Professional wall mount tablets are usually installed in limited spaces, and their volume and weight are strictly controlled. The addition of a built-in battery will make the tablet larger and heavier, which will bring difficulties to installation and deployment. Secondly, the built-in battery will affect the heat dissipation performance of the tablet. Professional wall mount tablets generate a certain amount of heat during long-term operation, and the heat dissipation system is designed precisely.
The built-in battery will occupy the internal space of the tablet, affecting the circulation of air and the heat dissipation effect. Excessive heat accumulation will reduce the performance of the tablet and even damage the internal components, affecting the service life of the equipment. In addition, the built-in battery will also increase the complexity of the internal circuit design of the tablet. The conversion and switching between PoE power supply and battery power supply require additional circuit modules, which increases the probability of circuit failure and reduces the stability of the equipment.
2.2 Impact of Battery Maintenance Cost on Professional Equipment Operation
Battery maintenance cost is an important factor that cannot be ignored in the operation of professional equipment. The built-in battery in PoE-battery hybrid power has a limited service life and needs to be replaced regularly. For professional wall mount tablets that are usually installed in high or hard-to-reach positions, the replacement of built-in batteries requires a lot of manpower and material resources.
During the replacement process, the equipment needs to be disassembled and reinstalled, which not only takes time and effort but also may cause damage to the equipment or affect the normal operation of the surrounding systems. In addition, the storage and transportation of batteries also require certain costs and safety measures. The improper handling of waste batteries will also bring environmental pollution risks and corresponding handling costs.
Moreover, the performance of the battery will gradually degrade during use. The decrease in battery capacity and performance will affect the backup power effect of the equipment. In order to ensure the reliability of the backup power supply, regular testing and maintenance of the battery are required, which further increases the maintenance cost. For professional users who pursue low operation and maintenance costs, the high battery maintenance cost makes them reluctant to adopt PoE-battery hybrid power.
2.3 Instability of PoE-battery Hybrid Power Supply System
Compared with a single power supply mode, the PoE-battery hybrid power supply system has higher complexity, which leads to lower stability. The switching process between PoE power supply and battery power supply is a key link that is prone to problems. If the switching circuit fails or the switching logic is unreasonable, it may cause instantaneous power interruption or voltage fluctuation, which will affect the normal operation of the professional wall mount tablet.
For example, in the process of switching from PoE power supply to battery power supply due to power failure, if the switching is not timely, the tablet may shut down unexpectedly, resulting in the loss of important data. In addition, the compatibility between the PoE power supply module and the battery management module is also a problem that needs to be solved. If the two modules are not well compatible, it may cause mutual interference, affecting the normal operation of the power supply system.
In professional application scenarios that require high stability, even a small power supply fluctuation may have serious consequences. Therefore, the instability of the PoE-battery hybrid power supply system is another important reason why professional wall mount tablets rarely adopt this solution.
2.4 Advantages of Single PoE Power Supply in Professional Scenarios
Compared with PoE-battery hybrid power, single PoE power supply has more obvious advantages in adapting to professional wall mount tablet applications. Firstly, single PoE power supply has a simple structure and high stability. It does not need additional battery modules and switching circuits, which reduces the probability of failure.
Secondly, single PoE power supply can realize the simultaneous transmission of power and data through network cables, which simplifies the installation and deployment process. Professional wall mount tablets usually need to be connected to the network for data transmission. The use of single PoE power supply can reduce the number of cables, making the installation environment more tidy and easy to manage.
Thirdly, single PoE power supply has good scalability. It can be easily integrated with the existing network system, facilitating the centralized management and maintenance of equipment.
