Abstract
The invention discloses a fault alarm device of magnetic sensor. The fault alarm device is mounted on the magnetic sensor, and consists of a voltage comparer and a fault alarm. The fault alarm device provided by the invention is mounted on the magnetic sensor so as to enable an AGV (automatic guided vehicle) to correct the mistake automatically after the AGV is misled to a wrong route, thereby preventing damages to the AGV and equipment on the AGV, and ensuring safe operation.
Description
Technical field
The invention belongs to the mechanical transport field, particularly a kind of Magnetic Sensor accident warning device that is used 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 accomplish the transport task in the factory building now.AGV utilizes the magnet control carriage walking route of laying in advance; Detect predefined magnetic field route through Magnetic Sensor; Convert field signal into electric signal; Output driving part is the amplifying circuit etc. of faint electric signal through series 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 go 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.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of Magnetic Sensor accident warning device, to reach the purpose of safety work.
For achieving the above object, technical scheme of the present invention is following:
A kind of Magnetic Sensor accident warning device is characterized in that, said Magnetic Sensor accident warning device is installed on the Magnetic Sensor, is made up of voltage comparator and fault alarm.
Preferably, said Magnetic Sensor comprises electromagnetic conversion part and output driving part.
Preferably, said electromagnetic conversion part can be exported electric signal to output driving part, and said output driving part can be to AGV driving governor output electric signal.
Preferably, said voltage comparator can detect electromagnetic conversion part outgoing position electromotive force and output driving part outgoing position electromotive force relatively relatively.
Preferably, said voltage comparator can be according to the logical relation control fault alarm equipment alarm between two outgoing position electromotive forces, and the may command output driving part sends halt instruction to the AGV driving governor.
Pass through technique scheme; Magnetic Sensor integrated circuit module provided by the invention; Through increasing the warning device of Magnetic Sensor faults itself; Played the effect that AGV can correct a mistake automatically after travel route misleads, avoided 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 in the embodiment of the invention, 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
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention will be carried out clear, intactly description.
Magnetic Sensor accident warning device I according to the invention is installed on Magnetic Sensor II; Form 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 the A place electric signal " a " of output driving part 14 outputs and output driving part 14, and the electric signal of a, b relatively.If it is consistent that a, b logically can not reach, then be regarded 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 present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
