Description
Technical Field
[0001] This application relates to the field of signal technology, and in particular to a relay-based combined signal device. Background Technology
[0002] In the field of traffic signal control, conventional signal controllers typically use simple signal display methods, such as the common red, yellow, and green three-color lights. Their functions and display modes are relatively fixed, and they are mainly used for general traffic control, such as instructing vehicles to pass, wait, and stop.
[0003] However, in some special traffic scenarios, such as temporary construction sections, temporary traffic control areas, areas where major events are held, or intersections with special control needs, it may be necessary to indicate information such as traffic diversion in different directions, different traffic permissions for different lanes, temporary road occupancy, or temporary road opening. However, existing conventional traffic signals cannot provide clear and explicit instructions for such complex needs. Utility Model Content
[0004] In view of the above-mentioned problems of the prior art, this application provides a relay-based combined signal device, which can realize complex signal display functions by connecting the phase output of the signal and the relay in different ways according to different scenario requirements without adjusting the signal control program, so as to meet the traffic signal indication and traffic control requirements under special needs.
[0005] To achieve the above objectives, the first aspect of this application provides a relay-based combined signal device, comprising: a signal body having multiple phase output terminals; a relay having a coil side and a contact side, one end of the coil side being connected to any phase output terminal, the other end of the coil side being connected to a neutral line, and a static contact of the contact side being connected to the phase output terminal to be controlled; and a signal lamp connected to a dynamic contact of the relay contact side.
[0006] As described above, by connecting a relay to the phase output channel of the signal controller, the phase output of the signal controller can be connected differently through the relay, thereby enabling the output of various different signal light combinations without adjusting the control logic, thus meeting the needs of complex and ever-changing application scenarios.
[0007] As one implementation of this aspect, one end of the coil side is connected to an arbitrary phase output terminal, including: one end of the coil side is connected to the green light control line of the first phase output terminal.
[0008] As one implementation of this aspect, the static contact on the contact side is connected to the phase output terminal to be controlled, including:
[0009] The first static contact on the contact side is connected to the red light control line of the second phase, and the second static contact on the contact side is suspended; wherein, the first static contact and the second static contact are switched through a first dynamic contact; the third static contact on the contact side is connected to the yellow light control line of the second phase, and the fourth static contact on the contact side is connected to the yellow light control line of the third phase; wherein, the third static contact and the fourth static contact are switched through a second dynamic contact; the fifth static contact on the contact side is connected to the green light control line of the second phase, and the sixth static contact on the contact side is suspended; wherein, the fifth static contact and the sixth static contact are switched through a third dynamic contact.
[0010] As one implementation of this aspect, the signal light is connected to a dynamic contact on the relay contact side, including: a first dynamic contact connected to the live wire of the red light in the signal light; a second dynamic contact connected to the live wire of the yellow light in the signal light; and a third dynamic contact connected to the live wire of the green light in the signal light.
[0011] As one implementation of this aspect, the first static contact, the third static contact, and the fifth static contact are normally open contacts, which indicate that they are connected when energized and disconnected when de-energized; the second static contact, the fourth static contact, and the sixth static contact are normally closed contacts, which indicate that they are disconnected when energized and connected when de-energized.
[0012] As described above, the above connection enables a traffic light in a certain direction to alternate between red, yellow, and green lights in the first time period and continuously output flashing yellow lights in the second time period, thus achieving different light color outputs without changing the control logic.
[0013] As one implementation of this aspect, one end of the coil side is connected to any phase output terminal, including: one end of the coil side is connected to the green light control line of the fourth phase output terminal.
[0014] As one implementation of this aspect, the static contact on the contact side is connected to the phase output terminal to be controlled, including: the seventh static contact on the contact side is connected to the yellow light control line of the fifth phase, and the eighth static contact on the contact side is connected to the yellow light control line of the fourth phase; wherein, the seventh static contact and the eighth static contact are switched through the fourth dynamic contact.
