3) firstly, lubricating on time, namely, a PLC detects the running circle number (information of a pulley circle number encoder) of a crown block pulley, when the running is not detected to a threshold value, the running is finished, when the detection reaches the threshold value, the next step is carried out, the actual temperature in an execution module and the actual temperature of a pipeline module are detected, the actual temperature is compared with the temperature threshold value set by a program, when the actual temperature is lower than the set temperature, a heat tracing band at the corresponding part is started to heat, the program is delayed for a certain time, the temperature is detected again, when the temperature exceeds the threshold value, the next step is carried out, a grease injection pump motor is started, then the PLC collects the information of a distributor and a pulse sensor, the time interval of each pulse is detected, if the preset value in the program is exceeded, the PLC sends alarm information to a touch screen, the blockage is displayed, a three-color indicator lamp of, next, acquiring the pulse number information of the distributor until the actually executed pulse number reaches a preset pulse numerical value, and then closing the grease injection pump by the PLC controller to finish the automatic lubrication mode; when the time reaches the lubricating time set by the PLC, the PLC starts the grease injection pump to lubricate according to the preset lubricating amount, which is embodied in the pulse number of the distributor, the pulse sensor senses a pulse and pumps Vml correspondingly;
4) secondly, quantitative lubrication, the PLC detects the number of pulses pumped in the same day, the PLC accumulatively calculates the number of pulses pumped, when the detection reaches a threshold value, the operation is finished, when the detection does not reach the threshold value, the next step is carried out, the actual temperature in the execution module and the actual temperature of the pipeline module are detected, the actual temperature is compared with the temperature threshold value set by a program, when the actual temperature is lower than the set temperature, the heating belt at the corresponding part is started, the program is delayed for a certain time, the temperature is detected again, when the temperature exceeds the threshold value, the next step is carried out, the grease filling pump motor is started, at the moment, the PLC collects the information of a distributor and a pulse sensor, the time interval of each pulse is detected, if the preset value in the program is exceeded, the PLC sends alarm information to a touch screen, the blockage is displayed, and a three, if the time does not exceed the preset value, the next step is carried out, the pulse number information of the distributor is collected until the actually executed pulse number reaches the preset pulse value, at this time, the PLC controller closes the grease injection pump, and the automatic lubrication mode is ended; the PLC controller collects a pulley turn number encoder, and when the number of running turns of a pulley ring of a motorcycle reaches a preset turn number threshold value N, the PLC starts a grease injection pump to lubricate according to a preset pumping quantity;
5) supplementing lubrication, when the system runs to a certain preset time point, carrying out the next step, detecting the actual temperature in the execution module and the actual temperature of the pipeline module, comparing the actual temperature with a temperature threshold value set by a program, starting a heat tracing band at a corresponding part for heating when the actual temperature is lower than the set temperature, delaying the program for a certain time, detecting the temperature again, carrying out the next step when the temperature exceeds the threshold value temperature, starting a grease injection pump motor, acquiring information of a distributor and a pulse sensor by a PLC (programmable logic controller), detecting the time interval of each pulse, sending alarm information to a touch screen by the PLC if the time exceeds the preset value in the program, displaying blockage, lighting a three-color indicator lamp of the execution module, carrying out the next step if the time does not exceed the preset value, acquiring the pulse number information of the distributor until the actually executed pulse number reaches the preset pulse value, at this time, the PLC closes the grease injection pump, and the automatic lubrication mode is ended; that is to say, at a certain set time point, the PLC calls whether the number of the pumping pulses on the day reaches the preset pumping number, if the number of the pumping pulses reaches or exceeds the preset pumping number, the operation is finished, and if the number of the pumping pulses does not reach the preset pumping number, the PLC starts the grease filling pump until the pumping number reaches the requirement.
6) One-bond lubrication as described in step 1): pressing a key lubrication button on the execution module, starting the grease injection pump by the PLC, and carrying out single quantitative pumping according to the preset pumping amount;
7) forced lubrication described in step 1): when a forced lubrication button is pressed, the grease injection pump skips the control of a PLC, and is directly started to pump oil for lubrication or fault detection;
8) the touch screen module is responsible for carrying out parameter setting, operation and state display to the system, and the setting content has:
1. pumping amount per pulse: v ml;
2. minimum fault detection time per pulse is txs；
3. The number n of parallel outlets;
4. temperature threshold value t for starting heat tracing belt in box1；
5. Temperature threshold value t for starting pipeline heat tracing band2；
6. The threshold value N of the number of turns of the crown block pulley is set;
7. minimum amount of lubrication per day;
8. number of automatic pumping pulses nx；
The state display contents include:
1. performing temperature display in the module box;
2. displaying the temperature of the pipeline;
3. a blockage alarm display;
4. low liquid level alarm display;
5. displaying the running state;
6. whether the internet of things is online.
