step S101, temperature data of the engine is acquired.
In the present embodiment, the temperature data of the engine of the construction machine 10 is obtained by detecting the temperature of the coolant of the engine by a temperature sensor.
Therefore, referring to fig. 3, step S101 may include sub-step S1011:
and receiving temperature data sent by a temperature sensor for detecting the temperature of the cooling liquid of the engine.
In other embodiments, the temperature data may also be obtained by detecting the temperature of other relevant objects that affect the starting of the engine, such as the ambient temperature of the engine.
Further, with reference to fig. 2, the steps of the starting motor protection method further include:
and step S102, acquiring single allowable operation time, minimum interval time and actual operation times of a starting motor of the engine according to the temperature data.
After receiving temperature data sent by a temperature sensor for detecting the temperature of the coolant of the engine, the single allowable operation time, the minimum interval time and the actual operation times of the starting motor of the engine of the construction machine 10 are acquired according to the temperature data. The single allowable running time, the minimum interval time and the actual running times correspond to each other, which shows that the starting times of the starting motor are required under the temperature data, the safe running time of the starting motor after each starting is ensured under the temperature data and the starting times, and the safe interval time between two running times, so as to ensure that the starting motor is not burnt.
As the temperature data increases, the single-shot allowed run time decreases and the minimum interval time increases. That is, in general, the higher the temperature of the engine coolant, the shorter the single-time permitted operation time of the starter motor, and the longer the minimum interval time.
Referring to fig. 4, step S102 may include sub-step S1021:
and acquiring a preset data group corresponding to the temperature data in a plurality of preset data groups of a preset database, wherein each preset data group comprises single allowable operation time, minimum interval time and actual operation times which are matched.
In practical applications, a preset database may be set at a production stage, and a plurality of preset data sets are stored in the preset database, where each preset data set includes a set of single allowable operation time, a set of minimum interval time, and a set of actual operation times, which correspond to each other. Each preset data set is correspondingly preset with a comparison value or a comparison interval, after the temperature data are obtained, the temperature data are compared with a plurality of comparison values or a plurality of comparison intervals, the comparison value or the comparison interval corresponding to the temperature data are obtained, and then the corresponding preset data set is obtained.
Further, with reference to fig. 2, the steps of the starting motor protection method further include:
and step S103, adjusting the load of the engine to a preset state.
Since the engine load of the construction machine 10 may also affect the normal start of the engine, in order to avoid the burning of the starting motor due to the excessive engine load, the engine load is adjusted to the minimum preset state before step S104. For example, in practice, the hydraulic pump connected to the engine output may be regulated.
Further, with reference to fig. 2, the steps of the starting motor protection method further include:
and step S104, controlling the actual running times of the starting motor, controlling the single allowable running time of each actual running of the starting motor, and controlling the minimum interval time between two adjacent running times.

and sequentially and alternately sending a preset number of starting signals and stopping signals to the starting motor, wherein the stopping signals and the previous starting signals are separated by single-time allowed running time, and the stopping signals and the subsequent starting signals are separated by minimum separation time, and the preset number is the same as the actual running times.
The starting motor protection method provided by the embodiment is used for controlling the starting motor of the engine, so that the starting motor can adapt to various starting temperature environments, the actual starting running times, the single allowable running time and the minimum interval time of the starting motor are obtained according to the temperature of the cooling liquid of the engine, and the starting motor is prevented from being burnt due to overlong running time, or overlong running times, or overlong interval time. Meanwhile, the protection method for the starting motor provided by the embodiment also limits the load of the engine before the starting motor is started, and prevents the starting motor from being burnt due to overlarge load of the engine.

And the comparison module 220 is used for acquiring the single allowable operation time, the minimum interval time and the actual operation times of the starting motor of the engine according to the temperature data.
The comparison module 220 is electrically connected with the receiving module 210, the receiving module 210 transmits the temperature data sent by the temperature sensor to the comparison module 220 after receiving the temperature data, and the comparison module 220 obtains the single allowable operation time, the minimum interval time and the actual operation times of the starting motor of the engine according to the temperature data. The single allowable running time, the minimum interval time and the actual running times correspond to each other, which shows that the starting times of the starting motor are required under the temperature data, the safe running time of the starting motor after each starting is ensured under the temperature data and the starting times, and the safe interval time between two running times, so as to ensure that the starting motor is not burnt.
As the temperature data increases, the single-shot allowed run time decreases and the minimum interval time increases. That is, in general, the higher the temperature of the engine coolant, the shorter the single-time permitted operation time of the starter motor, and the longer the minimum interval time.
And the execution module 230 is used for controlling the actual running times of the starting motor, controlling the single allowable running time of each actual running of the starting motor, and controlling the interval between every two adjacent running times to be the minimum interval time.
