The application provides an electronic stop board aims at setting up stand-by power supply and the corresponding switching module of configuration through for centralized control ware, and the switching module is used for switching the power supply line of centralized control ware to stand-by power supply from mains supply when the outage as required to this avoids electronic stop board to fall the electricity and influences the passenger experience of taking a bus. And the centralized controller returns state information to the background in real time, and the state information may include current commercial power outage state information. Therefore, the operation and maintenance personnel can timely know that the current equipment is in the mains supply power-off state, and the operation and maintenance personnel can conveniently operate and maintain the electronic stop board according to the exact problem. Compared with the traditional electronic stop board, the standby power supply is not arranged, so that the electronic stop board is disconnected after the mains supply is powered off, and all the functional modules cannot be used. And one end of the background operation and maintenance personnel cannot receive the state information fed back by the electronic stop board in real time, so that the fault of the current electronic stop board cannot be accurately diagnosed, and better operation and maintenance cannot be achieved. Therefore, the electronic stop board provided by the embodiment of the application is provided to solve the technical problem that the existing electronic stop board cannot feed back the state information of the equipment in real time due to equipment outage.

Example (b):

fig. 1 is a schematic structural view of an electronic stop board provided in an embodiment of the present application, and referring to fig. 1, the electronic stop board specifically includes a stop board main body, and the stop board main body is as shown in fig. 2, and the stop board main body is provided with a mains power supply 110, a standby power supply 120, a centralized controller 130, and a router 140; the centralized controller 130 is electrically connected with the router 140, and uploads state information to a background in real time through signal connection with the router 140; the centralized controller 130 is connected to the commercial power source 110 through a first power supply line, and is connected to the standby power source 120 through a second power supply line, the commercial power source 110 is used for accessing commercial power and supplying power to the centralized controller 130 and the router 140 through the first power supply line, and the standby power source 120 supplies power to the centralized controller 130 and the router 140 through the second power supply line; the centralized controller 130 includes a switching module 131, where the switching module 131 is configured to selectively turn on the first power supply line or the second power supply line.

By providing the backup power source 120 and the switching module 131, the backup power source 120 and the commercial power source 110 alternately supply power to the modules of the electronic station board, and the switching module 131 is used for selectively switching the two power sources. In this embodiment, the centralized controller 130 is respectively connected to the commercial power source 110 and the standby power source 120 through a first power supply line and a second power supply line, and selects any power source to obtain power through the switching module 131, so as to supply power to the centralized controller 130 and the router 140 connected to the centralized controller 130. In practical applications, each functional module (LCD player host, temperature control system, LED display screen, lighting system, etc.) also obtains electric energy through the centralized controller 130. Typically, the centralized controller 130 has access to a first power supply line, and the power supply 110 supplies power to the centralized controller 130. When the utility power supply 110 is powered off, the switching module 131 switches the power supply of the centralized controller 130, and at this time, the centralized controller 130 is connected to a second power supply line, and the standby power supply 120 supplies power to the centralized controller 130. Therefore, the electronic stop board can still normally operate under the condition that the commercial power is cut off, and the state information of the electronic stop board can still be sent to the background in real time through the router 140. Afterwards, when the commercial power source 110 recovers to supply power, the switching module 131 switches the power supply of the centralized controller 130 again, and the centralized controller 130 is connected to the first power supply line, so that the commercial power source 110 supplies power to the centralized controller 130. In practical applications, referring to fig. 3, in order to simplify the wiring for the convenience of module arrangement, the router 140 is generally integrated into the centralized controller 130, so as to improve the integration degree of the electronic stop board and optimize the internal module arrangement of the electronic stop board.

In one embodiment, when the integrated controller 130 uses the backup power source 120 to supply power, in order to avoid excessive power consumption of the electronic stop board, the normal operation time of the electronic stop board is extended (before the power supply 110 is restored), and then the integrated controller 130 powers down part of the functional modules (such as the temperature control system, the heat dissipation system, etc.), and only maintains the normal power supply of the necessary functional modules. For example, when the commercial power is cut off, the centralized controller 130 takes power from the standby power supply 120, and only provides electric energy for the router 140 and the LED display screen, so that the operation of the LED display screen is maintained, the electronic stop board can be ensured to display stop reporting information in real time, and the passenger riding experience is prevented from being influenced. The router 140 is maintained to operate, so that the background can conveniently acquire the state information of the electronic stop board in real time, and the operation and maintenance are facilitated.

Specifically, the switching module 131 includes a voltage detection sub-module, and the voltage detection sub-module is configured to detect the output voltage of the first power supply line and the output voltage of the second power supply line in real time; correspondingly, the switching module 131 is configured to selectively turn on the first power supply line or the second power supply line according to the output voltage of the first power supply line and the output voltage of the second power supply line. It will be appreciated that the centralized controller 130 is typically powered by the mains supply 110 by default. And the voltage detection submodule detects the output voltages of the first power supply line and the second power supply line in real time so as to judge whether the current commercial power supply 110 is powered down. When the utility power supply 110 is powered off, and it is detected that the output voltage of the first power supply line is 0, the switching module 131 switches the centralized controller 130 to access the second power supply line according to the detection result. Meanwhile, the centralized controller 130 stores the current operation data and feeds the power-down condition of the mains supply back to the background. When detecting that the output voltage of the first power supply line returns to normal (i.e. 220V), the switching module 131 switches the centralized controller 130 to access the first power supply line according to the detection result. In an embodiment, the switching module 131 may further select one power supply line to get power according to the output voltages of the first power supply line and the second power supply line and the stability of the output voltages. Rather than by default selecting the mains supply 110 as the power supply.

