The specific embodiment
Below in conjunction with embodiments of the invention of accompanying drawing narration
The device of present embodiment, host and slave processors all adopt the MSP430 single-chip microcomputer as primary processor, and this microcontroller is a series of 16 super low power consuming single chip processors that TI company releases,
As shown in Figure 1, the placement location of two main frames: one (main frame one) is placed on runway starting point place, and another (main frame two) is placed on the runway destination county.50 slaves are competed on one's body the runner wears by 50 respectively:
1. when the tester comes the runway starting point, open the slave switch; Main frame one sends the counting number of turns (this numerical value is unit with 0.5) to all slaves, and slave is received the number of turns and is presented on the liquid crystal display.
2. block clearance time, main frame sends timing instruction to all slaves, and slave picks up counting after receiving this instruction; 3. in the running process, as tester during alternately through main frame one, two, every through main frame once, the number of turns can correspondingly subtract 0.5 circle.
4. when the number of turns was kept to zero, timing stopped, and will show tester's testing time (promptly running the used time of the above-mentioned number of turns) this moment on the liquid crystal display.
Main frame adopts MSP430F149, shown in the block diagram of the following Fig. 2 of its hardware.Adopt the power supply of 3.7V Li-Ion rechargeable battery, give the power supply of MSP430F149 single-chip microcomputer to 3.3V, after booster circuit boosts to 5V, give wireless transmitter module and lattice lcd power supply through the mu balanced circuit voltage stabilizing; Lattice lcd adopts homemade TOPWAY3033 liquid crystal, and display resolution is 128*64, and this liquid crystal carries Hanzi font library, and its 8 data lines links to each other with single-chip microcomputer P2 mouth, and 3 control lines are connected with P3.0～P3.2 mouth respectively; Eight key boards are connected with the P1 mouth of single-chip microcomputer, finish the input function of data, instruction, and wireless module is connected with the hardware serial port circuit of single-chip microcomputer, and realization information is sent to the single-chip microcomputer of slave by serial ports.Main frame two places have removed liquid crystal display and keyboard in order to reduce cost, replacement with indicator lamp, represent that when indicator lamp glimmers main frame two is working properly, when indicator lamp goes out, expression main frame two operation irregularities or do not work.
Slave adopts MSP430FE425, and its hardware is shown in the block diagram of Fig. 3.Slave adopts the power supply of 3.7V Li-Ion rechargeable battery, gives MSP430FE425 single-chip microcomputer and wireless receiving module power supply through the mu balanced circuit voltage stabilizing to 3.3V, and display module adopts 7 half segmentation liquid crystal, satisfies data fully and shows needs.Wireless module links to each other with the hardware serial port circuit of 430 single-chip microcomputers, realizes that the data that will receive are sent to single-chip microcomputer.This slave, volume is little, low in energy consumption, and is in light weight, makes things convenient for the tester to carry, simultaneously this system have the accuracy of timekeeping height, in time convenient, economize characteristics such as the people is laborsaving.Be applicable to fitness examination and measurement.
Fig. 4, Fig. 5, Fig. 6 have shown the process that the host and slave processors information of present embodiment is transmitted
After the main frame initialization, the prompting input timing number of turns on liquid crystal display after the number of turns that will run with the keyboard input, is pressed acknowledgement key then.Main frame begins to send the counting number of turns to slave, and after the tester received the number of turns, the staff pressed off button in the time of off, and this moment, main frame sent the timing instruction.Send a specific character then, until this EOT always.
After the slave initialization, prepare to receive the timing number of turns, when receiving the timing number of turns, on liquid crystal display, show the information of the number of turns.After slave received the timing instruction, slave picked up counting and the timing situation is shown on liquid crystal display, when slave receives the signal of main frame one transmission, with a mark position 1, when slave is received the signal of main frame two transmissions, with above-mentioned flag bit zero setting; When slave is received the signal of any main frame transmission, judge it is main frame one or main frame two earlier, whether the main frame that judgement subsequently and last sends signal is identical, and as if different, then the number of turns reduces by half, if difference, then the number of turns keeps; Whether be zero, if non-vanishing, then continue counting if detecting the number of turns subsequently, if zero counting stops.
