Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, this anti-theft system needs to be powered to it by an electric supply installation, anti-theft system is connected with complete machine control system by CAN, complete machine control system is a weak electricity system controlled integral device, its inside, not from charged pool, to be powered by anti-theft system output of powering completely under normal circumstances.This anti-theft system comprises CPU module, GPS module, GPRS module, electric power management circuit, accelerometer circuit.Include the I/O port be connected with each circuit, modules in CPU module, and complete machine master cock is connected to CPU module I/O port.Described CPU module is connected with described accelerometer circuit communication, described CPU module and described GPS module communicate to connect, described CPU module is connected with described GPRS module two way communication, and described GPRS module is connected with outside APP terminal communication, described CPU module and electric power management circuit are electrically connected, CPU module is connected by CAN chip with CAN, and CPU module and switch circuit are electrically connected.
If anti-theft system is removed or damages, then complete machine control system cannot normally work, querying command can be sent by CAN to anti-theft system after complete machine control system is energized at every turn, to verify whether anti-theft system normally works, if anti-theft system non-normal working, then complete machine control system can not receive the response message of the expection of being replied by anti-theft system.CAN is a kind of communication protocol, has very high reliability, is one of current most widely used fieldbus.In the present embodiment: electric supply installation can be the electric supply installation carried of Electrical Bicycle or automobile, what electric supply installation exported is the direct current (DC) of 8V-60V.
As shown in Figure 1, the voltage that electric supply installation exports, electric current is through input protection circuit, the mouth of input protection circuit is connected with the input end of switch circuit, the mouth of switch circuit is connected with the input end of mu balanced circuit, the mouth of mu balanced circuit is electrically connected with the energization input (i.e. the 5V power output end of this anti-theft system) of complete machine control system on the one hand, be electrically connected with the input end of lithium ion charge circuit on the other hand, the mouth of described lithium ion charge circuit is connected with lithium ion battery, lithium ion battery electric connection two-way with electric power management circuit on the one hand, whole anti-theft system is acted on the other hand by mu balanced circuit.
Described input protection circuit is for preventing the voltage of electric supply installation not in normal scope (8V-60V), if the input voltage of electric supply installation is too high, now cut off connects by input protection circuit, is not burnt to protect whole system.Switch circuit is for controlling unlatching or the cut out of externally fed circuit.
Described lithium ion charge circuit can charge to lithium ion battery, can prevent lithium ion battery from being exploded by overcharge or reducing service life simultaneously, thus realizes charging scientifically and rationally.
As shown in Figure 1, wherein, a mu balanced circuit is used for regulating the voltage of electric supply installation input, and use for lithium ion charge circuit and complete machine control system, this mu balanced circuit can provide for complete machine control system the 5V direct current (DC) regulated through voltage stabilizing; Another mu balanced circuit (it is a kind of low dropout voltage regulator) regulates the voltage that lithium ion battery exports, and produces 3.3V direct current (DC), use for anti-theft system.
Described electric power management circuit can detect the power supply state of lithium ion battery in real time, prevents lithium ion battery overdischarge, and signal is sent to outside APP terminal (APP terminal can be directly installed on the mobile phone of user) by GPRS module.
As shown in Figure 1, their location information, for locating the location status of Electrical Bicycle or automobile, is real-time transmitted to CPU module by described GPS module, and such CPU module can its location information of Real-Time Monitoring.In the present embodiment: GPS module has A-GPS function, A-GPS is on the basis receiving navigation satellite signal, the information (position of signal base station) of the communication operation base station at battery-driven car or electronlmobil place is also obtained by network, just can learn the position at battery-driven car or electronlmobil place fast, make location faster more accurate, user follows the trail of Electrical Bicycle or automobile continuously by the APP terminal of mobile phone.
Described accelerometer circuit is connected with accelerometer, accelerometer is arranged on anti-theft system PCB, when accelerometer detects Electrical Bicycle or automobile is extremely mobile, by accelerometer circuit, this abnormal signal is sent interruption to CPU module, CPU module processes these abnormal signals and judges, then report is sent by GPRS module APP terminal externally, the operations such as CPU module carries out networking control by instruction set to APP terminal, signal strength reads and restart.After APP terminal receives the mobile prompting of exception that GPRS module sends, user initiatively can open real-time navigation capability, if open, then this instruction is transferred to the GPRS module of anti-theft system by GPRS network, and by GPRS module transfer instruction to CPU module, now CPU module master cock circuit disconnects, and power supply voltage now will not had to export, so just cut off the power supply of complete machine control system.If accelerometer does not detect abnormal signal, now, anti-theft system is in dormant state.In other words, only have when accelerometer detects abnormal signal, APP terminal is transmitted a signal to by GPRS module, whether inquiry user initiatively opens position tracking function, now whole anti-theft system just can work, and under normal circumstances, anti-theft system is in dormant state, this has user to operate according to actual needs flexibly, also helps saving power consumption.
What deserves to be explained is, if anti-theft system is destroyed, then there will be following situation: 1, complete machine control system is without power supply source; 2, CAN reports an error; 3, complete machine master cock is invalid, and because complete machine master cock is not controlled by complete machine control system as in prior art, it opens control by anti-theft system, now, complete machine master cock will disconnect, and complete machine control system will not work, and can strengthen its theftproof performance.In other words, only have when complete machine control system judges that anti-theft system is normal work time, complete machine master cock is just opened.
In the present embodiment: be provided with pcb board and be embedded with antenna in GPS module and GPRS module, in manufacturing process, the width of demand fulfillment pcb board is greater than the width of antenna, the large I of antenna and pcb board size carry out reducing in proportion, after size reduces, the signal effect received can slightly reduce, but Strength Changes is little.Embedded antenna is non-disconnectable removing simultaneously, if the antenna generally can removed in employing prior art, positioning accurate accuracy may be caused to decline by malicious sabotage due to antenna, but adopt this non-disconnectable antenna that removes and pcb board, more hidden, want a destruction antenna and do not destroy whole anti-theft system, difficulty is larger, safer.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
