The liquid crystal display can visually display the used time, the NFC reading and writing mode can quickly realize timing setting and service time reading, the wrist strap is designed to be convenient to carry, and the sealing ring is designed to meet the waterproof requirement.)

1. A portable timer, which consists of a timer body (1) and a wrist strap (2) for carrying, wherein STN liquid crystal (7) is used for displaying hours and minutes for timing, and a button battery is arranged in a battery bin (3), and the portable timer is characterized in that: the USB port of the computer or the intelligent equipment is connected with the USB port (8) of the reader-writer (9), and the reader-writer (9) transmits data transmitted by the computer or the intelligent equipment through the NFC component (10); the timer (1) is in data communication with the reader-writer (9) through the NFC component (5) of the timer and displays timing by using the STN liquid crystal display unit; (4) a waterproof sealing ring of the battery compartment, and (6) a fastening screw of the battery compartment.

Technical Field

The invention relates to a novel timing, timing starting and controlling mode.A timer is free of an operation key and is in data communication with the timer by using a Near Field Communication (NFC) technology.

Background

There are generally two timing methods employed in places where time units are currently used as the calculation of the amount of consumption: one is to use a handwriting card to record the starting time, and the method needs manual participation in recording and recycling statistics, so that the efficiency is not high, the carrying is inconvenient for consumers, the risk of losing paper record sheets exists, and the consumer cannot conveniently check the consumed time in the using process; the other method is to record the starting time by using the existing intelligent device such as a mobile phone APP mode, which solves the efficiency problem of recording and statistics of the completion of consumption, but has consumption environment limitation, for example, waterproof consideration needs to be given to the mobile phone when the device is used in a place needing waterproof.

Disclosure of Invention

The invention aims to solve the technical problem of providing a mode which is friendly and efficient to consumers and merchants.

In order to solve the technical problems, the technical scheme of the invention is as follows: the timer and the reader-writer adopt NFC technology to communicate to finish data reading and writing, STN liquid crystal display is adopted as a display mode, and a common button battery is used as a power supply mode.

The technical characteristics of the invention are as follows: the wrist strap is designed, is convenient to carry, and can display the timing visually; the combination of NFC and STN can easily realize low power consumption of the whole product, and the whole product can work for a long time by using a common button battery; the waterproof design is easy to realize, and the waterproof design can be applied to occasions with waterproof requirements;

drawings

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings

Fig. 1 is a front and back view of the timepiece.

Fig. 2 is a reader/writer that sets a timer.

Detailed Description

The timer of fig. 1 is composed of a body 1, a watchband 2, a display unit 7, an NFC communication unit 5 and a battery compartment 3, wherein the battery compartment is provided with a waterproof ring 4, and the battery compartment is fastened by a bolt 6.

Fig. 2 is a schematic diagram of a reader/writer, and a main body 9 is composed of a USB connector 8 and an NFC reader/writer 10, and mainly completes a data reading/writing function of a timer.

When the computer timing device is used, the USB wire is connected with the computer and the reader-writer, the timer is arranged above the reader-writer, the computer writes required timing data into the timer and commands the timer to start working, or the data is read from the timer to finish the setting operation, and the user can perform timing work after the setting is finished.