[0015] As one implementation of this aspect, the signal light is connected to a dynamic contact on the relay contact side, including: the fourth dynamic contact is connected to the live wire of the yellow light in the signal light.
[0016] As one implementation of this aspect, it also includes: the live wire of the red light in the signal light is connected to the red light control line of the fourth phase.
[0017] As one implementation of this aspect, the seventh static contact is a normally closed contact, and the eighth static contact is a normally open contact. The normally open contact indicates that it is conducting in the energized state and disconnected in the de-energized state; the normally closed contact indicates that it is disconnected in the energized state and conducting in the de-energized state.
[0018] As described above, the connection can enable a signal light in a certain direction to display a red light in the first stage and a flashing yellow light in other stages. Before the yellow light switches to red, the yellow light remains on. Based on this circuit, complex light color output is achieved.
[0019] As one implementation of this aspect, it also includes: a housing, wherein the signal generator body and the relay are disposed inside the housing.
[0020] Therefore, by housing the signal controller and relay inside the enclosure, stable operation in outdoor environments can be ensured. Attached Figure Description

[0028] The embodiments of this application will now be described in detail with reference to the accompanying drawings. First, the application scenarios of the relay-based combined signal device provided in the embodiments of this application will be introduced.
[0029] The combined traffic signal device provided in this application can be applied to traffic intersections that require complex light color combinations, such as large intersections, large roundabouts, and multi-directional overpasses. Through the interaction between the dynamic and static contacts on the relay contact side of the device in this application, different connection relationships can be achieved, thereby enabling the traffic signal to output multiple phase combinations, thus realizing complex traffic light combinations to indicate traffic flow in different directions.
[0030] It should be understood that the above application scenarios are illustrative and are not intended to limit the scope of this application.
[0031] This application provides a relay-based combined signal device (hereinafter referred to as a combined signal device), which will be described in detail below with reference to the accompanying drawings. It should be noted that the "connection" between the components in the combined signal device of this application can be a physical connection or a communication connection.
[0032] like Figure 1The diagram shown is a logic block diagram of a relay-based combined signal device provided in an embodiment of this application. The combined signal device includes a signal body 110, relays 120, and a signal light 130. The phase output terminal of the signal body 110 is connected to the input terminal of the signal light 130 via one or more relays 120. This allows for the control of different channels of the relays to close or open according to different control requirements, thereby controlling the on / off state of the corresponding signal light. This enables the implementation of special control modes based on conventional signal control.
[0033] The following section details each component and the connections between them.
[0034] The signal controller body 110 is provided with multiple phase output terminals for outputting corresponding control phases based on the signal controller's built-in control logic. These control phases are used to control the on / off state of corresponding light colors in the signal lights. The built-in control logic of the signal controller is prior art and is not an improvement or protected by this application. In this embodiment, the multiple phase output terminals can be standard phase output terminals of the signal controller, such as phases 1 to 15, or phase output terminals used for extension or special purposes, such as phase 16 and subsequent phases.
[0035] The relay 120 includes a coil side and a contact side. One end of the coil side is connected to an arbitrary phase output terminal, and the other end of the coil side is connected to the neutral line. The contact side includes static contacts and dynamic contacts. The static contacts on the contact side are connected to the phase output terminal with control. When the coil side is energized, it generates an electromagnetic force that drives the dynamic contacts on the contact side to operate and control the switching of the circuit.
[0036] The signal light 130 is connected to the dynamic contact on the contact side of the relay 120. It is used to connect different phase output terminals of the signal machine body 110 to the signal light based on the action of the dynamic contact, thereby realizing the control of the signal light display based on the built-in control logic of the signal machine body 110.
[0037] In this embodiment, the relay 120 and the signal body 110 can be connected by a wire to ensure the connection is secure and the electrical performance is good.
