Abstract
A transmission unit and setting apparatuses include respective superimposition modules that use a superimposed signal, which is superimposed on a transmitted signal, to communicate with each other. The superimposition modules use the superimposed signal to transfer, from the setting apparatuses to the transmission unit, setting information to be used for group control and pattern control. The superimposition modules also utilize, for superimposition of the superimposed signal, as a conditionally superimposable band, a reply band in addition to three bands, i.e., an auxiliary interrupt band, an auxiliary band and an inactive band of the transmitted signal. That is, the superimposition modules use a determining unit to determine, for each of a plurality of frames of the transmitted signal, whether there exist any reply signals for a predetermined detection time period after a starting time point of the reply band. The superimposition modules then use, as a superimposable band, a reply band for which it is determined that there exist no reply signals.

embodiment 1
As shown in Figure 1A, according to the communication system of the present embodiment, comprise: as the transmission unit 1 of machine tool, it is connected to the communication line 2 of 2 line formulas; Many (being in this case 2) terminal installations 3; Many (being in this case 2) setting devices 4; And server unit 5.
In this communication system, utilize and comprise that two kinds of signals that transfer to the signal transmission (signal of the first agreement) of communication line 2 and be superimposed upon the different agreement of the superposed signal (signal of second protocol) on this signal transmission communicate.It is higher that superposed signal and signal transmission are compared frequency.
Many station terminals device 3 connects via communication line 2 side by side with respect to transmission unit 1.Transmission unit 1 and many station terminals device 3 form time division multiplexing transmission system (hereinafter referred to as " fundamental system "), wherein, in this time division multiplexing transmission system, while utilizing, assign to carry out transfer of data and the transfer of data from many station terminals device 3 towards transmission unit 1 from transmission unit 1 towards many station terminals device 3.
In this fundamental system, many station terminals device 3 is classified into following these two kinds of terminal installations: be equipped with the monitoring terminal such as the switch 31 of Wall-type switch etc.; The control terminal such as the controlled device 32 of repeater etc. is equipped with and.Therefore, can to being connected to the load (not shown) of controlled device 32, control in response to the supervision input from switch 31.In this case, each terminal installation 3 is stored in pre-assigned its oneself address in memory (not shown).Here, the assembly that monitoring terminal is equipped with is not limited to switch 31.Monitoring terminal can also be equipped with sensor.
In the situation that receiving supervision input, each monitoring terminal is sent to transmission unit 1 by the control request corresponding with this supervision input.Transmission unit 1, in the situation that receiving control request, utilizes address that control command is sent to the control terminal corresponding with this monitoring terminal.This control terminal, in the situation that receiving control command, is controlled controlled device 32 according to this control command.For example,, by making to be switched on or switched off control connection to the load (electric equipment) of controlled device 32 as the repeater of controlled device 32.Control command has reflected the supervision input of inputting from switch 31, and therefore the operation for switch 31 is finally reflected in the control for controlled device 32.
Transmission unit 1 is stored in the control table that utilizes address that switch 31 and controlled device 32 are corresponded to each other in memory cell 12 (referring to Figure 1B).Here, for example, in the situation that terminal installation 3 has the switch 31 of multichannel, be dispensed to the peculiar terminal address of terminal installation 3 and the switch 31 on all roads of terminal installation 3 is corresponding.Therefore, only utilize this peculiar terminal address, cannot specify unique switch 31 of real work.Therefore, in operating terminal, thereby to switch 31Ge road, assign load numbering to specify unique switch 31 of real work.Then, the address that use is added with load numbering after the peculiar terminal address of terminal installation 3 is as the peculiar address (identifier) that is dispensed to switch 31.Equally, in control terminal, to each repeat circuit distribution load numbering of controlled device 32.Then, the address that use is added with load numbering after the peculiar terminal address of terminal installation 3 is as the peculiar address (identifier) that is dispensed to controlled device 32.
As shown in Figure 1B, transmission unit 1 comprises transmission processing unit 11, memory cell 12, uses communication module 9, the laminating module as described below 8 of the communication of signal transmission and memory cell 13 is set.Communication module 9 comprises that transmission sends receiving element 92 and is connected to transmission data analysis unit 93 and the transmission data generating unit 94 that transmission sends receiving element 92.
Transmission sends the waveform that receiving element 92 generates transmission data, then on communication line 2, sends the signal or the signal transmission from communication line 2 that generate and receives return signal.Transmission data analysis unit 93 is analyzed the content that transmission sends the received return signal of receiving element 92.Transmission data generating unit 94 generates the data of utilizing signal transmission to send, then these data is sent to receiving element 92 via transmission and is sent to terminal installation 3.Transmission processing unit 11, with reference to being stored in the control table in memory cell 12, then utilizes signal transmission to carry out the supervision of switch 31 and the control of controlled device 32.Here, transmission unit 1 also has the operating state of monitoring terminal device 3 termly and these operating states is stored in to the function in memory cell 12.
