Detailed Description
The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.
In a communication station Monitoring System, for example, a PSMS (power supply Monitoring System) power equipment and an environment centralized Monitoring System of "emerson network energy limited" are adopted, a communication station bottom layer Monitoring structure thereof may be as shown in fig. 1. Wherein, the commercial power supplies power for the communication bureau station from the direction shown by the arrow. Under the condition that the commercial power is normally supplied, a single-pole double-throw Switch or ATS (Automatic Transfer Switch) 4 is at a position P1, and the commercial power supplies power for the communication station. When the mains supply is cut off, the single-pole double-throw switch or ATS 4 is in the position of P2, and the generator 1 supplies power to the communication station. When the mains supply returns to normal, the device can be automatically or manually switched to the position P1, and the mains supply supplies power to the device. The mains supply signal transmitter 6 can monitor the mains supply state, and the monitoring system 3 can obtain the mains supply state through a mains supply monitoring signal wire 7 connected with the transmitter 6; the monitoring system 3 is also capable of determining the power supply state of the switching power supply 2 of the communication station through the switching power supply monitoring signal line 5.
A flow chart of one embodiment of a generator condition monitoring method of the present invention is shown in fig. 2. Under normal conditions, the commercial power supplies power for the equipment, and the generator is used as a standby power supply of the equipment; when the commercial power supply is in a power failure state, the generator is started, and the generator is used for supplying power for the equipment instead.
In step 201, the power input status of the device is obtained. In one embodiment, the power input status of the device may be obtained via a monitoring signal line 5, as shown in FIG. 1.
In step 202, a mains supply state is obtained. In one embodiment, the transmitter is capable of collecting mains signals, monitoring mains voltage, frequency, etc. in real time. The state of the commercial power can be judged to be in power supply or power failure by acquiring monitoring information of the transmitter.
In step 203, the operation state of the generator is determined according to the power input state of the device and the mains supply state. Because the generator is used as a standby power supply of the equipment, the generator can be determined to be in operation when the mains supply state is abnormal and the power supply of the equipment is normally input.
By the method, the running state of the generator can be judged by utilizing the monitored power supply state of the commercial power and the power input state of the equipment, so that the running state of the generator can be monitored in real time, the field investigation of a non-intelligent generator is avoided, and the manpower and material resources are saved while the efficiency is improved.
In one embodiment, the generator operation state may be determined by means of logic judgment according to the obtained mains supply state and the power supply input state.

In one embodiment, the following may be expressed according to the formula:
C＝A or B

In one embodiment, as shown in fig. 1, the monitoring system may acquire the power input state of the device through a switching power supply monitoring signal line connected to the switching power supply 2; the mains supply state can be determined by acquiring the mains supply signal collected by the transmitter 6. By the method, the running state of the generator can be monitored without changing the structure and the device of the monitored equipment end, and the method is favorable for quick and low-cost use.
In one embodiment, some of the device terminals, such as some small-sized communication stations, only monitor the switching power supply, but do not monitor the mains supply state. For these equipment terminals, auxiliary hardware devices are required to be added, and as shown in fig. 3, a mains state monitoring relay 8 is added to the mains input terminal as shown by an arrow. The output end of the normally open dry contact of the relay 8 is connected with the preset channel of the switch power supply 2, and the monitoring system 3 can judge whether the relay 8 is attracted or not by monitoring the input signal of the preset channel of the switch power supply 2, so that the state of the mains supply is determined. In one embodiment, the logic to determine may be:

In another embodiment, the mains supply state may be determined by obtaining an input signal of a predetermined input channel of the switching power supply, the predetermined channel of the switching power supply being connected to an output of a relay, a coil of the relay being located at the mains supply terminal.
In step 403, the generator operation state is determined according to the power input state and the mains supply state.
In step 404, the generator operation duration within a period of time is determined according to the generator operation state monitored in real time. In one embodiment, the running state of the generator may be counted, for example, running time of the starting motor may be counted by using report counting software.
In step 405, a reasonable fuel consumption of the generator is determined based on the operating time of the generator, the power of the generator and the fuel consumption rate. In one embodiment, the following may be expressed according to the formula:
Q＝T*P*B

At present, when the oil consumption of the generator is determined, a manager must go to the site and check the actual oil consumption by checking the power generation timer of each generator, so that the real-time performance is poor, the efficiency is low, and the operation is very troublesome; for some mobile generators without a generator timer, the length of the run time cannot be determined at all. By the method, the reasonable oil consumption of the generator can be determined without on-site investigation, and on one hand, the residual oil quantity of the generator can be estimated in real time; on the other hand, the method can be compared with the oil consumption reported manually, so that abnormal conditions can be found in time, and the loss caused by the phenomenon of 'leakage and leakage' is reduced.
