The Internet of Things is a small test in hotel hygiene supervision, and low-cost, high-reliability technology is “small and big” to open up a huge market

The trial implementation of the “Transparent Cleaning Intelligent Supervision System” in Xiacheng District of Hangzhou has opened up a new paradigm for hotel hygiene and health supervision. The Internet of Things technology enables the traditional hotel hygiene supervision to be improved, improving efficiency and increasing the happiness of hotel guests. feel.

Beep, beep… After a few seconds of continuous alarm sound, the hotel’s management staff quickly entered a guest room near the bar to correct and supervise the staff who were cleaning.

Beginning in December last year, in 12 hotels and 2 chain hotels in the Wulin Health Business District, Xiacheng District, Hangzhou, a “artifact” for hotel hygiene supervision, the “Transparent Cleaning Intelligent Supervision System”, was installed on a pilot basis. The Health Bureau and the hotel have realized the traceability of the whole process of hotel cleaning, completely solving the two major health supervision problems of “wiping everything with one cloth” and “not washing or changing guest items”.

At present, the system has monitored 66 disinfection rooms and 120 guest rooms online, and tracked 2,500 pieces of cotton fabrics. Using the Internet of Things technology, the passive housekeeping in the past is being rectified. Technology empowerment is expected to completely solve the problems of hygiene and safety in the accommodation, and truly make people traveling with peace of mind and sleep.

After the topic of #Hangzhouhotel bedding rags with chips# appeared on Weibo, many netizens also expressed their views on Weibo. The advanced nature of Hangzhou area is enviable, but more netizens hope that this set The system can be popularized all over the country, so that everyone can enjoy the “peace of mind” brought by the Internet of Things technology.

The first set of hotel health and health supervision system was launched, opening the curtain of hotel intelligence

A clean and hygienic living environment can not only make guests feel at ease, but also make people feel happy. In the past, when most of the guests stayed at the hotel, when they saw the windows and tables with clean windows, and touched the seemingly spotless bed and quilt, they would inevitably feel a little uneasy in their hearts, because they were worried that such clean cups and tidy mattresses would have anything to do with them. There was no thorough cleaning, and how exactly did the cleaning process go through.

Today, these troubles are all dispelled by the “transparent cleaning intelligent supervision system”.

In the hotel’s cupware washing room, a camera is recording and identifying the process of cleaning cups by staff in the washing room; the smart socket on the side is connected to the cupware disinfection cabinet, and the two smart devices are used to monitor the staff and the disinfection cabinet. Supervision of the working status and intelligent analysis of the data can comprehensively determine whether the cleaning and disinfection of the cups meet the standards.

In hotel rooms, cleaners need to wear a bracelet-type RFID (Radio Frequency Identification) reader for cleaning. To clean different places such as toilets and washstands, you need to use different rags to distinguish them. Each place that needs to be cleaned and each rag have a special pair of RFID tags that match each other. Once the rag is used incorrectly If there is a place, then the scene described above will appear, and the bracelet worn by the cleaner will sound a warning sound.

In addition, there is also a complete traceability process for the cleaning and disinfection of cotton fabrics in hotel rooms. Each cotton fabric in the hotel has built-in RFID tags with different numbers, and an RFID card reader is also installed at the handover site of the hotel’s delivery and cleaning. As a result, the time of sending and returning each piece of cotton fabric can be traced back. During the second inspection in the hotel, a handheld RFID card reader is used to scan the cotton fabric, and the relevant replacement information can also be obtained.

Not only that, this system forms a complete closed loop of hotel hygiene supervision, and all the obtained data will be uploaded to the background to form an information basis. Similarly, for the customers who stay in, these data are also made available to them in the form of “public announcement”. They only need to scan the QR code in the room with a mobile phone to obtain the corresponding room cleaning report. For example, whether the bed covers and pillow covers have been replaced and sent for washing, whether the cups are clean and disinfected, whether the toothbrush cups used for washing are disinfected, etc., the information is clear at a glance.

The trinity of device, pipe and cloud solves the two major pain points of guest room hygiene

Hotel hygiene has always been the focus of social attention, and news often broke the cleaning chaos in a certain hotel. Last year, a blogger named Hua Zong lost his golden hoop stick (“Hua Zong” for short) exposed 14 five-star hotels charging thousands of yuan a night in a row. Use dirty bath towels to wipe cups, sinks, mirrors and other hygienic messes. Moreover, Mr. Hua also bluntly said in an interview with a certain media, “Reality is worse than what the video shows.”

So in response to this, the “transparent cleaning intelligent supervision system” completely solves the two major pain points of hotel hygiene and cleaning: one is the mixed use of cleaning rags; the other is the replacement of guest items.