The operation of fundamental system then, is below described.
As shown in Figure 2, the transmission unit 1 as machine tool is sent to communication line 2 by the signal transmission of time division way.This signal transmission comprises the voltage waveform with the form that is divided into a plurality of bands on time-axis direction.That is to say, signal transmission is the time division multiplexed signals with bipolar (± 24V), wherein this time division multiplexed signals comprise preparation band of discontinuance 21, preparation be with 22, send be with 23, reply be with 24, band of discontinuance 25, short-circuit detecting band 26 and stop and be with 27.Preparation band of discontinuance 21 is to interrupt the set time period in order to detect secondary.Preparation is according to band of discontinuance 25 and set time period of short-circuit detecting band 26 with 22.Transmission is in order to send data to the set time period of terminal installation 3 with 23.Reply is the set time slots of return signal that return from terminal installation 3 in order to receive with 24.Band of discontinuance 25 is in order to detect the set time period of interrupt signal as described below.Short-circuit detecting band 26 is in order to detect the set time period of short circuit.Stopping with 27 is for processing the unpunctual set time period of situation.
In each terminal installation 3, in the situation that the transmission of the address of storing and the signal transmission having received via communication line 2 is consistent with address date included in 23 in its oneself memory (not shown), terminal installation 3 extracts for controlling the control command of controlled device 32 from this signal transmission.In addition, terminal installation 3 synchronously returns to this control result as the signal (signal that communication line 2 short circuits is sent by the Low ESR via suitable) of current-mode with the reply of signal transmission with 24.Here, by being carried out to rectification stabilisation, the signal transmission coming via communication line 2 transmission to supply with electric power to the internal circuit of each terminal installation 3.
Transmission unit 1 is conventionally in the situation that the address date comprising in periodically-varied signal transmission carries out poll continuously with each terminal installation 3 of sequential access.When continuous poll, in the situation that the address of terminal installation 3 is consistent with address date included in signal transmission, if this signal transmission has comprised control command, the terminal installation 3 with appropriate address extracts these control commands to carry out work.Then, the terminal installation 3 that has an appropriate address is back to transmission unit 1 using its oneself operating state as controlling result.
In the situation that receive the interrupt signal generating in response to the supervision input of the switch 31 being equipped with from any monitoring terminal (terminal installation 3), transmission unit 1 search has generated the terminal installation 3 of this interrupt signal, then accesses this terminal installation 3 and interrupts poll.
That is to say, transmission unit 1 transmits according to the signal transmission of normal mode conventionally as mode data.Then, in the situation that the interrupt signal generating in monitoring terminal (terminal installation 3) synchronously being detected with the band of discontinuance 25 of signal transmission, transmission unit 1 transmission according to the signal transmission that interrupts poll pattern as mode data.
Generated interrupt signal terminal installation 3 in the situation that the high-order position of its oneself address with consistent according to the high-order position of address date included in interrupting the signal transmission of poll pattern, with the reply of this signal transmission with 24 low-order bits that synchronously return to its own address as replying data.Therefore, transmission unit 1 can obtain the address of the terminal installation 3 that has generated interrupt signal.
In the situation that obtain the address of the terminal installation 3 that has generated interrupt signal, transmission unit 1 transmission is for requiring terminal installation 3 to return to the signal transmission of the request of control.Then, terminal installation 3 by with from the supervision of switch 31, input corresponding control request and be back to transmission unit 1.In the situation that receiving this control request, transmission unit 1 is sent to terminal installation 3 by the indication that monitors input for removing.Then, terminal installation 3 is removed this and is monitored input.
The transmission unit 1 that receives the request of control generates for utilizing the corresponding relation of address to be sent to the control command of the terminal installation (control terminal) 3 corresponding with the terminal installation (monitoring terminal) 3 of the transmission source of asking as this control.Then, transmission unit 1 is sent to communication line 2 by the signal transmission that comprises this control command, so that terminal installation (control terminal) 3 controlled devices that are equipped with 32 are controlled.
As mentioned above, in fundamental system, terminal installation (monitoring terminal, control terminal) 3 communicates via transmission unit 1 each other according to poll/selection protocol (the first agreement).
