the constructor mobile phone, the facility operator mobile phone, the firewall, the wireless communication server and the monitoring system server adopted in the embodiment are all commodities which can be purchased in the market, the scheduling terminal is a special terminal special for the maintenance construction monitoring system, the main board is an ARM chip main board which can be purchased in the market and has low price, a serial data interface and a reset end, and the scheduling terminal is used as equipment connected with the railway internal network in the maintenance construction monitoring system, is designed to only contain one physical and logical memory, and is formatted when the maintenance construction monitoring system is started up every time. The memory of the dispatching terminal is ensured to be clean, and the monitoring system server downloads the linux operating system and required files, information and databases; after the downloading is finished, the monitoring system server cuts off the Ethernet connection with the monitoring system server, and also sets a corresponding Ethernet port to stop working, then starts the operating system, starts the serial port connection with the wireless communication server, and enters a working state until the monitoring system server is shut down.
Example 3
For the scheduling terminal in embodiment 1 and embodiment 2.
The embodiment is realized by modifying the wiring of the corresponding pins of the standard Ethernet port (shown in figure 8) on the dispatching terminal and adding a negative pulse monostable circuit.
Specifically, fig. 9 (a) and fig. 9 (b) respectively show an RJ-45 socket and plug wiring schematic diagram for an ethernet port of a scheduling terminal according to an embodiment of the present invention; the 1 pin of the Ethernet port RJ-45 socket of the dispatching terminal is connected with the data receiving end of the serial port of the dispatching terminal, the 2 pin and the 3 pin are connected with a ground wire, the 4 pin and the 5 pin are respectively connected with a differential line TX+ and TX-, the 6 pin is connected with the input end of a negative pulse monostable circuit, the output end of the negative pulse monostable circuit is connected with the reset end of the main board of the dispatching terminal, and the 7 pin and the 8 pin are respectively connected with the differential line RX+ and RX-; the connection of the RJ-45 plug used for the Ethernet port of the dispatching terminal is 1 pin and 2 pin, 3 pin and 6 pin, 4 pin and 5 pin are respectively connected with differential lines TX+, TX-,7 pin and 8 pin are respectively connected with differential lines RX+ and RX-; therefore, once the RJ-45 head of the embodiment of the invention is inserted into the RJ-45 socket of the dispatching terminal, the input end of the first NOT gate A1 is changed from high potential to low potential by connecting the 6 pins thereof with the ground wire through the 3 pins, the output end of the first NOT gate A1 is changed from low potential to high potential, the capacitor C is charged, high potential is generated on the pull-down resistor R3, the output end of the second NOT gate A2 is changed from high potential to low potential, the voltage is continuously increased along with the continuous charging of the capacitor C, the potential on the pull-down resistor R3 is continuously reduced, and the output end of the second NOT gate A2 is changed from low potential to high potential. The first NOT gate A1, the second NOT gate A2, the capacitor C and the pull-down resistor R3 form a negative pulse monostable circuit, the input end of the first NOT gate A1 is the input end of the negative pulse monostable circuit, the output end of the second NOT gate A2 is the output end of the negative pulse monostable circuit, the output end generates a negative pulse, the negative pulse is connected with the reset end of the main board of the dispatching terminal, and the negative pulse is suitable for resetting and restarting the dispatching terminal. Meanwhile, as the pin 1 and the pin 2 of the RJ-45 plug are connected and grounded, the data receiving end of the serial port of the dispatching terminal connected with the pin 1 of the RJ-45 socket is grounded, so that the dispatching terminal cannot work, and the two pairs of differential lines RX+, RX-and TX+ and TX-of the Ethernet port can work normally. If the serial port on the main board of the dispatching terminal works normally, the RJ-45 plug is pulled out from the RJ-45 socket.
Fig. 8 is a schematic diagram of a standard RJ-45 plug, and similarly, if the standard RJ-45 plug is used to plug into an RJ-45 socket of the dispatch terminal, the 3-pin and the 6-pin of the standard RJ-45 plug have very low impedance, so that the dispatch terminal can be triggered to reset and restart, the serial port cannot work, and the ethernet port cannot work. The railway internal network used by the office machines of the stations, the sections and the departments cannot be connected with the dispatching terminal machine.
The serial port and the Ethernet port of the dispatching terminal can not work simultaneously, and the information security of the railway internal network can be ensured. And because a series of methods such as VPN private network, firewall, network isolation of the wireless communication server, connection of the mobile phone entering the maintenance construction monitoring system once the work is finished, real-time auditing of communication flow of the wireless communication server, wireless communication user and the like are adopted, the information security of the railway internal network and the construction monitoring system can be ensured.
