Today there is an urgent need for effective monitoring whether for old buildings or new ones. While conventional early warning system for real-time monitoring is based on safety factor, this paper proposes a new reliability-based framework to monitor the safety of RC buildings probabilistically. The framework includes modeling resistance, predicting probability distribution of load effect, calculating reliability and setting reliability index threshold. The in-situ test data enables to update the resistance model through a Bayesian process. Meanwhile, the observed monitoring data predicts the probability distribution of load effect. FORM is used to calculate the reliability because the limit state function for real-time monitoring is linear and simple. This study shows that the reliability-based early warning system is of more scientific sense in quantifying the safety and may be applied to many engineering fields.

Motor listrik merupakan salah satu instrumen yang memegang peranan penting dalam mengendalikan pergerakan mesin-mesin produksi di Pabrik Kelapa Sawit (PKS). Pada PKS Sungai Bengkal Jambi, proses penggantian atau rekondisi sebuah motor listrik dengan daya 60 HP akibat overheat (terbakar) memerlukan waktu lebih dari 1 (satu) bulan. Untuk menanggulangi hal tersebut, dirancang suatu sistem kontrol tertutup yang terdiri dari sensor, indikator, kontroler, dan aktuator. Sistem dibuat dengan menggunakan sensor IC LM35 untuk mendeteksi temperatur bagian dalam motor listrik. Informasi temperatur dari sensor tersebut diterima dan diolah oleh mikrokontroler yang diprogram untuk merespon perubahan temperatur dan memberikan feedback dengan melakukan trip pada motor listrik saat temperatur operasi melebihi set point yang telah ditentukan. Setelah loop selesai, sistem akan mengaktifkan kembali motor listrik saat temperatur operasi sudah kembali normal. Feedback yang diberikan juga digunakan sebagai sistem peringatan dini (early warning system dengan menambahkan lampu indikator dan sirine pada sistem. Selain itu, mikrokontroler diprogram untuk mengkonversi perubahan temperatur dari sensor untuk diolah menjadi keluaran data digital. Semua data tersimpan dalam data logger (perekam data) dan ditampilkan secara langsung pada sevent segment display. Untuk menguji akurasi sistem, telah dilakukan pengambilan data temperatur sebanyak 30 kali melalui data logger. dan didapatkan nilai standar deviasi sebesar 0,77% dengan rentang sebesar 0,71 °C. Perbedaan hasil pengukuran jika dibandingkan dengan Termolaser adalah sebesar 0,013%.

Drinking water sources play an important role in assurance of life safety, normal production and social stability. In this paper, a real-time remote water quality monitoring and early warning system has been developed. The paper concentrates on the system architecture and key techniques of the real-time water quality monitoring and early warning. The implementation of the system by advanced water quality sensor techniques, wireless transmission, databases and water quality modeling is retraced in detail. It can be applied to the real-time remote monitoring of water quality and decision support for water pollution incidents.

Monitoring And Early Warning

In order to solve problems of the absence of security protection and the lack of early warning mechanism in the current elevator operation process, elevator safety monitoring and early warning system based on directional antenna transmission technology was proposed. The system includes sensor module circuit, microcontroller module circuit, display module, directional antenna transmission module, remote server and data monitoring system. Design ideas of hardware development, remote server and data monitoring system are introduced. Two version monitoring software are written, one for PC monitor, the other one for mobile phone monitoring. In order to improve data transmission distance, transmission rate and transmission quality, automatic antenna alignment system is designed, which combines the advantages of directional antennas and omnidirectional antennas transmission technique. To overcome problems such as instability of the alignment process, delay and other factors, DMC（ Dynamic Matrix Control ） algorithm should be used in the system and optimal control of the antenna angular alignment will be achieved. The system can continuously transmit real-time elevator’s working status information and environmental information, and it also send commands to notify elevator company managers once an abnormal conditions occur in the elevator, so that people can take urgent measures and maintenance measures. This system can be applied to real-time warning of all-types elevators.

Objective: This study focused on the application of wearable technology in the safety monitoring and early warning for subway construction workers. Methods: With the help of real-time video surveillance and RFID positioning which was applied in the construction has realized the real-time monitoring and early warning of on-site construction to a certain extent, but there are still some problems. Real-time video surveillance technology relies on monitoring equipment, while the location of the equipment is fixed, so it is difficult to meet the full coverage of the construction site. However, wearable technologies can solve this problem, they have outstanding performance in collecting workers’ information, especially physiological state data and positioning data. Meanwhile, wearable technology has no impact on work and is not subject to the inference of dynamic environment. Results and conclusion: The first time the system applied to subway construction was a great success. During the construction of the station, the number of occurrences of safety warnings was 43 times, but the number of occurrences of safety accidents was 0, which showed that the safety monitoring and early warning system played a significant role and worked out perfectly.
