Superposition terminal 22 possesses as shown in Figure 1: superposition Department of Communication Force 23, consists of the communication carrying out using superposed signal; Transmission acceptance division 24, consists of the data receiving transmission unit 1 and sent by signal transmission in transmit band 103; Interface portion 25; And (end side) control part 26.Further, superpose terminal 22 and possess judging part 27 described later, reservation portion 28 and handling part 29.Interface portion 25 connects sensor device described later, ligthing paraphernalia 3.Control part 26 is configured to control the action of superposition Department of Communication Force 23, transmission acceptance division 24, interface portion 25, judging part 27, reservation portion 28, handling part 29.In the present embodiment, superposition terminal 22 take microcomputer as main structure, is realized the function in each portion by the program stored in execute store (not shown).
At this, superposed signal is the sufficiently high signal of frequency compared with signal transmission, and the data volume that (signal transmission) every frame can transmit is abundant.Therefore, compared with the communication based on the first agreement, the communication based on second protocol can make communication speed high speed, is suitable for the transmission of the many information of the such data volume of such as analog quantity.
Fig. 1 represents an example of the control for carrying out multiple ligthing paraphernalia 3 with a sensor device 9.In FIG, in order to carry out the controls such as unlatching control, closing control and brightness adjustment control to multiple ligthing paraphernalia 3, such as sensor device 9 comprises the transducer such as existence and non-existent infrared ray sensor for detecting people and the illuminance transducer for the illumination of measuring surrounding, does not limit this.Second control terminal 222 is not only used in simple unlatching control and the closing control of multiple ligthing paraphernalia 3, is also used in such as brightness adjustment control, communication that toning controls the many control datas of such data volume.That is, the second control terminal 222 with can carry out brightness adjustment control, the ligthing paraphernalia 3 controlled of mixing colours is connected, be configured to according to the control data using superposed signal to send to carry out the control of ligthing paraphernalia 3.In the example in figure 2, the sensor devices 9 such as imageing sensor (not shown), power measurement unit 91 are connected with the second monitoring terminal 221, and the second monitoring terminal 221 is used in the communication of the many supervision data of data volume.
The superposition terminal 22 of present embodiment is configured to obtain by transmission acceptance division 24 data sent by signal transmission from transmission unit 1.But transmission acceptance division 24, without the need to understanding from whole signal transmissions of transmission unit 1, described laterly guarantees data as long as at least can understand whether to include in the transmit band 103 of signal transmission.
At this, what generate supervision data is sensor device 9, and the second monitoring terminal 221 is as the supervision inputted from sensor device 9 data being converted to the superposed signal of second protocol and this superposed signal being sent to the adapter on order wire 10 and playing function.Similarly, the second control terminal 222 is converted to the control signal corresponding with the specification of ligthing paraphernalia 3 as by the control data corresponding to the superposed signal received from order wire 10 (supervision data) and this control signal is outputted to the adapter of ligthing paraphernalia 3 and plays function.That is, the second control terminal 222 has the memory of storage list, in the table, monitor that multiple key element of data group is corresponding with multiple key elements of control data group, at this, monitor that data group comprises a group and monitors data, control data group comprises a group control data.In the example in fig 1, such as when sensor device 9 comprises the transducer such as existence and non-existent infrared ray sensor for detecting people and the illuminance transducer for the illumination of measuring surrounding, multiple key elements of the supervision data group of sensor device 9 are corresponding with multiple key elements of the control data group of multiple ligthing paraphernalia 3 respectively, do not limit this.In addition, as an example of the specification of the ligthing paraphernalia 3 be connected with the second control terminal 222, DALI (Digital Addressable Lighting Interface: digital addressable lighting interface) etc. is had.
In addition, superpose terminal 22 and there is following functions: the signal transmission used in fundamental system is monitored, the transmission status (hereinafter referred to as " state (state) ") of signal transmission is analyzed.At this, superposition terminal 22 is configured to be monitored by transmission acceptance division 24 pairs of signal transmissions.In addition, superposition terminal 22 is configured to: judge whether the next foldback band 104 arrived is the stackable band being suitable for superposing superposed signal by judging part 27 according to the analysis result of state, be judged as the timing of this foldback band 104 of stackable band, by superposition Department of Communication Force 23, superposed signal be superimposed upon on signal transmission.
In the present embodiment, superpose terminal 22 the foldback band 104 (with reference to Fig. 3) of signal transmission is brought for superposing superposed signal as stackable.That is, if which communication terminal 21 does not use foldback band 104, even if then superpose superposed signal in foldback band 104, also can not have an impact to the communication of the first agreement, but also superposed signal can be prevented to be subject to the impact of signal transmission.Further, foldback band 104 with preparation band of discontinuance 101, prepare band 102, suspends band 107 compared with, steady signal transmission high level or the low-level time long, signal transmission in a frame shared by ratio greatly, be therefore suitable for superposition superposed signal.
About other region (transmit band 103, band of discontinuance 105 and short-circuit detecting band 106), steady signal transmission high level or the low-level time relatively short, if superposition superposed signal; the easy communication to the first agreement have an impact.In addition, if in above-mentioned other region superposition superposed signal, then the superposed signal impact of signal (interrupt signal, send data) that is also easily subject to giving and accepting between transmission unit 1 and communication terminal 21.Therefore, in the present embodiment, the region beyond foldback band 104 is set to the region (hereinafter referred to as " can not stacked tape ") of the superposition not being used in superposed signal.
