The base station comprises a UWB main control chip 1, a digital circuit module 2, a UWB radio frequency circuit module 3 and a UWB MIMO antenna 4, the UWB main control chip 1 is respectively connected with a CPU control unit 6 and a power module 7, the UWB radio frequency circuit module 3 is connected with the UWB main control chip 1 through the digital circuit module 2, the UWB radio frequency circuit module 3 is connected with the UWB MIMO antenna 4, and the UWB MIMO antenna 4 is used for being communicated with a positioning tag 5 signal.
When the UWB positioning technology is evaluated to be applied to a closestool, if environmental interference (a steel bar wall) is eliminated, the positioning error is required to be between 10cm and 15cm, and mass production is required, at least 2 base stations are required to be arranged on the closestool; if the toilet is a public toilet, only two base stations are needed to be used on one toilet, and only one base station needs to be installed on other toilets, so that the cost can be effectively saved.
The base station can be arranged on the toilet or around the toilet, the direction of the base station can be towards the toilet, interference can be eliminated, the efficiency of detection pairing can be improved, and the effectiveness of the angle of arrival can be properly set for male urine toilets in public toilets.
Taking two base stations as an example, the two base stations are respectively a base station R1 and a base station R2, the base stations are used for sending an activation signal when the positioning tag 5 enters the wake-up area, the positioning tag 5 is used for receiving the activation signal and then uninterruptedly sending a UWB pulse data frame, the base stations are used for receiving the UWB pulse data frame and transmitting information of the UWB pulse data frame to the CPU control unit 6, and the CPU control unit 6 is used for judging the spatial position of the positioning tag 5 according to the UWB pulse data frame and acquiring linear distances between the positioning tag 5 and the base stations R1 and R2 as d1 and d2, respectively.
Since common toilets include flip-top toilets, upright toilets and squat-bowl toilets, the following are described separately:
(1) the closestool is a flip closestool, and the base station can be arranged on the front side of a closestool water tank or the wall around the closestool. To further improve the system accuracy, the CPU control unit 6 also obtains the linear distance d3 of the positioning tag 5 from the center of the toilet bowl. When the minimum value of d1 and d2 is less than the distance L1 and d3 is less than the distance L, the CPU control unit 6 controls the toilet lid to be opened through the toilet control unit 8; when the positioning label 5 is far away from the toilet after the toilet lid is opened, and the minimum value of d1 and d2 is greater than the distance L2, the CPU control unit 6 controls the toilet to flush and close the toilet lid through the toilet control unit 8.
Referring to fig. 2, in the present embodiment, the distance L is selected to be 0.6m, the distance L1 is selected to be 2.5m, and the distance L2 is selected to be 2.5m, so that after the user carries the wearable positioning tag 5, such as a bracelet, into the effective radiation range of the base station, the toilet lid is opened when the minimum value of d1 and d2 is less than 2.5m, and d3 is less than 0.6 m. When the person leaves, the toilet cover is closed and the toilet flushing is opened when the minimum value of d1 and d2 is more than 2.5 m.
(2) The closestool is a standing closestool which can be arranged on the front side of a closestool water tank or on the wall around the closestool and is mainly used for male urination, so when the minimum value of d1 and d2 is smaller than the distance L3 and the positioning label 5 at least keeps still for a time T, the CPU control unit 6 controls the flushing of the closestool through the closestool control unit 8.
Referring to fig. 3, in the present embodiment, the distance L3 is selected to be 0.6m, the rest time T is selected to be 3 seconds, that is, after the user carries the wearable positioning tag 5, such as a bracelet, into the effective radiation range of the base station, when the minimum value of d1 and d2 is less than 1.2m, and the positioning tag 5 remains at rest for at least 3 seconds, the toilet starts to flush once.
(3) The toilet is a squat toilet, the base station can be arranged on the front side of a toilet water tank or on the wall around the toilet, and when the positioning label 5 is activated and is far away from the toilet, the minimum value of d1 and d2 is larger than the distance L4, the CPU control unit 6 controls the flushing of the toilet through the toilet control unit 8.
Referring to fig. 4, in the present embodiment, the distance L4 is selected to be 1.2m, that is, after the user enters the effective radiation range of the base station with the wearable positioning tag 5, such as a bracelet, the CPU control unit 6 controls the toilet flushing through the toilet control unit 8 when the minimum value of d1 and d2 is greater than 1.2m when the user leaves.
To further intelligentize the volume of water flushed by the toilet, the flush volume of the toilet is determined by the rest time of the location tag 5. When the relative rest time of the positioning tag 5 and the base station is more than or equal to the rest time T1 and less than the rest time T2, the flushing water quantity of the toilet is low; when the positioning tag 5 is kept at rest for a relative rest time with the base station of greater than or equal to rest time T2, the toilet flushing water volume is high. In this embodiment, the rest time T1 is selected to be 3 seconds, and the rest time T2 is selected to be 20 seconds.
In addition, the CPU control unit 6 is also connected with a manual control water tank flushing system and an electromagnetic water valve far infrared control flushing system 9. The manual control water tank flushing system and the electromagnetic water valve far infrared control flushing system 9 are used as the auxiliary of the system, and in practical application, the priority of the manual control water tank flushing system is higher than that of the system and is higher than that of the electromagnetic water valve far infrared control flushing system 9.
The power supply module 7 comprises the following three power supply modes of a base station, namely lamp control power supply, normal power supply or sound control power supply; in the lamp control power supply mode, the power supply module 7 is connected with the photosensitive element, and the photosensitive element triggers the power supply module 7 to supply power to the base station after detecting illumination; in the normal power supply mode, the power module 7 continuously supplies power to the base station; under the sound control power supply mode, the power supply module 7 is connected with the sound sensitive sensor, and after the sound sensitive sensor detects the sound wave, the power supply module 7 is triggered to supply power to the base station.