[0038] In this embodiment, the signal body 110 and the relay 120 are housed inside the signal housing to ensure stable operation in outdoor environments.
[0039] See next. Figure 2 The example circuit connection structure is shown. The control requirements of this example are: in an intersection, the right turn light in a certain direction alternates between red, yellow and green lights based on control logic during morning and evening rush hours, and during off-peak hours, the right turn light in that direction continuously outputs a flashing yellow light (i.e., a flashing yellow light).
[0040] The circuit schematic for this scenario is as follows: Figure 2 Specifically: One end of the coil side of relay 120 is connected to the green light control line of the first phase output terminal, and the other end of the coil side of relay 120 is connected to the neutral line. The first static contact a1 of the relay 120 contact side is connected to the red light control line of the second phase, and the second static contact a2 is left floating. The first static contact a1 and the second static contact a2 are switched through the first dynamic contact A. The third static contact b1 of the relay 120 contact side is connected to the yellow light control line of the second phase, and the fourth static contact b2 is connected to the yellow light control line of the third phase. The third static contact b1 and the fourth static contact b2 are switched through the second dynamic contact B. The fifth static contact c1 of the relay 120 contact side is connected to the green light control line of the second phase, and the sixth static contact c2 is left floating. The fifth static contact c1 and the sixth static contact c2 are switched through the third dynamic contact C. In this example, the first dynamic contact A on the contact side of relay 120 is connected to the live wire corresponding to the red light in the signal light, the second dynamic contact B is connected to the live wire corresponding to the yellow light in the signal light, and the third dynamic contact C is connected to the live wire corresponding to the green light in the signal light. Correspondingly, the neutral wires of the red, yellow, and green lights are connected to the neutral wire. In this example, the static contacts on the left side of relay 120 (i.e., the first static contact a1, the third static contact b1, and the fifth static contact c1) are normally open contacts, which conduct when energized and open when de-energized. The static contacts on the right side of the relay (i.e., the second static contact a2, the fourth static contact b2, and the sixth static contact c2) are normally closed contacts, with the opposite state to the normally open contacts: open when energized and conducting when de-energized.
[0041] It is understood that, in this embodiment, the first phase mentioned above is... Figure 2 The 16 phases shown, the second phase mentioned above is Figure 2 Of the 17 phases shown, the third phase mentioned above is... Figure 2 The 18 phases shown. It should be understood that, Figure 2 The circuit shown connects the relay 120 starting from the 16th phase used for extension in the signal machine, without changing the original connection relationship of the first 15 phases. In other embodiments, the relay 120 can also be connected starting from any other phase, and this embodiment is not limited to that.
[0042] Next, we will introduce... Figure 2 The circuit shown illustrates its operating principle.
[0043] In this embodiment, during morning and evening rush hours, the 16-phase output green light is activated, meaning the 16-phase green light control line is on. At this time, the coil side of relay 120 is energized, and the three sets of normally open contacts of the relay are on (i.e., the first dynamic contact A is on the first static contact a1, the second dynamic contact B is on the third static contact b1, and the third dynamic contact C is on the fifth static contact c1). At this time, the 17-phase red light control line, the 17-phase yellow light control line, and the 17-phase green light control line are all connected. The red, yellow, and green lights of the traffic lights can be controlled to alternate through the 17-phase control, thereby realizing the alternating operation of red, yellow, and green lights based on control logic during morning and evening rush hours. During off-peak hours, the 16-phase output is not green (e.g., red or yellow), meaning the 16-phase green light control line is de-energized. At this time, the coil side of relay 120 is not conductive, but its three normally closed contacts are conductive (i.e., the first dynamic contact A is conductive with the second static contact a2, the second dynamic contact B is conductive with the fourth static contact b2, and the third dynamic contact C is conductive with the sixth static contact c2). Only the 18-phase yellow light is connected, and the 18-phase output controls the yellow light to operate in a flashing yellow mode, thus achieving continuous flashing yellow output in this direction during off-peak hours.
