[0037] In order to improve the service life of components in a bus stop, an embodiment of the present application provides a bus stop system. The solution of the present application is described below with reference to the accompanying drawings:

[0038] Figure 1 A structural schematic diagram of a bus stop system provided in an embodiment of the present application, the bus stop system 100 may include: a main board 101, a temperature control board 102, a temperature sensor 103, a light sensor 104 and a display screen 105, wherein the light sensor 104 is connected to the main board 101, the temperature sensor 103 is connected to the temperature control board 102, and the temperature control board 102 is also connected to the main board 101; the temperature control board 102 is used to control the temperature inside the bus stop system based on the temperature sensor 103; the main board 101 is used to control the brightness of the display screen 105 based on the light sensor 104 and / or the temperature sensor 103.

[0039] By applying the embodiments of the present application, the ambient temperature is monitored by a temperature sensor, the ambient light condition is monitored by a light sensor, and then the operating temperature of the bus stop system is adjusted based on the ambient temperature by a temperature control board, thereby avoiding failures of components in the bus stop system due to overcooling or overheating, protecting each component, and extending the service life of each component. In addition, the brightness of the display screen is adjusted based on the ambient light condition by the main board, thereby avoiding continuous high-brightness display of the display screen and extending the service life of the display screen.

[0040] The above bus stop system is described below by way of example:

[0041] The above-mentioned bus stop system may include a display screen, which can display the arrival information and driving information of the bus, and can also display other multimedia information such as commercial advertisements and city promotional videos, which can be set according to actual needs. The display screen can be an LCD (Liquid Crystal Display) display screen or an LED (light-emitting diode) display screen, and the specific type of the display screen can also be set according to actual needs.

[0042] The above-mentioned bus station system may also include an integrated circuit breaker module, which can control the power supply of various components in the bus station and the closing and opening of the bus station. Specifically, the integrated circuit breaker module can protect the bus station, including leakage protection, whole machine temperature protection, overvoltage and undervoltage protection, malicious load protection, arc protection, voltage mutation and current overcurrent mutation protection, etc. In the event of an abnormality at the bus station, the power supply can be disconnected in time to ensure that the circuit is not damaged.

[0043] The above-mentioned bus stop system includes various sensors, such as a temperature sensor, a humidity sensor and a light sensor.

[0044] The temperature sensor may be a thermometer. As a possible implementation, it may be a plurality of thermometers installed inside the bus stop. The installation position of the temperature sensor may be set according to actual needs. For example, the bus stop system is usually formed by a protective cover to form a bus stop body that can be installed on the ground. The protective cover is usually in the shape of a rectangular parallelepiped. Therefore, four thermometers may be evenly arranged at the top, bottom, left, and right of the bus stop. The humidity sensor may be a hygrometer, and its installation method may be the same as that of a thermometer, which will not be described in detail here.

[0045] The above-mentioned light sensor can be a photosensitive element, which can be used to collect white light, infrared light information, etc. There are multiple light sensors, which can be installed outside the bus stop, such as above or below the display screen, or on the back of the bus stop. As a possible implementation, the light sensors can be evenly installed around the bus stop, or only installed on the side of the display screen, which is not specifically limited in this application.

[0046] The main board in the bus stop system is connected to the above-mentioned light sensor and adjusts the brightness of the display screen according to the ambient light data collected by the light sensor. Specifically, the main board can set PWM (Pulse width modulation) based on the light parameters sent by the light sensor; the set PWM is output to the backlight constant current board to drive the backlight constant current board to control the brightness of the display screen.

[0047] As a possible implementation, the lighting parameters sent by the above-mentioned light sensor may include ambient light value and infrared light value. The specific calculation process may be k×(ambient light value-infrared light value), where k is a preset coefficient, which may be 1.5, 2, etc., and can be set according to actual needs. The value obtained by the above formula is the PWM value that needs to be set.

[0048] In a possible embodiment, when the light sensor is installed inside a bus stop, the light it receives will pass through the protective cover, resulting in low accuracy of the obtained light data. Therefore, a basic gain of 500 and a dark light filter gain of 1600 can be added to the parameters collected by the light sensor as ambient light values ​​involved in the calculation. The above two gains are based on pre-experimental settings.