In addition, illustrate concrete numerical value then as follows: if establish the Shi Kuanwei of foldback band 104 to be about 6.5ms and superpose terminal 22 can superpose 5 bytes (byte) in 700 μ s data by superposed signal, then can send the data of 46 bytes in a foldback band 104.In this case, if the frame period of signal transmission is set to about 15ms, then transmission speed is about 24kbps.
At this, although if during the next frame arrived (time slot) but be foldback band 104 it be foldback band 104 for sending foldback data from from communication terminal 21 to transmission unit 1, then superposing that this foldback band 104 is judged as by the judging part 27 of terminal 22 can not stacked tape, is not used in the superposition of superposed signal.That is, superpose terminal 22 and the foldback band 104 of the transmission of the foldback data of not carrying out from communication terminal 21 to transmission unit 1 is brought as being suitable for superposition the stackable of superposed signal the superposition being used in superposed signal.Therefore, judging part 27 is configured to: if be foldback band 104 during identifying the frame arrived by transmission acceptance division 24 next one, then judge the transmission whether carrying out foldback data at this time zone, the foldback band 104 of the transmission not carrying out foldback data is judged as stackable band.
In the communication system of present embodiment, transmission unit 1 has frequency band and guarantees portion 18, this frequency band guarantee portion 18 in the transmit band 103 of signal transmission by signal transmission send for ensuing foldback band 104 is guaranteed for superposition superposed signal guarantee data.Frequency band is guaranteed that portion 18 synchronously sends from transport communication portion 11 with the transmit band 103 of signal transmission and is guaranteed data.Saidly guaranteeing that data are for sending by what forbid foldback data of carrying out from all communication terminals 21 in ensuing foldback band 104 the data guaranteed by ensuing foldback band 104 for superposing superposed signal at this, such as, is the pseudo-data be made up of the sky bag without specific meanings.
Superposition terminal 22 when in transmit band 103 by transmit acceptance division 24 receive from transmission unit 1 guarantee data time, the foldback band 104 after then this transmit band 103 is judged as stackable band.That is, immediately preceding to have sent from transmission unit 1 guarantee data transmit band 103 after (with the same frame of transmit band 103) foldback band 104 be not used in the transmission of foldback data, therefore this foldback band 104 is judged as stackable band by judging part 27.
In the present embodiment, transmission unit 1 uses the transmit band 103 of signal transmission that timed synchronization pulse is sent to multiple stage communication terminal 21 simultaneously every the set time (such as 1 second), and this timed synchronization pulse is used for obtaining time synchronized with communication terminal 21.The data that this timed synchronization pulse and transmission unit 1 send when conventional poll, different in the foldback request msg of interrupting sending in poll pattern, communication terminal 21 can not be made to send foldback data.That is, the transmission of foldback data is not carried out in the foldback band 104 of communication terminal 21 after the transmit band 103 receiving timed synchronization pulse.
Therefore, in the present embodiment, frequency band guarantees portion 18 by timed synchronization pulse as guaranteeing data.Thus, superposition terminal 22 is configured to: when receiving the timed synchronization pulse periodically sent from transmission unit 1 by signal transmission in transmit band 103, and the foldback band 104 after then this transmit band 103 is judged as stackable band.
Superposition Department of Communication Force 23 is sent the data sending part of data by superposed signal as being configured to and being configured to receive the data reception portion of the data sent by superposed signal from other superposition terminal 22 and playing function.Superposition Department of Communication Force 23 is configured to: only when being judged as that by judging part 27 the next foldback band arrived is stackable band, (receiving the ensuing foldback band 104 guaranteeing data) sends superposed signal.Superposition terminal 22, by synchronously only superposing superposed signal in stackable band with signal transmission like this, can avoid the interference between the communication of the first agreement using common order wire 10 and the communication of second protocol.
In addition, be also unsuitable for superposing superposed signal due to the impact etc. of the indicial response of the impact of high order harmonic component noise, the voltage reversal of accompaniment signal during the rising edge of signal transmission and trailing edge.Thus, being also judged as can not stacked tape by the avoidance time (such as 300 μ s) of the regulation behind the region of not carrying out in the foldback band 104 of the transmission of foldback data switching (rising edge) for judging part 27.
There is provided about to the power supply of superposition terminal 22, in the same manner as communication terminal 21, utilize by carrying out rectification from transmission unit 1 via the signal transmission that order wire 10 transmits and the mode (centralized power supply system) that stabilisation provides carries out providing the power supply of superposition terminal 22.But, be not limited to this structure, also can utilize by rectification is carried out to source power supply and the mode (local power mode) that stabilisation provides carry out to superposition terminal 22 power supply provide.
In addition, in the present embodiment, superposition terminal 22 directly can be communicated each other by superposed signal, possesses handling part 29, this handling part 29 is configured to, when being received the transmission data sent by superposed signal from other superposition terminal 22 by superposition Department of Communication Force 23, use these transmission data to carry out the process specified.Superposition terminal 22 is when sending data from the superposition Department of Communication Force 23 as data sending part by superposed signal, also the address of specific superposition terminal 22 can be specified to send data with mode of unicast, but substantially send data with broadcast mode at this.That is, multiple stage superposition terminal 22 is configured to: by receiving by arbitrary the transmission data that send with broadcast mode of superposition terminal 22, performs certain corresponding with this transmission data in advance process by handling part 29.
As an example of the process that handling part 29 performs, there is the process using the time information of the built-in clock portion of any one superposition terminal 22 to make superposition terminal 22 moment each other consistent (timing synchronization).In this case, each superposition terminal 22 has the clock portion (not shown) for measuring current time.At this, a certain superposition terminal 22 will represent that the time information of the current time measured by the clock portion of self sends as transmission data termly with broadcast mode.Other superposition terminal 22 receiving the transmission data be made up of time information makes the moment of clock portion consistent respectively by himself handling part 29 based on time information.
