At present, attendance recorder is as the support technology of Enterprises ' Modern management, and the people not only demand to it are very large, and also very high to the requirement of its function.Attendance recorder based on technology of Internet of things and mobile phone radio frequency technology will become the support of modern enterprise wisdom management important technology.In the popularization and application of Mobile phone one-card, domestic common carrier adopts the wireless short-distance communication solution based on SIM card, mainly contains at present " SIMPASS " and " RF-SIM " two kinds of technical schemes.General mobile phone attendance recorder is not supported RF_SIM and two kinds of radio-frequency cards of SIMPASS simultaneously, and this has brought inconvenience to the user.

Summary of the invention

Can only identify the relatively poor deficiency of radio-frequency card, practicality of a frequency range in order to overcome the radio-frequency (RF) identification attendance recorder, the invention provides a kind of mobile phone attendance recorder based on Internet of Things communication, this Internet of things mobile phone attendance recorder is supported RF_SIM and two kinds of radio-frequency cards, practical of SIMPASS simultaneously.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of Internet of Things attendance recorder, comprise microprocessor, double frequency card reading module, host computer, LCD liquid crystal display, keyboard, mass storage, power supply, real-time clock, hummer, wireless communication module and ARM11 module, described microprocessor is connected with double frequency card reading module, host computer, LCD liquid crystal display, keyboard, mass storage, power supply, real-time clock, hummer, wireless communication module and ARM11 module, pass through cdma network, one tunnel business information uploads to the business datum server, and another road machine information uploads to Internet of Things M2M platform.

As preferably, described microprocessor selects STM32F101, and described double frequency card reading module comprises induction antenna, 13.56MHz card reading module ZLG500S and 2.4G card reading module SHNM100 and SHNM201G; Described LCD liquid crystal display is used HT1621, and described large capacity reservoir selects AT24C256, and described real-time clock adopts DS1302.

The invention has the beneficial effects as follows:

(1) the present invention supports 13.56MHz to communicate by letter with the 3.4GHz dual-mode radio frequency.This attendance recorder reads when having realized mobile phone RFUIM and SIMPASS card, and the RFUIM card is the 2.4G communications band, and the SIMPASS card is the 13.56M frequency range.

(2) information of the present invention adopts two mechanism of sending out.The business information of this attendance recorder and machine information are by the cdma network transmission, and information adopts two mechanism of sending out.The business information that work attendance is relevant is transferred to the business datum server, the machine information of attendance recorder, and be included in line states, whether upgrade, online hours etc. then is transferred on the platform of internet of things.

Embodiment

The present invention will be further described below in conjunction with accompanying drawing.

With reference to Fig. 1 ~ Fig. 6, a kind of Internet of Things attendance recorder, described Internet of Things attendance recorder is comprised of EM equipment module such as microprocessor, double frequency card reading module, host computer, LCD liquid crystal display, keyboard, mass storage, power supply, real-time clock, hummer, wireless communication module, ARM11.Wherein two of the data of attendance recorder are machine-processed, and by cdma network, one tunnel business information uploads to the business datum server, and another road machine information uploads to Internet of Things M2M platform.

Fig. 2 is the interface circuit of STM32F101 of the present invention and double frequency card reading module.This module can be divided among the communication module SHNM201G(figure of 2.4GHz 22) and SHNM100(figure in 23), among the communication module ZLG500S(figure of 13.56MHz 24) and gauge tap (among the figure 25).By the 2.4GHz frequency range read head of wire jumper interface J6 selectively operating, disconnect and then select the SHNM201G read head, the SHNM100 read head is selected in short circuit.13.56MHz card reading module ZLG500S carries out serial data communication by pin RXD_TTL, TXD_TTL and microprocessor, by interface J3 link block antenna.Communication module SHNM201G and SHNM100 are 2.4G frequency range communication module, and with microprocessor PA9/USART1_TX, the PA10/USART1_RX port connects, and wire jumper interface J6 selects the real work module.
