Electronic school badges
Technical field
The utility model relates to significant nameplate technical field, especially a kind of novel electronic school badge.
Background technology
Traditional school badge is a kind of pure sign product by school gate Security Personnel identification of not charged sub-device.Along with development of electronic technology, all-in-one campus card is extensive use of, and for the campus information of managingization, has had unit to research and develop some and has had the Electronic school badges of Intelligent Recognition function in recent years.But existing product is because the volume of school badge itself is limit, and the mode of taking all is to be placed with a passive smart card in the inside of school badge.There is the defective of several aspects in this mode:
1, the school badge material there is considerable restraint, can only adopts plastics or resin one class material, can not use more robust metal material;
2, read distance closely, the student passes in and out the campus and is identified record if desired, school badge need be taken off on the specific card reader and be swiped the card.
Because above-mentioned defective, such Electronic school badges is received very big influence in application, can not promote on a large scale.
Summary of the invention
At the deficiency of above existing Electronic school badges, the purpose of this utility model provides a kind of novel electron school badge.
The purpose of this utility model is achieved by the following technical solution: a kind of Electronic school badges; it comprises attached plate on, attached plate and be arranged at attached plate and the following circuit substrate between the attached plate once, and this circuit substrate is provided with a battery, and is electrically connected battery-powered rf processing circuitry system with battery.
As the utility model optimized technical scheme, described circuit substrate also is provided with an antenna that is electrically connected with the rf processing circuitry system.
As the utility model optimized technical scheme, described rf processing circuitry system is a rf processing circuitry single-chip, be provided with the CPU(central processing unit of mutual information UNICOM in it, Central Processing Unit), Flash circuit and RF transmit-receive circuit, described antenna is connected with RF transmit-receive circuit.
As the utility model optimized technical scheme, the model of described RF transmit-receive circuit chip is nRF24LE1.
As the utility model optimized technical scheme, described rf processing circuitry system comprise information UNICOM by described battery powered discrete chip CPU, Flash circuit and RF transmit-receive circuit, described antenna is connected with RF transmit-receive circuit.
As the utility model optimized technical scheme, described battery is the high energy lithium-manganese cell.
With respect to prior art, the utility model school badge device utilizes the penetrability of microwave frequency band such as 2.45GHz frequency range, has improved the defective that the conditional electronic school badge can only use plastic material, can produce the school badge of more robust metal material; By built-in powered battery, initiatively send school badge ID number simultaneously, make transmission range farther, need not to take to make a return journey and initiatively swipe the card, make that the student more is ready to use; The utility model utilization carries battery powered remote proactive identification technology; decipherment distance can mate on a large scale according to the difference of receiver; can accomplish 0~20 meter reading range, can finish the school when therefore wearing this school badge easily and interrogate all-purpose cards application such as logical and the work attendance of student campus.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the modular structure synoptic diagram of first kind of embodiment of the present utility model.
Embodiment
As shown in Figure 1; this Electronic school badges comprises attached plate 10 on; attached once plate 20; be arranged at attached plate 10 on this and the circuit substrate 30 between the attached plate 20 down; this circuit substrate 30 is provided with a battery 31; one is electrically connected the rf processing circuitry system 32 by battery 31 power supplies with battery 31; this rf processing circuitry system 32 comprises the CPU(central processing unit; Central Processing Unit); Flash circuit and RF transmit-receive circuit and an antenna that is connected with RF transmit-receive circuit 33; wherein, CPU; equal information UNICOM between Flash circuit and the RF transmit-receive circuit three-circuit module.
Have specific computer software and identity id information in the Flash circuit, can control by CPU, regularly the identity ID that will be arranged on the Flash broadcasts away by RF transmit-receive circuit; External receiver is replied confirmation after receiving this identity ID; Electronic school badges can be closed a setting-up time section after receiving confirmation; in the period that this setting is closed, no longer send so that further reduce power consumption, setting-up time to after can restart the function of broadcast transmission again.
Described RF transmit-receive circuit is the single-chip nRF24LE1 of 2.45G radio-frequency receiving-transmitting.
Described battery 31 is the high energy lithium-manganese cell.
Described receiver installs as another, has set up into whole electronics campus system under the management of background computer software cooperates with Electronic school badges.
Described battery 31 makes Electronic school badges not rely on and external power source for Electronic school badges provides energy source, reaches the initiatively purpose of recognition.
The described shell of going up annex 10 and following annex 20 composition Electronic school badges; shell is as the housing of Electronic school badges; can provide parcel for the circuit part of Electronic school badges; and can print school's title in case surface; even further indicate student place class on the Electronic school badges surface; sex, information such as photograph.
Should be understood that application of the present utility model is not limited to above-mentioned giving an example, for those of ordinary skills, can be improved according to the above description or conversion that all these improvement and conversion all should belong to the protection domain of claims of the present invention.For example: in first kind of embodiment, described discrete device CPU, Flash, radio-frequency (RF) transceiver can be integrated into a single-chip, and the solution of single-chip can further reduce volume, reduces cost; It is described that the frequency of operation of Electronic school badges is not limited to preferred implementation, and it also can adopt other frequency ranges.
