As optimization, said single-chip microcomputer also is connected with warning circuit.
As optimization, show magnitude of voltage on the said LCD display and show electric weight, and show the residue running time through the ladder graphics mode.
Beneficial effect: simple, the integrated degree of hardware configuration of the present invention is high, convenient for installation and maintenance, has practiced thrift hardware cost, and can use pictograph on display screen, to show the electric weight situation in real time.
Description of drawings
Fig. 1 is a circuit structure block diagram of the present invention.
Fig. 2 is a software flow block diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further:
As shown in Figure 1, intelligent sweeper electric quantity display device comprises single-chip microcomputer, direct supply, voltage sample circuit; Wave filter, switching power supply, 232 interfaces; Data-carrier store and LCD display, direct supply are connected with voltage sample circuit with wave filter respectively, and wave filter also is connected with switching power supply; Switching power supply also is connected with the input end of single-chip microcomputer with voltage sample circuit, and single-chip microcomputer also is connected with 232 interfaces, data-carrier store and LCD display, and 232 interfaces also are connected with the host computer computer; Wherein direct supply is the 36-48V accumulator, and single-chip microcomputer also can be connected with warning circuit, when cell voltage is not enough, can carry out alarm; Show magnitude of voltage on the LCD display and show electric weight, and show the residue running time, can also show current date, time etc. through the ladder graphics mode.
Software flow block diagram as shown in Figure 2; At first voltage sample circuit carries out the AD conversion with detected battery tension; Signal after the conversion carries out binary-coded decimal conversion through single-chip microcomputer again, if the magnitude of voltage after the conversion greater than 42V, full lattice display voltage value of display and figure; If be less than or equal to 33V then display voltage value, undertension and figure, also can carry out alarm simultaneously less than 33V if whether magnitude of voltage is seen less than 42V again; If magnitude of voltage is between 33V and 42V, then display voltage value and figure.
