The simulation in the embodiment mainly simulates the actual operation of the photovoltaic power station tracking bracket by controlling the rotation of the 150 slewing drivers. Wherein, drive arrangement includes motor and gyration reduction gear.

Exemplary, full scene verification: and verifying whether the strong wind mode, the strong rain mode, the strong snow mode, the flat-down mode and the cleaning mode can be realized, namely, whether the machine rotates to a specified angle.

The multifunctional integrated test method for the photovoltaic bracket array further comprises the following steps:

Exemplary, full complement compatibility validation: whether the communication frequency bands are compatible (the frequency bands of each country are different), and whether the wireless and wired communication are compatible. If the SCADA system can send out a command and receive data, the specific value is analyzed to indicate that the communication is smooth, and the communication frequency band can be compatible.

Exemplary, full-specification high-capacity validation: each revolution represents one subarray, and the simulation of 150 revolutions represents a plurality of subarrays on site, so that high-capacity verification is realized.

Exemplary, all-weather long-term stability validation: every half hour, the rotation is performed back and forth, and the back and forth are equivalent to the action to be performed in actual day, and long-term stability is verified.

By way of example, the self-development software SCADA realizes function instructions and all function verification, actively sets an operation mode, and automatically collects environment data and operation states.

Specifically, laboratory environment data are collected, and as the platform is built in a laboratory, wind and temperature can be simulated in the laboratory. The simulated environmental data mainly refers to verifying whether the data fed back by the sensor are accurate, such as a temperature and humidity sensor and an anemometer.

For example, the accuracy of the sensor may be obtained as long as the control room can issue a command, receive data, and resolve to a specific value.

The functions that can be tested include: a strong wind mode (driving the photovoltaic panel to lie flat or to form an angle with the horizontal plane), a heavy rain mode (turning back and forth at a small angle), a strong snow mode (turning to a limit angle), a flat mode, a cleaning mode, a manual setting mode, and the like.

With respect to the lifetime of the swing drive, the swing drive can be tested for 20 years of actual operation within a few months.

wherein the photovoltaic bracket array comprises at least two subarrays. In addition, in order to test the stability of the whole software system, the data of one subarray is copied to other numbered positions of the communication point table, so that the background considers that other numbered control boxes also have data, and one subarray (comprising 150 AI control boxes and rotary drives) can be simulated into a plurality of subarrays.

In this embodiment, there are 150 slewing drives and an AI control box. One subarray can be configured according to the needs, and in a practical scene, the number of signal coverage areas of the communication box is based. The motor, the slewing drive and the AI control box are regarded as a whole, and each sub-array comprises a plurality of whole bodies.

The operation parameters of one control box are mapped to the storage positions of other numbered control boxes in the point table of the communication box by a software processing method, so that the whole subarray (150 control boxes) data can be acquired by the background when the point table is acquired. By the method, a plurality of subarrays can be simulated in a laboratory, and data of a power station can be simulated and acquired under the condition that the number of laboratory trackers is limited. In this way, simulation tests can be performed in a laboratory environment before implementation into a power plant.

The AI control box is connected with the driving device in a one-to-one correspondence manner, controls the driving device to operate based on the test instruction, and comprises the following steps:

The step of feeding back the test data of the communication box to the SCADA server through the communication box so as to enable the SCADA server to acquire a test result comprises the following steps:

the test data of the communication box comprise the environment test data.

Specifically, the tests under different modes and/or different periods, such as the tests under different modes, specifically include: a strong wind mode (driving the photovoltaic panel to lie flat or to form an angle with the horizontal plane), a heavy rain mode (turning back and forth at a small angle), a strong snow mode (turning to a limit angle), a flat mode, a cleaning mode, a manual setting mode, and the like.

Specifically, the accuracy of the environmental test data is verified by using the reference environmental data of the heavy rain mode as a verification standard through the SCADA server, so as to determine the accuracy of each sensor.

The simulated environmental data, namely the reference environmental data of the heavy rain mode, mainly refers to verifying whether the data fed back by the sensor are accurate.

Specifically, the small angle in this embodiment is a preset angle set according to the requirement.

For example, because a small angle of back and forth rotation enables the raindrops on the drive to be better swept, the effect on the photovoltaic power plant is enormous if this function is defective, and therefore it is necessary to test this function.

In this embodiment, if a certain driving device does not perform the small-angle back-and-forth rotation or the rotation is abnormal, it is determined that the small-angle back-and-forth rotation function of the driving device is defective, and the driving device in the same batch as the driving device needs to be returned to the factory.
