Description
Technical Field
The invention relates to the technical field of daily bathing and multi-floor bathing, in particular to a system and a method for identifying a bathhouse vacancy and optimizing a position recommendation.
Background
People take a bath before falling asleep every day, especially in the hot summer, after one day of sweat attack. However, due to the fact that population density is too high and spatial position is limited, in northern colleges and universities in China, bathrooms are often arranged on each floor, and therefore bathing service is provided for teachers and students more quickly and efficiently. And once the peak time of bathing at night is reached, students can hardly find a vacant position for bathing quickly, and the phenomenon of queuing in bathrooms is common. Each shower nozzle of each bathhouse can generate water flow with different temperature and different water quantity, and the suitable water temperature and the water pressure of each person are also different. How to find the optimal vacancy in the whole building in a short time is the problem to be solved by the application.
The existing idea is also available for position recognition, but the objects to which the position belongs are different from bathing, most of which are parking spaces, toilets, tables or chairs, and a method or a system for truly solving the problem does not exist.
Patent application No. 201480062042.6 discloses a vacancy management system and a vacancy management method. The invention has the following: a frame display unit that displays frames corresponding to a plurality of tables arranged in a store on a screen of the store terminal 2; a vacancy presence/absence changing unit that, when one frame is selected from the frames displayed on the screen, changes vacancy presence/absence information stored in the vacancy presence/absence information DB5b in association with the selected frame to content indicating that there is no vacancy; a vacancy situation updating unit that updates vacancy situation information indicating the degree of vacancy of the tables in the store, which is stored in the vacancy situation information DB5c, based on the vacancy presence/absence information; and a vacancy condition providing unit for providing vacancy condition information to the user terminal 3. The invention mainly provides and manages the real-time information of the vacancy in the shop, but the vacancy identification and the bathing vacancy identification have great difference and cannot be applied to the situation.
In the patent application No. 201610638742.6, a parking space indicating device is invented, the invention includes: the parking system comprises an inflatable structure and a parking space, wherein the inflatable structure is used for indicating whether a parking area is occupied or not, and a solar power generation film is coated on the outer surface of the inflatable structure; the solar power generation film is connected with the power storage device, and the power storage device receives electric energy generated by the solar power generation film. According to the parking space indicating device and method provided by the embodiment of the invention, the vacant parking spaces are indicated through the inflatable structure, the solar power generation film is coated on the surface of the inflatable structure, and the generated electric energy supplies power for the vehicles in the parking spaces, so that the vacant parking space indicating function, the automatic power generation function and the power supply function of the parking lot are realized, the intelligent level of the parking lot is improved, the defects of high cost and single function of the conventional parking space indicating mode are overcome, and the solar power generation makes a contribution to the energy shortage problem. However, the vacancy indication is not suitable for reminding of a bath vacancy, and the functions of generating, charging and the like are not consistent with the bath problem.
In the patent with the application number of 201720161751.0, the invention provides a bathhouse use condition display system for colleges and universities, which comprises a first pedal arranged below a shower head and a second pedal arranged in a waiting area, wherein the first pedal and the second pedal respectively comprise an upper pressing plate and a lower pressing plate, a spring is arranged between the upper pressing plate and the lower pressing block, two metal sheets are arranged on the lower pressing block, and a conductive metal block is arranged on the bottom surface of the lower pressing block: a detection circuit is connected between the two metal sheets and comprises a protection resistor, a signal emitter and a power supply which are connected in series; the invention provides a colleges and universities bathhouse use condition display system, which can be used by students to know the use condition in a bathhouse in real time, so that the students are prevented from blindly waiting in the bathhouse and wasting a large amount of time. Meanwhile, students can be effectively prevented from entering a bathing room in a piled state to cause congestion of the bathing room, and safety accidents such as treading and the like are avoided. However, the invention is not connected to the intelligent terminal, the display mode is displayed by a group of LED lamps, the information sharing performance is lacked, and the system does not detect the technologies of flow, water temperature and the like, so that the consideration of safety and comfort factors of student groups is lacked.