In the control table of transmission unit 1, make switch 31 corresponding in man-to-man mode with controlled device 32, yet can also make switch corresponding in the mode of one-to-many with controlled device.For example, in the situation that use controlled device 32 to be switched on or switched off towards the power supply of the lighting apparatus as load, the individuality that transmission unit 1 can utilize the switch 31 on 1 tunnel to control the lighting apparatus on 1 tunnel is controlled or is utilized the integral body of lighting apparatus of the whole control multichannel of switch 31 on 1 tunnel to control.Whole control comprises that group is controlled and pattern is controlled.It is following control that group is controlled: make as a plurality of repeaters of control object and the switch 31 on 1 tunnel correspondingly, and be switched on or switched off a plurality of repeaters by whole to the operation of switch 31.It is following control that pattern is controlled: make the switch 31 on the state of a control (ON (connections) or OFF (disconnection)) corresponding with a plurality of repeaters as control object and each repeater and 1 tunnel corresponding, and by the operation of switch 31 is switched on or switched off to a plurality of repeaters.
In order to realize, group is controlled and pattern is controlled, and transmission unit 1 also comprises memory cell 13 is set, and wherein this arranges the configuration information of using when memory cell 13 storages are carried out whole control to a plurality of controlled devices 32.This configuration information at least comprises and is dispensed to the combination of the peculiar address of the controlled device 32 of control object (hereinafter referred to as " individual addresses ") as a whole.In the present embodiment, this configuration information comprises the combination information corresponding with group address or pattern address that makes individual addresses.In control table, the address of switch 31 of carrying out work when group address and group are controlled is corresponding.In control table, the address of switch 31 of carrying out work when pattern address is controlled with pattern is corresponding.
Therefore,, when the switch corresponding with group address or pattern address 21 carries out work, transmission unit 1, by contrast to launch the address as the controlled device 32 of control object with configuration information, then sends control command to these controlled devices 32.
To that is to say, in order organizing, to control or pattern control, need to set in advance and represent that each controlled device 32 belongs to the configuration information of which group (or which pattern).Setting device 4 is for the device of this set information is set.In order to carry out the transmission of configuration information, process, this setting device makes transmission unit 1 carry out configuration information towards writing of memory cell 13 is set by configuration information is sent to (transmission) to transmission unit 1.
As shown in Figure 3, identical with the situation of transmission unit 1, setting device 4 comprises communication module 9.Setting device 4 also comprises: set handling unit 41, for carrying out the setting of configuration information; Input unit 42; Display unit 43; And memory cell 44.Therefore, user can input configuration informations via input unit 42 when display unit 43 places check that inner core is set.Then, inputted configuration information is stored in memory cell 44 via set handling unit 41 temporarily.The registration (towards writing of memory cell 13 is set) that setting device 4 carries out configuration information by the configuration information in memory cell 44 being sent to transmission unit 1.
Server unit 5 is configured to utilize the Web browser function of client terminal 7 to carry out the information of monitoring and controlling terminal installation 3 (operating state of switch 31 and controlled device 32 etc.) via network 6.Be not particularly limited client terminal 7, as long as client terminal 7 comprises the user interface such as Web browser function, display unit and operating unit etc.In this case, use personal computer as client terminal 7.
As shown in Figure 4, identical with the situation of transmission unit 1, server unit 5 comprises communication module 9.Server unit 5 also comprises: memory cell 51, for storing configuration information; And Web picture Component units 52, it is connected to set handling unit 41 and web content is provided to client terminal 7.Server unit 5 is also as setting device.Therefore, even if user also can use client terminal 7 to carry out the setting of configuration information from remote place.Then, inputted configuration information is stored in the memory cell 51 of server unit 5.Here, the memory cell 51 of server unit 5 is also stored for terminal installation 3 being carried out to list-directed timetable data of time according to timetable.
Here, in traditional communication system, conventionally, utilize signal transmission that configuration information as above is sent to transmission unit 1 from setting device 4 or server unit 5.As concrete grammar, there is the first method and the second method, wherein in this first method, in the situation that the control of the supervision of switch 31 and controlled device 32 all interrupts transmitting configuration information, and in this second method, in the supervision of switch 31 and the control of controlled device 32, all in continuation, transmit configuration information.
In the first method, setting device 4 or server unit 5, at the supervision of switch 31 and the control intercourse of controlled device 32, exclusively utilize signal transmission to transmit configuration information.In the second method, setting device 4 or server unit 5 generate interrupt signal, then receive interruption poll from transmission unit 1 after, transmit configuration information.
Yet in the first method, between the transmission period of configuration information, transmission unit 1 can neither carry out the supervision of switch 31 and also not carry out the control of controlled device 32, the problem that therefore exists the work essence of fundamental system to stop.Especially, arranging of group address or pattern address, greatly (for example count, pattern address arrange number be 72 and group address number is set is 128) situation under, time that need to be relatively long (for example, approximately 30 minutes) is carried out the transmission of configuration information.As a result, the work dwell time of fundamental system is elongated.
