the liquid crystal display drive circuit 31 of abnormal show pattern 11a period, light emitting diode 12 repeats lighting to start and beginning of turning off the light.
Other structure is identical with the first embodiment, and therefore the description thereof will be omitted.
That is, as shown in Figure 6, owing to being opened the access of liquid crystal display drive circuit 31 when the 11a lighting of abnormal show pattern, electric current is consumed, but to be closed and compared with the current segment saved, this current sinking is less with because mainly processing.
Now, because light emitting diode 12 is in light-off state, therefore current sinking reduces, but this reduction part is less than regulation.With this reduction, the DC voltage Va on transmission line 2 increases Δ V1, but this increase part Δ V1 is than little for extracting the threshold value sending signal, and sending signal to extraction does not affect.
Then, during due to being closed the access of liquid crystal display drive circuit 31 at the end of the lighting of abnormal show pattern 11a, light emitting diode 12 is in light-off state, current sinking only have main process, to the change of increase direction, DC voltage Va reduces current sinking, but this reduction part is the Δ V1 less than the threshold value for extracting transmission signal, and sending signal to extraction does not affect.
And, when the access of the liquid crystal display drive circuit 31 to abnormal show pattern 11a is closed period, when light emitting diode 12 carries out lighting, to the change of increase direction, DC voltage Va reduces current sinking, but this reduction part is the Δ V1 less than the threshold value for extracting transmission signal, and sending signal to extraction does not affect.
Then, period is closed in the access of the liquid crystal display drive circuit 31 after terminating of turning off the light to abnormal show pattern 11a, light emitting diode 12 is turned off the light, to the change of reduction direction, DC voltage Va increases current sinking, but this increase part is the Δ V1 less than the threshold value for extracting transmission signal, and sending signal to extraction does not affect.
As mentioned above, even if carry out the flickering display of abnormal show pattern 11a and the flickering display of light emitting diode 12, also can not apply unwanted fluctuation to the DC voltage Va on transmission line 2, the transmission signal from body 1 can be obtained thus exactly.
(the 3rd embodiment)
3rd embodiment is the variant of the second embodiment, and the lighting of light emitting diode 12 is different with the cycle T 2 of light-off from the lighting of abnormal show pattern 11a with the cycle T 2 of light-off, but as shown in Figure 7, the different cycle.
Other structure, effect are identical with the second embodiment.
(the 4th embodiment)
As shown in Figure 8, the positive side lead-out terminal of stabilized power supply circuit 23 is connected with one end of current drain resistance 41, the another terminal of this resistance 41 via NPN transistor 42 collector-emitter between and ground connection, the base of transistor 42 is connected with MCU 30.
The current consuming unit forcing current sinking is formed by these resistance 41 and transistor 42.
Along with the employing of this current drain power supply, in the major function of MCU 30, above-mentioned (5) abnormal show pattern 11a carries out flickering display and light emitting diode 12 when carrying out flickering display, and the control module making the increase of the current sinking produced due to this flickering display and reduction be less than regulation has following difference.
Specifically, difference is, each flickering display is controlled to: when liquid crystal display part 11 carries out flickering display and light emitting diode 12 carries out flickering display, the abnormal show pattern 11a of liquid crystal display part 11 repeats lighting and light-off in cycle T 1, light emitting diode 12 repeats with above-mentioned cycle T 1, lighting that the lighting of abnormal show pattern 11a terminates to match starts and with cycle T 1, the light-off that the light-off of abnormal show pattern 11a terminates to match starts, and in the lighting of abnormal show pattern 11a, when light-off starts, make the conducting of above-mentioned transistor 42, and open the function of current consuming unit.
Other structure is identical with the first embodiment, and therefore the description thereof will be omitted.
That is, as shown in Figure 9, light emitting diode 12 repeat with in cycle T 1, lighting that the lighting of abnormal show pattern 11a terminates to match starts, and with in cycle T 1, light-off that the light-off of abnormal show pattern 11a terminates to match starts.
In this case, owing to being opened the access of liquid crystal display drive circuit 31 when the 11a lighting of abnormal show pattern, electric current is consumed, but to be closed and compared with the current segment saved, this current sinking is less with because mainly processing.
Because now light emitting diode 12 is in light-off state, although current sinking is to the change of reduction direction, transistor 42 conducting and electric current flow into resistance 41 makes this reduction part become as not existing.Because this impressed current consumes, unwanted fluctuation can not be applied to the DC voltage Va on transmission line 2.
Then, when light emitting diode 12 terminates to match with the lighting of abnormal show pattern 11a and carries out lighting, main current drain to be processed is added to this lighting part, and therefore current sinking is to the change of increase direction.Meanwhile, DC voltage Va reduces, but this reduction part is the Δ V less than the threshold value for extracting transmission signal, and sending signal to extraction does not affect.
(the 5th embodiment)
The difference of the 5th embodiment is, in the major function of MCU 30, using above-mentioned (5) as when abnormal show pattern 11a carries out flickering display and light emitting diode 12 carries out flickering display, make the control module that the timing of each flickering display is different with the timing of the flickering display in other remote control.
Other structure is identical with any one of first to fourth embodiment.
The effect of the 5th embodiment is described with reference to Figure 10.In addition, lighting and the light-off of light emitting diode 12 is only shown in Fig. 10, eliminates lighting and the light-off of abnormal show pattern 11a.The timing controlled of the flickering display of light emitting diode 12 and the flickering display of abnormal show pattern 11a is identical with any one of first to fourth embodiment.
In in the multiple remote controls 10 be connected with body 1, to be set to machine tool remote controls 10, in the regulation timing of the clock signal produced based on starting with action, start to carry out making light emitting diode 12 in cycle T x, repeat the control of lighting and light-off.
All the other are set in the remote control 10 of handset, the clock signal produced based on starting with action, in the timing of delay stipulated time compared with starting with the above-mentioned control of machine tool, start to control, make light emitting diode 12 repeat lighting and light-off at cycle T y.Cycle T y is identical with cycle T x.
When there is multiple handset, the mutual control of each handset starts timing and staggers successively.
By this structure, the fluctuation of DC voltage Va can be avoided to overlap along with the flickering display of each remote control 10, become large situation.Thus, in each remote control 10, the transmission signal from body 1 can be obtained exactly.
(the 6th embodiment)
6th embodiment is the variant of the 5th embodiment, and as shown in figure 11, the cycle T y of handset is different from the cycle T x of machine tool.
Other structure, effect are identical with the 5th embodiment.