In the news introduction, the “Transparent Cleaning Intelligent Supervision System” consists of three modules, including intelligent monitoring of cups and washing rooms, radio frequency identification (RFID) cotton fabric circulation, and intelligent management of sanitary ware cleaning and disinfection. It can be seen that this system actually builds a closed loop of the three major links of “end-pipe-cloud”. Specifically:

Perception link – data collection: Through cameras, RFID tags and hand-held card readers, the data of the cleaning and disinfection process of cups in the washroom and the cleaning and disinfection process of available items in the guest room can be obtained, and then data collection can be realized;

Network transmission – data transmission: At this level, data reporting mainly relies on optical fibers and wireless networks, and the data is uploaded to the platform, which becomes the basis for decision-making by the management department;

Platform link – data processing: Through intelligent analysis of the data, it is possible to comprehensively determine whether the cleaning and disinfection meet the standards, and then form a decontamination report. If the cleaning and disinfection does not meet the standards, the system will push the warning information to various parties including hotel management and health supervision departments.

In general, this system integrates three types of technical products: data acquisition equipment, data transmission network and data integration platform, but in general, it is a mature technology, so it can also be quickly implemented and commercialized.

Universal end-to-end products have become the main reason for the implementation of the system, and the cost of a few dollars is not expensive

Compared with some high-level solutions, the products in the “Transparent Cleaning Intelligent Supervision System” have the advantages of cheap price, mature technology and easy promotion.

For example, the RFID tag used in it, Huang Wei, head of the Environmental Sanitation Supervision Section of the Xiacheng District Health Supervision Institute, said, “The cost of using chips and tags in cotton fabrics is not high, only a few dollars, and a hotel bed sheet is only a few dollars for a cleaning. Money, and the label can be washed at least 200 times, and the lifespan is about the same as the bedding itself.”

Huang Wei’s introduction is too succinct, but it is enough to see the maturity of RFID technology. As we all know, RFID has been used for decades. Specifically, its advantages are as follows:

A large amount of information storage, an RFID tag can store a large amount of information, including production, return date and other records, and can be rewritten and reused repeatedly. The read data can be uploaded and processed in real time to realize the traceability of the product;

The reading distance is long. According to the power of the RFID reader and the gain rate of the antenna, the reading distance can range from tens of centimeters to several meters;

Globally unique and non-reproducible, each RFID tag is unique, so it is like an “identity card”, which is bound to the item information for traceability in the flow of subsequent items;

Easy to store, RFID tags have the characteristics of waterproof, anti-magnetic, anti-corrosion, high temperature resistance, etc. Therefore, cotton fabrics with built-in RFID tags in hotel rooms will not suffer great losses during the cleaning process, and ordinary tags can even be stored for several years;

High security, one of the core technologies of RFID tags is the chip, and generally has a reliable security encryption mechanism inside to protect the security of data information;

It supports both batch reading and high-speed mobile recognition;

These characteristics of RFID technology almost all meet the needs of the complete set of solutions of “transparent cleaning intelligent supervision system”, whether it is cost, environmental preservation, data security and so on.

Of course, in addition to RFID, IoT technology has developed a variety of technologies for a large number of scenarios that require wide-area tracking and monitoring. Although it is not applied in the “transparent cleaning intelligent supervision system” solution, it also makes the IoT industry look at it. to more possibilities.

LoRa, Sigfox, and ZETA all have actions in the field of wide-area tags, such as LoRa Tag, which can be embedded in some positioning tracking devices. When an event is triggered, data upload is realized through the LoRa network, which can be used for asset tracking, drug tracking, etc. in application.

In addition, Sigfox also launched a cheap module called Admiral Ivory in September 2017. The price is only about 0.2 US dollars. The biggest feature of this module is that it can be used in a large number of disposable products. Completely discardable”. In the demonstration at the time, Sigfox embedded Admiral Ivory in a kraft paper envelope. When the envelope was opened, it would trigger the module to send a text message to the background and send it to the manager’s mobile phone in real time, which could track the location and location of the envelope in time. condition.

Domestically, Zongxing Technology and Guangxin Microelectronics launched the first ZETag cloud tag chip UM0068 for the Chinese market in March 2020. After that, Zongxing Technology and Socionext jointly launched the ZETag cloud tag SOC, which can be discarded after use. The ZEtag cloud tag has a lower price. The cost quotation is about 6.99 yuan, which is less than half of the cost of the LoRa Tag. In addition, a major feature of ZETag is that it is completely independently developed by Zongxing Technology, so there is no need to worry about the problem of technical “stuck neck”. .

New Paradigm of Smart Hotel Management, Ignite New Hope for Smart City

The trial implementation of the “Transparent Cleaning Intelligent Supervision System” has opened up a new paradigm for hotel hygiene and health supervision. The Internet of Things technology enables the improvement of traditional hotel hygiene supervision drawbacks, improving efficiency and increasing the happiness of hotel guests.

According to the “2020 China Hotel Industry Development Report” data, as of January 1, 2020, the total number of accommodation facilities in the country was 608,000, and the total size of guest rooms was 18.917 million. The promotion of the hotel health supervision system in the future still has a long way to go. However, this system is bound to inspire more IoT industry practitioners to have new thoughts on the construction of smart cities. Maybe the success of the hotel hygiene supervision case can be replicated in more industries.
