example 1

[0022] Preferred example 1: such as figure 1 Shown is an image monitoring and anti-collision integrated tower crane safety implementation device, the sensor (101) is connected to the processor (104) through analog and digital signal lines; the sensor (101) is connected to the processor (104) through a bus; The VF conversion chip is converted into a frequency signal and connected to the processor (104); GPS (103) is connected to the processor (104) through the serial port; GSM module or 3G module (105) is connected to the processor (104) through the serial port; the controller ( 102) Connect the processor (104); image monitoring and anti-collision integrated tower crane composed of sensor (101), controller (102), GPS module (103), processor (104), GSM module or 3G module (105) The detection and control part of the safety realization device;

[0023] Processor (107), screen divider chip (108) with OSG, camera (109), LCD / CRT / display (110) constitute the display part of the image...

example 2

[0026] like figure 2 As shown, the sensor (201) is converted into a frequency signal by the VF conversion chip (202) and then connected to the processor (203); the sensor (201) has a temperature sensor, a humidity sensor, a cable length sensor, a weight sensor, and an oil level sensor; VF conversion Chip (202) AD7740, AD7741, AD652, AD654, AD650, ADVFC32, AD537 of ADI Company; processors include ARM M0, M3, M4 series processors, ARM9 series processors, ARM A8, A9 series processors, Microchip series Processors, Freescale PowerPC series processors, TI's M430 series processors and TI's DSP series processors.

example 3

[0027] Preferred example 3: Image monitoring and anti-collision integrated tower crane safety implementation device is composed of a gravity sensor, a cable length sensor, a trolley position sensor, a tower crane angle sensor, and a wind speed sensor;

[0028] The gravity sensor measures the weight of the hanging object, the trolley position sensor measures the distance between the trolley and the center of the tower crane, and the moment of the tower crane is obtained by weight × the distance from the center of the tower crane; when the tower crane reaches a certain value above the rated lifting capacity and rated lifting moment, the device should be able to Send intermittent sound and light alarm to the driver. When the lifting weight and lifting moment reach more than 100% of the rated working capacity, the device will send a continuous and clear alarm to the driver, and only stop the alarm when it falls below 100% of the rated capacity; and stop the lifting of heavy objects...

Abstract

The invention relates to a device for realizing security of an image-monitoring and anti-collision integrated tower crane, in particular to device for realizing security of a tower crane by using a variety of sensors. The invention solves the anti-collision problem in operation of the conventional tower crane. A voltage is generated according to the weight of a heavy object hung on a gravity sensor, a current of 0-20 mA or 4-20 mA is generated by a operational amplifier, the current is converted into a voltage by using a resistor, a sampled voltage is converted into a pulse by using a V / F (Voltage / Frequency) conversion chip, the pulse is transmitted to a processor for processing through an optical coupling isolating circuit, and the processor obtains the weight of the object on a hook of the tower crane according to the number of the pulses sampled in a unit time.
