Advantage of the present utility model:
1, the tower crane acoustooptic alarm system based on the long distance wireless module has adopted automation control, can remind in time the action situation of operation driver and ground staff's suspension hook, can effectively solve the problem that prior art exists, and saves a large amount of manpowers, and safe and reliable.
2, the acoustooptic alarm system based on the long distance wireless module can meet the demand of many industrial circles, possesses very strong compatibility and commonality, can actv. improves camp site workman's safety, is adapted at the actual industrial field and popularizes.
The utility model has the advantage of the following aspects:
(1) use the SI4432 wireless module to communicate, real realization the process of long distance wireless transmitting-receiving, greatly reduce the bit error ratio;
(2) use DSP as kernel control chip, the pin output voltage can meet the power supply voltage of highlighted LED, without other, increases crystal drive circuit;
(3) wireless alarm system has very strong comformability, and same set of system can be many dissimilar commercial units and served;
(4) this warning is simple to operate, without special technical personnel operation;
With other existing tower crane warnings, contrast: there is no on the market at present similar products.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of tower crane wireless sound light alarm system described in the utility model.
The specific embodiment
The specific embodiment one: present embodiment is described below in conjunction with Fig. 1, the described a kind of tower crane wireless sound light alarm system of present embodiment, it comprises core controller 1, radio transmitters 2, wireless receiver 3, No. two core controllers 4, phonetic alarm 5 and LED annunciators 6;
The switch controlling signal mouth of a described core controller 1 connects the switch controlling signal input end of radio transmitters 2;
A described core controller 1 and radio transmitters 2 are arranged in the tower machine operator's compartment of tower crane;
Described radio transmitters 2 carries out wireless telecommunications with wireless receiver 3;
The wireless signal mouth of described wireless receiver 3 connects No. two core controller 4 wireless signal input ends;
The audio alert control signal mouth of described No. two core controllers 4 connects the audio alert control signal input end of phonetic alarm 5;
The LED alarm control signal mouth of described No. two core controllers 4 connects the LED alarm control signal input end of LED annunciator 6;
Described No. two core controllers 4, wireless receiver 3, phonetic alarm 5 and LED annunciator 6 all are arranged on the tower arm of tower crane.
The specific embodiment two: below in conjunction with Fig. 1, present embodiment is described, present embodiment is described further embodiment one, the controller that the described core controller 1 of present embodiment and No. two core controllers 4 are same model.
The specific embodiment three: present embodiment is described below in conjunction with Fig. 1, present embodiment further illustrates embodiment one and the specific embodiment two, and the main control chip of the described core controller 1 of present embodiment can adopt ARM, DSP or chip microcontroller.
