Further, the load detecting unit is weight sensor.
The beneficial effects of the utility model: the utility model adopt rang sensor detect cargo loading plate and ground and with the relative distance of target location; the control cargo loading plate slows down in default deceleration distance; make cargo loading plate and goods stop at reposefully the target location; and can control rising or falling speed in the preset value speed range; and be provided with annunciator; when the rising or falling speed of cargo loading plate is unusual or overweight, send warning; prevent Accidental occurrence; and; the utility model is simple and reasonable; the convenient making, with low cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is schematic block diagram of the present utility model.
The specific embodiment
Fig. 1 is schematic block diagram of the present utility model, and as shown in the figure, the lift for goods control system that the utility model provides comprises apart from detecting unit, for detection of the cargo loading plate of lift for goods and ground and with the relative distance of target location; Speed detection unit is for detection of the lifting running velocity of the cargo loading plate of lift for goods; Speed control unit is connected in the motor control loop, thereby be used for inbound pacing control signal control motor rotary speed elevator is carried out the speed adjusting; Central Processing Unit (CPU) is used for the signal of receiving range detecting unit and speed detection unit output and exports control signal to speed control unit; The input display unit is used for to the message unit input control information and can demonstrates the demonstration data of information control unit output, and such as the weight of display speed information and goods, described is rang sensor apart from detecting unit; Described speed detection unit is speed sensor; Described Central Processing Unit (CPU) is micro controller system; The utility model adopt rang sensor detect cargo loading plate and ground and with the relative distance of target location; the control cargo loading plate slows down in default deceleration distance; make cargo loading plate and goods stop at reposefully the target location, and can control rising or falling speed in the preset value speed range, and be provided with annunciator; when the rising or falling speed of cargo loading plate is unusual or overweight, send warning; prevent Accidental occurrence, and the utility model is simple and reasonable; the convenient making, with low cost.
In the present embodiment, described lift for goods control system also comprises the input display unit, be used for to the velocity information of Central Processing Unit (CPU) input setting, receive and show the data of the needs demonstration of Central Processing Unit (CPU) output, can show the information of running velocity and the cargo weight of current objective table.
In the present embodiment, described lift for goods control system also comprises the load detecting unit, for detection of the load of the cargo loading plate of lift for goods and to Central Processing Unit (CPU) output load signal, described load detecting unit is weight sensor, described load detecting unit sends load signal to Central Processing Unit (CPU), compared by pay load and the nominal payload of Central Processing Unit (CPU) to cargo loading plate, such as the pay load of cargo loading plate during greater than nominal payload, then Central Processing Unit (CPU) is to the annunciator output alarm signal, and wherein nominal payload is that property calculation according to lift for goods out writes Central Processing Unit (CPU) afterwards.
In the present embodiment, described lift for goods control system also comprises annunciator, is used for receiving the alerting signal of Central Processing Unit (CPU) output and passes through sound or flashing light alarm.
The operation logic of this practical information: with Container Loading on cargo loading plate, being positioned at cargo loading plate load detecting unit starts working, if overweight, the Central Processing Unit (CPU) output alarm signal is to annunciator, alarm equipment alarm, if goods is in the normal weight scope, but lift for goods lifting goods then, when if the goods of lifting runs to 30 centimetres of distance objective positions, rang sensor output range signal, Central Processing Unit (CPU) receives the backward drop-gear box output of the range signal deceleration control signal of rang sensor output, so that the goods pulsation-free is parked in the target location.When the lift for goods cargo loading plate descends, when the distance on distance ground is 40 centimetres, rang sensor is exported range signal to Central Processing Unit (CPU), then export deceleration control signal by Central Processing Unit (CPU) to drop-gear box, make the cargo loading plate safe landing of lift for goods, and in operational process, the running velocity of the cargo loading plate of lift for goods can be adjusted as required, can be in advance by the threshold value of input display unit input speed and show, 30 centimetres and 40 centimetres of above-mentioned deceleration distances are to write in advance central controller, because the running velocity of lift for goods is unhappy, above-mentioned deceleration distance is enough to finish deceleration instruction.
In the present embodiment, the each processing unit in above-mentioned is prior art, and its theory and structure does not repeat them here.
