A kind of elevator wireless communication system
Technical field
The present invention relates to the elevator field, relate in particular to a kind of elevator wireless communication system, can be applied to vertically move elevator and slant operation elevator.
Background technology
In recent years, China's economic construction increases fast, and for elevator industry has brought unprecedented opportunity, along with the fast development of industry, the lift product of China has occupied the share of the whole world more than 50%, and elevator industry association statistics shows that China's elevator industry is fast-developing.Elevator demand speedup surpasses 15% at present; The space is huge; The elevator quantity that China puts on record on the regular payroll is just to be higher than 20% speed increment every year, and early China has just become the maximum country of global elevator recoverable amount several years ago, at present China with terraced quantity above 1,600,000.As maximum elevator market, the whole world, China's elevator output maintenance increases.
Elevator is a kind of electromechanical appliance of complicacy, relates to people's personal safety, along with the development of Chinese Urbanization's, sharply increases in the quantity with elevator, and the safety of elevator, reliability become the focus that people pay close attention to.The beneficial effect that elevator is installed be safety more reliably, more energy-conservation, more convenient trip, improved quality of residents'life.
Along with the growth of economy and the raising of people's living standard, elevator is just becoming the indispensable equipment of building from the former equipment that is used as top-grade building, adds the market keen competition, requires the elevator manufacturing cost further to reduce.
That control signal transmission between existing lift car and the control housing is adopted is wired, with the flat cable of lift car servo-actuated operation; Cost is higher; Increased installation procedure, and because cable with the car high-speed cruising, there is the danger that interferes with the elevator hoistways inner component.
Summary of the invention
To above-mentioned defective; The object of the present invention is to provide a kind of elevator wireless communication system; Reduced that elevator carries out wire signal when transmission cable through the servo-actuated cable in operational process and mutual possibility of interference takes place the hoistway parts; Reduced elevator manufacturing and cost of installation, improved the safety and the reliability of elevator operation, made elevator more go a step further towards intelligent direction.
In order to address the above problem; Technical scheme of the present invention is; A kind of elevator wireless communication system is provided; Comprise control housing unit and lift car unit; Described control housing unit comprises interconnective elevator control cabinet, signal control and conversion micro controller system, rf receiver and transmitter, and described lift car unit comprises interconnective elevator car controller, signal control and conversion micro controller system and rf receiver and transmitter, and the type of transmission between described control housing unit and the lift car unit is a transmission over radio.
In preferred embodiment of the present invention, be connected through communication bus between described elevator control cabinet and signal control and the conversion micro controller system.
In preferred embodiment of the present invention, be connected through communication bus between described lift car device and signal control and the conversion micro controller system.
In preferred embodiment of the present invention, described communication bus is the CAN bus.
Elevator wireless communication system of the present invention; Under the condition that meets the elevator safety manufacturer's standard; Make control signal between lift car and the elevator control cabinet realize the transmission over radio of data by the servo-actuated cable transmission; Improve the safe reliability of elevator greatly, practiced thrift resource and cost, promote elevator further towards intelligent development.
Description of drawings
Fig. 1 is the structured flowchart of elevator wireless communication system one preferred embodiment among the present invention;
Being labeled as in the accompanying drawing: 1, control housing unit, 2, the lift car unit.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
As shown in Figure 1, be the structured flowchart of elevator wireless communication system one preferred embodiment among the present invention, this elevator wireless communication system comprises control housing unit 1 and lift car unit 2.Wherein, control housing unit 1 comprises interconnective elevator control cabinet, signal control and conversion micro controller system, rf receiver and transmitter; Lift car unit 2 comprises interconnective elevator car controller, signal control and conversion micro controller system and rf receiver and transmitter.Control housing unit 1 and the type of transmission between the lift car unit 2 among the present invention are transmission over radio.
Be connected through communication bus between elevator control cabinet among the present invention and signal control and the conversion micro controller system; Be connected through communication bus between lift car device and signal control and the conversion micro controller system.Wherein, communication bus is the CAN bus.
This elevator wireless communication system is a kind of wireless communication method based on CAN bus and radio-frequency technique; Realized the wireless transmission scheme between lift car control signal and the main elevator control cabinet; Reduced that elevator carries out wire signal when transmission cable through the servo-actuated cable in operational process and mutual possibility of interference takes place the hoistway parts; Reduce elevator manufacturing and cost of installation, improved the safety and the reliability of elevator operation.
Elevator control cabinet refers to control and drives the equipment that elevator moves.
CAN (Controller Area Network) bus is claimed controller local area network again, is that German Bosch company is for solving a kind of serial data communications busses that control numerous in the modern automobile and the data exchange between the testing tool are developed.
Signal control and conversion micro controller system are meant the micro controller system that is used for carrying out between CAN signal and the RF receiving and transmission module Data Transmission Controlling and data transfer, can realize its function through software programming.
Rf receiver and transmitter is meant the high-performance data transceiver module based on microwave radio.
Elevator car controller is meant the micro controller system that is used to handle passenger's instruction and other control signals in the car at the car position of elevator.
The elevator wireless communication system that the present invention discloses; Under the condition that meets the elevator safety manufacturer's standard; Make control signal between lift car and the elevator control cabinet realize the transmission over radio of data by the servo-actuated cable transmission; Improve the safe reliability of elevator greatly, practiced thrift resource and cost, promote elevator further towards intelligent development.
The above; Be merely the specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
