Description

Technical Field

[0001] This utility model relates to the field of vehicle dispatching equipment technology, and in particular to a GPS intelligent production dispatching device for commercial concrete. Background Technology

[0002] In the production of ready-mixed concrete, the mixing plant uses a GPS dispatching device to determine the location of the concrete mixer trucks, whether there is a traffic jam or material shortage at the construction site, and adjusts the concrete production volume as needed to improve production efficiency.

[0003] Existing GPS dispatching devices are mobile and can be divided into single GPS dispatching devices and base station GPS-integrated dispatching devices. Single GPS devices are suitable for open fields, while base station GPS-integrated devices can maintain good signal even in areas with building obstructions. The performance of single GPS devices limits their applicability, especially after the construction of rural roads has led to urban construction. Single GPS dispatching devices are prone to "signal drift" or "positioning interruption" in areas with many buildings, resulting in dispatching failures. The replacement cost of base station GPS-integrated dispatching devices is higher, and old single GPS dispatching devices are left idle and cannot be used, further increasing replacement costs. Summary of the Invention

[0004] This utility model provides a GPS intelligent production scheduling device for commercial concrete. The GPS positioning module achieves on-demand expansion of base station positioning function through the connection of the upper expansion bracket and the network enhancement module. The base station positioning function of the network enhancement module can effectively supplement the signal shortcomings of GPS positioning in densely populated areas, tunnels, mining areas and other obstructed scenarios, increasing the positioning continuity in complex environments from 60% of traditional single GPS to over 95%, solving the scheduling failure problem caused by "signal drift" or "positioning interruption". For open areas without obstruction requirements (such as plain mixing plants and ordinary construction sites), the GPS positioning module can be used alone without purchasing the network enhancement module, reducing the purchase cost of a single device by 30%. In special scenarios such as mining areas, only targeted enhancement modules need to be installed, avoiding redundant configuration in all scenarios.

[0005] This utility model provides a GPS intelligent production scheduling device for commercial concrete, specifically including a GPS positioning module, a network enhancement module, and an external enhancement antenna base. The network enhancement module is located on the top of the GPS positioning module. The GPS positioning module and the external enhancement antenna base are connected by wiring. The GPS positioning module supports GPS L1 / L2 and Beidou B1 / B3 frequency bands, with a dynamic positioning accuracy of ±3m. The top two sides of the GPS positioning module are recessed with upper connecting grooves. An upper expansion connecting frame is fixedly connected to the top of the GPS positioning module. The bottom of the upper expansion connecting frame has a recessed central connecting hole. Both sides of the upper expansion connecting frame have side connecting slots with an L-shaped slot structure. A data connection male port is located in the middle of the upper expansion connecting frame.

[0006] Furthermore, the network enhancement module is an Internet of Things (IoT) module. The network enhancement module is located through a base station and is a 4G / NB-IoT dual-mode IoT module with a base station positioning accuracy of ±20m. Both sides of the front of the network enhancement module are horizontally slidably connected to front locking blocks, which are L-shaped. A connecting spring is fixed between the front locking blocks and the network enhancement module. A data connection female head is opened at the front of the network enhancement module, and both sides of the bottom of the network enhancement module are vertically slidably connected to rear sliding connecting blocks.

[0007] Furthermore, a connecting spring is fixed between the rear sliding connector block and the network enhancement module, and the data connection female connector and the data connection male connector slide to connect for power supply and data connection.

[0008] Furthermore, the bottom of the network enhancement module has a central connecting hole, which is aligned with the central connecting hole at the bottom of the upper expansion connector. The central connecting hole is used to pass through the signal line between the GPS module and the antenna base, thus concealing the wiring. The central connecting hole can also increase the air circulation channel.

[0009] Furthermore, the front locking block and the side connecting slot are slidably engaged. The front locking block is inserted along the side connecting slot, and after it is in place, the front locking block automatically engages with the side connecting slot under the action of the tension spring. The engagement of the front locking block and the side connecting slot provides longitudinal positioning and fixation, achieving quick locking. The rear sliding connecting block and the upper connecting slot are slidably engaged in the horizontal direction.

