Referring to fig. 1, the present embodiment provides a method for detecting an erase head, which includes the following steps:
s1: controlling the heating plate to heat the erasing head;
s2: acquiring a signal which is output by a temperature sensor and represents the temperature of an erasing head;
s3: after the erasing head is heated by the heating sheet for a first preset time, if the temperature is equal to or higher than a first preset temperature, outputting a first control signal; and if the temperature is lower than the first preset temperature, outputting a second control signal.
The working principle of the erasing head detection method is as follows:
the erasing head detection method comprises the following steps: controlling the heating plate to heat the erasing head; acquiring a signal which is output by a temperature sensor and represents the temperature of an erasing head; after the erasing head is heated by the heating sheet for a first preset time, if the temperature is equal to or higher than a first preset temperature, outputting a first control signal; and if the temperature is lower than the first preset temperature, outputting a second control signal.
Therefore, the erasing head detection method can output different control signals according to different temperatures by monitoring the working temperature of the erasing head in real time, and further feed back the real-time working state of the erasing head in real time, so that the erasing head can be repaired in time when the erasing head fails, and the normal work of the printer is ensured.
It should be noted that, in this embodiment, the first preset temperature refers to a temperature when the printer is in a standby state; when detecting the working temperature of the erasing head, the working temperature of the erasing head can be distinguished according to different working states of the printer, that is, when the erasing head is heated by the heating plate, the erasing head needs to be heated to different temperatures according to different working states of the printer, and therefore, in other embodiments of the present invention, when the first preset temperature is set, the first preset temperature may be a temperature when the erasing head is in a standby state, or may be a temperature when the ribbon is erased.
In addition, in this embodiment, after acquiring the actual temperature of the erasing head, the operating state of the erasing head can be fed back to the user by outputting the first control signal and the second control signal, and in this process, the state of the erasing head is determined according to the comparison between the normal temperature at different stages and the time operating temperature of the erasing head, and since the first preset temperature refers to the temperature of the printer in the standby state, when the actual temperature of the erasing head is equal to the first preset temperature, it is indicated that the operating state of the erasing head is normal, and at this time, the printer is in the normal standby state; when the actual temperature of the erasing head is lower than the first preset temperature, the working state of the erasing head is abnormal, and the erasing head needs to be overhauled at the moment;
in order to facilitate the user to know whether the erasing head is in the normal state or the abnormal state, in this embodiment, an indicator light is provided for feedback to the user; specifically, the indicator light is in a green normally-on state after receiving the first control signal; and the indicator lamp is in a red flashing state after receiving the second control signal. It should be noted that, in other embodiments of the present invention, in order to make the user know that the erasing head is in the normal state or the abnormal state, other types of structures or devices may be used to provide feedback to the user, for example, a display screen or an alarm may be provided.
Further, in this embodiment, after the step of outputting the first control signal if the temperature is equal to the first preset temperature, the method for detecting an erase head further includes:
controlling the heating sheet to heat the erasing head;

wherein the first preset temperature is lower than the second preset temperature.
That is, when the printer in the standby state performs printing, the erasing head needs to be heated, so that the temperature of the erasing head reaches a second preset temperature; in the heating process, the temperature of the erasing head needs to reach a second preset temperature, and at the moment, whether the temperature of the erasing head reaches the second preset temperature needs to be judged, so that if the temperature of the erasing head is equal to the second preset temperature after the erasing head is heated by the heating plate for a second preset time, the printed ribbon starts to be erased; if the temperature of the erasing head is lower than the second preset temperature after the erasing head is heated by the heating sheet for the second preset time, a third control signal is output, and the indicator light is in a red flashing state after receiving the third control signal.
Further, in this embodiment, after the erasing head is heated by the heating sheet for the first preset time or the second preset time, if the temperature is greater than the third preset temperature, the fourth control signal is output; if the temperature is lower than the fourth preset temperature, outputting a fifth control signal; if the temperature of the erasing head is higher than the third preset temperature in the process of being heated by the heating sheet, outputting a fourth control signal; if the temperature is lower than the fourth preset temperature, outputting a fifth control signal; the second preset temperature is less than the third preset temperature, and the fourth preset temperature is less than the first preset temperature.
