[0016] The reflector is used to reflect the light emitted by the standard laser rangefinder and the laser rangefinder to be measured, so as to provide the standard laser rangefinder and the laser rangefinder to be measured with distance measurement; the central processor is also connected to the display.

[0017] In the embodiments of the present application, the reflector is generally large in size, capable of covering the light emitted by the standard laser rangefinder and all laser rangefinders to be tested, and reflecting the light; the standard laser rangefinder refers to a laser rangefinder that has been calibrated or adjusted, has good accuracy, and can be used as a detection reference. The batch detection system also includes a memory, a timing switch, and a wireless transmission module, the memory is connected to the central processing unit, the output end of the central processing unit is also connected to the wireless transmission module through the timing switch, and the output end of the wireless transmission module is connected to the remote monitoring center.

[0018] In an embodiment of the present application, the remote monitoring center includes a wireless receiving module, a remote memory, a remote processor and a remote display. The wireless receiving module is used to establish communication with the wireless sending module, receive information from the wireless receiving module, and transmit it to the remote processor. The remote processor is also connected to the remote memory and the remote display respectively.

[0019] In the embodiment of the present application, each RFID tag of the laser rangefinder to be measured has a unique ID number.

[0020] In an embodiment of the present application, after the standard laser rangefinder and each laser rangefinder to be measured are fixed, the distance measurement reference planes of the standard laser rangefinder and each laser rangefinder to be measured are in the same plane;

[0021] In an embodiment of the present application, the reflective plate is mounted on a transmission device, and the transmission device is used to drive the reflective plate to move and adjust the distance between the reflective plate and the standard laser rangefinder and the laser rangefinder to be measured;

[0022] The direction in which the transmission device drives the reflector to move is parallel to the transmission direction of the outgoing light of the standard laser rangefinder and the laser rangefinder to be measured; the transmission device is a transmission belt driven by a stepping motor.

[0023] The working principle of the utility model is as follows: firstly, a standard laser rangefinder is installed at the standard laser rangefinder installation position, and the laser rangefinder to be tested is installed at each laser rangefinder installation position to be tested, so that the emission light transmission direction of the standard laser rangefinder and each laser rangefinder to be tested is perpendicular to the reflector, and the distance from the standard laser rangefinder and each laser rangefinder to be tested to the reflector is equal; when starting the test:

[0024] The outgoing light of the standard laser rangefinder is transmitted to the reflecting plate in a transmission direction; the reflecting plate receives the outgoing light of the standard laser rangefinder and reflects it back to the standard laser rangefinder, and the standard laser rangefinder displays the distance measurement result in its own distance measurement display area; the first camera shoots the distance measurement display area of ​​the standard laser rangefinder and transmits the shooting result to the first microprocessor, and the first microprocessor transmits the shooting result at this time and the real-time time information from the first real-time clock module to the central processing unit, and the central processing unit transmits it to the display for display.

[0025] At the same time, the emitted light of each laser rangefinder to be measured is transmitted to the reflector; the reflector receives the emitted light of the laser rangefinder to be measured and reflects it back to the laser rangefinder to be measured, and the laser rangefinder to be measured displays the distance measurement result in its own distance measurement display area. In addition, in each information detection module, the second camera shoots the distance measurement display area of ​​the laser rangefinder to be measured, and the RFID reader scans the RFID tag of the laser rangefinder to be measured (obtains the RFID number), and the second camera and reader transmit the obtained information to the second microprocessor, and the second microprocessor transmits the shooting result, the RFID scanning result and the real-time time information provided by the second real-time clock module to the central processor, and the central processor transmits it to the display for display;

[0026] In some embodiments, on-site staff can screen out the laser rangefinders to be tested whose errors exceed the allowable range based on the ranging results of the laser rangefinders to be tested with each RFID number and the ranging results of the standard laser rangefinder.

[0027] Since the present application has a transmission device, the distance of the reflector plate can also be adjusted to achieve detection at different distances to obtain more detection data, which helps to improve the accuracy of the staff's judgment; since the present application has multiple information detection modules, it supports simultaneous detection of multiple laser rangefinders to be tested, effectively improving work efficiency.

[0028] In addition, since the present application records the real-time time information when transmitting the measurement results; after the data is stored in the memory, based on the timed opening of the timing switch, the central processor can transmit the data stored in the memory to the wireless transmission module through the timing switch, and then send it to the remote monitoring center, which is stored and displayed by the remote monitoring center; since the data of each measurement has real-time time information, in some embodiments, the staff of the remote monitoring center can compare the laser rangefinder to be tested with the standard laser rangefinder data at the same time, and can screen out the laser rangefinder to be tested that is unqualified or has an error exceeding the allowable range in the remote monitoring center. In the present utility model, there is no need to manually record the data throughout the process, which can avoid errors.
