As shown in the figure, in addition to the configuration described in the above embodiment, the multipoint traffic sign control system 100 described in the third embodiment differs from the above embodiment in that the traffic log group 120 included in the present creation can be connected. At least one external device 130 or at least one traffic signal 140, and the control slave device 121 drives at least one external device 130 or at least one traffic signal 140, or controls the slave device 121 according to the control signal 101 transmitted by the control host 110.

請參閱第4圖,其係為本創作之多點交通號誌控制系統之第四實施例之方塊圖。如圖所示,除上述實施例所述之配置之外,第四實施例所述之多點交通號誌控制系統100與上述實施例差異在於,至少一交通號誌組120之數量可為複數個,而控制主機110與複數個交通號誌組120則以串聯方式相互連接。Please refer to FIG. 4, which is a block diagram of a fourth embodiment of the multi-point traffic control system of the present invention. As shown in the figure, in addition to the configuration described in the above embodiments, the multipoint traffic control system 100 described in the fourth embodiment differs from the above embodiment in that the number of at least one traffic ok group 120 can be plural. And the control host 110 and the plurality of traffic ok groups 120 are connected to each other in series.

更詳細地說,複數個交通號誌組120以至少一訊號線與控制主機110串聯連接;其中,複數個交通號誌組120中之至少一個的控制子機121接收控制訊號101後,將依據控制訊號101驅動其所連接之燈號桿組122顯示對應之燈號。其中,燈號桿組122係具有複數個發光單元,並藉由複數個發光單元的組合顯示各種燈號;此外,於本案之各實施例中,控制主機110所發出的控制訊號101將傳送給所有交通號誌組120,但並非同時所有的交通號誌組120於接收控制訊號101後皆會顯示燈號,而是複數個交通號誌組120中對應控制訊號101的至少一個交通號誌組120會依據控制訊號101而顯示對應的燈號。In more detail, the plurality of traffic ok groups 120 are connected in series with the control host 110 by at least one signal line; wherein, after the control slave unit 121 of at least one of the plurality of traffic ok groups 120 receives the control signal 101, The control signal 101 drives the set of light poles 122 to which it is connected to display the corresponding light number. The light bar group 122 has a plurality of light emitting units, and various light signals are displayed by a combination of a plurality of light emitting units. Further, in various embodiments of the present invention, the control signal 101 sent by the control host 110 is transmitted to All of the traffic signal groups 120, but not all of the traffic signal groups 120 will display the light number after receiving the control signal 101, but at least one traffic number group corresponding to the control signal 101 in the plurality of traffic code groups 120. 120 will display the corresponding light number according to the control signal 101.

承上述,於本創作之各實施例中,多點交通號誌控制系統100於實際應用時,將由控制主機110產生控制訊號101,並分別經由至少一訊號線將控制訊號101傳送至其所連接之至少一個交通號誌組120之控制子機121,亦或是經由至少一訊號線將控制訊號101傳送至其所串聯之各交通號誌組120之控制子機121,而對應控制訊號101的交通號誌組120之控制子機121將會依據控制訊號101而驅動燈號桿組122顯示對應的燈號。而,若本創作以至少一訊號線串聯控制主機110及複數個交通號誌組120時,當複數個交通號誌組120中的其中一個交通號誌組120之一端斷訊時,仍可由另一端接收控制訊號101並據以作動。然,上述係為本創作之部分示例,不應以此為限。In the above embodiments, in the actual application, the multi-point traffic control system 100 will generate the control signal 101 by the control host 110 and transmit the control signal 101 to the connected terminal via at least one signal line. The control sub-machine 121 of the at least one traffic locomotive group 120 transmits the control signal 101 to the control sub-machine 121 of each of the traffic locomotive groups 120 connected thereto via at least one signal line, and corresponds to the control signal 101. The control slave 121 of the traffic log group 120 will drive the light bar set 122 to display the corresponding light number according to the control signal 101. However, if the present invention controls the host 110 and the plurality of traffic ok groups 120 in series by at least one signal line, when one of the plurality of traffic ok groups 120 is disconnected, one of the traffic trad One end receives the control signal 101 and acts accordingly. However, the above is a partial example of this creation and should not be limited to this.