Thus, superposition terminal 22 can use superposed signal to make the moment consistent each other, thus the multiple stage in communication system can be made to superpose the whole in timing synchronization of terminal 22.In addition, when superposing terminal 22 and being built-in with GPS (Global Positioning System: global positioning system) receiver, the time clock feature of GPS can be used as clock portion.Such as, when only having at least one specific superposition terminal 22 to be built-in with GPS, as long as by this specifically superposition terminal 22 although the time information of the expression current time obtained from GPS to be sent to termly with broadcast mode to have timing unit (common timer function, such as, utilize the timer function of the clock of microcomputer) but other superposition terminal 22 of not built-in GPS as sending data, just can more correctly make the moment consistent.
As other example of the process that handling part 29 performs, there is the process using the time information from external device (ED) (not shown) to make superposition terminal 22 moment each other consistent.In this case, each superposition terminal 22 has the clock portion measuring current time, and at least one superposition terminal 22 has the interface (not shown) for connecting the external device (ED)s such as GPS receiving system.The superposition terminal 22 being connected with external device (ED), when getting the time information representing current time from external device (ED), makes the moment of clock portion consistent based on this time information, and is sent termly with broadcast mode as transmission data by time information.Other superposition terminal 22 receiving the transmission data be made up of time information makes the moment of clock portion consistent respectively by handling part 29 based on time information.
Thereby, it is possible to make the multiple stage in communication system superpose the whole in timing synchronization of terminal 22.And, in this case, the superposition terminal 22 being transfused to time information from external device (ED) as main frame, be not transfused to the superposition terminal 22 of time information from external device (ED) as from machine to carry out different actions, therefore unanimously can identify the master slave relation of multiple stage superposition terminal 22 about the moment.
As another example of the process that handling part 29 performs, the existence that there is superposition terminal 22 confirms process.In this case, the existence information at least comprising the address of himself sends as transmission data by each superposition terminal 22 termly.Superposition terminal 22, when receiving existence information from other superposition terminal 22, is confirmed by the survival condition of handling part 29 to the superposition terminal 22 of the address that this existence information comprises.That is, each superposition terminal 22 is judged as regular event for the superposition terminal 22 of the stored transmission source of the life received, and does not send raw stored superposition terminal 22 be judged as creating certain extremely for complete (during such as have passed through the existence judgement predetermined also).
Specifically, each superposition terminal 22 sends existence information with broadcast mode on one's own initiative with step once of per stipulated time (such as one day, one hour).In addition, each superposition terminal 22 stores by each superposition terminal 22 and receives up-to-date life stored time of reception from other superposition terminal 22, receive raw stored situation within the setting-up time (stipulated time+α) of regulation from this moment under, be judged as regular event, and the raw stored time of reception is upgraded.On the other hand, even if each superposition terminal 22 have passed through under setting-up time also fails to receive next raw stored situation from up-to-date life stored time of reception, be judged as that this superposition terminal 22 creates exception.
Thus, multiple stage superposition terminal 22 can be undertaken detecting whether there is abnormal existence confirmation by using superposition communication to carry out each other communicating.Thus, communication system without the need to introduce special management devices just can detect superposition terminal 22 whether there is exception.
In addition, each terminal 22 that superposes just sends existence information with step once of per stipulated time, therefore overlaps hardly from the transmission timing of multiple stage superposition terminal 22 transmission data (existence information).Wherein, repeat even if sometimes send raw stored transmission timing from multiple stage superposition terminal 22, communication system also can by adopting structure described later to avoid the superposed signal from multiple stage superposition terminal 22 interfering with each other.
According to above-mentioned structure, multiple stage superposition terminal 22 can by receiving by arbitrary the superposition terminal 22 transmission data that use superposed signal to send with broadcast mode, makes handling part 29 perform moment consistent, process such as confirmation of surviving.Thus, communication system stops without the need to the action of the fundamental system by using signal transmission, the moment just can carrying out superposing terminal 22 consistent, existence confirmation etc.
Then, illustrate for avoiding because multiple stage superposition terminal 22 sends data and superposed signal structure interfering with each other simultaneously at same stackable band.
Namely, multiple stage stacking apparatus 22 sends superposed signal to communicate respectively in the stackable band of signal transmission, therefore, when multiple stage superposition terminal 22 sends data simultaneously, there is the timing coincidence of transmission superposed signal and on order wire 10, produce the situation of superposed signal interference each other.Therefore, in the present embodiment, superposition terminal 22 is configured to: if the next foldback band 104 arrived is stackable bands, it not then the transmission carrying out sending data in this foldback band 104 immediately, but in this foldback band 104, first send reservation data to obtain the transmission route of the transmission data in the stackable band after next time, send data on this basis.In stackable band, can be only the superposition terminal 22 of the transmission route of the transmission data be endowed in this stackable band by the superposition terminal 22 of superposed signal transmission data, other superposition terminal 22 is prohibited to send data.
Be described in detail, superposition terminal 22 is configured to: if be judged as that the next foldback band 104 arrived is stackable bands by judging part 27, then in this foldback band 104, send reservation data by reservation portion 28, at this, reservation data is the data of the transmission route for the stackable the band later next time of above-mentioned foldback band 104 to be brought the transmission data obtained in this reservation band as reservation.Reservation portion 28 generates reservation data, sends this reservation data from superposition Department of Communication Force 23 by superposed signal with broadcast mode.