In addition, in the second method, because setting device 4 or server unit 5 transmit configuration information by interruption, in the supervision of switch 31 of therefore carrying out at transmission unit 1 and the control of controlled device 32, postpone, thereby postpone in the work of fundamental system.In addition, about the transmission of configuration information, the second method is compared time that need to be longer with the first method.As a result, required time of the registration of configuration information is elongated.
In order to address these problems, according to the communication system of the present embodiment, at as above group, control or when pattern controls the registration of configuration information used or synchronous etc. transmission, not to utilize signal transmission but utilize superposed signal.
Particularly, according in the communication system of the present embodiment, transmission unit 1, the setting device 4 with the function that this configuration information is set and the server unit 5 of registration configuration information are respectively arranged with laminating module 8 (referring to Figure 1B, Fig. 3 and Fig. 4).Laminating module 8 is in shared fundamental system and communication line 2, with being superimposed upon the communication interface that the superposed signal on signal transmission communicates each other.Laminating module 8 utilizes superposed signal that configuration information is sent to transmission unit 1 from setting device 4 or server unit 5.The communication that utilizes superposed signal to carry out detailed description below.
Each laminating module 8 is according to the agreement (second protocol) different from above-mentioned the first agreement, is directly sent to other laminating module 8 will transmit data (configuration information) by peer-to-peer network (P2P) without via transmission unit 1 in the situation that.
As shown in Figure 1B, laminating module 8 comprises: superpositing unit 81, and it is connected to communication line 2; Stack sends receiving element 82, and it is connected to superpositing unit 81; Superposition of data analytic unit 83; And superposition of data generation unit 84.Superposition of data analytic unit 83 and superposition of data generation unit 84 are connected to stack and send receiving element 82.
Utilize this structure, each laminating module 8 is superimposed upon according to second protocol the bag that comprises the data that will be sent to other laminating module 8 on signal transmission, then this signal is sent to communication line 2 or receives the bag of the second protocol send from other laminating module 8.That is to say carrying out via transmission unit 1 as mentioned above according to the communication of the first agreement between terminal installation 3, and on the other hand, directly not carrying out according to the communication of second protocol between laminating module 8 in the situation that relying on transmission unit 1.As a result, and compare according to the communication speed of the communication of the first agreement, according to the communication speed of the communication of second protocol, can further improve.Then, according to the communication of second protocol, can be used for that transmission such as group is controlled or pattern is controlled configuration information used etc. and control request or control command and compare the information that data volume is large.
In addition, each laminating module 8 comprises judging unit 85, and the signal transmission wherein transmitting between the transmission unit 1 of 85 pairs of fundamental systems of this judging unit and terminal installation 3 monitors.Judging unit 85 is analyzed transmission status (hereinafter referred to as " state ") based on this signal transmission.Laminating module 8 judges whether the state that judging unit 85 is analyzed is the state that is applicable to the stack of superposed signal.Then, at laminating module 8, be judged as the moment that this state is applicable to transmission, superpositing unit 81 is superimposed upon superposed signal on signal transmission.
Here, the signal transmission adopting has signal format as shown in Figure 2.In preparation band of discontinuance 21, preparation, be with 22 or stop and be with in 27, even if carry out the stack of superposed signal, also do not affect according to the communication of the first agreement.In addition, signal transmission can affect superposed signal hardly.Therefore, preparation band of discontinuance 21, preparation are with 22 with to stop with 27 are the bands (hereinafter referred to as " stackable band ") that make it possible to carry out the stack of superposed signal.In addition, in the present embodiment, although be elaborated below, except these three bands, laminating module 8 land productivity of also having ready conditions is with 24 as stackable band with replying.
In other band (transmission is with 23, band of discontinuance 25 and short-circuit detecting band 26), steady signal transmission is relatively short at high level or low level time, therefore, the in the situation that of stack in being with these other, superposed signal is easily to exerting an influence according to the communication of the first agreement.In addition, as mentioned above, in the situation that other carries out the stack of superposed signal in being with, the signal of sending and receiving between transmission unit 1 and terminal installation 3 (interrupt signal or reply data) also easily exerts an influence to superposed signal.Therefore, other band as above is the band that can not carry out the stack of superposed signal (hereinafter referred to as " can not stacked tape ").
In addition, due to the impact of higher harmonics noise or be attended by the impact etc. of transient response of the voltage reversal of signal, thereby rise time of signal transmission and be not suitable for carrying out the stack of superposed signal fall time.Therefore,, even be with 22 or stop and be with 27 in preparation band of discontinuance 21, preparation, being also defined as can not stacked tape the switching of band (rise and decline) predetermined amount of time (for example, 300 μ s) afterwards.