[0049] In a possible embodiment, the mainboard can obtain the ambient light data collected by the light sensor at a preset time interval. The time interval can be determined based on the historical flow of people. For example, it can be determined that the time interval is shorter during peak hours in the morning and evening when the flow of people is large, and the time interval is longer during peak hours when the flow of people is small, thereby reducing the heat and power consumption caused by frequent brightness adjustment. In a possible embodiment, the above historical flow of people can be collected by a camera in the bus stop system.

[0050] The above calculation process will exclude sensor data with large errors caused by direct light from vehicles and street lamps. Specifically, after obtaining the data sent by the light sensor, the mainboard can filter the light data whose error with the light data collected by other light sensors is greater than a preset error threshold to obtain the light parameters. The error threshold can be set arbitrarily and this application does not make specific restrictions on this.

[0051] In a possible embodiment, the above-mentioned bus stop system may also include a SIM (Subscriber Identity Module) card, which includes a communication module. The bus stop system can exchange data with the cloud platform through the communication module of the SIM card. The communication module may be a 4G communication module, a 5G communication module or other feasible communication modules. The cloud platform is built based on a background server.

[0052] The cloud platform can send a control signal to the mainboard through the SIM card. The control signal can control whether the bus station system turns on automatic brightness adjustment. When the cloud platform turns off automatic brightness adjustment, the mainboard sets a constant PWM output to the backlight constant current board, and the backlight constant current board will send a fixed brightness to the screen. When the cloud platform turns on automatic brightness adjustment, the mainboard executes the above automatic brightness adjustment logic.

[0053] The bus stop system also includes a temperature control board, which is connected to the temperature sensor and can adjust the temperature inside the bus stop according to the temperature sensor. As a possible implementation, the temperature control board can control the operation of the temperature control module according to the temperature sensor, thereby adjusting the temperature inside the bus stop.

[0054] The temperature control module may include fans and heaters. For example, 6 fans and 4 heaters may be included. These fans and heaters may be set at any position inside the bus stop, or may be evenly set inside the bus stop. For example, a heater may be set at each of the four positions inside the bus stop, and 2 fans may be set at the upper and lower sides of the bus stop, and 1 fan may be set at each of the left and right sides of the bus stop. The temperature control board may control the fans and heaters through PWM signals.

[0055] In a possible embodiment, the temperature control board can also control the backlight constant current board based on the temperature sensor, thereby controlling the brightness of the display screen. Specifically, the temperature control board can send the ambient temperature information collected by the temperature sensor to the main board, and the main board adjusts the brightness of the display screen based on the temperature information.

[0056] As a possible implementation, Figure 2 As shown, the safety temperature, warning temperature and protection temperature can be set in advance in the temperature control board, wherein the above-mentioned safety temperature refers to the lower limit of the temperature for normal operation of the bus stop, the warning temperature refers to the upper limit of the temperature for daily operation of the bus stop, and the protection temperature refers to the temperature at which the bus stop may overheat and cause abnormal components, the above-mentioned protection temperature>warning temperature>safety temperature, the specific values ​​of the above-mentioned three temperatures can be set according to actual needs, and this application does not make specific limitations on this, and the above-mentioned three temperatures can be stored in the temperature control board and the main board.

[0057] like Figure 2 As shown, when the current ambient temperature is lower than the safe temperature, it means that the current ambient temperature is too low, so the heater can be controlled to start working to increase the temperature inside the bus stop.

[0058] When the current ambient temperature is higher than the safety temperature and lower than the warning temperature, it means that the current ambient temperature is a temperature at which the bus stop can operate normally. Therefore, the fan, heater and backlight constant current board can be in normal working mode. The normal working mode can be set according to actual needs. For example, the fan and heater can operate in a preset low-frequency mode. The low-frequency mode can be PWM of 3%-5%. The normal working mode of the backlight constant current board means that the main board does not need to adjust the backlight constant current board based on the temperature, and the PWM output to the backlight constant current board can be adjusted according to the above-mentioned automatic lighting adjustment process.

