Description
Technical field
The utility model relates to a kind of control device of seat heating, relates in particular to be used for the control device that automotive seat has switch, checks its duty.
Background technology
The opening and closing of automotive seat heating function are controlled by the seat heater switch, circuit connecting mode commonly used at present is that heater switch directly drives the seat heater strip, wherein there is the contact of two pairs of interlocks heater switch inside, when the pair of contact that connects the seat heater strip is connected, the contact that connects relay indicating light is also connected, thereby plays the effect of seat heating function indication.Though this mode is simple, it is in running order that the relay indicating light of seat heater switch just embodies heater switch, as the seat heater strip open circuit, circuit does not connect etc. when problem occurs, and does not see malfunction from heater switch.And under car load during X-ray inspection X, whether effective for detecting the seat heating function, can only when environment temperature is higher, cause very burden like this by checking whether seat heats up to work for inspection.
The utility model content
The technical problems to be solved in the utility model be realize a kind ofly can detecting heater strip automatically, whether line end exists fault.
To achieve these goals, the technical solution adopted in the utility model is: a kind of seat heating control apparatus, comprise control module, pilot lamp backlight, relay indicating light, microswitch and the heater strip formed by microprocessor and the driver that is connected with microprocessor and interface circuit, described pilot lamp backlight, relay indicating light, microswitch are connected with interface circuit respectively, and described heater strip is connected with driver.
Described driver is provided with short-circuit protection circuit.
Described driver is provided with the voltage reversal holding circuit.
Described driver is connected with two pins of microprocessor, is respectively microprocessor output signal pin and driver feedback signal pin.
Advantage of the present utility model is and can feeds back and be embodied on the relay indicating light the open circuit conditions of seat heating load; simultaneously load there is the effect of circuit protection; such device is convenient to detect; X-ray inspection X under the car load is facilitated; and the integrated degree of switch is higher; when the load of the many groups of increase, can on existing product, expand.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model instructions and the mark among the figure are made brief description:
Fig. 1 is the utility model circuit block diagram;
Mark among the above-mentioned figure is: 1, control module; 2, pilot lamp backlight; 3, relay indicating light; 4, microswitch; 5, driver; 6, heater strip; 7, interface circuit.
Embodiment
By a kind of seat heating control apparatus circuit block diagram shown in Figure 1 as can be known; this control device is by pilot lamp 2 backlight; relay indicating light 3; microswitch 4; driver 5; heater strip 6 and interface circuit 7 are formed; wherein driver 5; interface circuit 7 has connected and composed control module 1 with microprocessor respectively; interface circuit 7 be provided with three respectively with pilot lamp 2 backlight; relay indicating light 3 is connected with microswitch 4; pilot lamp 2 backlight is connected the switch of controlling pilot lamp 2 backlight and relay indicating light 3 with relay indicating light 3 with the pin of microprocessor through corresponding interface circuits 7; the positive pole of pilot lamp 2 backlight is received on the adjusting line 58b backlight; negative pole is controlled by microprocessor; microswitch 4 transmits the microprocessor switch controlling signal through the pin that corresponding interface circuits 7 is connected with microprocessor; heater strip 6 is connected with microprocessor through driver 5; driver 5 is provided with short-circuit protection circuit; voltage reversal holding circuit and to the diagnostic function of load cut-off; detect load circuit as driver 5 and be in off state; can give microprocessor by the feedback diagnostic signal; microprocessor is connected with two pins of driver 5, is respectively microprocessor output signal pin and driver 5 feedback signal pins.
The control principle of this device is:
After pressing microswitch 4, trigger pip is delivered to microprocessor after handling by interface circuit 7, and microprocessor judges this moment, whether the seat heating should be opening after receiving this instruction;
If heater strip 6 is not opened, then carry out next step operation, comprise that controlling pilot lamp 2 backlight through microprocessor extinguishes, light relay indicating light 3, drive 6 work of seat heater strip; Driver 5 detects load circuit and whether is in off state afterwards, will feed back diagnostic signal and pass to microprocessor; After microprocessor is received this signal, judge that load is the open circuit fault state, output is to the failure alarm signal of relay indicating light 3, and relay indicating light 3 is carried out the flicker order under the control of this signal, thereby embodies the indicating fault for load.
If heater strip 6 is opened, then press microswitch 4 once more, microprocessor executing state inverted command is promptly lighted pilot lamp 2 backlight, extinguishes relay indicating light 3, and discommect drive g, realizes the closing function to the seat heating.
