DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this utility model, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts are within the scope of protection of this utility model.

[0023] Reference Figure 1 and Figure 3 A mobile alarm device for a park entrance and exit includes a suitcase-type main body 1, a radar bracket 2, a high-precision millimeter-wave radar 3, a two-color signal light 4, a mobile power supply 5, and an Internet of Things gateway module 6. The high-precision millimeter-wave radar 3 and the two-color signal light 4 are each installed with at least one set, and the high-precision millimeter-wave radar 3 and the two-color signal light 4 are both mounted on the suitcase-type main body 1 through the radar bracket 2. The mobile power supply 5 is installed in the suitcase-type main body 1 and is electrically connected to the high-precision millimeter-wave radar 3 and the two-color signal light 4. The Internet of Things gateway module 6 is respectively connected to the high-precision millimeter-wave radar 3 and the two-color signal light 4 for signals;

[0024] When in use, combined with the overall function of the alarm equipment, the suitcase-type main body 1 is selected as a mobile platform for carrying high-precision millimeter-wave radar 3, two-color signal light 4, mobile power supply 5, etc. Other commonly used accessories can also be placed in the suitcase-type main body 1, highlighting the compact and convenient design concept, so as to facilitate the daily deployment, transportation and maintenance of the staff. The millimeter-wave radar has the characteristics of high precision and strong anti-interference. By transmitting and receiving millimeter-wave signals, the radar can accurately measure the distance, speed, angle and other information of the target, realize real-time monitoring and tracking of moving targets, and then feed back the signal to the two-color signal light 4 through the color change of the two-color signal light 4 to provide warning indications for vehicles entering and leaving the park.

[0025] In a further embodiment, the radar bracket 2 includes a support rod 21, a mounting bracket 22 and a fixing bracket 23. The support rod 21 is fixedly installed on the trunk-type main body 1 by bolts. The mounting bracket 22 is fixed on the top of the support rod 21. In this embodiment, the mounting bracket 22 is in an inverted "U" shape. Two high-precision millimeter-wave radars 3 are installed in the forward and reverse directions, which can effectively take into account pedestrians and non-motor vehicles moving in the reverse direction. Vertical waist-shaped sliding grooves 221 for installing the high-precision millimeter-wave radar 3 are provided on the outer walls on both sides of the mounting bracket 22. The high-precision millimeter-wave radar 3 is fixed to the mounting bracket 22 by bolts and nuts, which is a prior art and will not be elaborated too much. A plurality of horizontal waist-shaped sliding grooves 222 can also be provided at intervals along the vertical direction on both sides of the mounting bracket 22 located at the vertical waist-shaped sliding grooves 221. When the high-precision millimeter-wave radar 3 slides to the corresponding horizontal waist-shaped sliding grooves 222, the stability of the installation of the high-precision millimeter-wave radar 3 is ensured by passing bolts and nuts through and fixing. The fixing bracket 23 is detachably installed on the top wall of the mounting bracket 22 to install the dual-color signal lamp 4.

[0026] Further, the effective monitoring angle of the high-precision millimeter-wave radar 3 is 120 - 145°, preferably 120°. The maximum effective detection distance is 40 meters, the maximum number of output targets is 63, and the effective monitoring area is determined according to the specific data of the high-precision millimeter-wave radar 3. The output information is the longitudinal distance, lateral distance, longitudinal speed, and lateral speed of each tracked target.

[0027] Refer to Figure 1 , in a further embodiment, two groups of dual-color signal lamps 4 are installed. The two groups of dual-color signal lamps 4 are installed on the radar bracket 2 at a preset angle through the fixing bracket 23. The dual-color signal lamp 4 includes a green signal lamp and a red signal lamp. The preset angle can be set according to requirements or selected according to empirical values. When there is no abnormality in the monitoring area, the green light is on, indicating that it is safe to pass; when a fast-moving target in the area triggers the alarm logic, the red light is on, reminding passing vehicles to slow down and pay attention to observation. The two groups of dual-color signal lamps 4 arranged at an angle can perform simultaneous alarms in multiple directions, improving the alarm efficiency and safety of the alarm device.

[0028] Further, the IoT gateway module 6 is connected to the dual-color signal lamp 4 through a relay (not shown in the figure). The dual-color signal lamp 4 is of a common anode design. The ground wire of the dual-color signal lamp 4 is connected to the normally closed contact point and the normally open contact point of the relay. The mobile power supply 5 is connected to the common end ground of the relay. In this way, one relay can be used to control the signal lamp, and multiple signal lamps can be connected in parallel to the relay for synchronous display. In this embodiment, the use and connection of the relay are prior art and will not be elaborated too much.

[0029] Furthermore, the IoT gateway module 6 is preferably Air724UG, which has an internal integrated 4G communication module and a Bluetooth BLE module. It realizes firmware update and debugging functions through a USB type C interface, and is connected to a high-precision millimeter wave radar 3 through two serial ports. For radars with RS485 bus interfaces, a MAX3485 conversion chip can be used for docking, and for radars with CAN bus interfaces, an ECAN-S01 conversion chip can be used for docking, thereby realizing functions such as radar data access and analysis, alarm algorithm processing, control relays, mobile phone Bluetooth communication interaction, and operation data reporting. At the same time, after inserting a SIM card into the IoT gateway module 6, the device can also use the MQTT protocol to upload working status information to the cloud platform through the 4G network in real time for the platform to perform data analysis and display. In this embodiment, the IoT gateway module 6 with an internal integrated 4G communication module and a Bluetooth BLE module is a prior art and will not be elaborated on.

[0030] Reference Figure 4 and Figure 5 The IoT gateway module 6 can also load an algorithm for filtering alarm prompts, setting the monitoring ranges of the two high-precision millimeter-wave radars 3 to areas A and B. The filtering algorithm includes the following steps:

[0031] (1) Eliminate stationary targets with a speed of 0 in areas A and B;

[0032] (2) Exclude targets that are far away (longitudinal speed > 0) in zone B, that is, only monitor pedestrians and non-motor vehicles (traveling against traffic) that are approaching;

[0033] Alarm generation strategy:

[0034] If the number of targets with speeds exceeding 5 m / s in zones A and B is greater than 0, an alarm is generated;

[0035] Traffic light conversion rules:

[0036] The alarm trigger signal light turns red, and if there is no alarm trigger signal light within 0.6 seconds, it turns green.

[0037] After the above algorithm is loaded into the IoT gateway module 6 in the device, the position, speed and direction of movement of the moving target can be determined based on the monitoring data of the millimeter-wave radar, and the signal light can be driven to display the corresponding warning indication.

[0038] When the mobile alarm device at the entrance and exit of a park of this utility model is actually used, the device can also be connected to the device via Bluetooth of the WeChat applet. The user can conveniently adjust the effective monitoring area of ​​the radar to exclude non-monitoring targets on the motor vehicle lane according to the actual deployment environment; at the same time, the graphical real-time data can be observed on the mobile phone to intuitively evaluate the adjustment effect of the effective monitoring area of ​​the radar.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form or substance. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the present invention, and these improvements and supplements should also be considered as the scope of protection of the present invention. Any technician familiar with this profession can make some changes, modifications and equivalent changes made by using the technical content disclosed above without departing from the spirit and scope of the present invention, which are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of the technical solution of the present invention.
