Abstract
The utility model relates to an on -board diagnostic system signal switching box relates to a signal switching box, especially a signal switching box that is used for on -vehicle automatic diagnostic system OBD. Have the box body, the box body both sides are equipped with the public head of a OBD and the female head of OBD respectively, are equipped with a printed circuit board in the box body, weld the printed circuit board of CPU, relay, peripheral control circuit and row's needle interface on printed circuit board, CPU links to each other with relay, the female head of OBD and peripheral control circuit, female head of ODB and the public head of ODB link to each other with the relay respectively. The female head of OBD is with motorcycle type information transfer to CPU, the break -make of each relay of pin output height level control of CPU to constitute the required communication channel route of signal transmission, realize that the expert of on -board diagnostic system OBD signal box joins in marriage.
Description
Technical field
A kind of OBD Signal transfer box of the utility model relates to a kind of Signal transfer box, especially a kind of Signal transfer box for OBD OBD.
Background technology
Onboard diagnostic system OBD is the operation conditions of monitoring engine and the duty of exhaust gas aftertreatment system at any time, once find that there is the situation that may cause and discharge and exceed standard, can send warning at once.When system malfunctions, trouble light (MIL) or check engine (CheckEngine) emergency warning lamp bright, simultaneously OBD system can by failure message stored in storer, can read relevant information by the diagnostic instrments of standard and diagnose interface with the form of diagnostic trouble code.According to the prompting of diagnostic trouble code, maintenance personal can determine character and the position of fault quickly and accurately.But the interface definition disunity of vehicle causes an OBD signal box to be applied to any one vehicle at present, causes OBD signal box product needed to re-design, wastes a lot of manpower and materials.
Utility model content
The purpose of this utility model provides a kind of onboard diagnostic system Signal transfer box for above-mentioned weak point, overcoming existing onboard diagnostic system OBD signal box can not the defect of wildcard, and this interconnecting device can change by connecting interconnecting device and receiving the instruction that interconnecting device issues the object that relay on-off array reaches adaptive vehicle onboard diagnostic system OBD port definition arbitrarily.
A kind of onboard diagnostic system of the utility model Signal transfer box takes following technical scheme to realize:
Onboard diagnostic system Signal transfer box has box body, box body both sides are respectively equipped with an OBD male and an OBD female, in box body, be provided with a printed circuit board, be welded with the printed circuit board (PCB) of CPU, relay, peripheral control circuits and row's needle interface on a printed circuit; CPU is connected with relay, OBD female and peripheral control circuits; ODB female and ODB male are connected with relay respectively.
Principle of work:
1), after computing machine being connected onboard diagnostic system Signal transfer box, by installing the supporting application program of OBD on computers, the vehicle information wanting to switch is sent to onboard diagnostic system OBD signal box;
2) after onboard diagnostic system OBD signal box receives the vehicle information of computing machine transmission, from the OBD male of onboard diagnostic system OBD signal box, described vehicle information is transmitted to the OBD female of onboard diagnostic system Signal transfer box by data bus, described vehicle information is sent to the CPU of onboard diagnostic system Signal transfer box by the OBD female of onboard diagnostic system Signal transfer box;
3) after the CPU of onboard diagnostic system Signal transfer box receives vehicle information, read and be stored in the vehicle information that prestores in the CPU internal storage binary code corresponding with relay, the break-make that low and high level controls each relay is exported by the pin of CPU, thus the communication channel path of composition required for Signal transmissions.
The connected mode of step 1) onboard diagnostic system OBD signal box and computing machine is USB or WIFI.
Binary code described in step 3) includes the break-make information of relay, and wherein 0 represent relay and do not do action, 1 represents relay does redirect action.
By using onboard diagnostic system Signal transfer box, onboard diagnostic system OBD box can be applied to any vehicle easily, avoid needing because vehicle changes to redesign onboard diagnostic system OBD box, saving great amount of cost and time.
Accompanying drawing explanation
Below with reference to accompanying drawing, the utility model is described in further detail:
Fig. 1 is the fundamental diagram of the utility model onboard diagnostic system Signal transfer box;
Fig. 2 is the inside catenation principle figure of the utility model onboard diagnostic system Signal transfer box.
In figure: 1, onboard diagnostic system Signal transfer box.
Embodiment
With reference to accompanying drawing 1 ~ 2, onboard diagnostic system Signal transfer box has box body, box body both sides are respectively equipped with an OBD male and an OBD female, in box body, be provided with a printed circuit board, be welded with the printed circuit board (PCB) of CPU, relay, peripheral control circuits and row's needle interface on a printed circuit; CPU is connected with relay, OBD female and peripheral control circuits; ODB female and ODB male are connected with relay respectively.
Vehicle information is sent to CPU by OBD female; The pin of CPU exports the break-make that low and high level controls each relay, thus the communication channel path of composition required for Signal transmissions, realize the wildcard of onboard diagnostic system OBD signal box.
The signal converting method of onboard diagnostic system Signal transfer box, comprises the steps:
1), after computing machine being connected onboard diagnostic system Signal transfer box, by installing the supporting application program of OBD on computers, the vehicle information wanting to switch is sent to onboard diagnostic system OBD signal box;
2) after onboard diagnostic system OBD signal box receives the vehicle information of computing machine transmission, from the OBD male of onboard diagnostic system OBD signal box, described vehicle information is transmitted to the OBD female of onboard diagnostic system Signal transfer box by data bus, described vehicle information is sent to the CPU of onboard diagnostic system Signal transfer box by the OBD female of onboard diagnostic system Signal transfer box;
3) after the CPU of onboard diagnostic system Signal transfer box receives vehicle information, read and be stored in the vehicle information that prestores in the CPU internal storage binary code corresponding with relay, the break-make that low and high level controls each relay is exported by the pin of CPU, thus the communication channel path of composition required for Signal transmissions.
Binary code described in step 3) includes the break-make information of relay, and wherein 0 represent relay and do not do action, 1 represents relay does redirect action.
When onboard diagnostic system Signal transfer box uses, the OBD male of onboard diagnostic system Signal transfer box be inserted in the OBD female of onboard diagnostic system OBD signal box of vehicle, the ODB female of onboard diagnostic system Signal transfer box is inserted in the OBD male of onboard diagnostic system OBD signal box of vehicle.
