Description

Technical Field

[0001] The utility model relates to the technical field of light recording instruments, in particular to a portable light recording instrument. Background Art

[0002] In some trading companies' loading monitoring lists, it is occasionally found that container cabinets are opened and stolen on the way to the customer, which will lead to legal disputes. At this time, the customer needs to provide evidence of the theft in the middle of the journey to claim compensation from the shipping company. Some trading companies can only prove that there was no problem with their company's inspection engineers before locking the cabinet, and cannot provide customers with sufficient and effective evidence. If the light recording instrument is turned on and placed in the cabinet before locking the cabinet for monitoring loading, then the change in light intensity and the specific time of the change will be recorded after the cabinet is opened. If used when monitoring loading, some light data can be recorded. If the cabinet is opened and the goods in the cabinet are stolen, it can provide litigation evidence for the customer to a certain extent.

[0003] The above prior art has obvious beneficial effects, but still has shortcomings:

[0004] In the above-mentioned prior art, most of the methods for measuring light intensity use large instruments and record the data in the corresponding test software. Although this method is relatively accurate, the data reading requires a matching computer used for measurement and corresponding test software. The specific use process is relatively cumbersome and inconvenient, and the technical quality of the measurement personnel is required to be high. In addition, most of the instruments for measuring and recording light intensity are large in size. Although the data recording is accurate, due to the large size, it is not suitable for the portable requirements of daily work and life, and cannot be used for monitoring in the cabinet. For this reason, a portable light recorder is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a portable light recorder, which integrates a photoresistor and an analog-to-digital converter into the overall device through an external frame and a device cavity. The device can be placed and used in a relatively small space, and the overall volume is small and convenient to carry. The device automatically records the specific time and duration when the light intensity changes, provides a monitoring process for monitoring cabinets, and records the light data.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 A portable light recorder of this embodiment includes a main body 1, an equipment cavity 2 is arranged inside the main body 1, and a mounting frame 3 is attached to the back of the main body 1. The main body 1 includes an outer frame 101, a cavity 201 is opened inside the outer frame 101, and a display screen 102 is arranged on one side of the outer frame 101, a button 103 is arranged below the display screen 102, and an outer frame plate 104 is arranged on one side of the display screen 102, and slide grooves 105 are attached to both sides of the outer frame plate 104.

[0027] like Figure 1-4 As shown, the main improvement of the utility model is that the photoresistor 207 and the analog-to-digital converter 206 are integrated into the overall device through the outer frame 101 and the equipment cavity 2, which can be placed and used in a smaller space, and the overall volume is small and easy to carry. By automatically recording the specific time and duration when the light intensity changes, a monitoring process is provided for the monitoring cabinet, and the light data is recorded. If the cabinet is opened and the goods in the cabinet are stolen, it provides litigation evidence to a certain extent for the guests; the photoresistor 207 and the analog-to-digital converter 206 in the utility model are both prior art. When in use, the user can set the system through the button 103 and the display screen 102. After keeping the recorder in the open state, the outer frame plate 104 is slid along the slide groove 105 to protect and hide the outside of the recorder, so as to facilitate concealed placement in the monitoring cabinet.

When the instrument is placed inside the monitoring cabinet, if the cabinet is opened, external light enters. At this time, the photoresistor 207 in the photosensitive element cooperates with another resistor to convert the intensity of the projected light into the height of the voltage, and then the analog-to-digital converter 206 converts the electrical signal into a digital signal output and stores it in the TF card in the connected TF card interface 205. The device is powered by a large-capacity lithium battery through the connected lithium battery box 202, ensuring that the instrument is in standby mode when there is no light, and can support long-term operation with low power consumption when there is light, so as to facilitate monitoring and use in the cabinet.