In one embodiment, the utility power source 110 is further electrically connected to the backup power source 120 for charging the backup power source 120. That is, the commercial power supply 110 of the embodiment of the present application supplies power to the centralized controller 130 on one hand and charges the standby power supply 120 on the other hand when supplying power normally. The backup power source 120 is a ups (uninterruptible power supply), i.e., an uninterruptible power supply, which can provide a stable and uninterrupted power supply for the electronic bus stop board. When the mains supply input is normal, the UPS stabilizes the mains supply and charges the built-in power supply; when the mains supply is powered off, the UPS immediately supplies 220V alternating current to the electronic stop board by converting the direct current electric energy of the built-in power supply through the inverter, so that the electronic stop board keeps normal work and protects load software and hardware from being damaged. Furthermore, the UPS can provide protection for over-voltage or under-voltage. Further, the backup power source 120 includes a farad capacitor for storing electric energy. The farad capacitor stores energy through polarized electrolyte, but no chemical reaction occurs, and the energy storage process is reversible. The electronic bus stop board can be repeatedly charged and discharged for tens of thousands of times, has the maximum capacity of thousands of farads, and is suitable for the electronic bus stop board in the embodiment of the application.

Referring to fig. 4, in one embodiment, the electronic station board further includes a solar photovoltaic panel set 150, and the solar photovoltaic panel set 150 is electrically connected to the standby power supply 120, and is used for solar power generation and charging of the standby power supply 120. The electronic stop board is charged through the solar photovoltaic panel group 150, so that the energy-saving and environment-friendly effects of the electronic stop board can be realized, and the power consumption cost of the electronic stop board is further reduced. Moreover, when the commercial power is continuously powered down, the situation that the standby power supply 120 is out of power can be avoided, so that the electronic stop board is disconnected, and the riding experience of passengers is influenced.

Further, in practical applications, the backup power source 120 may be charged through two channels, i.e., the solar photovoltaic panel assembly 150 and the utility power source 110, so as to further ensure that the backup power source 120 does not have a power failure. Also, the backup power source 120 maintains a float state when fully charged so that the backup power source 120 can be constantly maintained in a charge satisfaction state without being overcharged.

Referring to fig. 5, in one implementation, the centralized controller 130 further includes a voltage stabilizing module 132, and the voltage stabilizing module 132 interfaces with the switching module 131 to stabilize the input voltage of the centralized controller 130. The voltage stabilizing module 132 may stabilize the input voltage through a voltage stabilizing circuit. Thus, the voltage can be kept constant by the voltage regulator module 132 no matter the input voltage of the centralized controller 130 fluctuates (e.g., switching between the main power supply 110 and the standby power supply 120) or the load changes (power off of each functional module).

Further, the integrated controller 130 further includes a voltage transformation module 133, where the voltage transformation module 133 is configured to convert the 220V ac voltage output by the commercial power source 110 into a dc voltage. The transforming module 133 may implement transformation through a transforming circuit. It is understood that the voltages used by the functional modules interfaced by the centralized controller 130 are different, and the voltage of the AC220V or the backup power source 120 can be converted into the voltages required by the functional modules through the voltage transformation module 133. Further, the centralized controller 130 is electrically connected to the router 140 via a DC24V power interface. It can be understood that the router 140 is powered by the DC24V voltage, and the transformer module 133 is required to convert the voltage into the DC24V by the corresponding transformer circuit and output the DC24V to the router 140 for use. Similarly, other functional modules corresponding to the electronic station board need to be adaptively converted into corresponding direct current or alternating current voltages and supplied to the corresponding functional modules for use.

In addition, the centralized controller 130 is further connected to an alarm module 134, and the alarm module 134 is configured to alarm in real time when the first power supply line is powered off. It can be understood that, for the convenience of management of operation and maintenance personnel, by setting the alarm module 134, the alarm module 134 can be realized by an indicator lamp or a loudspeaker, and when the mains supply is powered down, the current mains supply is prompted to be powered down in real time through the indicator lamp or the loudspeaker, so that the operation state of the current electronic stop board can be visually known by the operation and maintenance personnel and other relevant managers.

Furthermore, the centralized controller 130 is further connected to a video monitoring module 135, and the video monitoring module 135 is configured to monitor the connection condition of the utility power supply 110 in real time. In general, the power failure of the utility power supply 110 may be caused by a loose power interface, a broken line, a physical damage of a related device, and the like which can be determined by naked eyes, and the video monitoring module 135 performs real-time video monitoring on the electronic stop board, so that operation and maintenance personnel can better diagnose the current specific reason causing the power failure of the utility power supply. In addition, the video monitoring module 135 may actually perform video data acquisition corresponding to the whole site, so as to monitor the real-time operation condition of the site, thereby facilitating the monitoring and management of operation and maintenance personnel.

As described above, the centralized controller 130 is in signal connection with the router 140 to upload the state information to the background in real time, and the centralized controller 130 is further docked with the commercial power source 110 and the standby power source 120, and is connected to the commercial power source 110 through a first power supply line to supply power to the centralized controller 130 and the router 140, or is connected to the standby power source 120 through a second power supply line to supply power to the centralized controller 130 and the router 140. The centralized controller 130 is further provided with a switching module 131, and the power input of the centralized controller 130 is switched to a second power supply line through the switching module 131 when the commercial power is off, so that the standby power supply 120 supplies power to the centralized controller 130 and the router 140. By adopting the technical means, the real-time switching between the commercial power supply 110 and the standby power supply 120 can be realized, and the electronic stop board can transmit the state information back to the background in real time after the commercial power is cut off, so that the electronic stop board can be operated and maintained conveniently.