[0059] When the current ambient temperature is higher than the warning temperature but lower than the protection temperature, it means that the current ambient temperature is too high. Therefore, the fan can be controlled to work at its maximum power, and the backlight constant current board can be controlled to have the lowest brightness. Specifically, the temperature control board sends the current ambient temperature information to the main board. When the main board determines that the ambient temperature is higher than the warning temperature, the PWM of the output backlight constant current board is reduced to the preset minimum value.

[0060] When the current ambient temperature is higher than the protection temperature, it means that the current ambient temperature will cause abnormal components. Therefore, the integrated circuit breaker module can be controlled to open to achieve power failure protection of the bus station. Specifically, the current ambient temperature can be output to the main board, and the main board controls the integrated circuit breaker module to open.

[0061] Since some bus stops do not need to display information at night, in a possible embodiment, the temperature control board can also be provided with the temperature control module control logic for the idle working state and the temperature control module control logic for the non-idle working state. The idle working state refers to the display screen being turned off or the bus stop system being powered off. The temperature control board can determine whether the bus stop is in the idle working state through the internal relay or the display screen playback board interface. Specifically, when the display screen is turned off or the bus stop system is powered off, the internal relay is at a low level. Therefore, the temperature control board can determine that the current state is the idle working state when the internal relay is at a low level. As another possible implementation, when the playback board interface is OFF, it is determined that the current state is the idle working state.

[0062] The control logic of the temperature control module in the idle working state can be to reduce the PWM output and the fan speed, and control the fan to run at low power. The low power can be set according to the fan parameters. The non-idle working state can be to increase the PWM output and the fan speed, or Figure 2 The temperature control logic shown.

[0063] In a possible embodiment, the cloud platform can exchange data with the mainboard through the SIM card to set the temperature control board to output the PWM of the fan under the default and idle working conditions at different temperatures, so as to facilitate the response to different weather conditions.

[0064] like Figure 3 As shown, Figure 3 This is a flow chart of the temperature control board control logic in this application. Specifically, the temperature control board determines whether it is in an idle working state based on the internal relay or the playback board interface. If it is in an idle working state, the idle working state control logic is executed, specifically, the PWM output and the fan speed are reduced. If it is in a non-idle working state, the non-idle working state processing logic is executed, specifically, the PWM output and the fan speed are increased. When the entire bus station is shut down, the control ends.

[0065] In a possible embodiment, when the humidity sensor detects water immersion, an alarm signal may be sent to the main board, and the main board may send the corresponding alarm information to the cloud platform. In a possible embodiment, the bus stop system may also include a smoke sensor module, which is used to send an alarm signal to the main board when smoke is detected, and the main board may send the corresponding alarm information to the cloud platform.

[0066] In a possible embodiment, the mainboard can communicate with the cloud platform through a SIM card to obtain the data to be displayed issued by the preset cloud platform; send the data to be displayed to the mainboard; and the mainboard is used to drive the display screen to display the data to be displayed.

[0067] Specifically, it is possible to communicate with bus companies to obtain information such as the routes, locations, license plate numbers, etc. of each bus, and send it to each bus stop. The bus stop can parse the arrival information and bus route information of the buses stopped at its station based on the travel information of each bus according to its station.

[0068] The cloud platform can also send playlists and playlist materials to each bus station. The playlist is used to specify when to play which playlist materials, and the playlist materials are customized advertisements, news, messages, knowledge, etc. The cloud platform can send materials to bus stations according to customer needs to achieve the purpose of real-time material updates.

[0069] In a possible embodiment, in order to ensure the security of data interaction, the bus stop can perform digital signature authentication based on the bus stop number contained in the information sent by the cloud platform, and subsequent data interaction can only be carried out after the authentication is passed.

[0070] In a possible embodiment, the bus stop system may further include a storage unit. The bus stop system may save all received data to the storage unit. The storage unit may be an emmc (Embedded Multi Media Card, embedded memory standard specification) storage.