Further, in this embodiment, the first preset temperature is less than the second preset temperature, the second preset temperature is less than the third preset temperature, and the fourth preset temperature is less than the first preset temperature; the first preset temperature is 65 ℃, the second preset temperature is 85 ℃, the third preset temperature is 135 ℃ and the fourth preset temperature is 35 ℃. The first preset time is equal to the second preset time, and the first preset time and the second preset time are both 1min.
Based on the content, the invention also provides a printer, which adopts the erasing head detection method to detect the erasing head of the printer, wherein the printer comprises a controller, a temperature sensor, an erasing head and an indicator light, and the indicator light and the temperature sensor are communicated with the controller;
the temperature sensor is used for detecting the temperature of the erasing head and outputting a signal representing the temperature of the erasing head;
the controller is used for controlling the heating sheet to heat the erasing head and acquiring a signal which is output by the temperature sensor and represents the temperature of the erasing head; after the erasing head is heated by the heating sheet for a first preset time, if the temperature is equal to or greater than a first preset temperature, outputting a first control signal; if the temperature is lower than the first preset temperature, outputting a second control signal;
the indicator light is used for being in a green normally-on state under the condition of receiving the first control signal; and the second control signal is used for being in a red flashing state under the condition of receiving the second control signal.
Further, in this embodiment, the controller is further configured to control the heating sheet to heat the erasing head after the erasing head is heated by the heating sheet for a first preset time and after the step of outputting the first control signal if the temperature is equal to or greater than the first preset temperature; if the temperature of the erasing head is equal to or greater than the second preset temperature after the erasing head is heated by the heating sheet for the second preset time, controlling the erasing head to erase the ribbon; if the temperature of the erasing head is lower than the second preset temperature after the erasing head is heated by the heating sheet for the second preset time, outputting a third control signal; wherein the first preset temperature is lower than the second preset temperature;
the indicator light is also used for being in a red flashing state under the condition that the third control signal is received.
Further, in this embodiment, the controller is further configured to output a fourth control signal if the temperature is greater than a third preset temperature after the erasing head is heated by the heating sheet for a first preset time or a second preset time; if the temperature is lower than the fourth preset temperature, outputting a fifth control signal; the second preset temperature is lower than the third preset temperature, and the fourth preset temperature is lower than the first preset temperature;
the indicator light is in a red flashing state under the condition that the fourth control signal is received; and the controller is used for presenting a red flashing state under the condition of receiving the fifth control signal.
In summary, in the embodiment, in the process of detecting the temperature of the erasing head by the printer, since the temperatures of the erasing head required in different operating states of the printer are different, the controller is required to determine the temperature of the erasing head according to the operating state of the printer;
specifically, when the printer is in a standby state, the controller is required to judge whether the temperature of the erasing head is equal to a first preset temperature; if the temperature of the erasing head is lower than the first preset temperature, the controller is required to judge whether the temperature of the erasing head is lower than a fourth preset temperature; when the temperature of the erasing head is lower than the first preset temperature and the fourth preset temperature, the indicating lamp receives the second control signal and the fifth control signal and is in a red light flashing state; when only one of the second control signal and the fifth control signal is received, the controller can set the flicker frequency and the flicker frequency, so as to distinguish different abnormal conditions.
Similarly, when the printer is in a working state, the controller is required to judge whether the temperature of the erasing head is equal to a second preset temperature; if the temperature of the erasing head is lower than the second preset temperature, the controller is also required to judge whether the temperature of the erasing head is lower than a fourth preset temperature; because the indicator light can receive the third control signal and the fifth control signal and is in a red light flashing state when the temperature of the erasing head is lower than the second preset temperature and the fourth preset temperature; when only one of the third control signal and the fifth control signal is received, the frequency of the flicker and the number of the flicker can be set, so as to distinguish different abnormal situations.
In addition, in the process of heating the erasing head by controlling the heating sheet through the controller, the heating effect of the erasing head also needs to be monitored, therefore, the controller is required to judge the heating effect according to the actual temperature of the erasing head, if the erasing head is heated by the heating sheet for a first preset time or a second preset time, the temperature of the erasing head is greater than a third preset temperature, and the controller outputs a fourth control signal; if the temperature of the erasing head is lower than the fourth preset temperature after the erasing head is heated by the heating sheet for the first preset time or the second preset time, the controller outputs a fifth control signal.
When the indicator light is used for feedback, and the indicator light is in a red flashing state when the indicator light receives the second control signal, the third control signal, the fourth control signal and the fifth control signal, so that the received signals are distinguished by setting the flashing frequency and the flashing times.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
