Description

Transmission line of electricity GPS makes an inspection tour registering instrument in the location

The utility model relates to a kind of electronic recording equipment, specifically be exactly a kind of device of utilizing the GPS global positioning system technology to combine with electronical record be that registering instrument is maked an inspection tour in transmission line of electricity GPS location.

The tour of electric power transmission line is the important means that guarantees power grid security, and its fundamental purpose is to grasp status of equipment, in time finds defective, eliminates defective, guarantees safety.At present, the line inspection workman has the two kinds of modes of electronic recorder that adopt people's Chinese realistic painting paper record and install recognition device additional on shaft tower in making an inspection tour by base; The former data accurately reaches integrality and has wretched insufficiency, and the latter becomes the serious hindrance that transmission line of electricity is maked an inspection tour popularization at the safety and the aspects such as serviceable life, financial cost of identification equipment always.

For overcoming above-mentioned deficiency, the purpose of this utility model is to provide the GPS location of transmission line of electricity to make an inspection tour registering instrument, so that be used for the arrival time of line inspection of strict guarantee electric power and the canonical record of line defct, reaches the purpose of safety management.

A kind of transmission line of electricity GPS makes an inspection tour registering instrument in the location, and it is characterized in that: it is made up of housing 1 and circuit board 2, and circuit board 2 is inserted in the mounting groove of housing 1.Also be provided with display screen 3, button S on the housing 1 ₁, S ₂, S ₃, S ₄, S ₅Circuit board 2 is formed after being electrically connected by GPS receiving circuit 4, mu balanced circuit 5, CPU single chip circuit 6, keyboard circuit 7, communication interface circuit 8, LCD display module circuit 9, RAM memory circuitry 10 and battery Vdd.

The utility model is compared with the existing record instrument, not only has the advantage that the line inspection workman can observe directly current geographic position information, and in view of the above can on-the-spot identification line name automatically and bar number, can utilize keyword variable input method field notes defective, also be provided with communication interface, give computer management system with the information transmission of field notes, for classification, statistics, arrangement, the printing of data are provided convenience.

Embodiment: make external shell 1 of the present utility model according to Fig. 1, design and produce internal circuit board 2 of the present utility model according to Fig. 2, Fig. 3.GPS receiving circuit 4: be electrically connected with antenna ANTENNA by A01 integrated chip GPS-25LPOEM and form; Be CPU single-chip microcomputer input signal.

Mu balanced circuit 5: be electrically connected with A08 integrated chip TPS7350 by A07 integrated chip TPS7350 and form; Being respectively GPS, CPU provides+5 volts constant voltage dc source.

CPU single chip circuit 6: be electrically connected with A03 integrated chip T4HC373 by A02 integrated chip 8052 and form; The signal data that receives is carried out computing.

Keyboard circuit 7: by button S ₁, S ₂, S ₃, S ₄, S ₅With R ₁, R ₅, R ₆, R ₇Electrical equipment is electrically connected to be formed; For CPU provides feature operation.

Communication interface circuit 8: the NAND gate circuit and the peripheral cell C that are formed by A05 integrated chip MAX202 and A10:A chip 74HC00 and A10:B chip 74HC00 ₁, C ₂, C ₃, C ₄, interface P ₁Being electrically connected the back constitutes; For PC RS232 provides communication port and Transistor-Transistor Logic level translation function.

LCD display module circuit 9: the level shifting circuit of forming by A06 integration module ACM-12864 and three Sheffer stroke gate A10:C chip 74HC00, A10:D chip 74HC00, A11:A chip 74HC00 and by electrochemical capacitor C ₈, resistance R ₂, the reset circuit formed of Sheffer stroke gate A11:B chip 47HC00, adjustable resistance P ₂, P ₃Being electrically connected the back constitutes; For display screen 3 provides shows signal.

RAM memory circuitry 10: be to constitute by A04 chip AT29F040; The defeated next information data of CPU is stored with the flicker of 512K byte, be used to preserve the video data of Chinese character dot matrix storehouse and locator data and setting.Battery Vdd 6V dry cell.

C ₁, C ₂, C ₃, C ₄Be 104PF; C ₆, C ₇Be 20PF; C ₅Be 11MHZ; C ₈Be electrochemical capacitor, 22 μ F, 16V; P ₂, P ₃Be 10K; R ₁Be 1M, R ₂Be 1K; Be divided on the circuit board 2 after above-mentioned each circuit is electrically connected by Fig. 3 and get final product.

Principle of work: because single-chip microcomputer will distinguish the data-signal that receives PC and GPS separately, and an asynchronous communication input port is arranged itself, thereby join the AND circuit of forming by A10:A, A10:B and realize that interface is shared.Because button S ₁Be the locating and displaying key; S ₂Be ESC Escape; S ₃Be navigation key; S ₄Be the defective options button; S ₅Be cursor movement key.

Therefore, after the start, the OEM plate of gps receiver and CPU Single Chip Microcomputer (SCM) system all power up and enter duty, after GPS receives effective satellite positioning signal, data once are transferred to the CPU single-chip microcomputer with per second, receive the valid data several times of GPS when this machine after, making the P17 of CPU is high level, closes the GPS power supply, i.e. (outage of OEM plate 5# power lead), GPS quits work, and presses S this moment ₁Key can show positioning result: comprise line name, bar number, latitude, longitude, time etc.; Press S again ₂Key can be pressed S to mobile display highlighting ₃Key can be revised line name, bar number, presses S ₄Key can be preserved locator data.

If the connection of external PC be connected with the P1 interface finish after, start shooting, press S again ₃Key or S ₄Key is then also closed the power supply of GPS receiving circuit 4; At this moment, the CPU single-chip microcomputer can carry out communication with PC.The CPU single-chip microcomputer is behind the data-signal that identification PC sends, according to the communication request of data answering PC.As: character library, defective, tour staff list, machine number, longitude and latitude, record communication etc.