請參閱第5圖,其係為本創作之多點交通號誌控制系統之第五實施例之方塊圖。如圖所示,除上述實施例所述之配置之外,第五實施例所述之多點交通號誌控制系統100與上述實施例差異在於,複數個控制子機121更可分別包含驅動模組123,複數個驅動模組123中的至少一個驅動模組123依據控制訊號101而驅動燈號桿組122顯示燈號。Please refer to FIG. 5, which is a block diagram of a fifth embodiment of the multi-point traffic control system of the present invention. As shown in the figure, in addition to the configuration described in the above embodiment, the multipoint traffic control system 100 of the fifth embodiment differs from the above embodiment in that a plurality of control slaves 121 respectively include drive modes. The group 123, at least one of the plurality of driving modules 123 drives the light bar group 122 to display the light number according to the control signal 101.

更進一步地,控制主機110可包含主控制器111以產生控制訊號101,進而由複數個驅動模組123分別偵測各燈號桿組122,並對應產生各燈號桿組122之狀態訊號102,並將其傳送至主控制器111,即主控制器111將接收由複數個驅動模組123所產生之複數個狀態訊號102。其中,驅動模組123可為雙向性三極閘流體(Triac),各驅動模組123皆可獨立控制且具有偵測燈號桿組122狀態之功能,故可將對應燈號桿組122之狀態訊號102回傳給主控制器111,且驅動模組123可增加觸動裝置(輸入裝置),而不需連接到控制主機110,此外,各驅動模組123可單獨進行維修,且工程配線簡易,僅需兩條電力線(AC線)及兩條訊號線即可;而主控制器111則可為32位元工業用的處理器,其具有抗高溫、雜訊之特性,且可整合上電復位、欠壓復位及高壓檢測之功能,並可藉由收集各驅動模組123所產生之狀態訊號102而進行分析整理,另一方面,主控制器111亦可包含通用序列匯流排(Universal Serial Bus , USB)介面。然,上述僅為舉例,並不以此為限。Further, the control host 110 may include the main controller 111 to generate the control signal 101, and then the plurality of driving modules 123 respectively detect each of the light bar sets 122, and correspondingly generate the status signals 102 of the respective light bar sets 122. And transmitting it to the main controller 111, that is, the main controller 111 will receive a plurality of status signals 102 generated by the plurality of driving modules 123. The driving module 123 can be a bidirectional triac fluid (Triac), and each driving module 123 can be independently controlled and has the function of detecting the state of the lamp bar group 122, so that the corresponding lamp bar group 122 can be The status signal 102 is transmitted back to the main controller 111, and the driving module 123 can add the touch device (input device) without connecting to the control host 110. In addition, each driving module 123 can be separately repaired, and the engineering wiring is simple. Only two power lines (AC lines) and two signal lines are needed; and the main controller 111 can be a 32-bit industrial processor, which has the characteristics of high temperature resistance and noise, and can be integrated with power. The function of the reset, the undervoltage reset and the high voltage detection can be analyzed and collected by collecting the status signals 102 generated by the drive modules 123. On the other hand, the main controller 111 can also include the universal serial bus (Universal Serial) Bus, USB) interface. However, the above is only an example and is not limited thereto.

承上述,本創作之複數個控制子機121所包含之驅動模組123可預先設定預設值,因此,於複數個控制子機121中的其中一個控制子機121未接收到控制訊號101(即驅動模組123偵測到與主控制器111連線)時,未收到控制訊號101之控制子機121所包含之驅動模組123將依據預設值驅動燈號桿組122顯示燈號;換言之,當控制主機110無法正常運作時,各交通號誌組120仍可獨立運作簡易的燈號。然,上述示例說明係以具有複數個交通號誌組120且與控制主機110串聯為例,其與控制主機110與單一交通號誌組120連接,或是控制主機110分別與複數個交通號誌組120連接等作動方式及其原理皆為相同,僅連接方式有所相異,故針對控制主機110與單一交通號誌組120連接,或是控制主機110分別與複數個交通號誌組120連接之示例說明便不予以贅述。In the above, the driving module 123 included in the plurality of control sub-machines 121 of the present invention can preset the preset value. Therefore, one of the plurality of control sub-machines 121 does not receive the control signal 101 ( When the driving module 123 detects the connection with the main controller 111, the driving module 123 included in the control sub-machine 121 that has not received the control signal 101 will drive the light bar group 122 to display the light number according to the preset value. In other words, when the control host 110 is not functioning properly, each traffic log group 120 can still operate a simple light signal independently. However, the above example is illustrated by having a plurality of traffic ok groups 120 and being connected in series with the control host 110, which is connected to the control host 110 and the single traffic ok group 120, or the control host 110 and a plurality of traffic identities respectively. The group 120 connection and the like and the principle thereof are all the same, and only the connection manners are different, so the control host 110 is connected to the single traffic number group 120, or the control host 110 is connected to the plurality of traffic number groups 120, respectively. The example description will not be repeated.