Here, the analysis result that judging unit 85 is configured to the state based on signal transmission judges that band is stackable band or can not stacked tape, and then superpositing unit 81 is only configured to be judged as and the in the situation that band being stackable band, just to send superposed signal at judging unit.As mentioned above, thereby laminating module 8 only just carries out the stack of superposed signal in the stackable band of signal transmission, synchronize with signal transmission, therefore can prevent shared communication line 2 according to the communication of the first agreement with according to communicating by letter of second protocol, influence each other.
Here, large and cannot only send in single stackable band in the situation that owing to sending the data volume of data at laminating module 8, laminating module 8 interrupt communication when this stackable end of tape, and send remaining data in next stackable band.That is to say, in the situation that receive the superposed signal sending with partitioning scheme, stack send receiving element 82 by these partition datas in conjunction with to obtain initial data, and in the situation that sending superposed signal, this unit 82 by Data Segmentation become to have can be superimposed upon stackable with on big or small data acquisition system.
Identical with the situation of terminal installation 3, use by the signal transmission coming from transmission unit 1 transmission via communication line 2 being carried out to rectification stabilisation and supply with the system of electric power (central power supply system) and supply with electric power to each unit in laminating module 8.Yet electric power system is not limited to this structure.Can be with supplying with the system of electric power (local power system) and supply with electric power to each unit in laminating module 8 by commercial power being carried out to rectification stabilisation.
Here, conventionally, in signal transmission, only will prepare band of discontinuance 21, prepare with 22 and stop with 27 stacks for superposed signal as stackable band.On the other hand, except preparation band of discontinuance 21, preparation are with 22 and stop and be with 27 these three bands, the laminating module 8 of the present embodiment also conditionally using reply with 24 stacks for superposed signal as stackable band.
That is to say, judging unit 85 is for each frame of signal transmission, during the predetermined detection time period that judgement is lighted with 24 time started in reply, have or not return signal, the reply that then laminating module 8 is used judging units 85 to be judged as not exist return signal with 24 as the stackable band that can carry out the stack of superposed signal.On the other hand, laminating module 8 is used judging units 85 to be judged as to exist the reply of return signal to be with 24 as can not stacked tape.
More specifically, as shown in Figure 5, reply and be with 24 to comprise these five pieces of " B1 "～" B5 ".In the situation that terminal installation 3 places generate return signal, for example, within the scheduled time (, 900 μ s) of lighting with 24 time started from reply, pulsing in initial piece B1.Here, judging unit 85 will be defined as section T1 detection time from replying the predetermined amount of time of lighting with 24 time started.Then, in the situation that do not have pulsing in section T1 detection time, judging unit 85 is judged as and does not have return signal, and reply is distributed as stackable band with the time period T2 from second piece B2 in 24.In the example of Fig. 5, the length of replying with 24 is 6400 μ s, and from reply with 24 time started, light detection time section T1 length be 1900 μ s.In the situation that do not have pulsing in section T1 this detection time, the time period T2 that is 4500 μ s using remaining length distributes as stackable band.On the other hand, in this detection time section T1, pulsing in the situation that, judging unit 85 is judged as and in reply is with 24, has return signal, and this is replied to band and distribute as can not stacked tape.
In the situation that as shown in following table 1, even can use reply with in 24 except the part detection time section T1 is as stackable band, with reply is compared as situation that can not stacked tape with 24 whole region allocation, for the data volume of the stackable band of each frame of signal transmission, significantly increase.Table 1 for reply with 24 be not used in superposed signal stack situation and reply a part with 24 (except the part detection time section) for each situation of the situation of the stack of superposed signal, be illustrated in data volume, its total and communication speed that each can transmit in being with.Here, the data that can transmit 40 by supposing in 1ms are calculated these values.
table 1
| ? | Do not use and reply band | Use and reply band |
| Band stops | 40 | 40 |
| Preparation band of discontinuance | 40 | 40 |
| Preparation band | 40 | 40 |
| Reply band | 0 | 180 |
| Add up to | 120 | 300 |
| Communication speed | 6.3kbps | 15.7kbps |
As mentioned above, by even use replying, with a part of 24, carry out the stack of superposed signal, the data volume of the superposed signal that can superpose for each frame of signal transmission significantly increases, and has improved communication speed.In the example of table 1, in the situation that reply is 6.3kbps with the 24 stack communication speeds that are not used in superposed signal.On the other hand, in the situation that reply is with 24 stacks for superposed signal, communication speed rises to 15.7kbps.
Here, as an example, utilize the configuration information that superposed signal transmits to there is the signal structure as shown in Fig. 6 A or 6B.That is to say, for example as shown in Figure 6A, with pattern control relevant configuration information by type 61, address 62, decay position 63, module information 64, verification and 65 and clearing end 66 form.In the example of Fig. 6 A, type 61 has the data of 16, and address 62 has the data of 12, and decay position 63 has the data of 4, and module information 64 has the data of 4288, and verification and 65 has the data of 8, and clearing end 66 has the data of 8.Therefore, configuration information has the data of 4336 for each pattern.
