The radar formed and optoelectronic integration comprehensive survey recognition device have that integrated flexible recognition function is strong, reliability is high to the utility model, the good characteristics of suitable dress property in order to make, and need reliable bus network of high speed of structure.
Above explanation is as can be known, and device needs to solve the problem of multistation high speed reliable communication, requires bus to have common mode inhibition and multistation communication capacity, the utility model proposes the compatible bus of a kind of RS-485 for this reason.RS-422 and RS-485 transceiver adopt balance to send and differential received, therefore have the ability that suppresses common mode interference.It is generally acknowledged that RS-485 supports semiduplex mode, RS-485 develops from the RS-422 basis in fact, so the many electric regulations of RS-485 and RS-422 are similar.And be applied on the Profile fieldbus.RS-485 can adopt two wires and four line modes, two-wire system can realize real multiple spot half-duplex bidirectional communication pattern, and while adopting four lines to connect, can realize point-to-points communication pattern, the same with RS-422, a master (Master) equipment can only be arranged, all the other are from equipment (Slave), but it has improvement than RS-422, no matter on four lines or two wires connected mode bus, can receive 32 equipment more.RS-485 and RS-422 different also be the different of its common mode voltage, RS-485 be-7V is between+12V, and RS-422 at-7V between+7V, RS-485 meets the standard of all RS-422, applies so the driver of RS-485 can be used in the RS-422 network.Embody the compatibility of four line mode RS-485.
The RS-485 standard has only defined a link, but a real RS-485 network reliably also depends on rational application.Reasonably network topology, the continuity of signalling channel, thorough safeguard measure etc.
The utility model adopts four lines to connect, equipment is divided into main equipment and from equipment, from equipment, comprise embedded microcontroller (MCU) as core component, in device, the mixing console host computer is as main equipment, little echo signal acquisition module, platform controller, video processing module etc., as from equipment, are realized point-to-points communication pattern.
In device during equipment connection, not making on a certain section bus to have multi-transceiver to abut against together installs, or long branch line is drawn out to bus, formation is without the tree of center node, but the bus type structure each node is connected in series by a bus, guarantee the continuity of bus characteristics impedance, connect like this, avoid impedance discontinuity point that the reflection of signal occurs.Make the reflected signal in extension line minimum on the impact of bus signals.
Ground connection in device and safeguard measure; the problem with grounding of relevant RS-485 network seldom has data to mention; generally in the deviser, also exist a lot of mistaken ideas; think that the RS-485 interface adopts the differential mode signal transmission need to not carry out the detection signal system for certain reference point, only need the potential difference (PD) detected between two lines just passable.Cause that communication reliability reduces, the interface spoilage is higher.Especially in the situation that working environment is more severe, more strict for the requirement of ground connection.
Ground connection in device has been adopted distinct methods for the varying environment node, outdoor for radar and this class of electro-optical system The Cloud Terrace main frame, floating ground of the employing of severe working environment node technology, namely the circuit ground of system and casing or isolate greatly, for between The Cloud Terrace main frame and cradle head controllor node, adopting isolating interface to cut off ground loop, but still there is a ground wire that the common port of side of isolation is connected with the place of working of other interface
By rational ground connection, reduce common mode interference; Reduce the interface spoilage, reduce electromagnetic radiation (EMI); Improve network reliability.
Transient protective in device, all can produce the glitch that amplitude is very high in the processes such as lightning, and such glitch may have the voltage of hundreds and thousands of volts, but the duration is very short.Often through radar or electrical source importing device, if suitably protection will damage equipment in addition.The device electrical isolation that realizes interface based on elements such as IC transformer technology, optocouplers; utilize transient state straining element (as TVS, MOV, gas-discharge tube etc.) that the transient energy of harmfulness is switched to the earth, the protective separation interface is not punctured by too high transient voltage.
The utility model takes above-mentioned technology to obtain a very firm and compatible bus links of reliable RS-485, and the utility model adopts the high-level communications protocol of setting up oneself on this basis.
How to realize the multi-computer communication function? how distinguishes data frame and address frame, make main frame communicate by letter with a slave or a plurality of slave is communicated by letter.General employing communication means is regardless of " address frame " and " Frame ", by slave computer, indexed variable is set and distinguishes address frame or Frame, and this method implements, and software overhead is not only arranged, and communication speed is slowed down.Although the SCI of host computer communication does not have the TB8 (or corresponding zone bit) of similar MCU, the data that its serial port sends can be made as 11 bit formats that are complementary with the MCU serial data format, different parity check bit and the TB8 of only being.By the way of software, can meet the requirement of MCU communication like this.Method is: concerning host computer, parity bit normally produces automatically, and it is determined according to the odd even situation of 8 bit data, and the author adopts the odd even of manual control 8 bit data, the compensation position using the D7 position of 8 bit data as odd even, to reach the purpose of indirect control parity bit.This method implements, and differentiation " address frame " and " Frame " function are not only arranged, and also retains the original parity function of communication.
The multi-computer communication function is used the automatic address recognition function, realizes one to one, one-to-many communication, and main frame, by calling selected slave addresses SDRI, is selected to communicate by letter with one or more slaves.While using broadcast address, all slaves are all contacted.For energy automatic address recognition function, used two registers to carry out automatic identification address: SADDR means slave addresses, and SADMR means address mask.SADMR is for which defines in SADDR needing to use and which position is not considered, and SADMR can draw the SADDR address with the SDRI logical and, for each slave is carried out to addressing
Device is comprised of a main frame and six embedded MCU, and namely 5, six MCU of slave 0～slave are allocated as follows:
In six slaves, SADDR is identical, but the SADMR difference just can be distinguished six slaves on address: it is 0 that slave 0 requires D0 position (lowest order); It is 0 that 1 of slave requires the D1 position ... it is 0 that 5 of slaves require the D5 position.If main frame is wanted to communicate by letter with slave 0, should send address 11111110.And want to communicate by letter with slave 1, should send address 11111101.If but to send data to simultaneously slave 0 and slave 1, should send address 01111100.Here, the 11111110th, " selecting " address of slave 0 ..., the 11111101st, " selecting " address of slave 2, and 01000000 while sent to six slaves, was " broadcast " address.Six single-chip microcomputer 6 bit address, unnecessary 2, the compensation position using the D7 position as odd even, manual control TB8 is " 1 ", is " 1 " as " address frame " take over party the 9th bit data (RB8), and slave computer can produce serial received and interrupt, and the D6 position retains.MCU adopts interrupt mode to transmit and receive data.
In sum, the radar that the utility model provides and optoelectronic integration comprehensive survey recognition device, integrated radar and optoelectronic device, automaticity is high, detection, tracking, identification and the supervision of realization that can precise and high efficiency to target object.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be looked protection domain of the present utility model.