At this, reservation data at least comprises the address of the superposition terminal 22 as transmission source.Thus, the superposition terminal 22 of the transmission source of this reservation data is determined in the address that other superposition terminal 22 receiving the reservation data sent with broadcast mode by certain superposition terminal 22 can comprise according to reservation data.
The superposition Department of Communication Force 23 playing function as data sending part sends data by superposed signal utilizing reservation data to obtain in the reservation band (stackable band) of transmission route.In a word, the transmission that Department of Communication Force 23 carries out sending data in the stackable band utilizing reservation data to preengage in advance is superposed.Therefore, superpose terminal 22 and do not send superposed signal in the reservation band of self acquisition transmission route failure other superposition terminal 22 being imparted to the reservation band of transmission route etc.
Specifically, when a certain superposition terminal 22 in multiple stage superposition terminal 22 have sent reservation data by reservation portion 28, remaining superposition terminal 22 all receives this reservation data, the superposition terminal 22 of the transmission source of reservation data is given to the transmission route of the transmission data in ensuing stackable band.Therefore, impart in the stackable band of transmission route in the superposition terminal 22 of the transmission source to reservation data, the superposition terminal 22 receiving reservation data does not carry out the transmission of superposed signal.Such as, when the address superposition terminal 22 that to be address in the superposition terminal 22 of " 65 " ~ " 67 " be " 65 " have sent reservation data, address is the transmission route that the superposition terminal 22 of " 65 " obtains the transmission data in ensuing stackable band (reservation band).In other words, address is " 66 ", the superposition terminal 22 of " 67 " when received from address by superposition Department of Communication Force 23 be the reservation data of superposition terminal 22 of " 65 " time, make the transmission ensuing stackable band not being used in superposed signal, the superposition terminal 22 being " 65 " for address thus guarantees ensuing stackable band.
At this, in the present embodiment, superposing the transmission data that send of terminal 22 is the examples with the data length that can send in once stackable band.Such as, foldback band 104 is regular length, and the transmission data once sent by superposition terminal 22 are the data (fixed-length data or variable length data) within the scope of the regular length of foldback band 104.Thus, superposition terminal 22 obtains once the transmission route of the transmission data in stackable band (foldback band 104) with a reservation data, terminates the transmission sending data in the stackable band obtaining transmission route.
Below, the action superposed in the communication system of present embodiment terminal 22 sends data is described with reference to Fig. 5.
Transmission unit 1 uses signal transmission to communicate with between communication terminal 21 in the first frame F1 of signal transmission, sends as the timed synchronization pulse (S21 of Fig. 5) guaranteeing data in the transmit band 103 of the second frame F2 of signal transmission.Superposition terminal 22, when receiving timed synchronization pulse in the transmit band 103 at the second frame F2, sends reservation data (S22) by superposed signal with broadcast mode in the foldback band 104 of the second frame F2.
Afterwards, until the (n-1)th frame Fn-1 of signal transmission, between transmission unit 1 with communication terminal 21, use signal transmission to communicate, send as the timed synchronization pulse (S23) guaranteeing data in the transmit band 103 of the n-th frame Fn of signal transmission.In the second frame F2, utilizing reservation data to obtain the superposition terminal 22 of transmission route when receiving timed synchronization pulse in the n-th frame Fn, in the foldback band 104 of the n-th frame Fn, sending data (S24) by superposed signal.
According to communication system described above, superposition terminal 22, by synchronously only superposing superposed signal in the stackable band of signal transmission with signal transmission, can avoid the interference between the communication of the first agreement using common order wire 10 and the communication of second protocol.At this, superposition terminal 22 will be by guaranteeing the judgement of data (being timed synchronization pulse in the present embodiment) for stackable band, using wide for time among signal transmission long foldback band 104 as the transmission of stackable band for superposed signal, even the data that therefore data length is long also stackablely can bring transmission with one.Thus, even if superpose terminal 22 when the data that transmission data length is long also without the need to transmitting data finely, therefore, it is possible to do not transmit the long data of data length by superposed signal with reducing the transmission speed of data.
And, in the present embodiment, superposition terminal 22 not sends data immediately when the next foldback band 104 arrived becomes stackable band in this foldback band 104, but in this foldback band 104, first send reservation data to the transmission route of the transmission data in the stackable band after the next time obtaining this foldback band 104, in this stackable band, send data on this basis.Thus, in the communication system of present embodiment, the superposed signal interference each other (conflict (collision)) caused because multiple stage superposition terminal 22 sends data simultaneously at same stackable band can be avoided.
In addition, present embodiment communication system by transmission unit 1 every the timed synchronization pulse being used for carrying out time synchronized with communication terminal 21 that the set time sends be used as using foldback band 104 as stackable bring guarantee guarantee data.Thus, transmission unit 1 without the need to newly-generated special data be used as foldback band 104 is guaranteed for superposition superposed signal guarantee data, therefore, it is possible to the action of fundamental system is not had an impact and foldback band 104 is guaranteed for superposition superposed signal.Therefore, according to this communication system, can not change transmission unit 1 specification and using the foldback band 104 of signal transmission as the transmission of stackable band for superposed signal.
In addition, the frequency band of transmission unit 1 guarantees that portion 18 is not limited to by timed synchronization pulse as the structure guaranteeing data, also can be generate and send the special structure of guaranteeing data different from timed synchronization pulse.In this case, frequency band guarantees that portion 18 is not limited to periodically send the structure guaranteeing data, also can guarantee data in the timed sending determined according to the calendar be such as stored in storage part 14 (schedule), or guarantee data in the timed sending determined randomly.In addition, transmission unit 1 can be also following structure: the instruction accepted from upper stage arrangements such as energy-saving controllers 5 (with reference to Fig. 2) decides to send the timing or change calendar of guaranteeing data.
