Description

TECHNICAL FIELD

[0002] At present, as an important detection device, the chemiluminescence immunoassay analyzer has been widely used in clinical diagnosis and scientific research experiments. The existing chemiluminescence immunoassay analyzer usually directly connects the power supply to each functional module.

In addition, since the power supply is directly connected to multiple functional modules, short circuit often occurs. Once a short circuit occurs, not only will the functional modules that need to be powered be damaged, but also safety accidents may occur, threatening the safety of the operator and the normal operation of the equipment.

However, in actual application, the delay switch circuit cannot respond to the demand for sample detection in a timely manner, and once a short circuit occurs in the functional modules connected to the same power supply, all functional module devices will be damaged, resulting in the loss of detection data and affecting the detection result. Therefore, there is an urgent need to provide a power supply control system applied to a chemiluminescence immunoassay analyzer to solve the problem of device damage and detection data loss caused by short circuit.

DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved in the present application more clear, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0026] Please refer to Figures 1-2 A structural schematic diagram of a power control system applied to a chemiluminescence immunoassay analyzer is provided for the embodiments of the present application, which comprises an AC power supply 1, and further comprises:

[0027] The power conversion circuit 100 comprises the pre-processing circuit 300 and the single-machine circuit 400 connected with the AC power supply 1, and is used for converting AC power into DC power; the pre-processing circuit 300 comprises the emergency stop button 7, the NO pin of the emergency stop button 7 is connected with the first switching power supply 4 and the second switching power supply 10, the NC pin of the emergency stop button is respectively connected with the third switching power supply 9 and the fourth switching power supply 8, and is used for powering off when the current is overloaded;

[0028] The power supply circuit 200 comprises the circuit adapter plate 12, the circuit breaker 11 and the serial-to-parallel chip 13 connected with the circuit adapter plate 12, and the circuit adapter plate 12 is an IO board, a heating and refrigeration module 16 and a motor drive board 17. Specifically, the first switching power supply 4, the second switching power supply 10, the third switching power supply 9 and the fourth switching power supply 8 are used for converting AC power into DC power. It is worth noting that the IO board, the heating and refrigeration module 16 and the motor drive board 17 are all existing functional modules of the chemiluminescence immunoassay analyzer, wherein the IO board is responsible for receiving sample detection data detected by the chemiluminescence immunoassay analyzer and transmitting control instructions; the heating and refrigeration module 16 is used for keeping the reagents and samples in the chemiluminescence immunoassay analyzer to react at a constant temperature, so as to ensure the accuracy of the detection result; and the motor drive board 17 is responsible for controlling various motor movements in the chemiluminescence immunoassay analyzer.

[0029] The power supply conversion circuit 100 and the power supply circuit 200 are used to control the power supply of each functional module. Firstly, the emergency stop button 7 is connected between the AC power supply 1 and each switching power supply. In an emergency, the emergency stop button 7 is pressed, and all switching power supplies will be powered off at the same time, effectively preventing the impact of sudden current interruption on the circuit. Secondly, the circuit breaker 11 is provided in the power supply circuit 200. When the circuit is short-circuited, the circuit breaker 11 connected with each switching power supply and each functional module will be directly disconnected, thereby isolating the power supply conversion circuit 100 and the power supply circuit 200, ensuring the safety of the equipment in each functional module and avoiding the loss of detection data. Finally, each functional module is isolated by the serial-to-parallel chip 13, avoiding damage to other functional modules due to short-circuit of a certain functional module.

[0030] Specifically, the C pin of the emergency stop button 7 is a common pin, which is the common connection point of the NO pin and the NC pin. The NO pin of the emergency stop button 7 is a normally open pin, and the contact is open. The NC pin of the emergency stop button 7 is a normally closed pin, and the contact is normally closed before the switch is pressed. When the equipment is running normally, the C pin and the NO pin of the emergency stop button 7 are conductive, so that the first switching power supply 4, the second switching power supply 10, the third switching power supply 9 and the fourth switching power supply 8 are conductive, and then the IO board, the heating and refrigeration module 16 and the motor drive board 17 are powered through the power supply circuit 200. When an emergency occurs, the NC pin of the emergency stop button 7 will be disconnected, so that the first switching power supply 4, the second switching power supply 10, the third switching power supply 9 and the fourth switching power supply 8 are instantaneously turned off.

[0031] In an alternative embodiment, the pre-processing circuit 300 comprises a first air switch 2 and a first filter 3, one end of the first air switch 2 is connected to the AC power supply 1, the other end is connected to the first filter 3, the first filter 3 is connected to the first switching power supply 4, the first air switch 2 is used to automatically disconnect the circuit when the current exceeds the set value, and the first filter 3 is used to remove the noise and interference in the AC power supply 1. Here, by setting the first air switch 2 and the first filter 3 between the AC power supply 1 and the first switching power supply 4, the smooth transmission of current in the circuit is ensured, and the size of the current is limited by the first air switch 2 to prevent the circuit from being damaged due to current overload. At the same time, the first filter 3 is used to remove the noise and interference in the AC power supply, reducing the noise generated during AC transmission, allowing the first switching power supply 4 to more efficiently convert AC to DC. In addition, the first filter 3 can also reduce the electromagnetic interference generated by the first switching power supply 4, thereby better stabilizing the output voltage. The pre-processing circuit 300 further comprises a second air switch 5 and a second filter 6, one end of the second air switch 5 is connected to the AC power supply 1, the other end is connected to the second filter 6, and the second filter 6 is connected to the emergency stop button 7. Here, the second air switch 5 and the second filter 6 are used to limit current and remove noise to ensure stable transmission of AC. Moreover, the design of connecting the second filter 6 next to the emergency stop button 7 can effectively prevent voltage transients caused by sudden power interruption of sensitive components when the emergency stop button 7 suddenly cuts off the power supply, avoiding damage.

[0032] Specifically, the IO board comprises a first IO board 14 and a second IO board 15, the pre-processing circuit 300 supplies power to the first IO board 14 through the power supply circuit 200, and the single-machine circuit 400 supplies power to the second IO board 15 through the power supply circuit 200. The IO board is responsible for receiving sample detection data and transmitting control instructions of the chemiluminescence immunoassay analyzer. With this dual-IO board design, the chemiluminescence immunoassay analyzer can still maintain operation when one of the IO boards is short-circuited. This design significantly improves the device's ability to respond to potential short-circuit faults, effectively protects sample detection data from damage, and ensures the continuous and stable operation of the device.

[0033] Specifically, a plurality of circuit breakers 11 are connected with the first switching power supply 4, the second switching power supply 10, the third switching power supply 9 and the fourth switching power supply 8 respectively, respectively protecting a plurality of switching power supplies, the plurality of circuit breakers 11 are connected with the circuit adapter plate 12, the circuit adapter plate 12 is connected with the serial port of the serial-to-parallel chip 13, and the circuit adapter plate 12 transmits the allocated current for the serial-to-parallel chip 13, and the serial-to-parallel chip 13 is used for receiving the distribution signal of the circuit adapter plate 12 and supplying power to each functional module according to the distribution signal. It is worth noting that the model of the circuit adapter plate 12 is not limited here, and can be set according to the actual situation. The model of the circuit adapter plate 12 of the present application is WGSW1_005_008_VERA. Here, the circuit adapter plate 12 is selected between the circuit breakers 11 and each functional module to distribute the current, so that each functional module can obtain stable power supply. Furthermore, the circuit adapter plate 12 can also isolate each functional module, so that when a functional module in the device is short-circuited, it will not affect other parallel functional modules, ensuring the reliability of the detection data and enhancing the safety of other functional modules.
