The evaluation of bids for public resources trading projects is the core service of the Public Resources Trading Centre, and its trading links are of great concern to all parties involved in the transaction. As the "referee" of the evaluation of bids, the professionalism and fairness of the evaluation of bids play a crucial role in the whole evaluation process.

The base is mainly responsible for the construction of the electronic bid evaluation system, remote monitoring system, bid evaluation expert extraction system, data statistical analysis, and the informationization of public resources trading violations and bad reputation records, and for assisting relevant departments in the supervision and inspection of the whole process of trading activities in public resources trading centres. etc. In order to further strengthen the entry management of bid evaluation experts and promote the improvement of quality and efficiency of bid evaluation work, the base especially introduced Woxu Wireless's UWB high-precision personnel positioning system to intelligently upgrade the base. The system can record the trajectory and abnormal behavior of bid evaluation experts after arriving at the site throughout the whole process, so as to reduce the interference of external factors in the bid evaluation process and maintain a healthy transaction order.

Pain points, management problems before the upgrade

1. Tender evaluation experts cannot enter and exit automatically and require manual assistance.

The original access control system for fixed staff could not automatically identify the experts, resulting in the need for on-site staff to assist in opening doors and accessing the building, and the lack of automated and intelligent access control management.

2. Inability to record experts' trajectories.

Tender evaluation experts can move around the building at will, which is not conducive to the standard management of the tender evaluation site. Video surveillance has blind angles and cannot monitor the trajectory of the experts in real time, which is not conducive to later verification and tracing.

3. Experts entering the evaluation room by mistake.

Since the Public Resources Exchange has multiple evaluation rooms, there is a risk of experts entering the wrong evaluation room at the same time on the same day, which is not in line with the requirements of bid evaluation confidentiality measures.

4. Control areas not in place.

There are control areas with high confidentiality level requirements on site, but at present, only personnel can be arranged to be on site, and it is impossible to remind and alert in real time for illegal intrusion.
