The bidirectional transmission connection device is simple in structure and reasonable in design. The total station can be directly connected with the PDA through the device, the connection between the total station and the PDA is simplified, and bidirectional communication between the total station and the PDA is realized.
Description
Technical field
The utility model relates to a kind of total powerstation and PDA transmitted in both directions coupling arrangement, is specifically related to a kind of confession total powerstation and PDA and carries out matching used data and order transmitted in both directions coupling arrangement.
Background technology
In the engineering survey field, using maximum instrument of surveying and mappings is total powerstation.In actual mapping operations, the various operations of total powerstation to be carried out through the keyboard that total powerstation carries, the data storage of total powerstation collection in worksite is in total powerstation, and data processing can only be carried out in interior industry.Through data line and corresponding software total powerstation is connected with computing machine when interior industry is handled, correlation parameter is set, can the data of storing in the total powerstation be downloaded in the computing machine.This data acquisition and total powerstation mode of operation require data processing in interior industry, to carry out, and therefore have certain limitation, and the whole efficiency of surveying work is also had certain influence.
Palm PC is called PDA again, i.e. peripheral assistant's equipment of computer, its feature richness, use easy, easy to carry.PDA is applied in the engineering survey; Being about to total powerstation is connected with PDA; Can the data in real time of total powerstation field data acquisition be transferred among the PDA, realize true-time operation, the control of PDA to total powerstation simultaneously, industry data processing and field data collection carry out simultaneously in realizing; This data are counted as a kind of more satisfactory field data collection and recording mode with order transmitted in both directions mode, can greatly improve the whole efficiency of surveying work.
At present, mostly the PDA interface is USB interface.Therefore, needs were changed through the RS232-To-USB converter earlier when total powerstation was connected with PDA, and this has limited this data and the use of ordering the transmitted in both directions mode to a certain extent.
Summary of the invention
The utility model provides total powerstation and PDA data and order transmitted in both directions coupling arrangement a kind of simple in structure, reasonable in design to the deficiency that prior art exists.
For realizing above-mentioned purpose, the technical scheme that the utility model provides is:
A kind of total powerstation and PDA transmitted in both directions coupling arrangement; It is characterized in that: this device comprises first interface (J1), USB interface converting unit, second interface (J2) and level conversion unit; Said second interface is connected with level conversion unit with total powerstation respectively; Level conversion unit is connected with USB interface converting unit communication (through serial interface), and said first interface is connected with PDA with the USB interface converting unit respectively.
First interface is a USB interface in the utility model; Second interface is the CON6 interface.
Level conversion unit adopts the chip of Max232.The USB interface converting unit adopts the USB interface conversion chip.
The utility model is compared prior art and is had following advantage:
The utility model is simple in structure, and is reasonable in design, uses this device can realize that total powerstation directly is connected with PDA, and the simplification total powerstation is connected with PDA's, realizes both both-way communications, can improve the efficient of mapping operations.
Description of drawings:
Fig. 1 is the theory diagram of the utility model transmitted in both directions coupling arrangement.
Fig. 2 is the circuit diagram of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing the invention scheme is carried out detailed explanation:
Like Fig. 1, shown in Figure 2, total powerstation of the utility model and PDA transmitted in both directions coupling arrangement comprise the first interface J1, USB interface converting unit, the second interface J2 and four parts of level conversion unit.The second interface J2 is connected with level conversion unit with total powerstation respectively, and level conversion unit is connected through serial interface with the USB interface converting unit, and first interface is connected with PDA with the USB interface converting unit respectively.
The second interface J2 is the CON6 interface in the utility model, is generally 6 needle interfaces; The first interface J1 is a USB interface.
Level conversion unit adopts the chip of Max232.The USB interface converting unit adopts the FT232RL chip.Level conversion unit is used for converting Transistor-Transistor Logic level to the RS232 fiduciary level; The USB interface converting unit is used for converting the voltage standard of usb protocol regulation to the TTL normal voltage.LED lamp D1, D2, D3 are used to show the duty of transmitted in both directions coupling arrangement among Fig. 2.
Total powerstation connects the transmitted in both directions coupling arrangement through the CON6 needle interface, and PDA connects the transmitted in both directions coupling arrangement through USB interface.
