Description
Technical field
The utility model relates to a kind of railway locomotive hand-held version information checking device.
Background technology
LKJ (train operation monitoring device) is the important safety equipment of Chinese train operation control system system, and the correctness of LKJ software version information is closely related with traffic safety.Because various factors influence, it is frequent that the LKJ chip is changed task, changes place and replacing personnel and disperse, and causes the LKJ chip to change the work management confusion, to change the progress statistical error big, and the accident symptom of a trend that drain, miss change etc. has a strong impact on traffic safety takes place repeatedly.The change the outfit height of quality of chip directly affects railway security.
The utility model content
The utility model purpose is to provide a kind of software version information and wireless transmission of obtaining in real time, and timely and server end is compared the on-the-spot result's that changes the outfit hand-held version information checking device.
For achieving the above object, the utility model can be taked following technical proposals:
Hand-held version information checking device described in the utility model, it comprises display module, radio transmission control module, interface module, keyboard input module, power supply and the charging process module that is electrically connected with the CPU control module, and the output terminal of described power supply and charging process module is electrically connected with display module, radio transmission control module and interface module respectively.
Described interface module comprises USB interface, CF card, IC-card interface, network interface, serial ports and wired modem interface.
The utility model advantage is directly to read the version information of LKJ, and send to ground communication controller (server end) in real time by radio transmission control module and check, and return check result in real time, to remind the outfit personnel with the form of sound and light alarm if any the mistake that changes the outfit, the accident that fundamentally avoided draining, miss change etc. has a strong impact on train traffic safety takes place.
Description of drawings
Fig. 1 is a schematic block circuit diagram of the present utility model.
Fig. 2-1, Fig. 2 the-the 2nd, the circuit theory diagrams of power supply described in the utility model and charging process module.
Embodiment
Shown in Fig. 1, Fig. 2-1, Fig. 2-2, hand-held version information checking device described in the utility model, it comprises display module, radio transmission control module, interface module, keyboard input module, power supply and the charging process module that is electrically connected with the CPU control module, and the output terminal of described power supply and charging process module is electrically connected with display module, radio transmission control module and interface module respectively.
The CPU control module is the control core of system; CPU adopts plate to carry embedded high-performance 16 bit processors, this processor inside be 32 RISC frameworks and with 80C186 processor compatibility, have high performance, dominant frequency is up to 50MHz, the built-in Ethernet of 100M, and support the SDRAM of 1MB.
The display message that the CPU control module that receives display module transmits also is presented on the display screen, more intuitively the display device current state; Display adopts 2.8 cun OLED display screens with advantage such as frivolous, that the visual angle is wide, 320*240 resolution, 262K look.Adopt 8 bit parallel interfaces to be connected with the cpu data mouth, CPU provides read/write, chip selection signal simultaneously.The power supply that display backlight needs is ± 5V that the power supply that display chip needs is 3.3V.Because power consumption backlight is very big, may disturb CPU to start in the moment of starting shooting, also relatively waste battery electric quantity.Therefore giving in the backlight power supply of display screen has increased delay control circuit, and time-delay back CPU starts, and screen is set to black, has avoided the directly white screen of start, has the advantage of saving battery electric quantity.
Radio transmission control module adopts the MC39I module to communicate, GPRS transmission and SMS are provided, the LKJ version information that is used for obtaining is sent to ground communication controller (server) by wireless transmission method and compares, server feeds back to this device with comparison result with short message mode, the result who reminds the outfit personnel this time to change the outfit.
Interface module comprises CF card, USB interface, IC-card interface, network interface, serial ports and wired modem interface, be used to connect external unit and communication, for this device provides abundant external connecting interface, be connected conveniently to store data, unload database and to carry out network.
Keyboard input module adopts 4 * 5 thin film switches, and for the utility model provides the interface of man-machine interface, the outfit personnel can and send instruction by thin film switch button input inquiry.
This device adopts the powered battery mode that working power is provided, and the charge circuit of battery.Consider reusing of battery, select poly-lithium battery for use.Battery capacity 4000mAh, model E855085.Cross and put deboost 3.0V, charging deboost 4.2V.
Power supply and charging process module comprise switching on and shutting down control circuit, battery, charging process circuit, battery management circuit and DC/DC change-over circuit, have functions such as battery supply feed protection activation, electric weight indication, low electric weight warning and power down protection; Shown in Fig. 2-1, figure-2, the battery charge process chip adopts LTC4054, and this chip is the linear charger of a complete single-unit lithium ion battery steady current/constant voltage.Its SOT encapsulates the ideal that makes LTC4054 become portable use with less outer member number and selects.LTC4054 can be fit to USB power supply and adaptor power supplies work.Owing to adopted inner PMOSFET framework, added anti-down charging road, so do not need external detection resistor and isolating diode.Hot feedback can be regulated charging current, so that under high-power operation or high ambient temperature condition chip temperature is limited.Charging voltage is fixed in 4.2V, and charging current can be carried out outer setting by a resistor.When reducing to setting value 1/10 after charging current is reaching final float charge voltage, LTC 4054 will stop charging cycle automatically.Charging current selection resistance R 37 resistances are 1.8K in the circuit, and the charging current actual measurement is for about 500mA, and use can meet the demands.The function of diode D10 is to reduce the input voltage of LTC4054, and then reduces the oneself power consumption of LTC4054.Resistance R 36 and luminotron D8 form the charged state pilot lamp, and D8 is bright in the charging process, and along with the end of charging process, deepening does not gradually work at last, and the expression charging is finished.If charging voltage is lower than 2.9V, then charger enters the trickle charge pattern.In this pattern, LTC4054 provides about 1/10 setting charging current, so that current/voltage is promoted to the level of a safety, thereby realizes full current charges.When charging voltage rises to 2.9V when above, charger enters constant-current mode, and provide constant charging current to battery this moment.When charging voltage reached final float charge voltage (4.2V), LTC4054 entered constant-voltage mode, and charging current begins to reduce.When charging current is reduced to 1/10 of setting value, charging cycle finishes.