In addition, in the present embodiment, be illustrated for the situation that multiple stage superposition terminal 22 directly carries out communicating by superposed signal each other, but be not limited to this example, communication system also can be in superposition terminal 22 and the structure of being undertaken by superposed signal between transmission unit 1 communicating.
In this case, transmission unit 1 possesses and is configured to and superposes between terminal 22 by the superposition Department of Communication Force 16 (with reference to Fig. 1) that superposed signal carries out communicating, be configured to can not only with between communication terminal 21, can also communicate with superposing between terminal 2.Thus, transmission unit 1 such as can control the load (ligthing paraphernalia 3) being connected to the first control terminal 212 according to the supervision input produced by the second monitoring terminal 221.
Specifically, the storage part 14 of transmission unit 1 stores the control table making the address of the second monitoring terminal 221 (inherent address of transducer) corresponding with the address (inherent address of such as relay) of the second control terminal 222.In addition, in control table, the address of the first monitoring terminal 211 both can have been made corresponding with the address of the second control terminal 222, or the address of the second monitoring terminal 221 also can be made corresponding with the address of the first control terminal 212.
In the present embodiment, the output data being connected to the sensor device (imageing sensor, power measurement unit 91 etc.) 9 of self are sent to transmission unit 1 as transmission data by the second monitoring terminal 221.In these said transmission data except comprising the output data (presence or absence etc. of image, power information, temperature, humidity, CO2 amount, people) as the sensor device 9 monitoring input, also comprise the address information of the second monitoring terminal 221 as transmission source, represent the length information, temporal information, positional information etc. of data length.That is, the superposition Department of Communication Force 16 of transmission unit 1 receives by the stackable band of signal transmission the transmission data based on superposed signal sent from the second monitoring terminal 221.Its result, the output data (monitoring input) being connected to the sensor device 9 of the second monitoring terminal 221 can obtain as transmission data by transmission unit 1.
In addition, transmission unit 1 sends the control data corresponding with superposed signal based on the transmission data obtained from the second monitoring terminal 221 to the second control terminal 222, controls the load (ligthing paraphernalia 3) being connected to the second control terminal 222.The corresponding relation of the second monitoring terminal 221 and the second control terminal 222 sets substantially in control table, but is not limited thereto, and also can include the address of the load (ligthing paraphernalia 3) as control object in transmission data.Further, also can send in data include such as with brightness adjustment control, mixing colours the relevant concrete control content such as to control.
In addition, the superposed signal of superposition on transmission unit 1 is used in signal transmission foldback band 104 from control data to the second control terminal 222 when sending, therefore needs to avoid in foldback band 104 from the interference between the foldback data of communication terminal 21 and control data (superposed signal).Therefore, it is desirable that, transmission unit 1 by have sent guarantee data transmit band 103 after foldback band 104 and the foldback band 104 which superposition terminal 22 does not all give transmission route is used in the transmission of control data.
In addition, at this, exemplified with the action of communication system when controlling the load (ligthing paraphernalia 3) being connected to the second control terminal 222 according to the supervision input produced by the second monitoring terminal 221, but not as the necessary structure of communication system to the control of load.That is, such as, when being applied to the system of supervision input of only collecting sensor equipment 9, as long as transmission unit 1 can obtain the structure of the transmission data from the second monitoring terminal 221, control data is sent optional.In this case, in the example depicted in figure 1, superposition terminal 22 (the second monitoring terminal 221) is at least connected.In addition, the communication system of Fig. 1 also can connect a communication terminal 21.In addition, in FIG, be built in the structure of transmission unit 1, but be not limited thereto exemplified with superposition Department of Communication Force 16, superposition Department of Communication Force also can be set to and transmission unit 1 split, and is electrically connected with transmission unit 1.
(execution mode 2)
In the communication system of present embodiment, when have sent reservation data from multiple stage superposition terminal 22 at same stackable band, for this multiple stage superposition terminal 22, from more early sending the superposition terminal 22 of reservation data, more preferably give the transmission route in reservation band, be different from execution mode 1 in this.That is, in the present embodiment, superposition terminal 22 more than two have sent reservation data in same stackable band, preferential transmission route of giving in later stackable band (reservation band) next time from the transmission of reservation data timing superposition terminal 22 early.Below, common mark is marked to the structure identical with execution mode 1, suitably omits the description.
That is, each superposition terminal 22 can send the reservation data of himself and receive the reservation data sent by other superposition terminal 22, therefore, it is possible to grasp both transmission timings of the transmission timing of the reservation data of himself and the reservation data of other superposition terminal 22.Thus, in each superposition terminal 22, for the multiple stage superposition terminal 22 that have sent reservation data in same stackable band, the precedence relationship (sequentially) of the transmission timing of reservation data can be grasped.
At this, as the method for more preferably giving transmission route from more early sending the superposition terminal 22 of reservation data, there are two kinds of methods.
First method is as follows: only give transmission route to the superposition terminal 22 that have sent reservation data at first that have sent at a stackable band in the multiple stage superposition terminal 22 of reservation data.In the method, the transmission of the reservation data of himself timing superpose the reservation data of terminal 22 by each superposition terminal 22 that have sent reservation data transmission timing with other contrasts, and is only the transmission route in can obtaining reservation at first and being with in the transmission timing of himself.That is, ranked second in later superposition terminal 22 in the timing that have sent reservation data, make ensuing stackable band not to be used in the transmission sending data, the superposition terminal 22 thus for have sent reservation data at first guarantees ensuing stackable band.