[0010] Furthermore, the top of the external enhanced antenna base is rotatably connected to an upper antenna column. The external enhanced antenna base and the upper antenna column are provided with stable damping through a rubber friction pad, ensuring that the angle deviation of the upper antenna column is ≤5° under vibration environment. The upper antenna column operates in the frequency band of 1575.42MHz / 1561.098MHz, with a gain of 28dB, an elevation angle adjustment range of 0°-180°, a rubber friction pad thickness of 3mm, and a damping torque of 10N·m.

[0011] Furthermore, after the connecting spring is pulled, the sliding connecting block moves closer to the network enhancement module.

[0012] This utility model provides a GPS intelligent production scheduling device for commercial concrete, which has the following beneficial effects:

[0013] The GPS positioning module enables on-demand expansion of base station positioning functionality through the connection of the upper expansion bracket and the network enhancement module. The base station positioning function of the network enhancement module can effectively supplement the signal shortcomings of GPS positioning in densely populated areas, tunnels, mining areas, and other obstructed scenarios, solving the scheduling failure problem caused by "signal drift" or "positioning interruption". For open areas with no obstruction requirements (such as plain mixing plants and ordinary construction sites), the GPS positioning module can be used alone without purchasing the network enhancement module, reducing the purchase cost of a single device by 30%. The separation and replacement of the GPS positioning module and the network enhancement module further reduces maintenance costs.

[0014] The connecting spring pulls the rear sliding connecting block to achieve a tight fit between the top of the network enhancement module and the GPS positioning module. The front locking block and the side connecting slot engage to ensure the secure position of the network enhancement module, enhancing its stability inside the vehicle and further improving the efficiency of disassembly and installation compared to traditional bolt connections.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes a GPS intelligent production scheduling device for commercial concrete, including a GPS positioning module 1, a network enhancement module 2, and an external enhancement antenna base 3. The GPS positioning module 1 supports GPS L1 / L2 and Beidou B1 / B3 frequency bands, with a dynamic positioning accuracy of ±3m. The top of the GPS positioning module 1 has recessed upper connecting grooves 101 on both sides. An upper expansion connecting frame 102 is fixedly connected to the top of the GPS positioning module 1. The bottom of the upper expansion connecting frame 102 has a recessed central connecting hole 103. Side connecting slots 104 are provided on both sides of the upper expansion connecting frame 102, and the side connecting slots 104 have an L-shaped slot structure. A data connection male port 105 is provided in the middle of the upper expansion connecting frame 102. The top of the GPS positioning module 1 has the network enhancement module 2, which is an Internet of Things (IoT) module. The network enhancement module 2 uses a base station for positioning. This is a 4G / NB-IoT dual-mode IoT module with a base station positioning accuracy of ±20m. The front sides of the network enhancement module 2 are horizontally slidably connected to front locking blocks 201, which are L-shaped. A connecting spring 202 is fixed between the front locking blocks 201 and the network enhancement module 2. A data connection female connector 203 is provided at the front of the network enhancement module 2. Rear sliding connector blocks 204 are vertically slidably connected to both sides of the bottom of the network enhancement module 2. A central connecting hole 103 is provided at the bottom of the network enhancement module 2, and this central connecting hole 103 is aligned with the central connecting hole 103 at the bottom of the upper expansion connector 102. The central connecting hole 103 is used to pass the signal lines between the GPS module and the antenna base, achieving concealed wiring. The central connecting hole 103 also increases the airflow channel, enhancing heat dissipation. The GPS positioning module 1 and the external enhancement antenna base 3 are connected by wiring. After the connecting spring 202 is pulled, the sliding connecting block 204 moves closer to the network enhancement module 2. The connecting spring 202 achieves a tight fit between the top of the network enhancement module 2 and the GPS positioning module 1 by pulling the sliding connecting block 204.

[0031] The top of the external antenna base 3 is rotatably connected to the upper antenna column 301. The external antenna base 3 and the upper antenna column 301 are provided with stable damping through a rubber friction plate to ensure that the angle deviation of the upper antenna column 301 is ≤5° under vibration environment. The upper antenna column 301 operates in the frequency band of 1575.42MHz / 1561.098MHz, with a gain of 28dB, an elevation angle adjustment range of 0°-180°, a rubber friction plate thickness of 3mm, and a damping torque of 10N·m. The external antenna base 3 is fixed to the top of the mixer truck cab with M8 bolts. The cable is connected to the GPS positioning module 1 inside the mixer truck cab through a waterproof connector. The upper antenna column 301 enhances the signal strength.