In module information 64, for each individual addresses, Control the content, timer and dimming level (load is the situation of lighting apparatus) etc. are set.Control the content is selected from " ON (connection) ", " OFF (disconnection) " and " eliminating " alternatively.In the situation that load is lighting apparatus, timer is selected from " nothing ", " lighting a lamp 30 seconds ", " lighting a lamp 1 minute ", " lighting a lamp 5 minutes ", " lighting a lamp 60 minutes ", " lighting a lamp 120 minutes ", " postponing light-off in 30 seconds ", " postponing light-off in 1 minute " and " postponing light-off in 5 minutes " alternatively temporarily temporarily temporarily temporarily temporarily.Dimming level is alternatively from representing step by step from extinguishing state to selected the value of " 0 "～" 128 " of the lightness of full illuminating state.
For example as shown in Figure 6B, with group control relevant configuration information by type 61, address 62, module information 64, verification and 65 and clearing end 66 form.In the example of Fig. 6 B, type 61 has the data of 16, and address 62 has the data of 12, and module information 64 has the data of 2048, and verification and 65 has the data of 8, and clearing end 66 has the data of 8.Therefore, configuration information has the data of 2284 for each group.
Here, the data volume of the configuration information for each pattern or each group based on above-mentioned and the communication speed shown in above-mentioned table 1, obtain and transmit the required time of this configuration information as shown in the following Table 2.Table 2 for reply with 24 be not used in superposed signal stack situation and reply each situation for the situation of the stack of superposed signal with a part of 24, the required time of each configuration information of transmitting 1 pattern, 72 patterns, 1 group and 128 groups is shown.
table 2
| ? | Do not use and reply band | Use and reply band |
| 1 pattern | 0.69s | 0.28s |
| 72 patterns | 49.68s | 20.16s |
| 1 group | 0.37s | 0.15s |
| 128 groups | 47.36s | 19.20s |
According to the communication system of the present embodiment as above, owing to transmitting configuration information by superposed signal, even therefore this system in the situation that continue the supervision of switch 31 and the control of controlled device 32 further to transmit configuration information, also can prevent from postponing in the work of fundamental system.In addition, because the communication system of the present embodiment land productivity of also having ready conditions carries out the stack of superposed signal with the reply in signal transmission with 24, therefore with 24 situation, compare with not utilizing to reply, for the data volume of the stackable band of each frame of signal transmission, significantly increase.Therefore, can shorten configuration information is sent to the required time of transmission unit 1 from setting device 4 or server unit 5, and can shorten the required time of registration of configuration information.Especially, the magnitude setting of group address or pattern address large (for example, pattern address arrange number be 72 and group address number is set is 128) situation under, the required time of transmission of configuration information significantly shortens.
In the present embodiment, due to setting device 4 and server unit 5, not only comprise separately laminating module 8 but also comprise communication module 9, therefore can also utilize signal transmission that configuration information is sent to transmission unit 1.For example, by the operation to setting device 4 or server unit 5, can switch arbitrarily the signal that signal transmission and superposed signal are used as transmission configuration information.
In the present embodiment, laminating module 8 is used from replying the predetermined amount of time lighted with 24 time started as section detection time that judges judging unit 85 that having or not of return signal is used.Yet, can also use the reply that comprises this of section detection time with 24 whole region as stackable band.
That is to say, in this case, laminating module 8 comprises interruption generation unit (not shown), and wherein this interruption generation unit generates on one's own initiative interrupt signal in band of discontinuance 25 (referring to Fig. 2).This interruption generation unit provides interruption, therefore can use next reply with 24 whole region as stackable band.Interrupting generation unit generate interrupt signal in the situation that, laminating module 8 can in the situation that next reply with in 24 without making judging unit 85 judge having or not of return signals, in next reply, carry out the stack of superposed signal in 24 whole region.
In the situation that use to reply with 24 whole region as stackable band, in the example of Fig. 5, interpolation from reply the length of lighting with 24 time started be 1900 μ s detection time section T1 as stackable band, so the stack of superposed signal is carried out in the reply that laminating module 8 can add up to 6400 μ s in length in 24 whole region.Under the condition identical with table 1, laminating module 8 is used replys with 24 whole region as stackable band, therefore reply with 24 in laminating module 8 can transmit greatly the data of 76.As a result, can utilize superposed signal to transmit for the large data of 4k position per second.That is to say, communication speed has improved 4kbps.