Second method is as follows: superpose the whole of terminal 22 for the multiple stage that have sent reservation data at a stackable band, distribute the transmission route in stackable band.In the method, the transmission of the reservation data of himself timing superpose the reservation data of terminal 22 by each superposition terminal 22 that have sent reservation data transmission timing with other contrasts, and superposes for this multiple stage the order that terminal 22 grasp have sent reservation data.In this case, for this multiple stage superposition terminal 22, from more early sending the superposition terminal 22 of reservation data, give transmission route in order.Such as, to the transmission timing superposition terminal 22 at first of reservation data, the transmission route from the above-mentioned stackable transmission data taken up first stackable band (a stackable band then after an above-mentioned stackable band) is given.To the superposition terminal 22 that the transmission timing of reservation data ranked second, give the transmission route of the transmission data in second stackable band.That is, if have sent himself the transmission timing row the n-th of reservation data of each superposition terminal 22 of reservation data at a stackable band, then obtain from the transmission route of the above-mentioned stackable transmission data taken up the n-th stackable band based on reservation data.
In addition, be no matter any in above-mentioned two kinds of methods, superposition terminal 22 all uses superposed signal transmission reservation data, and therefore when the transmission timing coincidence of reservation data, likely superposed signal is interfering with each other and normally cannot receive reservation data.
Therefore, in the present embodiment, reservation portion 28 is configured to the transmission timed sending reservation data that predetermining for each superposition terminal 22 in stackable band.Specifically, each superposition terminal 22 based on the address of himself in advance by the stand-by period determined from the sart point in time of stackable band is to the transmission of reservation data.At this, if the time sent needed for reservation data is set to unit interval Ta, then based on have sent reservation data each superposition terminal 22 address to this respectively superposition terminal 22 distribute and superpose with other stand-by period that terminal 22 at least differs unit interval Ta.Such as, if set the shortest stand-by period as X (X>0), then the n-th stand-by period was X+Ta × (n-1), was n >=1 at this n.In addition, for determining that the address of stand-by period is the address for identifying superposition terminal 22.Such as, set in address less (or larger) mode that then stand-by period is shorter.
Therefore, such as when the address of multiple stage superposition terminal 22 is respectively " 65 " ~ " 67 ", by address be the superposition terminal 22 of " 65 ", address is the superposition terminal 22 of " 66 ", address is the such order of the superposition terminal 22 of " 67 ", sets the transmission timing of reservation data with respectively staggering unit interval Ta.Stackable band as described above after the avoidance time (such as 300 μ s) of the regulation lighted from the rising time of foldback band 104, therefore superpose terminal 22 and light delay " (address-64) × Ta+ avoids the time " from the rising time of foldback band 104 and send reservation data afterwards.
That is, as shown in Figure 6, when transmission unit 1 is sent as when guaranteeing the timed synchronization pulse of data (S31) by the transmit band 103 of the second frame F2 of signal transmission, superpose terminal 22 and send reservation data (S32) by the foldback band 104 of the second frame F2.Now, when the multiple stage superposition terminal 22 being respectively " 65 " ~ " 67 " from address sends reservation data, the transmission timing of reservation data for address be the superposition terminal 22 of " 65 ", address is the superposition terminal 22 of " 66 ", address is the such order of the superposition terminal 22 of " 67 ".
Afterwards, until the (n-1)th frame Fn-1 of signal transmission, between transmission unit 1 with communication terminal 21, use signal transmission to communicate, send as the timed synchronization pulse (S33) guaranteeing data in the transmit band 103 of the n-th frame Fn of signal transmission.The address that have sent reservation data in the second frame F2 be at first the superposition terminal 22 of " 65 " when receiving timed synchronization pulse in the n-th frame Fn, in the foldback band 104 of the n-th frame Fn, send data (S34) by superposed signal.
Thus, the transmission timing of the reservation data of multiple stage superposition terminal 22 can not overlap, and superposed signal can be avoided interfering with each other and normally cannot receive the state of affairs of reservation data.In addition, multiple stage superposition terminal 22 sends reservation data in order in same stackable band, therefore, it is possible to send the reservation data from multiple stage superposition terminal 22 more efficiently.
In addition, as other example, reservation portion 28 also can be configured to the transmission timed sending reservation data determined randomly for each superposition terminal 22 in stackable band.Specifically, each superposition terminal 22 stand-by period of using random number to decide from the sart point in time of stackable band is to the transmission of reservation data when sending reservation data.That is, the stand-by period calculates by making random number be multiplied by coefficient (such as 10 μ s).At this, stackable band as described above after the avoidance time (such as 300 μ s) of the regulation lighted from the rising time of foldback band 104, therefore superpose terminal 22 and light delay " random number × coefficient+avoidance time " from the rising time of foldback band 104 and send reservation data afterwards.
In this case, before the transmission of reservation portion 28 reservation data lighting after the stand-by period from the time started of stackable band, first judge whether other superposition terminal 22 sends reservation data, if sent, shelves the transmission of reservation data.Now, reservation portion 28 confirms the remaining time of stackable band, if having the remaining time being enough to send another reservation data again after being sent completely of the reservation data sent, then after being sent completely of the reservation data sent, oneself sends reservation data.At this, reservation portion 28 also after confirming that the transmission of the reservation data of carrying out from other superposition terminal 22 terminates, can use random number to recalculate the stand-by period, after the stand-by period obtained, is sending reservation data.
Flow chart with reference to Fig. 7 carrys out the action in simple declaration reservation portion 28 in this case.