[0032] In this embodiment, a connecting spring 202 is fixed between the rear sliding connector 204 and the network enhancement module 2. The data connection female connector 203 and the data connection male connector 105 are slidably connected for power supply and data connection. The base station positioning function of the network enhancement module 2 can effectively supplement the signal shortcomings of GPS positioning in densely populated areas, tunnels, mining areas and other obstructed scenarios, and reduce scheduling failures caused by "signal drift" or "positioning interruption".

[0033] In this embodiment, the front locking block 201 and the side connecting slot 104 are slidably engaged. The front locking block 201 is inserted along the side connecting slot 104. After it is in place, the front locking block 201 automatically engages with the side connecting slot 104 under the action of the tension spring. The engagement of the front locking block 201 and the side connecting slot 104 provides longitudinal positioning and fixation, achieving quick locking. The rear sliding connecting block 204 and the upper connecting slide groove 101 are slidably engaged in the horizontal direction. The disassembly and installation of the GPS positioning module 1 and the network enhancement module 2 are more convenient, further shortening the time for installation, assembly, or maintenance.

[0034] In this second embodiment, based on the first embodiment, the network enhancement module 2 is directly fixed to the GPS positioning module 1 by screws after sliding in, eliminating the need for the front locking block 201, connecting spring 202, and rear sliding connecting block 204. This further reduces costs while reducing the portability of the network enhancement module 2 during installation.

[0035] The working principle of this embodiment is as follows: The GPS positioning module 1 is fixed to the vehicle's windshield with double-sided tape. The GPS positioning module 1 transmits the positioning information to the mixing plant and the cloud-based management system. The ready-mixed concrete plant can display real-time data such as vehicle location, transportation route, concrete parameters (slump, initial setting time, production progress), etc., and supports operations such as issuing scheduling instructions and issuing abnormal warnings, enabling adjustments to concrete production schedules and avoiding situations such as vehicle congestion or material shortages. The GPS positioning module 1 connects to the data connection male port 105 of the upper expansion connector 102 and the data connection female port 203 of the network enhancement module 2 for power and data connectivity. The installation of the network enhancement module 2 enables the base station positioning function. Further expansion is needed. The base station positioning function of the network enhancement module 2 can effectively supplement the signal shortcomings of GPS positioning in densely populated areas, tunnels, mining areas, and other obstructed scenarios. This increases the positioning continuity in complex environments from 60% to over 95% compared to traditional single GPS, solving the scheduling failure problem caused by "signal drift" or "positioning interruption". For open areas with no obstruction requirements, such as plains mixing plants and ordinary construction sites, GPS positioning module 1 can be used alone without purchasing network enhancement module 2, reducing the purchase cost of a single device by 30%. In special scenarios such as mining areas, only targeted enhancement modules need to be installed, avoiding redundant configuration across all scenarios. The ability to separate and replace GPS positioning module 1 and network enhancement module 2 further reduces maintenance costs.

[0036] During the installation of the network enhancement module 2, the front locking block 201 slides into the side connecting slot 104, and the rear sliding connecting block 204 slides horizontally along the upper connecting slot 101. The connecting tension spring 202 pulls the rear sliding connecting block 204 to achieve a tight fit between the top of the network enhancement module 2 and the GPS positioning module 1. The engagement of the front locking block 201 and the side connecting slot 104 achieves horizontal and vertical fixation, ensuring the firmness of the network enhancement module 2 and enhancing its stability in the vehicle. This further improves the efficiency of disassembly and installation compared to traditional bolt connections, and significantly reduces the labor cost of on-site installation and maintenance. The upper antenna column 301 achieves stepless adjustment of the pitch angle from 0° to 90° through rubber friction pads. After adjustment, the damping torque remains at 10 N·m, ensuring that the antenna angle deviation is ≤5° under the long-term vibration environment of the mixer truck, and the signal receiving gain is stable at 28dB, further improving the positioning accuracy in the obstructed area.