As shown in Figure 7, transmission unit 1 can also comprise buffer storage 14 and collision detection unit 15, and can be configured to receive at the same time in the control request of controlled device 32 and the situation of configuration information, this control request is stored in buffer storage 14 temporarily.Collision detection unit 15 detects from terminal installation 3 and utilizes conflicting between control request that signal transmission transmission comes and the configuration information of utilizing superposed signal to send from setting device 4 or server unit 5.That is to say, in the situation that communication module 9 receives the moment of the request controlled is overlapping with the moment that laminating module 8 receives configuration information, collision detection unit 15 is judged as the request of control and configuration information is conflicted each other.
In this structure, the in the situation that of conflict being detected in collision detection unit 15, transmission unit 1 is stored in now received control request in buffer storage 14 temporarily.In this case, in the situation that configuration information is towards having write of memory cell 13 is set, the control request in transmission processing unit 11 playback buffer memories 14, is then sent to terminal installation 3 based on this control request by control command.
In the structure that comprises buffer storage 14 and collision detection unit 15 as above, in the situation that conflict each other with respect to control request and the configuration information of transmission unit 1, utilize transmission unit 1 that control request is stored in buffer storage 14 temporarily, and preferentially carry out towards the registration that the configuration information of memory cell 13 is set.Therefore, can complete as early as possible the registration process of the configuration information of utilizing setting device 4 or server unit 5.In addition, even in the situation that with the change of configuration information in integral body controlled to switch used 31 operate, transmission unit 1 also can carry out integral body control by the new configuration information after changing.
Here, the part band as stackable band of being assigned with in signal transmission can be only for the synchronous synchronization dedicated band of the configuration information between a plurality of laminating modules 8.That is to say, in the communication system of the present embodiment, not only group is controlled or pattern control configuration information used as primary data store in transmission unit 1, but also be stored in the arranging in memory cell 13 of setting device 4 or server unit 5.Therefore,, in the situation that the duration of work of communication system exchanges or adds setting device 4 or server unit 5, between transmission unit 1, setting device 4 and server unit 5, may there is inconsistent (not the mating) of configuration information.In this case, need to make the configuration information in transmission unit 1 as primary data store synchronize with the configuration information being stored in setting device 4 and server unit 5, thereby guarantee the coupling of the configuration information of communication system integral body.
Therefore, transmission unit 1 is set to synchronization dedicated band regularly by the part band of signal transmission.Then, transmission unit 1 is used synchronization dedicated band, utilizes superposed signal using configuration information as master data, to be sent to setting device 4 and server unit 5, thereby makes configuration information synchronous.In the situation that receiving configuration information from transmission unit 1, setting device 4 and server unit 5 compare received configuration information and the configuration information arranging in memory cell 13 of himself separately, then between these configuration informations, exist in inconsistent situation, received configuration information is write to self memory cell 13 is set.Therefore, can carry out for each frame of signal transmission the synchronous of configuration information, and guarantee all the time the coupling of the configuration information of communication information integral body.
Although exemplify in the present embodiment the structure that each laminating module 8 is built in transmission unit 1, setting device 4 and server unit 5, communication system is not limited to this structure.For example, laminating module 8 can be arranged with transmission unit 1, setting device 4 and server unit for 5 minutes, and can be connected directly to transmission unit 1, setting device 4 and server unit 5.
The difference of the communication system of the communication system of the present embodiment and embodiment 1 is: this system is configured to tackle even many setting devices 4 or server unit 5 carries out the situation of the setting of configuration information simultaneously.Below, the in the situation that of not special difference setting device 4 and server unit 5, the two integral body is called to " setting unit ".The present embodiment will comprise that with each setting unit communication module 9 and the prerequisite that can communicate with signal transmission describe.
For example, carry out following supposition: in the situation that specific setting unit transmits configuration information, user uses other setting unit to carry out the setting of configuration information.In this case, because superposed signal is by exclusively using for transmitting the specific setting unit of configuration information, therefore cannot utilize superposed signal to transmit the set configuration information of user.Therefore, in the present embodiment, in the situation that two setting units are carried out the setting of configuration information simultaneously, a setting unit utilizes signal transmission to transmit configuration information, and another setting unit utilizes superposed signal to transmit configuration information.Particularly, each setting unit has for by communicating to distribute signal transmission and superposed signal so that transmit the method for configuration information and the unduplicated arbitration function of method that other setting unit is used with other setting unit.
In the situation that utilize signal transmission and superposed signal to receive different configuration informations from two setting units as mentioned above, transmission unit 1 has following structure, makes these different configuration informations not to be write simultaneously memory cell 13 is set.That is to say, transmission unit 1 alternately switches communication module 9 and laminating module 8 as the destination of reading configuration information, thereby by utilizing the received configuration information of signal transmission and utilizing the received configuration information of superposed signal alternately to write, memory cell 13 is set.Particularly, transmission unit 1, for each registration of the configuration information of each pattern or each group (each group address or each pattern address), is used semaphore (semaphore) to carry out exclusive control, and alternately switches communication module 9 and laminating module 8.
