Description

Control method and device of load simulation device for soft start test of cabinet Technical Field The invention relates to the field of soft start testing, in particular to a control method and a control device of a load simulation device for cabinet soft start testing. Background The soft start test is a key detection link before the cabinet leaves the factory and in the operation and maintenance process, and verifies the suitability, impact resistance and operation parameter stability of components such as a power supply module, a heat dissipation system, line connection and the like in the cabinet in the starting stage by simulating the real scene of the loaded start of the cabinet. In the soft start test process of the cabinet, the load simulation device is one of core test equipment, and has the function of simulating various load characteristics carried in the actual operation process of the cabinet, and the load working condition of the soft start stage of the cabinet is reproduced by outputting parameters such as specific power, voltage, current and the like. In an actual test scenario, the electrical characteristics of the core power output components of the load simulator are susceptible to changes in ambient temperature and its own operating temperature. Because the existing control method does not consider the influence of temperature factors on the output characteristics of the load simulation device, the test is directly started only after the basic parameter setting is completed before the test, so that the deviation between the actual output power of the load simulation device and the preset power occurs. The power deviation can cause the inconsistent load working condition and preset working condition based on the cabinet soft start test, and the judgment of key performance indexes such as the stability of the cabinet soft start current and the output adjustment capability of the power supply module is affected. Disclosure of Invention In order to eliminate temperature influence and ensure output stability of the load simulation device, the invention provides a control method and device of the load simulation device for soft start test of a cabinet. In a first aspect, the present invention provides a control method for a load simulator for soft start testing of a cabinet, which adopts the following technical scheme: A control method of a load simulation device for a cabinet soft start test comprises the following steps: When the load simulation device is not electrified, gear selection is carried out on the load simulation device according to a preset simulation gear scheme, and the current selected load power is recorded; acquiring the temperature value of components in the load simulation device in real time; When the temperature value of the component exceeds a preset reference operating temperature range, calculating temperature drift information according to the temperature value of the component and the reference operating temperature range; load deviation information is matched according to the temperature drift information, the current selected load power is corrected based on the load deviation information to obtain operation load power, and the operation load power is output on a control panel; Matching a temperature control adjustment scheme according to the positive-negative relation of the temperature drift information, and adjusting the temperature value of the component according to the temperature control adjustment scheme; And stopping the temperature control adjustment of the load simulation device when the running load power displayed by the control panel is consistent with the current selected load power, and entering a test waiting state. By adopting the technical scheme, before the soft start test is performed when the load simulation device is not electrified, the temperature of the switching power supply in the load simulation device is acquired, whether the switching power supply has temperature deviation is determined, and whether the power actually output by the load simulation device is consistent with the set current selected load power is determined. And under the condition of inconsistency, the system carries out temperature control adjustment on the switching power supply, and only when the running load power displayed by the control panel is consistent with the current selected load power, the load simulation device is allowed to be connected with the cabinet and the cabinet is subjected to soft start test. The method can eliminate the temperature influence, thereby guaranteeing the output stability of the load simulation device. Optionally, the temperature control adjustment scheme includes: When the temperature drift information is negative, temperature rise regulation and control are carried out, and the control components are started in a preset minimum power state; Continuously correcting the minimum power state at a preset power increasing speed to co