Reservation portion 28, when stackable band starts, first uses random number to calculate the stand-by period (S41), is judging whether the transmission (S42) that there is the reservation data of carrying out from other superposition terminal 22 after the stand-by period.If there is no superpose the transmission (S42: "Yes") of the reservation data that terminal 22 is carried out from other, then reservation portion 28 sends reservation data (S43).On the other hand, if there is the transmission (S42: "No") of reservation data carried out from other superposition terminal 22, then reservation portion 28 confirms (S44) more than needed that judge whether the remaining time of this stackable band to be enough to send reservation data again.At this, if remaining time (S44: "Yes") not more than needed, then the transmission (S45) of the reservation data in this stackable band is shelved in reservation portion 28.On the other hand, if had remaining time (S44: "No") more than needed, then reservation portion 28 waits for being sent completely (S46) of the reservation data of carrying out from other superposition terminal 22, turns back to the computing (S41) of stand-by period.
Thereby, it is possible to prevent multiple stage from superposing the transmission timing coincidence of reservation data of terminal 22, thus superposed signal can be avoided interfering with each other and normally cannot receive the state of affairs of reservation data.And by determining the stand-by period randomly, what multiple stage superposition terminal 22 sent reservation data occurs in sequence variation, therefore multiple stage superposition terminal 22 is given liberally to the chance of transmission reservation data.Therefore, communication system can avoid following situation: specific superposition terminal 22 first sends reservation data, and the transmission route sending data thus is always given to specific superposition terminal 22 by concentrated.
And, if have enough more than needed in the remaining time of stackable band after being sent completely of other superposition terminal 22 reservation data of carrying out, then reservation portion 28 oneself sends reservation data in same stackable band, therefore, it is possible to a stackable band to be used in the transmission of the reservation data of carrying out from multiple stage superposition terminal 22.Thus, communication system can send the reservation data from multiple stage superposition terminal 22 more efficiently.
In addition, when adopting above-mentioned second method, if the data length sending data is shorter, then the stackable band guaranteed as reservation band also can be used in the transmission of the transmission data of carrying out from multiple stage superposition terminal 22.Therefore, reservation data, except comprising the address as the superposition terminal 22 of transmission source, also comprises the length information of the data length of the transmission data representing the sending object become in reservation band.And, to the multiple stage superposition terminal 22 that have sent reservation data at same stackable band with the summation of the data length represented by the length information making their reservation data and comprise be regulation permission length below mode divide into groups.The transmission route in same reservation band is given to the superposition terminal 22 belonging to same group.
Specifically, for each superposition terminal 22, the data length represented by the length information comprise the reservation data of transmission is added successively, is incorporated in by the data length of its summation till allowing below length and is identified as same group.That is, transmission route is given by the order that have sent reservation data to multiple stage superposition terminal 22, therefore by the sending order of reservation data, be incorporated in the summation of the data length sending data and allow multiple stage superposition terminal 22 in the scope of length to be classified as same group.The superposition terminal 22 being classified as same group obtains same transmission route of preengaging in band, therefore in same stackable band (reservation band), sends data by the sending order transmission of reservation data.
Such as, as shown in Figure 8, when transmission unit 1 sends as when guaranteeing the timed synchronization pulse of data (S51) in the transmit band 103 of the second frame F2 of signal transmission, superposition terminal 22 sends reservation data (S52) in the foldback band 104 of the second frame F2.Now, suppose to be respectively from address " 65 ", two superposition terminals 22 of " 66 " send reservation data in order, from the summations of the data length of the transmission data of these two superposition terminals 22 for allowing below length.
Afterwards, until the (n-1)th frame Fn-1 of signal transmission, between transmission unit 1 with communication terminal 21, use signal transmission to communicate, send as the timed synchronization pulse (S53) guaranteeing data in the transmit band 103 of the n-th frame Fn of signal transmission.The address that have sent reservation data in the second frame F2 be at first the superposition terminal 22 of " 65 " when receiving timed synchronization pulse in the n-th frame Fn, in the foldback band 104 of the n-th frame Fn, send data (S54) by superposed signal.And, the superposition terminal 22 that address is " 66 " when receiving timed synchronization pulse in the n-th frame Fn, is, after being sent completely of the superposition terminal 22 of " 65 " the transmission data of carrying out, send data (S55) by superposed signal from address in the foldback band 104 of the n-th frame Fn.
According to this structure, multiple stage superposition terminal 22 can send data in once stackable band, therefore with only send compared with a situation sending data in once stackable band, stackable band can be used in efficiently the transmission of transmission data.
In addition, superposition terminal 22 when the data length sending data long and cannot send in once stackable band, with the end correspondingly interrupt communication of this stackable band, in the remaining data of upper once stackable band transmission.That is, superpose terminal 22 send send data time by transmission Data Segmentation be the length that can superpose in stackable band.In this case, also can be configured to: reservation data comprises the frame information representing and send the quantity of the stackable band needed for data, give the transmission route in the stackable band (reservation band) of the quantity corresponding to frame information to superposition terminal 22.
Thus, superposition terminal 22 can obtain the transmission route of the transmission data in the stackable band of the quantity sent needed for data, therefore, it is possible to use the plurality of stackable bringing to send data.At this, as long as at least one party in the information of the quantity of stackable band needed for frame information direct representation and above-mentioned length information.That is, because length information is the information representing the data length sending data, as long as the data length that therefore can send at a stackable band is known, the quantity of the stackable band sent needed for data just can be determined according to the relation with this known data length.