[0044] See next. Figure 3 Another specific circuit connection structure is shown, where the control requirement is as follows: In an intersection, the right-turn light for a certain direction is red during a specific traffic phase and flashing yellow during other phases. The yellow light remains on for 4 seconds before switching to red. It should be understood that since there is no control over the green light in this scenario, the connection for the green light will not be described below.
[0045] The circuit schematic for this scenario is as follows: Figure 3 As shown, specifically: one end of the coil side of relay 120 is connected to the green light control line of the fourth phase output terminal, and the other end of the coil side of relay 120 is connected to the neutral line. The seventh static contact d1 on the contact side of relay 120 is connected to the yellow light control line of the fifth phase, and the eighth static contact d2 is connected to the yellow light control line of the fourth phase. The seventh static contact d1 and the eighth static contact d2 are switched through the fourth dynamic contact D. In this example, the fourth dynamic contact D on the contact side of relay 120 is connected to the live wire of the yellow light in the signal light, and the live wire of the red light in the signal light is connected to the red light control line of the fourth phase. The neutral connection terminals of the red and yellow lights of the signal light are connected to the neutral line. In this example, the static contact on the left side of relay 120 (i.e., the seventh static contact d1) is a normally open contact, which is conductive in the energized state and disconnected in the de-energized state. The static contact on the right side of the relay (i.e., the eighth static contact d2) is a normally closed contact, which is the opposite of the normally open contact. That is, it is open when energized and closed when de-energized.
[0046] It is understood that the fourth phase mentioned above in this embodiment is Figure 3 Of the 17 phases shown, the fifth phase mentioned above is... Figure 3 The 18 phases shown. It should be understood that, Figure 3 The circuit shown connects the relay 120 starting from the 17th phase used for extension in the signal, without changing the original connection relationship of the first 16 phases. In other embodiments, the relay 120 can also be connected starting from any other phase, and this embodiment is not limited to that.
[0047] Next, we will introduce... Figure 3 The circuit shown illustrates its operating principle.
[0048] In this embodiment, the 17-phase green light control line controls the on / off state of relay 120. When the 17-phase green light is on, the coil side of relay 120 is on, and the normally open contact of the relay is on (i.e., the fourth dynamic contact D and the seventh static contact d1 are on). At this time, the 18-phase yellow light control line is connected, and the yellow light can be controlled to operate in a flashing yellow mode through the 18-phase line, thereby fulfilling the requirement of outputting a flashing yellow light. When the green light control line of phase 17 is disconnected (i.e., the green light control line of phase 17 is de-energized), the coil side of relay 120 is not conductive, and its normally closed contact is conductive (i.e., the fourth dynamic contact D and the eighth static contact d2 are conductive). At this time, the yellow light control line of phase 17 is connected. The yellow light control line and the red light control line of phase 17 control the traffic light to display as red during a specific stage. The yellow light of phase 17 is set to remain on for 4 seconds before switching to green light, thus achieving a red light display during a certain traffic stage (when the green light control line of phase 17 is not conductive) and a flashing yellow light display during other stages (when the green light control line of phase 17 is conductive). The yellow light remains on for 4 seconds before switching to red light (when the green light control line of phase 17 is not conductive). In this embodiment, the duration of the red light of phase 17 can also be set, such as 2 seconds, 3 seconds, 10 seconds, etc.
[0049] It should be understood that the above Figure 2 and Figure 3 These are all exemplary descriptions of specific scenarios. In other embodiments, different signals can be connected by connecting relays to other phase output terminals of the signal machine to achieve different combinations of signal light on / off control.
[0050] Based on the combined signal device provided in this application, by connecting a relay to the output channel of the signal and then connecting the output phase of the signal to different connections through the relay, different combinations of signal lights can be output without adjusting the control logic, thereby meeting complex control requirements.

Those skilled in the art will understand that this application is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of this application.
