Description
Technical field
The invention belongs to Internet of Things application, be specifically related to a kind of elevator faults checking system and method.
Background technology
Require according to " Code for design of dwelling houses ": " house of height more than more than 16 meters on 7 layers and above house or the outdoor design ground of resident family's entrance floor identity distance must arrange residential lift." at present, 6 layers and following residential building are the main flows of China's dwelling construction, occupy the building area of more than 80%.According to national Specification, resident design should meet the relevant regulations of existing national standards " Code for fire protection design of buildings " (GBJ16) and " Code for fire protection design of high rise buildings ", building is high is the house of 7 ~ 9 floor, allows the elevator of outfit 1 non-fire protection requirement; Building is high above more than 12 floor, join 2 elevators, and 1 elevator wherein must can hold 1 pair of stretcher.The building code clear stipulaties in some places, in residential building, the quantity of elevator will match with the number of resident family.In recent years, along with growing continuously and fast of Chinese real estate, there is flourishing as never before scene in China's elevator industry.Analyze the high speed development of the development tendency of real estate in recent years, particularly commercial residential buildings, residential lift demand will be made to continue soaring.
But elevator brings easily simultaneously, also there are some hidden danger, the haulage cable of such as lift car has been used of a specified duration to wear and tear, may rupture, and elevator accelerates suddenly to fall and waits accident.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of elevator faults checking system based on zigbee network and method, whether complete for detecting hawser, to change in time.
Technical scheme of the present invention is: the elevator faults checking system based on zigbee network provided by the invention, comprise master controller, for detect steel cable pulling force steel cable pull force calculation module, for detecting the LOAD CELLS whether having people in car, the motor drive module connecting master controller and receiving the upper computer of master controller alarm message, steel cable pull force calculation module transmits information by aggregation node to master controller, and LOAD CELLS connects master controller.Described master controller is communicated by GPRS network with between upper computer.Described checking system also comprises alarm module, and alarm module connects upper computer.Described alarm module comprises short message of mobile telephone for alarm module.
The present invention has following good effect: the service condition that can detect steel cable, changes in time when wearing and tearing; Exception detected when elevator drops suddenly, start emergency rescue mechanism; Adopt GPRS network to communicate between master controller with upper computer, GPRS network continuously online, long transmission distance, speed of transmission are fast.Adopt the mode of zigbee network between pull force calculation module and master controller, the bothering of installation work and equipment moving, zigbee favorable expandability can be exempted, flexible for installation.Information transmission distance is exaggerated by aggregation node by this system, can include all elevators of a community in monitoring mechanism, reduces the input of human resources.
Accompanying drawing explanation
Fig. 1 is the system construction drawing of the specific embodiment of the invention.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and principle of work, manufacturing process and operation using method etc., be described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to design of the present invention, technical scheme.
Based on the elevator faults checking system of zigbee network, comprise steel cable pull force calculation module, master controller, alarm unit, motor-drive circuit, LOAD CELLS and upper computer; Steel cable pull force calculation module is for detecting the pulling force of steel rope, and steel cable pull force calculation module sends data to aggregation node by zigbee network, and data transfer to primary controller to carry out analyzing and processing by aggregation node.
Arrange the pulling force fluctuation range of steel cable pull force calculation module at master controller, master controller sends signal to upper computer, and upper computer connects alarm module, when pulling force goes beyond the scope, sends alerting signal, goes maintenance before reminding technology personnel.Pull force calculation module uses pulling force sensor, and steel rope is generally twisted together by a few strand steel wire rope, and every root steel rope is established a sensor, and when wherein one wire cable rupture, the pulling force of each sensor can change.Master controller sends a speed-slackening signal to motor-drive circuit, stops the operation of elevator.
Master controller is also connected with LOAD CELLS, LOAD CELLS is located at cab interior, judge whether have people in elevator by the change detecting car weight, if elevator is in operation tension variations to be detected, judging whether have people in elevator, have people then by elevator parking at the nearest floor being about to arrive, after opening elevator door and out of service, generally, a stay cord fracture can not have influence on the paralysis of whole system, and passenger can be allowed to leave.Elevator is in operation and occurs that pulling force fluctuates, but in car during no one, can be out of service immediately.
Elevator, in operational process, first raises speed, and then travels at the uniform speed, and finally slows down again, passes through formula
F-mg=ma,
Wherein, F is wire rope traction power, and m is car mass, g is acceleration due to gravity, a is car acceleration, known, and wire rope traction power changes around car gravity, | when a| is maximum, tractive force is maximum.So if a setting tractive force fluctuation range, exceed the mechanism that this scope is just reported to the police, under the unforeseen circumstances that car falls suddenly, pull force calculation module also can detect unforeseen circumstances, takes urgent measure.
Adopt GPRS network to communicate between master controller with upper computer, GPRS network continuously online, long transmission distance, speed of transmission are fast.Adopt the mode of zigbee network between pull force calculation module and master controller, the bothering of installation work and equipment moving, zigbee favorable expandability can be exempted, flexible for installation.Information transmission distance is exaggerated by aggregation node by this system, can include all elevators of a community in monitoring mechanism, reduces the input of human resources.
Pulling force sensor used by the present invention and weight sensor have application more in life, arrange that to make as the software used by triggering command outside scope be prior art in threshold value, and innovative point of the present invention is architectural feature.Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
