The invention discloses a bed body fatigue test controller used for medical instruments. The bed body fatigue test controller used for the medical instruments comprises an overcurrent and reverse direction protection circuit. The overcurrent and reverse direction protection circuit is connected to a filter circuit. The filter circuit is separately connected with an output control circuit, a drive circuit and a micro processing chip which can emit motion instructions. The micro processing chip is connected with the drive circuit. The drive circuit is connected with the output control circuit. The output control circuit can control a plurality of bed bodies. The bed body fatigue test controller used for the medical instruments of the invention is characterized by being simple in circuit, stable in performance and high in inspection efficiency.
Description
Technical field
The present invention relates to technical field of medical instruments, specifically bed body torture test controller for a kind of medicine equipment.
Background technology
At present, the inspection of bed body performance generally all realizes by quality inspection personnel repeatable operation bed body controller, and when larger in batches, quality inspection personnel workload is larger, and the number of times of torture test and difficult quality guarantee finally can affect the quality of product.
Summary of the invention
The object of the invention is in order to overcome above deficiency, provide that a kind of circuit is simple, stable performance, a bed body torture test controller for medicine equipment that checking efficiency is high.
Object of the present invention is achieved through the following technical solutions: bed body torture test controller for a kind of medicine equipment; comprise overcurrent, reverse protection circuit; described overcurrent, reverse protection circuit are connected with the micro-chip processor that filtering circuit is connected with respectively output control circuit, driving circuit and can sends action command; micro-chip processor is connected with described driving circuit; driving circuit is connected with described output control circuit, and output control circuit can be controlled many bed bodies.
Further improvement of the present invention is: filtering circuit is realized filter function; 5V power supply after overcurrent, reverse protection circuit and filtering circuit for other circuit provides power supply; by the normally opened contact output bed body control signal of the relay in output control circuit; micro-chip processor is realized output and is driven function; signal after programming is set is delivered to driving circuit; signal output after output control circuit afterwards, is realized and is controlled many bed bodies simultaneously by multidrop line.
The present invention compared with prior art has the following advantages:
The present invention sends action command by micro-chip processor; the work of driving relay; realize bed body automatic operation, output control circuit can pass through the switching control line of several one-to-two, controls many bed bodies simultaneously and carries out torture test; checking efficiency is high; each actuation time, number of times all can be set arbitrarily by program, adopt 5V Power supply, have short circuit, reverse connecting protection, the work of employing ULN2003 chip drives 5V relay; circuit is simple, stable performance.
accompanying drawing explanation:
Fig. 1 is module diagram of the present invention;
Fig. 2 is electrical schematic diagram of the present invention;
Number in the figure: 1-overcurrent, reverse protection circuit, 2-filtering circuit, 3-output control circuit, 4-driving circuit, 5-micro-chip processor, 6-bed body.