According to said structure, in the situation that two setting units are carried out the setting of configuration information simultaneously, a setting unit is switched for transmitting the method for configuration information in response to the trend of another setting unit, therefore configuration information can be sent to transmission unit 1 effectively.
In addition,, in the situation that more than three setting units is carried out the setting of configuration information simultaneously, a setting unit utilizes signal transmission to transmit configuration information, and remaining setting unit utilizes superposed signal to transmit configuration information.In this case, because many setting units are utilized superposed signal and carried out the setting of configuration information, therefore preferably different stackable bands is dispensed to many setting units in turn.
For example, in the situation that three setting units are carried out the setting of configuration information simultaneously, a setting unit utilizes signal transmission to transmit configuration information, and another two setting units utilize superposed signal to transmit configuration information.Here, different stackable bands is respectively allocated to another two setting units of utilizing superposed signal to transmit, and stackable the bringing that each setting unit utilization distributes is sent to transmission unit 1 by configuration information.Now, two setting units utilizing superposed signal to transmit configuration information are configured to switch termly according to the data volume of configuration information the band of the stack of carrying out superposed signal.
Particularly, as shown in Figure 8, the address (group address or pattern address) that first two setting units utilizing superposed signal to transmit configuration information will arrange to transmission unit 1 notice.The data volume (amount of communication data) of calculating and setting information is carried out in the address of transmission unit 1 based on received, and the stackable band that the transmission of configuration information is used is dispensed to each setting unit, and notifies these stackable bands to each setting unit.Here, be with 24 as stackable band in the situation that cannot use to reply, transmission unit 1 is divided into preparation band of discontinuance 21 and preparation by other stackable band and is with 22 and stop and be with 27 these two groups, then by preparation band of discontinuance 21 and preparation with the 22 larger setting units of data volume that are dispensed to configuration information, and by the less setting unit of data volume of stopping and being dispensed to configuration information with 27.On the other hand, be with 24 as stackable band in the situation that can use to reply, transmission unit 1, for two setting units utilizing superposed signal transmission configuration information, checks the remaining data amount of configuration information termly, then according to the flow chart of Fig. 9, distributes stackable band.
That is to say, as shown in Figure 9, transmission unit 1 checks remaining data amount (S0) termly, and calculates the difference (poor) between the remaining data amount of these two setting units.In the situation that the difference between remaining data amount is less than 40 (being "No" in S1), transmission unit 1 by reply with 24 more setting units of remaining data amount that are dispensed in these two setting units, and by preparation band of discontinuance 21 and preparation with 22 or the less setting unit (S2) of remaining data amount of stopping and being dispensed in these two setting units with 27.Then, in the situation that the difference between remaining data amount is more than 40 (being "Yes" in S1) and be less than 140 (being "No" in S3), transmission unit 1 will stop with 27 or reply with 24 larger setting units of remaining data amount that are dispensed in these two setting units, and will prepare band of discontinuance 21 and preparation with the 22 less setting units (S4) of remaining data amount that are dispensed in these two setting units.Then, in the situation that the difference between remaining data amount is more than 140 (being "Yes" in S3) and be less than 220 (being "No" in S5), transmission unit 1 will prepare band of discontinuance 21 and preparation with 22 or reply with 24 larger setting units of remaining data amount that are dispensed in these two setting units, and by the less setting unit (S6) of remaining data amount of stopping and being dispensed in these two setting units with 27.Then, in the situation that the difference between remaining data amount is more than 220 (being "Yes" in S5), transmission unit 1 by preparation band of discontinuance 21 and preparation with 22, reply with 24 and the larger setting unit of remaining data amount of stopping and being dispensed in these two setting units with 27, and to the less setting unit of remaining data amount in these two setting units, do not distribute stackable band (S7).
According to structure as above, even in the situation that more than three setting units is carried out the setting of configuration information simultaneously, each setting unit also can and be about to configuration information and be sent to transmission unit 1.Therefore, even in the situation that many setting units are carried out the setting of configuration information simultaneously, in transmission unit 1, the registration of configuration information also completes in same time section, therefore can shorten the unmatched time period of configuration information in communication system integral body.
Other 26S Proteasome Structure and Function is identical with the 26S Proteasome Structure and Function of embodiment 1.
Although the present invention has been described with reference to certain preferred embodiment, those skilled in the art can be not deviating from true spirit of the present invention and scope, make various changes and modifications be claims in the situation that.