[0071] For example, Figure 4 An LCD screen display is shown, wherein the upper left half of the LCD screen (hereinafter referred to as area 1) is a 4:3 DTMB (Digital Terrestrial Multimedia Broadcast) real-time signal, the lower left half (hereinafter referred to as area 2) is real-time arrival information, and the right side (hereinafter referred to as area 3) is a 9:16 vertical screen.

[0072] Among them, the screen in area 1 is a DTMB video played by tuning, channel filtering, channel equalization, multi-channel improvement, demodulation, stereo decoding, noise suppression and weak signal processing of the AM / FM signal sent by the cloud platform received by the bus station through a radio receiver to obtain the multimedia broadcast signal. If no signal is received or the signal analysis fails due to a fault, the local video is played, which refers to the above-mentioned playlist material video.

[0073] Area 2 displays the arrival information of buses at the station. Specifically, it can display the arrival information of 3 lines at a time, and supports scrolling of multiple lines with a page turning interval of 15 seconds. Area 3 plays the corresponding materials according to the playlist issued by the customer, which can promote multiple businesses, reduce costs and increase profits.

[0074] In a possible embodiment, the bus stop system may further include an adapter board and a logic board. The adapter board may be a 4K or 2K adapter board, such as VBYONE (a digital interface standard developed for image transmission). As a possible implementation, the 4K adapter board may convert the 4K60HZ data sent by the cloud platform into 4K120HZ data and send it to the logic board. The logic board may display the data on the display screen according to the preset display position.

[0075] In a possible embodiment, the SIM card is also used to obtain configuration information issued by the preset cloud platform, and send the configuration information to the temperature control board and the main board; the configuration information includes a temperature threshold and a screen switching time; the temperature control board is used to lower the temperature of the bus stop system when the temperature inside the bus stop system exceeds the temperature threshold; the main board is used to control the switching of the display screen according to the screen switching time.

[0076] like Figure 5 As shown, Figure 5 An architecture diagram of a bus stop system provided in an embodiment of the present application, the bus stop system may include a temperature sensor, a humidity sensor, a fan, a heater, a temperature control board, a main board, a light sensor, a backlight constant current board, an integrated circuit breaker, a lightning protection device, a camera, a 4K adapter board, a logic board, and an LCD display screen, wherein the temperature control board is connected to the temperature sensor and the humidity sensor, and can control the fan and the heater according to the ambient temperature and humidity, thereby adjusting the temperature inside the bus stop system, and the temperature control board is also connected to the main board, and can send the ambient temperature and humidity data to the main board. The main board is connected to the light sensor and the camera, and can adjust the backlight constant current board and then adjust the brightness of the LCD display screen according to the ambient light information transmitted by the light sensor and the camera. The main board is also connected to the cloud platform through the SIM card 5G module, receives various data to be displayed issued by the cloud platform, and displays the data to be displayed to the preset display position of the LCD screen through the 4K adapter board and the logic board. The integrated circuit breaker is used to provide leakage protection, timed opening and closing, etc. for the bus stop system.

[0077] By applying the embodiments of the present application, the use of the LCD screen of the bus stop can be adjusted according to the environment to extend the service life, and the ambient temperature inside the bus stop system can be controlled according to the external environment to protect the chip boards and functional modules inside the machine. In addition, the present application uses photosensitive components and cameras as channels for obtaining external environmental information, and also uses temperature control sensors, backlight constant current boards and air switches to protect the inside of the equipment, reduce the impact of complex environments on the operation of the bus stop system, extend the service life of the equipment, and extend the manual maintenance cycle. In addition, the present application uses light sensing adjustment technology and temperature control adjustment technology, which can automatically adjust the screen brightness and the internal temperature of the whole device according to the real-time lighting conditions and the external environment. The bus stop system performs daily operations through the cloud platform to obtain equipment information and various environmental parameters. There is no need for dedicated management operations. The outdoor screen playback situation and the issuance of bus information can be specially set. When the equipment fails, it will be reported to the platform in time so that maintenance personnel can understand the situation in time.

[0078] Among them, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved in this application are in compliance with the relevant laws and regulations and do not violate public order and good morals.
