Drawings
Fig. 1 is a logic control diagram of a smart seat belt according to an embodiment of the present invention.
Detailed Description
The following embodiments are merely exemplary, and are not to be construed as limiting the technical aspects of the present invention.
In the embodiment of the application, an intelligent safety belt interlocking system and a control method when a glue removing cabinet above a butyl rubber glue removing operation platform is used for manual glue removing are described as an example, but the technical scheme of the application is not only applicable to the field, and the technical scheme is applicable to all places or fields needing safety belts.
The application provides an intelligent safety belt interlocking system, including safety belt, buckle sensor, torque sensor and controller. This application removes gluey work platform at butyl rubber and sets up safety guide, in other places of this application, can set up any device that can be used for fixed safety belt as required, all is suitable for.
Parallel safety guide rails are fixed at the two sides of the glue removing cabinet above the butyl rubber glue removing operation platform and 3 meters away from the cabin door of the glue removing cabinet, and ropes of the safety belts are arranged on the safety guide rails and slide on the safety guide rails.
The buckle sensor is arranged in the buckle of the safety belt and is in electric signal connection with the controller, when the buckle of the safety belt is fastened, the buckle sensor sends a signal to the controller, otherwise, the buckle sensor does not send a signal to the controller, and at the moment, the controller cannot detect the signal of the buckle sensor.
The safety belt is provided with torque sensor at the junction of safety belt and safety guide for detect the pulling force of safety belt, if the pulling force that the controller detected torque sensor lasts and exceeds the setting value, show that the operating personnel takes place to fall, controller control screw rod hydroextractor is shut down, and the safety belt guarantees that the operating personnel can't continue the tenesmus simultaneously. When the controller is applied to other places, if the rotating equipment can be in electric signal connection with the controller, the controller can send a stop signal when a torque sensor of the controller exceeds a set value in equipment time.
Install automatic lock on the hatch door of removing gluey cabinet, in the technical scheme of this application, automatic lock is electromagnetic lock or controllable bolt lock, automatic lock and controller signal of telecommunication connection.
The alarm device is an audible and visual alarm device and is in electric signal connection with the controller.
Meanwhile, a monitoring device is arranged above the butyl rubber degumming operation platform and is in electric signal connection with a remote controller, so that the safety state of an operator is monitored.
As shown in fig. 1, the present application further discloses a control method of a smart seat belt, using the smart seat belt interlock system of any one of the above, including the steps of:
s1, the worker enters the operation platform and wears the safety belt, and in the embodiment, the worker enters the butyl rubber degumming operation platform.
S2, the controller detects the signal of the buckle sensor, the buckle sensor can send the signal after the buckle of the safety belt is fastened, and the signal can be detected by the controller at the moment, otherwise, the controller cannot detect the signal of the buckle sensor. If the controller can not detect the fastener sensor signal, then the controller does not send safe signal, in this application, the controller does not send the signal of opening to automatic lock, and the operation personnel can not get into the normal operation of removing the gluey cabinet. If the controller detects the buckle sensor signal, the controller sends a safety signal, namely an opening signal is sent to the automatic lock, the automatic lock is unlocked, the cabin door is opened, and the operator enters the glue removing cabinet to normally operate.
After the normal operation of the operator is finished, the operator unlocks the safety belt, when the signal of the buckle sensor can be detected originally, the controller cannot detect the signal of the buckle sensor, the operation is finished, the controller sends an alarm signal to the alarm device, the cabin door of the glue removing cabinet is closed after the operation is finished, and the safety belt returns to a complete state.
S3, in the normal operation process of the operator, the controller detects whether the tension signal of the torque sensor is greater than a set value, in this embodiment, the set value is 25kg as an example, if the torque is not greater than 25kg, the operator performs normal operation, the controller does not send a control signal, if the controller detects that the signal of the torque sensor is greater than 25kg and lasts for more than 5 seconds, it is indicated that the operator may fall, and the controller sends a stop signal to the butyl rubber screw dehydrator and sends an alarm signal to the alarm device and the remote control room. If the controller detects that the signal of the torque sensor is more than 25kg but the time is less than 5 seconds, the accidental tension is displayed to be too large, and the falling risk of the operating personnel is avoided, and at the moment, the controller does not send a stop signal to the screw dehydrator of the butyl rubber and does not send an alarm signal.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
