Embodiment
As shown in Figure 1, wireless measurement device of the present utility model constitutes: measure jig and be connected with the data transmit-receive circuit, the data transmit-receive circuit comprises data encoding circuit, data transmission circuit, data receiver circuit, data decode circuitry, central processing element and indicating meter, data encoding circuit connection data transmission circuit, data receiver circuit connection data decoder circuit, data decode circuitry is connected with central processing element, and central processing element connects indicating meter.Described anode measure jig by the anode jig, be provided with spring at the anode jig and consist of, the anode jig is provided with voltage acquisition point and transmission circuit, as shown in Figure 2.Measure every anode rod of jig and be equipped with 1 pair.
As shown in Figure 3, the wireless signal coding LX2262 unicircuit of encoding transmitting circuit is finished, and this circuit has 8 bit address signals and 4 bit data signals.Definition A7 is chip selection signal, if A7 is low level, then receiving circuit does not receive all data of this circuit, and A6 is that 1 what select is that the anode of A face is measured, and A5 is that 1 what select is that the anode of B face is measured, and A0～A4 is the anode address, and monolateral maximum can measure 2
5-1=31 root anode can be measured 62 anodes altogether, can satisfy the now anode measurement of domestic all aluminium cells fully; Data adopt the ASK mode to the modulation system of high frequency carrier, both when the signal that sends data is 1, connect the high-frequency oscillator power supply, send high-frequency wireless signals.When the transmission data were 0, deenergization quit work, circuit working current when static state is almost nil, the power supply VCC of LX2262 is in normally off, and the voltage that normally records at anode rod is no more than 5mv, and the data terminal of LX2262 can be accepted this data.In case the LX2262 chip operation then can send the data that gathered by D0～D3.When reality is used, because magnitude of voltage is less than normal, select voltage directly to receive D1 and D0, allow the GND of D2 and D3 connection circuit plate.
As shown in Figure 4, what the wireless receiving of data decode and receiving circuit and modulating part adopted is ready-made high frequency receiver module, can simplified design work, and reliability is better, what receiver module adopted is superregenrative reception, and concrete demodulating process is: when projector transmission A7 is 1, launch accordingly high frequency circuit work, receiving unit will correspondingly receive the high-frequency signal of a 315M, makes module be output as 1.When projector transmission A7 was 0, the emission HFS quit work, and receiving unit is output as 0, has so just realized the transmission of wireless signal.Receive and the serial signal of demodulation signal out after being coding unicircuit LX2262 coding through high frequency, must just can restore the control signal data through corresponding decoder circuit decoding.LX2272 has just taken on this decoding task.LX2262 and LX2272 are the coding and decoding unicircuit of a pair of special use, when 8 bit address data of the 8 bit address data of receiving unit LX2272 and radiating portion are identical, will be at high level of 17 pin output of LX2272, the expression successfully decoded, simultaneously at the corresponding data signal of 4 bit data positions output, the data bit that follow-up output control circuit is just exported according to decoding, trip switch.
As shown in Figure 5, in the use of display circuit chip, be chosen in loading respective anode label and launch by wireless launcher; Concentrating the set of frequency of receiving device is that launching device is consistent, in time accept related data packets, after the parsing, corresponding anode voltage value is processed, and numerical information shown at liquid crystal display, indicate with distinct colors for reaching unusual magnitude of voltage, remind the electrolysis procedure personnel that corresponding anode is detected, adjusts.
