Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the present application.

[0030] With reference to the drawings accompanying the specification, Figures 1-5 The present application provides a kind of based on GPRS's bus terminal, including terminal body 1, display screen 2 and camera 3 are installed in the front end of terminal body 1, terminal body 1 rear end is equipped with GPRS module 4, GPRS module 4 can select TP301V4, terminal body 1 is equipped with sunshade assembly 5, sunshade assembly 5 includes the sunshade cover 51 of being covered in the outside of terminal body 1, terminal body 1 rear end is processed with mounting groove 6, GPRS module 4 is inserted in mounting groove 6, mounting groove 6 top both sides are equipped with spring bolt 7, GPRS module 4 top is processed with two slots 8, spring bolt 7 is inserted with slot 8.

[0031] In actual use, the bus driver first installs the fixing mechanism 9 on the inner wall of the bus cab, then adjusts the position of the terminal body 1 to a position that does not affect driving and is convenient for observing the display screen 2, and then uses the terminal body 1. The terminal body 1 realizes data interaction connection between the terminal body 1 and various devices in the bus (such as a driving recorder, a bus host, an internal camera 3 of the bus, etc.) and a platform control terminal through TCP / IP, UDP, HTTP, MQTT, etc. in the GPRS module 4, so that the passengers at the platform can know the position of the bus in real time, and the data is displayed and processed in real time through the display screen 2, so that the bus driver can check the status of the bus at any time during driving, and can also view the status of the passengers in real time according to the picture taken by the internal camera 3 of the bus, and can also send the real-time position of the bus to the bus management bureau, so as to monitor the position of the bus in real time. The camera 3 on the terminal body 1 can take pictures of the cab in real time to ensure the safety of the bus driver. Since the terminal body 1 is located above the bus interior console, the bus driver does not need to look down to check, which reduces the risk of accidents caused by looking down, thereby improving safety. At the same time, the sunshades 51 on the outside of the terminal body 1 and the GPRS module 4 can block sunlight to avoid direct sunlight on the terminal body 1 and the GPRS module 4, which can cause high temperature, shell cracking, etc. of the two, and can also avoid sunlight from causing the display screen 2 to reflect light, thereby enabling the bus driver to accurately read the display content to further improve driving safety.

[0032] In addition, the sunshade 51 is pulled out of the terminal body 1, then the connection line between the GPRS module 4 and the terminal body 1 is disconnected, and then the pin rod in the spring latch 7 is moved out of the insertion slot 8 by pulling the two dial plates, so that the GPRS module 4 can be taken out of the installation slot 6, which is convenient for disassembling the GPRS module 4 for maintenance and replacement. When reinstalling, the GPRS module 4 is only inserted into the installation slot 6, and the pin rods in the two spring latches 7 are inserted into the insertion slots 8, so that the GPRS module 4 can be fixed. The structure is simple and the installation and disassembly are very fast.

[0033] In this embodiment, as shown in Figure 2 and Figure 4 An opening 10 is formed at the bottom of the sunshade 51, the outer walls on both sides of the terminal body 1 are processed with clamping grooves 52, the inner walls on both sides of the sunshade 51 are fixedly provided with clamping strips 53, the clamping strips 53 are inserted into the clamping grooves 52, the outer wall of the sunshade 51 is processed with a plurality of arc-shaped grooves 54, the plurality of arc-shaped grooves 54 are uniformly distributed on the surface of the sunshade 51, and the outer wall surface of the sunshade 51 is coated with light-absorbing paint. The arc-shaped grooves 54 can make the surface of the sunshade 51 uneven, so that the sunlight can be repeatedly refracted on the surface, and the light-absorbing paint can improve the light-absorbing effect of the sunshade 51, thereby further improving the light-shielding protection effect of the terminal body 1 and the GPRS module 4.

[0034] Referring to the description attached Figures 1-4 And Figure 6 , the fixing mechanism 9 includes a mounting seat 91 and an electric push rod 92, both ends of the electric push rod 92 are fixedly provided with a damping rotating shaft 93, the damping rotating shaft 93 on the telescopic end of the electric push rod 92 is arranged in the opening 10, and the two damping rotating shafts 93 are respectively detachably connected with the front end of the mounting seat 91 and the rear end of the terminal body 1. The electric push rod 92 is telescopic, which is convenient for adjusting the distance between the terminal body 1 and the bus driver, and the display angle of the terminal body 1 can be adjusted through the damping rotating shaft 93.

[0035] And, two handles 11 are fixedly arranged on the front end of the mounting seat 91, the two handles 11 are arranged above the damping rotating shaft 93, and four suction cups 94 are detachably connected with the rear end of the mounting seat 91. The four suction cups 94 are evenly distributed on the rear end of the mounting seat 91, and a rectangular embedding groove 95 is arranged at the center of the rear end of the mounting seat 91. A solar cell panel 96 is detachably connected in the rectangular embedding groove 95. The solar cell panel 96 can convert solar energy into electrical energy, so as to achieve the effects of energy saving and environmental protection.

[0036] In actual use, the bus driver holds the handle 11 and presses the plurality of suction cups 94 on the inner wall of the bus cab. The air in the suction cup 94 is squeezed out, so that a relative vacuum state is formed in the suction cup 94. The suction cup 94 is tightly pressed on the inner wall of the bus cab. When disassembly is needed, the driver presses the button on the suction cup 94 to release the air in the suction cup 94, so that the suction cup 94 can be separated, and the mounting seat 91 can be quickly taken down. The bus terminal can be maintained and repaired, and the position of the mounting seat 91 can be adjusted, so that the bus terminal is more flexible to use.

[0037] Although the utility model has been described in detail above with general description and specific embodiments, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the utility model shall fall within the scope of protection of the utility model.
