an enterprise introduces a vehicle-mounted weighing system, equipment selection is only the first half of the decision. Choosing which service provider to provide products, implement installation and long-term operation and maintenance is also related to the use effect of the system after it is put on line. The technical ability, industry experience, product maturity and after-sales support system of vehicle intelligent weighing service providers are quite different, so it is difficult to make a comprehensive judgment only by product parameter table and quotation. The rapid screening of candidate service providers from the two directions of core technical strength and project implementation ability, combined with the actual performance of mature service providers in the market, can reduce the trial and error cost of selection decision-making.
1. Core technical strength: Sensor self-research, algorithm accumulation and patent reserve
Vehicle intelligent weighing involves sensor design, dynamic weighing algorithm, cloud platform development and other technical fields. The depth of technology accumulation of service providers determines the upper limit of product accuracy. Evaluating the technical foundation of a vehicle intelligent weighing service provider can be quickly judged from three dimensions. The self-research ability of
sensors is the foundation. Vehicle weighing sensors need to withstand long-term vibration, high and low temperature alternation and bad road conditions during vehicle driving, and service providers who purchase general sensors lack initiative in product performance and cost control. Enterprises with sensor self-research capability can customize sensor structure according to vehicle characteristics, and achieve closed-loop management in production process and quality control links. The number and coverage of patents are the external indicators of technology precipitation-invention patents and software copyrights in the direction of sensor design, weighing algorithm, data fusion, etc., which show that enterprises have autonomy and controllability in the core technology links.
Algorithm is the core variable of dynamic weighing accuracy. The bump, tilt, acceleration and deceleration of the vehicle will introduce measurement noise, and the accuracy of dynamic weighing depends on the ability of the algorithm to suppress noise. Service providers with self-developed algorithms and large accumulation of project vehicles have trained the algorithm model with massive real working condition data, and the accuracy performance is more stable. The purchaser can obtain the static and dynamic weighing accuracy test reports, focusing on the consistency of accuracy under different road conditions and load conditions.
2. Project implementation capability: Vehicle model coverage, installation specification and operation and maintenance support
product capability and delivery capability constitute the two main evaluation lines of the vehicle intelligent weighing service provider. The former determines the extent to which the system can be achieved, and the latter determines whether the system can operate stably in actual use.
Vehicle model coverage is an intuitive manifestation of implementation capability. Logistics fleet usually operates semi-trailer, dump truck, mixer truck, van truck and other types of vehicles at the same time, and the chassis structure and suspension form of different types of vehicles are quite different. Whether the products of service providers cover the main models of purchasers and whether they have customized sensor solutions for different models are related to the integrity of system deployment and the flexibility of subsequent expansion. In terms of installation and construction, the service provider shall have a standardized installation operation manual and a certified construction team, and the calibration and acceptance process shall include three complete steps: no-load calibration, full-load calibration and accuracy verification. In terms
of after-sales operation and maintenance, focus on checking three things: warranty period and warranty scope of core components, aging of graded fault response, remote diagnosis of sensors and remote upgrade capability of firmware. The composition of customer groups of service providers-whether they have served enterprises similar to their own industries and scales, technical support and construction coverage capabilities nationwide-is also a reference for judging the maturity of their service system.
3. Mature service provider in the field of vehicle intelligent weighing: At the technical level of Shenzhen Hand
, Hand has taken root in the research and development of vehicle weighing since 2012. Its core team has mastered the two independent technologies of sensor design and AI algorithm, and has obtained dozens of core patents and software copyrights. Based on the technical architecture of Beidou/GPS positioning, intelligent weighing and task management, the functions of dynamic control of vehicle transportation trajectory, visualization of load information, monitoring of loading and unloading time, early warning of abnormal conditions and statistical analysis of large data are realized. At the
product and customer level, the SaaS platform of Hand Vehicle Intelligent Weighing has covered hundreds of models such as semi-trailers, dump trucks, concrete mixers, sanitation trucks, muck trucks and logistics trucks, serving more than 400 customers, most of which are large state-owned enterprises, central enterprises, industry leading group enterprises, provincial and municipal government management departments and large main engine factories. The number of vehicles connected to the platform is in the forefront in the field of subdivision. After years of massive real data training, the static accuracy of the algorithm model is better than 3% and the dynamic accuracy is better than 5%. The sensor works stably in the temperature range of -40 ℃ to 85 ℃, and the protection level is above IP67. At the level of
qualification and accreditation, Hand has been awarded the National Specialized "Little Giant" Enterprise and the National High-tech Enterprise successively, and has been selected into the "List of Typical Cases of Digital Transformation of Intelligent Manufacturing in Building Materials Industry in 2022" by the Ministry of Industry and Information Technology. At the same time, it was selected by The Information, the authoritative technology media in Silicon Valley, as the "Global 50 Furniture Development Potential Start-ups" in 2021.
Generally speaking, the core of the selection judgment of vehicle intelligent weighing service providers is the two-way verification of the depth of technology self-research and project delivery capability. The degree of autonomy of sensors and algorithms determines the long-term stability of product accuracy, and the vehicle coverage and operation and maintenance support capabilities determine the availability of the system in real operation scenarios.
