Embodiment
As shown in Figure 1, the preset 1 of the electrical equipment that the utility model provides comprises control chip 11, interface 13, passes through the storer 12 that described interface 13 links to each other with the storer 21 of preset apparatus 2; Described storer 12 is used for the data message of the storer 21 of preset apparatus is backed up; Described control chip 1 is used to distribute the address information of the storer 12 of the storer 21 of described preset apparatus and described preset read-write equipment; Between the storer 21 of corresponding memory sending controling instruction, carry out data write then at described storer 12 and described preset apparatus.The steering order that described control chip 1 sends is for the address information of the storer at the data place of reading in advance, when storer is carried out read-write operation, and the data message that at every turn reads according to predefined numerical value from storer.
The utility model also comprises three switchgears, described switchgear one end is connected with ground, the other end is connected with three input ends of described control chip, when the operator presses control device, send the address information of corresponding memory to control chip, control chip is discerned the storer that this address information is judged needs operation, then to the corresponding memory sending controling instruction.Described switchgear comprises sense switch, write switch and reset switch, when described sense switch is pressed, send the address of the storer of connected equipment to control chip, when the said write switch is pressed, send the storage address of the preset apparatus of electrical equipment to control chip, when described reset switch is pressed, described control chip is resetted.Described control chip need carry out reset operation could carry out read-write operation to next preset apparatus.
The utility model also comprises at least one display device, and each display device is connected with a switchgear, shows the duty of the preset of described electrical equipment.
Fig. 2 is with the preset of the televisor circuit theory diagrams as specific embodiment.Preset apparatus is a televisor, by integrated circuit TMP87PS38N, E
2PROM--24LC08, crystal oscillator (8.000MHz) and parallel interface realize that TMP87PS38N is a control chip described in the utility model, mainly start to control making usefulness when work, and 24LC08 is a storer of the present utility model, and storage is by the E of televisor
2The data of reading among the PROM, crystal oscillator provides clock signal for TMP87PS38N.Preset apparatus connects with televisor by interface XZ901,5 volts of voltages that need when televisor provides work for preset.In use, by the specific program of TV CPU, make the CPU of TV itself and the storer E of TV
2PROM (D1 among the figure) disconnects connection, then by preset with on televisor is connected, TMP87PS38N can distribute an address for D1 automatically, TMP87PS38N also is address of storage block (D2 among the figure) distribution of preset inside simultaneously, TMP87PS38N is according to the instruction that receives then, read D2 by clock bus (SCL), data bus (SDL) control data by D1, or read D1 by D2, after operation is finished, instruction resets TMP87PS38N according to RESET, TMP87PS38N halt instruction operation.After each read-write operation is finished, will carry out reset operation to TMP87PS38N, TMP87PS38N just can carry out operation next time like this.
Fig. 3 is the circuit theory diagrams of described TMP87PS38N.It is that switchgear of the present utility model and operator communicate that TMP87PS38N touches button by three, when not operating, switchgear " RESET ", " WRITE KEY ", " READ KEY " remains high level, TMP87PS38N makes the input end " R/W OK " that is connected with switchgear simultaneously, " WRITING ", " READING " remains low level, and display device is by triode V902, V903, V904 and light emitting diode VD911, VD912, VD913 forms, and this moment, display device was not worked.When pressing the RESET key, TMP87PS38N resets to each pin, and the current potential of each pin is " 1 ", at this moment, triode V902, V903, the V904 conducting, pilot lamp VD911, VD912, VD913 also begin conducting, luminous.When pressing the READ key, it is electronegative potential that TMP87PS38N makes R/W OK pin, the square wave that READ pin output " 0 ", " 1 " replace, this moment pilot lamp VD911 by, flicker appears in VD913, after read operation is finished, R/WOK pin, READ pin output high level, VD911, VD913 conducting are luminous.Same principle, when pressing the WRITE key, VD911 flicker occurs by, VD912, after operation is finished, VD911, the VD912 conducting is luminous.
The course of work of described preset is: after preset is connected with TV, the disconnection that is connected of the control chip of TV and the control chip of TV own, the control chip of preset is connected with the E2PROM of TV, when the control chip of preset began to move, it sent instruction according to the instruction that reads or writes of receiving to E2PROM.Touch button and trigger the control chip action, when instruction when reading in, the control button sends TV inside E
2The address of PROM, when instruction for writing the E that time control button sends preset apparatus
2The address information of PROM, E
2PROM responds according to the information of receiving, control chip identifies E
2Behind the PROM, control chip is sent to E to the address information of the data message that reads in advance
2Among the PROM, then by E
2PROM sends the data message in the address realm, copies to the E of televisor through the random access memory of preset internal control chip
2Among the PROM.Because the random access memory capacity of control chip inside is limited, so the process of data read is carried out stage by stage, each read-write is a part of.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