Such as, as shown in Figure 9, when transmission unit 1 sends as when guaranteeing the timed synchronization pulse of data (S61) in the transmit band 103 of the first frame F1 of signal transmission, superposition terminal 22 sends reservation data (S62) in the foldback band 104 of the first frame F1.Afterwards, until the (n-1)th frame Fn-1 of signal transmission, between transmission unit 1 with communication terminal 21, use signal transmission to communicate, send as the timed synchronization pulse (S63) guaranteeing data in the transmit band 103 of the n-th frame Fn of signal transmission.In the first frame F1, have sent the superposition terminal 22 of reservation data when receiving timed synchronization pulse in the n-th frame Fn, in the foldback band 104 of the n-th frame Fn, being sent a part (S64) for data by superposed signal.
Afterwards, until the 2n-1 frame F2n-1 of signal transmission, use signal transmission to communicate between transmission unit 1 with communication terminal 21, send as the timed synchronization pulse (S65) guaranteeing data in the transmit band 103 of the 2n frame F2n of signal transmission.In the first frame F1, have sent the superposition terminal 22 of reservation data when receiving timed synchronization pulse in 2n frame F2n, in the foldback band 104 of 2n frame F2n, being sent the remainder (S66) of data by superposed signal.
According to this structure, even long bag etc. can not be incorporated in the transmission data in a stackable band, superposition terminal 22 also can use the multiple stackable band (reservation band) utilizing reservation data to obtain transmission route to be sent.
Other 26S Proteasome Structure and Function is identical with execution mode 1.
(execution mode 3)
The communication system of present embodiment is as avoiding from the superposed signal of multiple stage superposition terminal 22 structure interfering with each other, superposition Department of Communication Force 23 with the not using reservation data transmission data of superposition terminal 22, are different from the communication system of execution mode 1 in this.Below, common mark is marked to the structure identical with execution mode 1, suitably omits the description.
In the present embodiment, superposition Department of Communication Force 23 is configured to: in stackable band, send data in the transmission timed sending predetermined for each superposition terminal 22, if other superposition terminal 22 sends data, not transmission data.That is, superpose terminal 22 to be configured to: be not the transmission carrying out sending data immediately when becoming stackable band, but send data in the transmission timed sending predetermined for each superposition terminal 22 in stackable band.
Specifically, each superposition terminal 22 based on the address of self in advance by the stand-by period determining from the sart point in time of stackable band (namely receiving the ensuing foldback band 104 guaranteeing data) to the transmission sending data.At this, based on the address of each superposition terminal 22 each superposition terminal 22 distributed and superpose with other stand-by period that terminal 22 at least differs Tb time of delay.Such as, if set the shortest stand-by period as Y (Y>0), then the n-th stand-by period was Y+Tb × (n-1), was n >=1 at this n.Such as when the address of multiple stage superposition terminal 22 is respectively " 65 " ~ " 67 ", by address be the superposition terminal 22 of " 65 ", address is the superposition terminal 22 of " 66 ", address is the such order of the superposition terminal 22 of " 67 ", sets the transmission timing sending data with respectively staggering Tb time of delay.Stackable band after avoidance time (the such as 300 μ s) Tc of the regulation lighted from the rising time of foldback band 104, therefore superpose terminal 22 and light delay " (address-65) × Tb+Tc " from the rising time of foldback band 104 and send data afterwards.
That is, superposing terminal 22 when receiving timed synchronization pulse in the transmit band 103 at signal transmission, in the foldback band 104 of same frame, sending data by superposed signal.Now, when the multiple stage superposition terminal 22 that address is respectively " 65 " ~ " 68 " sends data, the transmission timing sending data is respectively staggered Tb time of delay as shown in Figure 10.That is, as shown in Figure 10, address be " 65 " if superposition terminal 22 there are the data that send in foldback band 104, then from the rising edge of foldback band 104, start the transmission sending data after " Tc ".Address for " 66 " if superposition terminal 22 there are the data that send in foldback band 104 and other superposes terminal 22 (address is the superposition terminal 22 of " 65 ") in foldback band 104, does not send data, then from the rising edge of foldback band 104, start the transmission sending data after " Tc+Tb ".Similarly, address for " 67 " if superposition terminal 22 there are the data that send in foldback band 104 and other superposes terminal 22 (address is the superposition terminal 22 of " 65 " and " 66 ") in foldback band 104, does not send data, then from the rising edge of foldback band 104, start the transmission sending data after " Tc+2Tb ".Address for " 68 " if superposition terminal 22 there are the data that send in foldback band 104 and other superposes terminal 22 (address is the superposition terminal 22 of " 65 " ~ " 67 ") in foldback band 104, does not send data, then after " Tc+3Tb " the rising edge from foldback band 104, start the transmission sending data.
At this, superposition terminal 22 cannot transmission data when other superposition terminal 22 is sending data, therefore shelve the transmission of transmission data.Thus, when as described above by address be " 65 ", " 66 ", " 67 ", " 68 " order determine send data transmission timing, be that the transmission data of the superposition terminal 22 of " 65 " are prepreerence from address.That is, address be " 66 ", " 67 ", " 68 " superposition terminal 22 in address be only " 65 " superposition terminal 22 send data time can transmission data.
According to the communication system of present embodiment described above, superposition terminal 22 sends data in the transmission timed sending predetermined for each superposition terminal 22, does not therefore use reservation data and multiple stage can be avoided to superpose the transmission timing coincidence of terminal 22 superposed signal each other.Thus, superposed signal interference each other (conflict) can be avoided.In addition, compared with sending the structure of data after sending reservation data, have the following advantages: the time required till sending data can be shortened to, the time lag sent till data can be shortened to.
Other 26S Proteasome Structure and Function is identical with execution mode 1.
