What should pay attention to the purchase of electric tourist and sightseeing vehicles?
Domestic famous tourist attractions will receive tens of thousands of tourists every year. In order to provide tourists with better services, electric tourist sightseeing vehicles are an indispensable excursion tool. When choosing an electric tourist and sightseeing vehicle, we not only need to look at the number of people it carries, but also whether or not its appearance is beautiful and beautiful. There are still some issues that need our attention, take a look at the specific introduction.
First, from the perspective of the system configuration of the vehicle. Judging from the electric tourist car circuit system, these types of circuit configurations are commonly used in such vehicles: DC series excitation systems, brushless DC systems, and AC asynchronous systems. These methods are to ensure the stable operation of the sightseeing car. The DC series excitation system is a relatively traditional method. Once the system has a problem, the maintenance cost is relatively high. Many new tourist vehicles currently do not use this method. . The brushless DC system is a widely used method at present. Its advantage lies in its strong endurance, no maintenance, high efficiency, good vehicle speed adjustment, and overall vehicle safety. Higher, so it is widely used. The technical level of AC asynchronous systems in China is not very mature, so it is not widely used, but there are good prospects for development in the future.
Second, from the perspective of the adaptability of vehicles. Electric tourist vehicles are used in different scenic spots and attractions. Adaptability to the road conditions is a problem that we should value when choosing vehicles. Because of the flatness inside the amusement park and in the city, the vehicle can maintain a stable turntable. If it is in a natural scenic spot such as a mountainous area, the road surface is slightly rugged, requiring good adaptability of the vehicle. Under special road conditions, the vehicle must have good starting ability, have good climbing ability during driving, and must have enough impact on passengers when it encounters special circumstances. The adaptability of electric tourist and sightseeing vehicles to road conditions is more important and directly related to the ride experience of tourists.
Third, from the perspective of models. In terms of model selection, we mainly consider the problem of the number of seats. There are currently six, eight, and twelve seat models. It is not the choice of more seats. Instead, according to the actual situation, choose a sightseeing car with good safety, good-looking appearance and scenic style.
Introduction
Holter ECG Monitoring Systems adopt 12-lead system of international standard, which can continuously record ECG waveform for 24-hour and analyze ECG waveform by the PC software. It is applicable for use in medical institution and community.
Analysis Software Function
1.The rate of checking RR wave up to 99.9%, which increased the accuracy of analysis without losing wave.
2.AI histogram function which can directly distinguish various abnormal ECG which can analyze faster.
3. Dynamic ECG [Channel Correct" function, which can correct mistakenly wearing that makes the analysis more accurate.
4.Lorenz and Demix analysis function, which can analyze more faster, more accurately. Single medical case can be completely analyzed in 10 min, which can reduce the physician`s work.
5.ST can be displayed in many kinds of form, which ensures that analyzing ST- Trends Diagram comprehensively, observing the whole or partial ST variety to analyze the specific area of myocardial ischemia.
6.Atrial fibrillation function can be recognized automatically and can distinguish atrial fibrillation case, give advice and generate analysis report .
7.Unique Cardiac Fatigue Index function, which can judge index of Cardiac Fatigue .High-risk groups can be found and early intervention treatment can be taken by the index, which can effectively judge the heart age and predict SCD (Sudden Cardiac Death).
8. P-wave analysis function, which can check cardiac arrhythmia (such as AVB).
9.According to the requirement of patients, options can be selected freely while printing report, which can save physician `s time
10. ECG can be printed by various forms according to the user`s requirement.
11.Pacemaker analysis function, which can analyze different pacemakers(such as AAI,VVI,DDD).
12.The comprehensive analysis system of stand-alone version with network version ,users can freely select any model.
13.Wire and wireless simultaneously transfer mode ,which reduce complicated performance.
14. Dynamic ECG and static ECG analysis system ,which reduced complex operations.
15. Time Domain and Frequency Domain function on HRV module can reflect the moderation effect of sympathetic and parasympathetic to the heart rate.
16.HRT function can predict myocardial infarction which has clinical value.
17.ST function which can check the exact time and length of myocardial ischemia in 24 hours.
