Problems solved by technology

Since the camera is installed at a certain angle, and the beam is observed through reflection, it is not intuitive, and the trolley cannot be precisely positioned. The uncertainty of the specific position of the trolley will bring cumbersome operations to the operators in the operating room. The degree of intelligence in the process is not high, which increases the labor cost of operators and ultimately leads to low irradiation efficiency

Embodiment 1

[0059] Embodiment one, refer to the attached figure 1 The present invention is applied to the positioning schematic diagram under the "scientific experiment mode". When there is no trolley in the irradiation area, a certain margin is set in the program considering the shaking of the trolley, and the distance measured by the laser ranging sensor is the west wall The distance to the east wall is within the range of L±100mm, where L is the actual on-site measurement distance, which is 9000mm in this embodiment.

[0060] When the trolley N1 enters the irradiation area from the entrance of the irradiation area and runs to the straight track, the laser ranging sensor T1 measures the time t when the emitted laser is reflected by the stainless steel baffle 1 at the rear, according to the formula (c is the speed of light, t is the time from when the laser is emitted to when it is received) to calculate the distance D, and also to set the parameters in the control program according to ...

Embodiment 2

[0062] Embodiment two, refer to the attached figure 2 The present invention is applied to the positioning diagram in the "processing and production mode". During irradiation processing and production, multiple cars are running under the beam. To ensure that the radiation dose is consistent, the speed of the car is fixed and set to v. If the speed of the car is not fixed, the distance difference measured twice by the distance measuring module can be used. Calculate the current speed of the car. When there is no trolley in the irradiation area, consider the shaking of the trolley, and set a certain margin in the program. The distance measured by the laser ranging sensor is within the range of L±100mm from the west wall to the east wall, and L For the actual on-site measurement distance, it is 9000mm in this embodiment.

[0063] When the car N 1 When entering the irradiation area from the entrance of the irradiation area and running to the straight track, the laser ranging se...

Abstract

The invention discloses a method and device for real-time monitoring of the trolley position under a beam of an irradiation system. The method comprises the steps that an upper machine transmits a mark signal; a lower machine receives the mark signal and selects a ranging subprogram according to the mark signal; and the upper computer performs the information processing according to the mark type.The device comprises a control module and a positioning module. The control module comprises the upper machine and the lower machine, and the positioning module comprises a laser ranging sensor, a reflector and a photoelectric switch. The device further includes a beam protection module which includes a stainless steel box, ultra-clear glass, a pressure gauge and a breather pipe. The method and the device reduce the workload of irradiation system operators, have precise irradiation time, reduce the energy loss and enable the operation to be more convenient and quick, and work efficiency and energy utilization are improved.

Description

technical field [0001] The invention relates to a real-time laser positioning technology for moving objects, in particular to a method and device for real-time monitoring of the position of a trolley under an irradiation system beam. Background technique [0002] Cobalt source irradiation and accelerator irradiation are widely used, and irradiation applications have penetrated into various fields, such as industrial wastewater and waste gas treatment, irradiation sterilization of medical equipment, biological breeding, food sterilization and preservation, etc. Products ranging from aerospace cables to instant noodle seasoning, bagged cooked food, etc. have been irradiated. The under-beam transmission devices of the irradiation system are roughly classified into three categories: wire transmission devices, sheet and membrane transmission devices, and trolley transmission devices. The position of the conveying device under the wire, sheet and membrane beam is relatively fixed...
