Abstract
The utility model discloses a magnetic sensor fault alarm apparatus installed on a magnetic sensor and composed of a voltage comparater and a fault alarm. The voltage comparater controls the fault alarm to alarm and an AGV (Automatic Guided Vehicle) drive controller to stop emergently through comparing two output position potential relations of an electromagnetic conversion part and an output drive part of the magnetic sensor. According to the utility model, an alarm for magnetic sensor self fault alarm is provided, which can automatically correct errors when an AGV is misguided on a driving line and avoids damage possibility of the AGV and equipment carried by the AGV so as to reach the purpose of safe operation.
Description
Technical field
The utility model belongs to mechanical transportation art, and is particularly a kind of for the Magnetic Sensor accident warning device on the AGV.
Background technology
In order to reduce human cost and to enhance productivity, most of factory has realized robotization processing, and the robotization transportation can further improve the performance of enterprises.But with the travelling belt transportation the big shortcoming of floor area is arranged, therefore have a kind of novel Automatic Guided Vehicle (AGV) to finish the interior transport task of factory building now.AGV utilizes the magnet control carriage walking route of laying in advance, detect predefined magnetic field route by Magnetic Sensor, field signal is converted to electric signal, output driving part passes through faint electric signal the amplifying circuit of series etc. then, export one can driving governor work electric signal, can be to the walking road direction channeling conduct of dolly.But once repeatedly occur in the practical application, when the Magnetic Sensor fault, particularly do not have magnetic signal but electromagnetic conversion part when still exporting electric signal, Magnetic Sensor can induce AGV to continue to travel to the zone of not setting pilot signal, causes the damage of AGV and contained equipment.Therefore need the improvement structure badly, avoid above problem.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of Magnetic Sensor accident warning device, to reach the purpose of safety work.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of Magnetic Sensor accident warning device, the Magnetic Sensor accident warning device is installed on the Magnetic Sensor, formed by voltage comparator and fault alarm, Magnetic Sensor comprises electromagnetic conversion part and output driving part, the electromagnetic conversion part can be exported electric signal to output driving part, output driving part can be to AGV driving governor output electric signal, voltage comparator can detect electromagnetic conversion part outgoing position electromotive force and output driving part outgoing position electromotive force relatively relatively, voltage comparator can be reported to the police according to the control of the logical relation between two outgoing position electromotive forces fault alarm, and can control output driving part and send halt instruction to the AGV driving governor.
Pass through technique scheme, the Magnetic Sensor integrated circuit module that the utility model provides, by increasing the warning device of Magnetic Sensor faults itself, played the effect that AGV can correct a mistake automatically after travel route misleads, avoid the possibility of AGV and contained device damage thereof, thereby reached the purpose of safety work.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below.
Fig. 1 is the magnetic sensor arrangement synoptic diagram that accident warning device has been installed.
Numeral among the figure:
I. accident warning device II. Magnetic Sensor
11. voltage comparator 12. fault alarms 13. electromagnetic conversion parts
14. output driving part 15.AGV driving governor
A. electromagnetic conversion part output node B. output driving part output node
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
Magnetic Sensor accident warning device I described in the utility model is installed on Magnetic Sensor II, formed by voltage comparator 11 and fault alarm 12, Magnetic Sensor II comprises electromagnetic conversion part 13 and output driving part 14, and output driving part 14 can be to AGV driving governor 15 output electric signal.
The principle of work of fault alarm is, voltage comparator 11 on the accident warning device I Magnetic Sensor II that can sample goes up the B place electric signal " b " that electromagnetism conversion portion 13 is exported to AGV driving governor 15 to A place electric signal " a " and the output driving part 14 of output driving part 14 outputs, and the electric signal of a, b relatively.If it is consistent that a, b logically can not reach, then be considered as this Magnetic Sensor fault II, just can send alarm command to fault alarm 12, make AGV driving governor 15 out of service simultaneously, ensure the safety of AGV and institute's cargo thereof.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
