[0028] The present application will be further described below with reference to the drawings and embodiments.

[0029] Figure 1 A structural block diagram of a post signal lamp system provided by an exemplary embodiment of the present application is shown. The post signal lamp system comprises a changeover switch, a leakage protector, and an inverter charging all-in-one machine. The first input end of the changeover switch is connected with a commercial power supply, and the second input end of the changeover switch is connected with a third power supply. The input end of the leakage protector is connected with the output end of the changeover switch. The AC input end of the inverter charging all-in-one machine is connected with the first output end of the leakage protector, the first AC output end of the inverter charging all-in-one machine is connected with an auxiliary function component, the second AC output end of the inverter charging all-in-one machine is connected with a signal machine, and the DC input-output bidirectional port of the inverter charging all-in-one machine is connected with a battery pack. The signal machine is connected with a signal lamp group, and the signal machine is further connected with a mobile terminal and a server through a communication module.

[0030] In the embodiments of the present application, the design of the kiosk signal lamp system aims to provide a stable, reliable and intelligent traffic management solution. The function of the change-over switch is to ensure that the system can obtain power from the mains power supply or the third standby power supply, so as to maintain the normal operation of the system when the main power supply fails. The leakage protector is connected after the change-over switch, which is responsible for monitoring the current flow in the circuit, and will immediately cut off the power supply to protect personnel and equipment safety once abnormal leakage phenomenon (such as equipment shell electrification) is detected. The inverter charging all-in-one machine, as one of the core components of the system, receives the alternating current processed by the leakage protector through its alternating current input end, not only can power the auxiliary functional components (such as lighting lamp group, fan group, etc.), but also can power the signal machine through its second alternating current output end, and through the direct current input-output bidirectional port connected with the battery pack, realize the charge-discharge management of the battery and the conversion of the stored energy into usable alternating current. In addition, the signal machine not only controls the operation of the signal lamp group, but also realizes data exchange with mobile terminals and servers through the communication module, so that the manager can remotely monitor and adjust the state of the signal lamp, that is, the kiosk commander can remotely monitor and adjust the state of the signal lamp through the mobile terminal (mobile phone, tablet, etc.), and the background traffic management platform can remotely monitor and adjust the state of the signal lamp by accessing the server, which improves the traffic management and maintenance efficiency. Such architecture ensures that even in the case of power failure or other emergency situations, the traffic signal lamp can continue to operate, thereby maintaining road traffic order and reducing the occurrence of traffic accidents.

[0031] In one example, the third power supply is provided by a standby generator; the change-over switch is a NA00324-WATS automatic change-over switch; the leakage protector is a LS8 leakage protection circuit breaker; the inverter charging all-in-one machine is an EK802 manufactured by Jiangsu Aikesai Electrical Manufacturing Co., Ltd.; and the communication module is a 4G LTE module.

[0032] Further, the kiosk signal lamp system further comprises an alternating current contactor and a solar panel group, the main contact input end of the alternating current contactor is connected with the second output end of the leakage protector; the solar panel group is connected with the auxiliary contact NC input end of the alternating current contactor, and the auxiliary contact NC output end of the alternating current contactor is connected to the battery pack through a solar charger.

[0033] In some embodiments, the solar panel group is installed on the top of the kiosk signal lamp for charging the battery pack when the regular alternating current power supply is open, and the model of the solar panel group is a Hi-MO 5 high-efficiency monocrystalline PERC component.

[0034] In the embodiments of the present application, the design of adding an AC contactor and a solar panel group in the post signal lamp system is to realize a more intelligent and energy-saving power management mode. Specifically, the AC contactor serves as a switching element in the circuit, and its main contact input end is connected with the second output end of the leakage protector, for detecting the presence or absence of commercial power. When the commercial power is normally supplied, the main contact of the AC contactor is closed, and the auxiliary contact NC (normally closed) remains in an open state, which means that the solar panel group will not charge the battery group at this time, avoiding unnecessary energy conversion loss in the case of available commercial power. However, as soon as the commercial power is interrupted or fails, the main contact of the AC contactor will automatically open after losing AC input, and at this time the auxiliary contact NC of the AC contactor is immediately turned on. In this way, the solar panel group can directly charge the battery group through the solar charger, ensuring that even in the absence of commercial power, the system can still rely on the pre-stored energy to maintain the operation of basic functions, such as the continuous operation of traffic signal lights. This design not only improves the self-sufficiency of the system, enhances the stability and reliability in the face of unexpected situations, but also embodies the concept of green environmental protection, reduces the dependence on external power supply by using renewable energy, reduces operating costs and carbon emissions. In addition, such a configuration also allows the system to flexibly adjust the energy supply strategy according to the actual environmental conditions, for example, it can fully utilize solar energy resources to supplement or replace traditional commercial power supply during the day, and switch back to commercial power supply mode at night or in insufficient light, thereby realizing optimal management of energy use.

[0035] In some embodiments, the auxiliary function assembly includes a set of lighting lamps installed on the post signal lamp for night directing illumination, a set of fans installed on the post signal lamp for cooling the director when the weather is hot, and an LED display screen installed on the post signal lamp for prompting vehicles when traffic control is needed.

[0036] Next, the working principle of a post signal lamp system according to an embodiment of the present application is described.

[0037] The platform signal lamp system selects mains or backup power supply through a change-over switch to ensure normal operation when the main power fails; the leakage protector monitoring circuit ensures safety and prevents leakage accidents. The inverter charging integrated machine, as a core component, not only supplies power to auxiliary equipment and signal machines, but also manages the charging and discharging of the storage battery, and can convert stored DC power into AC power to supply the system when needed. The signal machine controls the signal lamp group and connects with mobile terminals and servers through a communication module to support remote monitoring and adjustment. In addition, the system integrates AC contactors and solar panels to automatically switch to solar charging mode when the mains are interrupted, enhancing the self-sufficiency and environmental performance of the system. This design ensures that the traffic signal lamp can work continuously under various conditions, maintains traffic order, and optimizes energy use management.

For example, "connection" can be fixed connection, detachable connection or integral connection; "connection" can be direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the embodiments disclosed in the present application can be understood according to specific circumstances.

[0039] The above is only the preferred embodiment of the present application, and it should be pointed out that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the protection scope of the present application.
